I can't say if they were catfish or not but about 1/3/-1/2 the way out into the channel on the inside horseshoe bend had so many fish stacked top to bottom that my whole screen was almost black from 8 ft down to 40+ ft. I was just waiting and waiting and nothing happened. Biggest group of fish I've ever seen on my screen. There were 2 other boats fishing there so it seems like it could be a hot spot
