I have done more catfishing there than anywhere else, and I can say my night-fishing SUCKS there. I just cant find them.
I believe, but have not proven it to myself that the cats are shallow, on the south side of the channel, north of the discharge. I will attempt it soon, and try depths in the 10-18 foot range, maybe even use floats, or better yet, ballons with glow sticks inside of them.
