Gallatin River Cleanup

September 5, 2025 @ 9:00 am - September 7, 2025 @ 5:00 pm
Volunteers at the gallatin river cleanup

Join us September 5-7 to clean up our community watershed! Volunteers can sign-up as a team or individually to pick up trash along the Highway 191 river corridor and along streams throughout the Big Sky community. Removing trash from rivers, streams, and the surrounding land positively impacts water quality, wildlife habitat, soil quality, as well as our downstream neighbors.

Where to meet: Team leaders, teams, and individuals will meet at the Big Sky Community Park  to check in and pick up supplies and snacks before heading out to a pre-assigned river section. If you or your team has not received a location, please meet us at the Big Sky Community Park. See this map for river section details.

Don’t have a group to tackle trash? No worries! Join a Task Force-led team and other individuals on a day that works for you. We will still plan to meet at the Big Sky Community Park before heading out to our cleanup sites at these times: 

  • Friday, September 5, 3:00 PM
  • Saturday, September 6, 10:30 AM
  • Sunday, September 7, 11:00 AM

What to bring: Wear comfortable walking shoes and bright or colorful clothing, and bring a water bottle. Gallatin River Task Force will provide trash bags, a limited number of gloves, buckets, high visibility vests, trash pickers, and snacks.

Win Prizes! The volunteer or team with the strangest item picked up will have the opportunity to win a prize! Additionally, volunteers can sign up for our raffle at Big Sky Community Park, featuring prizes from Simms, Pinky Gs, and Hungry Moose. 

Volunteer in Bozeman with Gallatin Watershed Council! 

Each year we partner with the Gallatin Watershed Council to host a watershed wide cleanup. If you would like to volunteer in the Lower Gallatin Watershed, please sign up at  gallatinwatershedcouncil.org.

Thanks to our partners & sponsors
