Okie, when we did that show we set up in the deepest part of the channel and put the lights around the thermocline. When the water gets to 85 degrees the fish will go to the oxygen. The other reason I picked that spot was the clarity of the water. When night fishing the fishing is better in clearer water, not saying you can't catch them in murky water you can. But the same rules apply in clear water fish are deeper, murky water the fish are shallower. EB
