When you approach the dam, look for the wall that separates the spillways from the turbines. Stop about 20 yards from that wall and try to position the boat on the edge of the current. Done right, you will get into an eddy that will slowly spin your boat 360 degrees. That is where I usually get my first bite. The bigger fish are closer to the anchor towers. The biggest ones I've seen are caught by the brave ones that fish the caves closest to the turbines.
