I've had good luck sometimes with redears fishing a redworm or nice chunk of nightcrawler threaded on a light wire hook and fished drop shot style 8"-10" off the bottom with a medium-sized splitshot for the weight on the bottom. I'll cast it into the area and either leave it sitting (with the line tight) or will very slowly reel or drag it across the bottom until I get a bite. I've caught a few nice ones at a local spot this way. Might be worth giving it a shot.
