The Saw Mill River Coalition

About the Saw Mill River Coalition

The Saw Mill River Coalition is a dynamic partnership of nonprofit groups, government agencies, municipalities and businesses dedicated to revitalizing and protecting the Saw Mill River, a tributary of the Hudson River.

The Annual Great Saw Mill River Cleanup

The annual event hosted by Groundwork Hudson Valley and the Saw Mill River Coalition is held across Yonkers and Westchester County drawing hundreds of enthusiastic volunteers for a day full of unity and environmental restoration.

The Saw Mill River is a key natural resource for the County and this event is an incredible effort to clean and restore the river and improve the environmental health of the communities around it.

The Great Saw Mill River Cleanup returns on Saturday, April 26, 2025!
