Sorry, but I'm a little confused. By "facing them" do you mean facing up river and looking at the hydros?
I know of the rock ledge that comes out of the Kentucky side of the river at the hydros where the concrete tower is on the Ky shore. I'm also aware of the "reef" or "shallow water" area where the lower dam and the hydros meet and form an "L"
Where were these boats hung up?? I've seen a couple of unaware boaters get hung up on the rock ledge that comes out of the Ky side of the river by that concrete tower.
