The DNR reminds boaters of the state’s invasive species laws: Clean watercraft 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.

The Minnesota Department of Natural Resources has confirmed a report of zebra mussels in Rush Lake in Otter Tail County, near several other lakes where zebra mussels were previously confirmed.

Rush is located south of Perham, and northeast of Otter Tail Lake in East Otter Tail County.

DNR invasive species specialists confirmed two adult zebra mussels in separate locations about 75 feet from the public access. Signs at lake accesses have been updated to alert boaters to the presence of zebra mussels.

The spread of invasive species is not inevitable, even when lakes are near others where zebra mussels and other invasive species have been confirmed. Zebra mussels are an invasive (non-native) species that 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. Less than two percent of Minnesota’s 11,842 lakes are listed as infested with zebra mussels.
