including 619,923 salmonids and 500,483 of miscellaneous other species. 

The most salmon to be recorded in one day was 16, 597 on 2 September and 

included 10,138 chinook, 4,483 coho, 1,972 steelhead and 4 sockeye.

Miscellaneous Other Species 

4. Non-salmonid species moved in maximum abundance on 6 July, when 

15,389 shad and 5,280 of mdscellaneous other species were recorded for a 

total of 20,669. 

5. Shad numbering 294,078 passed into the Bonneville forebay. Of 

these, 231,107 were counted at The Dalles, 123,136 at John Day, and 26,247 

at McNary. 

6. The squawfish tabulation of 19,605 is the highest for the past 

8 years. However, it is below the 3l-year average of 37,421 for this 

species. 

7. Three sturgeon were counted at the Washington station.

collection bay. A hole 6 inches wide by 5 feet high was discovered and 

corrected 25 January 1969 in the west end of the picketed leads which 

guide fish to the Bradford Island counting station. This hole undoubtedly 

has contributed for perhaps several years to discrepancies in fish counts 

between Bonneville and The Dalles projects.

10. Approximately 500 spring chinook salmon were transferred from the 

Washington ladder to the U. S. Fish & Wildlife Service Carson Hatchery 

during April. 

ll. A mono-filament gillnet containing several dead chinooks was 

recovered from where it had washed against the upstream face of the powerhouse, and was confiscated by Oregon State Police.

on 14 June. To compensate f'or the diminished amount of attraction water, 

twelve powerhouse collection system fish entry ports were closed leaving 

13 open. In addition one of the two south spillway fish entrances and two

east and two west powerhouse entrances were also closed, leaving one attraction channel open at each of the 3 loca~ions. The unit was restored to

April and for four days no fish passage was possi~le u~ti~ the pool " 

rea.ched the proper elevation to operate the fishways. On 2Q April this 

level was reached and a few hundred fish were passed. Over the next few -, ' 

days the numbers passing remained about the same whereas at this time 

thousands of fish should had been passing. The Corps and the fishery 
John Day Dam 

agencies jOintly engaged in a heavy on-site effort in order to so~ve the .... ". 

prob~em. Fish collection facilities are designed to function best when 

the powerhouse is in full operation. At this point in time, no power 

units were yet operative and the entire river flow was being passed over 

the spillway. Adjustments were made in spill patterns to improve the 

fishwa.y entrance conditions, flows were manipulated between night and day .. 

time releases, various difficulties affecting the pumping of attraction 

water were rectified, and hydraulic conditions in the powerhouse collection 

system were balanced out to provide suitable attraction and transportation 

... velocities. On 26 April, the count of salmonids passed over John Day rose 

to 2,418 followed by 7,702 on the 27th and a record 11,104 on the 28th. 

Although there was a delay of from a few days to about 12 days for some 

fish, 77,000 spring chinooks successfully passed John Day to provide an 

escapement upriver that was substantially better than average. 

Nitrogen SUpersaturation 

21. later in the summer there was evidence of nitrogen supersaturation 

in the river water. As water plunges over a spillway it contributes to this 

condition by entraining air containing about &Y~ nitrogen and driving it to 

'. 

sufficient depth where pressure causes the gas to become dissolved in the 

water in supersaturated concentrations. FiSh exposed to such water pick 

up the dissolved gas through their normal. respiratory processes. If the 

fish stay deep, the excess gas will be gradually eliminated and no harm 

is done. However, if fish surface or remain in shallow areas for an 

extended time, the dissolved gas comes out of solution in the blood and 

causes bubbles that block or restrict the respiratory system. This can

McNARY DAM 

Fish Passage 

26. A total of 712,515 fish was counted over McNary Dam in ,1968. 

Of this number, 453,535 were salmonids and 258,980 nonsalmonids. The 

greatest number of salmonids for any one day was 10,706 on 13 September. 

The combined maximum dai~ count of all species was 12,731 on 3 July. 

The predominant miscellaneous species was the sucker (192,929).

~. The Cooperative Fishery Unit, Bureau of Sport Fisheries and 

Wildlife has terminated its studies at the McNary spawning channel. 

The distance from the University of Idaho, at Moscow, was too great to 

effective~ operate the planned experiments in preditor-prey relationship. 

28. The Pasco Field Office of the Bureau of Commercial Fisheries 

will operate the spawning channel for temporary rearing and release of 

coho salmon. 

29. Research to develop a turbine bypass for young salmon and trout 

also 'continued. Submerged orifices, installed at McNary Dam by the Corps 

of Engineers, were very successful when checked during the last half of

31. A total of 329, 133 fish were counted over Ice Harbor Dam in 1968. 

Of this number 188, 456 were salmonids and 140, 677 non-salmonids. The

32. During the spring of 1968 experiments for spilling patterns were 

carried out as in 1967. The efficiency of fish passage is favored With 

the crowned spill. 

33. Research to determine mortality of fingerlings in the vicinity 

of dams was continued at Ice Harbor Dam. Results showed that the recovery 

of experimental fish from the intake gatewells of the next dam downstream 

is a satisfactory technique for e~timating relative mortality of several 

groups of fish. Samples of fish taken by purse and beach seines yielded 

the same data, shOWing that results were not biased by the sampling techniques. Ana~sis of the data showed that, in addition to losses caused 

by turbines, significant mortality from predation is sustained by fish

that enter slack-water areas downstream of non-overflow sections of the darn. 

Development of a traveling screen for guiding up to 80 percent of 

the young fish out of turbine intakes and into gatewells was ahead of 

schedule by the end of the year. Engineering studies of a traveling screen 

to be tested at Ice Harbor Dam were completed and hydraulic model studies 

of the device in a model of an Ice Harbor turbine intake were well along.

orifices at the sides carry most of the ladder flow. Smaller 

orifice in center is primarily for use of shad and has since 

been revised.
