I was there in October trying to catch channel cat, which were slow. We saw a couple of teenagers in a jon boat wearing out the Tilapia on jigs. We started catching on Roadrunner jigs. We caught the larger fish fishing the bank and trees at the boat ramp. There is a creek above the intake where we caught the majority, but they are all over the lake.
I have heard that some people use lettuce, as they are stocked to eat excess vegetation.
