I found a deep hole(45ft) in a narrow cut between two islands on the Mississippi. My question is how far from the hole will the catfish go at night and if up,down or across the current would be best. There are shallow flats(7-10ft)all four ways. Been fishing a long time but just started making an effort the go for the big one. Just found this site this spring and you guys have more than doubled the average fish for me. Thanks for you help.
