Spring Chinook Salmon 



Spring Chinook have never been successfully propagated in a Chehalis Basin 

 hatchery. Small-scale attempts to culture Skookumchuck spring Chinook were 

 made in the late 1970s, with only limited success because brood stock was 

 difficult to collect and Burvival was poor. In 1977 and 1978, Cowlitz spring 

 Chinook were introduced into the Wynoochee (Stone, WDF, pers. conn.). QFiD 

 personnel have intermittently found Chinook with spring timing in the 

 Wynoochee since 1987 (Chitwood, QFiD, pers. coram.). Now, with increasing 

 emphasis on developing a year-round sport fishery, some parties propose 

 restoring Wynoochee spring Chinook with upper Chehalis stock (Dave Hamilton, 

 CBFTF, pers. coram.). 



Fall Chinook Salmon 



Fall Chinook hatchery brood stock was transferred from the Kalama in the 

 1890s, later from Green River via the Deschutes, then from the Elk and Trask 

 Rivers of coastal Oregon in the early 1970 's, and most recently, from the 

 Willapa Hatchery in the late 1970 *s (Johnson and Longwill 1991). Most non- 

 native introductions have been made to the Sat sop and, for this reason, WDF 

 does not now allow Satsop Hatchery fall Chinook releases outside the Satsop 

 drainage (Rick Brix, WDF, pers. coram. ) . 



Co ho Salmon 



Coho hatchery brood stock have also come from numerous sources, beginning with 

 introductions from the Kalama in the 1890s (Stone, WDF, pers., coram. ) • Fr Y 

 releases from the Willapa Hatchery to the upper Chehalis have been frequent 

 throughout the history of hatchery production (Stone, WDF, pers. coram. ) . 

 Quileute summer coho were also used on one occasion. The latest import was 

 Hoodsport stock in the early 1980s. Dnlike fall Chinook, coho introductions 

 have been spread throughout the Basin, so no efforts are now made to confine 

 current releases to one area (Brix, WDF, pers. coram.).
