I planned to build a security fence from the mill to the walkway. This way I could walk from the door (I restored) to the walkway and rake the trash rack. I was concerned about folks walking around on the walkway and the fence would keep them off. I had put up a sign “DANGER – STAY BACK 30 FEET – DANGER” This seemed to keep folks off. So, I just added more boards instead of the fence. This will allow more water into the mill. The fence would restrict some of the water flow.
