I dont have as much experience of catching winter time Channel cats in a pond but catch hundreds of them in the river in the winter time, they will be really sluggish and slow and on the bottom, doubt that you will have much luck on a bobber, In my pond, even in the fall when they were eating feed, I would catch a few around the feeder but mostly by fishing the bottom. in a pond there will be a therm o cline or in other words, warmer water at deeper depths, thats where they like to hang out. even on a river with moving water they will congregate in the deeper holes. on stink bait, the worse the better, rotten chicken livers or rotten cut carp.
