2026 Fall Gallatin Watershed Cleanup
Saturday, September 19, 2:00-6:30 p.m.
Help us clean up our watershed after the end of a busy recreation season!
We have all been enjoying Southwestern Montana’s outdoor spaces this summer. Now, let’s give back! Help us clean up our watershed after the busy recreation season. The Gallatin Watershed Council (GWC) and the Gallatin River Task Force (GRTF) are hosting the eighth annual collaborative Gallatin Watershed Cleanup. Join us in removing trash from the entire Gallatin Watershed, from Yellowstone National Park to the Missouri Headwaters, to keep the water clean for our community and downstream neighbors.

Team Leader
Team leaders are responsible for attending a team leader happy hour the week of the event to collect supplies, then distributing supplies and relaying safety information and protocol to their team members. Detailed responsibilities are linked below.
You will also receive additional information via email closer to the event date.
Volunteer
Volunteers choose a site that they want to clean up, sign a waiver and show up! We recommend wearing gloves and clothes that you feel comfortable picking up trash in. Otherwise, we provide the bags, rubber gloves, and hand sanitizer. The volunteer who finds the strangest thing will win a raffle prize at our Post Cleanup Celebration.
