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 City of Keene, The Ashuelot River Local Advisory Council, The Cheshire County Conservation District, Keene State College, Moosewood Ecological, The Keene Young Professionals, and Keene State College, NH Water Works Association Young Professionals, and The Harris Center for Conservation Education.

Join us September 29-30th for the 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 29-30th, 2023, 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!
