I've had consistent luck in 2-3 feet of water, right up against the last flooded brush facing submerged creek channels (lake-side of things). The channel cats can have a very light bite, I missed several this past Sunday to dull hooks (ik, no excuse) and not really recognizing the hits (bobber was too heavy).
Guess I got spoiled with lots of no-questions strikes a few weeks back.
Plug for Stubby's too. I've been real happy with his bait.
