The Minnesota Department of Natural Resources has confirmed a report of zebra mussels in Lake Koronis, near Paynesville in Stearns County.

On July 8, a  fishing guide snagged an adult zebra mussel on a hook and reported it to the DNR. DNR invasive species specialists searched the area and found no other zebra mussels. During a follow-up search, the DNR found one juvenile zebra mussel near the Lake Koronis Regional Park public water access.
