  • Aquatic Plant Management Project in Turville Bay

    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.
