Dane County Water Resource Engineering Division, Administration Division and the Office of Lakes and Watersheds work closely with the Wisconsin Department of Natural Resources to develop main goals for water plant harvesting. These goals are used to help keep waterways open for recreational use and to also protect and nurture native plant growth. Harvesting goals are based on need and not all areas listed are harvested in a given season. Harvesting follows permit requirements from the Wisconsin Department of Natural Resources and approved Aquatic Plant Management Plans for each waterbody. Harvesting machines are cleaned to remove any invasive plants and animals before being moved from one body of water to another.
