I havent caught crappie out of the big oxbow lake behind the power plant at dutch gap but the hot water discharge keeps it much warmer in there. Especially when they have both stacks burning. Last time I was down that way a fella told me he caught a 2lb crappie drop shotting for bass on his first drop on a barge. Might try down there. I have had some decent bass days close to the city with crankbaits and pitching jigs to pilings but it is definitely not loaded with resident fish up there.
