A North Shore lake has been designated as infested with an invasive species.

According to the Minnesota DNR, an aluminum can encrusted with zebra mussels was found at Crooked Lake in Lake County. The body of water is located about 20 miles northeast of Finland.

The initial discovery was reported by Fond du Lac Band of Chippewa biologists, who found the can while doing fisheries assessments. The DNR then searched the lake but failed to find any additional invasive species.

"Although we weren't able to locate additional adult zebra mussels on the first survey, designating the lake now as an infested water body is the right thing to do," said Rich Rezanka, DNR invasive species specialist. "Lake users should follow the AIS protocols every time, at every lake, as if it were infested - whether signs are posted, or not."

Additional searches of Crooked Lake and connected waters will be performed to determine the scope of the infestation, according to the DNR. Those connected bodies of water are:

  • Artlip Lake
  • Houghtailing Creek
  • Wanless Creek
  • Cross River

The DNR says bait harvest and transport of water for any purpose is prohibited in infested waters. Before leaving any water access or shoreland, anglers, boaters are reminded to remove all aquatic vegetation, drain all water by removing drain plugs, and keep drain plugs out while transporting watercraft.
