Middlesex Fells Reservation, often referred to simply as the Fells, is a public recreation area covering more than 2200acre in Malden, Medford, Melrose, Stoneham, and Winchester, Massachusetts. The state park surrounds two inactive reservoirs, Spot Pond and the Fells Reservoir, and the three active reservoirs (North, Middle, and South) supplying the town of Winchester. Spot Pond and the Fells Reservoir are part of the Wachusett water system, one of six primary water systems that feed metropolitan Boston's waterworks. The park is managed by the Massachusetts Department of Conservation and Recreation and is part of the Metropolitan Park System of Greater Boston.
