The lower 9 miles are in the gently rolling Willamette Valley 

 where the stream bed is composed largely of mud and silt. Above this 

 point the gradient gradually increases and the stream bed is composed 

 largely of bedr-ock and boulders. 



The 8 foot high Lima Dam. located 9^ miles upstream is a barrier 

 .to migratory fish, as is also the similar Hartman Dam located 10^ 

 miles upstream. 



The Sootts Mills power dam, located 11 miles upstream is 4 feet 

 high J but is built on the crest of a 14. foot natural falls, and is 

 impassable to fish.

 supplies water to the town of Silverton through a screened diversion. 

 A poor fish ladder is present. 



There is spavming area available for at least 6,000 salmon in 

 the section surveyed.. 



Approximately 50 spring chinooks were held up at the dam until 

 the survey crew removed debris from the fish ladder. Approximately 

 200 Chinook s pawners were observed in the next 6 miles above the dam. 



Loggir;g operations being carried on along the stream in the next 

 3 miles were fomid to be obstructing the stream in several places .
