Here is a photo of the dock, looks like water but very shallow. Thanks for the replies, I did hire an excavator several years ago when we had a drought and the lake was low. The guy ran the track over a rock ledge got it stuck water in the cab. He couldn't swim and thought he was going to drown. He didn't but the nearly new Volvo excavator was not in as good of a shape. The lake is formed from a dammed up creek and it never dries out. The local water people are great and they have said that they want the sediment out as well. There used to be grants to restore these flood control structures, but not now. I own 133 acres around the lake so any kind of equipment is fine. I took the last amount of silt into a pasture out of the flood plane, let it dry, spread it out and seeded it into grass.
