The Sudbury Reservoir is a significant artificial lake located in eastern Massachusetts, primarily within the towns of Southborough and Marlborough, about 25 miles west of Boston. Despite its name, no part of this expansive body of water lies within the town of Sudbury. Situated at an elevation of 75 meters, this reservoir was created by impounding the Stony Brook branch of the Sudbury River with the construction of the Sudbury Dam, serving as a crucial emergency backup water supply for the greater Boston metropolitan area. The surrounding nearly 5,000 acres are managed by the Massachusetts Department of Conservation and Recreation (DCR), offering a blend of natural beauty and historical significance.
Visitors consistently praise the Sudbury Reservoir for its serene and scenic environment, making it a popular destination for those seeking tranquil outdoor experiences. The views out over the waters, especially from various viewpoints along its irregular shoreline, are particularly stunning.

The area's forested landscape, numerous inlets, and small islands contribute to its charm, providing a peaceful escape from urban life.
Before visiting, it's important to note that access to the Sudbury Reservoir is regulated to protect its role as a drinking water source.
