lC-(7)a. Big Pistol Creek .— (July l6, 19Ulj Bryant.) Big 

 Pistol Creek enters main Pistol Creek about 32 miles above the mouth. 

 The stream is approximately l5 miles long, of -which the lower 6 miles 

 were surveyed. Near the mouth it was 18 ft. wide, discharging about 

 80 c.f.s., and the water temperature was 5l.0°F. The gradient is fair- 

 ly steep except for a few small flats. There were 8,^00 square yards 

 of suitable spawning are* constituting approximately 13 percent of the 

 total bottom in the portion surveyed. Most of the good spawning area 

 was found in the lower 3 miles* Two log and debris jams and numerous 

 beaver dams found in the upper half of the portion surveyed were very 

 difficult for fish to ascend, and were probably barriers at low water* 

 The U.S. Forest SeinrLce reported that a small run of Chinook salmon 

 formerly entered the stream, but that no salmon had been seen here for 

 several years, A fair run of steelhead trout was reported to enter in 

 the spring. The cause of the present salmon depletion is not known, 

 but may be due partly to severe and recurrent flash floods. Big Pistol 

 Creek extends through a remote area, and the salmon run has not been 

 subjected to molestation by man. It is of no value as a salmon pro- 

 ducer at present, but has some potential value and appears capable of 

 supporting a fair run, 



lC-(7)b, Little Pistol Creek .— (July l6, 191x1; Frey.) Little 

 Pistol Creek enters mairt Pistol Creek about 3j' miles above the mouth. 

 The stream is approximately 13 miles long, of which the lower 7 miles 

 were surveyed. Near the mouth it was about 30 ft. wide, discharging 

 between 75 and 80 c.f.s,, and the water temperature was 5l«0 F. The 

 gradient is slight to moderate in the lower 2 miles, increasing up- 

 stream until above the terminus of the survey it is too steep for the 

 stream to be of possible value to salmon. There were 13,000 square 

 yards of s\ii table spfl-wning area, constituting approximately 15> percent 

 of the total bottom in the portion surveyed. Several log and debris 

 jams were c onsidered as probable barriers to fish at low water. The 

 U. S. Forest Service reported that a good run of Chinook salmon formerly 

 entered the stream, but that no salmon had been reported for the past 

 several years, A fair run of steelhead trout was reported to enter in 

 the spring. The salmon run has not been subjected to molestation by 

 man in this stream. No salmon were seen during the survey. Althoi^ 

 Little Pistol Greek is of slight or no value as a salmon producer at 

 present, it has some good spawning area and appears capable of sup- 

 porting a fair run, 



lC-(8). Rapid River ,— (July 17-18, 19Ulj Frey and Bryant.) 

 Rapid River enters the Middle Fori: approximately 78 miles above the 

 mouth. The stream is about 20 miles loijg, of which the lower 125- miles 

 were surveyed. Near the mouth it was about 30 ft. wide, discharging about 

 1$0 c.f.s., and the water tertiperature was 58,0°F. There was little 

 decrease in volime upstream in the portion surveyed, the flow at the 

 upper terminus being about 120 c.f.s. The gradient is steep to moder- 

 ate. There were 28,000 square yards of s\ii table spawning area, consti- 

 tuting approximately 1$ percent of the total bottom in the portion
