and cascades. The stream was 36 feet wide at the mouth, and discharg- 

 ing about 80 o.f.s. on July 20, 1941. On Oct, 8, 1942, the discharge 

 at the mouth r/as about 50 o,f,s. There were 45,000 sq, yd, of suit- 

 able spawning area, constituting approximately 62 percent of the total 

 bottom, A log jam 500 yards below the outlet of Big Redfish Lake was 

 found to be passable with difficulty. It was reported that no chinook 

 salmon enter the stream and none of this species was seen during the 

 survey. Wo blueback salmon were seen in the stream, but they were ob- 

 served spawning in Big Redfish Lake in October, 1942, It was reported 

 that the bluebacks do not spawn in Redfish Lake Creek, but that the 

 resident form of the sane species, locally knovm as "Little Redfish" 

 migrate from the lakes into the stream in August to spawn. The chief 

 value of Redfish Lake Creek to salmon appears to be its use as a 

 passageway by the small, greatly depleted run of blueback salmon that 

 enters Big Redfish lake. 



Summary of Recommendations 



Because of the greatly depleted condition of the salmon 

 populations in the upper main Salmon River and upper I.iiddle Fork, 

 every effort should be made to protect and facilitate the natural 

 spav/ning of the remnants of these runs. 



On the Lemhi River a fishway should be constructed from 

 the tailrace to the forebay of the IdaJio Power Com.pany's plemt at 

 SaLi.on, Idaho. An irrigation diversion dam located about 7-g- miles above 

 the mouth should also be provided with a fishvray and the diversion 

 screened.
