THEREUPON,

RONALD MIERAU

being by me first duly sworn to tell the whole truth,

as hereinafter certified, testified as follows:

DIRECT EXAMINATION

BY MS. NASH:

Q. Mr. Mierau, I'm Beverly Nash. I'm counsel

for the United States in this litigation.

We're here to find out about the Water

Management District's computers, and the data

that's on the computers, and how it's formatted.

You were selected by the district as a

representative having knowledge concerning one or

more of the categories of inquiry which we're

interested relating to the computers.

Have you been shown that list of

categories?

A. Yes, I have.

Q. Do you know which ones you're able to

respond?

A. I believe it's 2, 3, and 6.

Q. What is your present title or position?

A. I'm the director of the operations

** 6

division.

Q. And that's in which department?

A. The operations and maintenance department.

Q. And what are your responsibilities as the

director?

A. I'm responsible for physically moving the

water around to balance flood control, water

supply, and environmental needs. We do that

through operation of gates and pump stations.

Q. And how long have you been director of the

operations division?

A. Since April 1990.

Q. Have you had other positions at the Water

Management District?

A. Yes.

Q. What positions?

A. Previous to that, I was interim director

of the water quality division for a period of

approximately six to nine months. Prior to that, I

was the director of the data management division.

Q. What were your responsibilities as the

director of the water quality division?

A. Essentially, I was performing

administrative tasks to fill-in while they were

recruiting a qualified person with both

** 7

administrative and water quality skills.

Q. How long were you director of the data

management division?

A. I don't recall the exact length of time.

I know it was several years.

Q. And what were your responsibilities in the

data management division?

A. To coordinate the data acquisition and

archival of hydrologic information.

Q. What's your educational background?

A. I have got a bachelor's degree in civil

engineering from the University of Nebraska; and a

master's degree from Colorado State University in

water resources engineering.

Q. To whom do you report in the operations

and maintenance department?

A. Alan Hall.

Q. Do you have employees that work for you?

A. Yes.

Q. How many?

A. Approximately 20.

Q. What is the general nature of the

positions that work for you?

A. I have got some control room personnel

which are technicians and supervisors. We have a

** 8

24-hour shift that monitors the real time

information to determine hydrologic conditions at

any time and operate the gates under emergency

conditions, that's the majority of the staff.

I have currently two computer programers

and one supervisor. Then, I've got a meteorologist

and a temporary meteorologist, and one person

that's working currently on artificial intelligence

systems.

Q. What computers are utilized by the

operations division?

A. We have got a pair of Modcomp computers,

which do our real time data acquisition and

control. We have got several PCs, personal

computer type equipment. That's currently all that

-- the only types that we use directly.

We access also the information on our

Cyber in our system for historical information,

historical hydrologic information.

We had a prototype artificial intelligence

system developed on Symbolics equipment, and we are

not using that anymore.

We will be looking for some other type of

computer equipment to put that platform on, but

that hasn't been decided yet.

** 9

Q. What software is utilized on the Modcomps?

A. That's custom software plus the Modcomp

operating system.

Q. Is that developed by Modcomp or within the

Water Management District?

A. The software applications were developed

within the Water Management District and on

contract to -- by a contractor for the Water

Management District.

Q. Do you know who within the Water

Management District developed the software?

A. Rudi Vyhnanek was in charge of

supervising that. I believe that was -- the

original system was developed considerably before I

got involved with the operations department.

Q. And do you know who the outside contractor

was?

A. I don't recall.

Q. What's the software packages utilized on

the PCs?

A. The PCs routinely use Word Perfect,

Symphony, Picture Perfect, some communication

packages. There may be other less prominently used

ones. Most of those are standard software packages.

Q. Does the division utilize any in-house

** 10

software packages?

A. I don't believe that's the case. There is

an application that we use fairly frequently that's

written on a GEM system that was done in-house

several years ago. It wasn't done within the

division, but we utilized it frequently. That

application accesses data from both our Modcomp --

our -- a summary of the information on Modcomp,

which is stored on Micro VAX computer. I'm sorry.

I neglected that one -- and there we have an Oracle

data base established as an interim type thing

until we get a better data base system developed

to handle that. They had also linked up the Cyber

computer, so we can get merge historic and current

hydrologic information and plot that up through the

graphics package that was -- that application for

that graphics package was developed in-house.

Q. Do you know who developed it?

A. Paul Wright.

Q. Are reports or analyses done of the data

that comes in to the operations division?

A. We routinely make reports that our board

of directors use, our governing board uses, for

informational purposes on a monthly basis called a

water conditions report.

** 11

Q. And what's the data base that's utilized

to do the water conditions report?

A. It comes from a combination of a set of

paper files, which we log our daily water readings

on from our Cyber data base, which is DB Hydro,

again, the historical hydrologic information and

the summary of our Modcomp information, which is

kept on our Micro VAX.

Q. The summary of information you're talking

about being kept on Micro VAX, is that data that's

been processed in some fashion?

A. It's processed through the Modcomp and

gives us information, like, water levels -- the

most critical ones that we use for that report are

water levels, we use gate openings and -- to

compute the flow with. Gate openings aren't

reported directly in the reports. We do compute

the flow, which is used -- indirectly requires the

gate openings, pump rpms, and water levels, in

conjunction with rating curves.

Q. You indicated that you have an employee

working with artificial intelligence systems?

A. Yes.

Q. What is the nature of those systems?

MS. STOLLMAN: This will be the

** 12

computer systems.

A. The computer system, right now we are

still in the process of selecting a computer system

for this to work on. We have originated a

contract. We call this artificial intelligence

system OASIS. And I'm not sure exactly what the

acronym means right now. It's something like --

well, I'm not sure exactly what it means.

Q. (By Ms. Nash) Who developed OASIS?

A. That was originally started under Gary

Goforth, who is no longer with the division. We

had a consultant at that time who did some

prototype work for us. Paul Ryan, which is

currently a programer with our system, did some

work on it; and it's been devaluated as a prototype

model for our next phase, which we are getting in

to now, by two different consultants.

Q. Do you know who the consultant was that

did the prototype work?

A. I don't recall.

Q. You indicated that part of the

responsibilities of the division is to look at

environmental needs or the operation of the gates

in the pumping stations?

A. We try to balance --

** 13

MS. STOLLMAN: Is your question

limited to his work that he does on the computer

systems?

MS. NASH: Well, the computer systems

are utilized to operate these. And I'm trying to

find out the perimeters that they consider when

they're doing the operation.

MS. STOLLMAN: And what was your

question again? Could you read it back for me?

(WHEREUPON, the requested testimony

was read back by the court reporter.)

MS. STOLLMAN: To the extent that

this is work on the computer system, you can answer

that.

A. We don't establish the environmental

criteria. There are times when, within our

operational policy, that it's necessary to balance

environmental concerns with flood protection and

water supply needs.

Q. (By Ms. Nash) Who establishes the

environmental criteria?

A. That's generally done in coordination with

--

** 14

MS. STOLLMAN: I would object to that

question unless you're asking about the

environmental criteria done on the computer.

MS. NASH: They may well be, but let

him answer the question, so I can find that out.

MS. STOLLMAN: Well, I'd like to --

MS. NASH: This is a background

question, Katharine. It is a background question

that I am entitled to have asked to find out who

establishes the criteria.

MS. STOLLMAN: To the extent the

criteria are established on the computer systems,

you may answer the question.

A. The criteria aren't currently established

on the computer systems. They're done through

operational rules that haven't currently been

computerized.

Q. (By Ms. Nash) And who's developed the

operational rules? What office or division?

A. These operational rules are based on Corps

of Engineers criteria, first of all, for operation

of structures and the original project design.

There have been modifications in the past that have

gone through a series of multiagency review, and

regulation schedules have been developed on that

** 15

basis and modified on that basis.

Q. When you were talking about the artificial

intelligence project, do you know what

environmental considerations are taken into account

in that project?

A. That's not currently a function of the

artificial intelligence system. The phase of the

artificial intelligence system we're working on

currently is an intelligence warning system. This

conceptually will give us active warnings on

whether we have information that makes sense

hydrologically, first of all, to apply some sort of

intelligence criteria to the incoming data stream

to verify that this is reasonably accurate

information coming back there. There are times

when senses malfunction and we need to know that.

In addition to that --

MS. STOLLMAN: I think this is

nonresponsive to your question. If we could have

the question read back.

MS. NASH: He's explaining what the

artificial intelligence project considerations

are. It is responsive to the question. He can

finish the answer.

MS. STOLLMAN: I would like to have

** 16

the question read.

(WHEREUPON, the requested testimony

was read back by the court reporter.)

MS. STOLLMAN: The question has been

asked and answered.

MS. NASH: He was finishing -- yes, I

want him to finish the answer he was giving. He

was explaining what the system is currently

considered.

MS. STOLLMAN: Well, he answered

your question that's not currently a part of it.

If you have another question, please ask it.

MS. NASH: Fine.

Q. (By Ms. Nash) What is the current phase

of the system looking at?

A. The current phase of the system is

providing an intelligence warning system to help

detect sensory malfunctions and to project whether

our current operations are going to meet our -- our

current objective is for maintaining water levels

in the areas over which we have control.

Q. Is the operations division the one that

actually receives the raw data from the remote

** 17

sensing locations?

A. Through our telemetry system, we do

receive directly those sensory readings. In

addition, we receive reports from our field

stations on sensors that aren't currently

accessible through the computer. They come in over

radio or paper forms.

Q. And where is that data stored that comes

in?

A. Which data?

Q. The telemetry data initially?

A. The telemetry data is initially stored on

Modcomp computer system then is transferred to our

Micro VAX Oracle data base, which I described

previously as a temporary situation, and nightly is

moved to the preprocessing system under data

management where it goes through further

verification process; and finally, ends up residing

in some reform on DB Hydro, which is also on the

Cyber system at the current time.

Q. What is the further verifications that's

done in the preprocessing system?

A. They check -- the data management

division checks -- at least during the time where

I was actively involved with this process, they

** 18

check for continuity in data sets, continuity of

transmissions to verify whether we really had

continuous information as was indicated on the

files to apply a rate of change checks and to apply

a limit checks in terms of exceeding reasonable

maximum minimums. In addition to that, a cross

station performance was checked manually through

plots of this data.

Q. Is the data that was received in paper

form or over radio put into the computer?

A. I don't believe all of it was put into the

computer, but the more critical ones that people

use all the time are.

Q. When you say, "more critical," are you

referring to more critical field stations or more

critical types of data?

A. More critical types of data. There are

some types of data that -- some locations in which

data is needed periodically, not on a continuous

basis -- that information hasn't currently been in

access. Particularly those that are incurred in very

infrequent intervals simply haven't been provided

for in our electronic system.

Q. Do you know the nature of the data that's

not being computerized?

** 19

A. In general it's what we call staff gauge

readings in very remote sites that we have very

little operational control over. By "staff gauge

readings," I mean readings that are manually

observed from some -- you might say, "ruler," some

way of measuring water levels someplace. Generally

they're very remote and are taken manually. We

don't have any electronic means of acquiring that

information now.

Q. You indicated that incoming data is

checked for rate of change or limit checks. What

procedure is followed if the data exceeds the

limits?

MS. STOLLMAN: Is your question

finished?

MS. NASH: Yes.

MS. STOLLMAN: This would be limited

to computer procedures which are followed.

A. Again, I'm not directly involved in that

process at the current time. That process is being

carried on in the data management division.

Q. (By Ms. Nash) What was the process when

you were in data management?

A. When I was in the data management

division, we looked for a physical cause for that.

** 20

If a physical cause -- if it was determined that

that rate of change really was realistic -- because

our estimates of rate of change are based on

previous experience -- if our professional

hydrologist determined that these rate of changes

were really reasonable, then, we'd change the

limits under which these flags would be made.

If it was determined that it was an

instrument malfunction, which caused the rate of

change problem, then, a probable cause for that was

sought and values were estimated, if possible, to

correct that situation. If it wasn't possible to

correct that rate of change situation with

reasonable confidence, then, those values were

flagged as missing or unavailable.

Q. Are there back-up procedures for the

incoming data?

A. You're referring to which data now?

Q. The raw data that comes in, is there a --

A. From which source?

Q. From any source?

A. The raw data that comes in through the

Modcomp system is backed up on tape on a daily

basis and then goes through the additional

procedures that I mentioned earlier.

** 21

MS. STOLLMAN: Can we go off the

record for a moment?

(WHEREUPON, there was a discussion

held off the record.)

(WHEREUPON, the requested testimony

was read back by the court reporter.)

Q. (By Ms. Nash) Do you know the retention

period for these back-ups tapes?

A. No.

Q. Do you know who would know?

A. Rudi Vyhnanek.

Q. When the data winds up in DB Hydro, do you

know whether that's also backed up?

A. That is backed up.

Q. Do you know the procedure for that

back-up?

A. I don't recall specifically.

Q. Do you know who would know?

A. Bill Hall.

Q. Do you know the retention period for that

back-up?

A. To my knowledge, that was to be retained

** 22

permanently.

Q. Do you know the period of record for the

data in DB Hydro?

A. Yes.

Q. What is that?

A. It dates back to, in some cases, the early

1900's.

Q. Is there a listing of which locations the

data goes back that far?

A. There is a listing available of the dates

for all information. It's not -- to my knowledge,

there is not a list chronologic or sorted by period

of record available.

Q. Where is that list available?

A. From data management.

Q. Does the list have a name?

A. I don't recall what the name of the list

is.

Q. Who would know?

A. Rob Startzman.

Q. When you were in data management, what

computers were utilized?

A. We utilized the Modcomp, some PCs, and we

did access the Modcomp -- or I'm sorry -- the Micro

VAX, which has the Modcomp data summaries on it, as

** 23

through the procedure I mentioned earlier.

Q. And data management is the keeper of the

archive of hydrologic data?

A. That's correct.

Q. And that's in DB Hydro?

A. That's correct.

Q. Is there other hydrologic data that data

management maintains?

A. Would you clarify that question?

Q. Is there hydrologic data maintained by

data management that's not in DB Hydro?

A. Not to my knowledge. I'm sorry. The DB

Hydro does not contain a summary of gate

information.

Q. Where is that summary of gate information?

A. There is another source of files within

data management called Breakpoint Archive System.

The gate information is stored in that area.

Q. What else or what is contained in this

summary of data information that's not in DB Hydro?

A. Gate opening information.

Q. Anything else?

A. And pump rpm information.

Q. I'm sorry?

A. Pump rpm.

** 24

Q. While you were in data management, were

analyses done in that division on the data in DB

Hydro?

A. The primary function of data management

was to maintain accurate archives of that

information and the collection?

A. It was required to do some analysis on

that historical information to further this

validation process.

Q. Can you elaborate on what that analysis was?

A. Things like comparing mean values from

year to year, reasonable ranges in fluctuation.

Q. Anything else?

A. Some -- it was necessary to develop some

feel for intrastation correlations, if not

statistically, at least, qualitatively.

Q. Are these analyses that were done stored

anywhere?

A. What's that?

Q. Are the analyses that were done stored

anywhere?

A. Not to my knowledge.

Q. Were the analyses provided to anyone

outside the data management division?

A. Not to my knowledge.

** 25

Q. Are you aware of any computer water

quality analyses being done as part of the SWIM

Plan?

MS. STOLLMAN: Again, it would be

analyses done on the computer systems.

MS. NASH: That's what my question

asked.

A. There was some work -- some analysis done

in the water quality division on water quality

perimeters for the SWIM Plan.

Q. (By Ms. Nash) Do you know who did that

analysis?

A. I believe Dave Soballe did at least part

of it.

Q. Do you know what water quality perimeters

were looked at?

A. Phosphorus was one.

Q. Do you know of any others?

A. I believe nitrogen was also analyzed, but

I'm not certain about that.

Q. Do you know where the results of these

water quality analyses are?

A. Of the analyses or of the records? Would

you clarify the question, please?

Q. Yes. You indicated that Dave Soballe did

** 26

some analyses as part of the SWIM, and my question

was, where are the results or where are these

analysis stored and located?

MS. STOLLMAN: Are you asking what

computer system they're stored and located on?

MS. NASH: If that's where they are.

A. I don't know that the analyses are stored

on a computer. The results were incorporated in to

the SWIM Plan.

Q. (By Ms. Nash) Who would know?

A. Dave Soballe.

Q. Do you know whether any computer water

quality analyses were done for the Nutrient Removal

Project?

MS. STOLLMAN: You can answer if you

know.

A. I don't know that answer to that one.

Q. (By Ms. Nash) Do you know whether any

computer water quality analyses were done for

Everglades National Park outstanding natural

resource water standards?

A. I'm not aware of the analyses that went on

in that process.

Q. Do you know who would know?

A. Tom Fontaine.

** 27

Q. Do you know whether any computer water

quality analyses were done for state water quality

violations?

A. I don't know.

Q. Do you know whether any nutrient budget

analyses have been done for the Everglades

Agricultural Areas?

A. I'm not aware of any.

Q. Do you know whether any nutrient budget

analyses have been done to the Water Conservation

Areas?

A. I don't know.

Q. Do you know whether any nutrient budget

analyses have been done for Everglades National

Park?

A. I don't know.

Q. Do you know whether any water quality

trend analyses have been done for the Everglades

Agricultural Area?

MS. STOLLMAN: I don't want you to

speculate. You can answer if you know.

A. No, I don't know.

Q. (By Ms. Nash) Do you know whether any

water quality trend analyses have been done for the

Water Conservation Areas?

** 28

A. I don't know.

Q. Do you know whether any water quality

trend analyses have been done for Everglades

National Park?

A. I don't know.

Q. Do you know whether any computerized water

quality analyses have been done for establishing

best management practices in the Everglades

Agricultural Areas?

A. No, not that I know of.

Q. Do you know who might know?

A. I presume Tom Fontaine may know. Tony

Federico is probably a better source than Tom

Fontaine.

MS. NASH: I have no further

questions.

CROSS-EXAMINATION

QUESTION BY MR. RICHARDS:

Q. Mr. Mierau, my name is Joe Richards. I

represent the cities of Belle Glade and Clewiston.

You talked about the Breakpoint Archive

System?

A. Uh-huh.

** 29

Q. How does one access this system?

A. To my knowledge --

MS. STOLLMAN: I don't want you to

speculate. If you know how the system is accessed,

you may answer.

A. At the time that I last accessed it, when

I was involved in that system, most people in your

position would request a period of record from data

management in the form of a listing.

Q. (By Mr. Richards) Pardon me?

A. In the form of a listing for specific

station and period of record. There is a lot of

information on that within that system, so to --

you have to get fairly -- it was necessary to get

fairly specific in the request, otherwise, you'd

simply be overwhelmed with the amount of

information that would come back.

Q. Is it possible to obtain information from

this system in the ASCII format?

A. Yes. At the time that I was involved in

it, there was.

Q. And you can access the information by a

specific structure or period of time?

A. By a specific sensored name and time.

Q. Is there a listing of sensored names?

** 30

A. Yes.

Q. Where would that listing be?

A. In the data management division.

Q. Does it not have a name?

A. There's a computer procedure that can be

used to develop this list of names and that

procedure is called STGPOR.

Q. Do you know who is responsible for

maintaining this Breakpoint Archive System?

A. Data management division. Rob Startzman

is the director of the data management division.

Q. Do you know what computer it's contained

on?

A. It's currently on the Cyber system.

Q. And you mentioned that the data management

division performs some annual mean comparisons and

some other analysis. Do you know if these analysis

are used to change data values?

A. Normally, they're not used to change data

values. They're used to form a picture for the

hydrologist on what is reasonable for reviewing the

data for accuracy.

Q. And these hydrologist would then make a

decision on whether to change data values?

MS. STOLLMAN: I object to that

** 31

question. I don't think that's relevant. I don't

think that's part of this witness' knowledge what

he's here to testify about today.

MR. RICHARDS: He was director of

data management. He's testified about these

analyses and the purpose they're used for, and I'm

just trying to find out, you know, what effect that

has on what is contained in their computers.

MS. STOLLMAN: Could you repeat your

question, please?

MR. RICHARDS: Would you read it

back?

(WHEREUPON, the requested testimony

was read back by the court reporter.)

MS. STOLLMAN: Mr. Mierau is not

currently in that department. He can answer to the

extent that he would be aware of the computer

procedures at the time he was there, but that may

not be the case now.

Q. (By Mr. Richards) Please answer to the

best of your knowledge.

A. There -- occasionally, it was possible to

make fairly reliable estimates to change numbers so

** 32

that they were more realistic.

One way, as an example, that this could

occur was through ASCII transmission of data, you

could gain digits. Let's say, the water levels

were in the range of 14 or 15, all of a sudden you

get one value that reads 114 or 115. There is a

good possibility that in the transmission of this

data, you picked up an erroneous bid coming in,

which caused this type of an error. In that

instance, the number would be changed from the 114

down to the 14 and tagged with an estimated value.

Q. (By Mr. Richards) Are these estimated

values indicated in some way on the data base?

A. Yes, they are.

Q. How are these estimated values flagged?

A. Each value has a quality -- each value has

a time value and a quality tag associated with it.

Q. And who at the district would be presently

most knowledgeable as to this process you just

described?

A. Rob Startzman is in charge of that

procedure. He may have delegated some people that

are more knowledgeable to do the actual procedure.

Q. Do you know whether there is any written

guidelines or policies on this process?

** 33

A. Not to my knowledge.

Q. Are there any informal policies or

guidelines?

A. During the time I was involved with this

process, that type of information had to be -- when

changes were made to actual data values, those

changes had to be cleared through myself or another

qualified professional hydrologist.

Q. When it was cleared through yourself, you

were director of data management at that time?

A. That's correct.

Q. Do you know how frequently those changes

are needed to be made?

A. Changes were made to data values very

infrequently. If the data values were totally

unreasonable, it was much more likely that those

values would be tagged with another type of field,

which means -- which was an "M" for missing

information.

Q. In regard to the artificial intelligence

system you described earlier, you mentioned that

the system is designed to detect if the operations

meet the objectives. What objectives would this

be?

A. That is still under a development process.

** 34

Q. What objectives will there be?

MS. STOLLMAN: I would object to this

question. He can answer what objectives there are

currently in development, but the answer may not be

complete as to all objectives that could be

developed in the future.

Q. (By Mr. Richards) To your knowledge.

A. One of the objectives that we're looking

at implementing is to have target water levels,

which meet our expectations, and compare those

against trends which are currently developing from

our current operational decisions.

Q. Any others?

A. That's the primary mode right now.

Q. Do you know whether there are computer

records of the regulation schedules for the water

conservation areas?

A. Computerized regulation schedules, is

that what's --

Q. Yes.

A. Are those available?

MS. STOLLMAN: What was your

question? Could you repeat it back, please?

Q. (By Mr. Richards) Does the district

possess a computerized regulation schedule for the

** 35

Water Conservation Areas?

A. I would have to speculate on that.

MS. STOLLMAN: I don't want you to

speculate. If you know, you can answer the

question.

A. I'm not positive.

Q. (By Mr. Richards) Who would know whether

their regulation schedules are contained on

computer?

A. If they are contained on the computer,

Jorge Marban would be the most probable source for

knowing that.

Q. Do you know whether there are computer

records of how a particular regulation schedule was

followed for a particular year?

MS. STOLLMAN: Again, you can answer

if you know. I don't want you to speculate.

A. Well, would you rephrase that, please?

Q. (By Mr. Richards) Are there computer

records of how a regulation schedule was followed

for a particular year?

A. There are historical archives which

indicate what actual water levels were.

Q. Where would those historical archives be

contained?

** 36

A. They're contained in DB Hydro and in

detailed form within the Breakpoint Archive

System.

Q. Do you know whether the operation and

maintenance manuals prepared by the Corps of

Engineers are obtained in a computer format?

A. Not to my knowledge.

Q. Do you know, does the district possess

discharge ratings curves for the different

structures?

A. The district possesses computerized

discharge ratings curves for some structures.

Q. Which structures?

A. I don't recall the names of all those

structures. There is quite a few. There is a

considerable number.

Q. Do you have computerized discharge ratings

curves for the S5A structure?

A. Yes.

Q. S6?

A. Yes.

Q. S7?

A. Yes.

Q. S8?

A. Yes.

** 37

Q. S2?

A. I believe the USGS has computerized

discharge equations for S2.

Q. How about S3?

A. The same situation on S3. The district

also has -- on the case of S3, the district also

has a computerized discharge equation, but that's

not used for official records. The USGS maintains

the official records at that station.

Q. And S4?

A. I'm not positive about S4.

Q. S150?

A. The district has computerized equations

for S50 -- S150. I'm sorry.

Q. How about S9?

A. The district has a computerized equation

for S9.

Q. And where are these maintained?

A. At the time I was in data management, they

were maintained in a production program called E034,

E034.

Q. Do you know whether these discharge rating

curves are verified for accuracy?

A. Yes.

Q. Do you know how often?

** 38

A. There is currently an effort to verify all

of these equations through stream gauging.

Q. That is an ongoing process right now?

A. That is an ongoing process right now.

Q. Do you know when the last time that the

discharge rating curves were verified?

A. For which structures?

Q. S5A.

A. S5A has some recent measurements -- I

believe last month, maybe some this month.

Q. And before that, do you know when it was

verified?

A. There was some question posed as to the

reliability of the discharge equations at that

structure earlier this year, and I believe the

ratings were -- stream flow measurements were

started as soon as the water was available this

year, which, I believe, was in late May or early

June.

Q. And for structure S6, when was the last

time?

A. Also, I know there is at least one -- at

least one measurement and perhaps several

measurements since water was available between June

and the current date.

** 39

Q. And S7?

A. Same situation on S7.

Q. S8?

A. Same situation on S8.

Q. S150?

A. I'm not sure when the last stream flow

measurement was made on S50.

Q. S150?

A. S150, I'm sorry. I don't believe there

was any made this year.

Q. What about S9?

A. There has been at least one discharge

measurement made at S9, during this same period,

since water was available this year.

Q. In the past were these verified on any

kind of routine basis?

A. The USGS -- on the stations that the USGS

was involved in, they made measurements on a

frequency which they felt was adequate to maintain

confidence in the rating curves.

The Water Management District did not

follow procedure where they routinely verified the

rating curves.

There was substantial effort, after the

structures were initially established to develop

** 40

rating curves and flow measurements. Once those

were verified, it was assumed that these curves

wouldn't change substantially. This was verified

periodically by spot measurements at stations -- at

some stations.

Q. Do you know which stations?

A. I don't know.

Q. Besides the S3 and S2, what other stations

are USGS responsible for?

MS. STOLLMAN: You can answer if you

know. I don't want you to guess.

A. Would you be more specific in terms of

area or -- I may be able to help someone there.

Q. (By Mr. Richards) In the Everglades area?

A. In the Everglades Agricultural Area?

Q. Okay. Let's start there.

A. The USGS is responsible for the official

records on S5A, S2 and S3, and the associated

revenue flow structures.

Q. What about the S10 structures?

A. The S10 structures are the responsibility

of the Corps of Engineers. I'm not positive, but

the USGS may be involved in that procedure through

contract with the Corps of Engineers, but I'm not

positive on that.

** 41

Q. How about the S11 structures?

A. The same situation with S11.

Q. And the S12?

A. The S12, the USGS computes the flow

for the Corps of Engineers. They also give us

access to that information. I think the National

Park Services is also involved in funding that

station.

Q. When you were the data base management

director, were you aware of any data files lost

from the system?

A. No.

Q. Are you aware of any data lost from the

operations division computers?

A. No. I am sorry. There is times when our

communication system breaks down and we have no

provision at the current time for on site storage

of the telemetry system information. And during

the times that our transmission facilities don't

work, data is lost.

Q. Is that lost data somehow indicated in the

historical archive?

A. That is one of the functions of the data

management division to insure that all those

periods when we weren't receiving information from

** 42

the Modcomp system that those are flagged as

missing periods.

Q. Do you know what individual would be most

knowledgeable as to the discharge rating curves and

where they're maintained?

A. "Most knowledgeable," is sometimes

difficult to put a handle on. As for myself, I

have some knowledge of that. I'm sure Rob

Startzman would have some knowledge of that.

Q. Do you know who performs the

verifications?

A. Data management division.

Q. Do you know who in the data management

division?

A. I believe that the assignment for

verification of information is distributed among

several peoples.

Q. Do you know who those people are?

A. I would suggest talking -- I would suggest

Rob Startzman is the source for those personnel

assignments.

Q. Do you know at what points or steps in the

transfer of data between computers the transfer is

done by ASCII transfer?

A. Would you repeat the question, please?

** 43

Q. At what points or steps in the transfer of

data between computers is the transfer done by an

ASCII transfer?

A. To my knowledge, all the transfers between

computer systems are done in ASCII mode.

Q. Are transfers ever performed by using what

is known as an "error free protocol"?

A. I'm not sure what an "error free protocol"

is.

Q. Are the transfers done over the network?

A. The transfers are done over the network.

MR. RICHARDS: Thank you. I have no

further questions.
