ABSTRACT:
An apparatus and method for removing sediment which has settled on the bottom of a pond comprising a frame and a hydrostatic chamber. The hydrostatic chamber includes an aperture to receive the sediment and water proximate the bottom of the pond. A gate controls the size of the opening of the aperture formed in the hydrostatic chamber thereby regulating the ratio of sediment to water entering the hydrostatic chamber. An underwater motive means moves the apparatus along the bottom of the pond causing a wiper to extend into the sediment for scraping, loosening, wiping and plowing the sediment from the bottom of the pond and for directing the bottom sediment toward the aperture upon movement of the frame by the motive means. A vent is used to vent the hydrostatic chamber while a pump is in fluid communication with the hydrostatic chamber to create a pressure differential thereby forcing into the hydrostatic chamber the sediment and fluid proximate the aperture. This sediment and fluid is pumped out for disposal away from the pond.
