but at a lava sink 4 miles upstream the flow was reduced to 3 c.f.s. 

 The water temperature was 46°F. An 8-foot falls 1 mile above the 

 mouth appears impassable. There is little suitable spavming area. No 

 salmon were observed^ and persons familiar with the stream reported tliat 

 they had never seen or heard of any salmon using it. Neither is it 

 of value as a troat stream. 



25EfD-(19). Scott Creek . --and 25DI>-(20). Boulder Creek , are both 

 small streams entering the McKenzie 71^ and 72 miles above the mouth. 

 They were considered to be of little possible value to salmon^ and were 

 not surveyed. 



25DI>-(21) Deer Creek .— (July 21^ 1938; Morton.) Enters the 

 McKenzie ''■ miles belr^'-; the Smith River bridge, or approximately 75 

 nrjies a.'DO'ie -he \\cutn« The stream is about S miles long, of inrhich the 

 lower 2 miles were surveyed. The discharge was 32 c.f.s., and the 

 irater temperature 58-59° F. The gradient is moderate, and there is a 

 fair amount of suitable spawning area, sufficient to accommodate about 

 AGO salmon in the section surveyed. However, numerous log jams prob- 

 ably render most of the spawning area inaccessible^ and the stream was 

 considered to be of little present value to salmon. Deer Creek is a 

 good trout stream; fingerlings virere abundant, and numerous 6-inch and 

 a few 12-inch rainbow trout were seen. 



25DD-(22). Qlallie Greek .— (July 19, 1938; Langton.) Enters the 

 McKenzie 77 miles above the mouth, and is 2 miles long, originating 

 in two large springs gushing out of a mountain wall. The stream has 

 an average width of 25 feet, and was flowing 70-80 c.f.s. This is one 

 of the coldest streams encountered on the survey, the temperature 

 being 41°F. , at the mouth, and 38°F, at the source. It is a typical 

 torrential mountain stream, having a steep gradient and a bed composed 

 chiefly of large rubble. There is little salmon spawning area. No 

 runs have been reported, and it is improbable that salmon ever entered 

 the stream. A few small trout were seen. 



25DD-(23). Anderson Creek .— (July 19, 1933; Iknavan.) Enters the 

 McKenzie I/4 mile above Olallie Creek, and is 6 miles long. The stream 

 was discharging 35-40 c.f.s., and the water temperature was only 44°F. 

 The gradient is steep in the lower 1/2 mile below the road crossing. 

 Above this point the gradient is slight in an open mountain meadow 

 section, and the stream bed is about 80 percent sand. This clear flov;- 

 ing stream is supplied mainly by springs in the mid-section, the upper 

 32 miles having an intermittent flow in a lava sink area. Because of 

 lack of suitable sjmwning area and the prevailing low water temperatures 

 the stream is of little possible value to salmon. 



25DD-(24) Smith River . — (July 19, 1938; Hanavan.) Enters the 

 McKenzie 79 miles above the mouth. The stream is 10 miles long, of 

 which the lower 2 06 miles were surveyed. The stream was 25-3^ feet 

 wide, and was flowing 18-20 c.f.s., at the upper terminus of the survey.
