From Hammett upstream to Bliss, Idaho, a distance of about UO 

 mile 3, the valley is from six to two miles wide, flat in the lower part 

 and gently rolling above There are some suitable spawning areas con- 

 tained in this section 



The Bliss project of the Idaho Power Company includes a recently 

 constructed dam 10U feet in height located across Snake River at a 

 point approximately 5 miles downstream from the town of Bliss* The dam 

 is not provided with fish-passage facilities,, 



From Bliss upstream to Upper Salmon Falls, a distance of about 

 18 miles and the upper terminus of the survey, the gradient is moder- 

 ate to fairly steep. The river has an average width of about 320 feet 

 in this section, although it is narrower in the lower canyon portion* 

 The river bed is composed mainly of bedrock and large rubble, and there 

 is little suitable spawning area. There are numerous good resting pools. 

 The stream banks are steep, 12-30 feet high, and composed mainly of bedrock 

 and boulders* The marginal vegetation along the river banks is sparse, 

 consisting mainly of sage and a few willows. 



Lower Salmon Falls and a power dam of the Idaho Power Company is 

 located about two miles downstream from Hagerman, Idaho, or approximately 

 565 miles above the mouth of Snake River. The natural falls at this 

 point, 10-12 feet high, are surmounted by a power dam. The combined falls 

 and dam formerly constituted the upstream limit of possible anadroraous 

 fish migration in the Snake River, This migration limit has been moved 

 downstream by the previously described power projects. 



Upper Salmon Falls and another power dam of the Idaho Power Company 

 is located about 9 miles above Lower iSalmon Falls, The natural falls or 

 rapids at this point are very low, but are surmounted by a concrete dam 

 10 feet high, A fishway is located near the center of the dam, and is 

 passable at all times. 



Although this section of the Snake River is inaccessible to ana- 

 dromous fish, it retains considerable value for resident trouto It is 

 assured of a large constant supply of cold water by the discharge of the 

 "Thousand Springs" a short distance above Upper Salmon Falls, 



1, Malheur River, — (July 19-25, 19^2j Parkhurst.) The Malheur 

 River enters the Snake River just below the town of Ontario, Oregon, or 

 approximately 359 miles above the mouth. The main river extends for a 

 distance of about 167 miles. The entire watershed drains an area of more 

 than U, 750 square miles in eastern Oregon, principally in Malheur County 

 and the Malheur National Forest, The headwaters are high on the eastern 

 slope of the Blue Mountains,
