Late july and august is usually a good months to catch spots that are suspended.
I have never caught a crappie out on the lake. I use to work at grove marina and there around the store is the only place a I have been able to catch any crappie. The ones I have caught and seen caught have been decent size. But the better times there was in the spring. Bluegill are fairly easy to catch but no size. Trout fishing at night under lights is pretty good.
