The water at Alton is Kinda strange right now. Above the dam the water is the lowest I have ever seen it. At the Alton Marina both docks are totally out of the water the sand (MUD) bar is exposed and most of the bridge pylons are out of the water. Upstream at Piasa Creek both of the docks are sitting on land and lots of dead fish. You could probably launch with a four wheel drive, but your rig is probably gonna be covered in mud. If you ever wondered what strange water looked like it is worth a look.
