Zebra mussels confirmed in two Ramsey County lakes

The Minnesota Department of Natural Resources (DNR) has confirmed reports of zebra mussels in Bald Eagle Lake and Lake Johanna in Ramsey County.

The DNR is conducting follow-up surveys of the lakes to determine whether zebra mussels are distributed more broadly and assess whether there are treatment options. Early detection increased the potential for treatment and will help prevent the spread to other lakes.

Ramsey County has an active Aquatic Invasive Species (AIS) Prevention Program and coordinates inspections at the Ramsey County public boat launch sites. Efforts will be made to increase the inspection hours at Lake Johanna and Bald Eagle Lake for the remainder of the summer.

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.
  • Dispose of unwanted bait in the trash.

Zebra mussels can compete with native species for food and habitat, cut the feet of swimmers, reduce the performance of boat motors, and cause expensive damage to water intake pipes.

More information is available on the DNR’s website.
