Abstract:
1. A method of dredging a pond, comprising: positioning on land at least three winching stations spaced at spaced intervals around a perimeter of a pond, wherein each winching station comprises a winch and a length of cable; connecting a remote end of each cable from each winching station to a submersible assembly that comprises a cutter, a submersible pump, and a global positioning system having an antenna that projects above water in the pond; connecting to the submersible assembly a power cord to provide power to operate the cutter and submersible pump and a conduit through which the submersible pump can pump cuttings from the cutter; suspending the submersible assembly from the cables below a surface of the pond and activating the cutter and submersible pump; and controlling in a coordinated manner the operation of the winches from each winching station through a controller, the controller receiving signals from the global positioning system as to the position of the submersible assembly in the pond and moving the submersible assembly in a dredging pattern through the coordinated operation of the winches.
