The DNR will add a lake, river, pond or wetland to the infested waters list if it contains an aquatic invasive species that could spread to other waters. The DNR may also list a lake, river, pond or wetland as infested if it is connected to a body of water where an aquatic invasive species is present.
To reduce the risk of spreading aquatic invasive species, activities like bait harvest and water use are managed differently in infested waters.
You can download the infested waters list as an Excel spreadsheet . Last updated November 20, 2017. This Excel spreadsheet is the most complete version of the infested waters list and should be used for regulatory or permitting purposes.
You can view an interactive map of most infested waters on the EDDMapS Midwest website.
About 5% of Minnesota's more than 11,000 lakes are on the infested waters list. Less than 2% of Minnesota lakes are listed as infested with zebra mussels. As of August 2016, we have confirmed zebra mussels in 121 lakes, rivers and wetlands. We have listed 130 bodies of water as infested with zebra mussels because they are closely connected to a waterway where zebra mussels have been found.
You can help stop the spread of aquatic invasive species. Take three steps every time you leave a lake or river - whether or not it's infested:
