the skookumchuck uses local stock....and they seem to get good returns...but as far as the success rate of those guys spawning in the wild i'd have to say is near zero....i rarely ever see any wild smolts and haven't caught a wild/feral fish there in years...lots of hatchery fish though...but the wild/feral fish i have caught there stand out in memory for their fight and strength more than any of the hatchery guys..
i'm not anti-hatchery having worked in and around them for many years...but i know they are no panacea even when run well...

the Kalama Research Team has been releasing smolts from 'wild' parents for a few years now and they should soon be getting to the point where the spawning success etc. of those guys
can be pinned down....it'll be interesting to see...
