4. Non-salmonid species moved in maximum abundance on 10 July when 

27,744 shad and 1,456 miscellaneous other fish were recorded. 

5. A large run of 557,513 shad passed into the Bonneville forebay. 

Of these 399,028 were counted at The Dalles and 100,483 at McNary. 

6. Squawfish totaling 11,504 passed the counting stations •. 

7. One sturgeon estimated to be 60 to 67 inches in length was 

observed passing the Washington ladder on 6 August. 

8. Lampreys totaling 67,914 were counted. No smelt were observed 

near Bonneville in 1966 nor since 1953.

9. The screen pit was drained and cleared of debris 3 and 4 Februar,y 

1966. Fall maintenance was initiated 15 November 1966. A large concentration of steelhead trout first observed 23 August were moved in containers to the foreb~ 15 and 16 November. 

10. The collection system was then unwatered and all vertical timber 

baffles in diffUsion chambers 18, 19 and 20 were removed. Bubble slabs 

and underpinnings of diffUsion chambers 1 through 8 of the ladder were 

replaced with gratings of 2 x 6 timbers separated by I-inch spacers. Two 

6-inch holes earlier drilled through approximately 7 feet of concrete 

between chamber 20 and the south fishlock worked well in unwatering the 

collection b~ into the fishlock drain tunnel where it was pumped out. 

The fixed l-inch-spaced vertical metal pickets on the upstream side of 

the fish counting fence were removed since they interfere With trash 

removal. Sandblasting and painting of the upstream regulating gate facilities continued and the ladder was rewatered 2 Februar,y 1967. 

Bradford Island Ladder and Powerhouse Collection Syst~m 

11. Work which began 1 December 1965 at the south end of the powerhouse collection system, including repair of auxiliar,y water valves 1". 

2 and 3" cleaning and painting of all exposed steel, elimination of 

vertical post diffUsion baffles" and installation of new 2 x 6 gratings. 

in these chambers and over about one-half of the collection b~ area, 

3 
Bonneville Dam 

was completed 7 Januar,y 1966 and this section of the powerhouse complex 

was rewatered. Extensive repairs were made early in 1966 on the curtain 

wall separating the powerhouse fish transportation channel and the draft 

tube stoplog slots. All wooden partition walls from units 0 through 6 

were replaced by 10 March in a manner mo~e resistant to attack by fungi. 

12. On 11 Januar,y a diver aided in placing stoplogs, and powerhouse 

diffusion chambers 4, 5, 6 and 7 were drained for removal of mud, debris 

and vertical posts from the auxiliar,y water chambers. New diffusion 

gratings and underpinnings were installed. The parition wall was repaired 

and this portion of the collection system was rewatered 28 Januar,y 1966. 

13. Stoplogs were installed at Weir 53 (the junction pool) and the 

A-Branch ladder was drained 14 Januar,y to permit reinforcement of weir 

crests and replacement of the old diffusion gratings with 2 x 6 material. 

Exposed metal was sandblasted and repainted. 

14. Diffusion chamber valves were renovated (all vertical diffusion 

baffles had been replaced earlier with concrete pillars now in common use 

at nearly all diffusion chambers on the Project). 

15. The A-Branch which had been drained to tailwater was rewatered 

3 Februar,y. 

16. Section 6 of the powerhouse collection system was drained 7 

Februar,y, the vertical baffle posts in diffusion chambers 12 and 13 

removed, and the bubble slabs replaced with the new type of gratings. 

These chambers were flooded 14 Februar,y and the stoplogs removed 18 

Feb~ary.

Bonneville Dam 

17. Installation of approximately thirty 8-foot high timber bulkheads 

constructed during the spring of 1966 for closing all unused powerhouse 

ffsh entry openings was completed 9 March. 

B-Branch Alterations 

18. On 1 December 1965 the raised weir cresto below weir 15 in the 

B-Branch were lifted out of the ladder to give a better flow at the lower 

end; none had been installed at the comparable location in the A-Branch. 

Observations of both areas in 1966 indicated satisfactory passing conditions for salmon. 

Special Biological Activities, Investigatio"lS, & Observations 

19. More aquatic vegetation was noted in the river than has been 

observed heretofore and the problem became acute in attempting to maintain a current of water through the fish counting fences. 

20. Oregon State University biologists under contract with U. S. Fish 

& Wildlife Service tagged several hundred salmon from the North Shore Trap 

during the period 6 April - 21 July and thereafter aided in capturing 

salmon for Sonar tracking experiments. 

21. U. S. Fish & Wildlife Service early in the run transported about 

500 Spring Chinooks from the Washington trap to the Tyee (Carson) hatchery. 

22. Personnel of the U. S. Fish & Wildlife Service and Oregon Fish 

Commission dipped thousands of fingerling salmon from intake gate wells 

at Bonneville, Ice Harbor, McNary, and The Dalles. Examination of marked 

"gate-well" fish at lower dams and at the mouth of the river appears to 

be giving important ichthyological information.

Bonneville Dam 

23. Project personnel conducted shad-holding experiments including 

studies using saline solutions. 

General 

24. Over a million people (1,077,400) visited the Bonneville area in 

1966. 

25- Large numbers of anglers fished for salmon, steelhead, shad and 

sturgeon in project waters during the various runs of these species. At 

the end of the calendar year, additional recreation and sanitar,y facilities 

were under construction to accommodate the heavy sports and visitor 

traffic. 

Fishway Operations & Maintenance Costs 

26. The total 1966 fishway operation and maintenance costs including 

routine fish counting but excluding research and other investigations 

were as follows:

Salmon 

27 • A total of 1,318,411 fish was counted at The Dalles Dam in 1966, 

including 567,009 salmonids, and 751,402 of miscellaneous other species. 

The ma.ximu.m number of salmon in arr:! one d~ was il,008 on 1 July. Of 

these, 8,436 were sockeye which also marked the peak of the sockeye run. 

28. Following is a brief summaxy of Salmonid counts:

30. A factor of 1.2 was applied to each d~'s count to compensate 

for fish passing during the lO-minute rest periods. Gates remained closed 

when counting was not being performedj no nighttime factors applied in 

1966. The unusual counting schedule in late February and through. March 

was placed in effect to gain knowledge of fish movement during peaking 

studies conducted at Bonneville and The Dalles projects. 

Fish Facilities Inspection, Alterations and Operations 

31. The folloWing resume presents periods of fishway inspection and 

overhaul: 

(1) 23 November 1965 - 25 February 1966. North I.a.dder was 

drained. Counting station hoist facilities were overhauled. 

New rollers were installed on the North Ladder upper regulating gates. 

(2) 1 - 11 March 1966. The East Ladder was drained for inspection and minor adjustments of the counting gate hoists and 

tracks. 

(3) 21 - 23 March 1966. The North Fish I.a.dder was shut down 

to adjust rollers on the counting board. 

8 
The Dalles Dam 

(4) 12 April 1966. Automation of the North Ladder upper regulating weirs was completed. By 20 April the same work had 

been accomplished at the East Ladder. The automatic weir 

regulating facilities worked perfect~ and maintained proper 

quanti ties of water in the ladders throughout the remainder 

of the season. 

(5) 9 - 16 November 1966. The North Ladder was again withdrawn 

from service for inspection and minor maintenance. It was 

reactivated 16 December, but auxiliar,y water was not reintroduced until the spring of 1967. 

Special Fishery Observations & Investigations 

32. U. S. Fish & Wildlife Service ~ersonnel conducted intake gate 

well fingerling studies from April through the summer and ear~ fall. 

33. Two fishway operators were required to maintain proper fishway 

regulations during the late Februar,y peaking flow tests which took place 

before the upper regulating weirs were automated. Tailwater and forebay 

levels fluctuations were large. 

34. A number of distressed shad fingerling with popped eyes were 

observed after passage through the navigation lock filling valves. 

35. At periods of heavy downstream movement of shad fingerlings, 

October and November, feeding gulls became active at the tailrace side of 

The Dalles (and Bonneville) powerhouse. 

Visitors 

36. Visitors to The Dalles Dam and recreation areas totaled 228,000.

Fish Facility Alterations 

40. The John Day pool will cause a rise in the tailwater elevation 

at McNary Dam. Modifications to compensate for the increased elevation of 

tailwater to the fish ladders were started in the fal1 of 1966 and will 

be completed in 1968. 

Special Fishe;r Investigations 

41. The supplementary spawning channel built in 1957 and operated 

by the Washington Department of Fisheries, under contract with the Corps 

of Engineers, continued to operate during 1966. After the spawning in 

the fall all traps and obstructions were removed from the channel. This 

work was completed by 31 December 1966. The Corps will continue to supply 

water and keep the channel free of weeds until late spring of 1967. By 

1 June 1967 a deter.minationwill be made by the district biologists as 

to the status of fingerling migration out of the channel. Steps will be 

taken to insure all migrants have left so the channel can be unwatered 

by 30 June 1967. 

42. The Bureau of Commercial Fisheries has been dipping gate wells 

at McNary Dam to check on size and markings of the salmonid fingerlings 

passing downstream.

No counting performed. 

Sample counting in four-hour periods, 

alternating between counting stations 

16 hours daily. The gate s of the 

ladder Where the last daily four-hour 

shift was spent were closed from 8:00 

p.m. to 4:00 a.m. PST. Next day when 

first shift opened them, opposite 

ladder remained open during this time. 

No counting performed. 

46. In conjunction with the discrepancies of fish counts between 

McNary Dam and Ice Harbor ... Priest Rapids Dams, some concern was expressed 

14 
Ice Harbor Dam 

as to the operating procedures. Oregon Fish Commission set up a program 

to determine desirable spillway patterns under various flow conditions. 

These flow patterns would be so set as to provide the greatest fish 

attraction to either the north or south shore ladder. The experiment was 

to be conducted 20 30 June. Due to the extremely low flows during this 

period of time, it was decided to defer the proposed experiment until the 

spring of 1967. 

47. Research by the U. S. Bureau of Commercial Fisheries was continued at Ice Harbor Dam to develop methods of protecting migrating fish 

passing downstream through turbines. Research in 1966 concentrated on 

the development of suitable equipment and techniques for evaluating effectiveness of potential fish protection measures. To date, two methods have 

beert explored. One method utilizes a funnel net attached directly to the 

draft tube exits of turbine 3 to obtain an index of fish mortality caused 

directly by the turbine. A second method consists of marked groups of 

fish released above and below the turbine and the recover,y of a percentage 

of the survivors of each group that enter the intake gate wells of the 

next dam downstream (McNar,y). 

Jishway Operation and Maintenance Cost
