Cut shad is the best. It is the spawning time of year so your best bet may be close to the mouth of the major creeks (pecan and hickory on the west side). The water is warming up so fish are moving shallow. Again, anchor off in the mouth of a major creek on the right day and conditions and you catch them moving in and out. If you are looking for numbers of catfish, my advise is move into shallow water around tall grass and timber. Channels and smaller blues are crazy there. I was out there yesterday and had no problems finding them. There is what looks like a solid island north of the toll bridge and a little to the left but it is actually timber on the outside and standing grass and foliage. Cast at the edges and hold on to your pole.
Is it possible to do something your whole life and still be an ameteur?
