Glad to see anglers get upset enough to do something about the situation. Rvrguy has lots of history regarding this issue and many more in the Chehalis Basin, he is an excellent ally and source for information. The intake on Stevens Creek is a no-brainer, I first heard about it in 1997, and it was a recommendation of the HSRG panel as well. Long, long overdue and a common sense fix. (maybe that's why it's not been done?) Have heard of hatchery stray rates as high as 70% on the spawning grounds for many many years. Remember, this is your agency and your resource. You pay for it, and you have a right to direct its management. Go above WDFW to your legislatures and let 'gravity' to the rest.
