Last Summer I did really good trolling crankbaits along the face of the Dam in about 14 FOW running the baits about 12ft deep. I caught fish anywhere on the face of the Dam but my best luck was towards the south end just outside the mouth of those little coves there. I you park by the species list sign and walk straight down to the water you could set up a slip bobber rig with a minnow and set your bobber stop at about 10ft and give it a good cast out you can contact those fish. The 14 FOW I was trolling in was pretty close to the bank so a good cast out should reach them, and I actually had better luck in the afternoon than in the morning.
