The biggest catfish I have personally seen caught in Co came out of Chatfield Ponds accross from Kingfisher. A buddy of mine caught it, 12lbs, on chicken liver on a treble hook tied with sowing thread. A good way to rig up the pole is with a leader and a egg sinker behind a swivel. Loose line the pole and put a small peice of aluminum foil on the line. The foil is easy to see by lantern and by loose lining the pole the cat can take it without resistance.
Good luck ;D
