The Benefits of Fall Aquatic Weed Harvesting
As temperatures cool, fall offers the perfect opportunity to harvest aquatic weeds and prepare lakes and ponds for the next growing season. Removing excess plant material before winter helps manage nutrients, prevent algae blooms, and improve water clarity.
Fall harvesting also helps control invasive species, allows easier access with lower water levels, and sets the stage for a healthier ecosystem come spring.

Strategic Aquatic Plant Harvesting as a Multi-faceted In-Lake Management Tool
Research on Kohlman Lake in Minnesota shows how mechanical aquatic plant harvesting can play a vital role in improving water quality and supporting balanced lake management.
By selectively removing about 14% of peak plant mass, researchers found that harvesting eliminated 24% of the phosphorus captured by plants—making it a cost-effective method compared to traditional watershed management practices. Beyond improving navigation and recreation, strategic harvesting contributes to healthier, clearer lakes.

Protecting the Lake
Pewaukee Lake was created in 1838 and has faced decades of aquatic plant management challenges. For years, herbicides were used to control invasive weeds—but in 1985, the Lake Pewaukee Sanitary District discontinued chemicals and expanded its mechanical harvesting program instead.
By removing plants rather than killing them with herbicides, the district has reduced nutrients that fuel regrowth, encouraged native plant diversity, and supported a healthier ecosystem—all while balancing recreation and environmental protection.
