The Minnesota Department of Natural Resources has confirmed a zebra mussel in East Battle Lake in Otter Tail County.

A lake property owner removing equipment from the lake for the season contacted the DNR after finding an adult zebra mussel attached to a dock post, according to a news release. DNR divers did not find any additional zebra mussels after searching 20 other pieces of equipment that had been removed from the lake and 350 objects in four areas of the lake.

As with any such confirmation of a specimen, East Battle Lake is listed for zebra mussels, and invasive species signage has been posted at accesses, according to the release. The DNR will continue to monitor East Battle Lake for zebra mussels and other aquatic invasive species.

The DNR recommends these steps for lake property owners:

  • Look on the posts, wheels and underwater support bars of docks and lifts, as well as any parts of boats, pontoons and rafts that may have been submerged in water for an extended period.
  • Hire DNR-permitted lake service provider businesses to install or remove boats, docks, lifts and other water-related equipment. These businesses have attended training on Minnesota’s aquatic invasive species laws and many have experience identifying and removing invasive species.
