impassable 20-foot falls. The stream t/£.s about 20 feet wide and 

 yias discharging 30 c.f.s. The gradient is steep, and tt.ere is suf- 

 ficient salmon snavming area below the falls to accommodate onlj^ 

 about 350 fish. No salmon were seen or reported. A few small cut- 

 throat trout were observed, 



252E-(ll). Simpson Creek . — (july 10, 1938; Langton.) Enters 

 the Middle Fork of u'illamette approximately 60 miles above the mouth « 

 The stream is about 6 miles long, of Virhich the lower 1-g- miles viere 

 surveyed. It v/as discharging about I5 c.f.s., and the temperature 

 was 52° F. The gradient is steep, the stream being a succession of 

 cascades and lov*- falls, with numerous fallen logs. There is little 

 spa'uming area, and the stream is of no value to salmon, and only of 

 slight value to trout. 



25EE-(12). Staley Creek .— (July 9, 1938; l^rton.) Enters the 

 Middle Fork of Willamette approximately 61 miles above the mouth. 

 The stream is about 14- miles long, of T/hich the lovrer 3*3 miles were 

 surveyed up to an im}5assable 20 foot falls. It vras about 30 feet 

 wide, discliarging 57 Cof.So, and the water temperature was 54° F. 

 The stream course extends through a narrow valley with alternate flat 

 bottom lands and deep, steep, bedrock gorges in Y/hich there are many 

 large clear resting pools. 



A log jam 1 mile above the mouth was considered impassable at 

 loviT v/ater. There are many smaller log and debris jams, falls, and 

 cascades 'in the stream below the falls, including tvro T/ide bedrock 

 aprons that may be barriers to fish at lov; vfater. 



The stream contains some good salmon spavming areas, estimated 

 sufficient to accommodate 400 salmon spavmers below the falls. Good 

 runs of spring chinook salmon were reported to formerly enter the 

 stream. Staley Creek supports a good population of resident trout, 

 especially in the upper section.

 ^0*^ F. In the lower 1-| miles the stream extends through a sv/ampy 

 valley containing many flood channels. Above this section the stream
