State wildlife officials first discovered New Zealand mudsnails in South Boulder Creek in 2004 and are taking action to prevent them from spreading. The New Zealand mudsnail competes with native invertebrate species and can destroy forage important to trout and other native fishes. Learn more how to identify the New Zealand Mudsnails, how to stop the spread and how to report sightings.
