Diver Assisted Suction Harvesting (D.A.S.H.) Lake Weed Removal Services
Diver-Assisted Suction Harvesting (D.A.S.H.) is one of the most precise and environmentally responsible methods available for managing invasive aquatic plants. The process combines the expertise of trained divers with a specialized suction system, allowing invasive vegetation to be selectively removed while minimizing disturbance to desirable native plants and sensitive aquatic habitats.
Working underwater, our divers carefully identify and hand-harvest target species, extracting the entire plant, including the root system, whenever possible. Removing the root provides a more effective solution than simply cutting the vegetation, reducing regrowth and helping to combat the plant infestation. This selective approach also encourages native plant communities to naturally recolonize areas previously dominated by invasive species.
Our custom-designed D.A.S.H. boats maximize both efficiency and environmental protection. Harvested vegetation is conveyed through suction hoses directly onto the deck of the vessel, where it is discharged into mesh collection bags. The bags retain the plant material while allowing water to drain through a grated deck and return directly to the lake, minimizing turbidity and preventing loose plant fragments from escaping into the waterbody. Once filled, the bags are transported to shore for proper disposal.
