The Corps of Engineers' fish transportation program used the 

Bradford Island fish release facility and the Hamilton Island boat 

launch area to release truck hauled fish transported from 

collection facilities at McNary, Little Goose and Lower Granite 

dams. Flow conditions appear to be better at the boat launch area 

for fish release when the tailwater drops to a low range. 

The Corps of Engineers' Portland District Fisheries Field unit 

conducted a fishway operation evaluation. The work was done to 

3 
identify problem areas related to fish passage and recommend longterm solutions. 

The Columbia River Inter-Tribal Fish Commission used the second 

powerhouse Adult Fish Collection and Monitoring Facility to collect 

salmonids. The work was done to satisfy a requirement of the 

u.s. - Canada Pacific Salmon Treaty to identify "indicator stocks". 

These stocks will be monitored annually to evaluate the success of 

a program designed to rebuild depressed Columbia River salmon 

populations. Fish trapped were returned immediately to the fish 

ladder and there was no impact to the official fish count. 

The Fish Passage Center continued to coordinate a fishway 

inspection program which involved once per month fishway 

inspections by a National Marine Fisheries Service inspector at 

Bonneville. 

The National Marine Fisheries Service continued to use the Adult 

Fish Collection and Monitoring Facility at the second powerhouse to 

capture marked fish as part of an evaluation of juvenile salmonid 

transportation. Primary efforts involved observing branded, codedwire tagged spring chinook salmon from COE-funded studies at McNary 

Dam and similarly marked sockeye salmon from a BPA-funded study at 

Lake Cle Elum. All fish were returned to the ladder after 

examination and were counted at the counting station as usual. 

The National Marine Fisheries Service used the juvenile bypass 

system fish sampling facilities at both powerhouses to monitor 

passage of downstream migrants. The monitoring period was 15 March 

through 30 November. 

The National Marine Fisheries Service continued to investigate the 

juvenile fish bypass release conduit at the second powerhouse. The 

work emphasized isolating areas within the conduit which appeared 

to be associated with fish injury and evaluating the system during 

low tailwater. A structure was attached to the outlet in November 

of 1990 to enable placing the mouth of a net over the JBS outlet 

for direct recovery of fish during studies. 

The National Marine Fisheries Service conducted Fish Guiding 

Efficiency studies at the first powerhouse to determine how well 

the turbine intake screens divert fish into the bypass system. The 

work included investigation of vertical distribution of fish within 

selected turbine intakes and potential to improve FGE by raising· 

"operating" gates. Raising these gates increases 

velocity of water in the adjacent slots where the submersible 

traveling screen directs fish to the bypass system.

The following agencies participated at Bonneville Dam in the 

squawfish management and research program. 

• The Oregon Department of Fish & Wildlife coordinated much of 

the BPA funded squawfish management and research program, 

including the work described here for other agencies' 

squawfish work. They participated directly in sampling 

squawfish populations by boats and in sampling the catch of 

the CRITFC dam anglers. 

• The Columbia River Intertribal Fish Commission removed 

squawfish by angling from various locations on the dam. 

Squawfish are predators on juvenile salmonids and are believed 

to cause significant impact, particularly at locations such as 

the first powerhouse forebay, because prey and predators 

collect in large numbers. Fish collected were removed from 

the project by Oregon state University. 

• The National Marine Fisheries Service participated in the 

squawfish program in harvest technique development. They 

investigated the usefulness of the following techniques. 

o Seining in the tailrace and forebay of the first 

powerhouse. 

o continuous long-line fishing in the first powerhouse 

forebay with multiple lures. 

o Electro-fishing with fixed and portable electrodes off the 

first powerhouse forebay deck. 

• The US Fish & Wildlife Service, with assistance from the 

Oregon Department of Fish & Wildlife, investigated predator 

abundance and consumption rates through much of the Columbia 

River system. The work at Bonneville involved electroshocking and gill netting from boats in much of the area near 

the dam. The information will be used to help direct predator 

control management in the future. 

The U.S. Fish & Wildlife Service used the Adult Fish Collection and 

Monitoring Facility to collect early spawning (tule) fall chinook 

to supplement returns of adults to Spring Creek National Fish 

Hatchery. A total of 709 chinook (255 males and 454 females) were 

trapped between 2 and 4 September, and were transported to the 

hatchery. These fish were not counted at the dam and counts were 

not adjusted for them. 

The USFWS conducted a study involving 4 releases of fish ending on 

5 September, designed to provide information about the preference 

of squawfish for dead or live juvenile salmonids. Releases were 

made from the Bradford Island juvenile fish release facility and 

squawfish were collected by electro-shocking overnight. The tests 

required shut down of units 9 & 10. 

5 
The US Fish & Wildlife Service collected a few hundred salmonid 

smolts as part of a study of factors influencing seaward migration 

of fall chinook salmon through the river system. 

The Washington Department of Fisheries and Oregon Department of 

Fish & wildlife cooperated in conducting special fish counting 

again this year to update upriver fall chinook run size estimates. 

This work has continued since 1979. 

The Washington Department of wildlife counted adult fish under 

contract with the u.s. Army Corps of Engineers. Fish were counted 

according to the schedule above for 50 minutes of each hour. The 

50 minute totals were multiplied by a factor of 1.2 to estimate 

passage for each full hour. 

The Washington Department of wildlife conducted special counting 

during the winter of 90/91. Fish passage was video recorded 

between 1 December and 14 March, 24 hours per day, and the record 

was subsequently viewed to count fish. The focus of this work is 

on steelhead passage and is not yet complete. 

Guiding efficiency of th~ juvenile bypass system of the second 

powerhouse was still considered unsatisfactory. So, operation of 

the second powerhouse was restricted again this year. During the 

middle 80 percent of the spring and summer juvenile salmonid 

migration period, the powerhouse did not operate except to limit 

spill to 75,000 cfs during daytime or for fishery research. ~ •. 

limit on daytime spill is to prevent adult fish from falling back 

from the forebay through the spillway. Adult fish passage is much 

reduced at night.

The Corps of Engineers' Portland District Fisheries Field unit 

conducted a fishway operation evaluation. The work was done to 

identify problem areas related to fish passage and recommend longterm solutions. 

The Fish Passage Center continued to coordinate a fishway 

inspection program which involved once per month fishway 

inspections by an Oregon Department of Fish & wildlife inspector at 

The Dalles Dam. 

The National Marine Fisheries Service monitored smolt passage by 

sampling fish from a gate well at turbine unit 2. Sampling was 

done by use of an airlift sampling device. This activity continued 

from 2 April through 31 August, 24 hours per day. 

Construction was completed on a small hydroelectric facility which 

now uses the north fish ladder auxiliary water supply to generate 

power. This project is owned by Northern Wasco County People's 

utility District and includes a juvenile fish bypass system. The 

unit began continuous operation on 28 May. 

The following agencies participated at The Dalles Dam in the 

squawfish management and research program. 

• The Oregon Department of Fish & Wildlife coordinated much of 

the BPA funded squawfish management and research program, 

including the work described here for other agencies' 

squawfish work. They participated directly in sampling 

squawfish populations by boats and in sampling the catch of 

the CRITFC dam anglers. 

• The Columbia River Intertribal Fish Commission removed 

squawfish by angling from various locations on the dam. 

Squawfish are predators on juvenile salmonids and are believed 

to cause significant impact, particularly at certain locations 

where prey and predators collect in large ~umbers. Fish 

collected were removed from the project by Oregon State 

University. 

8 
• The University of Washington operated Merwin traps in the culde-sac area beside the East fish ladder to trap squawfish. 

They also tried purse seining to evaluate its use as a 

squawfish collection technique. They also set baited longlines 

in the cul-de-sac to compare catch with that from the traps. 

The USDA Animal Damage control unit continued the task of 

controlling predation of gulls on juvenile salmonids. They 

improved the installation of gull inhibiting lines across the river 

near the outfall of the ice and trash sluiceway. They also used 

noise makers and pyrotechnics. 

The Oregon Department of Fish and wildlife conducted sturgeon 

research, using setlines in the tailrace at various times between 

April and August. -

The Washington Department of wildlife counted adult fish under 

contract with the U.S. Army Corps of Engineers. Fish were counted 

according to the schedule above for 50 minutes of each hour. The 

50 minute totals were multiplied by a factor of 1.2 to estimate 

passage for each full hour. 

The Dalles Dam was involved in the agreement to provide spill for 

improved juvenile fish passage again this year. The agreement 

provides spill for this purpose between 1 May and 22 August.

April and August. 

The US Fish & wildlife Service collected a few hundred salmonid 

smolts as part of a study of factors influencing seaward migration 

of fall chinook salmon through the river system. 

The Washington Department of wildlife conducted the 1990 fish

Fish were counted according to the schedule above for 50 minutes of 

each hour. The 50 minute totals were multiplied by a factor of 1.2 

to estimate passage for each full hour. 

John Day Dam was involved in the agreement to provide spill for 

improved juvenile fish passage, again this year. Survival is 

better for fish passing through spill than through turbines. The 

agreement calls for spill to be provided for this purpose in the 

summer between 7 June and 22 August. 

Concern continued regarding salmonids accumulating in the upper 

parts of both ladders and leaping, sometimes out of the ladder. 

Netting was installed over part of the north ladder flow control 

section in a fashion similar to that done earlier over the south 

ladder.

counted by direct observation. Fish counting from 1 April through 

31 October in 1991 was accomplished under contract by the state of 

Washington Department of wildlife. Fish counting from 1 November 

through 15 December was accomplished by the state of Washington 

Department of Fisheries as part of an adult fallback study. 

The Columbia River Inter-Tribal Fish Commission removed squawfish 

by angling from various locations on the dam. Squawfish are 

predators on juvenile salmonids and are believed to cause 

significant impact, particularly at certain locations where prey 

and predators collect in large numbers. Fish collected were 

removed from the project by Oregon state University. 

Washington Department of Fisheries evaluated adult salmon and 

steelhead fallback through the juvenile bypass system from 

15 September through 15 December. 

The juvenile collection system was in operation from 25 March 

through 15 December. 

National Marine Fisheries Service conducted fish guiding efficiency 

research using extended length screening devices in turbine units 

five and six.

TABLE 2 

STEELHEAD OVER COLUMBIA AND SNAKE RIVER DAMS 1953-1991 

BY RUN-YEAR (1 JUNE - 31 MAY) 

Estimating the size of the upriver steel head run has previously been hampered because of the calendar year 

approach used in the summary tables. Problems in accountability arise due to overwintering behavior of summer 

steelhead; especially Snake River stocks, which often have sizeable proportions of the run remaining below mainstream 

projects during the winter months. Movement of these steelhead trout commences again the following spring when 

warming reservoir temperatures trigger upstream movement. For this reason, an additional table has been prepared 

which summarizes steelhead counts at each Project on a "fish year" basis; 1 Jun - 31 May. Because all stocks 

of Steel head cross Bonneville Dam during the calendar year, those summary counts have not been modified.

+Because counting started at each dam early in the year after construction was complete, 

these figures are for the latter part of the run year only. That part of the run-year starting after 

June 1 st of the previous year passed the dams without being counted. 
STEELIlEAD KELT COUNT 

at 

PORTLAND and WALLA WALLA DISTRICT PROJECTS 

The majority of steelhead migrating up the Columbia River past Corps of Engineers dams 

are summer-run steelhead. Most of these fish enter freshwater between March and October 

and migrate upstream toward their place of origin. During the spawning run, a steelhead's 

feeding is greatly diminished and it must rely on stored fat reserves for sustenance while in 

freshwater. Since most of these fish are spring spawners (March - June), their original body 

weight is reduced by up to 40% after spawning. After a steel head has completed spawning, 

it is called a "kelt". If a steel head kelt can successfully reach the ocean and survive, it may 

return to freshwater to spawn again. 

Washington Department of Wildlife fish-counting staff have observed a downstream 

movement of kelts at Corps of Engineers projects. Peak downstream migration of kelts 

occurs in May and they are most often sighted at McNary and John Day Dams. These fish 

are emaciated, gaunt, and weak. The torpedo-shape, characteristic of a steel head fresh from 

the ocean, has deteriorated into a snake-like shlilpe with a large head. Most kelts appear to 

be females. They are oriented 'into the current but allow the current to carry them 

downstream past the counting window. After a meeting with the Corps of Engineers, 

fisheries agencies, and tribal biologists in 1989, it was agreed that the Washington 

Department of Wildlife fish-counting staff would count kelts. The downstream movement 

of steel head kelts is presented on the following page in Table 2-A.

MISCELLANEOUS SPECIES SIGHTED at BONNEVILLE, 

THE DALLES, and JOHN DAY PROJECTS 

1991 

Fish counters at Portland District Projects recorded the presence of species other than 

Salmon, Steelhead, and Shad. The squawfish counts are adjusted; that is the 50 

minute totals are multiplied by 1.2 to estimate passage for a full hour. Squawfish 

passage peaked during May, June, and July. Squawfish were most abundant in The 

Dalles east ladder. 

The sturgeon counts are net upstream movement. In past years they have been 

reported only as sightings. These counts are not ad.justed. Sturgeon passage peaked 

in July, August, and September. The counts were highest in The Dalles east ladder. 

Sizes ranged from 1 to 11 feet. 

Smallmouth bass and walleye counts are net upstream counts and are unadjusted. 

Bass counts peaked at Bonneville in the fall while at the Dalles and John Day there 

appears to be a spring and fall peak. The most bass were observed in the John Day 

south ladder. Walleye counts peaked in September at John Day Dam and remained 

steady through out the season at The Dalles Dam. No walleye were observed at 

Bonneville. The majority of walleye were observed in The Dalles east ladder .
