surveyed The U. S, Forest Service reported that a small run of 

 Chinook salmon had entered Rspid River in past years o No salmon 

 were seen during the surveyo A small run of steelhead trout was 

 reported to enter in the spring. The lower portion of the water- 

 shed has been denuded by fire, and the stream is subject to 

 damaging flash floods. Severe erosion of the watershed and banks 

 was observed in. many places. Although the stream is of little 

 value as a salmon producer at present, it has excellent potential 

 value and should support a good run, 



lC-(9). Soldier Creek ,— (July 21, 19Ulj Frey.) Soldier 

 Creek enters the ItLddle Fork approximately 8S2 miles above the 

 mouth. The stream is about 8 miles long, of which the lower 3 miles 

 were surveyed. It is of no possible value to salmon above the 

 upper terminus of the survey because of the increasingly steep grad- 

 ient and numerous beaver dams. Near the mouth the stream was about 

 1$ ft, wide, discharging between 30 and Uo c,f,s,, and the water 

 temperature was US.O F, The gradient is fairly steep. There were 

 900 square yards of s^oitable spawning area, constituting approximately 

 5 percent of the total bottom in the portion surveyed. Several log 

 and debris jams were considered to be passable to fish only with 

 difficulty. There was no pollution at the time of the survey, but 

 mine operators expected to have a quartz mill operating at a point 

 ^ mile above the mouth in the year 19li?, It was reported that no 

 saLnion or steelhead enter the stream. No salmon were seen during 

 the survey. Soldier Creek is of no present value and of little 

 potential value as a salmon producer, 



IC-(IO). Slkhorn Creek ,— (July 21, 19Ulj Frey.) Elkhorn 

 Creek enters the Middle Fork approximately 88 miles above the mouth. 

 It is a small stream, intermittent in the upper portion. The grad- 

 ient is fairly steep, and increases upstream. Several bad log and 

 debris jams were found, including one located 1 mile upstream which 

 was considered a total barrier to fish. There were less than 100 

 square yards of suitable spawning area. The stream is of no present 

 or potential value to salmon, 



lC-(ll), Sulphur Creek , — (July 23, 19hl; Frey.) Sulphur Creek 

 enters the Middle Fork approximately 9U-| miles above the mouth. The 

 stream is about 19 miles long, of which the lower 10 miles were sur- 

 veyed. Near the mouth it was 30 ft, wide, discharging about 60 c,f,s,, 

 and the water temperature was $3»0 F, The gradient is moderate for 

 the most part, becoming fairly steep above the terminus of the survej'. 

 There were 37,000 square yards of suitable spawning area, constitu- 

 ting approximately 27 percent of the total bottom in the' portion sur- 

 veyed. The watershed in the first 3 miles above the mouth was burned 

 over in I9U0, This area was covered with fallen trees, and several 

 log jams had begun to formo The lower part of the stream should be 

 checked for obstructions after each spring high-water ceriod to 

 insure free access to salmon. Sulphur Creek is an excellent cbinook 

 salmon streai^ and supports a fair run. One hundred twenty-eight
