GH & Willapa are examples of how to manage harvest and not to manage harvest. Willapa in the past and one could argue today is an example of how NOT to manage harvest. It was and is managed for commercial harvest right down to rearing the wrong fish in the wrong hatcheries.

Grays Harbor was and is managed for wild production which means hatchery fish are a bonus. Back some years this resulted in substantial hatchery returns which motivated both commercial and recs screaming more harvest on the "surplus". So the agency just reduced hatchery production because the Chehalis is managed for the natural returns. Now we have a much diminished hatchery production and the returns are more or less managed exactly the same.

All that said in my view it is the use of the aggregate of the tributary returns to enable harvest in the lower river Chehalis that poses the greatest risk for the fish in the individual tributaries. When you have the Satsop at 40% to 50% of escapement in recent years ( other tribs did worse ) and still harvest I think some priorities are miss placed.
