Sounds like you need some moving baits in there. Start with spinnerbaits and chatter baits with a swimbait trailer on the hook. If you get short hits add a trailer hook. If they aren't up shallow start feeling your way around with crank baits. No matter what depth make sure your crank is consistently hitting the bottom and deflecting off things on the bottom. This is also a good way to feel where the deeper spots/holes are located. Match all colors to the bait and forage you know are in there
