Hello, I fish a medium sized river with both flats and channels, and maybe a few blues. The place that I fish is a sandbar about 100 yards away from a wing dam and a regular dam. I just started fishing for cats and have only caught channels. I think that it is fairly shallow on the flat with the only deep holes being around the dam, I was wondering if this would be a place that flatties would roam to at night looking for food. There is not really any structure around the flat besides the dams, and a few rocks. There are a lot of little minnows that fill up the sandbar at night and I have had some luck with channels. Also, if there are a lot of turtles in a spot does that mean there won't be a lot of catfish? Thanks from a newbie just learning.
