Infested Waters List
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.
Which lakes and rivers are listed as infested?
You can find out if a body of water is infested by:
- Searching for a lake on LakeFinder, or
- Downloading the infested waters list as an Excel spreadsheet or PDF file.

How many lakes and rivers are listed as infested?
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 July 2015, we have confirmed zebra mussels in 98 lakes, rivers and wetlands. We have listed 131 bodies of water as infested with zebra mussels because they are closely connected to a waterway where zebra mussels have been found.
What can I do?
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:
- Clean all aquatic plants, zebra mussels, and other invasive species from boats, trailers, and water-related equipment.
- Drain water from your boat, ballast tanks, motor, live well and bait container. Remove drain plugs and keep drain plugs out while transporting equipment.
- Dispose of unwanted bait in the trash. To keep live bait, drain the water and refill the bait container with bottled or tap water.
