Quabbin Reservoir

Quabbin Reservoir is Massachusetts' largest body of water, covering 39 square miles and providing drinking water to over 2.5 million people in metropolitan Boston while supporting extensive recreation and wildlife habitat.

The vast watershed supports black bear, moose, and bald eagles. The reservoir attracts loons and various waterfowl. The protected watershed provides exceptional habitat.

Extensive forests surrounding the reservoir include northern hardwoods and mixed woodlands. The watershed lands remain largely undeveloped.

The reservoir flooded the Swift River Valley, submerging four towns. The deep, cold water provides excellent drinking water quality.

The central Massachusetts highland location produces cool summers and cold winters with substantial precipitation.

Four towns were disestablished and thousands of residents relocated to create the reservoir. The engineering achievement represented one of the largest water supply projects in American history.

The reservoir was created between 1930 and 1939 by damming the Swift River. Recreation access is carefully managed to protect water quality.

Limited fishing access is permitted. Hiking trails explore the watershed lands. Eagle watching draws visitors in winter. The scale of the reservoir is impressive.

The visitor center at Quabbin Park provides information. Fishing access points require permits. Access is via Route 9 in Belchertown.

Watershed protection ensures continued water quality for Boston's supply. The protected lands provide exceptional wildlife habitat as a side benefit.
