How do you fish for catfish in a lake?

Hey guys I was needing some help on fishing lakes. All I ever fish are rivers. I am going friday night and needing a little help. The lak has real deep holes, shallow ones, wood structures, and rock bluffs the enter the water. I am going to Greers Ferry. We are going to jug, but I was going to pole fish a little while we wait. I have fresh liver and perch. Thanx for any tips you'll can give.
