Superfly, reading your reply, are you asking why the biologists on the Methow, Entiat, and Yakima Rivers do not move their surplus hatchery eggs to the Lewis River? If so, that can't be done. An endangered run of fish is determined by it's ESU (envirionmentaly signifcant Unit). If you move fish from one esu, say the Yakima, to another, say the Lewis, you are improving the Lewis' runs, but after years of reproduction, you are breeding out the Lewis River genes. So in the long run you are killing the Lewis River fish. To the sportsman that might not mean anything, but to the Environment and the Endangered spercies act, that means everything.
P.S. To all of you. Get off the wdfw's and other agency bios' asses. These are the people trying to make sure your grandchildren have fish.
