Catfish are really biting NOW on Lewisville. Blues and channels are in the shallows with the flooded bushes. Find any wind blown pocket with 2-4ft of flooded bushes. Throw cut shad about a 1-2 ft under a cork and you will catch plenty. If you can't catch shad any bait should work-shrimp, earthworms, maybe punch bait although that's more channel cat food. The first couple of main lake pockets on either side of the BIG main lake point (don't know the name of the point) but it's the main point coming out of Tower Bay going North towards the rest of the lake.
Are you talking about the main lake point you idle by as you're leaving Tower Bay (you idle between the point and the marina tire reef)? Not sure if that one has a name. From there, the pocket on the north shore would have a south wind blowing into them. There are several pockets along that shore between the big main lake point I-35 bridge and the big main lake point that you would turn left at to head north towards the old dam (there is a name for that point I just can't think of it now).
