Abstract: An apparatus and method for cutting plant growth from waterways to promote fluid passage through such waterway. Water under high pressure is forced through a nozzle orifice to cut, chop and/or pulverize the aquatic plant matter. The nozzle is on a spray-head assembly of the apparatus, which is positioned above or in the waterway by the boom of a vehicle such as, for example, a crane or backhoe. As the transport machinery and apparatus are advanced in the waterway, a path is cut through aquatic plant matter by the high pressure water from the nozzle, and, as a result, the waterway may be effectively cleared. In the preferred apparatus and method, wherein the nozzle directs the water vertically into the waterway, a steel plate may be submerged beneath the level of the nozzle and above the soil surface to protect the soil from disruption and erosion.
