In addition to all the good suggestions above, Sprague Lake over between Ritzville and Spokane has a lot of big crappies, as well as monster bluegills, perch, trout, channel cats and who knows what all else. With the crappies, the bite is normally just before dark, continuing for a couple hours after dark. The east/northeast end of the lake in about 13-17 feet of water has always worked for me. Use mini- jigs tipped with worm or maggots.
