Aquatic Weed Harvester Effective in Maintaining New Zealand Waterways
Introduced aquatic weed clogs 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 and because it works over water stringent safety, health and environmental protocols are followed. Lakeweed Harvesters do not use chemicals and where necessary use biodegradable products.

Lakeweed Harvesters and Contractors have removed between 3.2 to 4.3 tonne of weed annually from Lake Rotoehu since 2008 resulting in a dramatic improvement in water quality.

Chemical Promotes Dangerous Algae Blooms - Wisconsin is not fully enforcing strict phosphorus limits adopted two years ago to reduce lake-algae blooms that make people sick. The state Legislature in 2010 approved DNR regulations intended to cut down on the amount of phosphorus running into waterways, where it causes algae to grow so thick that the water turns to green soup. The regulations are aimed at wastewater treatment plants, paper mills and factories – which are required to reapply for permits at five-year intervals.
