Get some bottom bouncing rigs. You'll probably have to buy them online because I think it's kind of a yankee thing. Troll around the islands and you will catch em. Only bad thing is you will catch about 20-30 Kentuckies for every walleye. Drop straight down to the bottom and put the boat in gear. You will feel the wire on the weight tapping the bottom. We also used to throw crankbaits on shallow points on cloudy days or early and late.
