Dane County Office of Lakes & Watersheds has a history of bringing people and
organizations together to share solutions to the variety of challenges they all
face, such as monitoring, strategic partnering, capacity building, volunteer
coordination and more. Through the
Dane County Watershed Network,
organizations with a connection to lakes, rivers, streams, wetlands and more share
ideas, solve problems and learn from each other.

Our friendly and knowledgeable Clean Boats, Clean Waters aquatic invasives species inspectors are stationed at boat
landings throughout the county each weekend of the boating season to help stop the spread of aquatic invasive species.
Meet the Dane County staff and learn more about their work here.
The Clean Boats, Clean Waters program is one of the many ways we are implementing our
Aquatic Invasives Prevention and Control Plan.
The Dane County Lakes and Watershed Commission and staff at the Office of Lakes
and Watersheds are part of an exciting partnership working to protect and improve
the Yahara River chain of lakes, including Lakes Mendota, Monona, Wingra, Waubesa,
and Kegonsa. Lake users, residents, and other stakeholders are working together
to implement Yahara CLEAN Report and Yahara CLEAN Strategic Action Plan priority lake improvement recommendations, which in turn
will help make our 'practical vision' for the future of the lakes a reality. Additional
reports and background on the Yahara CLEAN report are available on the Yahara Portal.
Dane County, Wisconsin Department of Natural Resources, and the US Army Corps
of Engineers completed the Turville Bay research project in 2013 and published
the results as a fact sheet
and project report. This
project evaluated the response of selective early-season herbicide application
and cutting of aquatic plants on Turville Bay, the southwest area of Lake
Monona, on Eurasian water milfoil (EWM, an invasive aquatic exotic plant) and
on native plant communities.
Eurasian water milfoil begins growing early in the year, and creates a dense
growth canopy which shades out native plant species. Cooperating scientists and
managers wondered if controlling EWM early in the season would give an
advantage to native plants. The research project found that both herbicide and
harvested early-season treatment resulted in significant decreases in EWM.
Mechanical harvesting produced more variable results, but better protected
native coontail plants. The herbicide treatment resulted in longer control of
EWM than mechanical harvesting.
At a November 2013 meeting sponsored by the Office of Lakes and Watersheds,
the research partners engaged in a community discussion about the project's
final report. Wisconsin DNR research scientist Martha Barton's presentation
slides are available here.
