ABSTRACT

Important runs of salmon and steelhead trout pass Rock Island Dam on the

Columbia River.

Count of 33,067 Chinook salmon in 1961 was well above the mean of 15,560 for the

28-year period 1933-60 and exceeded the 1960 count of 26,532. Sockeye salmon count

of 19,233 was slightly more than one-third the 28-year mean of 53,079. Only 50 coho

salmon were recorded in 1961. Greatest number of coho salmon, 229, occurred in

1947. The 7,042 steelhead trout passing Rock Island Dam in 1961 was the highest

count recorded since counting began in 1933 and was more than twice the 28-year

mean of 3,063. 140,173 fish other than salmon and steelhead trout passed through

the fishways at Rock Island Dam in 1961.

INTRODUCTION

Rock Island Dam, located on the ColumbiaRiver approximately 12 miles downstreamfrom the city of Wenatchee, Wash., has been

in operation since 1933. The plant is ownedand operated by Chelan County Public Utility

District No. 1.

This report on passage of fish at Rock Island

Dam during 1961 provides information on

operation of fishways and numbers of fish

utilizing upstream fish passage facilities.

Rock Island Dam is now equipped with three

fishways: one located on the right bank.

another on the left bank, and the third ap-

proximately in the center of the dam. Two of

the fish ladders were placed in operation in

1933, and the third (middle ladder) was con-

structed in 1935-36. All three ladders have

undergone significant modifications sinceinitial construction.

Included in this report are comments cover-

ing various investigations carried on at RockIsland Dam during 1961.

COUNTING PROCEDURES

Fish counting in 1961 began on May 1 and

terminated on October 27. From May 1 to

August 19, counting was conducted 16 hours

each day, starting at 5 a.m. and ending at

9 p.m. From August 20 to September 30, to

conform to hours of daylight available, count-

ing was reduced to 14 hours each day, start-

ing at 5 a.m. and ending at 7 p.m. FromOctober 1 to October 9, counting was further

reduced to 8 hours each day, starting at 8 a.m.

and ending at 4 p.m. From October 10 to Octo-

ber 27, counting was conducted from 8 a.m. to

5 p.m., with 1 hour closure of gates at noon.

A 15-minute rest period was allowed at the

end of each hour, and during all periods of

noncounting, ladders were closed to passage

of fish.

ENUMERATION OF FISH

Chinook Salmon,Oncorhynchus tshawytscha

The Chinook salmon count in 1961 of 33,067

(jacks included) was well above the mean of

15,560 for the 28-year period 1933-61. Thecount increased over the 1960 run and was a

little more than half the peak annual count of

50,713 in 1957 (table 1). Monthly totals of

Chinook salmon counted are given in table 2.

Maximum day's count of Chinook salmon, jacks

not included, in 1961 was 692 on August 7

(table 3). Tables 4 and 5 show semimonthly

totals of number and percentage of Chinook

salmon count which ascended each fish

ladder.

Chinook Salnnon Jacks

Some Chinook salmon return from the ocean

during the year following their seaward migra-

tion and are referred to as "jacks." Thesefish are predominantly males and are smaller

than the average. It has been determined at

Rock Island Dam that up to June 30 of each

year, jacks rarely, if ever, exceed 18 inches

in length, while the balance of the fish ap-

preciably exceed that length. Likewise, fromJuly 1 to the end of the season, jacks rarely,

if ever, exceed 22 inches in length. Conse-quently, jacks at Rock Island Dam are identi-

fied by considering all Chinook salmon 1 8 inches

or less in length prior to July 1 as jacks, andall Chinook salmon 22 inches or less in length

subsequent to June 30as jacks. Maximum day's

count of Chinook salmon jacks was 199 and

occurred on September 18 (table 3). The 9,260

fish recorded as jacks constitute 28.0 percent

of the 1961 Chinook salmon run.

Table 5 shows number and percent of chinook

salmon jack count which ascended each fish

ladder. Monthly totals are given in table 2.

Sockeye Salmon, Oncorhynchus nerka

(blueback or red)

The sockeye salmon count of 19,233 for 1961

was less than half the 28-year mean of 53,079

(table 1). In 1961 peak of the run was reached

on July 14, when 1,289 fish were counted

through the fishways at Rock Island Dam.

In recent years attention has been drawn to

the many small sockeye salmon appearing at

Rock Island Dam. During the 1961 counting

period at Rock Island Dam sockeye salmonunder 16 inches in length were enumerated as

small fish. Number of sockeye salmon re-

corded as "small" was 3,497 (6.6 percent).

Tables 6 and 7 show semimonthly totals of

number and percentage of sockeye salmoncount ascending each ladder. Of the sockeye

salmon passing Rock Island Dam in 1961,

65.6 percent ascended the left ladder, while

9.9 and 24.5 percent ascended the middle and

right ladders, respectively. Data pertaining to

sockeye salmon daily counts are contained in

tables 9-14. Monthly totals of sockeye salmoncounted in 1961 are given in table 2.

Coho Salmon, Oncorhynchus kisutch

(silver)

The coho salmon count of 50 fish in 1961 wasslightly less than the 28-year mean of 61, and

sligthly more than half the 1960 count (table 1).

Additional data are shown in tables 11 and 12.

Maximum day's count of 8 fish occured on

October 4 (table 2).

Steelhead TTO\iX,Salmo gairdneri gairdneri

The steelhead trout count of 7,042 in 1961

was well above the 28-year mean of 3,063

(table 1).

Additional data pertaining to steelhead trout

daily counts are contained in tables 7-12.

Maximum day's count in 1961 was 269 on

September 19 (table 2),

WEATHER AND RIVER DISCHARGEDATA

Table 6 shows semimonthly totals of numberand percentage of steelhead trout which as-

cented each fish ladder.

Miscellaneous Fish

In 1961, enumeration was made of species of

fish other than salmon and steelhead trout

passing Rock Island Dam, Data pertaining to

these fish are given in tables 15-20. No claimsare made as to complete accuracy of identifi-

cation of these fish. It is felt, however, that

the degree of accuracy is consistent with that

maintained at other dams on the Columbia Riverand as such may be used as a rough index of

abundance of these fish. In 1961, approximately140,280 fish other than salmon and steelhead

trout passed Rock Island Dam.

Headyvater and tailwater elevations areplotted on figures 1 and 2, respectively. From1 p.m. on June 9 through June 13 all fish facili-

ties were nonfunctional due to high water. Air

temperatures were taken twice daily by pocket

thermometer. Water temperatures were taken

at center fish ladder by recording thermometer.Daily records of weather conditions and streamflows are shown on tables 9-14. Daily river

discharge data are plotted on figure 3,

ACTIVITIES AND OBSERVATIONS

A count of 137 Chinook salmon on May 1

indicates that initial movement of these fish

probably began prior to that date. This is in

striking contrast to the late start of fish on

May 18, 1959.

As in past years of counting at Rock Island

Dam, some fish were observed with cuts or

abrasions on the body. Of 40, 764 fish examined

as they passed over the counting boards, ap-

proximately 1.06 percent had injuries of sometype either on the body or about the head. Since

the counters could see only the top and one side

of the fish, the incidenceof injury was probably

greater than indicated. In period May 1 to July

5 all fish were quite free of injuries. Greatest

numbers of injuries were observed during July

and August and were most numerous on large

Chinook and sockeye salmon (table 21). In period

July 20 to August 12 counters reported a numberof fish with similar injuries. The injury mostcommonly observed was a circular cut or

abrasion about 1 inch in diameter, usually along

the side of the fish. Some of these injuries

were newly made as evidenced by the presence

of bloody tissue. Others appeared to have been

made much earlier as scar tissue wasforming.

During extreme highwater period June 10-13

a considerable quantity of gravel, silt, and

debris was deposited in the right bank fish

ladder.

On July 19 counting facilities at left fish

ladder were operated from 9:30 p.m. to 11:45

p.m. Between 9:30 p.m. and 9:45 p.m. two

Chinook and two sockeye salmon passed over

the counting board. From 9:45 p.m. to 11:45

p.m. there was no movement of fish ob-

served.

The six times that dewatering of fishways at

Rock Island Dam occurred in 1961 were as

follows:

1. Left fish ladder, from 10 p.m. on May 3

to 1 p.m. on May 5, to install electronic count-

ing equipment.

2. Right fish ladder, from 10 a.m. to 3p.m.on June 5, to clean ladder orifices and repair

telescopic gate chains,

3. Right fish ladder, from 12:45 p.m. to

2:40 p.m. on June 7, to complete ladder re-

pairs.

4. All three fish ladders, from 1 p.m. on

June 9 to start of counting on June 14, wereinoperative due to high water.

5. Right fish ladder, from 11 a.m. to 3:15

p.m. on June 29, to replace stoplogs lost during

high water period.

6. Right fish ladder, from 12:50 p.m. to

2:40 p.m. on July 5, to repair broken gate

chain.

SUMMARY

1

.

The total Rock Island Dam count of salmonand steelhead in 1961 was 59,392, which wasslightly more than half the 1960 count of

93,183.

2. Yearly total counts of salmon and steel-

head passing Rock Island Dam during theperiod

1933-61, inclusive, are given in table 1.

3. The Chinook salmon count of 33,067 in

1961 was greater than in 1960 and slightly morethan half the peak year of 1957. In 1961, 9,260

jacks were recorded, representing 28.0 percent

of that year's total Chinook salmon counted.

4. The sockeye count of 19,233 was slightly

less than one-third the 1960 count of 60,341

and considerably less than the 28-year meanof 53,079. A greater percentage of sockeye

salmon utilized the left bank ladder than used

either the middle or right bank ladders. In

1961, sockeye salmon under 16 inches in length

comprised 18.2 percent of the count.

5. Very few coho salmon have appeared at

Rock Island Dam in the period 1933-61. Thegreatest count, 229, occurred in 1947. The1961 count of 50 fish was slightly more than

half the 1960 count.

6. The steelhead count of 7,042 in 1961 ex-

ceeded the 28-year mean of 3,063 and was the

highest recorded in the period 1933-61.

7. Fish counting in 1961 began on May 1

and terminated October 27. From May 1 to

August 19 counting was conducted for 16

hours each day; from August 20 to September30, 14 hours each day; and from October 1 to

October 27, 8 hours each day.

8. In 1961 the maximumnumber of salmonids

counted in one day (1,651) was on July 14.

9. Season's total of fish other than salmonand steelhead trout passing Rock Island Damin 1961 was 140,173, and was composed of the

following: sucker, 76,797; squawfish, 15,174;whitefish, 23,124; chub, 6,754; and "other fish,"

composed largely of lamprey and carp, 18,324.

10. Of 40,764 fish examined, on the top andone side only, as they passed over the counting

boards, approximately 1.06 percent had in-

juries of some type either on the body or about

the head. Greatest numbers of injured fish oc-curred in July and August. Injuries were mostnumerous on large chinook and sockeye salm-on.

11. High water conditions at Rock Island

Dam made the fish ladders inoperative fromJune 9 to 13, inclusive.
