Diver Assisted Suction Harvesting
Diver Assisted Suction Harvesting (DASH) is the extraction of plants using a Hookah system, suction tube, and a unique set of pumps. These components are mounted on a boat with a bagging or filtration system. Suction harvesting is a viable means of plant suppression because the entire plant is removed from its connective root.
Aquatic Herbicides are products used to kill aquatic weeds or severely stunt their growth. We apply the herbicide directly to the plants from a boat through weighted hoses connected to a pump and tank. There are many different kinds that target specific plants leaving others unaffected. The two main types are contact and systemic. Systemic herbicides are absorbed into the plant and moved to other tissue affecting the entire plant. Contact herbicides are lethal to all plant cells that they encounter. We consider many different factors such as the type, growth, and density of targeted plants when choosing the proper product and use the minimum amount to most effectively and safely control selected weeds.
These barriers are specially made sheets of materials such as fiberglass, polypropylene, or polyvinyl chloride (PVC). They are anchored to the lake bottom which prevents plant growth by blocking sunlight. Bottom barriers are most appropriate in localized areas such as swim areas, around docks or to create boat lanes out to deeper water.
