formerly supported a large run of Chinook salmon. The history of the 

 depletion of the run is identical with that of Marsh Creek. At pre- 

 sent it supports a very small salmon populationj U1+ live adult chi- 

 nooks, U dead spawned-out chinooks, and i|.6 nests were seen during the 

 survey, A spring run of steelhead trout was reported. The stream is 

 of small value as a salmon producer at present, but it has great po- 

 tential value. 



lC-Cl2)b-i, Banner Creek .— (July 28, I9UI; Frey and Bryant.) 

 Banner Creek enters Cape Horn Creek 5^ miles above the mouth. The 

 stream is approximately U miles long, of which about 1 mile was sur- 

 veyed. It is of no possible value to salmon above the terminus of the 

 survey because of the steep gradient and low volume of flow. Near the 

 mouth the stream was l5 ft. wide, discharging about l5 c.f.s«, and 

 the water temperat\ire was U9.0 F, The gradient is slight to moderate 

 in the lower mile, and becomes steep above, There were 1,900 square 

 yards of suitable spawning area, constituting approximately 3U percent 

 of the total bottom in the portion surveyed. A log jam located a 

 short distance above the terminus of the survey was considered to be 

 a barrier to fish. Although too small to have ever accomodated a 

 large rxm, the stream formerly supported a much larger salmon popula- 

 tion than at present, ^he history of the depletion of the r\jn is 

 identical with that of Marsh Creek. The present salmon run is very 

 small; U live adult chinooks, 1 dead spawned-out Chinook, and 7 nests 

 were seen during the survey* A spring run of steelhead trout was 

 reported, ^he stream is of little value as a salmon producer at present, 

 but it has some potential value, 



lC-(12)c, Khapp Creek , — (July 25, 19^1; Bryant,) Knapp Creek 

 enters Marsh Creek 10 miles above the mouth. The stream is approximately 

 15 miles long, of which about 1 mile was surveyed. The small volime 

 of flow and numerous beaver dams located about 2 miles above the .mouth 

 render the stream of little value to salmon above that point. Near the 

 mouth it was 15 ft. wide and discharging about 10 cf.s. '^'he gradient 

 is slight to moderate in the lower 3 miles, and becomes steep in the 

 upper part. There were 1,200 square yards of suitable spawning area, 

 constituting approximately 26 percent of the total bottom in the portion 

 surveyed. Water conditions at the tine of the spawning migration affect 

 the amount of spawning area available, Kn^pp Creek formerly supported 

 a good number of chinook salmon for a stream of its small size. The 

 history of the depletion of the run is identical with that of Marsh Creek, 

 A few salmon still enter the stream; no spawners and only two nests were 

 seen during the survey, A spring run of steelhead trout wqs reported. 

 The stream is of little value as a salmon producer at present, but it 

 has some potential value, 



1C-(13).. Bear Valley Creek , — (July 2^-27, 19Ulj Frey and Bryant,) 

 Bear Valley Creek enters the Middle Fojrk approximately IO6J miles above
