Zebra mussels found along shoreline of the Clay County lake

The Minnesota Department of Natural Resources has confirmed the presence of zebra mussels in Lee Lake, near the city of Hawley in Clay County. 

A lake property owner contacted the DNR after noticing zebra mussels along the shoreline and attached to a rock. A DNR invasive species specialist found adult zebra mussels on a dock at the Lee Lake public water access and at a second location about three-quarters of a mile from the public water access.  

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 webpage of the DNR website.

• Spray watercraft and equipment 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 webpage of the DNR website.
