Joey,
By far, the majority of catfish I've caught over the years have been caught after sundown, or during heavy overcast. That goes for river channel cats as well as my pond channel cats. Same goes for bullheads. I've always felt that the cats I've caught during the day were accidents.
One of the other things about catfish, especially channel cats and flathead cats is indecision and caution. They don't attack like bass or pike. To be successful, you've got to let catfish, particularly larger catfish, take the bait and run for a number of yards before trying to set the hook. Even then, I've lost a lot of them by pulling on the line too soon.
So . . . if the evening is calm, give it a try starting at sundown.
Good luck,
Ken
