The Minnesota Department of Natural Resources has confirmed the presence of zebra mussels in Pine Lake, near Saint Anna in Stearns County.
A lakeshore resident contacted the DNR after finding a zebra mussel on a rock in front of their property. In follow-up searches, a DNR invasive species specialist found another adult zebra mussel attached to a log on the south end of the lake.
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 with high-pressure water or rinse with very hot water (120 degrees for at least two minutes or 140 degrees for at least 10 seconds).
- 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.
More information is available on the aquatic invasive species page of the DNR website.
