and at the upper end of the section is characterized by long, flat 

 bench lands. There is no cultivation along the river banks, but the 

 benches are used for stock grazing in the springo Tnese bench lands 

 are bounded by high cliffs and steep hills which are surmounted by a 

 high flat plateau on which are located several small towns such as 

 Melba, Idaho. 



The Cruffey Project of the Idaho Power Company is located at a 

 site about 12 miles downstream from the Swan Falls dam, or approxi- 

 mately U32 miles above the mouth of Snake River* The development of 

 this project is now underway, and includes the construction of a dam 

 about 10 feet high Present project plans do not include the instal- 

 lation of a fishway. 



From a point opposite Melba up to the town of Grand View, Idaho, 

 a distance of 35 miles, the Snake River flows through a deep canyon 

 where the walls are often precipitous and in some places, as in the 

 vicinity of Swan Falls, rise over 1,200 feet above the river bed. 

 There are a few narrow benches along the river where the banks are 6 

 to 15 feet high and composed of earth and rock, but in most places the 

 banks are formed by the high canyon walls. The canyon is surmounted 

 by wide expanses of flat, almost barren, sandy, sage-covered plateaus. 

 There is no cultivation in this section. Except for the pool area 

 extending three or four miles above Swan Falls dam, the stream gradient 

 is fairly steep The river bed is composed mainly of bedrock and 

 large rubble Shallow riffles are few and generally of poor quality, 

 and there is little suitable spawning area in this section, especially 

 above Swan Falls Large excellent resting pools are numerous,, Margi- 

 nal vegetation is sparse, consisting of sage, elderberry bushes, and a 

 few grasses. 



The Swan Falls dam and power plant of the Idaho Power Company 

 is located 10 miles above a point opposite Melba or approximately hhh 

 miles above the mouth of Snake River „ This dam is 30 feet high. It 

 is understood that a dam at this point first obstructed the passage of 

 anadromous fish about the year 1907. A poor fishway was provided, but 

 the runs above the dam were exterminated. The fishway was improved 

 about the year 1?U0, and it is now possible for fish to ascendo The 

 power plant is equipped with low-speed, reaction type turbines operat- 

 ing under a head of 2k feeto 



From a point above Grand View up to Hammett, Idaho, a distance 

 of U5 miles, the canyon opens into a valley which widens upstream. 



The C. J, Strike Project of the Idaho Power Company has been re- 

 cently granted a preliminary permit by the Federal Power Commission, 

 and it is understood that construction is to be started in the near 

 future. The project would include a dam across the Snake River at a 

 point about 1 mile downstream from the mouth of the Bruneau River. The 

 dam would be about 120 feet in height, and would not be provided with 

 fishways.
