YOUR SOUTHERN WISCONSIN DASH SERVICE

Diver Assisted Suction Harvesting (DASH) is a new Aquatic Invasive Species Management service. DASH is an invasive plant removal technique that offers an alternative to aquatic chemical application by suction harvesting. This allows native plant species to thrive and compete against invasive species.

What is Suction Harvesting? 

Suction harvesting is a process that removes invasive aquatic weeds while keeping diversity of beneficial plants to the lake or pond's ecosystem. Divers remove the weeds by the roots and feed them into a suction tube underwater. Meanwhile above water another worker manages the suctioned weeds and water. The suction tube leads into a water permeable bag that traps the weeds and allows the water to flow through.  Check out our DASH information page for more details or see our video below! 

What is DASH service?

Diver Assisted Suction Harvesting (DASH) is a new Aquatic Invasive Species Management service. DASH is an invasive plant removal technique that offers an alternative to aquatic chemical application by suction harvesting. This allows native plant species to thrive and compete against invasive species.


DASH stands for diver assisted suction harvesting. Our service utilizes a trained diver that floats near the bottom of the waterbody and manually pulls the plants from sediment. They are then sucked up to the harvesting boat, which safely captures the invasive plants in bags. An important benefit of using a diver to remove invasives is avoiding the application of harsh aquatic chemicals in water. Aquatic herbicides (chemicals) are linked to many side effects, such as mutations in amphibians and even impaired health of fish species and water quality. Another benefit of DASH is allowing native aquatic plants to remain in the area, so that they can continue to compete against invasive aquatic plants.


To effectively remove aquatic invasive plants, a diver must have knowledge of the growth and reproduction of the invasive plants he or she is removing. As a recent Water Resources graduate of UW-Stevens Point, I can assure you that our divers and crew members will have the best knowledge of the proper techniques in handling invasive species. This job requires a large amount of physical labor, especially during our larger jobs, but our work ethic is unmatched and we will provide each of our customers with the most effective DASH service in Southern Wisconsin. Riese Aquatics truly cares about managing aquatic invasive plant species, because they are becoming a much greater problem in our state than ever before. Just like the weeds in your garden, aquatic invasive species are persistent. In order to effectively eliminate them from a body of water, yearly maintenance of the area may be required.

   DASH vs Chemical Application        DASH vs Plant Clipping 

Using chemicals to control aquatic invasive species effects more than the targeted area. The chemicals drift to other parts of the water supply producing harm to the ecosystem, native plants, fish, and human health. Chemicals are not specific to the targeted species but to all plant species resulting in loss of native plants.


The diver is able to distinguish between invasive and native plants removing only invasive species by using suction harvesting. This allows for better pond/lake diversity and improves the ecosystems health. 

Most weed harvesting machines cut the plants giving only a temporary solution leaving a large portion of the plants in the water. This allows them to survive and continue to grow. Suction harvesting removes the roots, giving them no chance for continual growth or survival.
