DCR Watershed Plans

View the plans used to protect the drinking water supply for 2.7 million people in the greater Boston area.

DCR is continuously planning to maintain the superior water quality in the Quabbin Reservoir, Ware River, and Wachusett Reservoir watersheds.  DCR is also responsible for the emergency water supply from the Sudbury and Foss Reservoirs.

There are three critical components to the planning process for each watershed in the DCR/MWRA Water Supply System:

1. Public Access Plan -  describes the management policies that allow people to recreate on DWSP lands while still protecting water quality.
2. Land Management Plan - a thorough description of the watershed’s physical features, the natural resources on DWSP property, and the variety of techniques used by the agency to enhance water quality, including land protection and forest and wildlife management.
3. Watershed Protection Plan - takes information from the Public Access Plan and Land Management Plan and integrates water monitoring findings and other studies to create an action plan that is the basis for an annual Work Plan and budget.

There are also other plans and reports that aid in developing each of these plans.
