Water lovers of all ages are invited to join the statewide search for aquatic invasive species (AIS) on August 8, 2026. This fun, hands-on effort, known as Aquatic Invasive Species Snapshot Day, relies on participants to monitor streams, lakes, and wetlands at designated sites for signs of non-native plants and animals that pose risks to Wisconsin waterways and wildlife.

Locally, Walworth County’s Land Use & Resource Management Department will host a Snapshot Day event from 8:30 a.m. to 12:30 p.m. Participants will meet at Walworth County Government Center, 100 W. Walworth St., Elkhorn, for a brief training before heading out to a handful of locations throughout the County on the hunt for AIS.

“AIS Snapshot Day is a great opportunity for residents to get involved in protecting their local waterways,” says Walworth County Land Use & Resource Management Deputy Director Mandy Bonneville. “The success of this event truly depends on volunteers; we hope Walworth County residents will join us on August 8!”

Snapshot Day is coordinated in partnership with UW-Madison Division of Extension, the Wisconsin Department of Natural Resources, and more than 20 other partners. Information collected during the event will be provided to the Wisconsin Department of Natural Resources to inform and guide monitoring and response efforts.

This is a free event. Recommended for ages 8 and up; minors must be accompanied by an adult.
