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.
