I catch most of my flatheads in probably between 8 and 12 feet of water during most of the warm weather. In the cool down in the fall, there a couple of 20 to 30 foot holes (deepest in the area) that produce well for wintering or at least cold water staging fish. My question is this - I am figuring that they are at their shallowest in the spring. When things get good and hot in mid summer, do they tend to go deeper? I'm especially interested to hear what the other southerners have to say. You Minnesota/Wisconsin types never ever see hot water. By the way, my SC rivers are around 77 degrees now and will be in the high 80's in another couple of months.
