Might not have many guys on here that fish Monticello. I know I have seen very few reports from that lake. I have only fished it 3 or 4 times myself, so I can't offer much help. We always seem to end up with several catfish, whether we were fishing for them or not.
I have a friend who fishes there quite a bit, but he is not a member here. He trolls exclusively for huge catfish using Buck Spoonplugs. I did not even know they still made them, but he swears by them. He has caught some huge cats and bass at Monticello doing that.
