Lower part of main 

 stem and area above 

 Condit Dam (3 km. 

 above mouth). 



Main Santiam used as passageway and 29, 40 

 possible rearing area during cooler 

 months. 



Steelhead trout collected at Minto Racks 29. 40 

 averaged 1,000 adults in 1952-59. Eggs 

 taken to Santiam Hatchery (O.F.C.). 

 Little Norih Santiam has run which 

 spawns naturally. 



Important producer; has good spawning 29, 40 

 and rearing areas. 



Has many excellent spawning areas. 29, 40 

 Green Peter, and Foster Dams, may re- 

 duce value of this tributary In addition 

 to loss of spawning area. Some reared 

 at Mrddle Santiam Hatchery (O.F.C.); 

 the remainder spawn naturally. 



Finley Dam blocked upper river for 100 29, 40 

 years; washed out in 1949. Best 

 spawning gravel in upper area. De- 

 pleted run not built up yet. 



Steelhead trout in small numbers after 29, 40 

 runs introduced in 1956. Apparently, 

 no prior use of McKenzie by species. 



Although it seems likely that this spe- 29, 40 

 cies spawned In the Middle Fork and the 

 OG.C. believes they did. the OF.C. 

 offers evidence that they did not occur 

 naturally. An egg-taking and eyeing 

 station established in 191 1 would have 

 trapped any steelhead trout had they 

 been present. Stock introductions were 

 made in the 1950's and adults returned 

 to Dexter Holding Pond since 1957; 

 others spawn in the areas designated. 

 Fish trapped at Dexter Dam for rearing 

 at Willamette Hatchery (O.F.C.). 



Many obstructions were made passable 1, 35 

 in this system. One of the better 

 "steelhead fishing streams" in south- 

 western Washington. Skamania Hatch- 

 ery of W.D.G, (Washington Department 

 of Game) rears part of run. 



O.G.C. stocks stream with young steel- 29 

 head trout. Upper Sandy has good 

 spawning areas. Provides a good sport 

 fishery throughout. 



Scattered spa.wning areas below dams 29 

 used by small run. 



A good share of run to main Sandy R. 29 

 spawns in this tributary. 



Small streams used by small run up to I, 35 

 impassible falls, 6.4 km. above mouth. 



Small number of steelhead trout use this 29 

 stream to falls. 



Impassable falls, 1.6 km, above mouth, 29 

 limits migration. Small run. 



l'pper good spawning areas open again I, 35 

 after being blocked for many years by 

 small lumber dam 22 km. up. Dam 

 removed in 1947. Stream noted for sum- 

 mer steelhead sport fishing. Species able 

 to ascend Shipperd Falls during high 

 water, but fish ladder made ascent easier. 

 Other stream improvements. 



A few steelhead trout spawn In small I, 35 

 area available. Two falls block upper 

 area. 



Steelhead trout known to have migrated 

 as far as Trout L. Condit Dam, con- 

 structed In 1912, had a fishway; some 

 steelhead trout were reported to have 

 ascended. Ladder removed in a few 

 years as not successful In passing salmon. 

 In 1937 Bonneville Dam flooded lower 

 part of stream.
