I think that this subject was covered before here. There was a lake in Snohomish Co. That was planted a few years ago. I think it was called Big Greider Lake. East of Spada Lake. Also I think that Stacie Kelsey she works for Dept of F&W. had some input. Thats all I have but if you have a Washington State Fishing Guide. That usually has a lot of info in it. Jim S.
