Join us for a statewide, one-day event to connect volunteers, water lovers, and local groups in a search for aquatic invasive species (AIS).

Learn about aquatic invasive species with a short training, then get outside to monitor a site and collect samples.
Return to your Training Site to confirm your finds and celebrate.

This is a free, family-friendly event. Recommended for ages 8 and up, minors must be accompanied by an adult.
Hosted by River Alliance of Wisconsin, in partnership with St. Croix River Association, Polk County and many more!
