DCR Watershed Public Access Rules and Maps

Find rules and maps that describe public access activities in DCR's drinking water supply watersheds.

DCR Division of Water Supply Protection (DWSP) manages over 100,000 acres of land and 30,000 acres of water across the watershed system that provides the source waters to the Massachusetts Water Resources Authority (MWRA) for treatment and distribution to more than three million people.  

Public access and recreational uses of water supply property are complex issues.  Any human activity on or near water supply source waters can introduce disease-causing agents or pollutants to the drinking water supply.  Water supply managers must exercise caution when considering policies for public access and recreation on water supply lands. 

DWSP and MWRA must meet strict state and federal laws as one of the few unfiltered drinking water supplies in the nation.  At the same time these reservoirs and lands are valuable natural resources that attract the public to explore and recreate.  DWSP's public access management plans determine the levels of access that may be reasonably allowed without risking water supply safety, security, or quality.

The following sections provide links to many maps created during the Public Access Management Plan process, and are accurate at the time of publication.  Please refer to the on-line, interactive public access map app for up-to-date information regarding roads, trails, and other recreation related activities.

Rules and Regulations

All of DWSP's Public Access Policies are based on 313 CMR 11.09, the General Rules and Regulations for the Protection of Watersheds and Watershed System.

Watershed Protection General Rules and Regulations 313 CMR 11.09

Each of the four watersheds have policies developed through a Public Access Management Plan.  The maps below reflect these policies.

Quabbin Reservoir Watershed

The Gate 30 parking area off Route 122 in New Salem, and all access to the Quabbin Reservation from this location, is closed as of July 10, 2021.  The road just inside Gate 30 crosses the Swift River over a keystone bridge; DCR engineers have determined that damage to both the bridge and road make them no longer safe for public use until repairs can be completed.  DCR recommends using Gate 29 on Route 202 to access this section of the Quabbin Reservation.

Interactive Public Access Map

The Division of Water Supply Protection has developed an interactive map with detailed information about public access roads and trails, fishing, and hunting in the Quabbin Reservoir, Ware River, Wachusett Reservoir, and Sudbury Reservoir watersheds.  There are two ways to access this map: one is an online program that is accessible from your desktop computer or mobile device’s web browser; the other is through an App you can download directly to your mobile device and use in the field.  The mobile device App is recommended for use in the field.
