Their is some really good trout fishing in your area. The one thing the WDFW does right over there is plant fish. Jumbows, catchables, and fingerlings that grow wild. I have a retired friend that lives in Spokane and is dialed in fly fishing for them. He fishes all over 3-4 times a week. I spent more time this spring over there because of the lower Columbia Springer closure and glad I did. 2-10# bows are a blast on a 3 and 5 wt, and on a good day you can have 30+ fish day catch and release. Pontoon boats are a huge advantage. Most lakes have easy access with few crowds. Take advantage of it! The only thing that you have to work around are the heavy wind days. But then you need a break anyway.
