AGENDA TITLE: Resolution authorizing the Parks and Recreation staff, in conjunction with
Woodbridge Irrigation District to apply for a Sonar Fish Monitoring Project and
Program Grant
MEETING DATE: September 1, 1999
PREPARED BY: Parks and Recreation Director
RECOMMENDED ACTION: That City Council approve the resolution authorizing the Parks and
Recreation Staff in conjunction with Woodbridge Irrigation District to
apply for a Sonar Fish Monitoring Project and Grant and further authorize
the City Manager to execute the grant documents.
BACKGROUND INFORMATION: The City of Lodi and Woodbridge Irrigation District have been
asked by Fish and Wildlife Service (U.S.F.W.S.) to submit a grant to their agency for funding a sonar -
based fish counting system (mainly Chinook Salmon and Steelhead Trout). The grant includes
equipment, installation, training, testing and monitoring. This is a two-year grant project that, if
successful, will be administered by East Bay Municipal Utility District (E.B.M.U.D.) on a long-term basis.
There is no cost or oblioation to the City. The grant is in the amount of $361,000.00 and will initially be
administered by W.I.D. The project dovetails our Cal/Fed Project to build the new dam at Woodbridge.
FUNDING: No funding is required.

Re:
U.S. Fish and Wildlife Proposal
I have been working with Erwin Van Nieuwenhuyse from the Anadromous Fish
Restoration Program of the U.S. Fish and Wildlife Service (USFWS) to prepare
the attached proposal for submittal to USFWS. This proposal requests funding
for the installation and evaluation of sonar -based monitoring equipment near
Woodbridge Dam. It overlaps the request included in our most recent proposal
to CALFED, but USFWS has authority to fund projects beneficial to anadromous
fish through the Central Valley Program Improvement Act (CVPIA) Restoration
Fund, a separate funding source from CALFED.
I have given the proposal in draft form to Erwin for his initial evaluation, but in
order to officially submit the proposal, it must come from WID and the City of
Lodi. Please review the proposal and, if you agree, prepare and sign a joint
letter of submittal.
There is no time limit on this proposal, but the soonerwe submit it the better our
chances. If there is anything I can do to assist you, or if I can answer any
questions, please let me know.

Executive Summary
Project Title and Applicant Name
Project Title: Mokelumne River Juvenile Chinook Salmon Sonar -Based Enumeration Project.
Joint applicants: Woodbridge Irrigation District (WID) and the City of Lodi.
Project Description and Primary Biological/Ecological Objectives
The proposed project involves sonar -based counting of anadromous fish on the lower
Mokelumne River in San Joaquin County, California. At present, juvenile fish are counted using
screw traps. This project involves acquiring, installing, testing, and using sonar -based equipment
near Woodbridge Dam to automatically count juvenile anadromous fish (mainly fall -run chinook
salmon and steelhead trout). The sonar -based counts will be compared to existing counting methods
and evaluated to determine if the system provides sufficient accuracy at a reasonable cost to
substitute for existing methods.
Approach/Tasks
This is a 2 -year proj ect. The first year involves acquiring, installing, and testing sonar -based
monitoring equipment and training staff. Paul Skvorc, of Acoustic Research and Technology, is an
expert in this field and he will assist in calibrating the equipment and training project staff in its use.
The second year involves collecting a full season of data for evaluation. The tasks associated with
each year of the study are provided below:
Year One - Site Setup, System Configuration, and Statistical Design. Tasks during
the first year include acquiring equipment, selecting a site, quantifying the relationship
between probability of detection (PoD) and gas bladder length for postemergent chinook
fry, developing the project statistical design, training technicians, and preparing quarterly
and annual reports. •
Year Two - First Year of Operations. Tasks during the second year include testing the
statistical results of year one data; corroborating the PoD curve from year one and
corroborating year one statistical design with a corresponding statistical precision
estimate; preparing quarterly and annual reports; and analyzing and reporting total
project cost, cost per sample, and cost for various levels of precision or seasonal
estimates of passage.

Justification for Project Funding by the AFRP
This project is consistent with the Revised Draft Restoration Plan (Plan) for the Anadramous
Fish Restoration Program (AFRP) and is necessary to evaluate the improvements recommended by
the Plan. Specifically, the Plan calls for evaluating the effectiveness of restoration efforts on the
Mokelumne River, including "evaluat[ing] the effectiveness of pulse flows to facilitate successful
emigration of juvenile salmonids in the spring", and "evaluat[ing] and facilitating] passage of
spawning adult salmonids in the fall and juvenile salmonids in the spring" past Woodbridge Dam.
These evaluations will be more accurate if sonar -based monitoring is successfully implemented on
the lower Mokelumne River.
Budget/Time Line
The project is estimated to cost $361,000 over 2 years: $75,000 for material and equipment
costs, and $286,000 for service contracts. Equipment purchase and installation is scheduled to begin
in October 1999. The project is expected to be completed in September 2001.
Applicant Qualifications
The joint applicants for this project are WED and the City of Lodi, but the work will be
undertaken by Jones & Stokes Associates and Acoustic Research & Technology, contractors to the
joint applicants. The qualifications of these firms are presented below.
Jones & Stokes Associates. Jones & Stokes Associates has extensive experience with the
anadromous fisheries analysis and management throughout the, Central Valley. In addition,
Jones & Stokes Associates has direct experience working on the Mokelumne River, including the
preparation of an environmental impact report/environmental impact statement (EIR/EIS) on
implementation of the lower Mokelumne River Restoration Program (LMR -RP), which includes
actions to improve passage and screening conditions for anadromous fish in the lower Mokelumne
River.
Acoustic Research & Technology (Paul Skvorc) - Paul Skvorc was the fust person to design, build
and prove a sonar -based system capable of differentiating species of fish based on their frequency

Monitoring and Data Evaluation
The project is a monitoring effort, so monitoring of the project is not necessary. Data
collected by the sonar equipment will be processed and statistically analyzed to determine its
accuracy in counting juvenile anadromous fish. Following completion of the data collection, the cost
and accuracy of data acquisition will be analyzed and compared to existing data collection methods.
Local SupportlCoordination with other Programs/Compatibility with AFRP Objectives
This project was included in a grant proposal submitted to CALFED in April 1999. That
proposal was supported by the co-sponsors WID and the City of Lodi, East Bay Municipal Utility
District (EBMUD), San Joaquin Council of Governments, The Nature Conservancy, San Joaquin
Resource Conservation District (RCD), South Sacramento RCD, Sloughhouse RCD, Florin RCD,

Project Description
Project Description and Approach
The proposed project involves sonar -based counting of juvenile anadromous fish on the
lower Mokelumne River in San Joaquin County, California. At present, adult fish are counted by
EBMUD using video equipment installed in the fish ladder at Woodbridge Dam. Juveniles are
counted using screw traps. This proj ect involves installing, testing, and using sonar -based equipment
near Woodbridge Dam to automatically count juvenile anadromous fish (mainly fall -run chinook
salmon and steelhead trout). The sonar -based counts will be compared to existing counting methods
and will be evaluated to determine if the system provides sufficient accuracy at a reasonable cost to
substitute for existing methods.
The sonar -based counting equipment will be located just below Woodbridge Dam near the
current screw trapping site. The project's primary long-term goal is to provide a seasonal estimate
of the cumulative downstream passage of out -migrating juveniles, including recently emerged fry
and smolts. The first year's in -season goals will be directed toward identifying and ameliorating
site-specific problems and establishing a well-defined daily routine of data acquisition, processing,
analysis, and storage. Ultimately, the proj ect will feature at least two transducers, one on each bank,
insonifying the entire water column from bank to bank. The project will likely operate either
manned or unmanmed for — 24 hours per day 7 days per week — for the duration of the field season.
Data will be collated and processed in 24 hour increments. A given day's passage with associated
confidence intervals will be available the following day. Cumulative daily passage estimates will
be accumulated to seasonal passage estimates and run -timing curves.
Location or Geographic Boundaries of Project
The equipment will be located in the vicinity of Woodbridge Dam on the Mokelumne River
near the town of Woodbridge, but the project allows for the counting of all migrating fish in the
lower Mokelumne. The lower Mokelumne River is defined as the stretch of river between
Camanche Dam and the Cosumnes River.
AFRP Action/Evaluation Priority
The Revised Draft Restoration Plan for the AFRP (May 1997) includes recommendations
for several evaluations related to restoration efforts on the lower Mokelumne River: "evaluat[ing]
the effectiveness of pulse flows to facilitate successful emigration of juvenile salmonids in the
Woodbridge Irrigation District August 4, 1999

spring" and "evaluate and facilitate passage of spawning adult salmonids in the fall and juvenile
salmonids in the spring" past Woodbridge Dam. These evaluations are authorized under CVPIA
Section 3406(e)(3), "Measures to eliminate barriers to upstream and downstream migration of
salmonids"; and Section 3406(e)(6), "Other measures to protect, restore, and enhance natural
production of salmon and steelhead in tributary streams of the Sacramento and San Joaquin rivers."
CALFED has selected the lower Mokelumne River as a priority river for fish restoration
under the Ecosystem Restoration Program. CALFED, EBMUD, the U.S. Army Corps of Engineers,
and others are spending significant amounts of time and money studying ways to improve ecosystem
functions in that section of river. The existing methods for counting juveniles may not be
sufficiently accurate to allow firm conclusions regarding the effects on salmon and steelhead
populations to be drawn from these evaluations. If successfully implemented, the sonar -based
enumeration proj ect will allow the U.S. Fish and Wildlife Service (USFWS), California Department
of Fish and Game (DFG), National Marine Fisheries Service (LANES), and others to evaluate the
benefits or impacts of fishery restoration actions being undertaken in the lower Mokelumne River.
Expected Benefits
The current method for counting j uvenile anadromous fish, screw traps, counts only between
1% and 10% of the downstream migrants, and therefore provides an estimate of the number of
migrating fish with an error margin of +/- 80%. This method makes the measurement of the
expected effects on population of the various actions being undertaken on the river, including the
improvements to fish passage and fish screening being proposed as part of the LMRRP, very
difficult. The successful implementation of a sonar -based counting system can provide a much more
accurate estimate of population size. By installing this system prior to implementing any of
elements of the LMRRP, a baseline measure of population size cambe obtained, against which the
effects of the LMRRP can be measured. It also will provide a more accurate method for measuring
the effects of other ecosystem improvements including AFRP and CALFED Ecosystem Restoration
Program Plan (ERPP) actions.
Background and Biological/Technical Justification
In the early developmental stages, the project design will be focused on determining those
characteristics of the fish that reduce the PoD from one.
The theoretical minimum range resolution (which corresponds directly to the ability to detect
individual targets) is equal to 1/2 the pulse width. The actual range resolution is slightly larger than
the pulse width; how much larger is primarily a function of the quality of the hardware producing
the signal, the hardware receiving the signal, the techniques used to process the received signal, and,

to a lesser degree, the medium through which the sound propagates (in this case, the river).
Postemergent fry are small. In order to maximize spatial resolution the pulse width needs to be short;
however, sufficient power to effectively insonify the maximum cross section of the river is
maintained by lengthening the pulse width. When dealing with acoustically small targets, it is best
to determine at the site the pulse widths that will provide sufficient detection power and sufficient
spatial resolution for individual target detection. Because fish density (fish per unit volume of river)
will change as each season progresses, the PoD, as a function of pulse width, will change
correspondingly.
In order to get an initial estimate of the PoD in the early stages of fry outmigration, fish were
collected from the Woodbridge screw trap in mid-February and X-rayed to determine gas bladder
lengths (the gas bladder is the primary acoustic reflector.) Fitting a Weibull distribution to the
resulting data set suggests that there is a 90% chance that by February 11, 1999, approximately 75%
of the fish present had gas bladder lengths greater than 8 millimeters (mm) (Table 1). If a frequency
of 420 kilohertz per hour (kHz) is employed, it will have a corresponding 1/2 wavelength of
approximately 1.8 mm. Theory dictates that under ideal conditions (other physical properties of the
target and medium of propagation not withstanding), an object will reflect a pressure wave if the
diameter of the object, normal to the incident wave, is equal to or greater than Yz the wavelength.
(Actually it is the cross sectional area of the target normal to the incident wave, but in the case of
targets having cross sections that are not needle-like, the largest diameter is a convenient measure.)
In practice, the industry -recommended standard is that the object have a diameter, normal to the
incident wave, at least 10 times the Yz wavelength. As the ratio of diameter to % wavelength
decreases from 10:1, the PoD decreases correspondingly but not linearly. With a 1/x wavelength of
1.8 mm for 420 kHz, the 10:1 ratio suggests that under ideal conditions, the minimum target size for
a PoD of one is 18 mm. Table 1 illustrates that less than 1% of the fish in the February 11, 1999
sample have gas bladders in excess of 18 mm. However, the PoD does not plummet from 1 as the
diameter to '/x wavelength ratio decreases from 10:1. In fact, it remains near 1 until the ratio falls
below 5:1. (A prior exact probabilities are not obtainable because,of the complexity of unknown
site-specific physical characteristics.)

At this point, one might be tempted to increase the operating frequency of the system;
however, the higher the frequency the greater the attenuation of the projected pulse. Additionally,
as frequencies exceed roughly 200 kHz, attenuation reaches a signif=&t level and the sources of the
attenuation increase. Attenuation increasingly fluctuates more severely with small changes in
characteristics in the water, such as conductivity. The effect is a fluctuating insonified cross section.
Attenuation is easily compensated for mathematically; however, as the sonar system becomes more
sensitive to changes in the operating environment, the level of required onsite expertise increases.
Additionally, the need for human supervision of the system increases.
Woodbridge Irrigation District August 4, 1999

The best solution is to choose an operating frequency that minimizes attenuation and
maximizes the ratio of gas bladder length to wavelength for the fish of interest. Given the
availability of hardware capable of generating and receiving 420 kHz and the relatively short range
at the Mokelumne site, 20 kHz is a reasonable starting point. If compensating for 420 kHz
attenuation turns out to be a data acquisition and processing problem (the cost of technical expertise
exceeds budget constraints), other options can be explored. Those options include:
lowering the system frequency,
reducing statistical rigor (enlarging the confidence intervals around the passage
estimate), and
postponing initiation of the sonar until the gas bladders are of sufficient size to provide
the PoD value that is satisfactory for the level of precision required for the passage
estimate.
Proposed Scope of Work
This is a 2 -year proj ect. The first year involves obtaining, installing, and testing sonar -based
monitoring equipment and training staff. We will use Paul Skvorc of Acoustic Research and
Technology, an expert in the field, to calibrate the equipment and to train project staff in its use. The
second year involves collecting a full season of data for evaluation. The tasks associated with each
year of the study are provided below.
Year One - Site Setup, System Configuration, and Statistical Design
Select the site. Selecting the specific location for installation of the sonar equipment
includes determining the bottom profile and if bottom modification will be necessary,
and constructing the structures necessary to house the sonar equipment.
2. Quantify relationship between PoD and gas bladder length for postemergent chinook fry.
3. Develop the project statistical design. This includes establishing a daily sampling
schedule based on predetermined statistical precision criteria for the seasonal passage
estimate, onsite personnel requirements, offsite data processing and , analysis, and
incorporation of the PoD curve established under Task 2.
4. Train technicians.
5. Prepare quarterly reports.
Woodbridge Irrigation District August 4. 1999

10
6. Prepare annual report.
Year Two - First Year of Operations
1. Test statistical results of year one. Given the statistical design of year one, collect data
to determine if the established procedures yield consistent results with current season
environmental and biological conditions. If not, collect data for adjustment.
2. Corroborate PoD curve from year one.
3. Corroborate year one statistical design with corresponding statistical precision estimate.
4. Prepare quarterly reports.
5. Prepare annual report.
6. Analyze and report total project cost, cost per sample, and cost for various levels of
precision or seasonal estimate of passage.
It is likely that the project will ultimately be staffed with three technicians whose primary
function is to collect and preserve data acquired by the sonar system. In addition, they will perform
upkeep and preventive maintenance on the sonar system and associated support equipment. The
project leader will be responsible for routine daily data processing, analysis, dissemination, and
archiving. The project leader also will supervise the technicians and troubleshoot system problems
directly observed or identified by the technicians. The project leader will be responsible for the
technical integrity and statistical evaluation of the data at all levels. The leader will also be
responsible for maintaining the operational capabilities of the sonar system and the support
equipment and facilities. In the initial phases of the project, the project leader will conduct or
supervise data processing and analysis. The project leader will be responsible for developing site
specific operational protocols, writing required periodic reports, and conducting presentations when
necessary.
Monitoring and Data Evaluation
During the first year, the project will be operated on a normal 8 -hour work day. This day
may start just prior to sundown in order to be operational at the time of day of maximum passage.
Sonar sampling will commence at the start of the hour and continue for 20 minutes on one bank,
followed by a 5 -minute break to prepare for sampling on the opposite bank. Sampling on the
opposite bank will commence at 25 minutes past the hour and continue for 20 minutes. This will
be followed by a 15 -minute period of quiescence, after which the sampling sequence will commence
Woodbridge Irrigation District August 4, 1999
Sonar -Bared Monitoring on Mokelumne River PS99_179
11
again at the top of the hour. This cycle will continue for the full 8 hours, after which the data will
be stored and prepared for transport back to the office for analysis.
The sonar system will be transmitting at eight pings per second for 40 minutes per hour, at
least 8 hours per day. Each ping will have a range resolution of approximately 8 centimeters (cm).
If the total range per bank is 15 meters, the total number of target acquisitions possible per ping is
approximately 190. Each valid echo will provide no less than 9 and as many as 15 separate
parameters to be recorded. Each target should provide at least eight echoes. Therefore, in one 8 -
hour sampling period, there is the potential for 2.1x109 data bits (8 x 60 x 40 x 8 x 190 x 9 x 8) that
have to be filtered, stored, and processed. The following references provide thorough detail on the

The joint applicants for this project are WD:) and the City of Lodi, but the work will be
undertaken by Jones & Stokes Associates and Acoustic Research & Technology, contractors to the
joint applicants. Qualifications of these firms are presented below.
Jones & Stokes Associates
Jones & Stokes Associates has extensive experience with the anadromous fisheries analysis and
management throughout the Central Valley of California. Jones & Stokes Associates has conducted
large-scale systemwide analyses of impacts on fisheries of implementation of both the CVPIA and
the CALFED Bay -Delta Program. In addition, Jones & Stokes has direct experience working on the
Mokelumne River, including the preparation of an EIR/EIS on implementation of the LMRRP,

near Woodbridge Dam.
Acoustic Research & Technology (Paul Skvorc)
Paul Skvorc's sonar experience dates back to 1970 when he was a US Navy Sonarman aboard
nuclear submarines. Paul received a B.S. in zoology in 1978 and an M.S. in ecology in 1980.
Throughout his undergraduate and graduate work, Paul was involved in fisheries sonar ranging from
crappie, shad, and largemouth bass in Kansas reservoirs to arctic grayling, lake trout, and arctic char
in alpine lakes on the arctic coastal plain in Alaska. Paul pursued an interdisciplinary doctorate in
electrical engineering, physics, and fisheries science at the University of Alaska. His thesis title is
"The Use ofBroadband Sonar for Fish Species Differentiation." Paul was the first person to design,
build, and prove a sonar system that was capable of differentiating species of fish based on their
frequency domain signature. Paul started to work for the Alaska Department of Fish and Game
(ADFG) prior to defending his thesis. Paul worked for the ADFG for 11 years as the head of the
Sonar and Technical Services Group in the Division of Commercial fisheries. During that 11 -year
period, he pioneered several new fisheries acoustics techniques and developed the first statistical
methods for determining the precision of riverine fisheries sonar. Paul was also the State of Alaska's
expert in hydroacoustics on the Joint Technical Committee of the US/Canada Salmon Treaty
negotiations, and has assisted the Canadian Government in starting three separate fisheries projects;
one on the Yukon River in the Northwest Territory for chinook salmon, one on the Arctic Red River
in the Northwest Territory for broad white fish, and one in the Fraser River in British Columbia for
