Former reservoirs in Massachusetts

The Mystic Lakes, consisting of Upper Mystic Lake and Lower Mystic Lake, are closely linked bodies of water in the northwestern suburbs of Boston, Massachusetts.

The Framingham Reservoir No. 1 Dam and Gatehouse is a historic water works facility in Framingham, Massachusetts. This complex is located at the end of Framingham Reservoir No. 1, which is also known as the Stearns Reservoir, off Winter Street and north of Long Avenue. Constructed from 1876 to 1878 as part of an expansion of the water supply of the city of Boston, this was designed by its first city architect George A. Clough. The historical purpose of the reservoir, which was located at the confluence of two branches of the Sudbury River, was primarily to control the river's water level, and secondarily to provide reserve supply capacity. The reservoir's reserve capacity was generally used only as a backup supply, as the reservoir's muddy bottom made it a less desirable source than reservoir No. 3 upstream. However the reservoir No. 1 system was nonetheless important due to its role in controlling the flow of the river downstream, and due to the gatehouse which controlled the water flows for all the Framingham reservoirs into the Sudbury Aqueduct. Reservoir No. 1 is no longer maintained as a reserve water source, although it is still owned by the Massachusetts Water Resources Authority, successor to the Boston Water Board which oversaw its construction. MWRA retains ownership as the gatehouse contains the connection between Reservoir No. 3 and the Sudbury Aqueudct which remain part of the emergency water systems.

Lake Cochituate is a body of water in Natick, Wayland, and Framingham, Massachusetts, United States. Originally a reservoir serving Boston, it no longer serves that function, and is now a local recreational resource and home to Cochituate State Park.

The Framingham Reservoir No. 2 Dam and Gatehouse is a historic water works facility in Framingham, Massachusetts. The dam and gatehouse are located west of the junction of Winter and Fountain Streets, and impound a branch of the Sudbury River. The reservoir, which is also known as the Brackett Reservoir, was built 1877-79 as part of an expansion of the water supply of the city of Boston. The dam is 1,376 feet (419 m) in length, with a centered overfall area. The core of the dam is granite rubble laid in cement, with earthen embankments. The overfall area is faced on the downstream side with cut granite, and earthen embankment on the upstream side. It is topped with granite and originally had iron mounts for flashboards. The gatehouse is a rectangular granite structure with a steep hip roof, a brick chimney and an eyebrow dormer. The door and windows are in round-arch openings. It contains gate controls for regulating water flow from the reservoir and from a 4-foot (1.2 m) pipe connected to Reservoir No. 1, and a 2-foot (0.61 m) pipe connected to the Ashland Reservoir.
