Leaning towards giving a sand point well a try. Found a hand pump and shallow well pump I can use for free to give it a whirl. Thinking about going 4' off my floating dock and mounting the pump to the dock with a flexible hose connected to the sand point. Dig a test hole at that location tonight and hit water at 5'. Little bit different soil there though, it was dry all the way down, no mud to dig though and hit about 3' of sand /clay mixture. I'll drive my sand point down another 5' and see what kind of water I get there before going deeper.
