When dredging companies take sand and gravel out of the riverbed, the river fills the resulting hole with sand and silt removed from upstream. The Kaw is vulnerable to degradation from dredging because it is a single, connected system that naturally works to maintain balance. Download Regulatory Report River Bed Degradation In recent years, however, dredging activities have been documented through careful studies to have caused significant damage to the Kaw’s riverbed, to habitat in and along the river, and to water quality, resulting in the Corps closing stretches of the river to further dredging. Kansans have benefited from good quality roads and buildings thanks to the Kaw. Sand from the Kaw is highly sought after because of its size and shape, which make it particularly valuable to the concrete industry. These pontoon dredge pumps are suited for ponds and lagoons up to 20,000 square meters surface areas, up to 3.5 meters deep.The Kansas River has been commercially mined (dredged) for sand and gravel since the early 1900’s. The dredge pump agitates sediments and can pump up to 30% solids. The DAE Pumps pontoon dredge pumps remove sediments and slurry from tailings ponds, lagoons, and holdings ponds. DAE Pumps pontoon dredge pumps are easy to set-up and start running. These small pontoon dredges can be transported by a truck or trailer and deployed without heavy equipment. However, with DAE Pumps mini dredge pumps, this process can be completed internally to meet all environmental regulations. The facilities often outsource the maintenance to dredging companies. Power plants, paper/pulp plants, mines, chemical plants, oil fields, and other industries need to keep the capacity of their tailings and cutting ponds while following the environmental impact standards. Their designs are also poly, clay, or concrete liner safe. Ideal for lagoons, small lakes, basins, ponds, and other smaller dredging projects, these unique pontoon dredges are built with powerful, non-clogging pumps designed for high solids industrial pumping applications. The mini pontoon dredge and small pontoon dredge allow for one to two operators to run a dredge at high production rates. The DAE Pumps Pontoon Dredge Pumps are portable, robust, and smaller version dredges that are capable of dredging areas that the large dredging operations cannot access.
