First I would concentrate on steep channel bends that come close to shore, or bluff walls. Try spoons, blade baits(silver buddy), drop shot, and jigs.
I wouldn't overlook that stump field either. I'd try a jig, a jerkbait, or a lipless crank. With the jerkbait, start off with LONG pauses between jerks, but if you don't get bit, try different retrieves. Also with the lipless crank, fish it very slowly, almost like a worm. Try to bump it off of those stups without hanging up. Good luck man!
