Abstract

A novel method of removing material from the bed of a pond, lake or like body of water utilizing a floating hull having a bow and stern by drawing water from the body of water at a point closely adjacent the hull, forming the drawn water into a plurality of generally parallel pressurized streams inclined to the horizontal directed rearwardly from the stern, releasing the pressurized streams in the body of water at points substantially removed and generally equidistant from the hull and adjacent the material thereby creating a material-water admixture and simultaneously propelling the hull in a forward bow leading direction, withdrawing the material-water admixture from the body of water, and additionally forming the drawn water into two additional pressurized streams which are selectively released in the body of water at points sidewise removed from the hull adjacent the bow and below the water surface for steering the hull during its forward stern-leading motion.
