I have always had my best luck catfishing on the river when it has rained or is raining and the water is on the rise...even if it's only slightly rising. The same is true on lakes, ponds, and strip pits. I have been fishing in the rain at night at a runoff that pours into a strip pit near here, and there was lightning hitting the ground...and even that wasnt enough to run me off from the action I was getting that night during that rainstorm. It was so good that you couldnt handle fishing with two rods because there was a fish on both rods everytime you threw out and the bait hit the bottom. I dont advise fishing during a lightning storm, but I did get away with it that time without getting charged.
