There was a gra\^l pit and irasher 7i±th a drag line taking gravel 

 from the stream bed at- a point 2^- miles above the noutho log jaras^ 

 impassable at low water ^ were fcund 11^ miles upstream, Ipg miles up- 

 stream, and 17 miles upstream. Slightly over 13 miles upstream there 

 was a water wheel, impassable at 1oy< 7/ater, operating a small irriga- 

 tion pump. Finally^ 17^ miles upstream or just below the nouth of the 

 South Fork there is a 12 foot high lumber mill dam. This dam is pro- 

 vided with an efficient fishv/ay, and salmon have been observed going 

 through it. There are several other small log jams and old low dams, 

 none of which are barriers to fish. Tliere are also a number of small 

 irrigation divers ions ^ most of them supplied by screened pumps o 



A small run of spring chinook salmon is able to pass most of the 

 stream obstructions at spring high water, and several of them were 

 observed spavming in the middle section of the stream. Although not 

 observed, a fevf silver salmon and steelhead trout also have been re- 

 portedo There is suitable spavming area for at least 4.^000 salmon in 

 the lower 11 miles, belov/ the first bad log jam, and S'Tavming area for 

 at least 1,500-2,000 additional fish above. The best spawning areas 

 occur in the middle section of the stream. This stream can support a 

 much larger salmon population^ particularly v^ith needed stream improve- 

 ments and restocking. Resident trout vrere observed in the upper section. 



Clear Creek , Iler Creek , Glenwood Creek , and the Soutn Fork .— 

 All had flov;s of 2-4 c.f.s., and maj^ have some value to fish. 



25D-(12). Sco^gins Creek .— (September 17, 194-05 Frey and Zimmer. 

 September 11-12, 19455 ^navan, Rucker, and Silliman.) Enters the 

 Tualatin River approximately 53 miles above the nouth. The stream is 

 about 18 miles long, of v^hich 4^ miles were surveyed. The recorded 

 flow near the mouth ranges from slightly more than 1 c.f.s., to more 

 than 1,600 c.f.s., with the mean flovf for the v/ater year 1944-45 being 

 102 c.f .s.,(u.S.G.S. records). This great fluctuation decreases any 

 possible value the stream might have for fish production. 



A dam 4 feet high located about 5-| miles above the mouth is a 

 barrier to fish at low water. Another dam 5 feet high located about 

 7 miles above the mouth is also a barrier at low water. Three log 

 jams in the upper section should be removed. 



There was sufficient spawning area below the loT/er dam at the 

 time of the 1945 survey to accommodate at least 600 salmon;; and suf- 

 ficient spawning area above this obstruction to accommodate a somev^hat 

 greater number, liovrever^ at times of lovf flov;- conditions a large part 

 of this spavming area is exposed. 



It vras reported by several local residents that a few chinook 

 and silver salmon enter the stream during the late fall rains. A small 

 number of steelhead trout also vrere reported, and some salmon finger- 

 lings were observed. The stream is regarded as being of only slight value as 

 salmon producer.
