I look for water 30+ deep this time of year. Like others said, if you see a cluster of boats dropping baits straight down, go join them. There are plenty of fish to go around just be courteous and don't get to close to someone. Put a 3/4oz egg sinker on your line, and then tie on a swivel. Below that tie on a crappie jig or minnow hook about 8 inches below the swivel/weight. Drop it straight down, when it hits bottom, crank your reel 2-3 times and wait. Can't go wrong with that technique this time of year.
