The Sudbury Reservoir (2.02 square miles) is a former Boston metropolitan water reservoir located in Framingham, Marlborough, Southborough, and Westborough, Massachusetts, USA. It is now a state park administered by the Massachusetts Department of Conservation and Recreation.[2]

The reservoir was first begun in 1878, as part of a system of reservoirs fed from the Sudbury River to supplement the Lake Cochituate system in Natick. Today's reservoir was created by excavation from 1894-1898, with construction undertaken in sections. It was begun by the City of Boston but completed by the newly formed Metropolitan Water Board (predecessor to the modern Massachusetts Water Resources Authority). All told, construction required moving about 4.5 million cubic yards of soil and boulders. Water began to fill the reservoir on February 8, 1897, with construction of the reservoir's new Sudbury Dam on the Stony Brook Branch of the Sudbury River completed later that year.

When completed, the reservoir's surface area was 2.02 square miles (5.2 km2), its average depth was 17 feet (5.2 m) and maximum depth was 65 feet (20 m), and its capacity was 7.253 billion US gallons (27,460,000 m3). The reservoir was fed from the Wachusett Reservoir on the west by the Wachusett Aqueduct (1898), and by local streams. To improve the water quality of the local streams, filter beds were constructed adjacent to the reservoir. The reservoir's water was delivered to the Weston Reservoir to the east by the Weston Aqueduct (1901), or via a channel to the Framingham reservoirs and the Sudbury Aqueduct to the Chestnut Hill Reservoir.

In 1947 the obsolete Whitehall, Hopkinton, Ashland and Cochituate Reservoirs became state parks, and in 1976 the entire Sudbury System was officially reclassified as an emergency water supply. Today only the Sudbury Reservoir and the Foss Reservoir (Framingham Reservoir No. 3) remain as reserve drinking water supplies.[2]

Permitted activities[edit]

The area's limited public access allows for picnicking, hiking, snowshoeing, cross-country skiing, and shoreline fishing with restrictions.[2]
