R. and tributary. 



Small run, but well suited for spawning. 

 Run blocked by dam at km. 24. 



Practically continuous spawning riffles 

 in available section. 



A few chum salmon reported in North 

 Fork. 



Small run reported in suitable areas to 

 a dam 8 km. up. 



Grays R. Hatchery of W.D.F.. operated 

 since I960, supplements production. 

 Upper portion was blocked by falls but 

 is now available. Good survival of 

 eggs in Crazy Johnson Cr., concentrated 

 spawning in spring-fed area. 



Big Creek Hatchery of O.F.C. blocks 

 run at km. 5. Hatchery rears part 

 of run. 



Small stream, has little spawning area. 

 Much of streambed is bedrock or large 

 rubble. 



Small stream, extent used by chum 

 salmon unknown. 



Fair-sized run enters to spawn. Elokomin 

 Fish Hatchery (W.D.F.) rears part of 

 run. 



Spawning gravel adequate for several 

 thousand salmon in 13-km. section above 

 tidewater. Spawning area was added 

 when Clatskanie Falls was made passable 

 in 1950. Beaver Cr. has about 5 km. 

 of spawning area, above tidewater to 

 Beaver Cr. Falls. 



in I 



ower reaches. 



Supports good 



Abernathy National Fish Hatchery sup- 

 plements production ; good spawning 

 areas. 



Many good spawning areas; good run. 



Spawning limited by falls, high portion 

 of large rubble, and bedrock. Only a 

 few chum salmon use stream. 



Chum salmon pass through lower tribu- 

 tary. Former area inundated by reservoir. 



Small run uses lower part of this tribu- 

 tary. A few chum salmon may spawn 

 in lower Ostrander, Arkansas, Salmon, 

 Olequa. and La Camas Creeks, and 

 Toutle R. but none observed in recent 

 years. 



A few chum salmon, reported in past, 

 but no established run believed in stream 

 at present. 



Small run spawns in this stream. Some 

 reared for a period at the Lewis R, 

 Hatchery (W.D.F.), but none in recent 

 years. 



Used by a few more chum than the 

 main Lewis R. Good spawning area, 

 designated on map. 



Formerly had a much larger run than 

 now, Streamflow reduced because water 

 supply taken by town of St. Helens. 



Small run use this small stream. Sum- 

 mer flows become rather low, but are 

 high when chum salmon use the stream. 



A fair run of chum salmon enters this 

 tributary during fall when sufficient 

 water is present to dilute effluents from 

 the Camas Paper Mill.
