### EVALUATION OF THE DOWNSTREAM MIGRANT BYPASS SYSTEM T . W . 

### SULLIVAN PLANT, WEST LINN Progress Report for 1991-92

PGE T. 

### W. Sullivan Plant is 

## located on the Willamette River at Willamette Falls in West Linn 

### (RM 26.

# 6). PGE has been working on 

### installing, testing and 

### improving a downstream migrant 

## bypass system since 

# 1971. Although significant changes have been made to 

### improve bypass efficiency 

### and to decrease injury 

# (principally descaling) no evaluation tests have been conducted since 

### 1982. From 1983 through 1991 the Sullivan plant was shutdown six to eight weeks each year during the peak of downstream migrations to protect 

### fish. The installation of a new bypass conduit and associated flow 

# control structures and fish 

# trapping andhandling

# facilities (referred to as the evaluator) in 1991 made it possible to resume the evaluation. 

### A formal study plan 

## for" evaluating the T. W. Sullivan Bypass was adopted by the agencies and PGE in November 

# of 1991. Some of the 

### major objectives of the 

### study are to: 1) determine the bypass 

## eff iciency under normal operation 

### (2) determine the source and
extent of injury to fish that use the bypass 

### (3) determine the 

### mortality of injured and non- 

### injured fish within 96 hours after 

### they have passed through the bypass and 

### (4) determine the 

# relati ve abundance and timing of migrants at the Sullivan 

## Plant. The overall performance of the Sullivan system is dependent on two maj or areas 

### , the guidance portion and the 

# bypass. The guidance portion is made up of a training wall and the trashracks in the forebay that act as a louver system to guide the fish through the 

### forebay to unit 

# 13.unit 13 acts as the actual bypass as the entire penstock is screened with an Eicher pressure screen and all of the fish are diverted through a conduit into the evaluator where 

### they can be captured or passed directly to the 

# tailrace. Several changes have been made since the last tests were conducted 

# in 1982. In the guidance portion there were two changes. 

### 1) A 

# set 

# of leaf gates that separated unit 

### 13 from the other units was 

# removed. These gates caused a change in the flow pattern that was 

### believed to increase the loss of

# fish. 2) The trashracks in front 

### of Unit 13 were realigned to a vertical position and they were changed from flat bar on two inch centers to round bar on five inch centers to improve movement into the unit and reduce the chance for 

# injury. In the bypass portion , in the penstock , metal plates were added to make the penstock a more uniform size to reduce turbulence 

### and the entire penstock was 

## cleaned and epoxy appl ied to reduce 

## rough surfaces. Initial tests with the new evaluator were conducted in the fall of 

### 1991 to coincide with hatchery releases of 

# spring chinook. The fish showed up on November 18 in large of numbers (12 

## 000 a day).A single guidance efficiency test was run beginning on November 

### 19.

There was a high flow 

# event (went from 26 

### 000 to 50 

### 000 cfs) on 

### November 21 which flushed most of the fish from the river so no further tests were 

# conducted. Fish were examined for injury and descaling but no control groups were released for 

## comparison. Tests were resumed in March of 1992 to coincide with the release of 

### hatchery chinook. Unusually low flows

## , which persisted through the 

### spring, resulted in extremely high counts of fish , up to 90 000 a 

### day, through the evaluator. Water temperatures reached 70 degrees 

# by

# the first week in 

# June. Guidance efficiency

# tests were attempted on three 

### occasions. One for spring chinook was aborted 

### when we discovered a improperly placed screen in the holding tank 

### allowing fish to 

# escape. A steelhead test was aborted when too 

### many fall chinook showed up and a fall chinook test was run with 

### highly stressed fish (38% overnight mortality in 70 degree water) 

### Some groups of fish were held for 120 hour mortality tests and run 

# of the river fish were classified for injury and 

### descaling. We were unable to complete any injury 

# tests. At the conclusion of the spring migration it became apparent that 

### we would not be able to conduct reliable tests using the 

### same 

# procedures.The main problems

# were: 1) having too many fish to 

# process, increasing the 

### potential of 

### missing marked fish 

### and harming non-test 

# fish;

# 2)thelimited number of 

# fin mark combinations reducing the number of tests that can be conducted at 

### one time; and 3) the extended length of time it takes fish to move 

### through the 

## system. After consulting with agency representatives PGE decided to use a PIT (Passive Integrated Transponder) tag system. The advantages of 

### this system

# are: 1) fish do not have to be anesthetized and 

### handled for interrogation (identification); 

### 2) we will not be limited by large numbers of

# fish; 3) we can run multiple tests at 

## one time;

# 4) our ability to 

### sample will not be affected by 

### extended fish 

### ~assage time

# and 5) we 

# canminimize errors 

# associated with

# fish marking,

# mark identification

# and data 

# transcription. The PIT Tag system was installed 

### the end of 

# October. with the 

### evaluator in the fishing position 100% of the juvenile fish pass through the tag interrogation 

### system. To test the system five fish were tagged and passed through the interrogation tube a total of 87 

# times. Only two tags were missed resulting in a 97. 

### 7 %

# detection 

# rate. Hatchery spring chinook released begining November 9 , 1992 began 

### showing up in numbers at Sullivan on the 

# 16th. We were able to conduct a single guidance efficiency test using the PIT tag system 

### and run of the river fish were examined for injury and descaling. 

### The flow at Salem went form 15 

### 000 on the 15th to 46 

## 000 on the 23rd flushing most of the fish from the 

# river.RESULTS



### Guidance Efficiency Spring Chinook 

### Two guidance 

# efficiency tests were

# completed.Both tests were for hatchery spring chinook at high forebay 

### conditions. One 

# test was with the partial fin mark method, the other was w~th the PIT 

# tag system. In

# both cases groups of fish were released fromthe 

# middle and at either end 

# of theheadracks.

# The fin mark test 

# indicated an average efficiency of 81. 

### 9% while the PIT tag test 

### efficiency averaged 93. 

### 8% (Table 1). 

## There was no significant 

### difference in the guidance efficiencies (X2 =1. 75, P= 

### . 45, wi tp 2 df) 

### between the different release 

## locations. TABLE 1. Sullivan guidance efficiency test for spring chinook. 

### Fin mark test began 11/18/91 with a forebay elevation of 54. The PIT tag test began 11/18/92, forebay elevation 53. C~~-"~.'W",~.~",.,=-,~".~'~'.~~L.~'. -"."-'~'~" =.~"'.."=~,,-,~~~._--_._,,~._,,~,~,~,.~,-,-~-,,~~_.._-_._.=~.~,,._..,~~~-".

# Theaverage size of the chinook used in the 1991 and 1992 tests 

# were 178mm and 195mm respectively. 

## There was

# no difference in the size of fish released and the size of fish 

## recaptured. Steelhead A single guidance efficiency test 

### was attempted for 

## steelhead, wi th 

### low forebay conditions, beginning April 

# 27, 1992. We knew there was only a short window for the test due to the numbers of 

## f ish

# expected. Also due to the large size of the smol 

### ts we were reluctant to hold groups of 

### 200 in each 

### tank. We used wild fish for one of the three 

# groups. The test was aborted after 48 hours 

## when large numbers of fall chinook made it impossible to examin~ 

# all fish. We did continue to capture 

### marked test fish in our 

# normal sampling up 

# to 10 days later. Although this 

# was incomplete test we recaptured 77. 9% of the wild smol ts and 58. of the hatchery smol 

### ts .
Fall Chinook 

### A single low forebay test 

### was conducted beginning 

## June 4. The 

# watertemperature was

## 70 and

# thethree groups averaged 38% 

### prerelease mortality. The fish were released in poor condition. Recapture rates ranged from 43. 7% to 56. 9%.

## calin~ and Injury

We were unable to complete any 

# injury tests due to the 

## large

number of 

# fish in thebypass.However, run of 

# the river fish were examined for injury and descaling (Table

# 2). There were no 

# control

# groups. A comparison of 

# ratings given to 

# the fish between the three 

# diff erentwork crews showed they 

## were very similar, indi~ating the criteria were being applied consistently.

## Dela ed Mortali t 

### Delayed mortality tests were conducted on hatchery spring chinook 

### and hatchery steelhead. Due to limited holding space, tests were 

# limited to

# five
groups of 

### approximately 50 

# fish each. Three

additional tanks are 

### available for 

# 1993. Steelhead classified as 

# descaled had to be collected over several days because they were 

# so few in number and ,

### some were actually held for more than 96 

## hours. Table 3. Ninety six hour mortality for groups of 

## hatchery spring chinook and steelhead captured

### SULLIVAN PLANT

Evaluation of 

### the Downstream Migrant Bypass System Progress Report , Fall 1991

Installation of the evaluator in the flow line of 

## turbine number 13 at the Sullivan Plant was completed by November 1 

### 1991.
During the week of 

### November 11 , 1991 the Oregon Department 

### Fish and wildlife (ODFW) released 800 000 spring chinook smol 

### from their hatcheries above Willamette 

### Falls. The fish averaged 

### 7 to 8 inches in 

## length. Initially our objectives were to; (1) gain operating 

### experience with the new evaluator (2) examine smol 

### ts using the 

### bypass for excessive injury or descaling (3) train personnel in 

### facility operation and fish identification and (4) begin various 

### tests as outlined in the study 

## plan.

When the screen in the penstock of 

### unit # 13 is in the bypass or fishing position the evaluator has 2 different modes 

### operation. One is to directly pass fish (bypass) from the 

### turbine screen to the 

### tailrace. The other mode is to intercept 

### fish from the turbine screen for examination before they enter 

# the tailrace. We began examining fish for descaling and injury on November 

### , 1991. To date we have examined 16 

### 032 hatchery and 752 wild 

### spring chinook 

# smolts. The level of 

### descaling and injury for hatchery fish was 1. 

### 8% and 5. 5% for wild

# fish. How these per

### centages relate to mortalities has not been 

### determined. If 

## they directly relate to mortality then the wild fish percentage is 

## above the 3. 0% mortality level identified in the 1980 agreement 

### between PGE and ODFW. 

### On November 19 

### , 1991 we marked and released hatchery spring
chinook at the beginning of 

# the Sullivan forebay. This test was to determine the percentage of 

### fish entering the forebay which 

### are guided past units # 1 through 12 and enter unit # 13 bypass. 

### The percentage guidance ranged between 77. 4 and 87. 1%. 

### We monitored fish using the bypass system from November 18 

### through December 13, 1991. Most of 

### the fish used the bypass 

### during the first five 

# days. Our last 24 hr. monitoring period 

### (Dec. 12) had only 34 fish (both wild and hatchery)

During the period of 

## November

# 12 through December 13 , 1991 

### the Willamette River flow as measured at Salem ranged between 

### 700 cubic feet per second (cfs) to 72 

### 000 cfs. The 

## Sullivan
Plant has a hydraulic capacity of 

### 000 cfs. with all 13 units 

# operating. All units were operating during this period.

Starting the first part of 

### January we will continue to moni tor 

### the bypass system to determine timing, numbers and species of 

### fish using the system. This is one of 

### the objectives
of 

# our study plan.

Evaluation of the Downstream Migrant Bypass system 

## Progress Report, 

## l\fARCH ,1992 The unit # 13 fish bypass operated the entire month. 

### The bypass was in the fishing or monitoring mode partially or totally 

# for 26 days. The Willamette River flow steadily declined, during 

## the month from 16, 500 cfs to 7, 

### 400 cfs. River water temperatures increased from 49 to 56 degrees F during the month. 

### On March 2 the ODFW began releasing spring chinook from 

# their upriver hatcheries. These fish began using the Sullivan 

### Plant bypass system on March 7, early in the morning before 

### sunrise. The largest fish count occurred on March 10 when an estimated 40, 020 spring chinook smol 

### ts used the bypass 

## system. The counts remained strong through the rest of the month. 

### On March 20 and 25 we conducted delayed (120 hrs. ) mortality 

### tests with fish classified either as descaled or not 

## descaled. 

# The descaled fish had a 8. 2 percent mortality and the not 

### descaled fish 0 

# percent. out of a total of 5, 

### 404 wild and 

### 193,

## 625 hatchery spring chinook 3. 3 percent, for both groups, 

### were classified as descaled or 

# injured. This percentage (3. 3 %) 

### is not corrected for the condition of fish entering the Sullivan Plant forebay. 

### Because of the unseasonably low flows in the river and 

### corresponding low forebay elevations unit #9 was shut down and 

### generation at the plant was reduced to maintain adequate flow through the bypass. 

### During the month personnel from the Department of Fish and 

## Wildlife , Oregon state University, were examining hatchery spring 

### chinook as part of a fish migration

### Progress Report, ~ay, 1992 

# The unit # 13 fish bypass operated the entire month. The bypass was in the fishing or monitoring mode partially or totally 

# for 24 days. The Willamette River flows declined during the 

## month from 17,

## 200 to 6, 200 cfs. River water temperatures 

### increased from 57 to 69 degrees

# F. Because of the low flows at 

### the end of the month it was necessary to either reduce load on all the units or to take one or more units off line in order to 

### maintain the necessary flow through the bypass 

## system. On May 14 we held 2 groups of hatchery steelhead for a 96 

### hour delayed mortality test. One group (49 fish) was classified 

### as descaled and the other group (52 fish) was classified as OK. 

### The descaled group had a 2% mortality and the OK group 0%. 

### On May 27'

## we examined 5, 582 fall chinook, 96 coho and 189 

### hatchery steelhead for descaling and injury rates. Those descaling and injury rates were 2. 

### 5% for fall chinook, 3% for 

### coho and 8% for hatchery steelhead. As mentioned in previous 

### monthly reports these ~escaling 

# andinjury rates are not adjusted 

### for the condition of these fish before they enter the bypass 

## system. Because of the large numbers of fish using the bypass system we were unable to conduct any tests to determine bypass 

### efficiency, descaling or injury, and calibration.

## NOVEMBER, 1992 On November 9 the ODFW began releasing spring chinook smolts 

### from their upper Willamette River hatcheries 

### (Table 1). 

## As the fish moved downstream through the Sullivan Plant bypass system we 

### were able to conduct one forebay guidance test , using the new PIT 

### tag equipment 

### , and examine fish for descaling and 

# inj ury. The forebay guidance efficiency was 93. 

## 8% (616-released; 578- 

### recaptured). The fish were released on November 18 and the test 

### was terminated on November 

# 24. During this period the penstock 

### screen was back flushed for cleaning 11 

# times. From November 16 

### through the 28 we examined 13 

### 616 hatchery and 192 wild spring 

### chinook for descaling and injury after they had passed through 

### the bypass 

### system. We did not examine any fish prior to entering 

### the bypass 

# system. The descaling and injury rate for hatchery spring chinook was 4. 

### 7% and 0. 5% wild spring chinook. 

### The Willamette River flows, as measured at Salem , increased from a low of 11, 

### 300 cfs on November 7 to a high of 46 000 cfs on 

### November 23. Water temperatures at the Falls dropped during the 

### month from 56 to 45 degrees F. (ODFW 

### data) . For the last two years high river flows and increased debris load in November has required frequent back flushing or cleaning 

### of the penstock 

### screen. As a result the penstock screen is not 

### always in the fishing position during these high debris load 

## periods. Based on the timing of fish through the Sullivan bypass the 

### shutdown of Simpson and Smurfit hydro units (November 13 through 

### 27) occurred when the greatest number of fish were passing the Fa 11s.
