Chum Salaon 



Chum introductions have been infrequent. Willapa and Hoodsport stock were 

 brought to the Sateop Hatchery in the mid-1970 's (Stone, WDF, pers. coram. ) . 

 Chum production now depends entirely on natural production because hatchery 

 programs were not clearly successful (Stone 1989). 



Winter Run Steelhead 



Winter steelhead stocks from outside the Basin were historically used but 

 introductions decreased as hatcheries developed local brood stock sources. 

 Chambers Creek winter stock was released widely in the upper Chehalis 

 beginning in 1936 (WDW unpublished records). These records also show that 

 many releases were made from the Mossyrock Hatchery in the lower Columbia 

 drainage starting in 1943, that sporadic introductions from the Puyallup Ponds 

 were made starting in 1977, and that Bogachiel stock (which originated at 

 Chambers Creek) has been used since 1982. More recently, Cook Creek stock 

 from C/uinault National Fish Hatchery was released into the Humptulips. 



Native brood stock now supports programs that release smolts at Skookumchuck 

 Dam and Aberdeen Hatchery (Freymond 1989), and a local winter steelhead brood 

 stock is being developed at the Humptulips and Mayr Brothers hatcheries 

 (Huffman, Quinault Nation, pers. coram.). 



Summer Run Steelhead 



The first recorded summer steelhead release was made in 1926 by the WDG from 

 the Washougal Hatchery on the lower Columbia (Kugen, WDW, pers. coram.)- No 

 further introductions are on record until 1974, when summer steelhead from 

 Skamania Hatchery were released from Aberdeen Hatchery [WDW unpublished 



records). These records show that releases of lower Columns * :Y. became 



routine in the Wynoochee and HumptulipB rivers by 1980, when the WDW ADexoet: 

 Hatchery had developed a local population, derived from Skamania stock, in Van 

 Winkle Creek. 



Increasing pressure to develop a year-round sport fishery focused renewed 

 attention on summer steelhead introductions, because no local brood stock was 

 apparent (Harry Senn, pers. conn.). Harvest is managed exclusively for 

 hatchery production (Bob Paulsen, WDW, pers. ccenm. ) . Wild steelhead release 

 regulations are in effect June 30 through November 1 in all Chehalis Basin 

 streams to protect naturally produced summer steelhead. 



Other Salaonids 



In addition to these intensely managed species, cutthroat trout and resident 

 rainbow trout have been released from many non-Chehalis sources. However, sea- 

 run cutthroat trout hatchery programs have increasingly used local brood stock 

 since 1983; Jay Hunter (WDW, pers. comm. ) lists Skookumchuck, Elk, Johns, and 

 WishJcah rivers and Chenois Creek as brood stock sources.
