the flatheads are everywhere now, I was catching big ones as far as the gap last year. it's pretty easy, hook a 4-5" (or bigger) sunny (or anything legal thats alive) with a 6/o (or bigger) circle and a few ounces of weight on a fish finder rig, cast it out 20-30 feet and wait. go at night. i prefer slower but moving water. i dont think the spot even matters all that much, at night they are on the move and travel long distances in search of food. my biggest one last year was in 2' of water in a spot i thought was far from ideal because the group i was with weren't fishing and just wanted to do the camping thing.
there are probably many ways of doing it better than what i do, this is just my method.
