Hey Bill...Silver lake should fit the bill! The Crappie should be goin nuts by then and there is the park right down from Streaters resort where you can get lots of bobber areas plus by the Cemetary hole right off the roadway! The three campgrounds should work or the motels are right close too!

Bill,
Since I E Washington info, I would suggest Mardons, great access and someone is always catching something.  Also, there is a nice campground a littel further east across the dam on Warden Lake.  Real nice place, Rob Maglio can attest as well.  More trout fishing there.  Also, the park at Scootney Reservoir has a ton of bank access and holds all of what you may be looking for.  Just my two cents.

The places Gotfive mentioned are just what you want. Nice campgrounds with the necessities and tons of fishing around that area. What I would suggest however are the many seep lakes around there. Warden happens to be one and I've seen people catch tons of bullheads. I even tried it one night. You can jump from lake to lake until you find one you like.

You can also dry camp back in the seep lakes if you want the real rugged outdoor experience. We used to do this in high school. Soda Lake, Upper and Lower Goose, Heart, Corral and many others are all good. I have had real good luck on the dam side of Soda. There is a gravel road that runs on the top with a launch at one end. You can fish from anywhere around there or hike the edges. Smallmouth, Walleye and crappie bit for us this last Spring and Summer.
