Intensive in-lake and watershed management caused Kohlman Lake, the northernmost lake in the Phalen Chain of Lakes in Minnesota, to go from a relatively turbid to a clear water state. Aquatic plants responded to the clean waters by growing up to the surface. The change in lake state and a comprehensive water quality monitoring dataset
In the last few decades, the lake’s weedy, northern-most portion has clogged hulls and deterred boaters from entering the lake from the Oswegatchie River. Patches of weeds greet the water’s surface near every dock, and nearly invisible from a distance on a windy day, matted greenery creates a basin of weeds seven-feet-deep in some spots.
Aquatic Plant Harvesters offer an environmentally sound method of controlling excessive aquatic plant growth and nuisance vegetation in waterways of all sizes. These heavy duty work boats are highly efficient in the management of submerged, emergent and free floating aquatic vegetation. Like an underwater lawn mower, an aquatic weed harvester cuts aquatic vegetation, collecting and storing
