the terminus of the survey because of a series of falls and the ex- 

 tremely steep gradient. Near the mouth the stream was about 30 feet 

 iride, discharging about 7$ c.feSo, and the water temperature was 5$«0 

 F. The gradient is steep throughout, and there is practically no 

 suitable spawning area, Wajnm Spring Creek is completely inaccessible, 

 and of no present or potential value to salmon, 



3H-(7). Canyon Creek ,— (August 26, I938; Wilding.) Canyon 

 Creek enters the South Fork of the Payette approximately 58 miles 

 above the mouth o The stream is about 9 miles long, of which 2 miles 

 were surveyed. It is of no possible value to saLnon above the tei^ninus 

 of the siirvey because of the extremely steep gradient. Near the mouth 

 the stream was 18 feet wide and discharging about 25 c.f .s. The grad- 

 ient is steep throughout, and there is practically no suitable spawning 

 areao Canyon Creek is completely inaccessible, and of no present or 

 potential value to salmon. 



Summary of Recommendations 



The completion of the Boise Project as presently contemplated 

 would render the restoration of the Chinook and blueback salmon runs 

 of the Payette River not only very costly but also doubtful of success. 

 The construction of fishways at Black Canyon Dam would be of little 

 benefit unless adequate facilities were provided at Smith Ferry, Cascade, 

 and the Payette Lakes. A number of large diversions wo\ild have to be 

 screened and there also would be the problem of maintaining adequate 

 stream flows at the time of salmon migration. No fish protective devices 

 or stream improvements are recommended for this system because it is felt 

 that efforts at salmon conservation would be more effective in certain 

 other localities.
