Hey Onelove,
I caught the cat while drifting a large chunk of chicken liver. I was using a 2/0 Kahle hook and about a 1/4 ounce of split shot about 2 feet above the hook. Cast it out and let it sink and walk along the bank as it drifts. I marked a bunch of fish on the bottom there but I guess the cold still has the majority tight lipped. Were there any saftey ladders around where you got snagged. Sometimes there is a huge belly in the anchor cables to those things. Don't give up on the linesides, still nipple freezing cold water in there.
