try the columbia near below wanapum or potholes reservoir, dont know what the walleye are biting on now but a coupla years ago it was all about vertically jigging blade baits, or trolling cranks or double whammys with crawlers or leaches, if you go to potholes go into mardon and ask and they should be able to let ya know what theyve been caught on and what parts of the lake to fish
