2026 Fall Gallatin Watershed Cleanup

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.
