A second waterfall 18 feet high was reported a short distance 

 above the upper terminus of the survey/-. 



There are a number of electric pumps diverting water from the 

 lower section of the river. 



The lower 1^- miles of the stream is badly polluted by sewage 

 and sawmill vraste from the town of "i/illamina. 



The lower 2 miles is sluggish, with no salmon SDavming area. 

 The next S miles up to the falls contains sufficient spavming area 

 for at least 1^500 salmon » Above the falls the stream contains a 

 large amount of bedrock and little spavming area. No migratory fish 

 were seen or reported in Y/illamina Creek o 



Coast Creek , entering 3'2 miles upstream, had a flov;- of 3 c.f.s.^ 

 and a small additional amount of spavming area. 



The East Fork , entering 7 miles upstream, had a flov; of 4 c.f.s., 

 and was believed to be of little possible value to migratory fish. 



25M-(3)eo Rock Creek c — (October 4.^ 1945; Brewington and JohansonO 

 Enters the South Yamhill about 44 miles above the mouth. The stream 

 is about 9 miles long, of v/hich the lower 5 miles v/ere surveyed. It 

 was discharging 20 c»f»So^ but during the summer the discharge becomes 

 as low as 2 c.f .s . 



Three log jams, tvro of which were impassable, were located be- 

 tween 2 and 4 miles above the mouth . Three falls, 6, 6, and 9 feet 

 high, were located between 4 and 5 miles upstream, and all were at 

 least barriers at lov/ water. 



There v;as spavming area for 1,000 salmon below the first impassable 

 log jam, and S]3awning area for a feu hundred more fish could be made 

 available up to the falls. The stream area above the falls does not 

 warrant construction of fishT/ays. Wo migratory fish were seen or re- 

 ported.

 and Davis.) Enters the South Yamhill about 45 miles above the mouth. 

 The stream is 14 miles long, of wiiich the lower 4-| miles were surveyed o 

 The discharge was 7 c.f.s., and the v/ater temperature was 62°- 63° F. 

 Two beaver dams and a log jam near the upper terminus of the survey 

 were barriers to fish at low water. A series of 3 falls, each 3-4 feet 

 high, and with a log jam above them, located at the upper end of the 

 survey were at least barriers to fish at low water. 



There vras spavming area available for at least several hundred 

 salmon in the section surveyed » No migratory fish vrere seen or reported.
