The Charles River Conservancy is a non-profit citizens advocacy group dedicated to the renewal and stewardship of the 400 acres of Charles River parklands from the Boston Harbor to the Watertown Dam. More than 2,500 Conservancy Volunteers help each year to revive and maintain the Charles River Parklands. Volunteers plant daffodils, paint park benches and railings, remove invasive plans, trim brush and reclaim parkland. There are volunteer projects for individuals, families and small and large groups. In the spring, summer and fall there are many open one-time volunteer projects.
