The Weeds at River Walk
At Bakersfield’s River Walk, an aquatic weed harvester works like an underwater lawn mower, cutting and collecting weeds before they reach the surface. The harvested plants are transported to shore, where they are removed and disposed of responsibly.
This mechanical approach reduces the need for chemicals, protecting groundwater and saving costs compared to traditional herbicide treatments. The harvester’s efficiency keeps the waterways safe and accessible for everyone.

A Success Story – Lake Minnewawa Weed Harvesting
In the 1970s, Lake Minnewawa was overrun with weeds, making boating and water quality a challenge. In response, local residents formed the Save Minnewawa Association and eventually purchased an Aquarius Systems weed harvester.
Operating several months each year, the harvester clears invasive vegetation, improves water clarity, and removes excess phosphorous — reducing algae growth and supporting a healthier ecosystem. The project is funded by memberships, donations, and volunteer work, not state funds, making it a true community effort.
Thanks to years of consistent harvesting, the lake has seen significant improvements in water quality and usability, proving the value of mechanical weed management over chemical alternatives.

What is an Aquatic Weed Harvester?
Aquatic Weed Harvesters provide an environmentally friendly way to manage nuisance vegetation in lakes, ponds, and waterways of all sizes. Acting like an underwater lawn mower, they cut and collect submerged, emergent, and floating plants to keep water clear and usable.
Each machine uses a forward conveyor and cutter bars to remove weeds, storing them on board before offloading at shore. Aquarius Systems offers a range of customizable models to meet specific lake and vegetation needs, helping restore balance to aquatic environments.

DNR “Mows” Dogwood Lake
At Indiana’s Glendale Fish and Wildlife Area, DNR staff used an Aquatic Weed Harvester to manage overgrown lotus pads and coontail on Dogwood Lake. This effort helps maintain healthy waterways and ensures better conditions for fishing and recreation.
Aquatic plant harvesting provides an environmentally friendly way to control vegetation growth without chemicals — improving water quality and access for boaters and anglers.
