Zebra Mussels

Attention boaters, lake shore residents, and outdoor enthusiasts:


As you remove your boats, lifts, and other water craft this fall, please make sure to check them for invasive species.  Two lakes in Scott County currently have zebra mussels: Upper and Lower Prior Lakes.  We need everyone’s help to keep them from spreading.  

This short video summarizes what to look for and what to do to prevent the spread of zebra mussels and other aquatic invasive species.


How do I know it is a Zebra Mussel?


Learn more about what Zebra Mussels look like in this DNR fact sheet.  

If you find zebra mussels or anything else that looks suspicious attached to your equipment, please contact the Department of Natural Resources at 1-651-259-5100.  Please ask to speak to an Aquatic Invasive Species (AIS) Specialist.

Zebra Mussels stick to everything from other mussels to shopping carts.  They're sharp and can cut the feet of dogs and swimmers.
