In response to the question about what they do with the fish at the fishtrap below the dam(plug puller?), I know some get trucked to the lake aberdeen hatchery for egg take. Whether this includes wild fish I am not 100% sure.

The Wynoochee uses 2 stocks for winter hatchery production:

1) Van Winkle Cr. stock. These are fish that
return directly to the hatchery at Lake
Aberdeen.

2) Wynoochee R. stock. These are the fish
collected at the trap up by the dam and then
trucked to the Lake Aberdeen hatchery.

At least this is how it was explained to me by a WDFW friend a year or two ago. I also don't believe the dept. holds any illusion that smolt passage works at the dam hence, the trucking of adults to the hatchery for egg take.
