Aquatic Plant Management (APM)

How we manage weeds throughout the year

April - May 2021

Initial Weed Treatments

Working with Wisconsin Lakes and Ponds we use targeted chemical treatments while weeds are in their initial growing state. This yields the best results. 

June 2021

Weed Cutting Begins

This process begins once plants reach a minimum growing height and can be harvested successfully. 

July 2021

Weed Harvesting Begins

Weed Harvester will hopefully begin harvesting weeds within navigable channels. With the implementation of a new harvester, we hope to remove weeds in areas previously inaccessible to traditional weed cutters. 

July-September 2021

Weed Harvesting Continues

Harvester will work throughout the summer months to manage areas that need attention. Riparian owner feedback and input will be vital as we operate and evaluate the harvester's effectiveness throughout the intial year of usage.

Managing weeds

One of the most important projects the WWMD heads up each year is the control, treatment, and removal of aquatic weeds with a special emphasis on invasive species such as Eurasian Water Milfoil in the lake. It is important to remember that the measures employed by the WWMD are designed to ensure that the lake remains navigable for all of the users of the lake, not to remove all of the weeds (which play an important role in the ecosystem) or to remove all of the weeds from sight. Further, based on limited resources and DNR regulations, the WWMD prioritizes weed control activities that will allow continuing navigation for use of the waterway. Weed control and removal is not oriented toward enhancing scenic beauty but rather to make sure the lake is not overrun by weeds thereby limiting access to the lake’s users. We are currently doing EVERYTHING the DNR will allow us to legally do to control the weeds. We are strictly limited to those areas and activities authorized by the DNR.
