Back to the Cowletz. It would seem to me that if you are going to fill a river with Hatchery fish "Petting zoo" The Cow might be the river to do it in. With nothing but wild fish making it above barrier dam. And then recycle all fin clipped fish. Lots of guides work on that river along with many gear fisherman. What ever strays that wonder in to the other tribs. could also be harvested. It is my understanding though that the agreement with Tacoma power states something like they are committed to 650,000 lbs of fish. That includes Chinook,Coho, Steelhead, cutthroat.
