Havnt fished like that in a few years, but we used to anchor off of a point or wall where the creek channel turned in close to the bank, and float our lights till the baitfish started circling in the light. We usually had minnows, and would let them down to the bottom and start reeling them up very slowly untill we located the depth the fish were at. Sometimes the action would be fast and then would taper off, but as long as the baitfish are there the fish will usually come. Good luck.
