# 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 m 

# 3/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

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 m 

# 3/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 m 

# 3 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 m 3 of water based on the



# pumping rate (m 

# 3/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 m 3 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 m 3 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

# 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

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 N cp = estimated number of organisms

# N = number of organisms collected in the sample during

a particular collection period,



# 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

annual inpingement was the sum of total monthly 

# iIrpingement estimates.



# The second met.1-J.od 

# used an impingement rate based on cooling water

# 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

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

# 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 m 

# 3) 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 m 

# 3).

Over 94 eggs/100 m 3 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 rn 3), logperch (4. 

# 3 eggs/100 m 3) and



# rai11ba.v sm=1t (3. 0 eggs/lOa m 

# 3) 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.

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 m 

# 3) (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

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 m 3), 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.

as well as a

# factor

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

# substantiated by t.l1e relatively large proportion of impinged fish



# collected in Screen;.l)ouse 2 post-

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

# (Appendix Table C-67). The percentage of small 

# raiIlbaY



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

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

# in the Lake Erie basin.

Records of bowfin and black bullhead

Therefore, it would appear that most cann\On Lake

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.

# 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 ilnpingenent, particularly

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



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

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

# iropingement collections. 

# Gizzard shad larger than 250 nm appeared in

# percent in 1982-



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

shad was iIrpinged during December.

# 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

(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

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

white bass has ranged fram 83, 352 to 13l

# 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

impingement collections, and in 

# 1987 were absent during

During 1982-1983, white bass )150

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.

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

# 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.

# 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
