Source to Sea River Clean Up
Each Fall a large group of enthusiastic volunteers pitch in to help clean up the Ashuelot River and its tributaries in Keene, Swanzey and Winchester as part of the Connecticut River Conservancy’s “Source to Sea Cleanup”.
This event is made possible with the partnership of the Keene Conservation Commission, Keene High School, KUUC Outdoors (Keene Unitarian Universalist Church), the Ashuelot River Local Advisory Committee, the City of Keene, Savings Bank of Walpole, Keene State College, and the Keene Lions Club.
Join us September 19th for the 30th Annual Source to Sea River Clean Up!
Join thousands of volunteers across New England to clean up the Connecticut River and its tributaries on September 19th, 2026, as part of the annual Connecticut River Conservancy’s Source to Sea Cleanup! This coordinated effort is a chance to spend a fun day on the river and give back to our shared waters!
Sites include both on-foot and boating locations. Volunteers should only be using small boats such as kayaks, canoes, and paddle boats, due to limited space on the river.
