In 2021 – 2022, invasive New Zealand mudsnails were found for the first time on several Dane County streams: Token Creek, Elvers Creek, and Fryes Feeder. In response, Rock River Coalition, in partnership with Upper Sugar River Watershed Association, River Alliance of Wisconsin, and WDNR, is recruiting volunteers to search for the snails at nearby stream and river access points to determine how far the snails have spread. Collecting data about the snails’ population will help focus efforts aimed at preventing them from spreading further.
