Gallatin River Cleanup: Volunteers can register to remove debris from the Upper Gallatin Watershed between August 21 and 23. Participants can sign up solo or with steam. Help keep our rivers clean!

Volunteers can register individually or as a team to receive a specific cleanup zone, supplies, and snacks at the Big Sky Community Park check-in point. Those who participate are also eligible to enter an event raffle supported by local sponsors. A separate cleanup for the lower watershed near Bozeman is scheduled for September 19.
