Introduced aquatic weeds clog many of New Zealand’s waterways. It affects aquatic life and prohibits access and use for recreational users. Lakeweed Harvesters remove the aquatic plants mechanically, using a harvester mounted on a three metre by seven metre pontoon vessel. The operation works under strict standard operating procedures to ensure maximum weed is harvested
Floating weed harvesters have opened passages through Dane County Wisconsin’s dense tangles of underwater plants for about 50 years. The barges wield rotating cutting bars like those on farm combines to cut a submerged crop that is fertilized too well by runoff of nutrients like dairy manure. Each spring, the county launches a flotilla of
Pewaukee Lake is the largest of the ninety-one lakes located in Waukesha County, Wisconsin. It is a premier lake for Musky, Walleye, Northern Pike, and Largemouth bass.

Efforts to restore Georgica Pond are proving to be successful thanks in part to the help of an aquatic weed harvester.

However, invasive plants such as Eurasian watermilfoil, hydrilla and water hyacinth quickly take over a lake covering 60% and sometimes 100% of the
It is exhausting reading about lake after lake after lake becoming infested with an over abundance of aquatic vegetation. This plant material not only negatively affects water quality, the health of the fishery, recreation, aesthetics, but it is financially devastating as well. It affects tourism; bait shops, marinas, hotels, restaurants. It affects lake property owners;
Unlike using chemicals, or doing nothing at all, the advantages of harvesting include: – Immediate relief from nuisance plants that interfere with navigation and recreation – Immediate use of the water for swimming or irrigation – There is nothing foreign introduced to the environment when using mechanical control – Biomass is removed from the water
