River Alliance Snapshot Day

This is a one-day search for aquatic invasive species across Wisconsin sponsored by the River Alliance of Wisconsin that will be held on August 18th. You can help protect your local lakes and streams by showing up at a site near you. Working together we can prevent the spread of these invasive plants and animals before they choke out our waterways. To learn more about the River Alliance of Wisconsin, click on River Alliance.
