 New cases of zebra mussels have been confirmed in lakes in Crow Wing and Itasca counties. The Minnesota DNR has confirmed zebra mussels in Serpent Lake in Crow Wing County and in Dora Lake and Connected Waters in Itasca County. A lake service provider business removing a dock from Serpent Lake in Crow Wing County contacted the DNR after finding suspected zebra mussels. A DNR invasive species specialist confirmed zebra mussels attached to vegetation hanging from a removed dock at a second location at the Highway 6-210 public access point about 1.3 miles away from the originally reported location. In Itasca County, aquatic invasive species staff found zebra mussels downstream of Sand Lake where zebra mussels were confirmed in 2013. The DNR confirmed zebra mussels at the Shogren Dam, Dora Lake, a small shallow lake downstream of Sand Lake and in the Big Fork River, 7 miles downstream from Dora Lake at the Itasca County Road 31 crossing near Wirt.
