DCR Office of Watershed Management

The Office of Watershed Management within DCR's Division of Water Supply Protection manages and protects the drinking water supply watersheds for approximately 3 million residents of Massachusetts, primarily in Greater Boston.

The Quabbin Reservoir, Ware River, and Wachusett Reservoir watersheds are the sources of drinking water for treatment and distribution by the Massachusetts Water Resources Authority (MWRA).
