Tie off to the 1097 bridge, and bait the hole with some range cubes from a ranch store, or maybe some scattered corn or something else that stinks but doesn't make a full meal.
you can also go up one of the creeks on the upper side of the lake, and stay in the main creek channel until you near some of the stump fields and do the same thing in the stump fields adjacent to the creek channels.
Either way, any stinky catfish type bait will work. conroe channel cats are easy. Peeled shrimp, chicken livers, whatever..it will work.
