BLACK EARTH, WI (WTAQ) - The invasive New Zealand mud-snail has been spotted in Dane County.
The state DNR says it's the first time the snail has been found in an inland stream in the Midwest.
Scientists from UW La Crosse recently confirmed that the New Zealand mud snail was found in a water sample taken from Black Earth Creek last year.
The sample was part of a routine monitoring for invasive species.
The same type of snail was spotted earlier in the Great Lakes, and waters in the western United States.
