The Minnesota Department of Natural Resources is confirming a report of zebra mussels Blandin Reservoir on the Mississippi River, abutting the city of Grand Rapids. 

Because several lakes are connected to the reservoir by a Mississippi River tributary, they are also being added to the infested waters list.

According to the DNR, invasive species staff confirmed zebra mussels on old saw logs and other logging relics throughout the reservoir. The Mississippi River splits near the reservoir, and a tributary connects several nearby lakes. Because of the connection, Lake Pokegama, Jay Gould Lake, Little Jay Gould Lake, and the Mississippi River from Lake Winnibigoshish to Mississippi Lake will also be added to the infested waters list.

No zebra mussels were found in recent surveys of Lake Pokegama and Jay Gould Lake, but they will be added because they are closely connected to waters with confirmed zebra mussel populations.

Remember, in order to prevent the spread of zebra mussels, 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.

Also, one or more of the following precautions should be done before moving to another waterbody:

  • Spray with high-pressure water.
  • Rinse with very hot water (120 degrees for at least two minutes or 140 degrees for at least 10 seconds).
  • Dry for at least five days.
