Horton Scarberry, from S&B Manufacturing, North Baltimore, assembles a floating dock near a shelter house along Grand Lake's East Bank in Auglaize County on Tuesday. Grand Lake St. Marys State Park received a grant to install four floating courtesy docks on two rock piers. The docks can be used by boaters to get out of storms, to use nearby restrooms or to have a picnic, said assistant park manager Brian Miller. People also can fish off the docks as long as they give boaters the right of way. Boats may park at the docks for no more than an hour, Miller said.
