a large amount of good spawning area above the town of Indian Valley, 

 l5 miles above the mouth, and it was reported that in earlier years 

 Chinook salmon and steelhead spanmed all along the stream from the 

 vicinity of Indian Valley to the headwaters some 2li miles above. Al- 

 though the Chinook salmon have been greatly depleted, it was reported 

 that the remnants of these r^ons still utilize this upper portion. 

 The appearance of the late summer chinooks is now dependent upon satis- 

 factory water conditions in both the lower Little Weiser River and in 

 the main stream. Since these conditions are often unsatisfactory at the 

 time of the spa^vning migration, the stream is of little present or po- 

 tential value to salmon. Water conditions are much better in the spring, 

 and the headwaters portion rrith its numerous tributaries has good po- 

 tential value for a large run of steelhead, 



2G-(1). Grays Creek . — (Not surveyed) Grays Creek enters the 

 Little TTeiser River approximately 11 miles above the mouth. The 

 stream is about 25 miles long, A single diversion takes the entire 

 flow during the irrigation season, leaving the lower portion of the 

 stream bed practically dry. Water is carried into Grays Creek from 

 diversions on Fall Creek and the Little Weiser River, Without these 

 two supplemental supplies for irrigation, Grays Creek would be dry 

 for almost its entire length in late summer. Because of its use for 

 irrigation, the stream is of no value to salmon and of little value 

 to steelhead, 



2H. Pine Creek . — (August 27, 19Ul; Frey and Bryant.) Pine 

 Creek enters the Weiser River approximately 36| giiles above the mouth. 

 The stream is about l5 miles long, of which the lower 7 miles were 

 surveyed. Near the mouth it was 13 feet wide, discharging between 

 10 and 15 c,f,s,, and the water temperature was 58,0°Ft The gradient 

 is moderate, and increases above the terminus of the survey. The 

 stream bed was heavily silted for a distance of h-z miles above the 

 mouth. There were 5,000 square yards of suitable spawning area, con- 

 stituting approximately 10 percent of the total bottom in the portion 

 surveyed. There were 21 small irrigation diversions. The diversion 

 dams were all small, low structures. Most of these dams were of 

 temporary construction, although there were several which were barriers 

 to fish at low water. The stream formerly supported good runs of 

 Chinook salmon and steelhead. It was reported that a few chinook 

 salmon still appear in most years, and that there is a small spring 

 run of steelhead. Because of its extensive agricultural use. Pine 

 Creek has little present or potential value as a salmon producer, 



2-1. Spring Creek , — (Mot surveyed.) Spring Creek enters the 

 Weiser River approximately 37 miles above the mouth. It has one 

 small irrigation diversion. Because of its small size the stream is 

 of no value to salmon. 



2J, Rush Creek . — (Not surveyed.) Rush Creek enters the 

 Weiser River approximately 37| miles above the mouth. The stream 

 is about 17 miles long, A fowerplant and an impassable falls are 

 located about 9 miles upstream. There were 21 small irrigation
