There are other runs in the Puget Sound that have been doing well, SEARUN CUTTHROAT and WILD SUMMER RUNS. They live in the streams a similar time frame to winter runs. Yet through MANAGEMENT (thanks Curt) they have come back, the cutts in large numbers.
Also I understand in the Strait of Georgia there are streams with high quality habitat and zero harvest that the wild winter run steelhead numbers have dropped 10 fold. What’s going on?
Why are wild summer run numbers increasing in the PS basin?
My opinion of the mass of society impact on the Snohomish system is exaggerated. Running the Snohomish and Sky from Everett to the High Bridge the obvious run off impacts appear small. The Everett area is industrialized, but it has been for 100 years. We had big runs of wild fish here when the saw mills were dumping without regulations. Logging practices were nonexistent until the 1980’s. It will be argued how wrong I am, but, the incremental changes on this system appear slight.
My point is the problem of local habitat, past harvest practices or hatchery practices may not be the major issues. Something is going on to our fish else where that isn't effecting chums, pinks, searuns and summer runs.
