EXECUTIVE SUMMARY

A 12-month biological monitoring study was conducted during 1987 at

Dun.ldrk Steam Station on La.1ce Erie in fulfilJJnent of agreements reached

with NYSDEC as referenced in February 19, 1986 letter from Mr. Edward G.

Horn (NYSDEC) to Mr. Joseph Miakisz (NMPC). Objectives of the study

included assessments of 1) the composi tion and abundance of

ichthyoplankton entrained during April-August, 2) COI'IpOSition and

abundance of aquatic organisms iIrpinged on recently installed Beaudrey

traveling screens, 3) viability of iIrpinged fish removed fran the

screens, and 4) efficiency of collection of inpinged fish fram tlle spray

wash and Aquaguard debris removal systems. The objectives were aimed

particularly at evaluating the effect of the dual-fleM Beaudrey traveling

screens on the abundance and viability of inpinged fish, in terms of

potential benefits of retrofitting a fish return system.

The eggs and larvae of 23 taxa were entrained during 1987. MinnCMS,

which included emerald and spottail shiners, accounted for over 60

percent of the entrained eggs. Rainbow smelt accounted for 56 percent of

the entrained larvae. Eggs and larvae were most abundant in June. The

greatest densities occurred during a June 9 storm event. Egg and larval

entrainment in 1987 was reduced fran 1976 and 1982 levels, particulary

for a forrrerly dominant species, the gizzard shad.

Total iIrpingem:nt, as recovered fram the Aquaguard debris ranoval

systems and adjusted for collection efficiency, was estimated to 

approximately 14.8 million fish in 1987. This estimate was nearly twice

that of 1982-1983 (8. 5 million) and seven times that of 1975-1976 (2.

million) . Total biomass of target fish species iIrpinged during 1987 was

53, 266 kg, which was less than the 93, 984 kg impinged during the 1982-

1983 study. The decrease in bianass was attributed to fewer gizzard shad

in 1987, but neither the 1982-1983 estimate nor the 1987 estimate include

the wei~lt of emerald shiners. Emerald shiners numerically composed 49

percent of the 1987 impingeroont, and only 4 percent of the 1982-1983

i1I1pingernent. An additional 8. 0 million fish (not adjusted for collection

efficiency) were estilnated to have passed through the Aquaguard system of

Screen.1'J.ouse 2. Recirculation of small fish that pass through the
Aquaguard system and return to the forebay may overestimate the

proportional abundance of the post-Aquaguard catp)nent of Screenhouse 2

:iIrpingement. Most fish passing through the Aquaguards were small emerald

shiners and rainbow smelt, whose numbers may have been increased by a

reduction fram previous years in the traveling screen mesh size

fran 0. 375 in to 0. 125 in. It appeared hCMever that the increase in

iIrpingement in 1987 applied to the entire size range of many species.

Increased iIrpingement in 1987 was attributed primarily to increased

numbers of fish in the lake, particularly emerald shiners and ra.inbcM

smelt, within the vicinity of the plant intake.

Collection efficiency, as measured by recovery of marked fish

released into the intake system upstream from the screens, was observed

to be slightly lower in 1987 than in previous studies. The laver

efficiency was attributed to the greater number of small fish in the

samples. These small fish were inefficiently collected by the

Aquaguards .

Survival rates (24-h) of iIrpinged fish were relatively high ()0. 50)

for alltDst all species, especially for the juvenile and adult life

stages; one exception was the alewife (survival rate (0. 05). Generally,

survival appeared to be better during cold months, when impingement was

greatest. Increased screen speed (54 ft/min vs. 18 ft/min) significantly

increased. the survival of juvenile emerald shiners and adult rainbow

smelt in December, but the difference was not significant in the other

montJ?s tested. The relatively good survival denonstrated for Beaudrey

screen suggested that impingement impact at Dunkirk Station could be

mitigated by installing a fish return system, but attention must be paid

to the effects of transport through the entire return system on the

survival of the returned fish. Diversion of fish utilizing behavioral

barriers (e.g. strobe lights, han1ners) may result in greater survival

than that using a fish return system and should not be discarded as a

potential alternative technology without further study.

1 BACKGROUND

The Federal Water Pollution Control Act (FWPCA) Amendrrents of 1972

(PL 92-500) require municipalities and industries clischarging to UnitErl

States surface waters to obtain a National Pollutant Discharge

Elimination System (NPDES) permit fran the authorized federal or state

agency. Niagara Mohawk Power Corporation (NMPC) initially applied for a

NPDES permit for its 628 MW fossil-fpe1ed generating station at Dunkirk,

New York in 1974. An initial draft permit (No. NYOO02321 granted to NMPC

by the U. S . Enviromnenta1 Protection Agency (EPA) J, along with New York

State 401 Water Quality Certification Requirements as administered by the

New York State Department of Environmental Conservation (NYSDEC),

authorized Niagara Mohawk I s Dlmkirk Steam Station (Chautauqua County, New

York) to discharge condenser cooling water (effluent wastes) into Lake

Erie with certain limitations. Under this initial permit, effective on

March 31, 1975, NMPC was required to study the effects of facility

operation on aquatic organisms, including:

a triaxial thermal survey of Dunkirk Harbor and the

receiving waters of Lake Erie (TI 1977a),

a 316 (a) demonstration that addressed the effect of the

heated discharge on Dunkirk fI'.:arbor and near-shore Lake Erie

(TI 1977b), and

a 12-month entrainment and iDpinganent monitoring study

extending from November 1975 through October 1976 (TI

1977c) .

f :

, 

These study results were submitted to reviewing agencies and

accepted in satisfaction of penni t conditions.

Renewal of the discharge permit was required during 1982. Several

additional information requiranents were detailed in the draft and final

State Pollutant Discharge Elimination System ( SPDES) discharge permit

(No. NYOOO232l) for thermal effluent analysis and biological infonration.

The results of t..l1ese studies were suJ:::mitted to the NYSDEC in satisfaction
of the above SPDES permit conditions as follavs:

an analytical thermal analysis evaluating the size of the 10

Of' !:J. T surface isot.l-)enn mAl 1984) , and

a 12-month impingement and entrairunent monitoring study

extending from April 1982 through March 1983 (NAI 1984).

Subsequently, an engineering evaluation was initiated to investigate

alternatives to reduce debris loading on the four unit condensers to

improve station efficiency and reliability. Significant carry-over from

the existing traveling water screens was resulting in condenser tube

plugging problems and reduction in heat transfer. Beaudrey dual-flav

traveling water screens were d'losen to replace t.l-)e existing conventional

traveling screens on Unit No. 4 for a test trial. Beaudrey screens were

installed on unit 4 for engineering testing purposes in th.e spring of

1985. Upon successful caupletion of testing, Beaudrey screens were

retrofitted on the other three units and installation was completed in

the fall of 1986.

On January 6, 1986, a meeting was held by NMPC and NYSDEC to review

the debris loading problem and t.l-)e installation of the Beaudrey screens

at t.he facility. Several conmitments were made by NMPC to address NYSDEC

concerns relative to the viability and impingement of t.1-J.e fish on the new

Beaudrey screens. As a result, a cauprehensive one-year program was

required to evaluate the effect of the upgraded screen system on fish

entrainment, impingement and post-impingement survival (viability). The

cond~ ti9ns of t.'h.is program were outlined by the NYSDEC in an advanced

notification (letter fran Richard Koeppicus to Joseph Miakisz (NMPC),

dated January 28, 1986 J of the biological studies to be included in

NMPC' s modified SPDES permit. Beak Consultants Incorporated (BEAK) was

contracted by NMPC to perform these studies. BEAK, NMPC and NYSDEC met

on Noverober 13, 1986 to review BEAK' s proposal to perform the study. All

parties agreed on a finalized scope of work. The required studies 'for

the program, which carmenced on January 1, 1987, were:

an entrairunent study conducted iran April through August to

determine the species composition and abundance of
ichthyoplankton which enter tile facility cooling water,

0 a one-year sampling program to characterize species

carposition and abundance of fish inpinged on the Beaudrey

screens ,

a one-year study to determine the viability of fish ranoved

fran the Beaudrey screens, and

a one-year study to determine collection efficiency of the

Beaudrey screen and collection (Aquaguard). systems to adjust

irrpingement estimates for fish entering the cooling water

intake but not included in inpingement collections.

The objectives of this program were aimed particula.x1y at evaluating the

effect of the Beaudrey screens on fish abundance, carparing previous

inpingement results obtained fran studies on conventional screens, and at

evaluating the potential benefits of a fish return system. In accordance

wi th the latter evaluation, a separate report was prepared on existing

teclmo1ogy for the reduction of impingement and enhancement of fish

survival through modification of the cooling water intake system and

construction of a fish return system at the Dunkirk Station (BEAK 1987).

The follaving . report sections describe the cooling water system of

Dunkirk Steam Station (Section 1. 2), the Beaudrey screens (Section 1. 3),

and the 1987 Biological Studies (Sections 2 and 3).

1. 2 SITE DESaaPTION

~irk Steam Station, located in western New York State on Lake

Erie, contains four single boiler generator units with a total generating

capacity of 628 HW. The four units collectively utilize 400, 000 gal/mill

(1514 m3/min). Condenser water for the once-through cooling system is

wit.~awn from Lake Erie t.~ough a shoreline intake at the entrance to

Dunkirk Harbor (Figure 1.2-1). Water flaving into the intake system

passes under a skbruner wall which excludes floating debris. This skimner

wall extends approximately 2. 3 m belav the water surface. Water then is

drawn fran the forebay through a pair of trash racks with vertical bars

spaced 7. 6 an apart into two intake pipes. Intake 12, which services

Units 1 and 2, runs 128 m east iran the forebay, then turns 900 and

enters Screenhouse 1. Screenhouse 1 contains three Beaudrey screens

situated approximately 168 m from the intake forebay. Water passes

through the screens before entering the four circulating pumps (rated

40, 000 gal/mill (151. 4 m3/min) each) located near the Unit 1 and 2

condensers. Intake 34, which services the newer units 3 and 4, runs

parallel to Intake 12 for 128 m, then angles slightly and continues for

another 61 m into Screenhouse No. 2. The water passes through four

Beaudrey screens before entering the four circulating punps (rated 60, 000

gal/min (227. 1 m3/min) each). One circulating pump is located

irrmediately behind each Beaudrey screen. Separate intake pipes conduct

water from the pumps to Units 3 and 4.

Condenser discharge water is piped into a carmon discharge flUIre,

which runs for approxirrately 195 m to a shoreline discharge port 

Dunkirk Harbor. Approximately 434, 200 gal/mill (1643. 5 m3/min) of water,

including service water, is discharged under maximum plant operation.

BEAUDREY 'IRAVELJNG 

The Beaudrey traveling screens were installed in the Dunkirk cooling

water system at the same locations as the original conventional traveling

screens. Unlike the conventional screens, the Beaudrey screens are

positioned parallel to water flow, so water passes through both sides of

the revolving screen surface. Flow enters the screens through both the

asc~dil1g and descending sides and exits to the pump inlet through one

end of the screen unit. The side of the screen unit facing the water

flow is sealed. l-Iaximum water approach velocity at the screen face is

estimated to be O. 9 ft/ s at full pumping capacity. The Beaudrey screens

consist of 0. 125-in (3. 2--nm) square mesh, which is finer than the 0. 375-

in ( 9 . 5--nm) mesh on tIle conventional screens. A water spray washes

accumulated debris and aquatic organisms fran the screen surfaces and

into a fish trough. A fish elevator (Aquaguard) system in each

screenhouse removes fish and debris fram the wash water and deposits the

material into trash carts.

The Beaudrey dual-flow screens can be operated in either autanatic
or manual mode. In the automatic mode, screen rotation is governed by

the level of screen differential encountered, and the screens run once

fiNery 2 h for 5 min, provided no abnormal head differential is indicated.

If head differential at the screens reaches 4 in the autanatic screen

wash system runs continuously until levels drop belCM tJle 4 in limit.

Blow-out panels were installed on th.e screen units to protect the screens

during times of extreme debris loading (head differential of greater than

18 in).

In the manual operating mx1e, the screens run continuously until

manually stopped. Prior to August 1987, screens could be manually

operated only at 54 ft/min. Subsequently all screens except Screen No.

32 can be manually operated at either 54 ft/min or 18 ft/min.

2 . 1 ENTRAINl-1ENl'

The objective of the 1987 entrainment monitoring study was to

quantify the ichthyoplankton entrained in Dunkirk Station 

I S COQling water

and passing through the 0. 125-in IOOsh Beaudrey screens. Entrainment

samples were collected weekly from April through August 1987. Four

replicate sanples were collected on each sample date, two during daylight

and two during darkness. All sanples were collected fran Intake 34,

since prior results (TI 1977c) indicated this location was representative

of the entire inta.1ce.

Samples were collected using a 3-in 8-HP gas-J;aYered punp, capable

of pumping approximately 19, 000 gal/h (71. 9 m3/h) at a 30-ft head. Prior

to collection of each sample replicate, the pumping rate was determined

by measuring the amount of time required to pump 1 m3 of water (the

volume of the sample receptacle). The first third of the timed sanple

was collected from the near-surface waters (approximately 2-ft depth).

The sampler was then lCMered to mid-depth, and the final third of the

sample was taken near the bottom. The sampler I s hose was IllOWlted on a

steel pipe to maintain it at the proper depth. The sanple was pl1II'p€d

into a 1-m diameter ichthyoplankton net with 303-micron mesh. The net

was suspended in water to minimize damage to collected organisms.

Sanples were taken upstream of the traveling screens, so a 0. 125-in mesh

net was placed over the ichthyop1ankton net to remove from the 303-micron

rnes~ entrai.nm9nt sanple any large debris and fish that would have been

inpinged.. Retained fish were identified and counted and recorded

separately iran ~1-je processed entrainment sample. The sample duration

e:,IUaled the amount of time necessary to pump 100 m3 of water based on the

pumping rate (m3/s) neasured just prior to the sample. At the end. of the

timed sanple, the net was removed and the pumping rate was rechecked.

Monitoring of the pumping rate prior to and after the sample

collection indicated whether the pmoping rate challged during the sanp1e.

If the difference in time needed to pump 1 m3 of water was greater than

20 percent of the initial punping rate, t.lJ.e sample would be voided and

retaken. Otherwise, the pumped volume was adjusted to equal the mean of
volumes calculated from the initial and final pllltping rates. Water

tarperature was recorded. The net containing the sample was then washed

dcwn, and the contents were placed in a labeled sample jar, to which an

alcohol/propylene glycol/Rose Bengal solution was added.

At the laboratory, samples were strained through a 300-micron sieve

to remove excess stain and preservative. The entire sarnp1e was sorted

with the aid of a dissecting microscope. All ichthyoplankton were

identified to species and life stage, if possible, and counted. Life

stages were categorized as fo11CMS:

Egg : viable egg prior to hatching

Yolk-sac larvae: from the time of hatching to the carplete

absorption of the yolk-sac

fram yolk sac absorption until the full complement

of fin rays and adult body form develop

Post-larvae

Fish were identified to the layest taxon possible. Am:mg the

reference keys used to identify larvae were Auer (1982), Buynak (1979),

Fish (1932), and Mansueti (1964). After processing was carpleted, the

sarnples were retained for quality control processing. Results of the

quality control program are presented in Appendix Table C-84.

Densities of each individual taxon and life stage were calculated

for each replicate sample as number of organisms per 100 m3 of cooling

water. Mean densities fram the two replicate samples collected at the

same date and time period (day or night) were calculated as follCMS:

Di = Dl + D2

where

Di = mean density for sample day i,

Dl 

:::; 

density of replicate 1, and

D2 density of replicate 2.

To observe teIrpOral (weekly) distribution of entrained ichthyoplankton,

average densities per sarnpling date (one sampling day per week) were

calculated by t.l-J.e follC1iling:
where

j 

Did + Din

j - maan density for week j,

Did - mean daytime density for sampling day i, and

Din - mean nighttime density for sampling day i.

Nonth1y estimates of total entrainment by species and life stage

were derived by multiplying the mean daily (weekly) density for each

month by the total monthly intake volume (volume data presented 

Appendix E) .

2 CO~ION EFFICIENCY

The objective of the collection efficiency study was to assess the

perfo:rnance of the Beaudrey screens and the sluice system in r61~ving

fish iran the intake system. Collection efficiency tests were scheduled

to be conducted in February, May, August and Nova11ber 1987. Additional

tests were conducted in Screenhouse 2 on June 15-16 and in Screenhouse 1

on August 24-25 to increase the number of fish tested. The species

tested were the impingement target species (listed in Section 2. 3).

Separate tests were conducted for each screenhouse. Fish impinged during

regular collections and in good condition were used for the collection

efficiency tests. The fish were separated by species, bagged in lots of

100 individuals (if available) and frozen. Just prior to a test, the

fish. w~e thawed and marked with dye and/or a readily apparent fin clip.

For Screenhouse 2 tests, fish were released into the intake tunnel

through a manhole cover approximately 100 m froIl1 the Beaudrey screens.

For Screenhouse 1 tests, fish were released into a separate intake tunnel

through a stoplog channel in the chlorination building approximately

125 m fran the Screenhouse 1 traveling screens. One hundred fish of each

species (if available) were released at each location~ Trash cart-...s in

each screenhouse were monitored for 24 h for IParked fish. The percentage

of returned fish was detennined and irnpingement results for the selected

target species (see Section 3. 2) were adjusted.
2 . 3 IMPlliGEMEm'

The primary objective of the impingement monitoring studies was to

quantify the total ~ingement of organisms on the Beaudrey screens at

the Dunkirk Steam Station. Secondary objectives were to estimate the

biomass of target species impinged, to document the length frequency

distribution of target species impinged, and to compare the 1987

ilTIpingement with results obtained in prior years (1975-1976 and 1982-

1983 ) when conventional traveling screens were in place. The target

species for this study are white perch, white bass, srna1lroouth bass,

yellCM perch, alewife, rai.nbcw smelt, gizzard shad, walleye, northern

pi.'I(e, pickerel and salInonid species. Ilrpingenent sarrpling was conducted

from January 1 through Decanber 31, 1987. The sampling schedule was

stratified by month, with a total of 50 sampling days (Table 2. 3-1).

Sampling was JOC)re intensive during months when iIrpingement was expected

to be greater andl or more variable. Each month was further stratified

into blocks of days (eg. 7-day blocks if four sample days were scheduled

for the month). One sampling day was randomly selected fran each of

these blocks. On a few occasions, sampling could not be conducted on the

scheduled days because of reasons related to plant operations. This

required rescheduling the sampling, but the required sampling was

completed as sexm after the scheduled day as possible and wi thin the

prescribed rronth.

Impingement samples were collected fran the Aquaguard debris removal

system in each screenhouse. A sample was taken by placing two 0 . 125-in

IreSh- n~t liner inside the trash cart receiving fish and debris fran the

Aquaguard. Upon canpletion of a timed sample, the top net liner was

removed from the trash cart, and fish were picked iran the debris, sorted

by species and counted. The second liner was used to keep the fish

collected behleen consecutive samples separate fran others, so game

species that were not impinged during tirred samples could be counted.

Concurrent with the Screenhouse 2 Aquaguard sample, a sample (postAquaguard) was taken fran the water discharged through the Aquaguard

debris elevator into a sampling pit containing a framed net (l-mn IreSh).

This sampling was done to determine the canponent of fish ~ingement

that was not retained by the Aquaguard system. The Aquaguard discharge

was not sa!t'Pled in Screenhouse 1 because of the inaccessibility of the

sampling pit there.

One tilred sample was collected fram each location during each of 12

2-h collection periods over a 24-h sampling day. The sampling day began

at OBOO h for Screenhouse 2 and 0830 hr for Screenhouse 1. 

Sampling time

varied depending on t..1-te number of fish counted during the first 15 min of

each 2-h collection period (Table 2. 3-2). Game species iIrpinged between

timed samples during the sampling day were talleyed and resul ts are

presented in Appendix Table C-B3.

Water temperature and screen operation (number of operating screens

and screen speed) were recorded during each sample. Flow data for the

plant were obtained tram plant personnel and converted to estimates of

cooling water volume pumped (Appendix E). At the end of each collec+-Jon

period, the volume of fish and debris collected was recorded. Fish,

crayfish and other invertebrates were sorted from the debris and the

volume of organisms alone was also recorded.

Additional processing was required for target species. Twenty-five

randanly selec+-..ed individuals of each target species except srnal1n1Outh

bass, yellCM perch, walleye and salInonids were measured to the nearest nm

and weighed. Individual weights were determined to the nearest g for

fish under 500 g and to the nearest 10 g for individuals greater than 500

g. 

Quotas were filled cumulatively for each screenhouse throughout the

sampling day. All srnallmouth bass, yellCM perch, walleye and sa1roonic1s

were individually rreasured and weighed. For each target species, a total

weight of all individuals collected was also determined. After

processing was completed the samples were bagged and stored for quality

control processing. Resul ts of the quality control program are presented

in Apperidix Table C-84.

IrIpinganent was est.iIPated by two methods. The first method involved

an extrapolation of t.~e Irean daily impingement over the entire month. The

mean daily number of impinged fish was calculated as follows:

cp = N x St x 120

where Ncp = estimated number of organisms collection period,

impinged during a

N = number of organisms collected in the sample during

St = number of screens in a particular screenhouse

(three in Screenhouse 1 and four in Screenhouse 2),

Sr = number of screens running during the collection

period, and

t = minutes sampled during a par+...icular collection

period.

Impingement esti.Jrates fran all collection periods were then sUlTlI'ed 

obtain a daily total. daily estimate was calculated for each

nonth by sunming daily impingement totals and dividing by the number of

sample days. The total monthly impingement was calculated by multiplying

the mean daily impingement by the number of days in the month. Total

annual inpingement was the sum of total monthly iIrpingement estimates.

The second met.1-J.od used an impingement rate based on cooling water

volurre, conver+....ed iran hourly flow rates provided by Nl-1PC. Since the 24-h

iIrpingement sampling takes place on two dates ( 0800-0800h) but cooling

water data are on a daily basis, the flCM data were weighted by sanpling

day. The nonth1y total iIrpinganent was estimated as follows:

1 through 4 (OOOO-O800h),

Fl = average flCM (million galjh) on day 1, and

F2 = average flCM (million gal/h) on day 2.

The rrean impingement rate for each mont.1-J. was then calculated by:

Rn-o = ERa
where = mean monthly fulpingement rate, and

n = number of sampling days in month.

Finally t.~e total monthly .impingement was calculated by:

Im = Rn-o x FliO

where TIm = total monthly impingement, and

Im = total volume pumped in the month.

Separate estimates were derived for Screenhouse 2 Aquaguard,

Screenhouse 2 post-Aquaguard, and Screenhouse 1 Aquaguard samples.

Estimates of biomass far target species were derived utilizing similar

formulas .

2 . 4 VIABILITY

The objective of the viability study was to determine the 24-h

survival rates of fish iIrpinged on the Beaudrey screens. Survival of

these fish would make possible their return to the waterbody. Emphasis

was placed on testing the II target species or species groups (listed in

Section 2. 3), but other fish species were tested if conditions permitted.

Test fish were collected by diverting impinged fish from the

tra,:el~ng screens into a fish . collecting device (Figure 2. 4-1).

Collections were made during a 24-h period each month from January

through March and for two 24-h periods during April through December. 

collection was continued for up to 2 h depending on fish abundance 

the amount of debris. Collections were shortened during the light debris

time to unclog the sanpler and minimize damage to the collected fish.

Every effort was made to sample as much of the 24-h as possible. In

April, modifications were made to the oollectors to increase the return

flCM and reduce clogging. These modifications included t.~e installation

of a 6-in diameter pipe at the overflow to channel water back into t.."l-J.e

Aquaguard sluiceway. Upon canpletion of the collection, the fish were

rinsed into baskets within the collection device. After partially

draining the collection baskets, the fish were dipnetted out into

separate buckets according to species, fish size and screen speed tested

(18 vs. 54 ft/min). The fish were then carefully released into the

survival containers directly fran the buckets to minimize handling.

Attenpts were made to test a minimum of 30 fish per species on each

collection day. Fish were held in a flew-through system using lake water

to assure ambient conditions. Tanks were monitored at time of

collection, and 8 h and 24 h after test initiation, for the number of

alive and dead fish as well as for temperature, conductivity and

dissolved oxygen. Dead fish were removed from the tanks and recorded 

The condition of live fish was also recorded. Upon termination of a

test, the tanks were drained and a final count of live and dead fish was

made.

3 . 1 ENTRAIN'-1ENl'

Fish eggs and larvae representing 23 taxa were collected in

entrainment samples in 1987 (Table 3. 1-1). Although fish eggs and larvae

were identified to the lowest taxoncmic group possible, sare specimens

could not be identified to species due to meristic similarities (i.e.

sunf ish, temperate bass, minnows) or damage to key identifying

characteristics. Each of these groups may have contained more than one

species. Emerald shiner, freshwater drum, logperc:.~, trout-perch, rail'lbav

smelt and yellCM perch were the only species collected as eggs. Scme

adult and juvenile eroerald shiners that passed through the 0. 125 in mesh

prescreening net also were collected (Table 3. 1-1).

Over 60 percent of the 17. 6 x 106 eggs entrained were minna.vs,

including emerald shiners (Table 3. 1-2). Logperch (16 percent), rain1:x:w

smelt (11 percent) and yellCM perch (5 percent) contributed most of the

remaining entrained eggs. RainbcM snelt and yellCM perch eggs were

collected only on June 9, during an early surmer storm, whic.1-t created

high waves and brought large amounts of debris or Cladophora into the

plant. Each of these species have demersal, adhesive eggs t.'l-tat may have

been scoured from the lake bottom and brought into the plant attached to

debris and Cladophora These eggs would generally not be a major

canponent of entrair1Irent except during storm events.

Few eggs were collected in April (1. 75/100 m3) and May (0. 19/100 m

entra~t sarnples (Table 3. 3). These relatively few eggs were fran

freshwater drum, smalJmouth bass, trout-perch and logperch. The density

of eggs increased in June with an entrai.nrrent of an estimated 16. 2 x 106

eggs (25. 5 eggs/100 m3). Over 94 eggs/100 m3 were entrained during the

storm event of June 9, contributing over 92 percent of the eggs collected

during this month. Many of these eggs were probably resuspended in the

water column by the wave action and became more susceptible to

entrairunent. l'I.inna.vs (16. 4 eggs/lOO rn3), logperch (4. 3 eggs/100 m3) and

rai11ba.v sm=1t (3. 0 eggs/lOa m3) were the most ccmnonly entrained eggs in

June. In July 407, 020 eggs were entrained, of which 89 percent were

minnCMS . No eggs were collected in August.

OVerall, entrai.nm3nt of eggs in 1987 was less than in 1976 and 1982

(Figure 3.1-1). While an estimated 17. 6 x 106 eggs were entrained in the

present study, 30. 9 x 106 eggs were entrained in 1982 and 172. 0 x 106 in

1976. Egg entrainment during April-May was lower in 1982 and 1987 than

in 1976, when a high density (291.5 eggs/100 m3) of eggs was entrained in

May. Most of these eggs in May 1976 were smelt. In June 1987, egg

entrainment increased iran April-May levels as it had in June of 1982.

In 1987, 25. 5 eggs/100 m3 were entrained in June compared to 24.

eggs/100 m3 in 1982. Miru1ows T,'lere prevalent in June entrainment each

year but smelt eggs, carmon in 1987, were absent in 1982. Very low egg

densities were observed in June 1976. Egg densities were much less in

July and August of 1987 and 1976 than in 1982, due to a large number of

minnCM and unidentified eggs collected during 1982.

An estimated 101. 0 x 106 fish larvae were entrained in 1987 (Table

l-4). Of these, l6. 3 x 106 were yolk-sac larvae and 84. 7 x 106 were

post larvae (Tables 3.1-5 and 6). Rainbow smelt was the dominant

species, contributing 56 percent of the larval entrainment. Other larvae

prevalent in entrainment were yellCM perch ( 27 percent), logperch ( 

percent), minnCMs (4 percent) and ternfei"ate bass (2 percent). Northern

pike, gizzard shad, smallmouth bass, 1arganout.~ bass and walleye were t.l1e

only other target species collected as larvae. Of these, only walleye

contributed greater than 1 percent of the entrained larvae. No sa1monids

or rare or endangered species were collected in 1987 entrainment samples.

In 1987, larval densities were by far highest in June (155.

fish/lOg m3) (Table 3.1-3). The majority (93 percent) were entrained

during the storm event of June 9. Entrainment was reduced in subsequent

rconths. Peak entrainment occurred in June for rainbcM smelt, minnavs,

logperch, yellCM perch and walleyei and in July far teroperate bass and

gizzard shad. Rai,nba,; smelt post larvae was the only species and life

stage entrained in August 1987.

Larval entrainment in 1987 (101 x 106) was reduced from 1982 (18l x

106) and 1976 (411 x 106) (Figure 3. 1-2). The numbers of larval ~IOWS,

gizzard shad and logperch were much reduced tram the previous year, while

the rainbow smelt and yellow perch larvae were entrained in levels

canparable to 1982 (Table 3.1-7). Only walleye larvae showed an

increase, from approxirrate1y 300, 000 in 1976 and 1982 to 1, 200, 000 in

1987. This increase in walleye larvae is reflective of t.'l-J.e resurgence of

walleye in western Lake Erie. Except in June 1987 when densities were

greater than in June 1982, larval entrainment was much laver in 1987 than

in previous years, mainly due to a reduction in entrainment of smelt and

minnows. The high densities in 1976 were mainly attributed to rairJba.l

smelt larvae. Gizzard shad larvae were less prevalent in 1987 then in

the previous studies. A poor 1987 year class of gizzard shad 

suspected, and the low fall irrpingarent of young-of-the-year gizzard shad

in 1987 supports this contention (Section 3. 3).

3. 2 COLI..Erl'lON EFFICIENCY

Collection efficiency data for fish collected at the Aquaguard were

recorded for 14 species, but sample sizes were small for sane species

(Tables 3. 1 and 3.2-2). Sane additional marked test fish had passed

through the Aquaguard and were collected in post-Aquaguard samples,

producing a second set of collection efficiency values (Table 3.

2-3 and

2-4) slightly higher than those for the Aquaguard. Because of

unavailability of sane species during several tests and limited sample

sizes, seasonal estimates could not be made; annual estimates of

collection efficiency (Tables 3. 2-5) were calculated instead, similar to

1982-1983 data analysis.

Collection efficiency tended to be lower in Screenhouse 1 

than in

Screenhouse 2 during 1987 (Table 3. 2-5). When 1987 results were canpared

to 1982-1983 results (NAI 1984) for the same species and screenhouse, the

values were significantly laver in 1987 for ale:.wife (Screenhouse 1:

x2=45. l6, p(O.O!), gizzard shad (Screenhouse 2: X2=4. 28, p(0. 05),

rainbow smelt (SCreenhouse 2: X2=8. 10, tKO. O1), white bass (Screenhouse

1: X2=41. 45, p(O. 01; SCreenhouse 2: X2=9. 48, p'::O. 01), and yellow perch

(SCreenhouse 1: X2=l8. 51, p(O .01; Screenhouse 2: X2=16. 75, p(O . 01) .

Lower collection efficiency during 1987 for sane species may have been

related to the size of fish tested. Since the fish tested were taken

fraIl impingement collections, the size distribution of test fish

reflected the impingenent size distribution for each species. During

1987, small fish (eg. (60 TIm total length) were relatively more abundant

than in 1982-1983 due to the reduction in screen mesh size. The

efficiency of their rezooval by the Aquaguard systan was laver than for

larger fish, as demonstrated by the preponderance of small fish in the

post-Aquaguard samples in 1987. Therefore the lower collection

efficiency values in 1987 may have been the result of the lower

collection efficiency of several small fish included in the 1987 tests.

However, for species such as white bass and yellow perch these

differences could not be attributed to size differences.

For the calculation of collection efficiency adjustment factors to

be applied to inpingement estilvates, a minimum sample size of 25 released

fish was set for each species. Seven target species met this criterion:

alewife, coho salmon, gizzard shad, rainl:x:M smelt, white bass, white

perch, and yell~ perch (Table 3.2-5). These species are hereafter

referred to as the "selected target species " when presenting adjusted

iropingenent rates and totals. Adjustments to the impingement data were

made using t.'l-J.e follCMing formula:

Adjusted value = (inpingement value / (percent recovery/1OD))

These adjustments were made to all impingement rates and total monthly

and annual estimates for both number of fish and bianass.

3 . 3 IMP INGEMENI'

Impingement was estimated by two Jre"L'1ods: 1 an extrapolation of

mean daily impingement across the full year ( 365 days), and 2) 

extrapolation of the nean monthly density using total cooling water

volume (see Section 2, for carputationa1 methods). These two basic

methods were used for estimating both total numbers and total weight.

For the first method, Appendix Tables C-l through C-14 present the mean

daily iropinganent rates by numbers and weight, unadjusted and adjusted

for collection efficiency. Appendix Tables C-15 through C-28 present the

total IOOnthly and annual estimates by numbers and weight, unadjusted and

adjusted for collection efficiency. For the second method, Appendix

Tables C-29 through C-42 present mean monthly densities (number or grams

per million m3), unadjusted and adjusted for collection efficiency.
Appendix Tables C-43 through C-56 present total mnthly and annual

estimates by numbers and weight, unadjusted and adjusted for collection

efficiency .

Adjustments were made for collection efficiency at the Aquaguards at

Screenhouses 1 and 2, but not for the post-Aquaguard collections at

Screen.~ouse 2. Scree.nhouse 1 and 2 Aquaguard estimates furthermore were

canbined to derive total Dunkirk Station estimates comparable to those

produced fran the 1975-1976 and 1982-1983 studies. Neither of these

studies involved sampling of fish passing through the Aquaguard, because

the O. 375-in mesh traveling screens then did not irrpinge as many small

fish that would pass through the Aquaguard as do the O. 125-in mesh

Beaudrey screens in 1987.

Total impingement as recovered frcm the Aquaguard debris removal

systems of Screenhouses 1 and 2 combined was estimated to be

approximately l4. 8 million fish in 1987 based on collection efficiency

(Table 3. 3-1). This estimate was nearly twice that of 1982-1983 (8.

million) and seven tbnes that of 1975-1976 (2. 2 million) (NAI 1984). The

two computational methods (daily rate vs. cooling water volume

extrapolations) differed by less than 2 percent in the estimated totals.

Inpingeroent was approxirnately 40 percent greater in Screenhouse 2 (8.

7 million fish) than in Screenhouse 1 (6. 2-6. 3 million fish). 

additional 8. 0 million fish (not adjusted for collection efficiency) were

estimated to have passed through the Aquaguards in Screenhouse 2 (Table

3-1) . Recirculation of small fish that pass through the Aquaguard

sys!em- and return to the forebay may overestimate the proportional

abundance of the post-Aquaguard CCIr()Onent of Screenhouse 2 impingement.

Almost 90 percent of the fish in the post-Aquaguard collections. were

small emerald shiners and ra.inlx:1.v' smelt (Appendix Tables C-17 and C-45).

These fish would not have been included in 1975-l976 and 1982-1983

collections, and many might have not even been impinged because of larger

screen mesh sizes then (0. 375 in vs. 0. 125 in). If the ratio of postAquaguard to Aquaguard totals in Screenhouse 2 had also held for

Screenhouse 1, the unsampled post-Aquaguard fish in Screenhouse 1 would

have equalled approximately 5 million (unadjusted).

In 1987 there was a 20-fo1d increase in numbers (7. 3 million vs. 0.

million) of emerald shiners over 1982-1983 levels for Aquaguard samples,

as well as a seven-fold increase in rainbow sne1t (4. 3 million vs. 0.

million). It would appear that 1987 impingement totals were elevated

over previous years I impingement by one or more factors. One factor

could be the smaller traveling screen mesh size in 1987, causing more

small fish to be impinged rather than entrained. This possibility is

substantiated by t.l1e relatively large proportion of impinged fish

collected in Screen;.l)ouse 2 post-Aquaguard samples. If the Aquaguard

samples were increased in a similar way by an influx of small fish, it

fu'1ould be reflected in the size distribution of i.Ir--pinged fish such as the

rainbow snelt (Appendix Table C-67). The percentage of small raiIlbaY

smelt ((60 rrm TL) hCMever is 1CM ((4 percent for the year) within the

Aquaguard samples. It appears therefore that the increase in impinganent

of rainbc:M smelt in 1987, as measured in Aquaguard sampling, applied to

the entire size range and could not have been caused by t.'l-te smaller mes:.'1

size alone. Size distribution data are not available for emerald

shiners. These two species may simply have been more abundant in the

lake during 1987 than in previous years. One najor species, the gizzard

shad, was apparently less numerous in 1987 (2. 7 million ilnpinged) than in

1982-1983 (7. 5 million impinged).

The following is a discussion of all species found in the

impingement collections, and in particular, the target fish species.

3 . 3 . Species Canposi tion

A total of 55 fish taxa were identified to the species level during

iIrpingement collections in 1987 (Table 3. 3-2). This was a greater total

than had been collected during the 1975-1976 and 1982-1983 studies (47

species in both). 'lWelve species identified in the 1987 collections but

not found during eit.'ter previous study included brook silverside, burbot,

fathead minnow, johnny darter, longnose dace, mimic shiner, mottled

sculpin, pink sa1Inon, rosyface shiner, sp1ake, tessellated darter, and

white perch. All twelve species have been previously reported for the

Lake Erie drainage basin (Smith 1985) and are not considered threatened

or endangered species. Species not found in 1987 collections but found

in the two previous studies are black bullhead, blacknose dace, bcMfin,

carp x goldfish hybrid, lake chub, orangespotted sunfish, slimy sculpin,

stoneroller, and white crappie. In a recent publication describing t.lJ.e

fishes of New York, Smith (1985) did not have records of either t.~e lake

chub or the orangespotted sunfish as occurring in the Lake Erie basin.

Records of bowfin and black bullhead are scarce in eastern Lake Erie.

Therefore, it would appear that most cann\On Lake Erie species were

encountered in 1987 inpingement collections. Carmon and scientific names

of all fish species collected during 1987 are presented in Appendix A.

Non-fish organisms that were impinged included bullfrogs, crayfish,

rnudpuppies, and tadpoles (Table 3. 3-2) .

The greatest diversity of organisms during 1987 collections occurred

in April (44 taxa) and May (43 taxa), and the least in February, July and

August (18 taxa each). Despite the great diversity, April and Nay were

not the months of highest inpingement; most inpingerrent occurred during

cold months, NoveJrber-lvlarch (Appendix C). In the 1975-1976 study (NAI

1984), May was also the month of greatest diversity of impinged

organisms, unlike the 1982-1983 study (greatest in June and November).

April and May mark the beginning of the breeding season for most

tenperate species, and increasing temperatures and associated fish

n-overrent may cause more taxa to be impinged.

Sane species were inpinged throughout the 12-month period: emerald

shiner, freshwater drum, gizzard shad, rainbow smelt, rock bass,

smallmouth bass, spottail shiner, white bass, white perch, and yellCM

per~h. " Most of these species were iIrpinged year-round in the previous

studies. A notable exception is the white perch, which prior to the 1987

study had not been collected, but now ranks among the most abundant.

Three species (Table 3. 3-3) constituted 96. 5 percent of the total

annual inpingezrent during 1987 by number of individuals: emerald shiner

(49. 3 percent), rainbow smelt (28. 9 percent), and gizzard shad (18.

percent). The same three species accounted for 84. 4 percent of the 1975-

1976 inq)ingement and 97. 8 percent of the 1982-1983 inpingement. Changes

in abundance ranking of these species over the three studies probably

were caused by fluctuating population levels, and to a lesser extent, by

the reduction in traveling screen mesh size when Beaudrey screens were

Of the target species, the rainbc1.Y' sme1 t was dominant by total

weight (61.6 percent) in the 1987 impingement collections (Table 3.3-4).

Emerald shiners were not treated as a target species, and therefore

theirweight was not measured in impingement collections and total

weight was not estimated. Gizzard shad made up 30. 8 percent of tJle

weight of target species impinged in 1987 carrpared , to 86. 7 percent in

1982-1983. No other species contributed greater than 3 percent of the

total ilrpinged weight. The total weight of target species impinged was

less in 1987 (53, 266 kg) then in 1982-1983 (93, 984 kg) due to the

reductin of the number of gizzard shad.

Gizzard shad were especially abundant during the

Impingem:nt during 1987 was heaviest during late fall, winter, and

early-spring (Novanber-April), with peaks in December and March (Figure

1) . The same peaks were observed during the two previous studies.

The December 1987 peak primarily was due to rainbow smelt and emerald

shiners. December \-las the peak month of rainbCM SIre! t iIrpingezrent (

November (alewife, rock bass, and white bass) March (freshwater drum

Target Species Evaluation

Gizzard shad

In t.~e past, gizzard shad has been a daninant species in impingement

collections at Dunkirk Station, ranking first in abundance (86 percent of

total numbers) in 1982-1983 and second in 1975-1976 (Table 3. 3-3). In

...... Gizzard Shad

. 

Rainbow Smelt
1987, gizzard shad ranked only third in abW1dance (18 percent of total

numbers) with an estimated 2. 7 million fish, much less than the 7.

million in 1982-1983.

The reduction in ilnpingenent, particularly during the fall, likely

was the result of a weaker 1987 year class, which was apparent also as

reductions in entrainment during the spring and sumner frcm 1982 levels

(Section 3.1). Fish (150 nm total length (TL), probably YaY, continued

to dominate the August-March collections, but larger fish were corrmon in

November-December and April (Appendix Table C-66). In November-December,

27-60 percent of the gizzard shad were 150-209 nm long and may have been

yearlings. Fish of this size were not ccmnon in November-Decanber 1982

iropingement collections. Gizzard shad larger than 250 nm appeared in

April-May collections. These large fish probably were inshore for

spawning at this time.

Gizzard shad canposed 31 percent (16, 412 kg) of the total impinged

target species bianass during 1987, as c;onpared to 87 percent in 1982-

1983 (Table 3. 3-4). Over one third of the 1987 total biomass of gizzard

shad was iIrpinged during December.

Rainbow smelt

Ra:i.nbav smelt have been dominant in impingement collections since

monitoring began in 1975-1976. SJrelt have ranked second in abundance in

the 1982-1983 and the 1987 studies, and first in 1975-1976 (Table 3. 3-3).

The total number of rainl:xM smelt impinged in 1987 (4. 3 million fish) has

inc~ea~ed greatly over previous levels.

Impinged smelt have ranged frcm approxiInately 20-200 001 total length

(Appendix Table C-67). During July-September the smelt were (70 mn long

and were YOY. Larger smelt first appeared in October collections and

continued to be relatively abW1dant through May. These larger fish would

have been yearlings and adults. Rainbow smelt spawn in early spring, and

the abundance of adults in t.l1e January-March samples probably was related

to onshore movement prior to spawing. The size distribution of impinged

smelt in 1987 did not differ appreciably fran that of previous years.

Rainbow smelt canposed 62 percent (32, 807 kg) of the total invinged

target species biomass during 1987, canpared to 11 percent in 1982-1983
(Table 3.3-4). Total biomass in 1982-1983 was 9, 977 kg and in 1975-1976

was 11, 960 kg. OVer 96 percent of the total weight of smelt was impinged

during November-February (Appendix Table c-S6).

Alewife

A1wi ves have not been a large component of the impingement

collections during the three monitoring studies, carposing 1 percent or

less of the total numbers (Table 3. 3-3). The total weight or biomass has

also been relatively 1CM, estimated at 335 kg during all of 1987 (Table

3 . 3-4) . This total however was greater t11al1 t11e 9 kg reported for

1982-1983 and 231. 1 kg in 1975-1976.

YOY alewife were more carmon in 1987 impingement collections than in

1982-1983. ~1hereas no alewife ..:::50 RID TL were recorded in 1982-1983

collections (NAI 1984), approximately 30 percent of the 1987 collections

consisted of fish of this size (Appendix Table C-65). These YOY were

daninant in July-December collections, and larger fish daninated MarchJune collections.

4 ~~te bass

Population levels of white bass, as indicated by impingement, would

appear to be stable since 1975-1976. The total annual impingement of

white bass has ranged fram 83, 352 to 13l lOl fish over the three Dunkirk

surveys (Table 3.3-3). Total biomass for the two most recent surveys

have ranged fram 1170. 8 kg in 1975-1976 to 1866. 1 kg in 1982-1983.

As in previous years, the vast majority (93 percent) of impinged

white bass were (150 mn TL (Appendix Table C-69). These were primarily

YOY and yearling fish. Larger fish only occasionally were found in

impingement collections, and in 1987 were absent during January-March.

During 1982-1983, white bass )150 ImI TL also were rare during these three

months (NAI 1984).

White perch

Prior to the 1987 study, no white perch had been recorded in

impingement collections at Dunkirk Station (Table 3. 3-3). In 1987

however their total numbers (84, 206 fish) approached that of the
congeneric species, white bass. The total impinged biomass was estimated

to be 1001. 6 kg. The white perch was added to the list of target species

by NYSDEC because of a well-doclnnented increase of the abundance of white

perch recently in Lake Erie.

White perch first invaded Lake Erie in the 1950' S (Boileau 1985),

but did not greatly increase in population size until the mid 1970' s.

Increasingly strong year classes were produced eac:.l1 year tram 1980 to

1984 (Schaeffer and Margraf 1986a). White perch have became abundant in

near-shore and reef areas throughout most of the year. This species has

been studied intensively, particularly in western Lake Erie, wit.'1

attention tCMard possible effects on other valuable species (yellow

perch, walleye, and white bass) caused by competition or predation

(Schaeffer and Margraf 1986a, b~ 1987).

Yellow perch

Yellow perch have increased greatly in impirigernent collections,

possibly indicating a resurgence of this species in eastern Lake Erie.

The 1987 total (42, 583 fish) was approximately ten times that of the

1975-1976 total , and 15 times that of 1982-l983 (Table 3.3-3). Total

bianass in 1987 was 492. 5 kg, compared to 118. 2 kg in 1982-1983 and

225. 10 kg in 1975-1976. The fact. t.l)at bianass has not increased as

greatly as numbers is indicative of a shift in size distribution to

smaller, younger fish. In 1982-1983, 58 percent of the iIrpinged yellCM

perch were -::100 rom TL (NAI 1984), compared to 91 percent in -1987

(Appendix Table C-71). These fish would be YOYand yearlings, indicating

possibly strong 1986-1987 year classes.

Walleye

Similar to yellow perch, the abundance of walleye in 1987

inpingeroent collections has increased dramatically over previous years.

This increase may also reflect. a resurgence of walleye. A total of 187

walleye were estimated to be impinged in 1987, canpared to 23 in 1982-

1983 (NAI 1984). Because the impinged walleye were large canpared to

other species, the estimated total biomass ranked among the top eight

species in 1987 (Table 3.3-4). Most iIrpinged walleye were adults,
exceeding 400 mn TL (Appendix Table C-80).

walleye \Vas a YOY (38 mn TL).

One out of 18 measured

3. 8 Sma1lIrouth bass

Sma11Ioouth bass, like walleye, were not daninant in impingement in

terms of numbers, but ranked relatively highly (11th) by weight aroong

target species (Table 3. 3-4). A total of 702 smallmouth bass were

estimated to be iIrpinged in 1987 (Appendix Table C-49), c::anpared to 1723

in 1982-1983 (NAI 1984). An estimate was not made for 1975-1976, but 92

fish were handled (NAI 1985), suggesting a sanewhat layer total t.."1an

1982-1983 (172 handled).

Impinged srnallmouth bass have ranged fran 37-430 TIm TL in 1987,

suggesting several age groups from YOY to adults were involved.

Impingerrent of this species occurred throughout the year. Large fish

()250 Il1I1 TL) dominated the May and June collections, when spawning would

be expected to occur.

Esocids

Northern pike and muskellunge were rare in impingement collections,

wi th eight northern pike and one muskellunge actually handled.

Extrapolated total estimates were 74 and 12, fish respectively (Appendix

Table C-49). In 1982-1983, 23 northern pike and 68 muskellunge were

estimated to have been impinged. In previous studies these two species

were not treated as target species. Length and weight date for 1987 are

present;;ed in Appendix Tables C-79 and C-81.

3-10 Salmonids

Seven salroonid species were impinged during 1987, including five

from previous studies (bravn trout; chinook sahnon; coho salmon; lake

trout; and splake, a brook trout x lake trout hybrid). Estimates of

total number iIrpinged in 1987 decreased from 1982-1983 levels for chinook

salroon (235 vs. 791), coho salmon (955 vs. 1021), and lake trout (66 vs.

450) . They increased for rainbow trout (349 vs. 31) and remained al.nvst

the same for bravn trout (159 vs. 150). The 1982-1983 totals had shavn

an increase over 1975-1976 levels as the result of increased stocking of
these species over that time period (NAI 1984). As stocking levels have

remained roore constant recently, it would appear that impingement levels

have also remained more constant. Length and weight data presented in

Appendix Tables C-72 through C-77 shCM that the majority of impinged

salmonids are small, recently stocked fish, except for lake trout and

rain1:x:M trout.

3 . 4 VIABILITY

Impingement survival (viability) data were collected for 28

species during l2 months of testing in 1987 (Appendix Tables D-2 through

D- 38) . Table 3. 4-1 presents a S\.IITlI1arY of data for tests run at the

higher screen speed (54 ft/min), canbining months within life stage.

Sample sizes were greatest for the roost abundant species: alewife,

emerald shiner, gizzard shad, rain1:x:M smelt, white bass, white perch, and

yellCM perch. An attempt was made to test 30 fish per species on each

test date, but sufficient fish were available only for the n~st abundant

species on the date. Table 3. 4-2 presents those species for which at

least 30 fish per life stage were tested per month.

Seasonal differences in 24-h survival rates were apparent for

several species and life stages. Generally survival appeared to be

better during cold roonths. For example, survival rates of juvenile

emerald shiners ranged from O. 72-0 . 96 during October-January, but was

42 during September. The highest survival rate of adult white bass

(0. 81) occurred in January, canpared to 0. 51-0. 54 for June-July. Similar

seasonal differences were seen for juvenile gizzard shad and adult

rainbow smelt (Table 3. 4-2).

Survival rates were relatively high ()O . 50) for aJmost all species,

particularly for juvenile and adult life stages. Post larvae and early

juveniles had lower rates, as would be expected. Alewife was an

exception, for WhiCJl tJlere was poor survival ((0. 05) of all life stages

(Table 3. 4-1 and 3. 4-2).

Tests of the effect of traveling screen speed on survival were

conducted during Septe:nber-Decerober. Nine species were tested, but

sample sizes were large only for emerald shiners and rainbcM smelt (Table

4-3). Survival rates for combined months were 0. 83 for emerald

shinersand 0. 39 for rainbow smelt. To test if the rates differed from

those at the faster speed (54 ft/min), the data were grouped by roonth,

life stage, screen speed, and species and subjected to chi-square

analyo:iis.

The survival of juvenile emerald shiners in December was

significantly higher (X2=S. 63, p(O. Ol) at the fast speed than at the

slaver speed (0. 96 vs. 0. 89), but the difference was not significant

(X2=1. 15, p)O. 05) far September data (0. 34 vs. 0. 24 far 54 ft/min and 18

ft/min, respectively). Survival was also significantly higher (X2=12.

p(O. Ol) for adult rainbcM smelt in December at the faster speed (0. 59 vs.

39).

The relatively good survival demonstrated for fish impinged by the

Beaudrey screens suggests that impingement inpact at Dunkirk Station

could be mitigated by installing a fish return system. The survival

demonstrated by these studies hCMever would not necessarily be indicative

of the survival rates of fish returned to the lake. First of all, these

tests were conducted only for a 24-h period, and may not accurately

measure survival beyond. Latent IOOitality can be caused by stress

associated with handling and may not be manifested until well after the

first 24 h. Secondly, additional mortality through handling and stress

can be expected. fran transporting the fish from the debris removal

troughs, where this testing occurred, through the entire fish return

system. This systan could include an underground pipe leading to 

col~ection well and Hydrostal pump, and eventually through a 230Q-ft

(703-rn) long tunnel to the lake. Mortality associated with this handling

and preliminary fish return system designs are discussed in BEAK (1987).

Diversion of fish utilizing behavioral barriers ( e . g . strobe lights

and/or harnners) may result in better survival than that using a fish

return system at Dunkirk and should not be discarded as an alternative

technology without further study. The installation of behavioral

barriers at Dunkirk Station as an alternative to a fish return system is

discussed in BEAK (1987).
