DCR-DWSP Watershed Boundaries

This feature layer depicts the four watersheds that make up Massachusetts public water drinking supply. The three primary watersheds are the Quabbin Reservoir, Ware River and Wachusett Reservoir, while the Sudbury watershed represents an emergency drinking water supply. This layer was developed by the Department of Conservation and Recreation (DCR), Division of Water Supply Protection (DWSP).本要素图层（Feature Layer）涵盖构成马萨诸塞州公共饮用水供水系统的四大流域。其中三大核心流域分别为夸宾水库（Quabbin Reservoir）、威尔河（Ware River）与沃楚西特水库（Wachusett Reservoir），萨德伯里流域（Sudbury Watershed）则作为应急饮用水供水保障流域。本图层由马萨诸塞州保护与娱乐部（Department of Conservation and Recreation, DCR）下属的供水保护处（Division of Water Supply Protection, DWSP）开发完成。
