You should definitely be around some kind of cover....docks, brushpiles, etc. with some deep water nearby. Fish very slowly. If you know you are over a brushpile, drop your bait to hang right over it and keep it fairly still. Raise it very slowly and see if they are holding at a certain depth. Try different things....bobbers, minnows, big baits, as well as different locations....creeks, main channel docks, etc

good luck.
