to moderate in the lower part, and becomes fairly steep above the 

 terminus of the survey, ■'^'here were 3*100 so. yd, of suitable spawn- 

 ing area, constituting approximately 20 i)ercent of the total bottom 

 in the portion surveyed. No salmon were seen during the siirvey, 

 and it was reported that none enter the stream. Although not capable 

 of supporting a large run because of its small size. Cache Creek has 

 some potential value to salmon. 



ID, Panther Creek, — (July 11, 19Ulj Parkhurst and Zimmer,) 

 Panther Creek enters the main Salmon River approximately 203 miles 

 above the mouth. The stream is about U3 miles long, of which IO2 

 miles were surveyed. The lower part, from the mouth to the conflu- 

 ence of Napias Creek, a distance of about 20 miles, was not survey- 

 ed in detail because it was rendered extremely turbid by the discharge 

 of mining silt from Napias Creek. The stream bed is composed largely 

 of bedrock and large rubble for a distance of 22| miles above the 

 mouth, and there is little suitable spawning area in this lower portion. 

 Near the mouth the stream was UO feet wide, discharging about 1^0 c.f ,s,, 

 and the water ter.perature was 62,5°F, Just above the mouth of Napias 

 Creek the stream was about 30 ft, wide, discharging about 30 c.f ,s., 

 and the water temperature was $3.0°F. The -jradient is fairly steep in 

 the lower part of the stream, becoming moderate in the surveyed jxjrtion. 

 The upper 8 miles of the portion surveyed has a very high concentration 

 of suitable spawning area. There were 82,000 sq. yd. of s\u.table 

 spawning area, constituting approximately h^ percent of the total 

 bottom in the portion surveyed. The stream is of little possible 

 value to salmon above the terminus of the s"'jrvey because of its small 

 size. Three low irrigation diversion dams, oneabandoned mining diversion 

 dam, and several beaver dams and log jams were foiir.d. None of these 

 were total barriers to fish, but two of the irrigation dams and a log 

 jam appeared to be passable only with difficulty at low water stages. 

 Only one irrigation diversion dam was in operation, the ditch with- 

 drawing about 1 c,f ,s. Panther Creek formerly supported a good run 

 of Chinook salmon. It was reported that the run has declined steadily 

 in recent years. At present very few salmon enter the stream j four 

 adult chinooks were seen during the survey , It is of slight value as 

 a salmon producer at present, but has good potential value, 



ID-(l), Napias Creek . — (Inspected July 11, I9UI; Parkhurst and 

 Zimmer.) Napias Creek enters Panther Creek approximately 20 miles 

 above the mouth. The stream is about 13 miles long. Near the mouth 

 it had an average width of more than 20 feet, and was discharging about 

 90 c.f.s. The gradient is e:ctremely steep. The stream is inaccessible 

 to salmon a short distance above the mouth because of the many falls and 

 cascades. The water was extremely muddy at the time of observation, 

 the stream carrying a large amount of silt from gold mines at Leesburg 

 in the headwaters, Napias Creek has practically no suitable spawning 

 area, and is of no present or potential value to salmon.
