Lake Gaston Catfishing

My friends and I are up from Durham and we heard this lake rips big blue cats. Well, we've tried alot and been skunked 3 nights running.

We got hot dogs, all sorts of bait that smells putrid, crawfish plastics, chumming with dog food throughout the day. We are dock fishing with lights at night. Trying to see if anyone has tips on what is hitting right now or how to get something? Would love some help.
