It flows through a narrow., uninhabited valley in a -vrooded mountain 

 areao The gradient and the banlcs are steep, there being many cas- 

 cades and lew falls over large boulders and bedrock. SpaTming area 

 occurs for the most part in small patches behind Vioulders and log 

 jams. The water temi)erature v/as 55°Fo Although this does not appear 

 to be a very good salmon stream, a fev^ chinooks have been reported 

 utilizing the spavming area in the past fevr years. At the time of 

 the survey rainbow trout fry and fingerlings were numerous^ 



25EE0 Middle Fork, Ifillamette River c- — (Lower 32 ..5 miles to 

 Lookout Point surveyed June 9~13s 193B by Hanavan, Parkhurst, Morton. 

 Wilding, and langtonj next 35 miles surveyed August 28 - September 11, 

 1937 by Hanavan, Baltz,o. Kolloen, and Lobell,) Joins the Coast Fork 

 to form the main Wil].amette River 4- miles above the City of Eugene ^ 

 Oregon, or approximately 189 miles above the nouth. The stream ex- 

 tends for about 77 miles to its source in Opal, Temanogas , and Indigo 

 Lakes, high in the Cascade Range. UoS<,G.S. records show a maximum 

 flow of 55^.,100 Cof.Soc on February 21, 1927. and a minimum flow of 

 450 c.f.So, on several occasions from September to December at the 

 gaging station 30 miles above the mouth. Severe floods are frequent 

 in the lower section of the -vTatershed, The gradient is moderate ex- 

 cept for the head-yraters. Th.e water temperature was 4S-59'^F. 



The stream flows tnrough a valley 100 ^/ards to 3/U mile wide , 

 bounded by high wooded ridges. There is an extensive flood plain 

 area in the lower section where during low water periods there may 

 be as many as five different channels . There are also some multiple 

 channels in the upper section of the stream^, due to the formation of 

 log and debris jara^s. Dense grovrths of viilloif, alder, and maple,, with 

 some conifers occur along the margins of the stream., and stands of 

 pine dominate the upper drainage area. Farming is practiced only in 

 the lower portion, and is mainly dairy pasturage. There is some 

 domestic pollution in the vicinity of Westfir and Oakridge.-, Oregon. 

 Some log jams vrere found in the upper 10 miles surveyed o but all were 

 considered passable. 



The Springfield diversion canal,, located 2|- miles above the mouthy 

 requires further study. 



The *-^regon Fish Commission retains salmon racks in the river from 

 Ifey to October at a point about 2 miles above Oakridge ^ and approxi- 

 mately 41 miles above the noutho The eggs taken here are propagated 

 at the tiatchery on Salmon Creek. 



The Oregon Fish Commission (Research Briefs Vol,, 1, No. 2.) lists 

 the principal sjavming area as being from the Westfir bridge (just be- 

 low the North Fork^ river mile 3^) downstream to Duvall Creek driver 

 mile 31) » However,, in 1937 when tne hatchery racks had washed out_,
