Hatchery blocked 

 upper portion. 



Small stream, has small quantity of 1, 38 

 suitable spawning area. 



First 5 km. above tidewater has best 29 

 gravel. Supports smaJl run. 



Series of spawning riffles. Most of pro- 29 

 duction is from plants of juveniles above 

 falls. 



Klaskanine Hatchery (O.F.C.) on North 29 

 Fork rears most of large run. Fish in 

 excess of hatchery needs are released to 

 spawn. 



Small stream, supplies water for Astoria, 29 

 Oreg. Falls 5 km. up is low water 

 barrier. 



Grays River Hatchery operated by 1, 38 

 W.D.F. (Washington Department of 

 Fisheries) since 1960, supplements pro- 

 duction. Falls recently made passable 

 to salmon. 



O.F.C. operates a permanent rack and 29 

 trap structure. 5 km. up to take salmon 

 for Big Creek Hatchery. Salmon in 

 excess of hatchery capacity are released, 

 and much of area above is used by 

 spawners. 



Prevalence of large rubble— little spawn- 29 

 ing area. 



Small stream, supports small run. 1, 



Elokomin Hatchery (W.D.F.) rears part 

 of run. 



Has small run. Falls, rapids, and log- 

 jams made passable, increasing spawning 



area. 



Excellent spawning areas. Abernathy 

 Falls laddered in 1951. Abernathy Fish 

 Hatchery rears part of run. 



Good spawning areas up to falls. 



Cowlitz system is largest producer of 

 coho salmon in Columbia Basin. Many 

 kilometers of excellent spawning and 

 rearing areas. Large percentage of run 

 formerly went past Mayfield and Mossy 

 Rock Dams to spawn. Most o( run will 

 be reared in a hatchery; fish in surplus 

 of rearing capacity of hatcheries will be 

 released for spawning in areas above 

 dams. 



Fishway at Coweeman Falls allows fish 1. 38 

 to use midriver areas- Considered to 

 be a good coho salmon stream. 



Removal of beaver dams, logjams has 1, 38 

 increased spawning area in this small 

 tributary. 



Arkansas Cr. is formed 3 km. up by 1, 38 

 union of North and South Forks. 

 Spawning in two forks; lower portions 

 are used as rearing areas. 



Large tributary, good producer, many 1 , 38 

 excellent spawning and rearing areas. 

 Its small tributaries have good areas. 



Many kilometers of fine holding pools 1. 38 

 and spawning riffles; many small trib- 

 utaries nearly all too small or too steep 

 for salmon. 



Fish spawn in fair numbers below Toutle I, 38 

 R. Hatchery (W.D.F.) rack. Rest 

 reared in hatchery.
