A sediment removal system includes a vessel adapted to float on the surface of a body of water, and a crawler adapted to be submerged in the body of water, wherein the crawler includes a drive system for moving the crawler across a bottom of the body of water, and wherein the crawler includes a suctioning device that supplies a suctioning force that is utilized to remove sediments resting on the bottom of the body of water. The sediment removal system also includes a sediment removal line in communication with the suctioning device and adapted to carry the sediment from the suctioning device away from the crawler. The sediment removal system further includes at least one supporting line extending downwardly from the barge to the submerged apparatus thereby tethering the submerged apparatus to the barge, and at least one tensioning device in mechanical communication with the support line, wherein the tensioning device maintains a tensioning force in the support line at all times, thereby removing any slack within the support line between the vessel and the crawler and requiring the vessel to track substantially close on the surface of the water with the crawler as the crawler tracks along the bottom of the body of water.
