Zebra Mussels

Attention boaters, lake shore residents, and outdoor enthusiasts

As you use your boats, lifts, and other water craft this spring/summer, please make sure to check them for invasive species before moving them to/from lakes. Two lakes in Scott County currently have zebra mussels: Upper and Lower Prior Lakes. We need everyone’s help to keep them from spreading to other lakes. Once they are in a waterbody, they are both expensive and difficult to remove. Please help us keep our waters safe and clean of aquatic invasive species.
