Zebra mussels have been confirmed in Jewett Lake in Otter Tail County and Floyd Lake in adjacent Becker County, according to the Minnesota Department of Natural Resources.
Watershed district staff alerted the DNR to the discovery of an adult zebra mussel attached to a native clam in Floyd Lake. DNR invasive species specialists found several adult zebra mussels in three areas of the lake.
Swimmers reported finding two adult zebra mussels on Jewett Lake. DNR invasive species specialists found several adult zebra mussels in three areas of the lake.
“It’s helpful when people recreating or working on a lake contact the DNR when they find a suspected invasive species,” DNR assistant invasive species specialist Mark Ranweiler said.
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.
Some invasive species are small and difficult to see at the access. To remove or kill them, take one or more of the following precautions before moving to another waterbody:
- Spray with high-pressure water.
- Rinse with very hot water (120 degrees Fahrenheit for at least two minutes or 140 degrees for at least 10 seconds).
- Dry for at least five days.
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.
People should contact an area DNR aquatic invasive species specialist if they think they have found zebra mussels or any other invasive species.
