~ lampreys whioh bad passed weir 41 counting station became weak in

Aotivities and Observations 

Fish Lookl 

3'1. ot the twa fish looks at Bonneville Dam, only- the Washington 

shore tish lock was operated 1D 1966 to raise fish to torebq level. 

This look _a operated each dq in Maroh prior to the oompletion ot the 

ladder portion ot the north shore la'boratery. The Washington ahore tish 

ladder was rewatered on March 26, 1956. 

Powerhouse and Bradford Island Auxiliary 'Water Soreens 

38. The new trash racks at the powerhouae auxiliary watar intake 

were completed in February 1965 and proved highly- satisfaotory throughout the season. AI a resut t, the til tar aoreens were much more ettective, cleaning wall eallier, and larger quantities ot auzi1iary .. ter 

could be used. 

39. The Bradford Island and powerhouse sore_s are .tation&ry' 

and are cleaned by hand.-.shiDg one or more times a d.a¥ during periods 

of heavy accumulations ot debris. It i8 necessary at times to throttle 

the primary 'ftl TeS soon attar soreen--.shing in order to protect the

6S. In April. 491 spring ohinook salmon were caught in the Washington shore tish trap and trlDsported in apeoial ta.Dk: truoks to the !yee 

tish oultural. station by the U. S. nsh and 'Wildlife Servioe tor the 

purpo.e ot s~ng artifioial transplantations from upstream to lower

ohiDook salmon in Wind River. These tish were held through the spring 

and ear17 SUDJler in a apeoiall;Y-OODStruoted pond. and sp&1II1ed in August

64. Also in April. in an experimct oonducted bY' the 'Washington 

Department ot I'1.sheries. 260.000 tiD-olipped tingerling. released from 

upstream hatoheries, are transported by' truck to below the cia. then 

transferred to a speoial1Y'-oonstruoted barge with free-circulating water 

md released at dift.ret points along the river near the ooean. 

65. A greater quantity ot .ter was spilled into Tanner Creek

to enter the hatchery holding ponds from the river. 

56. In October, ft_ 40.000 p01Bl.ds of young salmon fingerlings were 

released. from the Little White Salmon hatchery above Bonneville Dam. 

200 or more Bea gullB were observed teeding on the fiBh at the powerhouse.

58. The U. S. Fish and Wildlife Servioe oonducted a number of tests 

in the spring of 1955 on equal numbera of anaesthetized. tattooe4 fingerling sal.mon and 11.,. tingerU.Dga (tattooed with a cHtter8l'.l.t mark) released 

through the powerhouse turbines. A quick-release tyke net _s mounted on 

the dratt tube trap to recapture the fish. The purpo8e of the experim8l1t 

-a to determme whether such a net oould oapture both live and. dead tish. 

Ma.l:ty'more live than anaesthetized fingerlings 1I8re reoaptured in thil 

experiment. 

Adul t Blueback Tagging Experim.8I1t

the north shore spring ohinook trap and transported to Garrison Eddy

-,.. 

.' . 

below Bonneville Dam where they were tagged with Petersen disk tags and 

released. Only about 60 peroent re-asoended the fish ladders. This experiment _s performed by the U. S. Fish and Wildlife Servioe to compare the 

distribution of fish returning upstream. via the several tish_y _tranoes 

and fish ladders with similar tests oonducted at Rook: Island Dam. 

Low Pressure Test 

60. As an origiDal. part of the fingerling suniTal. experiment., 

faoi1i tie. were constructed at the Hydraulio Laborato~ to subject small 

fish to pressure. Wild fish, oaptured in the fingerling by-passes, were 

used and subjected to pressure which _s immediately lowered to the vacuum 

side of atmospherio. Only a ttnl preliminary uperiaents were made in 1966. 

It is p1armed to resume these experiments at a later date. 

Sphaeroti1us Growth Tests 

61. Sphaerotilus i. a lower torm of plant lite which torma a slime, 

ruinous to fish nets in the river, and utilize. the sugars fOlmd in waste 

sulfite liquor pollutant. Studies pertaining to the growth of 

Sphaerotil us in _ste sulfite liquor-fed _ter were oonducted at BoDl18Ville 

Dam. during the latter part of August and early Sept_ber by' the 'Washington 

state Pollution Oontrol Oommission in an experimental facility temporarily 

located adjacent to the powerhouse fingerling by'-pasa trap and supplied 

with _tertlow trom the by'-pass. Different concentrations of _ste sulfite liquor were fed into separate culture trough. to learn about the 

growth rate of Sphaeroti1us above the paper plants situated along 

Columbia River.
