This is the highest concentration of channels cats in the world. They are everywhere, like annoying parasite. They bite lures, and will eat anything they see. One time i decided to just catch them all so they stop bothering me. I was fishing under my boat, anchored. I put a small hook and started keeping them. Got about 30 and got tired. Bite never slowed down. There must be millions of them there.
But with all of that said, they will prefer normal channel spots. If you have a boat, find a hole, and anchor not inside the hole, but on the edge of the hole. If from the bank, go find a tree or some point or some structure or sudden change of depth... stuff like that. South side is deeper and easier to access them. On north side you will need to cast kind of far because it is really shallow by the ramp.
