4-0o Silver Creek » — March 6, 1937; Baltzo and Jobes.) Enters 

 the Yakima about one mile below Easton Dam, and is 7 miles longe The 

 discharre was 6 c.f.s. at the time of inspection, but during the greater 

 part of the year the lower portion of the course is practically dry, 

 rendering the stream of no value to migratory fish. 



4P. Kachess River . — (March 20, 1935; Shuman and Whjte leather.) 

 Joins the Yakima less than 1 mile above Easton Dam. It was surveyed 

 for 1 1/2 miles to the impassable storage dam at the outlet of Kachess 

 Lake. There was originally a natural lake at this site, and a crib 

 dam was installed at its outlet in 1905. This was replaced in 1911 

 by a 63 foot, rock-faced, earth-fill dam built by the Bureau' of Reclama- 

 tion. A good run of >)luehack salmon entered the lake until Mocked by 

 construction of the dam. There are still large sized landlocked blueback 

 or kokanee, ling, cutthroat, and rainbow trout in the lake. Runs of 

 salmon and steelhead no longer enter the stream. The tributaries above 

 the dam vfere not surveyed because the great fluctuation of the reservoir 

 level makes it improbable that a fishway will be built. The discharge 

 is now completely regulated. It is usualljr 200 to 1,500 c.f.s, from 

 April to October, and nearly dry during the rest of the year while 

 water is being impounded. 



4Q. Cabin Creek . — (April 19, 1937; Jobes and Baltzo.) Enters 

 the Yakima about 3 miles above Easton Damy and extends for 14 miles. 

 It had a flow of 50 c.f.s. during the spring run-off, but it is quite 

 low in the fall. The water supply for the tovm of Easton is diverted 

 from this stream, and the lov/er 2 miles has been channeled for flood 

 control. The stream therefore has little value to salmon and no i*uns 

 are reported.
