The Minnesota Department of Natural Resources has confirmed the presence of zebra mussels in Lake Bronson, near the city of Lake Bronson in Kittson County.
Lake Bronson is located in Lake Bronson State Park. Park staff reported a zebra mussel attached to a rock near a public access. A DNR invasive species specialist found more adult zebra mussels in the same area.
Whether or not a lake has any invasive species, Minnesota law requires people to:
- Clean watercraft, trailers and equipment to remove aquatic plants and prohibited invasive species.
- Drain all water and leave drain plugs out during transport.
- Dispose of unwanted bait in the trash.
- Never release bait, plants or aquarium pets into Minnesota waters.
- Dry docks, lifts and rafts for 21 days before moving them from one water body to another.
These additional steps reduce the risk of spreading aquatic invasive species:
- Decontaminate watercraft and equipment – find free stations on the courtesy decontamination page of the DNR website.
- Spray watercraft and equipment with high-pressure water or rinse with water if high-pressure water is not available.
- Dry watercraft and equipment for at least five days before using in another water body.
People should contact a Minnesota DNR aquatic invasive species specialist if they think they have found zebra mussels or any other invasive species that was not already known to be in the water body.
Lake Bronson has been drawn down as part of a DNR project to replace the aging Lake Bronson Dam. While the park remains open, access to the lake is prohibited and no fishing is allowed during the project to ensure public safety and protect sensitive resources in the project area. Project completion is anticipated by July 2027. More information is available on the park webpage.
