little present value as a salmon producer, the twenty five chinook 

 spawners that were rescued and placed above the dam in 193U prob- 

 ably constituting the entire run of that species. However, it 

 has considerable potential value for salmon, as indicated by the 

 remarkable extent to which the steelhead run has been able to sur- 

 vive. In order to re-establish a run of salmon in the stream it 

 would merely be necessary to regulate the flow of water over the old 

 power dam so as to provide a passageway for the adult fish and maintain 

 a sufficient flow for the passage of the downstream migrants. The 

 hazards to all the fish populations would be greatly reduced by the 

 screening of all the water diversions. The stream is a valuable 

 producer of steelhead trout. The value of this species has been in- 

 creasingly recognized in recent years, and the stream warrants pro- 

 tective measures from the standpoint of the steelhead population 

 alone . 



10A. George Creek .— (April 27, 1937; Hanavan.) George Creek 

 enters Asotin Creek 3£ miles above the mouth and extends for about 

 25 miles. At the time of observation it was discharging about 35 

 c.f.s., which was practically flood stage. In the late summer the 

 stream becomes nearly dry in the lower section, although it always 

 maintains some flow. The water temperature at the mouth was U6°*» 

 The gradient is fairly steep, especially in the upper section. The 

 water was turbid at the time of observation, due to spring freshets, 

 and therefore a good evaluation could not be made of the stream bed. 

 However, there are numerous good shallow riffle areas suitable for 

 spawning, and a few large resting pools. There is little stream 

 cover in the lower 2 miles, but upstream the course extends through 

 narrow, rocky canyons bordered by pine forests, providing increas- 

 ingly better stream protection. 



Due to the low water conditions in summer George Creek is 

 of little possible value to salmon. A few steelhead spawners may 

 utilize the stream, but its chief value is for resident trout, 

 which are numerous in the upper reaches* 



10B, Charley Creek .— (April 2$, 1937 J Hanavan.) Charley 

 Creek enters Asotin Creek approximately 13 miles above the mouth 

 and extends for about 15 miles. At the time of observation it had 

 an average width of 8 feet, and was discharging about 10 c.f .s. 

 The flow was reported to drop to about 5 c.f.s. during the summer 

 months, and is maintained by numerous springs in the headquarters. 

 The water temperature was 56°F. at a point near the mouth. The 

 gradient is fairly steep throughout the course, with some cascades. 

 There are some good riffles and many small patches of spawning area, 

 especially in the lower h miles. The stream bed was estimated to 

 consist of 50 percent large rubble, U0 percent medium rubble, and 

 10 percent small rubble and gravel. The entire course extends 

 through narrow, steep-walled canyons, with good cover along the 

 banks. A small unscreened irrigation ditch near the mouth diverts 

 about 1/2 c.f.s.
