Zebra Mussels Confirmed in Itasca County Waters
DULUTH, Minn. – The Minnesota Department of Natural Resources has confirmed zebra mussels in Dora Lake and connected waters in Itasca County, as well as in Serpent Lake in Crow Wing County.
Itasca County aquatic invasive species staff found zebra mussels downstream of Sand Lake, where zebra mussels had been confirmed in 2013. DNR officials have now confirmed zebra mussels at the Shogren Dam; Dora Lake, a small, shallow lake down stream of Sand Lake; and in the Big Fork River, seven miles down stream from Dora Lake near Wirt.
The DNR is urging Minnesota residents to check for zebra mussels when docks and boat lifts are being removed from waters at the end of the season. It is important to check posts, wheels, and underwater support bars of docks and lifts, as well as any parts of watercraft that have been submerged for an extended period of time.
Minnesota law requires docks and lifts be allowed to dry for at least 21 days before being placed into another body of water – no matter the status of invasive species.
Law also requires boaters and anglers to:
- 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.
