i don't know a whole lot bout catfishin' but it shouldn't be any different technique for bullhead or channel cats just diffent sized hooks. as far as the diffence between channels and bullheads, channels feed more by sight then other catfish, but i just use real stinky dough bait that way i have a shot at both. i've never fished lake kress, but if your fishing at night, try to fish around some sort of structure up in the shallows (pads, fallen trees, etc.) they cruise around there at night to feed. hope this helps.

if ya wanna know more bout catfishin' try this website there's tons of info catfish.com
