January 28, 1997 Part 1 Part 2
24 MR. ROOSCOLLINS: Let me ask a different
question.
25 Let's assume, as time goes by, that habitat
conditions trend
0170
01 toward recovery. If I may use as a verb,
the noun that is
02 used throughout your testimony. Let's
assume that the fish
03 population does not trend towards that
objective.
04 Where in the
Monitoring Plan do you have a protocol to
05 address that circumstance and to evaluate
whether the
06 Restoration Plan is working as intended on the
fishery?
07 MR. HUNTER:
I guess we don't. I guess I have assumed
08 all along that if we got to that point, if it
was 2014, and
09 first, let me say, that if this flow regime
is
10 implemented and it does do what we expect it to
do, I have a
11 hard time imagining the circumstances under
which these fish
12 populations would not be met. I just can't
imagine that
13 situation.
14 But if that did
occur, then I assume when this Board
15 reconvened in 2014 that they would take an
action to remedy
16 that situation.
17 MR.
ROOSCOLLINS: Let me turn to a different issue,
18 namely the place of pre1941 conditions in the
Monitoring
19 Plan. Let me draw your attention to Los
Angeles Exhibit 31,
20 Page 3, end of the first full paragraph.
Most of the 18
21 characteristics, referring to the RTC
characteristics, will
22 be monitored to follow future trends.
Which of those 18
23 characteristics will not be monitored under your
monitoring
24 plan?
25 MR. HUNTER:
Invertebrates, for one.
0171
01 MR.
ROOSCOLLINS: Are there others?
02 DR.
KAUFFMAN: Aquatic vegetation.
03 MR. HUNTER:
I don't believe there is monitoring on
04 spring flows. I think those are the only
three.
05 MR.
ROOSCOLLINS: Next issue, which is how this plan
06 proposes to take advantage of the monitoring
data collected
07 by Los Angeles and also by the Restoration
Technical
08 Committee through its consultant from 1987 to
the present.
09 I preface my
questions by saying I saw the term
10 "baseline" used in various places in
different ways in the
11 Monitoring Plan. So, I am uncertain
whether you intend to
12 use any of the monitoring data collected during
that period
13 for the purpose of assessing where we are in
1987, once this
14 Board approves the Monitoring Plan.
15 So let me put the
question to you. How does this plan
16 propose to use that data for the purpose of
evaluating
17 recovery of these streams?
18 DR.
KAUFFMAN: That would be all data collected since
19 1987?
20 MR.
ROOSCOLLINS: Yes. I am referring
specifically to
21 the data described on Page 3 of Los Angeles
Exhibit 22,
22 where you state that one of your first tasks is
to collect
23 the data previously collected by others. I
understand
24 that. I don't understand what
follows.
25 How does this plan
propose to use the data collected by
0172
01 Los Angeles and the restoration consultant prior
to the
02 issuance of D1631?
03 DR. BESCHTA:
I think it would have to be on a
04 casebycase basis. For example, stream
temperature data
05 could be used whenever it had been collected as
a baseline
06 condition. Let's suppose the stream
temperature data did
07 not hit the warmest time of the year. So
we are trying to
08 figure out what is happening with regard to
changes and
09 stream temperatures in recent times. If we
monitor
10 temperatures now on a more continuous basis, we
will have a
11 more holistic view of what is going on.
We'll have to go
12 back and utilize that earlier data, but we have
13 qualifications on it. I think that is
probably true of
14 almost every data set that we may end up looking
at, is that
15 it would have to looked at within the context of
the
16 measurements that are going to take place.
It may be very
17 valuable and it may be less than very
valuable.
18 MR.
ROOSCOLLINS: Dr. Beschta, before I ask my next
19 question let me offer a very brief editorial
comment.
20 I appreciate the
tremendous difficulty of the job which
21 this monitoring plan represents. My
questions are not
22 intended to suggest that it was an easy
job. What I am
23 trying to get at is what Los Angeles has offered
to this
24 Board for approval, leaving aside your opinion,
how you
25 would treat temperature data in some future
scenario? What
0173
01 do Los Angeles Exhibits 22 and 23 say will be
done with the
02 data collected prior to the adoption of Decision
1631?
03 DR. BESCHTA:
I guess someone else will have to
04 answer, 'cause I tried.
05 MR.
ROOSCOLLINS: I am asking for a reference to a
06 page in Exhibits 22 and 23 to show the treatment
of that
07 existing data.
08 MR.
KAVOUNAS: I don't believe you will find a
09 reference to a page because there is not
reference to any
10 page. The reason for that is exactly as
Dr. Beschta
11 explained. It depends on the data that you
find. If I can
12 use his term, the quality of the data, if it is
usable.
13 Then you would have to make an evaluation on the
spot,
14 whether you can or can't use it on a
casebycase basis.
15 MR.
ROOSCOLLINS: Mr. Kavounas, where in Exhibits 22
16 and 23 do you establish a protocol or method for
evaluating
17 the usability of the data collected before the
adoption of
18 Decision 1631?
19 MR.
KAVOUNAS: It is, I guess, referred to on Page 3,
20 the very page you are looking at, on the first
bullet, where
21 it says:
22
Purging most, but keeping organized the best
23
and most useful data.
(Reading.)
24 MR.
ROOSCOLLINS: You understand the parties disagree
25 rather violently regarding what the best data
may be?
0174
01 MR.
KAVOUNAS: I would hope not.
02 MR.
ROOSCOLLINS: Let me move to a different
issue,
03 specifically, analysis of trends in recovery,
Exhibit 31,
04 Page 5.
05 MR. HUNTER:
Can I ask a question, please?
06 MR.
ROOSCOLLINS: You may direct your question to the
07 Chair.
08 CHAIRMAN
CAFFREY: Mr. Birmingham, you have a witness
09 raising his hand over here. I am not sure
how we handle it.
10 MR.
BIRMINGHAM: I am confident it is a good
11 question.
12 MR. HUNTER:
I am sorry for being so stupid, but if you
13 could I think these are the Blue Book and
White Book. If
14 you could tell me what number is the White Book
and what
15 number is the Blue Book, it would help us a
lot.
16 MR.
ROOSCOLLINS: My apologies. If it would be
more
17 helpful, I will use the terminology White and
Blue Book.
18 DR.
KAUFFMAN: White is 22 and Blue is 23. Direct
19 testimony is 31.
20 MR. HUNTER:
That is wonderful.
21 CHAIRMAN
CAFFREY: I like White and Blue myself.
22 Go ahead, Mr.
RoosCollins.
23 MR.
ROOSCOLLINS: Mr. Hunter, I assure you I had no
24 intentions usually attorney's
numerology. Let me ask you
25 about trend analysis.
0175
01 Exhibit 31, which
is your written testimony, Page 5,
02 includes a section entitled, Expected Trends for
the
03 Monitoring/Evaluation Plan.
04 Does this plan
monitor trends in the recovery of the
05 various attributes which we have already
discussed?
06 DR.
KAUFFMAN: Yes.
07 MR.
ROOSCOLLINS: On Page 9, in the third
full
08 paragraph, you state:
09
A significant difference between monitoring
10
trends and monitoring processes is the type
11
of independent variable plotted on the X Axis
12
in the analysis. (Reading.)
13
And you continue to explain that.
14
Both are needed in this monitoring plan.
15
(Reading.)
16 Does that mean
that this plan monitors trends and
17 processes?
18 DR.
TRUSH: Yes.
19 MR.
ROOSCOLLINS: What is the difference?
20 DR. TRUSH:
The trends are response to the process. In
21 other words, if we tracked channel confinement
or, if you
22 wanted to, width, what produced that change in
width was not
23 just one simple thing. It was interaction
of vegetation and
24 the flows and everything else. So that, if
the attributes
25 are functioning the way we think they, and we
are doing that
0176
01 in the Monitoring Plan, as well, getting right
at the
02 process, the result of those working in a very
complex way,
03 are these morphologic changes or changes in
riparian
04 vegetation. So, we are plotting those
trends and assessing
05 attributes.
06 MR.
ROOSCOLLINS: Let me preface my next question by
07 reference to a memory shared with Dr. Beschta
and Dr.
08 Kauffman, although not with the esteemed Members
of this
09 Board, and that is the 1992 hearing before Judge
Finney
10 regarding a monitoring plan then proposed by Los
Angeles.
11 As I recall, there
was considerable disagreement among
12 the experts what statistical protocols to use to
monitor
13 various trends. So, let me ask the
question to you
14 directly.
15 Where in the White
and Blue Books do you state the
16 statistical or other analytical protocols you
will use to
17 analyze the trends and the processes which we
just
18 discussed?
19 MR.
BIRMINGHAM: Who is that question directed to?
20 Dr. Kauffman or Dr. Beschta or Dr. Trush
21 MR.
ROOSCOLLINS: Any member of this panel is free to
22 answer this question.
23 DR. TRUSH:
We stated in the Monitoring Plan we are
24 using representative reaches for looking at
various, and
25 what I am mostly working on, alluvial
processes. And there
0177
01 we've got it we aren't sampling. We
are taking
02 crosssections in defined places with an
intention in mind
03 of point bar, straight reach, and we are looking
at percent
04 movement, say, of particle sizes.
05 Now, true, we can
plot magnitude of flow on the X Axis
06 and the percent tracers moved on the Y.
There is going to
07 scatter there. We did not stipulate that
we will use a
08 regression to determine a linear
relationship. That is not
09 in there.
10 MR.
ROOSCOLLINS: Is this true of the other attributes
11 we have previously discussed?
12 DR. TRUSH:
Yes.
13 MR.
ROOSCOLLINS: Let me move on to site
selection,
14 Dr. Trush, since you raised that in anticipation
of my next
15 line of questioning, as well as in answer to my
question.
16 On Page 7 of the
White Book you state you refer to
17 representative reaches of Rush and Lee Vining
Creeks. You
18 refer in other places as well to those
representative
19 reaches. And in turn you identify what
those reaches are in
20 Figure 1 on Page 8.
21 Is that correct?
22 DR.
TRUSH: Yes.
23 MR.
ROOSCOLLINS: At least for Rush Creek.
24 With that as
foundation, let me ask you to turn again
25 to your written testimony, Los Angeles 31, Pages
6 through
0178
01 7. We begin with Page 6, where you discuss
rationale for
02 selective monitoring.
03
The monitoring plan will rely mostly on
04
representative
reaches. (Reading.)
05 And then turn to
Page 7, Point 3:
06
Sampling effort should be concentrated on
07
reaches with the greatest sensitivity to
08
geomorphic change and the clearest departures
09
from the pre41 channel morphology.
10
(Reading.)
11 Let me ask you to
relate that sampling focus back to
12 the choice of representative reaches shown in
the White Book
13 on Page 7.
14 Is it your
testimony that those reaches, so designated,
15 have the greatest sensitivity to geomorphic
change and the
16 clearest departures from pre41 channel
morphology?
17 DR. TRUSH:
As back up, we should look at the riparian
18 site. There are a number of statistical
methods and all
19 that that Boone discusses later. So, a lot
of when we
20 talk about the sampling should occur in the
representative
21 reach, we are really focusing a lot here on the
fluvial
22 processes. Because Boone's got some other
things going on
23 with the riparian.
24 Yes, those are,
and the reason why we selected those
25 reaches is, for one, that we went for alluvial
reaches in
0179
01 the stream channel. Channels, when their
bed and their
02 banks are adjustable, are most prone to the
disturbance, and
03 most sensitive to flow changes. Whereas,
the farther
04 upstream you go above the 395 bridge, you wind
up with
05 essentially nonerodable banks or fairly
unerodable banks,
06 and their response is much less.
07 So, we picked
those lower reaches that would be the
08 most sensitive to flow changes, realizing that
over the next
09 ten years or so, we want to be able to get at
the important
10 flows as a prescription. So, we picked
those areas that
11 would give us the most information on it.
12 MR.
ROOSCOLLINS: Let me then ask you specifically
13 about the representative reaches chosen within
Reach 4, as
14 shown on Figure 1 of the White Book.
15 Is it your
testimony, Dr. Trush, that R1 and R2, as
16 so designated, have the greatest sensitivity to
the change
17 you described and the greatest departure from
pre41
18 conditions?
19 DR. TRUSH:
The whole channel between R1 and R2 on
20 that figure, I can't say that this thousand feet
is that
21 much more susceptible to the next thousand feet
downstream.
22 We picked those two because they had some
interesting
23 features in them. There were some nice
point bars forming,
24 some primordial floodplains developing, and some
constant
25 information that we are using. Again, when
we talked about
0180
01 how we are going to use that monitoring data,
when you can
02 do a belly flop in any direction and be impinged
on a rebar
03 out there, somewhere. So we wanted to get
rid of most of
04 the stuff that is useless. It's been
poorly documented, so
05 we can't use it.
06 We want to get the
best crosssection. We looked at
07 that and some of these reaches have some pretty
good
08 documentation. I can't say between R1
and R2 that that
09 reach is less sensitive than R1 or R2.
We had other
10 criteria in mind. I can't say.
11 MR.
ROOSCOLLINS: Let me ask you then about the
12 establishment of transects within each
representative reach,
13 and here, frankly, the scientific jargon
somewhat befuddles
14 me.
15 Are you proposing
a specific distance between transects
16 in each representative reach for the purpose of
monitoring
17 all trends, or does the transect site vary
depending on what
18 you were monitoring?
19 DR. TRUSH:
It varies.
20 MR.
ROOSCOLLINS: I believe that you monitor or rather
21 you propose to establish transects every eight
feet on Rush
22 Creek for planned mapping?
23 DR. TRUSH:
No. There are two separate things going on
24 here. In the planned mapping, we propose
putting in rebar
25 approximately every 200 meters or 200 feet, 200
feet, simply
0181
01 so we can locate ourselves.
02 The
crosssections that are selected for the plan maps
03 are based on the morphology of the channel out
there. We'd
04 like to put several outside the bends, several
on the
05 straight reaches. The data that you
referring to, Bob could
06 address that.
07 DR. BESCHTA:
The data that is collected on eightfoot
08 separations, if you will, or every eight feet
along the
09 channel is attempting to get thalweg, the
deepest part of
10 channel, as well as wetted widths.
Essentially, it is a
11 complete inventory of fairly lengthy
reaches. Again,
12 looking at change through time. One of the
monitoring
13 variables is change through time. This
provides us a good
14 indication of the dynamics of the channel.
15 For example, in
the last twoandahalf years pool
16 frequencies, pool depths, wetted depths have all
increased
17 fairly significantly on the bottomlands of Rush
Creek. It
18 is through this kind of measurements now,
we don't have
19 sampling statistics involved because,
essentially, we are
20 measuring the bottom of that channel over a
twomile reach.
21 So, we will know very precisely the kinds of
changes that
22 are taking place.
23 MR.
ROOSCOLLINS: Let me move to my eighth and final
24 issue, which I will generally call adaptive
management.
25 Mr. Kavounas, let
me refer you to Page 127 of Los
0182
01 Angeles Exhibit 16, the Stream Restoration
Plan. This page,
02 I believe, is outside of Chapter 7, which you
have
03 previously testified has been withdrawn.
04 Mr. Kavounas, on
that page you state:
05
Results from the monitoring program will not
06
be included in these documents previously
07
described. Instead monitoring data will be
08
provided as a separate data, separate
09
document within eight months after
10
collection.
(Reading.)
11 Is that commitment
still part of the Monitoring Plan
12 submitted to this Board?
13 MR.
KAVOUNAS: It's the Department of Water and Power's
14 intention to keep the State Board apprised of
the progress
15 of restoration in the Mono Basin. I can't
tell you, and I
16 would have to ask the scientists, whether I will
be able to
17 deliver, eight months after the data has been
collected a
18 package to the State Board. If they think
that is doable,
19 then the commitment to the State Board still
holds.
20 MR.
ROOSCOLLINS: Let me ask a different question
21 then.
22 Do the White and
Blue Books set forth a different
23 reporting procedure for monitoring results?
24 MR.
KAVOUNAS: No, they do not. If there is to be
a
25 change in that, we did not go as far as
addressing that. I
0183
01 guess I could ask the scientists at this point
as any other
02 time.
03 Could I report to
the State Board eight months after
04 the data has been collected?
05 DR.
KAUFFMAN: If that is in the contract.
06 MR.
KAVOUNAS: Money becomes an issue. I am told
by
07 the scientists that, yes, that is
possible. And so I would
08 say the Department's commitment still holds,
that it is
09 unchanged.
10 MR.
ROOSCOLLINS: The record should reflect that Dr.
11 Kauffman's answer was, "Yes, eight months,
if it is in the
12 contract."
13 DR.
KAUFFMAN: If it was in the request for proposals
14 or for bids that that is what the requirements
of L.A.
15 Department of Water and Power is data
collection. Then the
16 contractor, the person doing the analysis, would
have to
17 produce or be in default.
18 MR.
ROOSCOLLINS: Let me turn now to Los
Angeles
19 Exhibit 31, Page 9, second full paragraph:
20
Adaptive management is not possible if only
21
responses, primary and secondary, are
22
monitored. There would be no timely response
23
to improve management prescriptions and few
24
quantitative recommendations for changing
25
management
prescriptions.
(Reading.)
0184
01 Stated in
affirmative, do the White and Blue Books
02 propose excuse me. Withdraw that
question.
03 Stated in the
affirmative, where do the White and Blue
04 Books describe the procedure for adaptive
management based
05 on your monitoring results?
06 DR. TRUSH:
There is no procedure outlined. There is
07 simply a monitoring plan collecting the data so
it would
08 allow adaptive management to take place.
As a scientist, I
09 didn't worry about all the various bureaucratic
ways that
10 decisions would be made. Simply, the
Monitoring Plan was
11 saying, "Look, these attributes are or are
not being
12 satisfied. You need to change the
science. It says you
13 need to change these flows to this in order to
make
14 attribute Number 4 happen. Now, what are
you going to do
15 about it?"
16 And as a
scientist, here.
17 MR.
ROOSCOLLINS: Mr. Chair, I see my yellow light is
18 on. I would like to conclude by making a
brief comment to
19 this panel as a whole.
20 MR.
BIRMINGHAM: Excuse me, Mr. Caffrey.
Throughout
21 his examination, Mr. RoosCollins has been
stating the
22 position of Cal Trout. I did not want to
interfere with his
23 crossexamination. But it many times took
on the form of
24 argument.
25 If Mr.
RoosCollins would like to make a statement to
0185
01 this panel, I am more than happy to make it
available
02 outside of the hearing room. But if he
wants to make
03 argument, then I would propose that he make it
at the time
04 he begins the presentation of his case.
05 CHAIRMAN
CAFFREY: When you say a statement, Mr.
06 RoosCollins, can you clarify? Is this
going to be
07 questions or what?
08 MR.
ROOSCOLLINS: No, Mr. Chair. I believe Mr.
09 Birmingham misconstrued my intention. I
merely wanted to
10 thank this panel for their very considerable
efforts to
11 struggle with the very hard issues which have to
be
12 addressed in the Monitoring Plan.
13 MR.
BIRMINGHAM: I would ask Mr. RoosCollins to put
14 that in writing he supports DWP's request to the
State Board
15 to approve these monitoring plans.
16 MR.
ROOSCOLLINS: I did not say the plan
complied
17 with Decision 1631, but I greatly appreciate the
efforts of
18 this panel and Los Angeles.
19 Thank you.
20 CHAIRMAN
CAFFREY: Mr. RoosCollins, we appreciate your
21 deference and completing your questions in the
time
22 allotted. You do understand, had you
needed more, we
23 certainly would have considered giving you more.
24 We appreciate your
helping us stay on schedule.
25 Thank you, sir.
0186
01 MR.
ROOSCOLLINS: Thank you, sir.
02 CHAIRMAN
CAFFREY: Let me just say then that we have
03 sent out a runner to make sure the cafeteria is
going to
04 stay open till about 4:00.
05 MR. FRINK:
Till 3:30.
06 CHAIRMAN
CAFFREY: Till 3:30. We are going to break
07 now. Let's make it about ten minutes, and
then we will come
08 back and continue the crossexamination of this
panel. We
09 will also have a little information about what
the schedule
10 looks like for tonight.
11
(Break taken.)
12 CHAIRMAN
CAFFREY: We will resume. We have one Board
13 Member taking care of other matters, who will be
joining us
14 soon. That is Ms. Forster.
15 Let me introduce a
staff person that I neglected to
16 introduce this morning. Melanie Collins is
at the front
17 table. I apologize, Melanie. I
didn't know you were going
18 to be here, and you have been here all
day. Welcome.
19 Before we get back
to the crossexamination, let's have
20 a little discussion about what the schedule is
going to be
21 for tonight. I have talked to my fellow
Board Members and
22 staff and a couple of you all, and in the
interest of trying
23 to get us out of here earlier in the evening
than a somewhat
24 lengthy dinner break will afford, I think what
we are going
25 to do is at 4:30 we will take a halfhour
break so that
0187
01 people can move their cars, and you will need
quarters, and
02 they have them. If you are going to park
on the street, and
03 use the parking meters, you will need quarters
till about
04 6:00.
05 Is that correct,
Mr. Johns?
06 MR. JOHNS:
That is correct.
07 CHAIRMAN
CAFFREY: If you don't have quarters on you,
08 please feel free to go next door and get some
change. We
09 will, as I say, break at 4:30 and come back at
5:00 and then
10 go till sometime between 8:00 and 8:30, whatever
constitutes
11 a reasonable break. The alternative would
have been to
12 break for dinner for an hour, an hour and a
half, and come
13 back and go later. And I think in the
interest of what
14 people have requested and just getting out of
here as early
15 as we can, let's go with that schedule.
16 MR. JOHNS:
Might be good to know that the garage here,
17 if you parked here, actually closes at 7.
If your car is in
18 there at 7:00, you will not get it out
tonight. That is why
19 it is important to move your car. So, if
you are in here,
20 you need to move your car to the street.
Then you will be
21 okay, unless someone breaks into it.
22 CHAIRMAN
CAFFREY: At 7:00 the attendant locks that
23 place up and he's gone, and you will have to
come in the
24 morning to get your car. So, I just want
to make sure
25 everybody understands all that.
0188
01 All right.
That will be the procedure. And let's go
02 to the Department of Fish and Game for
crossexamination of
03 these three panels.
04 MS. CAHILL:
Mr. Chairman, Mr. Dodge asked if he could
05 switch with us. We have no objection if
the Board does
06 not.
07 CHAIRMAN
CAFFREY: Is there what about Mary
08 Scoonover? Do you have an objection?
09 MS.
SCOONOVER: No.
10 CHAIRMAN
CAFFREY: Mr. Dodge would like to follow
11 California Trout. Is that going to be a
change in the
12 general procedure?
13 MR. DODGE: I
don't know if it is general, Mr.
14 Chairman. It is just for this panel right
now. We thought
15 it made sense.
16 CHAIRMAN
CAFFREY: Without objection, we will do that.

CROSSEXAMINATION
19 BY THE NATIONAL AUDUBON SOCIETY AND THE MONO
LAKE COMMITTEE
20
BY MR. DODGE
21 MR. DODGE: I
will stay with monitoring, if I may.
22 Dr. Trush, you
talked about the process. When did you
23 start drafting the revised monitoring plan?
24 DR.
TRUSH: I believe I first started it in
June. I
25 had a rough draft sometime in August.
0189
01 MR. DODGE:
Final draft when?
02 DR. TRUSH:
Final draft, that was definitely a
03 preliminary in August. I guess final
I am trying to
04 recall. Mid fall. And we still had
changes after that. We
05 had a bunch of comments and a lot of changes
after that.
06 The very final
one?
07 MR. DODGE:
Did you do a final draft before Dr.
08 Beschta and the others got involved?
09 DR. TRUSH:
Yes, a draft.
10 MR. DODGE:
You did?
11 DR. TRUSH:
Yes.
12 MR. DODGE:
My understanding of the purpose of a
13 monitoring plan, visavis a restoration plan,
typically the
14 Monitoring Plann is used to determine whether
you reached
15 your restoration goal.
16 Is that typically
true?
17 DR. TRUSH:
This is my first monitoring plan, so I
18 can't sounds evasive. I would think
that is common.
19 MR. DODGE:
Mr. Hunter, would you agree?
20 MR. HUNTER:
When I was working on the book that I
21 mentioned earlier, I found that almost nobody
did any
22 monitoring of stream restoration projects once
the project
23 was completed. There was neither the time
nor the money to
24 do any monitoring, so that there is I
suspect there has
25 been, actually, been very little monitoring in
stream
0190
01 restoration plans.
02 MR. DODGE:
When you did the October 1995 report, in
03 concept, you were talking about a monitoring
program which
04 would determine whether you reached a
restoration goal,
05 correct?
06 MR. HUNTER:
Yes.
07 MR. DODGE:
Correct, Dr. Trush.
08 DR. TRUSH:
At the time, yes, we thought.
09 MR. DODGE:
The DWP monitoring program does not tell us
10 that, correct?
11 DR. TRUSH:
Yes, because we realized that many of the
12 endpoints weren't functional. They
wouldn't serve as
13 reasonable objectives.
14 MR. DODGE:
The second purpose of a monitoring program,
15 as I understand it, is to determine whether to
adapt the
16 restoration program if the monitoring program
shows you are
17 not being successful.
18 Would you agree
with that, Dr. Trush?
19 DR. TRUSH:
Yes.
20 MR. DODGE:
Now, Dr. Trush, when you were doing the
21 October 1995 report, let me read you a section
of that,
22 Page 5.
23
We find the restoration objective, as stated
24
by the Superior Court, appropriate for
25
developing a restoration program and
0191
01
consistent with the requirement to
"restore"
02
as stated in D1631.
(Reading.)
03 Do you recall
that, sir?
04 DR. TRUSH:
Yes.
05 MR. DODGE:
So, basically, your goals in the October
06 '95 scientist report were consistent, you
thought, with both
07 Judge Finney's goal of reestablishing conditions
that
08 benefited the fishery prediversion and with 1631
goals?
09 DR. TRUSH:
Yes.
10 MR. DODGE:
And I think you already testified that the
11 present monitoring program does not have that
same goal,
12 correct?
13 DR. TRUSH:
No. Again, when we look at the goal of
14 the healthy, happy, stream it's done in context
of
15 past. And that is how we incorporated
the past channel
16 by looking at undisturbed flow regimes that
created that
17 previous channel morphology. So, we still
have the same
18 objective. It is just it's not as
clear, I think,
19 because we found that a simple approach here, is
your per
20 channel predisturbance is what we are going to
shoot for,
21 wasn't available to us.
22 MR. DODGE: I
am a little confused now.
23 DR. TRUSH: I
am, too.
24 MR. DODGE:
Is it your testimony that the monitoring
25 program you are proposing will determine whether
the
0192
01 restoration program has recreated or restored
the conditions
02 that benefited the fisheries
prediversions?
03 DR. TRUSH:
What it is going to do is to, first, plot
04 trends, and there is no final endpoint to many
of those
05 trends. The second is to show that the
primary
06 prescription, the flows, will create an alluvial
stream
07 channel, which is what the channel was prior to
the
08 disturbance.
09 Is that
10 MR. DODGE: I
don't think that answers my question. If
11 that is the best you can do, I will move on.
12 DR. TRUSH:
If you want to give it to me again, I will
13 take another shot at it, if you like.
14 MR. DODGE:
Is the Los Angeles monitoring program
15 designed to monitor whether the restoration
program restores
16 the conditions that benefited fisheries
prediversion?
17 DR. TRUSH: I
will yes, but you won't like. Again, if
18 you can't we are basing it on
processes. If the
19 processes are there, we will create those
conditions that
20 will be good for fish.
21 MR. DODGE:
Do you regard the in your mind, Dr.
22 Trush, is the goal that we are seeking, is this
a question
23 of science or a question of law, or do you have
an opinion
24 on that?
25 DR. TRUSH: I
am in dangerous ground here. I am a
0193
01 scientist. I will fall back on that.
02 MR. DODGE:
Referring again to your October 1995
03 report, Dr. Trush, let me read from Page 11 of
that. You
04 said there, and I quote:
05
Measurable goals are essential to evaluate
06
the progress of restoration and document
07
accomplishments of restoration. (Reading.)
08 Did you regard
then measurable goals to be essential?
09 DR. TRUSH:
Essential. And that is why we have the
10 attributes and mobility that bed on the average
once a year
11 and flooding of the floodplain. Those are
essential for us
12 to know whether the prescriptions that we do now
will lead
13 to a restored, alluvial channel.
14 MR. DODGE:
When you were working in October of 1995,
15 your measurable goals, as listed on Page 12 of
that report,
16 were totally different, weren't they?
17 DR.
TRUSH: Yes well, they were included, I
should
18 say.
19 MR. DODGE:
They included length of the main channel as
20 a measurable goal?
21 DR. TRUSH:
Yes.
22 MR. DODGE:
That is no longer a measurable goal?
23 DR. TRUSH:
Got me on that one. There are some that
24 are measurable.
25 MR. DODGE:
Sinuosity of the main channel, that is a
0194
01 measurable goal; isn't it?
02 DR. TRUSH:
The length of the channel, sinuosity,
03 because we have such a poor estimate of what the
sinuosity
04 is before and not something to pull off the
aerial photo, we
05 have no endpoint sinuosity. We can say it
will increase,
06 i.e., decrease slope. I have a more
technical way of
07 evaluating the change of meander wavelength than
simply a
08 wavelength. But you are right.
09 We did address
we did compare pre41 channel length
10 with the present plan.
11 MR. DODGE:
That is no longer in the DWP Monitoring
12 Plan, is it?
13 DR. TRUSH: I
think it is. It does say in the
14 Monitoring Plan, we will continue to monitor all
those
15 attributes, as I recall.
16 I won't be able to
find it, but
17 DR. BESCHTA:
If I could add in here, I guess, the
18 eight characteristics that are listed on Page 11
can all be
19 interpreted off of aerial photography, and we
are, indeed,
20 proposing aerial photography. So, at some
level you can get
21 at all of those eight characteristics through
time and keep
22 track of it.
23 MR. DODGE:
Does this monitoring plan attempt to
24 restore the prediversion conditions on those
eight
25 characteristics?
0195
01 DR. BESCHTA:
We are restoring a process that will
02 allow those characteristics to express
themselves.
03 MR. DODGE:
Will the restoration program be deemed a
04 failure if these eight measurable goals are not
met?
05 DR. BESCHTA:
They are not firm goals. They are not a
06 quantitative target in the sense that if you
don't hit one
07 of those, you are a failure.
08 MR. DODGE:
They are not a quantitative target. They
09 are looking at trends, right?
10 DR. BESCHTA:
One aspect of understanding recovery
11 would be looking at trends. So, if you
plot a change, for
12 example, in a characteristic through time, that
would be one
13 way of assessing or beginning to ask the
question. Bill has
14 indicated there are other ways of looking at the
data where
15 you plot a feature against a flow and ask the
same kind of a
16 question, but it is at a process level.
Both are legitimate
17 ways of asking recovery as to what is going
on.
18 MR. DODGE:
In October of 1995, Dr. Trush, it's true,
19 isn't it, that you were doing to measure success
or failure
20 of the restoration program against achievement
of these
21 eight measurable goals?
22 DR. TRUSH:
Actually, we were going to look at we
23 tried to look at all of them. Once we put
out that sort of
24 charge as the RTC scientists to the rest of the
consultants,
25 it soon became obvious that it wasn't going to
work. This
0196
01 is how we did start out. We did think we
could pull that
02 off, but we can't.
03 MR. DODGE:
Did your draft monitoring plan include
04 measurable goals?
05 DR. TRUSH: I
think by then I started to see the
06 impossibility of it. I have to go back and
check for sure.
07 MR. DODGE:
Did you bring a copy of it?
08 Q. DR. TRUSH: No.
I've got the draft of our management
09 plan, but I got all 14 versions on my
computer. But I don't
10 have it here.
11 MR. DODGE:
Dr. Trush, looking at Pages 9 and 10 of
12 Exhibit 31, if that is the right number, you've
got these
13 nine listed, as I understood your testimony,
desirable
14 stream attributes; is that correct?
15 DR. TRUSH:
Yes.
16 MR. DODGE:
Is the DWP flow regime that has been
17 recommended likely to achieve these, in your
judgment?
18 DR. TRUSH:
Yes.
19 MR. DODGE:
Didn't you, in October of 1995, recommend
20 higher flow regimes?
21 DR. TRUSH:
Yes.
22 MR. DODGE:
At that time, you felt that those higher
23 flow regimes were necessary to achieve these
attributes,
24 correct?
25 DR. TRUSH:
No. And the reason why is that because we
0197
01 were locked into this categorical perspective of
water years
02 we have dry, wet, medium. When we
selected a flow level
03 for a wet year, we went to the higher end as our
estimate,
04 our first guess, say 500, 600 versus 500 cfs for
mobilizing
05 the bed. I ran a bunch of counts and
depending on the
06 slight change in the slope and whatnot, I
could get 6 or I
07 could get 500 cfs as that measure.
08 When we looked at
all the water years, the specific
09 water years in a water category, many times
there was not
10 enough flow to answer that, because each water
year is so
11 different within a water year class. So,
we decided to drop
12 several of them, simply because we knew that
they are
13 impossible in a number of water year types, and
we had a
14 poor idea whether it would be 6 or 500.
15 I pictured myself
standing, sitting here right now,
16 having someone go to me, "600 would
mobilize an alluvial bar
17 but 550 wouldn't, Dr. Trush? And I can't
say that. And so
18 I went to the limit of what I thought,
500.
19 The second
assurance that we had in our flow
20 negotiations was that these criteria, these flow
levels that
21 we gave were minimums in those flow classes, in
those water
22 year types, that there would be a protocol for
showing how
23 those would be maximized in those water
years. That is kind
24 of a convoluted way of doing things. But
if we stay with a
25 water year classification way of dealing with
prescribing
0198
01 flows, we are going to have those sorts of rat's
nests.
02 MR. DODGE:
Would the protocol include encouraging
03 spills on Grant Lake?
04 DR. TRUSH:
Yes.
05 MR. DODGE:
That is one of your recommendations?
06 DR. TRUSH:
Yes.
07 MR. DODGE:
We talked a little bit about adaptive
08 management. In fact, in your April of 1996
comments, Dr.
09 Trush, you said this was the most important
aspect of the
10 monitoring program, correct?
11 DR. TRUSH:
Yes.
12 MR. DODGE:
How monitoring program guides future
13 decisions is the ultimate factor in success or
failure of
14 the program?
15 DR.
TRUSH: Yes. The reason why I put that
in there
16 is that as Mono Lake fills, we are going to
when Mono
17 Lake fills, many of these trends that we are
going to be
18 monitoring aren't going to be anywhere near
completion. It
19 is going to be adjusting width, much of the
riparian aspect.
20 It is not going to be set or in some kind of
equilibrium,
21 whatever that word means, by the time the lake
fills.
22 Once the lake
fills, there is going to have to be
23 decisions made, if we stick with 1631, of
reducing the
24 flows. And the urgency is to show before
then, if the 1631
25 flows are inadequate for maintaining channel
morphology.
0199
01 Then we wanted to be sure that the monitoring
data was there
02 to show why they were. So a more informed
decision could be
03 made.
04 MR. DODGE:
You said that adaptive management is key to
05 the success of the program. Do you regard
it as a defect
06 that DWP's proposed monitoring program does not
have the
07 specific procedure for adaptive
management?
08 DR. TRUSH: I
don't think that is part of the
09 monitoring program. That is another
concept to this whole
10 process. I could call it an adaptive
management plan and
11 conveniently by word separate that from
monitoring plan and
12 feel comfortable with that.
13 MR. DODGE:
But that adaptive management plan would
14 have to be created, correct?
15 DR. TRUSH:
That is up for L.A. and everyone else to
16 decide. I'm a scientist that says these
are the flows that
17 do what, to create restoration in the stream
channel. I am
18 trying to keep myself in that slot.
19 MR. DODGE:
If the decision were yours, would you have
20 an adaptive management procedure?
21 DR. TRUSH:
Yeah.
22 MR. DODGE:
Suppose as you are aware, my clients,
23 in extreme years, think Rush Creek should have
600 cfs, and
24 the Los Angeles proposal is in extreme years,
with the Lee
25 Vining Creek augmentation, give Rush Creek 500
cfs.
0200
01 Do you recall
that, basically?
02 DR. TRUSH:
Well, we can let David address that.
03 MR. DODGE:
Assume that to be true.
04 DR. TRUSH:
In some extreme years. This year it might
05 be 800. And other extreme years it could
be 500 or 450.
06 Again, because we are locked into these water
year
07 classifications, it is hard to come up with a
single number
08 like 500. That is what we came up with.
09 MR. DODGE:
We are talking minimum maintenance flows.
10 DWP's proposal for wet years was 500 and your
proposal last
11 October was 600, correct, minimum maintenance
flows?
12 DR. TRUSH:
Yes, but for the reasons I have already
13 given.
14 MR. DODGE:
By the way, you say 1997 is going to be a
15 big year. Would it be a smart thing to
monitor at 500 cfs
16 and 600 cfs in Rush Creek and see how the creek
does?
17 DR. TRUSH:
First of all, you won't be able to monitor
18 those two distinct flows. I wouldn't want
to wade it. And
19 most of the equipment and whatnot is
subsurface. We just
20 tried doing it at Trinity, and at 30,000 we
almost got
21 pulled off the bridge. We had locked
never mind. I am
22 story telling.
23 BOARD MEMBER DEL
PIERO: It would have been a
24 DR. TRUSH:
It was a wooden bridge and taking
25 everything with it, including our bed load
sampler.
0201
01 Personally, and,
again, I don't make that decision.
02 Whether L.A. would like me to do some monitoring
or not, I
03 will be doing some monitoring out there.
04 MR. DODGE:
My question is: Would it be a smart thing
05 to see what is happening at 500 cfs versus what
is happening
06 at 600 cfs?
07 DR. TRUSH:
Yes. But at discreet events. So, in other
08 words, that is why the Monitoring Plan for the
time frame
09 for looking at channel dynamics is, again,
vague. It says
10 not every year until the lake fills, but maybe
eight or ten
11 years, so we can get a range of events to get a
better
12 handle on what does what out there.
13 MR. DODGE:
Hypothetically, if this Board were to
14 determine that 500 cfs is the correct number in
Rush Creek
15 in a wet year, whether that is the right number
or the wrong
16 number, could be looked at in the monitoring
program,
17 correct?
18 DR. TRUSH:
It will provide an awful lot of yeah.
19 MR. DODGE:
If an adaptive procedure is written up,
20 then that could provide for a change from 500 to
600,
21 depending on what the facts show, correct?
22 DR. TRUSH:
The way I envisioned adaptive management,
23 yes.
24 MR. DODGE:
That is all I have on monitoring.
25 Mr. Hunter, if you
want to retreat to the back of
0202
01 MR. HUNTER:
It is an option. We thought you were
02 still shuffling your papers.
03 MR. DODGE:
Dr. Platts, we meet for the last
time.
04 DR. PLATTS:
Hopefully. Getting your last shot.
05 MR. DODGE:
Your testimony, do you have your testimony
06 in front of you, sir?
07 DR. PLATTS:
Yes, I do.
08 MR. DODGE:
Page 1, you say:
09
No stream diversions for irrigation purposes
10
will be made below the LADWP conduit on
11
Parker and Walker Creeks and only three
12
diversions will function on Parker Creek
13
above the conduit.
(Reading.)
14 Sir, are you aware
that there was irrigation in 1996
15 below Parker and Walker Creeks?
16 DR. PLATTS:
No.
17 MR. DODGE:
You weren't aware of that?
18 Let me show you a
letter dated June 27, 1992, from Mr.
19 Kodama, which I believe is the last written
matter I have
20 seen on that subject. And I ask you to
take a look at the
21 second page there. Right in there, sir.
22 Does that letter
indicate it is Los Angeles' policy to
23 irrigate in years where the runoff is 86 percent
of normal
24 or above?
25 DR. PLATTS:
That is what it says.
0203
01 MR. DODGE:
Do you know whether that policy has been
02 changed?
03 DR. PLATTS:
No, I do not.
04 MR. DODGE:
Thank you, sir.
05 Page 3 of your
testimony, Dr. Platts, let me read you a
06 portion I am going to refer to at the top.
07
Thus, only upstream passage of trout is in
08
issue. If a sediment bypass system is
09
constructed that allows free flow channel
10
conditions by the aqueduct diversion
11
facility, there will be potential fish
12
passage during the sediment bypass period,
13
which includes most of the year. (Reading.)
14 Did I read that
correct?
15 DR. PLATTS:
Yes, you did.
16 MR. DODGE:
Do you recommend such a system for sediment
17 bypass?
18 DR. PLATTS:
Yes. I recommend sediment bypass.
19 MR. DODGE:
Recommend a channel? Would that be a
20 preferred approach?
21 DR. PLATTS:
I don't know preferred approach, but it
22 would be, probably be, my preferred
approach.
23 MR. DODGE:
Do you think that continuous passage of
24 sediment is preferable to hauling it out and
putting it on
25 the stream bank every few years?
0204
01 DR. PLATTS:
Yes, I do.
02 MR. DODGE:
Why is that?
03 DR. PLATTS:
Because it fits the natural situation
04 better. Your sediment would be transported
mainly during
05 the high flow periods and during the
intermediate and low
06 flow periods when you want less sediment being
transported
07 down the channel because of spawning purposes or
rearing the
08 food biomass or such. It would just be
more compatible with
09 the natural processes that are going on.
10 MR. DODGE:
Also, if we were to haul out sediment by
11 truck and put it on the stream bank, that we
have to hear
12 from Dr. Kauffman, won't we, about the riparian
vegetation?
13 DR. PLATTS:
Yes. I don't condone that practice.
14 MR. DODGE:
Thank you.
15 Now, on this
channel that you said you preferred, could
16 that always provide fish passage?
17 DR. PLATTS:
It could.
18 MR. DODGE:
Are you familiar with Dr. Stine's proposal
19 to reopen the distributaries on Parker and
Walker Creeks?
20 DR. PLATTS:
No, I am not.
21 MR. DODGE:
Now, I hate to go so short with you, Dr.
22 Platts. I have only one more
question.
23 DR. PLATTS:
We can even miss that one, if you want
24 to.
25 MR. DODGE:
Are you aware that DWP proposes certain
0205
01 flows up until Mono Lake reaches its maintenance
level and
02 does not propose stream flows thereafter?
03 DR. PLATTS:
Yes. I think I have read that.
04 MR. DODGE:
Would you agree with me that the channel
05 maintenance flows set by this Board, whatever
they maybe,
06 should continue after Mono Lake reaches it
maintenance level?
07 DR. PLATTS:
There will need to be channel in answer
08 to your question, I do agree with you. At
that time,
09 though, there should be an evaluation on what
the channel
10 flow should be from that time on.
11 MR. DODGE:
Basically, isn't it a fact, sir, that the
12 flows needed by the creek, the channel
maintenance flows are
13 basically irrelevant to what the level of Mono
Lake is?
14 DR. PLATTS:
Yes. That is I would state that is
15 right. The flows are more relevant to what
the conditions
16 are in the stream, rather than the lake.
17 MR. DODGE:
In fact
18 DR. PLATTS:
You were going to ask only one question.
19 BOARD MEMBER DEL
PIERO: You got sucked in again,
20 didn't you?
21 MR. DODGE:
In fact, the ad hoc subcommittee that has
22 been referred to, which you were a member,
specifically
23 said at Page 4 of the memo, February 13th:
24
The flows necessary to maintain the stream
25
habitat and its dynamic systems while the
0206
01
level of Mono Lake is being restored do not
02
differ from those needed after Mono Lake is
03
restored.
(Reading.)
04 Do you remember
that?
05 DR. PLATTS:
Yes, I do.
06 MR. DODGE:
That was your opinion then, and that is
07 your opinion now?
08 DR. PLATTS:
It is not exactly my opinion.
09 MR. DODGE:
You were a member of the subcommittee?
10 DR. PLATTS:
Yes, but I didn't quite agree with
11 everything, as a scientist I always do. My
point on that
12 is, at that time it should be evaluated because
the flows
13 needed to build the stream and conduct the
processes, it
14 needs to build all these new terraces and
floodplains, may
15 be a little different once the stream is already
set and the
16 flows needed to maintain the habitat from that
time on. I
17 didn't want to be tied down that they would be
exactly the
18 same flow, because I really don't think they
are.
19 MR. DODGE:
Mr. Kavounas, Page 2 of your testimony,
20 you say
21 MR.
KAVOUNAS: Which testimony?
22 MR. DODGE:
The Stream Restoration, sir.
23 I want to focus
in, specifically, on this sentence:
24
LADWP did not adopt this plan, referring to
25
the Ridenhour plan, because it did not
0207
01
consider the restoration parameters
02
established by Decision 1631, and it would
03
have further reduced Mono Basin exports.
04
(Reading.)
05 Do you see that,
sir?
06 MR.
KAVOUNAS: Yes, I do.
07 MR. DODGE:
What restoration parameters did you have in
08 mind?
09 MR.
KAVOUNAS: I was referring to a passage that is
in
10 the October '95 Ridenhour Plan. Page 161
says:
11
Our maintenance flow recommendations were
12
drafted without consideration for, among
13
other things, provisions in State Board
14
Decision 1631.
(Reading.)
15 MR. DODGE:
Do you see anything in the Ridenhour Plan
16 that was inconsistent with D1631?
17 MR.
KAVOUNAS: In my opinion, yes.
18 MR. DODGE:
What was that?
19 MR.
KAVOUNAS: In my opinion, the Ridenhour Plan would
20 not permit DWP to export as much as the decision
allows it
21 to, and I feel that is inconsistent with the
decision.
22 MR. DODGE:
Export then is the key point?
23 MR.
KAVOUNAS: Primarily. And I also refer to Mr.
24 Allen's testimony for the other two parameters
that he
25 mentioned.
0208
01 MR. DODGE:
Let's talk about the export issue, sir.
02 Isn't it true that export is only an issue
posttransition?
03 By that I mean after Mono Lake reaches
6391.
04 MR.
KAVOUNAS: I am sorry if I don't understand your
05 question as phrased. Are you asking me if
it is true?
06 MR. DODGE:
Pretransition you could have the Ridenhour
07 flows and still have your exports; isn't that
true?
08 MR.
KAVOUNAS: My understanding is that is not
09 necessarily true.
10 MR. DODGE:
What is the basis of your
understanding?
11 MR.
KAVOUNAS: My understanding is that if you have a
12 succession of, perhaps, two years that are on
the dryer
13 side, and I probably should let David Allen
speak on that,
14 but my understanding is that you would be
drawing from a
15 storage that would not perhaps allow you to
export. Excuse
16 me, allow the Department to export.
17 MR. ALLEN:
That is a correct statement. The Ridenhour
18 Plan presents problems for exports in dryer year
types. But
19 let me that is fine.
20 MR. DODGE:
Peter Vorster has presented testimony that
21 the export issue is about 4 cfs or 3,000
acrefeet a year.
22 Do you disagree
with that?
23 MR.
KAVOUNAS: I have no opinion on that.
24 MR.
BIRMINGHAM: I am going to object on the ground it
25 is vague.
0209
01 Are you asking the
witness, Mr. Dodge, if he agrees
02 with Mr. Vorster's submitted testimony on that
subject or
03 are you asking him does he agree with the
testimony?
04 MR. DODGE:
The latter.
05 MR.
KAVOUNAS: Do I agree that Peter Vorster testified
06 to that?
07 MR. DODGE:
Mr. Vorster has made a calculation that
08 suggest that if you use the Ridenhour flows, as
opposed to
09 the DWP flows, that on average year DWP would be
allowed to
10 export about 3,000 acrefeet less than it
otherwise would
11 posttransition.
12 Do you have any
problems with Mr. Vorster's
13 calculations?
14 MR.
KAVOUNAS: I have no opinion on his calculations.
15 MR. DODGE:
Do you have any problem?
16 MR. ALLEN:
Let me kind of expand on that a little bit.
17 Peter Vorster did not present any testimony
regarding
18 reduction of flows. However, he did
perform on his own some
19 calculations in which the median he showed
that the
20 median reduction would be approximately 3,000
acrefeet.
21 Let me keep in mind that the median tends to
actually
22 underestimate the average because of the actual
distribution
23 of data.
24 MR. DODGE:
Do you have any problem with his
25 calculations as to what the median figure
is?
0210
01 MR. ALLEN: I
cannot ascertain whether or not his
02 numbers are adequate because I did not review
his
03 calculations.
04 MR. DODGE:
Mr. Kavounas, hypothetically, if the Water
05 Board were to reduce the base flows in the four
tributary
06 streams, have you made any calculation as to
whether the
07 median loss of 3,000 acrefeet could be made up
such that
08 you could have the Ridenhour maintenance flows
and reduced
09 base flows with the same export?
10 MR.
KAVOUNAS: I have not done any such
calculation.
11 That would not be within my scope of work.
12 MR. DODGE:
If that were possible, then the objection
13 to the Ridenhour flows as they reduced exports
would be
14 solved, couldn't it?
15 MR.
KAVOUNAS: I'd have to think about that.
16 MR. DODGE:
Read you from the scientists' October 1995
17 restoration proposal, Page 140:
18
If flows necessary for the stream to maintain
19
itself are not provided, a different plan
20
than the one proposed must be prepared.
21
Alternative recommendations would identify
22
actions needed to create and maintain the
23
stream habitat in lieu of natural processes
24
doing so. These alternative recommendations
25
would necessarily include constructing bars
0211
01
and pools, removing accumulated fines from
02
spawnable gravels, and mechanically control
03
encroaching vegetation. Indefinite
04
maintenance would be required as identified
05
in a rigorous monitoring program. (Reading.)
06 Do you recall that
language?
07 MR.
KAVOUNAS: It sounds familiar.
08 MR. DODGE:
Did Los Angeles prepare such a different
09 plan as the Ridenhour memo states.
10 MR.
KAVOUNAS: No.
11 MR. DODGE:
Do you have any ideas, as you sit here
12 today, what the cost of such a plan would be?
13 MR.
KAVOUNAS: No, I do not.
14 MR. DODGE:
Based on your experience under the RTC, it
15 could be quite expensive, couldn't it?
16 MR.
KAVOUNAS: I am sorry, with all due respect, I have
17 no experience with the RTC. I came on
board 13 months ago.
18 MR. DODGE:
Have you reviewed Los Angeles' experience
19 with the RTC?
20 MR.
KAVOUNAS: No, I have not.
21 MR. DODGE:
Dr. Platts, based on the experience with
22 the RTC, such a handson restoration program
can be
23 expensive, can't it?
24 MR.
BIRMINGHAM: We will stipulate that the Department
25 of Water and Power spent millions of dollars in
restoring
0212
01 Lee Vining Creek under the auspices of the RTC,
which have
02 now flushed out into Mono Lake as a result of
high floods.
03 MR. DODGE:
You objected to speeches, and you make
04 one.
05 MR.
BIRMINGHAM: You are asking questions, and I am
06 stipulating to fact.
07 MR. DODGE:
Yeah, yeah. Right.
08 CHAIRMAN
CAFFREY: Gentlemen, let's proceed.
09 MR. DODGE:
Let me ask you to turn to Page 5 of your
10 testimony, Mr. Kavounas.
11 See the item on
fish passage there?
12 MR.
KAVOUNAS: Item 8.a.7. Yes, I do.
13 MR. DODGE:
Do you propose no fish passage on Parker
14 and Walker Creek? Correct?
15 MR.
KAVOUNAS: That is correct.
16 MR. DODGE: Reading to you from Page 45 of
D1631,
17 Item 1:
18
A fish and sediment bypass system should be
19
constructed around the Walker Creek diversion
20
facility.
(Reading.)
21 Do you recall that
language?
22 MR.
KAVOUNAS: Yes.
23 MR. DODGE:
How do you reconcile your failure to have a
24 fish passage provision with that language?
25 MR.
KAVOUNAS: Well, Page 204, order of the
decision,
0213
01 says:
02
The Stream Restoration Plan shall make
03
recommendations on stream and stream channel
04
restoration, including but not limited to the
05
following.
(Reading.)
06 Item 7 is
construction of fish and sediment bypass
07 system.
08 MR. DODGE:
You would agree with me that the language
09 on Page 45 is pretty unambiguous?
10 MR.
KAVOUNAS: Yes.
11 MR. DODGE:
Reading again on Lee Vining Creek
from
12 D1631.
13
A sediment bypass system should be
14
constructed at the Lee Vining Creek
15
diversion.
(Reading.)
16 Do you see that,
sir?
17 MR.
KAVOUNAS: Excuse me, what page are you on?
18 MR. DODGE:
Thirtyseven.
19 MR.
KAVOUNAS: Right.
20 MR. DODGE:
You don't propose to construct anything at
21 Lee Vining, do you?
22 MR.
KAVOUNAS: That's correct.
23 MR. DODGE:
Do you recall that the Ridenhour Plan
24 makes a suggestion as to how to accomplish
sediment bypass?
25 MR.
KAVOUNAS: I don't at this time.
0214
01 MR. DODGE:
Take a look at Pages 200 to 202 of the
02 Ridenhour Plan, if you will, please.
03 MR.
KAVOUNAS: Page 201, Paragraph A:
04
Construction of a bypass to the left of Lee
05
Vining conduit diversion should be
06
practicable.
(Reading.)
07 MR.
DODGE: Referring to LV5 on Page 200 and
then W4
08 on Page 201 and P4 on Page 202.
09 MR.
KAVOUNAS: Okay. I am there.
10 MR. DODGE:
Those are recommendations that talk
11 conceptually how you might accomplish sediment
and fishing
12 bypass, correct?
13 MR.
KAVOUNAS: Correct.
14 MR. DODGE:
Did Los Angeles hire someone to make an
15 analysis of this?
16 MR.
KAVOUNAS: No, we did not. Because in the
draft
17 plan that the Department issued on or around
November 1, of
18 1995, the proposal for sediment passage was that
we would
19 engage in a two year study. At the TAG
meeting we had in
20 Lake Tahoe, the parties seemed to it seemed
to me,
21 anyway, that the parties over there were calling
for more
22 action than that. From January 9th, when
we had that TAG
23 meeting, to the time that we had to publish a
plan, it was
24 not a whole lot of time.
25 So, we presented
some action after consulting with Dr.
0215
01 Beschta. We presented a plan that would
provide some
02 sediment passage. In my opinion, a
sediment bypass system
03 is not necessarily a facility, doesn't have to
be the most
04 expensive way. And from geomorphic
perspective, if you are
05 providing the sediments downstream, it doesn't
matter how
06 they are going to pass the facility.
07 MR. DODGE:
D1631 came down when? I can't remember.
08 BOARD MEMBER DEL
PIERO: October
09 MR.
KAVOUNAS: September 28, 1994.
10 MR. DODGE:
September of 1994. As early as as late
11 as early 1996, 15 months later, your proposal
for sediment
12 bypass was to study it, correct?
13 MR.
KAVOUNAS: Correct.
14 MR. DODGE:
You didn't study it during that 15 months?
15 MR.
KAVOUNAS: That's correct.
16 MR. DODGE:
Mr. Tillemans, Page 5 of your testimony
17 talks about Parker plug. You see that
testimony?
18 MR.
TILLEMANS: Yes.
19 MR. DODGE:
You talk about the Parker plug being a
20 longterm source of gravels and fines for lower
Rush Creek.
21 Does the Parker
plug really provide fines? Is that
22 your testimony?
23 MR.
BIRMINGHAM: I object to the question on the
24 grounds it is argument. The testimony is
the testimony. If
25 Mr. Dodge doesn't agree with it, he doesn't
agree with it.
0216
01 That's an argumentative question.
02 MR. DODGE:
What is the basis of your testimony?
03 MR.
TILLEMANS: My testimony?
04 MR. DODGE:
Yes.
05 MR.
TILLEMANS: In discussions with consultants.
06 MR. DODGE:
Whom?
07 MR.
TILLEMANS: Dr. Beschta. I do believe it
provides
08 source of fines and gravels that are present
there.
09 MR. DODGE: I
will get to gravels in a second.
10 Dr. Beschta, do
you believe that Parker plug is a
11 source of fines?
12 DR. BESCHTA:
There is an erosion along the toe slopes
13 of the channel up there, so there are fines
coming in on the
14 channel.
15 MR. DODGE:
Be pretty insignificant, wouldn't it?
16 DR. BESCHTA:
I am not claiming I've never claimed
17 that it was large, but there certainly are fines
coming into
18 the system.
19 MR. DODGE:
You will also say, Mr. Tillemans, it is a
20 source of gravel. But the Rush Creek below
the Parker plug
21 doesn't lack for gravel, does it?
22 MR.
TILLEMANS: I don't know any places that makes
23 gravel.
24 MR. DODGE:
Mr. Kavounas, is Los Angeles' Stream and
25 Channel Restoration Plan still Exhibit 16?
Have there been
0217
01 any changes?
02 MR.
KAVOUNAS: Not that I know of.
03 MR. DODGE:
We have had Dr. Beschta and Dr. Kauffman
04 come and critique the plan and that is
fine. That testimony
05 has not changed the plan, has it?
06 MR.
KAVOUNAS: It is my understanding that Dr. Beschta
07 and Dr. Kauffman's critique was a positive one
for the
08 Department's plan and, no, I guess we didn't
change the
09 plans as a result of that.
10 MR. DODGE:
Mr. Tillemans, you showed us a bunch of
11 photos several hours ago of developing riparian
vegetation.
12 Would you you agree with me that a lot of that
growth
13 resulted from reopening of channels and in a
raised water
14 table?
15 MR.
TILLEMANS: I cannot positively agree upon that
16 because I don't have all the water table data to
conclude
17 that.
18 MR. DODGE:
Would that be your best guess?
19 MR.
TILLEMANS: I would say when I look upon streams,
20 I don't look upon it as one thing or one
event. I look at
21 upon it as a continuum of flows and a process
that occurs to
22 not only in a certain reach but is influenced by
what
23 happens above it.
24 MR. DODGE:
Would you agree that the vegetation that
25 you showed us pictures was aided by the very
high flows in
0218
01 1995 and 1996?
02 MR.
TILLEMANS: I think the majority of the vegetation
03 on the floodplains in those creeks were aided by
the flows
04 we have recently seen.
05 MR. DODGE:
What was the high flow in Rush Creek in
06 1995?
07 MR. TILLEMANS: I
would have to defer that question.
08 MR.
ALLEN: The peak flow of 1995 on Lower Rush
Creek
09 was 635 cfs.
10 MR. DODGE:
635 cfs?
11 MR. ALLEN:
Yes.
12 MR. DODGE:
At least in 1995 Rush Creek was
13 experiencing 635 cfs, and that was positive,
right, Mr.
14 Tillemans?
15 MR.
TILLEMANS: Yes.
16 MR. DODGE:
Los Angeles' plan doesn't propose to
17 release as much as 635 for maintenance flows,
does it?
18 MR. ALLEN: I
think the plan proposes to release 500
19 as a minimum in extremely wet year types.
20 MR. DODGE:
Could be more, right?
21 MR. ALLEN:
Yes, it could be.
22 MR. DODGE:
It could be just 500?
23 MR. ALLEN:
That would depend on hydrologic conditions.
24 MR. DODGE:
It could be as low as 500?
25 MR. ALLEN:
As a minimum in extreme years.
0219
01 MR. DODGE:
Mr. Tillemans, your testimony speaks on
02 vegetation that has been slow to respond and
planting in
03 those areas.
04 Do you recall that
testimony?
05 MR.
TILLEMANS: Yes, I do.
06 MR. DODGE:
Do you have a map or something that tells
07 us exactly what those areas are?
08 MR.
TILLEMANS: I described them in my testimony, but
09 I don't have a map that shows those areas
exactly. I can
10 look at my testimony and discuss it.
11 MR. DODGE:
Is there a plan to create a specific
12 proposal of where you are going to plant
vegetation?
13 MR.
TILLEMANS: Yes, there is.
14 MR. DODGE:
The question, sir, on the interfluves; do
15 you have specific areas and acreages identified
for planting
16 on the interfluves?
17 MR.
TILLEMANS: Can I have some time to look up that
18 section.
19 MR. DODGE:
Does it identify the specific areas on the
20 interfluves that you are going plant and the
types of
21 vegetation that you are going to plant?
22 MR.
TILLEMANS: Not specifically, no. It does
state
23 addresses the interfluves areas, though.
24 MR. DODGE:
Presumably, in future there will be some
25 process to determine what areas are going to be
planted and
0220
01 what species?
02 MR.
TILLEMANS: It says areas, and it is specific to
03 creeks. It says areas targeted for
planting will be
04 suitable for regeneration based on Jeffrey pine
species
05 requirements, and LADWP proposes to plant
Jeffrey pines in
06 interfluves areas that are currently lacking big
wood.
07 MR. DODGE:
Let me see if I can cut to the chase.
08 Would you contemplate that the identification of
specific
09 areas to plant, either areas that are slow to
recover or
10 areas on the interfluves, the identification of
what areas
11 to plant or which species would be a joint
process in which
12 all the parties participated?
13 MR.
TILLEMANS: I guess that would be based upon legal
14 requirement and what we are obligated to do
under the
15 decision.
16 MR. DODGE:
Now, you're proposing in your plan, Mr.
17 Tillemans, to reopen certain Rush Creek
channels, correct?
18 MR.
TILLEMANS: That's correct.
19 MR. DODGE:
That is as described in Exhibit 16,
20 correct?
21 MR.
TILLEMANS: That's correct.
22 MR. DODGE:
Now, let me follow up on a line of
23 questions that Mr. RoosCollins asked
you. Let's take 1938,
24 which I will warrant to you is a very high flow
year.
25 Okay. And 1996 or 1995, also high flow
years. Okay.
0221
01 Now, would you
agree with me that compared to the
02 reasonably unperturbed stream condition in 1938,
and I will
03 ask you to assume it was reasonably unperturbed,
that in
04 1995 and 1996 there is a lot of debris going
down the
05 channels at high flows?
06 MR.
TILLEMANS: In which year?
07 MR. DODGE:
In 1996. A lot more debris than in the
08 natural condition.
09 MR.
TILLEMANS: How much debris goes down in the
10 natural condition?
11 MR. DODGE: I
am asking you to compare the two. In one
12 you have a reasonably natural stream channel
with riparian
13 vegetation on the banks, as compared to the
present
14 situation. Okay.
15 MR.
BIRMINGHAM: I am going to object to the
question
16 on the grounds it is vague as the point.
Mr. Dodge asked,
17 told, Mr. Tillemans to compare 1938 to 1995 and
then said
18 unperturbed condition. I think Decision
1631 establishes in
19 1938, Rush Creek was extremely an perturbed,
degraded
20 system.
21 MR. DODGE:
There was specific evidence, Mr. Chairman,
22 that high flows came down Rush Creek in 1938 and
didn't have
23 much of an adverse affect at all because the
vegetation was
24 holding the stream together. You heard
about that at
25 length.
0222
01 CHAIRMAN
CAFFREY: Who is the question directed to?
02 MR. DODGE:
Mr. Tillemans.
03 CHAIRMAN
CAFFREY: Mr. Tillemans. Mr. Tillemans, do
04 you feel qualified to answer the question?
05 MR.
TILLEMANS: Are you finished with your
question? I
06 need to
07 CHAIRMAN
CAFFREY: You need to restate the question
08 more succinctly.
09 MR. DODGE:
Dr. Trush
10 CHAIRMAN
CAFFREY: That is succinct.
11 MR. DODGE:
Assume that in 1938 the vegetation was in
12 good condition on Rush Creek and very high flows
came down
13 without causing any significant problem.
14 Can you make that
assumption with me? Would you agree
15 that the same flows today, 19951996, existing
conditions, a
16 lot more debris would come down that creek than
happened in
17 1938?
18 DR. TRUSH:
No. I have nothing to go on there. You
19 can tell by an aerial photo, maybe not a lot
happened on the
20 plan form of the river. You didn't see
major blow out
21 area. All you need is twofoot cut on the
outside bank and
22 trees drop in. There you would have large
trees dropping in
23 that would have a single much larger effect than
a whole
24 pile of smaller stuff coming in in this past
year. So,
25 really, I can pretend, but I can't even do that.
0223
01 MR. DODGE:
You don't know? You don't have to answer a
02 question you don't know the answer to.
03 DR. TRUSH:
No, can't answer.
04 MR. DODGE: I
heard you testify, Mr. Tillemans, about
05 the values of the A1 channel in Lee Vining
Creek.
06 Do you recall that
testimony?
07 MR.
TILLEMANS: I think what I was I recall
the
08 testimony.
09 MR. DODGE:
You did testify about the values of A1
10 channel, correct?
11 MR.
TILLEMANS: I testified to what was occurring
12 within the vicinity of the A1 channel.
13 MR. DODGE:
Do you think rewatering of the A1 channel
14 was a valuable thing for Lee Vining Creek?
15 MR.
TILLEMANS: Based on what I know from past, that
16 channel was already starting to rewater itself
on its own,
17 and it was an addition. Most of the
rewatering was an
18 addition, an augmentation of water that was
already starting
19 to appear.
20 MR DODGE:
Dr. Beschta, just a few questions for you.
21 Assuming you're
standing at the Narrows, looking down
22 Rush Creek.
23 DR. BESCHTA:
Okay.
24 MR. DODGE:
On the lefthand side of the stream there
25 is what has been referred to as the Vestal
springs. Are you
0224
01 aware of that?
02 DR. BESCHTA:
I am aware of the springs and maybe the
03 attachment of vestals. I wasn't sure that
that was the
04 exact place.
05 MR. DODGE: I
think they are named after Elden Vestal
06 who testified at great length about that.
07 DR. BESCHTA:
Okay.
08 MR. DODGE:
Mr. Vestal testified about how the springs
09 enhance the fishery. Are you aware of
that?
10 DR. BESCHTA:
Yes, I am.
11 MR. DODGE:
Would you agree with me that the source of
12 those springs had nothing to do with Rush Creek,
but rather
13 came from water that flowed down Parker and
Walker Creeks?
14 DR. BESCHTA:
In my mind, I don't know where the water
15 from the springs is coming from. I haven't
studied that.
16 MR. DODGE:
Assume, if you will, the water from the
17 springs comes from Parker and Walker Creek and
percolation
18 from the distributaries of Parker and
Walker. Can you
19 assume that for me?
20 DR.
BESCHTA: As an assumption, sure.
21 MR.
DODGE: Let's take a look at your testimony at
22 Page 16. I am going to read you a portion
of it.
23
The concept of "irrigating the bottomland" in
24
attempts to recreate springs on the
25
bottomland is not a credible restoration
0225
01
practice.
(Reading.)
02 Do you see that,
sir?
03 DR. BESCHTA:
That was a misreading. The concept of
04 irrigating the uplands.
05 MR. DODGE:
Irrigating the uplands?
06 DR. BESCHTA:
Yes.
07 MR. DODGE:
Now, hypothetically, if rewatering the
08 distributaries of Parker and Walker Creek that
existed
09 naturally before diversions would recreate
spring flows that
10 benefited the fishery, would you regard that as
"credible
11 restoration practice"?
12 DR. BESCHTA:
Rewater they are watered now, so I am
13 not sure what the rewatering is doing.
There is water in
14 Parker/Walker.
15 MR. DODGE:
Assuming that rewatering the distributaries
16 will add to the water in the springs, would you
regard that
17 as a credible restoration practice?
18 DR. BESCHTA:
I guess if it could be shown that on the
19 alluvial features up there that that stream
normally had
20 distributaries and that water was spread out
there naturally
21 and that water was connected to the springs, you
make all
22 those ifs ands or buts, then maybe putting more
water on the
23 alluvial fan would be a connection to the
springs. I can't
24 make that connection.
25 MR. DODGE:
Hypothetically, it would be a credible
0226
01 restoration practice?
02 DR. BESCHTA:
If your goal was to rewater the springs
03 and bring them up to some level that you
perceived was there
04 prior. Whether that relates to the
fisheries is a different
05 question.
06 MR.
KAVOUNAS: Can I add to that answer, Mr.
Dodge?
07 MR. DODGE:
Mr. Birmingham will ask you questions on
08 crossexamination. I have my time.
09 MR.
KAVOUNAS: Please excuse me.
10 MR. DODGE:
Page 3, Dr. Beschta.
11 DR. BESCHTA:
Where?
12 MR. DODGE:
Your testimony, stream restoration.
13 DR. BESCHTA:
Okay.
14 MR. DODGE:
You say under L.A.'s channel maintenance
15 flows, proposed peak flows for Rush Creek will
be "slightly
16 greater than the historical impaired
flows."
17 Do you see that,
sir?
18 DR. BESCHTA:
I don't see that, but it sounds like it
19 should be there.
20 MR. DODGE:
It is right here.
21 DR. BESCHTA:
Okay.
22 MR. DODGE:
Do you see that.
23 DR. BESCHTA:
Got it.
24 MR. DODGE:
That is your testimony?
25 DR. BESCHTA:
Yes.
0227
01 MR. DODGE:
You testified this morning about Table 2,
02 and I think you inadvertently referred to
unimpaired flows.
03 You meant impaired flows, didn't you?
04 DR. BESCHTA:
I may have gotten that mixed around. I
05 apologize if I did. I am working with
impaired flows, yes.
06 MR. DODGE:
Would you agree with me that the
07 prediversion streams were, if you will, formed
by the
08 unimpaired flows?
09 DR. BESCHTA:
Prior to Cal Edison, yes.
10 MR. DODGE:
It would be desirable, wouldn't it, to
11 deliver the unimpaired flows to Rush Creek,
wouldn't it?
12 DR. BESCHTA:
The easiest way to get unimpaired flows
13 would be to have Cal Edison change their
policies.
14 MR. DODGE:
Are you aware that the three scientists in
15 their October 1995 recommendations based their
maintenance
16 flows on unimpaired flows, correct?
17 DR. BESCHTA:
I understand they considered that, yes,
18 in their decision, but I was not part of their
decision, so
19 I really don't know what or how they got there.
20 MR. DODGE:
Now, you say that you refer to slightly
21 greater than historical impaired flows.
But if you look at
22 Table 2, Dr. Beschta, you would agree with me,
wouldn't you,
23 that DWP in dry, drynormal and extreme wet
provides
24 substantially less than the historical impaired
flows?
25 DR. BESCHTA:
Less, yes.
0228
01 CHAIRMAN
CAFFREY: Mr. Dodge, since you are between
02 questions I will interrupt you now. There
is about 20
03 seconds left. How much more time? I
should say you are
04 within 20 seconds of crossexamining for an
hour. How much
05 time more do you think you are going to need?
06 MR. DODGE: I
would certainly hope to finish within
07 half an hour.
08 CHAIRMAN
CAFFREY: Another half hour. Then why don't
09 we it is pretty close to 4:30. Maybe
we just break now,
10 or do you want to go for about seven or eight
minutes and
11 then we will come back? I don't want to
get overly precise
12 here.
13 MR. DODGE:
Let me see if I can finish with Dr.
14 Beschta.
15 CHAIRMAN
CAFFREY: In about, say, six or seven minutes?
16 MR. DODGE: I
hope so.
17 CHAIRMAN
CAFFREY: All right, sir.
18 DR. BESCHTA:
He told Bill Platts he only had one
19 left.
20 MR. DODGE:
Page 7 of your testimony, sir?
21 DR. BESCHTA:
Yes.
22 MR. DODGE:
You say that the difference between a peak
23 flow of 500 cfs and 600 cfs in extreme year type
would
24 result in imperceptible differences in the Rush
Creek
25 channel.
0229
01 Do up see that,
sir?
02 DR BESCHTA:
Yes, I do; it's right at the top.
03 MR. DODGE:
Can you really testify to that with any
04 certainty?
05 DR. BESCHTA:
You have to keep in mind in the context
06 of which I did the flow evaluation. I was
looking at this
07 flow distribution, and the extreme wet occurs
less than or
08 approximately eight percent of the time.
And if we have all
09 the rest of the these flows occurring, as they
are projected
10 to occur, and then during that one eight percent
of the
11 time, we either have a 500 cfs or a 600 cfs
event, I would
12 suggest that it may well be indetectable over
the scheme of
13 things.
14 MR. DODGE:
It may well be detectable, too?
15 DR. BESCHTA:
That is a possibility. Hopefully, that
16 is what the Monitoring Plan would show.
17 MR. DODGE:
Doesn't it make sense to you, sir, that at
18 600 cfs larger rocks are going to move than at
500 cfs?
19 DR. BESCHTA:
Sure.
20 MR. DODGE:
Isn't it also true that 600 cfs is going to
21 raise the water table higher than at 500
cfs?
22 DR. BESCHTA:
Yes.
23 MR. DODGE:
And you would think it was a good idea to
24 monitor these sorts of things and make a
determination,
25 correct?
0230
01 DR. BESCHTA:
I think monitoring the flows and
02 monitoring what happens in that system is
incredibly
03 important, yes.
04 MR. DODGE:
Do you think sufficient monitoring has been
05 done to make determinations as to which flows
should be?
06 DR. BESCHTA:
Not at this point. Monitoring has not
07 initiated.
08 MR. DODGE:
Did you hear Mr. Platts' testimony on
09 sediment bypass when I asked him those
questions?
10 DR. BESCHTA:
I was listening.
11 MR. DODGE:
Do you basically agree with Dr. Platts?
12 DR. BESCHTA:
I am not sure what part you want to
13 agree. You had quite a discussion going.
14 MR. DODGE:
Anything that he said about sediment bypass
15 that you disagree with?
16 DR. BESCHTA:
I think both I shouldn't speak for
17 Bill. I am certainly in favor of
physically bypassing or
18 getting sediment past that system. In
fact, maybe I was the
19 first one to introduce the topic to the whole
discussion
20 here a long time ago.
21 BOARD MEMBER
STUBCHAER: You were.
22 DR. BESCHTA:
How you exactly do that is another
23 question, whether you reconstruct those channels
or whether
24 you do something else, I guess, is a question.
25 MR. DODGE:
If I may look at my notes for a second, I
0231
01 may be just about finished with Dr. Beschta.
02 CHAIRMAN
CAFFREY: All right, Mr. Dodge.
03 MR. DODGE:
This will be a good time too break.
04 CHAIRMAN
CAFFREY: Thank you. Let me just say before
05 we do that, assume that you will need a half
hour, Mr.
06 Dodge, when we come back at 5:00. We will
give you another
07 half hour for crossexamination. Then we
will have
08 crossexamination from Ms. Cahill and Ms.
Scoonover.
09 Then we still have
to hear direct from the waterfowl
10 panel. And then or now, before we get to
that, there is a
11 possibility of redirect and recross and then we
go to the
12 waterfowl panel.
13 BOARD MEMBER DEL
PIERO: No possibility.
14 CHAIRMAN
CAFFREY: Anybody planning on getting home in
15 time for the 7:30 version of Seinfeld is
probably not going
16 to, likely.
17 MR.
BIRMINGHAM: Mr. Chairman, you commented earlier on
18 the importance of crossexamination, how you
recognized that
19 it is related to the right of due process.
I would like to
20 observe in hearings that I have appeared before
Mr.
21 Stubchaer and Mr. Del Piero, they had no problem
cutting
22 people off on crossexamination.
23 CHAIRMAN
CAFFREY: May be a sweeter guy than I am.
24 BOARD MEMBER DEL
PIERO: We all know that, Mr.
25 Chairman.
0232
01 CHAIRMAN
CAFFREY: Let's be back at close to 5:00 as we
02 can. Then we can resume.

03 CHAIRMAN
CAFFREY: Mr. Dodge, would you like to resume
04 your crossexamination of the three
panels? We will give
05 you up to half an hour. Hopefully, you can
be more brief
06 than that, in the interest of just moving this
thing along.
07 MR. DODGE: I
will try to be to the point and get
08 there as soon as I can.
09 CHAIRMAN
CAFFREY: We thank you for that, sir. Please
10 proceed.
11 MR. DODGE:
Mr. Allen, your planning for Rush Creek
12 high flows includes restoring to the return
ditch to 350
13 cfs, correct?
14 MR. ALLEN:
That is correct.
15 MR. DODGE:
Do you have a cost on that?
16 MR.
ALLEN: That, I believe, that cost is in
the
17 Stream Restoration Plan. I don't know the
exact numbers of
18 that.
19 MR. DODGE:
Your plan calls for fish habitat at all
20 flows up to 350 cfs?
21 MR. ALLEN:
Are you referring to the stream plan or the
22 Grant Lake Management Plan?
23 MR. DODGE: I
am referring to your plan to upgrade the
24 Mono Basin Return Ditch to 350 cfs. Does
your plan provide
25 for fish habitat at all flows up to 350 cfs?
0234
01 MR. ALLEN:
To my knowledge, the design plans for
02 rehabilitating the ditch have not been finalized
or
03 completed, so I cannot answer that question.
04 MR. DODGE:
Do you think it might be reasonably
05 expensive to design a ditch that had fish
habitat at flows
06 up to 350 cfs?
07 MR. ALLEN: I
really can't testify to the variables
08 that would be required to provide fish habitat
in such a
09 design.
10 MR. DODGE:
But if, hypothetically, you were to bypass
11 Grant Lake by a tunnel that carried 600 cfs, you
wouldn't
12 have to have a return ditch at all, would you?
13 MR. ALLEN:
Theoretically, if such an episode was
14 available, yes.
15 MR. DODGE:
The 350 cfs that you propose in the return
16 ditch will not, by itself, provide either the
scientists'
17 maintenance flows or DWP's maintenance flows in
a lot of
18 year types; isn't that correct?
19 MR. ALLEN:
That is correct.
20 MR. DODGE:
You propose to deal with that by Lee Vining
21 Creek augmentation, correct?
22 MR. ALLEN:
Yes. The diversions from Lee Vining Creek
23 would augment channel maintenance flows.
24 MR. DODGE:
As I understand your proposal, you propose
25 to augment with Lee Vining Creek water up to 150
cfs,
0235
01 correct?
02 MR. ALLEN:
That would depend on the year type. So it
03 would be up to 350 for an extremely wet year.
04 MR. DODGE:
But as your testimony recognizes, even with
05 the Lee Vining Creek augmentation, you would not
reliably
06 provide the scientists' recommended maintenance
flows in
07 Rush Creek in extreme years?
08 MR. ALLEN:
You are referring to the Ridenhour
09 MR. DODGE:
Yes, sir.
10 MR. ALLEN:
Yes.
11 MR. DODGE:
That is correct?
12 MR. ALLEN:
On a reliable basis, no. But if you look
13 at historical records you will see that in three
or four
14 past extremely wet years, flows were in excess
of would
15 have been excess of 600 cfs.
16 MR. DODGE:
So, sometimes it will happen and sometimes
17 it won't?
18 MR. ALLEN:
That is correct.
19 MR. DODGE:
Your testimony at Page 6 talks about the
20 Ridenhour flows, and you rejected them in part
because of
21 what you call capacity limitations, correct?
22 MR. ALLEN:
This is correct.
23 MR. DODGE:
Buy capacity limitations, I take it you
24 mean that even with the return ditch carrying
350 cfs, there
25 is no reliable way to get 600 cfs down in wet
years,
0236
01 correct?
02 MR. ALLEN:
In the return ditch, no.
03 MR. DODGE:
Even with augmentation?
04 MR. ALLEN:
With augmentation spills and return ditch,
05 we can get flows that would be equivalent to two
of those
06 recommended in the Ridenhour work plan.
07 MR. DODGE:
But just so we are clear, if there is no
08 spill, then you cannot get at 600 cfs down
through the
09 combination of a return ditch and the
augmentation?
10 MR. ALLEN:
Without the spill, the flows in Rush Creek
11 would be 500 cfs.
12 MR. DODGE:
So, by capacity limitations, what you mean
13 is that, basically, you don't want to spend the
money to
14 create a tunnel that bypasses Grant Lake; is
that correct?
15 MR. ALLEN: I
did not make that decision, no. But
16 looking at given facilities and in the current
17 configuration, no, we cannot provide the flows
in the
18 Ridenhour work plan.
19 MR. DODGE:
But Grant Lake has a capacity for 47,000
20 acrefeet, correct?
21 MR. ALLEN:
Yes, that's correct.
22 MR. DODGE:
So, if you had a bypass facility, there
23 would be plenty of water to provide 600 cfs,
correct?
24 MR. ALLEN:
That would depend on previous hydrologic
25 conditions.
0237
01 MR. DODGE:
In an extreme year, which is what we are
02 talking about, there wouldn't be any problem
providing 600
03 cfs, would there?
04 MR. ALLEN:
No.
05 MR. DODGE:
Thank you.
06 Now, let's get to
this augmentation, up to 150 cfs.
07 Tell me what the criteria you propose for
augmentation.
08 MR. ALLEN:
Specifically which criteria are you
09 MR. DODGE:
We are in a year where you are going to
10 augment Rush Creek flows by 150 cfs through
using Lee Vining
11 Creek water.
12 How are you going
to decide when to deliver the Lee
13 Vining Creek water?
14 MR. ALLEN:
The first step in that process is the use
15 of regression equations which we would use to
estimate the
16 expected peak flow for Lee Vining Creek.
This would be
17 based on the forecasted runoff. And then,
from that, we
18 would use that information and monitor the flows
to get a
19 feel for when the actual peak passes. And
following that,
20 we would begin diversions for the Rush Creek
augmentation.
21 MR. DODGE:
You get a feel for when the peak passes; is
22 that your testimony?
23 MR. ALLEN:
Yes, that is correct. You can review
24 historic data for specific year types, and there
is
25 typically ranges of peak flows that correspond
directly for
0238
01 that year type. And using that
information, along with the
02 regression equations, you can get a very, very
good estimate
03 of the expected peak flows for that year.
04 MR. DODGE:
So you have on day one, you've established
05 the peak flows. When will you begin to
divert Lee Vining
06 Creek water?
07 MR. ALLEN:
The plan calls for diversions to begin
08 seven days after the peak flow.
09 MR. DODGE:
Seven days after the peak flow. Was that
10 done in 1996?
11 MR. ALLEN:
The 1996 operations were not the Lee
12 Vining Creek augmentations as proposed in the
Grant Lake
13 Management Plan.
14 MR. DODGE:
Augmentation didn't work in 1996, did it?
15 MR. ALLEN:
As I said, the basis for the Lee Vining
16 Creek augmentation is contingent upon three
things
17 happening. Number one, the return ditch
needs to be
18 rehabilitated. Number two, the control
gates at the end of
19 the conduit need to be repaired, and number
three, the
20 conveyance facility from the conduit to Rush
Creek needs
21 some work. And I believe that all three of
those aspects
22 were identified in the Stream Channel
Restoration Plan.
23 MR. DODGE:
So, you need some changes in the facility
24 before it is going to work?
25 MR. ALLEN:
That is correct.
0239
01 MR. DODGE:
Isn't it a fact, sir, in some years there
02 simply won't be 150 cfs of Lee Vining Creek
water available?
03 Isn't that possible?
04 MR. ALLEN:
Yes. That possibility came up in
05 discussions with the ad hoc flow committee.
06 MR. DODGE:
In fact, your recognized that at Page 98
07 of your GLOMP plan, don't you?
08 MR. ALLEN:
Yes, that is correct.
09 MR. DODGE:
Now, if you begin diverting Lee Vining
10 Creek water too early, that is you missed the
peak, then
11 this plan has the danger of, in effect, missing,
cutting off
12 the primary peak; isn't that correct?
13 MR. ALLEN:
That is correct. And I may add that
14 discussion came up in the ad hoc flow committee.
15 MR. DODGE:
And the Lee Vining Creek augmentation plan
16 also drastically reduces the declining peak on
Lee Vining
17 Creek, correct? As Lee Vining Creek comes
down from its
18 peak, you are going to be drastically reducing
that flow in
19 Lee Vining Creek?
20 MR. ALLEN:
Drastically is kind of a relative term. We
21 will ramp flows in accordance with
D1631.
22 MR. DODGE:
It's possible, isn't it, that when you
23 start to augment with Lee Vining Creek seven
days after when
24 you project its peak to be, it's possible that
you won't
25 have enough water in Lee Vining Creek both to
augment with
0240
01 150 cfs and to meet the Lee Vining Creek minimum
flows?
02 MR. ALLEN:
Could you repeat that question again?
03 MR. DODGE:
Is it possible, sir, based on your review
04 of the various years flows, is it possible that
you cannot
05 both augment Rush Creek flows with 150 cfs with
Lee Vining
06 Creek water and still meet the Lee Vining Creek
minimum
07 flows?
08 MR. ALLEN:
There is that extreme possibility.
09 However, the value for the 150 cfs diversion was
selected on
10 the basis that there would be sufficient water
above the
11 Decision 1631 minimum flows.
12 MR. DODGE:
If the Water Board, hypothetically, were
13 to accept your maintenance flow in Rush Creek of
500 cfs in
14 extreme years, is DWP prepared to have that as
part of a
15 license requirement?
16 MR. ALLEN: I
cannot answer that question.
17 MR. DODGE:
Mr. Kavounas.
18 MR.
BIRMINGHAM: I am not sure Mr. Kavounas is
19 qualified to answer that question.
20 CHAIRMAN
CAFFREY: Anyone qualified? Anyone on the
21 panel qualified?
22 MR.
KAVOUNAS: Can you repeat the question?
23 MR. DODGE:
If the Water Board were to accept your
24 channel maintenance flows in Rush Creek in
extreme years of
25 500 cfs, is DWP prepared to have that as part of
a Board
0241
01 order, a license requirement?
02 MR.
BIRMINGHAM: Mr. Dodge is asking this panel for
03 the position of the Department of Water and
Power, and no
04 one on this panel is in a position of the
Department of
05 Water and Power to make that kind of decision.
06 CHAIRMAN
CAFFREY: It is perfectly all right to answer
07 the question in that regard so that we don't
have to keep
08 interrupting you. If you don't feel
qualified enough
09 MR.
KAVOUNAS: My answer is, I couldn't answer it
10 without conference.
11 CHAIRMAN
CAFFREY: That is a perfectly acceptable
12 answer, sir. If that isn't clear to the
panelists, please
13 feel free. If you don't know or if you
don't feel empowered
14 by virtue of your position within the
organization, just say
15 so.
16 MR. DODGE: I
totally agree with that, Mr. Chairman.
17 But I would request that Mr. Birmingham not give
him the
18 answer. If he doesn't know the answer, he
can so state.
19 CHAIRMAN
CAFFREY: I think it is appropriate for
20 counsel to assist his witnesses. But your
concern is duly
21 noted.
22 Please proceed,
gentlemen.
23 MR. DODGE:
Mr. Allen, would you turn to Page 9 of
24 your testimony? Do you see Table B there,
sir?
25 MR. ALLEN:
Yes, I do.
0242
01 MR. DODGE:
You testified earlier to an effort to see
02 if you could induce spills in wet years.
03 Do you recall that
testimony?
04 MR. ALLEN:
That was correct.
05 MR. DODGE:
Does Table B relate to that effort?
06 MR. ALLEN:
Yes, it does.
07 MR. DODGE:
Now let me ask you, sir, you assume 35,000
08 acrefeet storage in Grant Lake on April 1,
correct?
09 MR. ALLEN:
That is correct.
10 MR. DODGE:
Am I right that you would be more likely
11 to have spills if you instead assumed 40,000
acrefeet in
12 Grant Lake Reservoir on April 1?
13 MR. ALLEN:
Given the conditions that this table was
14 developed under, which was the wet year types, I
don't it
15 is my judgment that the spills will occur
within a wet
16 year type you can force the reservoir to spill
at 35,000
17 acrefeet or from the 40,000 acrefeet.
18 MR. DODGE:
You could use 40,000 acrefeet, correct?
19 MR. ALLEN:
Yes, that is correct.
20 MR. DODGE:
That would make the spill more likely,
21 wouldn't it?
22 MR. ALLEN:
It wouldn't increase the probabilities that
23 significantly. If you look earlier in the
testimony, there
24 is actual percentages on how much water needs to
flow down
25 the creeks to fill, not only Grant Lake
Reservoir, but also
0243
01 the Southern Cal Edison reservoirs
upstream.
02 MR. DODGE:
Would having Grant Lake at 40,000 on April
03 1 increase the magnitude of the spill as
compared to 35,000?
04 MR. ALLEN: I
cannot answer because I did not do that
05 analysis.
06 MR. DODGE:
How about if we had Grant Lake at 45,000 on
07 April 1, would that increase either the
likelihood or
08 magnitude of spills?
09 MR. ALLEN:
Once again, I cannot answer that question.
10 MR. DODGE:
Turn, if you would, to Page 11 of your
11 testimony, sir. At the bottom of Page 11,
you do not follow
12 the scientists' maintenance flows for dry,
drynormal, and
13 the lower interval of normal years, correct?
14 MR. ALLEN:
That is correct.
15 MR. DODGE:
The reason for that, as you state, is
16 concern over export, correct?
17 MR. ALLEN:
That is one of the concerns. The other
18 concern is, as I stated in my direct testimony,
that the
19 Grant Lake Management Plan attempts to balance
all the
20 leases to Mono Lake and export with the
available runoff.
21 MR. DODGE:
You didn't have any restoration oriented
22 reason for rejecting the scientists' flows in
those years;
23 isn't that correct?
24 MR. ALLEN:
No, I did not.
25 MR. DODGE:
Final questions for you, sir.
0244
01 Los Angeles's
proposal does not provide posttransition
02 flows, correct?
03 MR. ALLEN:
That is correct.
04 MR. DODGE:
By posttransition I mean after Mono Lake
05 reached its transition level.
06 MR. ALLEN:
After it reaches the target elevation.
07 MR. DODGE:
Is there anything in D1631, any language
08 in D1631, that Los Angeles relies on in not
posing a
09 posttransition flow, to your knowledge?
10 MR. ALLEN:
Could you repeat the question?
11 MR. DODGE: I
mean, I've read D1631 and it looks to me
12 like you're supposed to provide a GLOMP,
period. You
13 provided one that doesn't have posttransition
flows. I am
14 wondering whether there is any analysis, that
you are aware
15 of, as to why that was done.
16 MR. ALLEN:
There was no analysis for what?
17 MR. DODGE:
As to why no posttransition flows are
18 proposed.
19 MR. ALLEN:
Because there are several factors involved
20 with that. The first was the condition of
the streams. The
21 second factor, and probably the most important
factor, is
22 that as the lake level reaches 6392, LADWP
export criteria
23 change significantly. And given the
situation that we are
24 in today, which is commonly referred to as the
transition
25 period, there are different water allocations
for the
0245
01 transition period versus the posttransition
period.
02 So, the actual
Grant Lake Management Plan provides a
03 mechanism to develop this posttransition plan,
if you will,
04 after the Mono Lake level reaches a specified
level.
05 MR. DODGE:
Dr. Kauffman, do you have your testimony
06 available?
07 DR.
KAUFFMAN: Yes, sir.
08 MR. DODGE:
On Page 2 of your testimony, you
say:
09
Ecological restoration attempts to return
10
riparian/streams zones as closely as possible
11
to predisturbance condition. (Reading.)
12 Do you see that,
sir?
13 DR.
KAUFFMAN: What paragraph?
14 MR. DODGE:
Page 2, the first full second full
15 paragraph under ecological restoration, third
sentence.
16 DR.
KAUFFMAN: Yes.
17 MR. DODGE:
Would you agree with me that if you were
18 trying to apply ecological restoration, as you
have defined
19 it, that you'd mimic the natural flows that
formed the
20 channels?
21 DR.
KAUFFMAN: Yes.
22 MR. DODGE:
Those would be the unimpaired flows?
23 DR.
KAUFFMAN: Yes.
24 MR. DODGE:
Are you aware that the stream scientists'
25 plan attempts had to do that?
0246
01 DR.
KAUFFMAN: No I don't have any knowledge of
02 that, sir.
03 MR. DODGE:
Page 9 of your testimony, sir, the
first
04 full paragraph toward the bottom:
05
Expansion of the area occupied by riparian
06
vegetation could most effectively be
07
accomplished through the continued rewatering
08
of secondary channels, backwaters, and
09
depressions via water release and limited
10
reopening of channels and a diligent
11
moratorium on livestock grazing, including
12
trespass livestock on Parker and Walker
13
Creek.
(Reading.)
14 Do you see that,
sir?
15 DR.
KAUFFMAN: Yes.
16 MR. DODGE:
Again, would that best be accomplished by
17 the high natural flows unimpeded by the
reservoirs?
18 DR.
KAUFFMAN: Yes. The secondary channel in the
one
19 season clearly are flowing during the peak
flows, and what
20 levels of peak flows they do flow, I don't know
if the data
21 exists.
22 MR. DODGE:
Let me turn quickly to Page 3 of your
23 testimony, down, the last full paragraph,
sir. I will read
24 you the part I am interested in.
25
High flows are needed to create these
0247
01
conditions. Seed dispersal and germination
02
are tied to coincide with late spring flows
03
when water tables are high and fresh alluvium
04
has been deposited.
(Reading.)
05 Do you see that,
sir?
06 DR.
KAUFFMAN: Yes.
07 MR. DODGE:
As I understand that testimony, you were
08 recommending coincidence in time of seed
dispersal and high
09 flows, correct?
10 DR.
KAUFFMAN: That is how most of this vegetation has
11 evolved. Typically you will see seed
dispersal in June,
12 late May, through the month of June, when
natural peak flows
13 did occur, and that is the mechanism of
dispersal of these
14 plants.
15 MR. DODGE:
How close in time of coincidence are you
16 looking for?
17 DR.
KAUFFMAN: Well, the period of time of which
18 seed dispersal occurs over a two to
threeweek period,
19 late in the spring, late May through June, and
that is when,
20 historically, one would have seen peak flows in
these
21 areas.
22 MR. DODGE:
If the peak flow in a regulated stream, if
23 the peak flow came three weeks after the
national peak flow,
24 would that create a problem?
25 DR.
KAUFFMAN: Yes, it would. It most likely
would.
0248
01 MR. DODGE:
If DWP's augmentation proposal for Lee
02 Vining Creek, if it brought on the peak flows to
Rush Creek
03 three weeks later than normally would happen,
that would be
04 a problem, wouldn't it?
05 DR.
KAUFFMAN: Yes. In other words, if the peak
flows
06 were shifted to later in the season and after
the time when
07 the seed dispersal had occurred, yes, that would
be a
08 problem.
09 MR. DODGE:
Going on to Page 4 of your testimony, you
10 talk about the falling limb. As I
understand the falling
11 limb refers to diminishment of the high spring
runoff,
12 correct?
13 DR.
KAUFFMAN: Yes.
14 MR. DODGE:
You say:
15
Therefore, the rate of falling limb and the
16
level of base flows will influence the
17
structure of the riparian ecosystem. In
18
order to establish and perpetuate a healthy
19
riparian/preecosystem, a natural variability
20
of stream flows is crucial. (Reading.)
21 Do you see that
testimony?
22 DR.
KAUFFMAN: Yes, do I.
23 MR. DODGE:
Now, if in fact, DWP proposed to augment
24 high flows in Rush Creek through taking up to
150 cfs from
25 Lee Vining Creek, that would not be a natural
variability
0249
01 for Lee Vining Creek in wet years,
correct?
02 DR.
KAUFFMAN: How would it compare to the inherent
03 natural variability of the system? Would
it be a would
04 we never see the peak flows again? Would
there still be a
05 variability through decades of peak flows?
How would it
06 differ through time, through decadenal scales,
say, of peak
07 flows?
08 In other words,
what would be the vegetation? A single
09 event may not be significant. A complete
change in the
10 hydrographic would be significant.
11 MR. DODGE:
Taking up to 150 Cfs from Lee Vining Creek
12 in extreme and wet years, all of them, and
moving it over to
13 Rush Creek, would not provide a natural
variability for Lee
14 Vining Creek in wet years, would it?
Correct?
15 DR.
KAUFFMAN: Again, what percent? How would it
alter
16 may I ask Bob Beschta or someone how would
that alter the
17 hydrograph? How would it change the peak
flow of Lee Vining
18 Creek? I am afraid to make an incorrect
answer with the
19 amount of information I have. I would be
concerned, but I
20 would feel unqualified to answer that question.
21 MR. DODGE:
At Page 6 of your testimony, you say:
22
A gradual recession is optimal for vegetation
23
establishment as survival is dependent upon
24
root growth, maintaining connections with
25
adequate soil moisture. (Reading.)
0250
01 DR.
KAUFFMAN: Yes.
02 MR. DODGE:
Would you agree with me that taking 150 cfs
03 from Lee Vining Creek is not a gradual
recession?
04 DR.
KAUFFMAN: Yes. It comes back to the one table
on
05 what is the rate of what is it called?
the decreasing
06 ramping rates of 10 percent versus 15 percent
versus 25
07 percent. What are the natural rates of
decreasing limb or
08 falling limb or the decreasing ramping
rate. If that were
09 to be 15, 25 percent, I would be
concerned. Ten percent or
10 less, perhaps, the seedling growth of the
willows could keep
11 up with the decreasing water table.
12 MR. DODGE:
You were critical, Dr. Kauffman, of the
13 rewatering of Channel 10. Do you recall
that testimony?
14 DR.
KAUFFMAN: Yes, I do.
15 MR. DODGE:
In fact, this is not the first time. You
16 have been critical before of Rush restoration
efforts in the
17 Mono Basin, correct?
18 DR.
KAUFFMAN: I have been critical of those that have
19 not been done when I felt that the attempts at
restoration
20 caused more ecological harm than good.
21 MR. DODGE:
Let me ask you to look at a photograph that
22 Mr. Vorster is going to distribute.
23 MR.
BIRMINGHAM: May we see copies?
24 MR. DODGE:
He is moving as fast as he can.
25 MR.
BIRMINGHAM: This is already in the record.
0251
01 CHAIRMAN
CAFFREY: Is this an exhibit that is already
02 in the record?
03 MR. DODGE:
No, it is not in the record.
04 CHAIRMAN
CAFFREY: Don't we need to identity it? I
05 think we do. See if there is any
objection.
06 MR. DODGE: I
will identity this as Exhibit
07 RNAS/MLC8.
08 CHAIRMAN
CAFFREY: I'm assuming this comes under the
09 definition of crossexamination still, and not
direct.
10 MR. DODGE:
You betcha.
11 CHAIRMAN
CAFFREY: And you're down to about two
12 minutes. We do need to move on, Mr.
Dodge.
13 MR. DODGE: I
am moving as fast as I can.
14 CHAIRMAN
CAFFREY: You have been up there an hour and a
15 half. Two minutes within an hour and a
half. We do need to
16 get onto a lot of other parties. Please
proceed with all
17 dispatch.
18 MR. DODGE:
Dr. Kauffman, do you recognize this as a
19 picture of creek, Rush Creek, that you saw in
1992?
20 DR.
KAUFFMAN: Yes.
21 MR. DODGE:
Were you critical of this?
22 DR.
KAUFFMAN: Yes, I suppose I was.
23 MR. DODGE:
Do you recall what you said in that regard?
24 DR.
KAUFFMAN: Exactly on this spot?
25 MR. DODGE:
Right.
0252
01 DR.
KAUFFMAN: What point in time?
02 MR. DODGE:
What were you critical of?
03 DR.
KAUFFMAN: Mostly the deposition of the spoils onto
04 areas of mid channel bars and gravel bars.
05 MR. DODGE:
Why were you critical of that?
06 DR.
KAUFFMAN: Because, again well, it is exactly
07 I am having a hard time seeing your point.
Mostly, what I'd
08 say here would be the deposition of spoils onto
the riparian
09 bank and stream.
10 MR. DODGE:
Would you point to me what riparian bank
11 you are concerned about?
12 DR.
KAUFFMAN: Probably the one here in the foreground
13 in the lower corner.
14 MR. DODGE:
You are concerned about whether that would
15 revegetate?
16 DR.
KAUFFMAN. I'd be concerned that it certainly would
17 be a different vegetation than what would be
occurring under
18 natural conditions.
19 MR. DODGE:
Do you recall making a bet? Do you recall
20 betting Scott Stine your paycheck this would
never naturally
21 vegetate in your lifetime?
22 DR.
KAUFFMAN: I could probably believe that I would
23 make a bet with Dr. Stine similar to that.
Again, I
24 probably like to be on the spot with him before
I pay him my
25 wager.
0253
01 MR. DODGE: I
am sorry
02 CHAIRMAN
CAFFREY: You need to answer the question,
03 sir.
04 DR.
KAUFFMAN: I said I have no in reality, I have
05 no recollection of making a bet.
06 CHAIRMAN
CAFFREY: There is the answer; he doesn't
07 remember.
08 MR. DODGE:
Do you I will represent to you that the
09 next document which I am marking as
RNAS/MLC9, the top
10 photograph shows the I will represent to
you, sir, that
11 the top photograph shows the site in 1993 and
the bottom
12 photograph shows on the site in 1995.
13 Would you agree
with me, Dr. Kauffman, there has been
14 revegetation?
15 DR.
KAUFFMAN: Mostly chrysothmanus nauseosus and
16 viscidiflorus, which are species of upland
disturbed
17 environments of the great basin.
18 MR. DODGE:
This was initially an upland basin, wasn't
19 it?
20 DR.
KAUFFMAN: No, it was not. I would say this
area
21 clearly should have at least be dominated by
tramings
22 [phon]; historically, an area at the bottom of a
toe slope
23 in the historical riparian zone most likely have
riparian
24 vegetation.
25 CHAIRMAN
CAFFREY: Mr. Dodge, how much more time do
0254
01 you think you need?
02 MR. DODGE: I
need another ten minutes, but I will take
03 a couple.
04 CHAIRMAN
CAFFREY: You need another ten, but you are
05 going to take just a couple. I am sure
everybody will have
06 no objection.
07 MR. DODGE:
Showing you the next document, sir, which
08 is RNAS/MLC10. I will represent to you
is a picture of
09 the site in 1995.
10 Would you agree
that riparian vegetation has returned
11 in your lifetime?
12 MR.
BIRMINGHAM: Excuse me, I haven't had an
13 opportunity to see these photographs. I
wonder if I can
14 have an opportunity before he examines the
witness on it.
15 CHAIRMAN
CAFFREY: Make sure everybody has copies.
16 MR. DODGE: I
am getting pressured from both ends.
17 CHAIRMAN
CAFFREY: Yes, you are. We have a long way to
18 go.
19 DR.
KAUFFMAN: I am sorry, Mr. Dodge, but seems that
20 the picture where we see riparian vegetation
down below
21 looks like it is just upstream of where the
bulldozers are.
22 There is no damage or destruction.
23 Does that look
right to you?
24 MR. DODGE:
Would you agree with me that in 1995 that
25 riparian vegetation has returned to this site in
your
0255
01 lifetime?
02 DR.
KAUFFMAN: The picture that I see on the bottom,
03 this one, it appears that it is not area that
was destroyed
04 here. This is picture we are looking
upstream of the heavy
05 equipment.
06 Can I refer to
Brian to see if I am correct?
07 MR.
TILLEMANS: I remember this site really well.
If
08 you want to know what was there before and what
is there now.
09 MR. DODGE: I
am running out of time. I will pass.
10 DR.
KAUFFMAN: I did visit and vegetation map that
11 site. I would be happy to provide you with
the information
12 of what we classified it as. That would
have an idea of
13 what the dominance and subdominance are in that
very site.
14 MR. DODGE:
Thank you, sir.
15 CHAIRMAN
CAFFREY: Thank you, Mr. Dodge.
16 Let's go to
Virginia Cahill, representing Department of
17 Fish and Game.
18 MS. CAHILL:
Because I switched with Mr. Dodge, I
19 didn't want to displace Ms. Scoonover.
20 CHAIRMAN
CAFFREY: I just was going to go back to the
21 regular order if there is no problem with that.
22 MS. CAHILL.
That is fine.
23 CHAIRMAN
CAFFREY: Is that all right with you, Ms.
24 Scoonover?
25 MS.
SCOONOVER: I am used to batting cleanup.
0256
01 MR.
BIRMINGHAM: She acknowledges this is one team
02 against another.
03 CHAIRMAN
CAFFREY: Good evening. We don't say that
04 too often.
05
oOo
06
CROSSEXAMINATION
07
BY THE DEPARTMENT OF FISH AND GAME
08
BY MS. CAHILL
09 MS. CAHILL:
Good evening to the members of the panel,
10 as well.
11 Mr. Kavounas, I
remember Mr. Dodge asking you some
12 questions about whether or not you had rejected
the
13 socalled Ridenhour Plan because you felt it
was
14 inconsistent with Decision 1631.
15 Do you remember
that?
16 MR.
KAVOUNAS: Yes, I do.
17 MS. CAHILL:
And you felt it was inconsistent because,
18 in fact, it would reduce exports allowable to
Los Angeles
19 under that Decision. Is that right?
20 MR.
KAVOUNAS: Yes.
21 MS. CAHILL:
If the Monitoring Plan that is being
22 proposed now were to demonstrate that the
restoration of
23 Rush Creek required the flows, recommended in
the Ridenhour
24 Plan, would D1631 then be implemented or
violated if those
25 flows were imposed?
0257
01 MR.
KAVOUNAS: You seem to place an emphasis on the
02 Ridenhour Plan. I would rather not.
Our intent here is to
03 have an adaptive management plan, and we are
committed that
04 if that adaptive management plan, along with
monitoring,
05 indicates that higher flows are necessary, the
Department is
06 committed to implementing the higher flows.
07 MS. CAHILL:
Even if they reduce exports below the
08 numbers in 1631?
09 MR.
KAVOUNAS: That's correct.
10 MS. CAHILL:
So, you recognize, in fact, that D1631
11 itself indicated that modification of
restoration activities
12 may reduce the amount of water available for
export?
13 MR.
KAVOUNAS: Is that the famous paragraph 8(F)(8) of
14 the decision?
15 MS. CAHILL:
8(F)(8), indeed it is.
16 MR.
KAVOUNAS: Yes.
17 MS. CAHILL:
So you are familiar with it?
18 DR.
KAUFFMAN: Yes, I am.
19 MS. CAHILL:
Thank you.
20 MR.
KAVOUNAS: I think no one questions the continued
21 jurisdictions set forth.
22 MS. CAHILL:
Dr. Kauffman, could you read to us from
23 your testimony the definition of restoration
that you are
24 using?
25 DR.
KAUFFMAN: Sure. Ecologic this is from
Page 2
0258
01 of my testimony. It is the National
Research Council on
02 Wetlands Restoration, 1992. Ecological
restoration of
03 riparian ecosystems/riparian restoration is
defined as:
04
The reestablishment, predisturbance riparian
05
function and related chemical, biological,
06
and hydrological characteristics. It is the
07
process of repairing damage caused by humans
08
to the diversity and dynamics of indigenous
09
ecosystems. Jackson, et al., 1995.
10
(Reading.)
11 MS. CAHILL:
Do all members of the panel with expertise
12 in any area agree with that definition?
13 Do any of you
disagree?
14 At least one of
you I heard today say that each reach
15 has its own potential.
16 Dr. Kauffman, do
you agree with that?
17 DR.
KAUFFMAN: Yes, I do.
18 MS. CAHILL:
And do you, Dr. Beschta?
19 DR. BESCHTA:
Yes.
20 MS. CAHILL:
Is there anyone on the panel who disagrees
21 with that statement?
22 Do you all agree
that each stream has its own
23 potential?
24 Does anyone
disagree?
25 DR. BESCHTA:
It has a range of potentials.
0259
01 MS. CAHILL:
A range of potentials.
02 Let's discuss,
briefly, the pre1941 condition in Reach
03 1 of Rush Creek.
04 Can one of you
tell me how long Reach 1 was prior to
05 1941? Or let me be more clear. How
much of the present day
06 Rush Creek in Reach 1 was watered prior to 1941?
07 MR.
KAVOUNAS: When you say watered, do you mean flow
08 through conditions?
09 MS. CAHILL:
Yes.
10 Is there now a
2800foot stretch of Rush Creek that is
11 usually dry that usually carried water in
predisturbance
12 conditions?
13 MR.
KAVOUNAS: My understanding is that prediversion,
14 preLADWP diversion, Reach 1 was used by
irrigators in the
15 area who had dams that would result in
diversions, such as
16 the A ditch. And it my understanding that
what we refer
17 today as Reach 1 had water that resembled more
standing
18 conditions than flow through conditions.
19 MS. CAHILL:
Predisturbance, what would Reach 1 have
20 been?
21 If our definition
of restoration is to go back to
22 predisturbance, what would we have had?
23 MR.
KAVOUNAS: I can't answer that.
24 DR. BESCHTA:
We would have had a stream which had been
25 fed by Grant Lake.
0260
01 MS. CAHILL:
Prior to 1941, was there water at least in
02 that stretch?
03 MR.
KAVOUNAS: Again, my understanding is that water
04 was ponding up, so there was water in conditions
that
05 resembled standing water conditions.
06 MS. CAHILL:
Is it your understanding that the entire
07 reach, that is now called Reach 1, was ponded
was there
08 current in the upper end of it?
09 MR.
KAVOUNAS: I don't know.
10 MS. CAHILL:
Were there fish in Reach 1 prior to 1941?
11 Any member of the panel.
12 CHAIRMAN
CAFFREY: Anybody have an answer?
13 MS. CAHILL:
Does any member of the panel have reason
14 to believe there were not fish in Reach I prior
to 1941?
15 Let the record
reflect there seems to be no one who is
16 indicating that is positive response to that
question. No
17 one is indicating that they were aware that
there was not
18 fish.
19 Dr. Kauffman,
given what we do know about Reach 1
20 predisturbance, will the existing Los Angeles
Water and
21 Power Stream Plan restore Reach 1; that is, will
the
22 existing plan restore the predisturbance
condition in the
23 way that you have defined restoration?
24 DR.
KAUFFMAN: No.
25 MS. CAHILL:
With adequate flows, could Reach 1 be
0261
01 restored, in your opinion, Dr. Kauffman?
02 DR.
KAUFFMAN: I would say I have I would say I
03 don't know because I don't know what the impact
and the
04 geomorphology of that reach has been during the
dam building
05 operations.
06 MS. CAHILL:
Mr. Tillemans, you have shown us a number
07 of photographs today of various reaches of Rush
Creek and
08 indicated what fantastic, phenomenal recovery is
happening
09 on those reaches.
10 Did any of your
photographs cover Reach 1?
11 MR.
TILLEMANS: None in the exhibits.
12 MS. CAHILL:
Are you all familiar with Department of
13 Fish and Game Exhibits RDF&G7A and
7B? These are in the
14 record. I have just one copy for the
witness and one for
15 the Board, just to pass around?
16 CHAIRMAN
CAFFREY: We will pass. That's all right.
17 We will later lay
a foundation for this, that it was
18 taken in 1994.
19 Dr. Kauffman, if
you can have the chance to look at
20 either of these pictures, would this Reach 1
meet your
21 definition of restoration?
22 DR.
KAUFFMAN: No.
23 MS. CAHILL:
Are you, Mr. Tillemans, familiar with
24 Reach 1 this past year?
25 MR.
TILLEMANS: Yes, I am.
0262
01 MS. CAHILL:
Would you consider that Reach 1 has been
02 restored at this time?
03 MR.
TILLEMANS: Restored to?
04 MS. CAHILL:
To predisturbance conditions.
05 MR.
TILLEMANS: Not to predisturbance conditions.
Are
06 you talking preman or
07 MS. CAHILL:
We can do it in two parts. We can do
08 preany disturbance. Has there been
return to
09 predisturbance?
10 MR.
TILLEMANS: Prior to preEuroAmerican
settlement.
11 How's
that?
12 MS. CAHILL:
Or pre1941, has it been returned to
13 pre1941 conditions?
14 MR.
TILLEMANS: In the past year I have seen water in
15 this reach that's been flooded, and I have seen
wetland
16 vegetation come up and above in response to the
vegetation.
17 But I am not sure if it is a hundred percent
pre41.
18 MS. CAHILL.
Those indices that you have been speaking
19 of, the healthy dynamic stream system, those are
not present
20 in Reach 1 at this time?
21 MR.
TILLEMANS: No, they are not.
22 MS. CAHILL:
Do any of you believe they are? If you
23 look in the photograph, is there dead riparian
vegetation
24 that is visible?
25 DR. BESCHTA:
Looks like there is dead woody species
0263
01 alongside.
02 This was taken
when?
03 MS. CAHILL:
1994.
04 DR. BESCHTA:
When I was out there, I believe there was
05 water.
06 DR.
KAUFFMAN: In that spot, yeah.
07 MS. CAHILL.
There may be temporarily. There is no
08 consistent flows through that reach; is that
correct?
09 DR. BESCHTA:
No.
10 MS. CAHILL:
Your plan does not provide for any
11 consistent flow in that reach, does it.
12 MR.
KAVOUNAS: No, it does not.
13 MS. CAHILL:
There is in testimony of, I think, Dr.
14 Beschta and maybe others of you, some suggestion
of
15 releasing some flows from the return
ditch. That proposal
16 is not spelled out.
17 Can you tell me
what it is that you are proposing?
18 Was that in your
testimony, Dr. Beschta?
19 DR. BESCHTA:
That was in my testimony. You want me to
20 tell you my testimony again? When I saw
it, there was water
21 in this channel. My suggestion would be is
that you rewater
22 it with flow from Mono ditch, take some water
and put it
23 into there. The alternative, as I
indicated in my
24 testimony, it looks like it is a very expensive
reach to
25 rewater. If somebody wants to spend that
money, that's an
0264
01 incredible amount of money for brown trout
habitat. I
02 guess, that is a choice someone else can make.
03 MS. CAHILL:
In your first proposal you indicate in the
04 testimony where that water could come off the
return ditch,
05 where it exactly would go into Reach 1?
06 DR. BESCHTA:
It is a fairly easy movement to bring
07 water around the ditch and into this
reach.
08 MS. CAHILL.
At the base of the dam?
09 DR. BESCHTA:
No, it would not come in at the base of
10 the dam.
11 MS. CAHILL:
So, you would not rewater the entire reach?
12 DR. BESCHTA:
It would be rewatered up to the base of
13 the dam, as I remember being out there.
14 MS. CAHILL:
Would this amount of water that you are
15 proposing restore the stream in terms of
establishing the
16 processes that would restore its prediversion
condition?
17 DR. BESCHTA:
Well, the prediversion condition, I
18 guess, it depends upon when you start the
clock. To be
19 quite honest, I have not focused a great
deal. I have to go
20 back and look at the photographs and things
like, pre1941,
21 if that is the question you are asking.
What did it look
22 at, pre41?
23 The dam was moved,
and I am not sure how far that was
24 moved down into that reach. I would have
to go look at
25 that. If you wanted to maintain what I saw
when I was
0265
01 out there, there was water in that system.
If you want to
02 maintain wetland conditions, you could do so
relatively
03 easily by bringing water off the Mono Ditch.
04 MS. CAHILL:
What if you wanted to maintain fish
05 habitat equivalent to the fish habitat that was
available
06 predisturbance?
07 DR. BESCHTA:
I have no know knowledge of fish habitat,
08 so I don't know
09 MS. CAHILL:
Mr. Kavounas, this proposal to bring some
10 small amount of water, which I understand one
cfs or two,
11 from the Mono Ditch to Reach 1, is that, in
fact, now a part
12 of the Los Angeles plan?
13 MR.
KAVOUNAS: No, it is not.
14 MS. CAHILL:
So, the Los Angeles plan makes no attempts
15 to rewater Reach 1; isn't that correct?
16 MR.
KAVOUNAS: That is correct. That is because
the
17 Department of Water and Power provided a hot
creek for fish
18 hatchery for the Department of Fish and Game in
lieu of the
19 fish that were in Reach 1.
20 MS. CAHILL:
In lieu of fish passage, but that is a
21 legal issue that I will deal with separately.
22 With regard to the
three scientists' report, their work
23 plan, did the three scientists recommend a new
release
24 facility at Grant Dam that could release water
into Reach 1?
25 DR. TRUSH: I
don't believe so. Get nailed here. I
0266
01 am trying to remember. I don't think
so.
02 MS. CAHILL:
Did the three scientists recommend the
03 rewatering of Reach 1?
04 Let me find it and
come back.
05 DR. TRUSH: I
would have to look.
06 MR. HUNTER:
That is not my recollection either, but I
07 could be wrong.
08 MS. CAHILL:
What about the ad hoc committee; what was
09 the ad hoc committee's recommended alternative?
10 DR. TRUSH:
What I remember, there was nothing about
11 Reach 1 in that ad hoc committee.
12 MS. CAHILL:
Let me refer you to the ad hoc committee'
13 letter, which is Appendix 7 to the Grant Lake
Operations and
14 Management Plan. If I could ask you, Dr.
Trush, to read
15 what I have marked here on Page 2, toward the
bottom. And I
16 have extra copies of this. This is already
in evidence. If
17 you can take some up to the Board.
18 DR. TRUSH:
This very last paragraph?
19 MS. CAHILL:
And the continuation on the next page.
20 DR. TRUSH:
Construction of new facility to
21
release water from Grant Lake Reservoir
22
directly into Rush Creek immediately below
23
the dam, either independent of or in
24
coordination with, use of Mono Ditch. This
25
is the preferred alternative. Would require
0267
01
the capability to release water directly
from
02
Grant Lake Reservoir, provide the
flows
03
recommended by the stream scientists in
their
04
draft restoration plan. This alternative
is
05
considered to be the most reliable in terms
of
06
providing volumes, timing, magnitude, and
07
duration of water needed to mimic the
hydrograph
08
as originally recommended by the stream
09
scientists to restore and maintain stream habitat,
10
including Reach 1 of Rush Creek Lake Reservoir.
11
(Reading.)
12 MS. CAHILL:
Do you now recall that language?
13 DR. TRUSH:
No, I still don't. To be honest with you,
14 I just don't. I am fairly, throughout the
RTC, not
15 concerned with Reach 1. It has been my
stand all along, and
16 I really don't have any recollection of that
paragraph.
17 MS. CAHILL:
Perhaps I will ask Dr. Ridenhour when he
18 is on the stand.
19 With regard to the
Mono Gate Return Ditch, which of you
20 is most familiar with the design of the proposed
21 rehabilitation of the return ditch? Would
that be you, Mr.
22 Kavounas?
23 MR.
KAVOUNAS: No design has been completed at this
24 point in time.
25 MS. CAHILL:
To the extent that rehabilitation of the
0268
01 return ditch is discussed in Appendix 3 to the
stream plan,
02 isn't it true that it calls for removing
boulders, large
03 debris, and aquatic growth along the channel
walls to the
04 extent possible?
05 MR.
KAVOUNAS: That sounds familiar.
06 MS. CAHILL:
Riprap may be installed; is that true.
07 MR.
KAVOUNAS: Which appendix was that?
08 MS. CAHILL:
Appendix 3 to the Grant Lake Plan, Page
09 4.
10 MR.
KAVOUNAS: You are looking at which paragraph on
11 there?
12 MS. CAHILL:
Paragraph 1. The ditch will be dredged to
13 its original depth, boulders, large debris, and
aquatic
14 growth along the channel which inhibit or impair
the flow in
15 the channel will be removed to the extent
possible.
16 MR.
KAVOUNAS: Okay.
17 MS. CAHILL:
I am pretty sure somewhere it says riprap
18 may be installed. Is that your memory of
what the proposal
19 is in the appendix?
20 MR.
KAVOUNAS: Yes. I see that next page, Page 5,
the
21 second paragraph, Number 4, install riprap as
necessary.
22 MS. CAHILL:
And the channel will be straightened; is
23 that correct?
24 MR.
KAVOUNAS: I don't recall that as part of the
25 proposal. I should point out I didn't
write this. So if
0269
01 you say that is in there, I will believe you.
02 MS. CAHILL:
Who did write this?
03 MR.
KAVOUNAS: That was written by, I believe, Mr. V.
04 Miller of our staff.
05 MS. CAHILL:
The ditch will be made a constant grade
06 throughout. Do you believe that is part of
this proposal?
07 MR.
KAVOUNAS: No, I am sorry I don't recall that.
08 MS. CAHILL:
On Page 5, Paragraph 5, b, making the
09 ditch constant grade throughout. In fact,
that is where c
10 is also, straighten the channel bed to the
degree possible.
11 MR.
KAVOUNAS: Okay. I am with you.
12 MS. CAHILL:
Now, let me ask one of the fisheries'
13 biologists. Dr. Platts, do you believe
when the channel is
14 straightened, made even, riprapped with its
boulders
15 removed, the aquatic vegetation removed, it will
be good
16 fish habitat?
17 DR. PLATTS:
Well, that is tough. I doubt it, but I
18 can't be sure on that.
19 MS. CAHILL.
If there were no vegetation on the banks,
20 is it likely to be good fish habitat?
21 DR. PLATTS:
Again, I don't know. In Idaho or
22 Richfield Canal, there is tremendous
fishing. Whether this
23 turns to be one, I don't know. All I can
say is, I doubt it
24 would be real fish
habitat.
25 MS. CAHILL:
That ditch wouldn't have the sort of
0270
01 attributes that you are looking for in the
natural stream
02 for restoration, would it?
03 DR. PLATTS:
That is right.
04 MS. CAHILL:
Who talked about the attributes?
05 Dr. Trush, would
this ditch with that configuration, be
06 likely to have the attributes you are looking at
in the regs
07 for Rush Creek in order to restore it?
08 DR. TRUSH:
No.
09 MS. CAHILL.
Do you believe it would be good fish
10 habitat?
11 DR. TRUSH:
No.
12 MS. CAHILL.
Dr. Hunter?
13 MR. HUNTER:
I am not a doctor.
14 With the exception
of the riprap, it doesn't sound like
15 it would be very good habitat.
16 MS. CAHILL:
Thank you.
17 Mr. Kavounas, who
calculated the cost of the new Grant
18 Dam release facility that is found in your
stream plan?
19 MR.
KAVOUNAS: Again, it was Mr. V. Miller of our
20
staff.
21 MS. CAHILL:
He is not going to be a witness here
22 today, is he?
23 MR.
KAVOUNAS: No. We received no comments on the
cost
24 estimates. When comments were submitted to
the State Board
25 on our final plans, with the exception of one,
there were no
0271
01 comments on the cost estimates provided in the
plan.
02 MS. CAHILL:
I am quite sure the Department of Fish and
03 Game commented that the cost estimates were in
no way broken
04 down, and we wanted additional detail.
05 MS.
KAVOUNAS: Yes. You're correct.
Additional
06 detail, I believe, was provided.
07 MS. CAHILL.
No, it was not. Is there anything in the
08 record other than the simple number of
13somemillion
09 dollars that explains how that cost was arrived
at?
10 MR.
KAVOUNAS: I am under the impression that we
11 provided a detailed cost breakdown to State
Water Board
12 staff. And it is my understanding that
that is available to
13 all to examine. And I believe Mr. David
Allen spent some
14 time compiling the cost estimates.
15 MS. CAHILL:
May I ask the Board staff if that is true?
16 CHAIRMAN
CAFFREY: Please do.
17 MR. CANADAY.
Yes. I recall that the City did submit a
18 more detailed cost breakdown to the State Board,
but I am
19 not aware of what the distribution was, other
than we have a
20 copy of it.
21 MS. CAHILL:
We have not seen it.
22 MS.
GOLDSMITH: We have not seen it either.
23 MS. CAHILL:
To the extent there is evidence in the
24 record that we have seen, the only thing we saw
was the
25 ultimate conclusionary number.
0272
01 CHAIRMAN
CAFFREY: Could we get copies for the
02 parties?
03 MR. ALLEN:
Let me add on the same topic.
04 CHAIRMAN
CAFFREY: Before you do that, I have question
05 on the floor, sir. I am asking my staff
that question
06 here.
07 MR. CANADAY:
I will have to go back to the record and
08 look for it.
09 Do you know the
proximate date, Mr. Kavounas?
10 MR.
KAVOUNAS: I would be guessing. My guess would
be
11 some time in mid to late March of 1996.
12 MR. CANADAY:
A month is fine. I will go back and I
13 will check to see if I can find it.
14 CHAIRMAN
CAFFREY: Thank you, Mr. Canaday.
15 MR.
KAVOUNAS: If not, we could help.
16 CHAIRMAN
CAFFREY: Yes, Mr. Del Piero.
17 BOARD MEMBER DEL
PIERO: Mr. Chairman, it might be
18 easier for Los Angeles to provide it rather than
have Mr.
19 Canaday look for it.
20 CHAIRMAN
CAFFREY: Mr. Del Piero suggests that it might
21 be easier for you to provide than have Mr.
Canaday to spend
22 precisely half the night looking for it.
23 MR.
KAVOUNAS: If I may clarify, I couldn't do that
24 tonight. It is my correspondence
files are still in my
25 office in Los Angeles.
0273
01 CHAIRMAN
CAFFREY: Mr. Canaday, see if you can come up
02 with it, then. If that doesn't produce
anything, then we
03 will have to try something else tomorrow.
04 Mr. Birmingham.
05 MR.
BIRMINGHAM: I understand the Fish and Game
06 interest in seeing the cost breakdown. In
fact, the Mono
07 Lake Committee and National Audubon Society have
also
08 submitted a cost estimate for construction of a
09 facility. And I am not sure that, in terms
of estimates,
10 there is that much of a difference between the
two, the two
11 cost estimates.
12 MS. CAHILL:
The difference is the National Audubon
13 Society broke it down into subcomponents so
people could
14 assess whether it was reasonable. All that
we have seen
15 from Los Angeles is an end number, a total
number.
16 MR.
BIRMINGHAM: Mr. Chairman, I was trying to save Mr.
17 Canaday having to go through the file.
18 CHAIRMAN
CAFFREY: Appreciate your effort there, Mr.
19 Birmingham, but if they haven't seen, and they
would like
20 to, I think it is appropriate that they do.
21 MS. CAHILL:
There is a difference of at least
22 $2,000,000 in the two estimates, also. It
is the final.
23 Mr. Kavounas, how
long has Grant Dam been there?
24 MR.
KAVOUNAS: Since the new dam. I believe it was
put
25 in operation in 1941.
0274
01 MS. CAHILL:
How long do you expect it to remain in
02 operation?
03 MR.
KAVOUNAS: I have no opinion on that.
04 MS. CAHILL.
Los Angeles isn't intending to abandon it
05 at any time in the next 50 years?
06 MR.
KAVOUNAS: I am not so sure about that.
07 MS. CAHILL:
If there were a new release facility
08 installed, what would be the useful life of that
release
09 facility?
10 MR.
KAVOUNAS: I have no opinion on that.
11 MS. CAHILL:
Let's assume that we installed a release
12 facility and it had a useful life of 50
years. If the cost
13 was approximately $13,000,000, would you agree
then that the
14 cost per year would be something like $260,000 a
year?
15 MR.
KAVOUNAS: Do you include depreciation in that?
16 MS. CAHILL:
No, just construction.
17 MR.
KAVOUNAS: Then I have no opinion on that.
18 BOARD MEMBER DEL
PIERO: Excuse me.
19 CHAIRMAN
CAFFREY: Mr. Del Piero.
20 BOARD MEMBER DEL
PIERO: What governmental agency
21 depreciates its facilities?
22 MR.
KAVOUNAS: I don't know.
23 BOARD MEMBER DEL
PIERO: Then what was the purpose of
24 the question?
25 MR.
KAVOUNAS: What I am saying is I don't know enough
0275
01 about how facilities are depreciated. I am
not so sure what
02 capital considerations go in an agency. I
am saying I don't
03 know.
04 BOARD MEMBER DEL
PIERO: Okay.
05 MS. CAHILL:
Is it true that the stream plan itself
06 indicated that the release facility option would
result in
07 the greatest control and would minimize
operation and
08 maintenance costs?
09 MR.
KAVOUNAS: To my recollection, yes.
10 MS. CAHILL:
If the release facility is built, is it
11 your understanding that you would then be
permitted to
12 abandon the return ditch entirely?
13 MR.
KAVOUNAS: I believe so, yes.
14 MS. CAHILL:
And say
15 MR.
KAVOUNAS: Excuse me. Although I do believe in
16 order to construct an outlet from Grant Lake, we
would also
17 have to rehabilitate the return ditch.
18 MS. CAHILL:
The ongoing return ditch maintenance could
19 be avoided?
20 MR.
KAVOUNAS: I believe you are correct.
21 MS. CAHILL:
Can you tell me who prepared the proposal
22 with regard to sediment bypass at Lee Vining
Creek?
23 MR.
KAVOUNAS: I did.
24 MS. CAHILL:
Dr. Beschta, I recall, with regard to
25 sediment bypass, you indicated that at this
point you are
0276
01 not certain in you own mind what the preferred
method for
02 passing sediment is; is that correct?
03 DR. BESCHTA:
That is true. In my mind there are still
04 unknowns as far as amounts of sediment moving at
certain
05 times, how much you would have to pass on an
annual basis,
06 questions like that. And, also, once you
make that
07 decision, if you decide to go, there is an
engineering
08 concern with regard to what to do.
09 I am not a civil
engineer. I would not be I would
10 not want to provide testimony with regard to
what kind of
11 structure you have to build.
12 MS. CAHILL:
Dr. Platts, when Mr. Kavounas was
13 designing a sediment bypass facility, did he ask
you whether
14 the proposal he was developing would possibly
cause any harm
15 to the fishery?
16 DR. PLATTS:
No.
17 MS. CAHILL:
Do you have any opinion? Have you
18 reviewed the sediment bypass proposal?
19 DR. PLATTS:
Only briefly. I have looked at it, but
20 very briefly.
21 MS. CAHILL:
Do you have an opinion from the brief
22 review that you have done?
23 DR. PLATTS:
Yeah, I don't like it.
24 MS. CAHILL:
Mr. Hunter, have you reviewed the sediment
25 bypass proposal?
0277
01 MR. HUNTER:
If I have, I don't recall what it was.
02 MS. CAHILL.
Dr. Platts, would you tell us what it is
03 you don't like about it?
04 DR. PLATTS:
I don't believe, in the long run, that it
05 will move sediments at the right time of the
year. I think
06 that it would cause some problems below the dam,
and I don't
07 think it is going to do it in a natural enough
way that it
08 would take care of the fish habitat needs
immediately below
09 the dam. And there is probably a better
way to do it.
10 MS. CAHILL:
With regard to woody debris, Mr.
11 Tillemans, I think your testimony is that you
will place
12 woody debris that is currently stockpiled at
Cain Ranch; is
13 that right?
14 MR.
TILLEMANS: Yes, that is correct.
15 MS. CAHILL:
Are you also still intending to take woody
16 debris that is on the floodplain and put it in
the channel
17 or has that proposal been abandoned?
18 MR.
TILLEMANS: No, it has not been abandoned.
19 Although, based on the recent observations, kind
of question
20 the necessity for it.
21 MS. CAHILL:
The woody debris that is on the floodplain
22 now, is it in some way serving as wildlife
habitat where it
23 is?
24 MR.
TILLEMANS: Yes.
25 MS. CAHILL:
Just for everyone's information, there
0278
01 seems to be, Dr. Beschta, some areas in which
you were
02 varying from the stream plan with regard to
watering certain
03 channels. And I think it would just help
us all to go
04 through and mark what the plan was, what your
proposal was
05 and clarify with Mr. Kavounas whether your
proposal is now
06 the plan or whether the plan is the plan.
07 Does that make
sense?
08 MR. DODGE: I
would object to that line of
09 questioning. It is asked and
answered.
10 CHAIRMAN
CAFFREY: I am sorry, I didn't hear the last
11 part of what you said, Mr. Dodge.
12 MR. DODGE:
The question has been asked and answered.
13 I asked that question and he said the plan was
in Exhibit
14 16.
15 MS. CAHILL:
Let's see the first part. I would like to
16 at least see what the plan proposed and what Dr.
Beschta has
17 testified.
18 This is already in
evidence in this exact form. It is
19 Figure 34 of the stream scientists' report,
which is an
20 appendix to one of these plans. It is from
Stine 1992, that
21 I suspect is also in evidence.
22 Dr. Beschta, if I
could ask you, this is only below the
23 Narrows. Let's do it first. If you
could mark in yellow
24 those additional channels that the stream plan
proposes
25 rewatering.
0279
01 MR.
BIRMINGHAM: Mr. Caffrey.
02 CHAIRMAN
CAFFREY: Mr. Birmingham.
03 MR.
BIRMINGHAM: While Dr. Beschta is marking that,
04 some of our witnesses who are going to be on the
Waterfowl
05 Habitat Restoration Program and a number of
parties I see
06 Mr. Mooney is here may not way to stay if
it is not
07 likely we will get started with that testimony
tonight.
08 I wonder if we can
09 CHAIRMAN
CAFFREY: Take a little time to figure out
10 where we going tonight?
11 MR.
BIRMINGHAM: Yes.
12 BOARD MEMBER DEL
PIERO: You think they have something
13 better to do?
14 CHAIRMAN
CAFFREY: I would like I want to hear from
15 the waterfowl panel this evening. I don't
know what you
16 have by way of redirect, if any, and what we
have by way of
17 recross, so I wish I could tell you when we are
going to get
18 there. You have 24 minutes left, by the
way, to present
19 that panel. And, I wish I could tell you
that I know when
20 we are going to get to it.
21 Part of the reason
that we are going into the night
22 sessions is that we are not moving among real
fast, and I am
23 not sure that we could move any faster.
This is a complex
24 matter, but at the moment, I am trying to get to
that part
25 of the process.
0280
01 MS. CAHILL:
Mr. Smith tells me the timer is not off.
02 BOARD MEMBER
BROWN: That was a check to see if you
03 were paying attention.
04 CHAIRMAN
CAFFREY: You're scaring me. That means that
05 you are going to use the whole hour. I
apologize. We
06 probably owe you about how long was I
talking?
07 Mr. Del Piero has
nowhere to go tonight, I take it.
08 BOARD MEMBER DEL
PIERO: You always talk longer.
09 CHAIRMAN
CAFFREY: You finally got me. Thank you,
10 Marc.
11 Let's go along a
little bit here and see. I am not at
12 the point where I am ready to say we can't get
to the direct
13 on the waterfowl panel. I am not there
yet, sorry.
14 BOARD MEMBER
BROWN: The timer will cut you some slack
15 here, Ms. Cahill.
16 MS. CAHILL:
If this is a problem, it just seemed to me
17 to be the clearest, fastest way to clarify
something, at
18 least to me, was not clear.
19 CHAIRMAN
CAFFREY: I don't have a problem with it.
20 MS. CAHILL:
Dr. Beschta, have you work
21 DR. BESCHTA:
Would you mind at all if Brian Tillemans
22 puts it on the map? If I get it on the
wrong spot
23 MS. CAHILL:
That would be fine. Actually, whoever
24 would like to.
25 DR. BESCHTA:
Then I would be glad to provide any
0281
01 comments.
02 MS. CAHILL:
That would be great.
03 This is below the
Narrows. We will have to talk
04 upstream, too.
05 MR.
TILLEMANS: May I clarify? These channels that
are
06 being proposed here in the context of what I
used to say
07 which channels we were going to rewater?
08 MS. CAHILL:
Sure. Whatever you need to explain.
09 MR.
TILLEMANS: It was the recommendations that were
10 proposed in draft Ridenhour, Trush and Hunter
Restoration
11 Report.
12 MS. CAHILL:
Was it your intent in doing the stream
13 plan to incorporate, without change, the
scientists'
14 recommendations with regard to rewatering?
15 MR. TILLEMANS: I
think when this plan was written,
16 yes.
17 MS. CAHILL:
Because in some cases, for example, the
18 scientists recommending 10 cfs, but only when
flows were 47.
19 In your plan it was just carried over as 10
cfs.
20 Would you have
intended, had you thought about it, to
21 incorporate theirs as they were proposing
it?
22 MR.
TILLEMANS: Yes. I did intend to do that as
they
23 requested at that time.
24 MS. CAHILL:
Could you just then mark that, and with
25 that whatever explanation you feel you need to
give.
0282
01 MR.
TILLEMANS: You want the bottomland channels now?
02 MS. CAHILL:
Whatever shows on that.
03 MR.
TILLEMANS: The abandoned east side 1A channel in
04 Reach 4A, which would be this complex
here.
05 MS. CAHILL:
Go ahead and mark it with the yellow.
06 MR.
TILLEMANS: This is not exact because the entrances
07 haven't been determined yet, as in their plan as
well.
08 Somewhere in
vicinity.
09 CHAIRMAN
CAFFREY: I don't think anybody can see that.
10 MS. CAHILL:
Once we have marked it, it will be unique,
11 so then I think it will be a new exhibit, and we
will make
12 DFG next in order, which will be
RDFG9.
13 MR.
TILLEMANS: I am uncomfortable with the details on
14 this, but I will try to get it in the vicinity.
15 CHAIRMAN
CAFFREY: Mr. Tillemans, do you want to take
16 that mike. You can actually slide that
mike out of that.
17 There you go. You can hold it in one
hand.
18 MR.
TILLEMANS: Thank you.
19 The 4Bii
complex.
20 MS. CAHILL:
Has that one actually been done?
21 MR.
TILLEMANS: This one has had flood water through it
22 already and has standing water, in fact, and
fish.
23 And I am not quite
sure how these channels go. It
24 would be the 4Bii complex and, basically,
rewatering because
25 open up an entrance. It doesn't include
channel works. So
0283
01 whatever that entrance would entail as a
stream.
02 In Reach 4C, which
was described by the Ridenhour,
03 Trush, and Hunter plan, near elevation 64A to
6451, I don't
04 think that exact entrance has been picked as
yet. We do
05 have some aerial videos that show some likely
places to put
06 an entrance in.
07 BOARD MEMBER DEL
PIERO: That is not demonstrated on
08 this map.
09 MR.
TILLEMANS: That is the old meander bend. It
is
10 upstream of the ford. I don't think it is
on this map. I
11 would defer to Trush and Hunter because it is
the same
12 channel.
13 DR. TRUSH:
Of the three RTC folks, Rich has the iron
14 memory on I don't know what the protocol
is. Rich might
15 help us out. I am a blank on 4C.
16 MR.
TILLEMANS: It is not on this map.
17 MS. CAHILL:
Okay.
18 So those are the
only ones that are on that map?
19 DR. BESCHTA:
Just two.
20 MR.
TILLEMANS: I have to clarify. The Channel 10
21 complex has already been completed.
22 MS. CAHILL:
Dr. Beschta, the ones that you proposed
23 either not to do or to do in a different matter,
which are
24 they?
25 DR. BESCHTA:
I would propose both of these are
0284
01 unnecessary. They both, when I was in the
field in June,
02 had water in them. It was subsurface
water. It was
03 hyporheic water that was already coming from the
channel,
04 moving subsurface and showing up in the
depression. So,
05 they already had water in them. I guess if
you want flowing
06 water from the stream, that is a bit different,
but you've
07 already got water moving through them right
now.
08 MS. CAHILL:
You might not in dry year; is that right?
09 DR. BESCHTA:
You might not in dry year. I guess it is
10 a question of what you are trying to do in this
system. If
11 you are trying to spread water around, building
multiple
12 channels is certainly a great way to do
that.
13 MS. CAHILL:
In addition to those two, are there some
14 that aren't shown on that map that are upstream
of this area
15 that you propose changes?
16 DR. BESCHTA:
There is a section upstream of the
17 Narrows, which if it was diverted out there,
would actually
18 improve the sinuosity of the stream. That
is a location.
19 If you go above
20 MS. CAHILL:
If that is one that is recommended?
21 DR. BESCHTA:
Yes.
22 MS. CAHILL:
You are agreeing with that
23 recommendation?
24 DR. BESCHTA:
The one I feel most strongly about is the
25 one I talked about this morning. These
two, I think, are
0285
01 probably not ones that I would give a high
priority at all.
02 In fact, that would be the opposite. I
think it is probably
03 not the right thing to do.
04 Above the Narrows,
the diversion there would improve
05 the sinuosity. That would have a
longterm plus. If you go
06 above the highway, there is a proposal there to
divert
07 water, also. You will grow more riparian
vegetation. It is
08 a question of which channel do you want up
there. If you
09 are going to create a new channel, it will have
essentially
10 the same length as the existing channel.
So, I don't see a
11 major gain there.
12 If you go up one
more section into where the berms are
13 at, the removal of the berms may allow some
overflow. But
14 if one is not careful, it may actually capture
the main
15 channel and actually decrease sinuosity.
16 All these little
things that one likes to talk about as
17 far as improving this and that when you rewater
channel
18 doesn't always exist. There are only a
couple locations, I
19 think, you are actually going to end up with net
20 improvement.
21 MS. CAHILL:
Perhaps Mr. Dodge was right. Perhaps,
22 maybe for clarity, let me come back to you, Mr.
Kavounas.
23 The plan, as it
was submitted, is the plan and it has
24 not been modified
25 MR.
KAVOUNAS: That's correct.
0286
01 MS. CAHILL:
by Dr. Beschta's testimony?
02 I apologize to
everyone one for that long digression.
03 Dr. Platts, let me
just ask you some very brief
04 questions.
05 The stream plan
currently says that Los Angeles will
06 consult with the Department of Fish and Game
regarding fish
07 streams.
08 Do you disagree
with that?
09 DR. PLATTS:
No, I don't disagree with that.
10 MS. CAHILL:
Are the Walker Creek of the Los Angeles
11 Walker Creek Diversion facilities a barrier to
upstream
12 passage of fish?
13 DR. PLATTS:
Yes, they are.
14 MS. CAHILL:
Are the Parker Creek diversion facilities
15 a barrier to the upstream street passage of
fish?
16 DR. PLATTS:
You are talking about the aqueduct
17 diversions?
18 MS. CAHILL:
Yes.
19 DR. PLATTS:
Yes, they are.
20 MS. CAHILL:
Is the Lee Vining diversion dam a barrier
21 to the passage of fish?
22 DR. PLATTS:
Upstream?
23 MS. CAHILL:
Yes.
24 DR. PLATTS:
Yes, it is.
25 MS. CAHILL:
Mr. Allen, with regard to the Grant Lake
0287
01 Operations and Management Plan, are there any
actual
02 operating criteria in the plan?
03 MR. ALLEN:
Specific operating criteria? No. The
04 plan contains operational guidelines. It
is difficult to
05 nail down exactly what we are going to do for
every day or
06 every week or every year. A perfect
example of this is we
07 had extremely high flows on January 3rd of this
year, where
08 we had to modify operations to accommodate these
unforseen
09 circumstances.
10 MS. CAHILL:
You've given some sample scenarios in the
11 plan. How can the parties be assured that
actual operations
12 will follow the same patterns that we see in
those samples?
13 MR.
BIRMINGHAM: I am going to object on the grounds it
14 is an argumentative question.
15 MS. CAHILL:
I can ask it another way.
16 CHAIRMAN
CAFFREY: Why don't you try another way.
17 MS. CAHILL:
Is there any commitment by LADWP in the
18 plan to following the release patterns that are
found in
19 some of the examples given?
20 MR. ALLEN:
That is the intent of the plan itself.
21 MS. CAHILL:
Given in D1631 we have particular flow
22 criteria for particular months in particular
years types,
23 do we have that in the Grant Lake Operations and
Management
24 Plan?
25 MR. ALLEN:
D1631 has specific flow requirements for
0288
01 specific year types. However, it does not
have specific
02 releases and well, it does. It splits
it up in a
03 biannual basis. DWP plan follows that same
type of logic
04 with some modifications.
05 MS. CAHILL:
Without any actual operating criteria, how
06 can the parties know how the facility will be
operated in a
07 given year time?
08 MR. ALLEN:
Well, once again, I can't even say exactly
09 how the facility will be operated, given that
there are
10 unforeseen circumstances and contingencies that
have to be
11 reacted to.
12 MS. CAHILL:
Barring a very unusual and unexpected
13 circumstance, can we conclude that in all years
where there
14 is what you call lake management water, it will
be released
15 either to add to the peak flows or to the summer
base
16 flows?
17 MR. ALLEN:
Given an ideal situation, the answer would
18 be yes, because, once again, the goal of Grant
Lake
19 Management Plan is to balance the exports with
balance
20 exports and releases with the total
runoff. And with that
21 goal in mind, there may be slight variations to
meet that
22 requirement.
23 MS. CAHILL:
In Figure 22 of your testimony, there are
24 bars that appear to indicate the sort of
bracketed
25 quantities in a given year. Like you have
for each year
0289
01 type, you give the low end of the scale and the
high end of
02 the scale.
03 Is that the next?
04 MR. ALLEN:
That is correct.
05 MS. CAHILL:
Is the upper it appears that in one of
06 your tables the upper limit of one year type
shows more
07 water than that lower limit of the next higher
year type.
08 MR. ALLEN:
In which case would this be?
09 MS. CAHILL:
I need to get my other copy.
10 Let me just go on.
11 Figure 2.2, what
lake level was assumed when this
12 figure was put together?
13 MR. ALLEN:
You are referring to my testimony, Figure 2?
14 MS. CAHILL:
Yes.
15 MR. ALLEN:
The assumption made here was that the lake
16 level is below the target elevation, which
corresponds to
17 what we commonly refer to as the transition
period.
18 MS. CAHILL:
Even within the transition period, there
19 are different lake level triggers that allow
different
20 levels of export.
21 What level of
export were you assuming here?
22 MR. ALLEN:
This level of export was between the lake
23 level of 6380 and 6392.
24 MS. CAHILL:
Why is it that in the extreme year exports
25 appear to be larger than they do, for example,
in the wet
0290
01 year?
02 MR. ALLEN:
This may take some clarification. In the
03 Grant Lake Management Plan, DWP proposed to
provide complete
04 flow conditions year round on Lee Vining,
Walker, and Parker
05 Creeks. And under 1631 the Department is
permitted to
06 export 16,000 acrefeet. In extremely wet
years, this
07 entire export would come from Rush Creek.
And therefore,
08 you have the increase in export in the extreme
years.
09 MS. CAHILL:
Now that I have this in front of me, I can
10 make better sense of my earlier question.
11 If you look at the
I guess I understand it. Never
12 mind.
13 On Page 11 of your
testimony you state that the Grant
14 Lake plan does not incorporate the ad hoc
committee flows in
15 their entirety.
16 It is true, isn't
it, they are not incorporated in dry,
17 drynormal, and the lower part of the normal
years?
18 MR. ALLEN:
That is correct.
19 MS. CAHILL:
Dr. Trush, do you have some opinion as to
20 whether leaving out those years will hinder
achieving those
21 indices that you will be looking for in order to
determine
22 whether the streams are being restored?
23 DR. TRUSH:
We gave that a lot of thought. After the
24 February 3rd or 13th, we had a memo regarding
the ad hoc
25 committee. We were contacted by L.A. a few
times after the
0291
01 memo, and particularly with reference to the
hundred cfs
02 during the dry year. And we couldn't come
up with a
03 geomorphic rationale for the hundred.
04 I suspect it's got
its value, but we couldn't come up
05 with it. And again, thinking about us
sitting here, going,
06 "Why did you want a hundred?" We
couldn't come up with a
07 good one, a reason for it. So we were
willing to back off
08 on that, the idea that during the monitoring we
could take a
09 closer look at some of these lower flows and
what they might
10 do. We just simply can't anticipate.
11 I suspect there is
an effect, but I really can't give
12 you one. So, in other words, when L.A.
reduced some of
13 those flows from our earlier recommendation, we
did have
14 some say in letting them do that. They did
contact us.
15 That is to say, that was done. I think I
wrote that in my
16 testimony. So, anyway, we had no good
reason for that low
17 flow peak.
18 MS. CAHILL:
Let me wade once again into monitoring,
19 see if I can understand what it is that you are
proposing in
20 the Monitoring Plan. The first book, which
is White Book,
21 basically, is the scope of the data to be taken;
is that
22 right?
23 DR. TRUSH:
Yes.
24 MS. CAHILL:
It is intended to be almost in the level
25 of detail that Los Angeles could find a
contractor and say,
0292
01 "Go do this for us"; is that us
right?
02 MR.
KAVOUNAS: Yes, that is correct.
03 MS. CAHILL:
And then the Blue Book is an attempt, is
04 it, to make sense of the data that you are
gathering in the
05 White Book. Is that right?
06 MR.
KAVOUNAS: That is correct.
07 MS. CAHILL:
And some of the experiments with painted
08 rocks, Dr. Trush, could you explain what it is
you hope to
09 learn from those measures?
10 DR. TRUSH:
One of the attributes is that the channel
11 bed, the overall channel bed, in alluvial rivers
in general
12 are mobilized on the average once a year, maybe
every other
13 year on spring fed streams or snow melt streams
like this,
14 but certainly frequently. So, in order to
do that you can
15 whip out some equations, which I never trust,
but always do
16 them. And then I go and I put marked rocks
in to see how
17 far off they are.
18 And what we do, we
try to simulate the beds as best we
19 can by painting a series of rocks, putting them
out there.
20 Then afterwards we simply record how many moved
downstream.
21 Generally more than a meter downstream.
Sometimes a rock
22 can adjust a little bit and it is not true
movement.
23 We then try to
narrow a window with enough floods. We
24 create a graph where we've got on the Y
Axis we have
25 percent rocks moved. On the X Axis we have
flood. And we
0293
01 realize that at low flood peaks we have almost
no rocks
02 moving, and after a certain real high flood peak
everything
03 is down in China.
04 And so, there is a
window of flows there where we know
05 we are reaching incipient conditions. I
can then adjust the
06 equations so there is some constants in there to
make a
07 better prediction of what stage height, given a
certain
08 flow, will mobilize the channel bed
surface. We then can
09 convert that stage height into a
discharge. That is how we
10 make our recommendation for an incipient motion
of the
11 channel bed, which is one of the tributes.
12 MS. CAHILL:
So, there is some level of incipient
13 motion that is the desired level?
14 DR. TRUSH:
No. That is why we go in at it from both
15 sides, from no mobility and totality
mobility. There is a
16 scatter in there. When we look at the
force that moves a
17 rock in the bed, it is an average. In
fact, the shear
18 stress range almost two standard deviations,
easily.
19 MS. CAHILL:
My question, I guess, is what the linkage
20 is. Once you've gone and you know what
flows you had and
21 you know what size of rock moved how far, then
how do you
22 work back to determining what the flows are that
you need to
23 get restoration?
24 DR. TRUSH:
Well, we want to be able to we define a
25 low and a high end flow that brackets incipient
conditions.
0294
01 So we are fairly sure that it is between this
flow and this
02 flow.
03 BOARD MEMBER
BROWN: It is nonlinear or is it a linear?
04 DR. TRUSH:
It is nonlinear. There is a standard track
05 of force equation. I think I have it
somewhere in the
06 testimony. There is a coefficient that you
can adjust.
07 Typically, we use .03 to .045. In the
simple experiments
08 that I did on the Lee Vining Creek, those
numbers held
09 true.
10 MS. CAHILL:
Simplify for me, once you let's say you
11 have a given number of years. The plan
says three to five
12 years. Is three to five years, given a
variety of year
13 types, long enough to make some meaningful
conclusions or is
14 it going to be a longer time than that?
15 DR. TRUSH: I
would like around eight, but I think,
16 depending on a good selection of years, five
could do it.
17 MS. CAHILL:
So, in five to eight years, when you had a
18 variety of flows, you've done the marked rock
experiment for
19 a number of years, you now have some flows that
bracket the
20 upper and lower end of what you would like to
see. Then
21 what is the link back to when you bracket
that, is the
22 low one one that you would expect to see in dry
type years
23 and the high one one you would expect to see in
wet years?
24 Would you come up
with some recommendations for flows
25 by year type?
0295
01 What would be the
practical way of taking that
02 knowledge and implementing it on the stream?
03 DR. TRUSH:
Depends on how narrow that window can be
04 defined. I am doing it right now on
several other streams
05 in the North Coast, and we are getting pretty
narrow
06 windows. The median and the mean of the
flows in that
07 aren't too far off from one another.
08 My first shot at
it would be taking the mean value
09 inside that window and saying that in alluvial
stream
10 channels we generally reach that in peak
conditions on the
11 average once a year. That would be my flow
that I would
12 target, on the average once a year.
13 Now, we did that
analysis, talk about it here, on the
14 historic Rush Creek channel. We went into
a section of
15 channel that was bending. We took the
particle distribution
16 on bed and, using our tractive force equation,
we predicted
17 how deep the flow would have to be to mobilize
that bed.
18 And when we did that and converted that to cfs,
that depth,
19 it came out to just under the twoyear flood
predisturbance.
20 That was wonderful connection that this stream
was working
21 alluvially earlier on. That gave us a lot
of that ammo, in
22 our mind, the confidence to say that, yes, these
criteria
23 make sense.
24 So, I've got those
calculations somewhere. If we had
25 time or whatever, I could go through how we did
that
0296
01 exactly.
02 MS. CAHILL:
What I am trying to get at is the linkage
03 Mr. RoosCollins was trying to get at it.
Once you have
04 this data, does this plan indicate how it gets
translated
05 into flows up or down? Mr. Kavounas has
committed that if
06 there is evidence there, Los Angeles will do
what it takes.
07 But how do we tell them what it takes and how do
the other
08 parties how are we assured that this
happens?
09 DR. TRUSH:
For example, if we are estimating that on
10 straighter reaches, in a two or three channel
width long,
11 that reaching an incipient condition to meet a
tribute 4 at
12 about 400, 420 cfs, based on our equation, we
then go back
13 and find that between 350 and 400 we are getting
80 percent
14 of the incipient condition. Then I would
feel pretty good
15 about going down 50 or 80 cfs; that we would
then make it.
16 MS. CAHILL:
In all year types or in certain year
17 types?
18 DR. TRUSH:
It is independent of year type. We are
19 looking at the characteristic, the mobility of
the bed, and
20 the flow that interacts with that. We then
go back to the
21 frequency and then identify those, in that we
look for the
22 twoyear, the oneandahalf year flood.
23 And if it still
jives, that is what we would recommend,
24 that we would go down. If we estimated 420
at 50 percent
25 and more of rocks only started moving at 450 to
500, it goes
0297
01 up.
02 MS. CAHILL:
You are not going to ask for this one
03 level in every year type, are you? Aren't
you still relying
04 on variability?
05 DR. TRUSH:
That is because you, so far, only discussed
06 one of the attributes. There are other
attributes that have
07 other thresholds in them. The channel bed
doesn't work just
08 simply by mobilizing its surface every now and
then. You've
09 got to reshape bars, and you've got to build a
floodplain.
10 Those take other flows. So, the Monitoring
Plan would
11 identify those in a very similar way to the
marked rock.
12 So, we would be
looking at what it takes to do a deep
13 scour and mobilization, which really rejuvenates
the
14 riparian on point bars, those sorts of things,
and the
15 inundation of the floodplain. It would be
other ones that
16 we would do.
17 MS. CAHILL:
I just asked with regard to the White
18 Book, whether it would simply go out to a
contractor in the
19 form it is? Could the Blue Book go out to
a contractor in
20 the form it's in, or would considerable,
additional
21 direction be required?
22 DR. TRUSH: I
would say there is only a few folks that
23 I would trust doing it. We just had it bid
on another
24 project, and it is doing it would have to
be a close
25 watch.
0298
01 MS. CAHILL:
You indicated that the reaches that were
02 selected for sampling, you called them
representative
03 reaches.
04 Can you tell us
what each one of them does represent,
05 were they chosen to be representative of a
particular type
06 of condition other than just the alluvial stream
that you
07 mentioned?
08 DR. TRUSH:
The lower ones on Rush Creek, one was more
09 singular. Another one was more of a dual
channel. There
10 wasn't a whole lot distinguishing them.
Other than we had a
11 past history of some good crosssections we
could take
12 advantage of. What we realized, that that
wouldn't be
13 satisfactory for everybody to look simply below
the Narrows.
14 So, we identified another reach higher up, above
the 395.
15 It is a very different channel morphology.
16 MS. CAHILL:
Given that the original scientists' flows
17 are not proposed to be provided in the L.A.
plan, would it
18 make sense to add an additional reach above the
Narrows to,
19 in fact, determine what effect flows up there
are having,
20 for example, between the Narrows and 395?
21 DR. TRUSH: I
don't see it between the Narrows and
22 395. If I would add another reach, I would
identify
23 something above 395 where our recommend reach
is. From 395
24 down to where Parker comes in, it is a very
nonerodable
25 bank, fairly steep, fairly stable channel.
You are not
0299
01 going to learn a whole lot from that.
02 Again, what we are
really after are those bottomlands
03 restoring. That is why we focussed on
that.
04 MS. CAHILL:
I am not sure who this is for, the whole
05 concept of the fish sampling by
snorkeling. And there is
06 now the indication that you will calibrate by
07 electrofishing.
08 Is that you, Mr.
Hunter?
09 MR. HUNTER:
I suppose.
10 MS. CAHILL:
Why not simply do electrofishing in the
11 place, first?
12 MR. HUNTER:
I think that the Department would prefer
13 to use snorkeling, given concerns about
electrofishing
14 damage to trout. It doesn't work. We
have response to
15 comments that we received. We have
included the
16 electrofishing if snorkeling doesn't work.
17 MS. CAHILL:
Let me just ask one quick question of Dr.
18 Kauffman.
19 Those pie charts
we saw today, what stretch of the
20 creek was covered?
21 DR.
KAUFFMAN: From the dam on Grant Lake to the mouth
22 of the Mono lake.
23 MS. CAHILL:
The entire
24 DR.
KAUFFMAN: The entire stream; that's
correct.
25 MS. CAHILL:
Thank you very much.
0300
01 CHAIRMAN
CAFFREY: Thank you, Ms. Cahill.
02
(Reporter changes paper.)
03 CHAIRMAN
CAFFREY: We are ready to resume. Paper is
04 loaded.
05 Let's take a
moment now to talk a little bit about what
06 we are going to do tonight. I had a little
consultation
07 with Mr. Frink, tried to do some time
estimations.
08 Mr. Birmingham, I
presume you are going to need some
09 time for redirect.
10 MR.
BIRMINGHAM: Yes, I will.
11 CHAIRMAN
CAFFREY: Why don't you, then, let your
12 panelists who are here just waiting for the
waterfowl panel
13 go, and we will get to them tomorrow.
14 I am sorry.
Ms. Scoonover, were you
15 MS.
SCOONOVER: I want to remind you that I have a few
16 questions for crossexamination of this panel.
17 CHAIRMAN
CAFFREY: I have not overlooked you at all.
18 We are still rolling along here.
19 In deference to
those folks, I just wanted to say as
20 early as we could, in deference to those who are
waiting,
21 that it looks pretty much like an impossibility
now that we
22 would get to them tonight. I wanted to
give Mr. Birmingham
23 the opportunity to relieve them for the
night.
24 You want to do
that then? Do you have something else,
25 Mr. Birmingham?
0301
01 MR.
BIRMINGHAM: The only other comment, I would like
02 to
03 CHAIRMAN
CAFFREY: I am sorry, I can't hear Mr.
04 Birmingham. Could you please hold it down
in the audience?
05 I am sorry,
sir. Go ahead.
06 MR.
BIRMINGHAM: The only other point I would make is
07 that some members of this panel have teaching
responsibility
08 tomorrow. And if we can finish this panel
tonight, that
09 would be very, very helpful.
10 CHAIRMAN
CAFFREY: That is what I am trying very much
11 to do, although that depends on how many
questions you have
12 to ask them, as well. We can reach a point
up here at this
13 dais, and then all the parties, as well, get
rummy. It's
14 been a long day.
15 I think that is an
admirable goal. I would sure like
16 to accomplish it tonight, if we can. It
depends on how many
17 questions people have, so let's get to it.
18 MR. MOONEY:
We were outside.
19 CHAIRMAN
CAFFREY: You didn't hear the announcement. I
20 just was telling Mr. Birmingham that he could
let the
21 panelists go who were going to be participating
in the
22 waterfowl panel because we won't be getting to
them until
23 tomorrow. When you take a look at the fact
that we still
24 have questions from staff, questions from the
Board, and we
25 still, of course, have to hear
crossexamination from Ms.
0302
01 Scoonover, and we have redirect and
recross.
02 So, we are going
to try to get through all that
03 tonight. I doubt that we will even have
the slightly
04 plausibility of ever getting to the waterfowl
folks. We are
05 letting them go.
06 MR. MOONEY:
And then reconvene at 9:00 a.m.?
07 CHAIRMAN
CAFFREY: We will reconvene at 9:00 a.m.
08 I believe that
gets us to you, finally, Ms. Scoonover.
09 Thank you so very much for your patience.
10 We are all
ready.
11 MS.
SCOONOVER: Thank you.
12 CHAIRMAN
CAFFREY: Please proceed, Ms.
Scoonover.
13 MS.
SCOONOVER: Thank you, Mr. Chairman.
14
oOo

CROSSEXAMINATION
16
BY STATE LANDS COMMISSION AND
17
DEPARTMENT OF PARKS AND RECREATION
18
BY MS. SCOONOVER
19 MS.
SCOONOVER: I actually do not have questions on
20 stream monitoring. So those of you who
have stream
21 monitoring responsibilities, feel free.
22 Dr. Kauffman, in
your written testimony and then your
23 summation earlier, you talked specifically about
benefits to
24 riparian vegetation of both rewatering and
eliminating
25 grazing?
0303
01 DR.
KAUFFMAN: Yes.
02 MS.
SCOONOVER: Those, would you say, are two of the
03 most important factors for the restoration, the
riparian
04 restoration, that we have seen along Rush and
Lee Vining
05 Creeks?
06 DR.
KAUFFMAN: Undoubtedly.
07 MS.
SCOONOVER: Is it significant whether the water is
08 surface flow or groundwater?
09 DR.
KAUFFMAN: Yes. They are going to have
different
10 influences. Surface water, during peak
flows, creating
11 gravel bars, channel confinement similar to the
processes
12 that Bill has outlined, is responsible for the
creation of
13 gravel bars, new floodplain areas where
cottonwwood, willows
14 establish.
15 The surface,
hyporheic flows is where we see the
16 reformation of wetland type communities, the
Carex, the
17 sedge meadows, the wet meadow and dry meadow
vegetation.
18 MS.
SCOONOVER: With the increase in groundwater
19 levels, you would expect to see also an increase
in
20 vegetation dependent upon groundwater
levels?
21 DR.
KAUFFMAN: Yes.
22 MS.
SCOONOVER: So a succession from xeric to riparian
23 or wetlandtype vegetation; is that correct?
24 MR.
KAUFFMAN: Yes.
25 MS.
SCOONOVER: I had a question about an exhibit.
0304
01 Mr. Tillemans, I
believe the exhibits are yours, so I
02 will ask you identify it. It is DWP
Exhibit 42. You
03 referred to it earlier. I think Steve
pulled it out of the
04 pile.
05 Specifically, on
DWP Exhibit 42, specifically the
06 panoramic photo on the bottom, can you orient
us, Mr.
07 Tillemans, what it is we are looking at?
08 MR.
TILLEMANS: This is taken on the east side of Rush
09 Creek on the bottomlands. It is below the
Narrows, and it
10 is a panoramic where I am attempting to get in
the vicinity
11 of the Narrows, including all the way down to,
probably, the
12 bottom end of Channel 10 where it presently
comes in.
13 MS.
SCOONOVER: Dr. Kauffman, can you identify the type
14 of vegetation in the foreground, just
predominant type of
15 vegetation?
16 DR.
KAUFFMAN: The vast majority is sagebrush and
17 bitterbrush.
18 MS.
SCOONOVER: Without some change in water
19 availability, either surface or groundwater, do
you expect
20 that this vegetation pattern will change?
21 DR.
KAUFFMAN: No.
22 MR.
TILLEMANS: If you take a look at this picture, I
23 am up on the bluff and way above the present
water table.
24 So that is why we have to clarify where the spot
was taken
25 because you are talking several 10, 20 feet
above the
0305
01 original creek bed.
02 MS.
SCOONOVER: Thank you.
03 So, Dr. Kauffman,
your testimony was that you don't
04 expect any significant change in either the
nature or
05 extent of vegetation without some drastic change
in water
06 availability?
07 DR.
KAUFFMAN: Without some change in availability,
08 yeah, the upland vegetation would remain upland
vegetation.
09 MS.
SCOONOVER: I would like to move to DWP Exhibit
10 Number 51. Part of the problem, Mr.
Tillemans, and I
11 appreciate your indulgence, is that the copies
we got are
12 very small. It is difficult to orient and
identify.
13 Can you tell me,
Mr. Tillemans, where these photos,
14 these series of photos, were taken?
15 MR. TILLEMANS: In
the Channel 10 rewatering site.
16 MS.
SCOONOVER: Dr. Kauffman, the top three photos
17 seem to indicate, or seem to show, a significant
amount of
18 dead vegetation.
19 DR.
KAUFFMAN: Uhhuh.
20 MS.
SCOONOVER: Can you identify the type of
21 vegetation, or do you have a guess on what the
kind of
22 vegetation was? If not, that is all right,
too.
23 DR.
KAUFFMAN: The majority of it is dead willows.
24 MS.
SCOONOVER: Are you familiar with this
stretch?
25 DR.
KAUFFMAN: Yes.
0306
01 MS.
SCOONOVER: Have you seen this stretch?
02 DR.
KAUFFMAN: Yes.
03 MS.
SCOONOVER: Would you expect, if this section were
04 rewatered, that the willows, in fact, would
regenerate here?
05 MR.
BIRMINGHAM: Completely misstates the
testimony.
06 This section was rewatered; that is what Dr.
Kauffman has
07 said resulted in this condition.
08 MS.
SCOONOVER: I believe, with all due respect to Mr.
09 Birmingham, Dr. Kauffman has just testified that
there are a
10 number of there is evidence of dead
vegetation, dead
11 willows in the top three photographs.
12 DR.
KAUFFMAN: Yes, I did. That was mostly a
lot of
13 that is destroyed vegetation from the actual
equipment and
14 rewatering of this area.
15 MS.
SCOONOVER: And again, I ask the question: If
16 water were returned to this area, where the dead
vegetation
17 is, would you expect vegetation of this nature
or similar
18 vegetation to be reestablished?
19 DR.
KAUFFMAN: May I go to one of examples that I
20 looked at this morning to answer your question?
21 MS.
SCOONOVER: Certainly.
22 DR.
KAUFFMAN: This is the site that we are referring
23 to from another angle. This is Exhibit
Number 49. The area
24 that the the willows that are established
there, that you
25 see in the photo, that you brought up,
established prior to
0307
01 the act of restoration or the act of channel
rewatering
02 process. At that point in time, my
contention is, that
03 through the digging of the new channel, we have
lowered the
04 water table at this upper end.
05 If you look at the
lower end, where you are seeing more
06 water, you would see a wetter composition start
to occur.
07 But at this point, we are higher and dryer than
probably we
08 were before the restoration or the act of
manipulation, at
09 this point.
10 MS.
SCOONOVER: Dr. Kauffman, using the previous
11 photos, that would be DWP Exhibit 51, for
illustrative
12 purposes only, granting that your testimony this
morning was
13 of a slightly different nature, the question I
am asking is:
14 If there were adequate moisture return, either
through
15 surface flows or combination of surface and
groundwater,
16 would you expect riparian vegetation to become
reestablished?
17 DR.
KAUFFMAN: Yes. However, it is impossible for
that
18 site.
19 MS.
SCOONOVER: Illustrative purposes only?
20 DR.
KAUFFMAN: Yes.
21 MS.
SCOONOVER: You testified this morning there were
22 ample amounts of seed occurring in the
area.
23 On what do you
base that conclusion?
24 DR.
KAUFFMAN: Personal observation.
25 MS.
SCOONOVER: Is that perhaps because that
0308
01 historically these areas had riparian
vegetation? Is that
02 part of your personal observation?
03 DR.
KAUFFMAN: It is quite remarkable. If you
would
04 look at the previous work by Julia Stromberg and
Duncan
05 Patton in 1987, very good riparian ecologists,
who did the
06 early vegetation maps of the site, one of the
things they
07 spoke of is that there seemed to be a lack of
vegetation
08 reproduction on this site. And one of the
hypotheses they
09 set forth is, we have no idea when reproduction
will occur
10 again.
11 I think it is a
wonderful advancement on our
12 understanding of science that through rewatering
we do see
13 really quite dramatic and remarkable rates of
willow and
14 cottonwood reproduction this year.
15 MS.
SCOONOVER: Is it primarily, Dr. Kauffman, because
16 rewatering is occurring and in an historic
channel where
17 there is seed available because there were
riparian plants
18 there previous? Is the seed coming from
some other area or
19 is the seed present?
20 DR.
KAUFFMAN: The seeds are coming from onsite.
We
21 certainly noticed a number of plants reproducing
and
22 producing seed.
23 MS.
SCOONOVER: Is that unusual for this portion of the
24 Eastern Sierra of the Mono Basin?
25 DR.
KAUFFMAN: Again, the best evidence that I have
0309
01 would be reading the data of Stromberg and
Patton, and they
02 talk about a lack of it in 1987 and an abundance
of it
03 today. So, where one would have mature
vegetation, one
04 would see the sort of seeding.
05 MS.
SCOONOVER: Dr. Kauffman, I would like to now look
06 at DWP Exhibit Number 63.
07 This is a series
of photos showing Rush Creek beginning
08 in July of 1986 and concluding in August of
1995.
09 Dr. Kauffman, you
testified earlier that over this
10 nineyear period there was a marked and
noticeable growth in
11 riparian vegetation. Is that accurate?
12 DR.
KAUFFMAN: Yes.
13 MS.
SCOONOVER: That would be over a nineyear period,
14 correct?
15 DR.
KAUFFMAN: Yes.
16 MS.
SCOONOVER: Would you say that is apparent there is
17 a marked and noticeable growth in riparian
vegetation in,
18 say, the first five years from July of '86 to
October of
19 '91?
20 DR.
KAUFFMAN: There is yes. Well, yes.
You can
21 see there is a difference in this photo.
22 MS.
SCOONOVER: I assume then that your answer would be
23 the same for in seven years as well, the
intermediate
24 picture, July 1986 to September 1993, a marked
and
25 noticeable growth in riparian vegetation?
0310
01 DR.
KAUFFMAN: Yes.
02 MS.
SCOONOVER: Dr. Beschta, you are familiar with the
03 Rush Creek bottomland area, aren't you?
04 DR. BESCHTA:
Yes.
05 MS.
SCOONOVER: You testified previously about historic
06 channels and changes in land forming in those
historic
07 channels, have you not?
08 DR. BESCHTA:
I have had testimony regarding the
09 bottomland channels.
10 MS.
SCOONOVER: Can you tell me what reach of the
11 bottomland channel these pictures are taken
from?
12 DR. BESCHTA:
The numbering system?
13 MS.
SCOONOVER: Would be that Reach 5?
14 DR. BESCHTA:
Let me pull a map.
15 It is below the
ford and above the County Road. It is
16 in Reach 5A, according to what I've got here.
17 MS.
SCOONOVER: Can you identify, Dr. Beschta, the land
18 form in the background of these photos, in any
of these
19 photos?
20 DR. BESCHTA:
The land form up here?
21 MS.
SCOONOVER: Yes.
22 DR. BESCHTA:
I believe that is deltaic deposit from
23 ancient Mono Lake system. So, those are
laid down gravels
24 from sometime ago.
25 MS.
SCOONOVER: This is not, for example, a stranded
0311
01 stream channel or an example of an
incision?
02 DR. BESCHTA:
This is an example of an incision taking
03 place over geologic time, yes. The
bottomlands are now at a
04 much lower elevation than this previous
surface.
05 MS.
SCOONOVER: Five to twentyeight feet lower,
for
06
example?
07 DR. BESCHTA:
Yes.
08 MS.
SCOONOVER: So, prediversion or preincision, Rush
09 Creek would have been on top of that plateau
feature that
10 you indicated in Exhibit 63, then?
11 DR. BESCHTA:
I don't believe so.
12 MS.
SCOONOVER: Where would Rush Creek have flowed?
13 DR. BESCHTA:
I think Rush Creek, and I wasn't here,
14 but looking at aerial photographs, you have had
incision
15 from the lake all the way up to the about the
ford. It
16 looks like it would probably be in the
neighborhood of maybe
17 ten feet or something like that, maybe, depends
on where you
18 are at. Deeper as you got towards the
lake, but up here, I
19 guess, you would probably not exceed ten feet of
incision.
20 MS.
SCOONOVER: In response to a question from Mr.
21 RoosCollins, you described the entire Rush
Creek system as
22 degraded.
23 Is that
accurate?
24 DR. BESCHTA:
Historically, yes. I mean, prior to
25 1986, let's say, '86, '87.
0312
01 MS.
SCOONOVER: By degraded do you mean wider,
02 straight, steeper and generally less complex
physically and
03 biologically?
04 MR.
BIRMINGHAM: Compound. I will object as
compound.
05 CHAIRMAN
CAFFREY: Want to break it down a little bit.
06 MS.
SCOONOVER: Certainly. I've got an hour.
07 BOARD MEMBER
BROWN: Fortysix minutes.
08 MS.
SCOONOVER: I will rephrase the question.
09 And by degraded,
Dr. Beschta, do you mean, for example,
10 that the channel is wider than historic?
11 DR. BESCHTA:
That is one component of degradation.
12 MS.
SCOONOVER: Is it straighter than historic?
13 DR. BESCHTA:
It lost major sinuosity.
14 MS.
SCOONOVER: Is it deeper than historic?
15 DR. BESCHTA:
If you lose sinuosity over the same
16 elevation change, it now has a steeper
gradient.
17 MS.
SCOONOVER: Is it generally less physically
18 complex?
19 DR. BESCHTA:
Physically less complex in some ways;
20 that is, you would not have had welldefined
channel. You
21 might have had multiple channels pushing across
the bottom.
22 MS.
SCOONOVER: Is it less biologically complex?
23 DR. BESCHTA:
Under the degraded condition? That is
24 the question?
25 MS.
SCOONOVER: That is the question.
0313
01 DR. BESCHTA:
Yes, it would have been biologically
02 complex. That is a major component of the
degradation.
03 MS.
SCOONOVER: Dr. Beschta, with the drop of or
04 incision of the creek, would there also be a
drop in the
05 groundwater levels associated with the creek?
06 DR. BESCHTA:
You raise an interesting question. It
07 would be interesting to see what ultimately the
monitoring
08 data will tell us regarding groundwater.
As the system has
09 rewatered over the last ten years, or perhaps
longer, it is
10 obviously, at least in my opinion, getting
wetter. You get
11 subsurface flows slowing up in various
places. Local
12 incision could lower the groundwater, but it may
recover
13 through time, as you have water back in the
system.
14 It is not a
twodimensional channel, and it is not a
15 twodimensional system with regard to where the
water is
16 coming in. The water is coming from
upgradient, and it
17 could be moving down through the alluvium and be
showing up
18 in various ways.
19 So, as the lake
comes up, that will also change
20 groundwater conditions, at least closer to the
lake. So,
21 the groundwater dynamics would be a very
interesting
22 component of what is going on.
23 What I see is, I
see more water in subsurface
24 environment showing up and being expressed in
vegetation.
25 MS.
SCOONOVER: The stream channel that is shown in
0314
01 DWP Exhibit 63, would you say, Dr. Beschta, it
is narrower
02 than historically?
03 DR. BESCHTA:
Is it narrower than in August of '95 than
04 it was historically, yes.
05 MS.
SCOONOVER: Dr. Beschta, I would like to show you
06 some photographs that were previously entered
into the
07 record by the National Audubon Society and the
Mono Lake
08 Committee, twice as a matter of fact. They
were entered as
09 exhibits, and accepted as exhibits, during the
previous
10 hearing, and they are numbered NAS&MLC
Exhibits 205 through
11 208.
12 DR. BESCHTA:
Okay.
13 MS.
SCOONOVER: In addition, it was entered into an
14 exhibit as part of a report, NAS&MLC Number
137. Those are
15 the pictures that I will show you, Pages 724
and 726,
16 showing historic comparisons, historic and
current day
17 comparisons of Rush Creek in about this same
vicinity.
18 I would like you,
Dr. Beschta, to describe the
19 pictures, the historical pictures, shown both
the two pages
20 that I have identified, those would be the top
pictures in
21 NAS&MLC Exhibit 137.
22 DR. BESCHTA:
The top two pictures on both pages?
23 MS.
SCOONOVER: Yes. What kind of habitat would
you
24 say?
25 DR. BESCHTA:
They are showing ponded habitat. Looks
0315
01 like it could be the originals are much
better than
02 these. Looks like you've watercress or
some aquatic
03 vegetation growing in the pond. This is
not a flowing
04 environment from the standpoint of a Rush Creek
channel. I
05 believe I know where these pictures are
taken.
06 MS.
SCOONOVER: Would that be in the Rush Creek Channel
07 5 area?
08 DR. BESCHTA:
It is immediately above the County Road.
09 Let me make sure I tell you the right
channel.
10 Yes, it would be
the in 5, Rush Creek Channel 5.
11 MS.
SCOONOVER: Which is also the area we are looking
12 at in DWP Exhibit Number 63?
13 DR. BESCHTA:
This is further upstream. This is not
14 the same location.
15 MS.
SCOONOVER: But they both are within Reach 5 of
16 Rush Creek?
17 DR. BESCHTA:
That doesn't mean they are close to
18 looking the same.
19 MS.
SCOONOVER: Fine.
20 I would direct
your attention then to the lower
21 pictures.
22 DR. BESCHTA:
Yes.
23 MS.
SCOONOVER: And ask you to describe what you see in
24 the lower pictures on both pages.
25 DR. BESCHTA:
The lower picture on the first page,
0316
01 which is Page 724, is a much more xeric
site. If this is
02 from the same location, you have lost the hard
woods here
03 that are showing up, and the stream is some
distance away
04 from this particular location. It probably
wasn't in 1934
05 also.
06 With regard to the
second page, again, the top picture
07 is of ponded water. The bottom picture
appears to be from a
08 similar orientation, based on the hills in the
background,
09 but I am not familiar with this picture nor,
necessarily,
10 have I been to this location.
11 MS.
SCOONOVER: Dr. Beschta, does it also exhibit a
12 drier habitat?
13 DR. BESCHTA:
It is much drier today.
14 MS.
SCOONOVER: There is no standing water?
15 DR. BESCHTA:
There is no standing water; that's
16 right.
17 MS.
SCOONOVER: Thank you.
18 Dr. Trush, are you
familiar with the stretch of river
19 described in, or stretch of Rush Creek described
in DWP
20 Exhibit 63?
21 DR. TRUSH:
Yes.
22 MS.
SCOONOVER: Would you agree with Dr. Beschta that
23 the stream, that the feature in the far ground,
identified
24 by Dr. Beschta, is a historic stream channel
prior to
25 incision or some other feature?
0317
01 DR. TRUSH:
Being familiar with the site and assessing
02 what it was historically, it is, really, two
different
03 things. But I have nothing to lead me to
believe that it is
04 not.
05 MS.
SCOONOVER: Do you, Dr. Trush, believe that, with
06 what you know of this stretch of creek, that
there has been
07 a significant change in the habitat from this
point, present
08 point, which would be the August 1995 picture in
DWP Exhibit
09 63, and prediversion conditions?
10 DR. TRUSH:
So you're talking the '30s?
11 MS.
SCOONOVER: Correct.
12 DR. TRUSH:
It would be a hard call for me. I can't
13 really say how much riparian was down along the
edge there
14 at the time, but I would have to look. I
am not sure how
15 confined this part of the channel was in
pre41.
16 MS.
SCOONOVER: Dr. Trush, if you assumed anywhere
17 from a 10 to 20 foot incision on this reach of
the creek,
18 would you assume that that would have a
significant and
19 noticeable impact on the environment?
20 DR. TRUSH:
That would be my first hypothesis.
21 MS.
SCOONOVER: Is DWP Restoration Plan going to be
22 able to remedy or restore this stretch of stream
to
23 prediversion quality, prediversion
standard?
24 DR. TRUSH:
My guess is not. That with that amount of
25 incision you are going to strand the areas that
used to be
0318
01 more riparian. Very little chance of
getting groundwater to
02 keep them going.
03 I don't see a
whole lot you can do about it, given the
04 depth of the incision. With the rise of
the lake, we are
05 going to start getting more adjustments.
There might be a
06 backwater, groundwater effect. With that
amount of incision
07 you are going to leave some areas in stress.
08 MS.
SCOONOVER: Is there anyone on the panel who
09 disagrees with that point? Is there anyone
who believes
10 that the DWP plan will, indeed, restore this
stretch of
11 Rush Creek to pre41 condition?
12 DR.
BESCHTA: I think functionally it will restore it
13 to something better than you had in 1941.
They were
14 diverting water pre1941 in this reach and
creating those
15 offchannel ponds in those areas over
there.
16 So, that will not
longer occur in the current plan, and
17 the recover of the riparian vegetation will give
you plant
18 communities along this stream equivalent, as
good as, or
19 better than what you had pre1941.
20 MS.
SCOONOVER: Dr. Beschta, would that be your
21 testimony if, indeed, the incision in this
stretch was 15 to
22 28 feet?
23 DR. BESCHTA:
If you are trying to recreate the
24 geomorphic surfaces, you can't put that back,
and I agree
25 with Bill on that. You cannot go back to
that condition.
0319
01 But you are asking, "Can we recover the
channel and its
02 riparian communities to pre1941
conditions," and I would
03 suggest, yes. In fact, not suggest, I
would come to the
04 conclusion, based on what I know, that you can
recover this
05 system back to pre1941 conditions, and better,
from an
06 ecological standpoint.
07 MS.
SCOONOVER: Of the same area?
08 DR. BESCHTA:
Of the same reach, Reach 5.
09 MS.
SCOONOVER: Would it be comparable, say, in terms
10 of acreage?
11 DR. BESCHTA:
Probably not in terms of overall acreage
12 because, again, you have incised the
system. You may have
13 left terraces hanging up at higher surfaces, ten
feet, five
14 whatever they are, which will not be rewatered
under current
15 conditions.
16 MS.
SCOONOVER: Dr. Kauffman, can you, under the DWP
17 plan, reestablish riparian vegetation on the
stranded
18 terraces that Dr. Beschta described?
19 DR.
KAUFFMAN: No. Again, what one would look at
in
20 terms of restoration is that, due to the extreme
geomorphic
21 change, you have created a whole new ecosystem
equilibrium,
22 a whole new potential natural community.
We are not getting
23 back that terrace floodplain complex in 1941, in
any time
24 soon. Simply not a feasible human
endeavor.
25 We can recover the
ecosystem based on the current
0320
01 geophysical, hydrological vegetation
equilibrium.
02 MS.
SCOONOVER: Thank you.
03 Dr. Platts, in
your written testimony you stated that
04 the plan, the DWP plan, was generally consistent
with
05 D1631. And in your oral comments this
morning, you said
06 that this plan was generally adequate. To
my untrained ear,
07 this sounds like a less than resounding
endorsement of the
08 DWP plan.
09 My question for
you is: Is this just scientific
10 caution or do you have professional reservations
concerning
11 either the plan or the Monitoring Plan that has
been
12 proposed?
13 DR. PLATTS:
It is scientific caution because the
14 success of the rehab program is going to depend
on the
15 monitoring program and the evaluation package
put upon the
16 monitoring program.
17 So, I use the term
"general" because other things have
18 to come into play to make this a success.
19 MS.
SCOONOVER: Do I infer from that, Dr. Platts, the
20 plan and the Monitoring Plan, the Stream
Restoration Plan,
21 including the Monitoring Plan, in your
estimation is an
22 adequate plan and is consistent with the
requirements of
23 stream restoration as they have been defined
previously by
24 this panel?
25 DR. PLATTS:
Yes, the two of them together.
0321
01 MS.
SCOONOVER: That is all.
02 CHAIRMAN
CAFFREY: Thank you, Ms. Scoonover.
03 That completes the
crossexamination from the parties.
04 We will now move to crossexamination from
Board staff.
05 MR. JOHNS:
Just a very few questions.
06 CHAIRMAN
CAFFREY: Mr. Johns.
07
oOo
08
CROSSEXAMINATION
09
BY BOARD STAFF
10 MR. JOHNS:
Referring specifically to the Monitoring
11 Plann. Dr. Trush, I got the sense of what
you are trying to
12 tell us, you were generally in agreement with
the
13 monitoring plan, as set forth in Exhibits 22 and
23, to stay
14 in place until you have data that indicated
there was an
15 ecologic change.
16 Is that a good
summary of your testimony?
17 DR. TRUSH:
Whether we would change the Monitoring
18 Plan?
19 MR. JOHNS:
Right.
20 DR. TRUSH:
As well as any sort of adaptive management.
21 Yeah, and that
related to trying to get a handle on
22 duration effects, particularly. In the
next few years we
23 will have a better understanding of what we are
dealing with
24 to come up with a hybrid plan for coming up with
how to
25 measure.
0322
01 MR. JOHNS:
The plan as set forth now would be
02 something we'd want to keep in place until we
have data to
03 indicate we ought to change it.
04 Is that a good
summary?
05 DR. TRUSH:
Yes.
06 MR. JOHNS:
Now, Mr. Kavounas, do you agree with that,
07 we ought to the keep the Monitoring Plan in
place until we
08 have data that would indicate that we ought to
change the
09 plan?
10 MR.
KAVOUNAS: Yeah. You know, these guys say so,
then
11 I believe them.
12 MR. JOHNS: I
am looking where L.A. is on the issue.
13 MR.
KAVOUNAS: Yes.
14 MR. JOHNS:
In terms of who ought to decide change and
15 the adaptive riparian aspects of it, would L.A.
have a
16 problem if it is not just L.A. that makes the
decision, but
17 it is the Board that makes that decision on how
and when
18 that monitoring plan is changed?
19 MR.
BIRMINGHAM: Mr. Caffrey, again, this is a question
20 that I am not sure that the staff can answer.
21 CHAIRMAN
CAFFREY: I apologize because I didn't hear
22 it. I was consulting.
23 MR. JOHNS:
Withdraw the question.
24 MR.
BIRMINGHAM: I, on the other hand, will represent
25 that, as I did in response to Mr. Del Piero's
question this
0323
01 morning, the Board has continuing
jurisdiction. And it is
02 DWP's expectation that, as this process evolves,
despite
03 everyone's best hope, we are going to be back
before the
04 Board, if it is necessary to revise the plan or
to revise
05 what is being done under the plan.
06 I don't know if
that is responsive. I am not trying to
07 interfere with the question.
08 MR. JOHNS:
That is fine. The adaptive management
09 aspects, you could hear in the
crossexamination earlier was
10 giving several of the parties concern about
who's going to
11 adapt what when. And if it is your
position that you don't
12 have a problem with Board being the one that
helps decide
13 the adaptive management aspect, that is where my
questions
14 were heading.
15 MR.
BIRMINGHAM: It is our expectation that it would be
16 the Board to make those decisions with having
provided all
17 the interested parties, those that are here and
those that
18 may not be here, with an opportunity to comment
on what DWP
19 or some of the parties ask the Board to do.
20 BOARD MEMBER DEL
PIERO: Excuse me.
21 CHAIRMAN
CAFFREY: Mr. Del Piero, go ahead.
22 BOARD MEMBER DEL
PIERO: Forgive me, Mr. Birmingham.
23 I understood
everything until the last statement. Our
24 Board has neither the staff nor does the 1631
provide for
25 our staff to be out there monitoring the
performance of the
0324
01 Los Angeles Department of Water and Power in
terms of
02 this. And I hope you aren't suggesting
that somehow we are
03 going to delegate this responsibility to our
staff, since
04 that is not what the decision anticipated in the
first place.
05 MR.
BIRMINGHAM: No, absolutely not. However, the
06 decision does require that the Department, on an
annual
07 basis, submit information to the State Board
staff. And I
08 am confident that every interested party in this
room will
09 obtain that information. And based upon
that information,
10 the State Board on its own initiative or DWP,
based upon
11 what it is being told by its consultants, or
some interested
12 party, thinks that what is happening isn't
consistent with
13 D1631 and the goals and objectives of
restoring,
14 preserving, protecting the stream and fisheries,
then we are
15 going to be back here. It's unfortunate,
but I'm confident
16 we will be back here.
17 BOARD MEMBER DEL
PIERO: I understand that, but that is
18 somewhat different than what the adaptive
management issue
19 that Mr. Johns was phrasing.
20 CHAIRMAN
CAFFREY: I am sorry, you will forgive me. I
21 didn't hear your original question.
22 MR.
BIRMINGHAM: I didn't either, Mr. Johns.
23 BOARD MEMBER DEL
PIERO: It just strikes me, before
24 everybody starts committing this Board to doing
certain
25 things or delegating certain responsibilities, I
am more
0325
01 interested in hearing that the standards for
performance in
02 terms of the Restoration Plan in D1631 has
specifically
03 been addressed before I start agreeing to
delegate anything
04 to anybody.
05 CHAIRMAN
CAFFREY: Everything was just fine until you
06 asking questions, Jerry.
07 MR. JOHNS:
My question related basically to
08 monitoring program, and whether or not the
monitoring
09 program should stay in place until it was
changed. And all
10 I got was, "Yeah."
11 CHAIRMAN
CAFFREY: For the record, I don't have any
12 problem with Mr. Birmingham's characterization
of the ever
13 presence of the Board and all of us who have
followed this
14 issue. I mean, I take it in the most
general context that I
15 believe you are making the statement.
16 MR.
BIRMINGHAM: I believe that the question, the
17 question which Mr. Johns asked which caused me
to rise, was
18 a question really that deals with legal issues
concerning
19 the role of the Board as opposed to whether or
not this
20 particular plan is consistent with D1631.
21 CHAIRMAN
CAFFREY: Thank you, sir.
22 Mr. Johns, please
proceed in your usual style.
23 MR. JOHNS:
Just make sure I understand Dr. Trush's
24 testimony in this other area, as well.
25 I got the idea
that you were saying that you thought
0326
01 perhaps within five to eight years you might
have data on
02 the channel maintenance flows from the
monitoring program to
03 give you some idea on how those flows were doing
in terms of
04 maintaining stream morphology and such.
05 Is that right?
06 DR.
TRUSH: Yes. It is more like a report
card on our
07 best guess as of today.
08 MR. JOHNS:
It is likely that within the time that the
09 lake might fill to, say, the target lake level,
we should
10 have data on the processes going on whether or
not that is
11 being successful.
12 Would that be fair
to say?
13 DR. TRUSH:
My personal number one regard.
14 MR. JOHNS:
Thank you.
15 CHAIRMAN
CAFFREY: We are going to Mr. Canaday or Mr.
16 Frink?
17 MR. FRINK: I
have a fee first and then Mr.
18 Canaday.
19 CHAIRMAN
CAFFREY: Please proceed.
20 MR. FRINK: I
think mine are relatively easier, just a
21 matter of clearing up some loose ends.
22 Dr. Trush and Mr.
Hunter, each of you served on the RTC
23 under the direction of the Superior Court; is
that correct?
24 MR. HUNTER:
Yes.
25 DR. TRUSH:
Yes.
0327
01 MR. FRINK:
Dr. Trush, could you very briefly summarize
02 how the approach toward restoration, which you
currently
03 propose, differences from the stream restoration
proposal
04 that was undertaken or the stream restoration
work that was
05 undertaken at the direct of the court?
06 DR. TRUSH:
When we first came on as the RTC and we saw
07 what was being done at that time, we pretty much
were
08 against any of the instream channel work.
We could see that
09 we received the report that the channel was
not mobile at
10 1200 cfs. I threw that in the waste paper
basket; wish I
11 hadn't because I would like to reference.
It was clearly
12 the channel mobilized way below that. You
could just walk
13 out there and you could see it.
14 So we realized
that we had a mobile channel on our
15 hands, and we had the opportunity to go after
historic flows
16 and go after earlier channel conditions.
17 So, our strategy
went right away to flows. The other
18 thing that we were looking at is what alluvial
surfaces,
19 particularly the middle and the higher terraces,
had been
20 stranded and are most likely not to come
back. We see
21 evidence of riparian vegetation.
22 There's a tricky
area where, if is it not going to come
23 back and there was riparian, should L.A. be
responsible for
24 planting something mesic there. In that it
was it was
25 not going to be, no matter what you do, unless
you put
0328
01 sprinklers out there.
02 So, we did look at
that. But we immediately honed in
03 on the flow prescriptions; spent most of our
time on that.
04 MR. FRINK:
One basic difference would be that the
05 current restoration proposals involve a great
deal less
06 instream work than was previously
undertaken.
07 DR. TRUSH:
Yes. In fact, I think back with Bruce
08 Dodge when we talked about, if these flows
weren't attained,
09 we would go back to building things
instream. We recommend
10 that in our original in the Ridenhour
report. If we
11 keep, like, Lee Vining at no greater than 160
cfs, you are
12 not going to form any channel morphology at 160
cfs in the
13 lower Lee Vining Creek.
14 You can say,
"Well, gee whiz, well maybe we should
15 start building pools then if we are in a static
condition."
16 Trouble is, L.A. it's clear, and Cal Edison
can't control
17 the big floods anyway, even if they wanted
to. If you put
18 in structures, they would go away, anyway.
So even if you
19 provide an inadequate flow, which is, I think,
what has been
20 which is what Lee Vining is under once the
lake fills, I
21 still couldn't even recommend structures because
it wouldn't
22 make any sense; they would go away.
23 MR. FRINK:
Mr. Hunter, would you agree with that
24 assessment?
25 MR. HUNTER:
Yes. Basically, the work has to be done
0329
01 to create the fish habitat. You can either
pay a consult to
02 go out and do an engineering study and build the
habitat or
03 you can let the water do it.
04 MR. FRINK:
Mr. Hunter, do you agree with Dr. Trush
05 that if you did attempt to construct the
habitat, that the
06 conditions in the Mono Basin are such that a
good deal of
07 the instream work is going to wash out
anyway?
08 MR. HUNTER:
The last couple of weeks have certainly
09 shown that.
10 MR. FRINK:
Mr. Kavounas, I have just a point of
11 clarification.
12 Mr. Dodge asked
you if L.A. Exhibit 16 is still Los
13 Angeles's proposed restoration plan, and you
said it is.
14 I assume that
would mean, including the Blue and White
15 Books, DWP Exhibits 22 and 23?
16 MR.
KAVOUNAS: That is correct, yes.
17 MR. FRINK:
Mr. Allen, on Page 5 of DWP Exhibit 29, you
18 state that the flows recommended in the draft
Ridenhour work
19 plan were higher than the typical peak flows
observed in the
20 streams above the DWP facilities. That is
near the bottom
21 of the page.
22 MR. ALLEN:
Yes.
23 MR. FRINK:
Is that true for both Lee Vining and Rush
24 Creeks?
25 MR. ALLEN:
Yes, it is. Because of the fact that what
0330
01 we commonly refer to as flows that we experience
at our
02 facility are termed impaired flows because these
flows
03 include upstream influences of SCE
operations. The
04 Ridenhour work plan flows, however, were based
on unimpaired
05 flows, which would be the flows if there were no
upstream
06 influences. So, in reference to that
second statement, the
07 plans in the work plan were higher than the
unimpaired flows
08 that we experienced.
09 MR. FRINK: I
understand.
10 So, if Los Angeles
ceased its diversions in Mono Basin
11 entirely, removed all its diversion facilities
and dams,
12 would the peak flows recommended in the
Ridenhour Plan be
13 present in Rush and Lee Vining Creeks.
14 MR. ALLEN:
If LADWP were absent the flows below the
15 facilities, would not be those recommended by
the Ridenhour
16 those recommended in the Ridenhour work
plan. Rather,
17 they would be the impaired flows, which, for
clarification,
18 are the influence of those upstream operations
are greater
19 on Rush Creek than they are on Lee Vining
Creek.
20 But in answer to
your question, if DWP were to abandon
21 its facilities, no, the flows that the creeks
would
22 experience would not be the flows recommended in
the
23 Ridenhour work plan.
24 MR.
KAVOUNAS: Point of clarification, if I may.
25 Is that true for
all year types David?
0331
01 MR. ALLEN:
No, not entirely. There may be a situation
02 in the extremely wet year types where the
Southern Cal
03 Edison facilities upstream, their reservoirs
would be full
04 at the time the peak flows occurred, and in that
unique
05 circumstance, then the peak flows downstream of
our
06 facilities would experience unimpaired peak
flows.
07 MR. FRINK:
Dr. Platts, you mentioned the desirability
08 including sediment bypass channel at least on
one of the
09 streams, I believe.
10 What streams was
that on?
11 DR. PLATTS:
That would be WalkerParker.
12 MR. FRINK:
Approximately how many stream restoration
13 projects have you been involved with in your
career, Dr.
14 Platts?
15 DR. PLATTS:
I couldn't even guess.
16 MR. FRINK:
Over a hundred?
17 DR. PLATTS:
Probably a hundred.
18 BOARD MEMBER DEL
PIERO: More than a few and at least a
19 lot.
20 DR. PLATTS:
There you go.
21 MR. FRINK:
Decision 1631, probably for lack of any
22 other alternative, did include some general
criteria
23 indicating that the Board would evaluate
proposed
24 restoration plans on the basis of
reasonableness, economic
25 feasibility, and there were some other criteria
stated.
0332
01 I wonder, based on
your experience of other streams
02 restoration proposals, how would you rate the
overall
03 comprehensiveness and reasonableness of the
Stream
04 Restoration Plan that are presented in this
hearing?
05 DR. PLATTS:
I would rate it rather high, mainly
06 because two reasons. One is that DWP is
taking care of the
07 land management problem, totally. And
number two, they are
08 going to provide the flows that will allow these
streams to
09 rehab.
10 Now, the rest of
it that is the ball game right
11 there. The rest of it, rewatering a few
channels, maybe
12 planting a little vegetation, some of that stuff
is done to
13 make people feel good. Not necessarily
good to make the
14 fish population feel good. With those two
things taken
15 care of, I really believe that the DWP plan,
with the
16 adequate monitoring to go with it so that they
get into the
17 adaptive management, I think that it is a given
that those
18 streams are going to recover.
19 MR. FRINK:
Would you include, though, that if it is
20 feasible, a sediment bypass channel should be
provided at
21 the Parker and Walker Creek diversion
facilities?
22 DR. PLATTS:
Yes. I think Parker and Walker should
23 have some type of a sediment bypass
facility. I do not see
24 ParkerWalker hurting in any way at this time
because it is
25 not getting sediment. I see no problem
below, but I think
0333
01 it is just it would just be good in the
future; make sure
02 that the sediment bypass facilities do
work. Just so we
03 don't get in any trouble.
04 Right now there is
no problem.
05 MR. FRINK:
Thank you. That is all the questions I
06 have.
07 CHAIRMAN
CAFFREY: Mr. Canaday.
08 MR. CANADAY:
Thank you. First, just to clarify
09 something for me, this is Exhibit DWP67, Dr.
Kauffman's.
10 It is a bar graph, and at the bottom, it talks
about
11 identification number. And I am trying to
understand what
12 that relates to.
13 DR.
KAUFFMAN: Various plant community dominance of
14 which I didn't include that in my testimony
this morning.
15 Since it has been admitted to evidence, I would
need to also
16 admit in evidence a legend so you could
interpret the bar
17 graph of what the numbers mean.
18 BOARD MEMBER DEL
PIERO: That was going to be my
19 question, what is this thing?
20 DR.
KAUFFMAN: Each one. For example, community
one is
21 black cottonwood. Community two is coyote
willows, et
22 cetera, et cetera, et cetera.
23 MR. CANADAY:
I will assume that under recross or
24 redirect that somehow that will get into
evidence?
25 DR.
KAUFFMAN: It is in here.
0334
01 CHAIRMAN
CAFFREY: It is already in the record; is that
02 correct?
03 DR.
KAUFFMAN: I would have to enter in some
04 corrections, in that 24 there is a few
others that aren't
05 in here, 22 and 23 and 24.
06 CHAIRMAN
CAFFREY: Mr. Birmingham, you will take care
07 of that on redirect?
08 Thank you,
sir.
09 Mr. Canaday.
10 MR. CANADAY:
Thank you.
11 Just so that I am
clear in my own mind, there has been
12 a lot of testimony about the flows, the
recommended flows
13 for this restoration plan. And so that I
am clear in my
14 mind of what is actually being proposed is, I am
assuming,
15 Table 1 and Table 2, Page X of the Mono Basin
Grant Lake
16 Operations and Management Plans.
17 And, I guess, to
you, Mr. Kavounas, is that, first of
18 all, the flow proposal that is being made to the
Board?
19 MR.
KAVOUNAS: Give me a second to find my plan.
20 MR. CANADAY:
I will ask also the scientists if that is
21 their understanding of the flow regime that they
are making
22 their recommendations on, as well.
23 DR. BESCHTA:
Where are we at?
24 MR. CANADAY:
It's Page X, the Grant Lake Operations
25 Plan, Table 1 and Table 2. It is in the
main document.
0335
01 MR.
KAVOUNAS: Yes. The flows that are indicated
in
02 Tables 1 and 2 on Page X of the Grant Lake
Operations Plan
03 are what DWP is proposing.
04 I should point out
that Table 2, Proposed Maintenance
05 Channel Flows, those are flows that we will try
for with
06 intent of maximizing where possible, exceeding
where
07 possible.
08 MR. CANADAY:
Let me ask you further questions about
09 this. Table 1 represents the LADWP
proposed base flow
10 release from Mono Basin; is that correct?
11 MR.
KAVOUNAS: That is correct.
12 MR. CANADAY:
And Table 2 is LADWP proposed channel
13 maintenance flow for the Mono Basin creeks; is
that correct?
14 MR.
KAVOUNAS: That is correct.
15 MR. CANADAY:
I believe I heard earlier today that
16 these are recognized as minimums and that they
may be
17 exceeded at times, based on the range and these
water year
18 types. I think Mr. Allen
19 Is that correct,
Mr. Allen?
20 MR. ALLEN:
Yes, that is correct.
21 MR. CANADAY:
I would like to hand this to the stream
22 scientists. Dr. Beschta is looking at it.
23 Are these the
flows that you are making your
24 recommendations on for the plan, Dr.
Beschta?
25 DR. BESCHTA:
These are, indeed, the flows that I
0336
01 looked at for my comparisons when I came to the
conclusion
02 that they are within the realm. They
represent a close
03 approximation, let's say, of the unimpaired
flows. I was
04 basing them on these.
05 I also looked at
the Ridenhour flows, and agree with
06 David that, by in large, most the time they were
above the
07 unimpaired flow levels.
08 MR. CANADAY:
The purpose of my question to you all is
09 to make sure that when you all have been talking
about
10 flows, that you think are going to be a part of
this plan
11 that you intend to monitor, I want to sure what
flows you're
12 talking
about.
13 So, my question
now is to Dr. Platts, Mr. Hunter, and
14 Dr. Trush: Is, in fact, Table 1 and Table
2, as it is
15 represented in that exhibit, are those the flows
under which
16 you understand that you are going to be
monitoring, and
17 which you are agreeing to, that this plan meets
the
18 restoration requirement?
19 MR. HUNTER:
Yes.
20 DR. PLATTS:
Yes.
21 DR. TRUSH:
Yes.
22 MR. CANADAY:
Thank you.
23 I would like to
refer to the, I guess we call it the,
24 ad hoc letter from the ad hoc committee, the
February 13,
25 1996 letter to Mr. Kavounas from Dr. Ridenhour,
which
0337
01 represents assumed findings and recommendations
from the ad
02 hoc flow committee.
03 I would like to
refer you to Page 3 of that letter,
04 the second paragraph under Item Number 3.
It says:
05
This alternative...
(Reading.)
06 And it is
referring to making releases from the Mono
07 ditch in concert with approximately 150 cfs from
the Lee
08 Vining conduit or Sand trap Number 5 and
possibly spills
09 from Grant Lake.
10 But it says:
11
This alternative could provide acceptable
12
stream habitat maintenance flows for Rush
13
Creek below the Narrows, but would not
14
provide acceptable restoration and
15
maintenance flows above the Narrows.
16
(Reading.)
17 My question to
you, Dr. Trush: Do you now disagree
18 with that?
19 DR. TRUSH: I
think I disagreed with it when the letter
20 was there. It is clear I don't
remember.
21 MR. HUNTER:
If you've ever read the number of memos
22 Rich passes by, a couple slip through.
23 MR.
KAVOUNAS: I would be glad to take you to our file
24 room.
25 DR. TRUSH:
What we based our question on above is,
0338
01 above 395 after we had the high flow and we saw
the various
02 things that had happened downstream, below the
Narrows, we
03 went up to a couple of excavated pools that were
clearly
04 hydrologically going to fill in if bedload
moved. There is
05 no way those could survive if the bed
moved. We went there,
06 and they are still deep, which surprised us.
07 And that is our
only evidence, really, of a question
08 mark as to why didn't those big pools fill in,
because there
09 were gravel deposits. Maybe it was
transporting it
10 through, but I just don't see it. It was
just a big hole
11 with no slope. Should have filled, but it
didn't. That was
12 what we based our concern over.
13 But I can't say
that 500 doesn't do it. I really would
14 not agree with that. The monitoring, I
think, will slow
15 whether it does or not. There is that
nagging question,
16 why didn't those holes fill?
17 MR. CANADAY:
Your present testimony is that the flows
18 that are identified in Table 2, which is the
proposed
19 channel maintenance flow by LADWP, that those
flows above
20 the Narrows should be able to do the types of
work and
21 generate the fluvial processes that you intend
to monitor
22 and you believe the plan will accomplish?
Is that correct?
23 DR. TRUSH:
As your first guess, yes.
24 MR. CANADAY:
The monitoring, then, will fine tune
25 that, that opinion?
0339
01 DR. TRUSH:
That is our intention.
02 MR. CANADAY:
Mr. Hunter, you agree with that as well?
03 MR. HUNTER:
Absolutely.
04 MR. CANADAY:
Dr. Platts, you agree with that?
05 DR. PLATTS:
Absolutely.
06 MR. CANADAY:
Just to refer to a few sound bites that I
07 heard this morning about some perspectives of
how long we
08 might have certain expectations for
recovery.
09 I believe it was
Dr. Kauffman who said, "We have a long
10 way to go for recovery." You didn't
put a time limit on it,
11 but a long time.
12 Isn't that
correct, you made a statement like that?
13 DR.
KAUFFMAN: Something like that.
14 MR. CANADAY:
By a long time, you are talking decades,
15 minimum?
16 DR.
KAUFFMAN: In terms of achieving the potential
17 vegetation structure, I would measure that more
in decades.
18 How long would it take a cottonwood to become
mature would
19 be decades. How long will it take the
deltaic, the area of
20 incision, Reach 5, would be measured in
geological time.
21 MR. CANADAY:
I was talking more about some of the
22 processes you were hoping to achieve, the flow
pattern. And
23 so, we are talking in areas of decades at least
for the
24 riparian recovery that you testified to?
25 DR.
KAUFFMAN: Yes.
0340
01 MR. CANADAY:
I think, Dr. Platts, you testified that
02 one of the ideas of the monitoring was to
provide
03 information to kind of tweak the system.
In other words,
04 provide what your best guess is for this
recommendation,
05 recollection flow, base flows and channel
maintenance flows,
06 and then monitor that, and look at the indices
that you are
07 proposing in your plan to evaluate, and then
make further
08 recommendations somewhere down the road.
09 DR. PLATTS:
Yes. That is the only way it will work.
10 MR. CANADAY:
I believe you said you gave numbers,
11 I am not going to hold them to you, but in
reference you
12 said 20 to 40 years, possibly, for some of these
things that
13 you are looking at for restoration.
14 DR. PLATTS:
Yes. It depends where you are on the
15 system. Different reaches, different
habitat types are
16 going to respond at different times. There
are some areas
17 like Rush Creek, say, from Grant to 395 that are
probably
18 better than pre1941 conditions. When you
get below there,
19 it's going to take quite a while, a long time,
for them to
20 get pre1941 conditions.
21 On Lee Vining
Creek, if you are below the dam, down to
22 395, we probably got conditions just as good as
they were
23 pre1941. From there on down, that is
going to be a slow
24 process. All you can do is set the stage
in motion, knowing
25 that you are going to be successful. And
like we say, you
0341
01 build it, they will come. It will happen.
02 MR. CANADAY:
Now that you mention, "you build it and
03 they will come," the "they" you
are referring to is?
04 DR. PLATTS:
The fish population and the wildlife.
05 MR. CANADAY:
That leads me to the fisheries
06 monitoring. The face plate or snorkeling
survey that is
07 proposed in this particular plan, based on the
technique
08 that you are proposing, will you be able to, or
any
09 scientist can answer that, will you be able to
determine
10 growth rates from the data which you intend to
collect?
11 MR. HUNTER:
Because there will be validation with the
12 electrofishing and the intent is to weigh and
measure the
13 fish that are collected when they do the
electrofishing
14 validation. Should be able to do
that.
15 MR. CANADAY:
Will not the electrofishing and the
16 validation, won't that be a onetime
study? Or how I can
17 get no idea out of the plan, how many times you
intend to do
18 that? So I am assuming it was a onetime
validation study,
19 and from that onetime sample, you intend to
look at age?
20 MR.
HUNTER: I guess I didn't anticipate it being one
21 time.
22 MR. CANADAY:
How often would you
23 MR. HUNTER:
I would expect them to do it each time.
24 MR. CANADAY:
Each time?
25 MR. HUNTER:
Yes.
0342
01 MR. CANADAY:
Moving along to sediment bypass. Again,
02 I will ask that any of the fishery scientists to
respond.
03 What time of the
year do brown trout spawn in Mono
04 Basin streams?
05 DR. PLATTS:
I haven't seen any spawn in the Basin,
06 but I would imagine November, December.
Again, November,
07 December would cover most of it.
08 MR. CANADAY:
Are you aware that the sediment bypass
09 plans call for moving fines and sediment through
the system
10 from the months starting in October through the
winter
11 months?
12 DR. PLATTS:
Yes, I am.
13 MR. CANADAY:
Is that one of the things you don't like
14 about the plan?
15 DR. PLATTS:
That is one of the major things. That is
16 not the major thing. It is one of the
things that I don't
17 like about the plan.
18 MR. CANADAY:
By taking that activity wouldn't it, in
19 fact, have an impact on if there were brown
trout spawning
20 in those streams below those release points?
21 DR. PLATTS:
It could, immediately below the dam, yes.
22 BOARD MEMBER DEL
PIERO: It might not be interested in
23 spawning if they were getting a face full of
mud.
24 MR. CANADAY:
Already have the eggs in the gravel.
25 DR. PLATTS:
They will spawn, regardless.
0343
01 MR. CANADAY:
Dr. Trush, do you believe that your
02 monitoring plan for the various microhabitat
conditions or
03 these channel conditions, do you think it is
going to be
04 sensitive enough to be able to determine the
differences of
05 these fluvial processes at 500 and 600 cfs,
since there
06 seems to be an argument about how high it should
be?
07 DR. TRUSH:
Based on the work I have done in other
08 streams, I have been able to narrow that window
of mobility
09 to 50 cfs for higher discharge streams than
this. So I
10 think I could. Not every attribute.
There is going to be
11 overlaps, 5 to 600 will be difficult. But
I think on
12 incipient conditions, yeah.
13 MR. CANADAY:
This is for Mr. Kavounas or Mr. Allen.
14 In testimony we will hear later on, I am going
to ask you
15 first have you read it, would be proposed
testimony by Mr.
16 Harrison, I believe, of National Audubon/Mono
Lake
17 Committee, referring to an Iowa vane as a way to
construct
18 and inpool device for moving sediment through
the system,
19 particularly for Lee Vining.
20 Are you familiar
with those systems at all, the Iowa
21 vane?
22 MR. ALLEN: I
myself am not, no. I would have to do
23 some more research on that.
24 MR. CANADAY:
Mr. Kavounas.
25 MR.
KAVOUNAS: Mr. Canaday, I read Mr. Harrison's
0344
01 testimony, and his concept of Iowa vanes
intrigued me. I am
02 not familiar with an Iowa vane system. I
asked people
03 throughout the Department that might have had
some
04 experience. Nobody seemed to know. I
placed a phone call
05 on Sunday night to Mr. Harrison to ask him
specifically to
06 fax me any information he might have had, and I
did not get
07 a response to the phone call.
08 MR. CANADAY:
That is information we need to evaluate?
09 MR.
KAVOUNAS: I look forward to Mr. Harrison's
10 testimony here; that concept intrigued me.
11 MR. CANADAY:
Grazing, it is my understanding that the
12 LADWP plan proposes a tenyear
moratorium.
13 Is that correct,
Mr. Kavounas?
14 MR.
KAVOUNAS: To my recollection, the plan proposes a
15 tenyear moratorium from the time the Board
approves the
16 plan.
17 MR. CANADAY:
Dr. Kauffman, isn't it your
18 recommendation in your testimony that the
grazing plan be
19 indefinite?
20 DR.
KAUFFMAN: Yes, it is.
21 MR. CANADAY:
By that term, what kind of time frame are
22 you suggesting?
23 DR.
KAUFFMAN: Indefinitely.
24 MR. CANADAY:
Dr. Beschta, I believe you made a similar
25 recommendation?
0345
01 DR. BESCHTA:
Yeah, I believe that the longterm
02 removal of grazing would be particularly
important for this
03 system, on public lands certainly.
04 MR. CANADAY:
Thank you.
05 Mr. Tillemans, one
of the only of two several active,
06 restoration activities that is proposed in the
LADWP plan,
07 and one of those is a limited vegetation
planting program.
08 Is that correct?
09 MR.
TILLEMANS: That is correct.
10 MR. CANADAY:
It is primarily focused on conifer
11 species; is that correct?
12 MR.
TILLEMANS: In the interfluve sites.
13 MR. CANADAY:
Are you proposing any riparian planting,
14 as well?
15 MR.
TILLEMANS: We proposed the sites we proposed
16 for riparian plants would be in the vicinity of
Reach 3B by
17 old Highway 395 and possibly below the County
Road on Lee
18 Vining Creek and near 3C, 3D.
19 MR. CANADAY:
Those specific sites will be determined
20 in the field; is that correct?
21 MR.
TILLEMANS: Yes. Although I do agree with
Boone's
22 recommendation that there is really no necessary
23 revegetation.
24 MR. CANADAY:
Understood.
25 MR.
TILLEMANS: That was based on input from the
0346
01 parties.
02 MR. CANADAY:
Part of either the actual labor and/or
03 funding is proposed in the plan to come from
volunteers; is
04 that correct?
05 MR.
TILLEMANS: I think that is correct.
06 MR. CANADAY:
If that volunteer activity is not
07 available, do you still intend to carry forward
with the
08 plan?
09 MR.
KAVOUNAS: In the absence of volunteer labor, the
10 Department will still conduct the work.
11 MR. CANADAY:
Thank you.
12 BOARD MEMBER
FORSTER: I didn't hear the answer.
13 MR.
KAVOUNAS: My answer was, the Department would
14 carry on the work even in the absence of
volunteer labor.
15 CHAIRMAN
CAFFREY: Thank you, sir.
16 MR. CANADAY:
On proposal for large woody debris, which
17 is the other main channel restoration activity
that is in
18 the LADWP plan, are there stream sections that,
in fact, are
19 lands under the stewardship of U.S.
Foresters?
20 MR.
KAVOUNAS: I believe so.
21 MR.
TILLEMANS: Yes, that is true.
22 MR. CANADAY:
If the U.S. Forest Service recommendation
23 on their lands was to cable large woody debris,
what would
24 you recommend?
25 MR.
TILLEMANS: Could you finish?
0347
01 MR. CANADAY:
If it is a permit condition of the U. S.
02 Forest Service on their lands to
03 MR.
TILLEMANS: To anchor
04 MR. CANADAY:
The large woody debris.
05 DR. PLATTS:
Use real small cables.
06 MR.
KAVOUNAS: As you can tell from the panel, the
07 advice I have received is, that is a pointless
exercise to
08 get into. If it was a condition of the
permit, we'd
09 probably call you for advice.
10 MR. CANADAY:
In reading your long, largely woody
11 debris program, I would typify it as something
you intended
12 to do early on in the restoration process, and
it would be
13 over a short period of years, but with no
followup in the
14 future.
15 Is that
correct?
16 MR.
TILLEMANS: That is correct.
17 MR. CANADAY:
What would be the if you had initiated
18 a large woody debris program in November, where
would that
19 debris be today in the streams and channel
systems?
20 MR.
KAVOUNAS: In Lee Vining, it would probably be in
21 the lake.
22 MR. CANADAY:
It would be driftwood?
23 MR.
KAVOUNAS: Yes. In Rush Creek, it would
probably
24 still be in place.
25 I am sorry, can I
retract my answer? There are people
0348
01 here who are better qualified, please.
02 DR. BESCHTA:
If the dimension of the piece is longer
03 than the width of the channel, they generally
don't go very
04 far. In fact, most pieces don't go very
far in most
05 channels, the more complicated the channels
become. So
06 through time, the likelihood of wood moving
through that
07 system very far gets less and less and
less.
08 It is one of these
problematic things. The hypo is now
09 yes, a fair amount of wood is now moving through
the system.
10 In a few more years, less will be able to move
very far at
11 all. Through time, even less yet.
So, yes, wood does move,
12 but it will be on a decreasing curve.
13 MR. CANADAY:
That leads to the importance of using
14 the pieces that you do put in have to be that
fairly large;
15 is that correct?
16 DR. BESCHTA:
That depends whether you think these
17 systems develop having large woody debris as a
major and
18 significant component. My opinion would be
that the willow
19 communities and the cottonwoods, as they exist,
and the
20 roots and the stems that they have are much more
important
21 than any large wood anybody will place in that
system.
22 So, in my view, if
you're looking for roughness, and if
23 you are looking for scouring pools, and if you
are looking
24 for undercut banks, you can put wood in there,
but it is not
25 a necessary requirement to develop that
system. You can do
0349
01 it, but you don't need it.
02 MR. CANADAY:
Dr. Trush, is there value to implementing
03 a large woody debris program in these
streams?
04 DR. TRUSH:
Well, originally how we came up with this,
05 we were going to dinner in Mammoth, and we saw
them
06 cleaning, grading the new route parallel to
395. They had
07 all this beautiful woody debris stacked up ready
to burn it.
08 "Well, why don't we put it in the
stream?" And didn't know
09 this would generate. And I think if I had
to do it all over
10 again, I would say to the Forest Service or
someone else,
11 "You guys take it and put it in a little
stream somewhere
12 else, and we won't worry about it."
13 I still think it
is helpful. I would put it in lower
14 Lee Vining Creek. I think the larger
stuff, larger pieces,
15 would strand, and that it would act as a
benefit, not a
16 major benefit, to the channel, and that the
program should
17 be purely
opportunistic.
18 It is unfortunate
that we didn't get there in time
19 because the standard stuff, the Caltrans
employees buck it
20 up, all the way up to the root ball. So,
you have bowling
21 balls. If a little foresight could be out
there, we'd keep
22 a ten foot stem on that root ball. I would
be very much in
23 favor of putting a few more of those in when the
opportunity
24 arose. But that would be the depth of a
program; however I
25 would like that.
0350
01 MR. CANADAY:
Questions about the Mono Gate Return
02 Ditch. My recollection from the reading of
your plan is
03 that it is the position of the Los Angeles
Department of
04 Water and Power that return ditch is not to be
used as a
05 surrogate for Reach 1.
06 Is that correct,
Mr. Kavounas?
07 MR.
KAVOUNAS: As a surrogate for
08 MR. CANADAY:
For fisheries habitat.
09 MR.
KAVOUNAS: I can't answer that question. It
is not
10 my field of expertise. I am not so sure
I am not sure
11 what would be
12 MR. CANADAY:
If I represent there was language such as
13 that in the plan, would you agree with that?
14 MR.
KAVOUNAS: Yes. But for clarification, maybe I
can
15 turn it over to Brian.
16 MR.
TILLEMANS: I am not an expert on flow. If
you can
17 we will call it a surrogate. But, as
you know, it does
18 provide fish habitat. We have many canals
on our property
19 that are highly prized by DF&G in terms of
fishery habitat,
20 and I will show you in temporarily cleaning this
ditch, the
21 elodea, the aquatic vegetation that is
persistent on the
22 bottom, quickly comes back. In fact, that
is why we have
23 maintenance programs on our canals in the Owens
24 Valley. There are many fisheries'
biologists within the
25 area that say that is why the brown trout really
like those
0351
01 canals: because it is slow moving water, and
they have that
02 cover of elodea to hide it. So, it is a
temporary setback
03 on cleaning, but there will definitely be fish
habitat in
04 the ditch.
05 MR. CANADAY:
So, the design of the reclamation or
06 restoration of the Mono B Ditch could
incorporate conditions
07 or design that would create fisheries' habitat,
in this case
08 possibly for large adult fish.
09 Is that
correct? That is what I am hearing from your
10 response.
11 MR.
TILLEMANS: If a canal if you are referring to
a
12 canal design, like we have every place else
where we have
13 fisheries in our canals, which is just,
basically, constant
14 grading and flat.
15 MR. CANADAY:
It is your experience that your canals do
16 support fish, catchable size?
17 MR.
TILLEMANS: Most definitely. And, in fact, the
18 Bishop Creek Canal, I can recall ten years ago
or so, we had
19 discussions that Fish and Game wanted to include
it in their
20 wild trout streams.
21 MR. CANADAY:
Mr. Allen, question about the Upper Owens
22 River flows. I refer you to the D1631,
which is on Pages
23 203 and 204, Item Number 7.
24 To paraphrase Item
Number 7, what it instructs the City
25 of Los Angeles is, that its discharge from East
Portal shall
0352
01 not exceed the combined natural flow of the
Owens River at
02 East Portal and whatever is released from East
Portal up to
03 250, no greater than 250 cfs.
04 Is that correct?
05 MR. ALLEN:
Yes, that is correct.
06 MR. CANADAY:
It also instructs the licensee that any
07 releases made to Upper Owens River will be made
at
08 relatively stable rates, constant with
operations,
09 limitations, and water availability.
10 Is that, in fact,
what will be incorporated into the
11 Grant Lake Operations Plan for LADWP exports,
that they will
12 be they will not be pulsed over the year?
13 MR. ALLEN:
Yes, that is the intent of the plan.
14 Comparing flows with the Upper Owens River in
comparison to
15 the, say, the flows of the Mono Basin streams,
what you find
16 is that there is less variation between, say,
the summer
17 peak flows and the winter base flows. So
we commonly refer
18 to the Owens River as kind of a springfed
system. Although
19 some parties may not agree with that
terminology, the main
20 point here is that there is a small variation
between the
21 summer peak flows and well, there isn't as
much variation
22 between the peak flows and the wintertime base
flows as we
23 see on the Mono Basin creeks.
24 In our plan,
during the period while Mono Basin is
25 increasing from 6380 to 6392, the plan calls for
a constant
0353
01 diversion of 22 cfs, with the exception of the
upper bound
02 of the normal year types, in which we would
gradually
03 decrease diversions in order to accommodate the
channel
04 maintenance flow requirements of Rush
Creek. So, I believe
05 that the exports presented in our plan are
consistent with
06 Item 7 of D1631.
07 MR. CANADAY:
The capacity that has been identified is
08 for the upgrading and restoration of the Mono
Gate Return
09 Ditch is 350 to 380 cfs.
10 Is that
correct?
11 MR.
KAVOUNAS: Yes.
12 MR. CANADAY:
That amount is limited by the diversion
13 facility at Grant Lake. What creates the
limit of 350 to
14 380 cfs?
15 MR. ALLEN:
To my knowledge, that is the outlet total
16 capacity from Grant Lake.
17 BOARD MEMBER DEL
PIERO: Total capacity?
18 MR. ALLEN:
Yes.
19 MR. CANADAY:
In your plan, you propose to monitor all
20 the diversion points and release points along
the LADWP
21 project. How much of those diversion
structures are
22 telemetered, that recording date is telemetered?
23 MR. ALLEN:
On WalkerParker Creeks and Lee Vining
24 Creek, those three facilities are
telemetered. In addition
25 to that, we also telemeter Grant Lake outflow
and Grant Lake
0354
01 Reservoir elevation.
02 MR. CANADAY:
By "outflow," it's the diversion tunnel,
03 then, that is telemetered?
04 MR. ALLEN:
Yes. It's actually it's measured at the
05 outlet tower of Grant Lake Reservoir, so it's
specifically
06 outflow from Grant Lake Reservoir.
07 MR. CANADAY:
Is there a way to possibly telemeter the
08 as you telemeter the Mono Gate Ditch?
09 MR. ALLEN:
It is feasible to do that, yes.
10 MR. CANADAY:
Is it possible to telemeter the sand trap
11 where you propose to make releases of 150 cfs to
meet your
12 bypass flows or channel maintenance flows?
13 MR. ALLEN:
It is possible. However, I don't you
14 know, depending on the actual channel
characteristics, it
15 may be difficult to actually predict what the
flows are
16 directly at the release facility. There
may be a more
17 appropriate measurement facility that can be
used for
18 determining those flows. The release is
specifically from
19 the conduit.
20 MR. CANADAY:
So. There is an ability to monitor and
21 measure that release being made and then, by
having
22 knowledge of what release is being made from
Mono Gate, you
23 would know when the flows are being introduced
into the
24 lower part of Reach 1?
25 MR. DAVID:
Yes, that is correct. Well, actually, the
0355
01 methodology that we were proposing to use was to
at each
02 diversion facility, we measure the flow, both
upstream and
03 downstream, of the diversion facility. And
so, with the sum
04 of the total diversions, in addition to the
releases in the
05 Mono Ditch, we can calculate what the flows in
Lower Rush
06 Creek are. And this is a similar method
which we use to
07 determine flows in Lower Rush Creek, say for
example, when
08 Grant Lake Reservoir is spilling. We use
the spill in
09 combination without flow from the return ditch.
10 MR. CANADAY:
I am looking for ways that we can
11 possibly monitor or telemeter these diversions
and release
12 points for realtime data. So, that if
parties were
13 interested in tracking the compliance with these
conditions,
14 that they could be done, rather than relying on
a month
15 later calculation from data that has been
collected.
16 Is that possible?
17 MR. ALLEN:
Yes, it is possible. However, may I add,
18 specifically with the channels, going back to,
say, the Mono
19 Return Ditch, one of the problems is that it is
a ditch, and
20 the method for calculating flows there is
actually a
21 couple of methods that you can use.
22 One method would
be to measure the stage of the flow
23 and estimate the flows using known hydrologic
equations.
24 The method that we use is that we take flows in
the return
25 ditch as the difference between Grant Lake
outflow and the
0356
01 flows that we measure at the East Portal, which
go to Upper
02 Owens River. And it is kind of a back
calculation because
03 we have to subtract out the base flows that
occur from the
04 Mono Tunnel.
05 MR. CANADAY:
But it is feasible to establish a
06 measurement in the monitoring program that one
could get
07 realtime releases from these particular
points; isn't it?
08 MR. ALLEN: I
would question the accuracy of a
09 measuring device on the Mono Return Ditch.
And then, in
10 addition to that, I would also question
well, I can't say
11 as to the adequacy of a measuring device on the
return
12 channel without knowing what it is. Not
the return channel,
13 excuse me, but the conduit channel which would
go from the
14 conduit to the confluence of Rush Creek.
15 MR. CANADAY:
In the design of the Mono Gate Ditch,
16 which is being proposed by the City of Los
Angeles, there is
17 an opportunity to look at a way of designing a
section of
18 stream in which a stream flow could be measured
and
19 telemetered because you can create a channel
there or a
20 geometric design with which you can do that; is
that correct?
21 MR. ALLEN:
Yes, that is correct.
22 MR. CANADAY:
Mr. Kavounas, I heard mentioned earlier
23 that the Restoration Plan or the Monitoring Plan
would
24 possibly be let out to bid.
25 Are you proposing
any oversight by scientists that
0357
01 prepared this plan so that we have some sort of
assurance
02 that, in fact, their intent is carried forward?
03 MR.
KAVOUNAS: Not specifically in the plan. I
expect
04 that what would happen procedurally, is that the
Department
05 spec would have to come out and in doing so, I
would
06 consider seeking advice from the scientists that
prepared
07 it.
08 MR. CANADAY:
I am more interested in their review of
09 the reports prepared by the contractor who
physically did
10 the work and collected the data.
11 MR.
KAVOUNAS: This is a little difficult for me to
12 answer. I can't really commit to using the
scientists
13 because that is committing my Board of
Commissioners to
14 hiring a particular consultant. I can
certainly tell you
15 that they have highly relevant expertise.
And if they were
16 to submit a statement of qualifications, they
would be
17 highly qualified.
18 MR. CANADAY:
Finally, Dr. Allen Mr. Allen, based on
19 the potential water year that we may have come
this spring
20 runoff, given the existing condition of the Mono
Gate Ditch,
21 is it likely that L.A. will be able to make a
wet year or
22 extreme wet year release for channel maintenance
flow this
23 year?
24 MR. ALLEN:
At this point, I really can't say exactly
25 what kind of flows we will expect. One of
the things is, we
0358
01 need to rehabilitate the return ditch. At
this point, I can
02 say that I believe the Grant Lake Reservoir has
started to
03 spill already, due to the flows that we had
earlier this
04 month, and that the operations for this year
will likely
05 strictly flow through conditions on the
reservoir.
06 Essentially, we will plan to just flow through
whatever
07 comes in above Grant Lake, believe pass through.
08 MR. CANADAY:
The estimated time it will take for
09 permitting, planning, and doing the physical
work for the
10 Mono Gate Return Ditch is in your exhibit;
approximately two
11 years. Is that still
12 MR.
KAVOUNAS: I believe so.
13 MR. ALLEN:
That is from the data approval by this
14 agency. Is that correct?
15 MR.
KAVOUNAS: That may be optimistic. I don't
recall
16 if the CEQA process was included in that.
17 MR. CANADAY:
Thank you. That is all I have.
18 CHAIRMAN
CAFFREY: Thanks to the staff for those
19 questions. That now let me ask
Esther.
20
(Discussion held off record.)
21 CHAIRMAN
CAFFREY: We need to take a break before we
22 start redirect.
23 Mr. Birmingham, I
thought you were rising to comment.
24 MR. DODGE:
Mr. Chairman, I thought we agreed that we
25 were going to stop at 8:00.
0359
01 CHAIRMAN
CAFFREY: Well, I don't know that we agreed.
02 You and I had a discussion that we were going to
try and
03 stop at that point. But I think, in the
interest in getting
04 this panel out of here and everybody is willing
to go a
05 little further
06 Let's ask Mr.
Birmingham how much redirect he has. We
07 don't put any pressure on you, Mr.
Birmingham. Five
08 minutes? Ten minutes?
09 MR.
BIRMINGHAM: A minimum of a half an hour.
10 CHAIRMAN
CAFFREY: I can do that. I can certainly stay
11 that long. I know we have two. Mr.
Del Piero and I can
12 stay that long. We have a couple Board
Members that have to
13 leave in about half hour.
14 MR. DODGE:
Mr. Chairman, I am getting pretty tired,
15 and if you want to change to 8:30, I will hang
on. But I am
16 getting pretty tired.
17 CHAIRMAN
CAFFREY: Well, that's unfortunate because
18 there are a lot of folks here and we have
limited time to do
19 this. If perhaps you would want to go
first, if it was
20 agreeable to the other parties, we would put you
first for
21 recross. That would be a
possibility.
22 Mr. Birmingham.
23 MR.
BIRMINGHAM: May I inquire, Mr. Caffrey, of the
24 panel?
25 CHAIRMAN
CAFFREY: Please.
0360
01 MR.
BIRMINGHAM: The panel has been on since 9:00 or
02 10:00 this morning?
03 CHAIRMAN
CAFFREY: They are a pretty tough bunch. No
04 question about it.
05 BOARD MEMBER DEL
PIERO: We are going to lose them
06 tomorrow, right?
07 MR.
BIRMINGHAM: No.
08 CHAIRMAN
CAFFREY: I thought that was your point.
09 MR.
BIRMINGHAM: There is one member of the panel who
10 has a class tomorrow. Dr. Kauffman has to
leave to teach a
11 class at Oregon State tomorrow evening. He
can be back on
12 Thursday. The remainder of the panel can
be here in the
13 morning. And, actually, I only have a few
questions of Dr.
14 Kauffman on redirect. And maybe what I
would do, just to
15 save time, is to say I would bring him back on
our rebuttal
16 case and to respond to those questions.
17 CHAIRMAN
CAFFREY: So, you are suggesting, perhaps,
18 that we just adjourn now and then, if everybody
is in
19 agreement, you would bring Dr. Kauffman back on
Thursday.
20 Is that what I
hear? I am sure that thrills Dr.
21 Kauffman.
22 BOARD MEMBER DEL
PIERO: This is a deal here, pal, so
23 you better make a commitment one way or the
other.
24 MR.
BIRMINGHAM: Dr. Kauffman expressed to me his
25 availability to come back Thursday. I will
commit to bring
0361
01 him back. A lot of people in the audience
are nodding their
02 heads up and down, saying, yeah. But it is
the Board that
03 controls this decision.
04 CHAIRMAN
CAFFREY: I think we are a fairly resilient
05 Board, and we can go many, many hours. We
do this a lot.
06 BOARD MEMBER DEL
PIERO: One, two, three in the morning.
07 CHAIRMAN
CAFFREY: Mr. Del Piero and I have this thing,
08 we can go till 3:00 a.m., just to see who gets
tired first.
09 But, having said that
10 BOARD MEMBER DEL
PIERO: That pepped you all up, didn't
11 it.
12 CHAIRMAN
CAFFREY: I want you to understand, at least
13 the Chair, and I am sure the other Board
Members, we want
14 very much to finish this in the three days
allotted. And we
15 are going to make another assessment tomorrow
afternoon.
16 If that means
tomorrow afternoon at about 5:00 we take
17 a hour and a half break for dinner and then we
go to
18 midnight, because that is what we are going to
have to do to
19 finish it on the third day, that is what we are
going to do.
20 I would just say
to all of you, to be efficient and
21 crisp in your crossexamination because I will
observe that
22 some are more crisp than others and still get it
down. So,
23 maybe that is a question of style, but it is
something to
24 think about as we proceed through this.
25 So, Dr. Kauffman
0362
01 DR.
KAUFFMAN: I would very much prefer to complete my
02 testimony and my panel responsibilities this
evening, if at
03 all possible. It certainly would
04 MR.
BIRMINGHAM: It is not possible, Dr. Kauffman.
05 CHAIRMAN
CAFFREY: I think it is becoming impossible.
06 People are tired, and it's pretty tough to know
how long the
07 crossexamination is going to take. We
could end up here
08 till midnight, if we go through with it.
09 I think you are
all going to be pretty exhausted. You
10 might regret having asked for that a few hours
from now. I
11 know it is difficult for you to come back.
We appreciate
12 your attempt and your deference.
13 With that, we are
at the point now where we would go to
14 redirect. I hear everybody saying they
would like to call
15 it a night.
16 We would be back
here I am not coming back at 8:30,
17 as Mr. Dodge suggested. We will back at
18 Thank you, Mr.
Dodge, for offering it.
19 We will back at
9:00, and we will hit it as hard as we
20 can, and see where that takes us.
21 Mr. RoosCollins,
you were about to ask a question,
22 sir?
23 MR.
ROOSCOLLINS: Is this room locked up at night?
24 CHAIRMAN
CAFFREY: Yes. If you want to leave your
25 things here, we will make sure it is locked.
0363
01 CHAIRMAN
CAFFREY: This meeting is adjourned.
02 See you 9:00 in
the morning.
