Zebra Mussels Confirmed in Pine Mountain Lake in Cass County
The Minnesota Department of Natural Resources has confirmed a report of zebra mussels in Pine Mountain Lake, adjacent to Backus in Cass County.
According to the release, a swimmer contacted the DNR after finding a zebra mussel attached to a native mussel on a sandbar along the southern shoreline of the lake. A DNR invasive species specialists found three more zebra mussels during a snorkel search in the same area.
“It’s helpful when lake users contact us if they find what might be an invasive species that’s new to a lake,” said Heidi Wolf, DNR invasive species unit supervisor. “Early detection is important, because it can help prevent spread to other lakes.”
Whether or not a lake is listed as infested, Minnesota law requires boaters and anglers to:
- Clean watercraft and trailers of aquatic plants and prohibited invasive species,
- Drain all water by removing drain plugs and keeping them out during transport, and
- Dispose of unwanted bait in the trash.
People should contact a Minnesota DNR aquatic invasive species specialist if they think they have found zebra mussels or any other invasive species.
