The "private" hatchery you might be referring to is/was in Vesta on the N. River. Kings and Silvers were planted there for years with large returns during the '90s. So much for the theory behind salvaging the last "pure" run of Chinook in WB by squeezing anglers out of the area north of marker 13.

A local fishing club used to plant summer runs in the S. Fork. Funny that WDFW reports all steelhead plantings but apparently doesn't do the same with salmon.
