The Framingham Reservoir No. 1 Dam and Gatehouse are a historic water works facility in Framingham, Massachusetts. They are located at the end of Framingham Reservoir No. 1, off Winter Street and north of Long Avenue. They were constructed 1876-78 as part of an expansion of the water supply of the city of Boston. The historical purpose of the reservoir, which was located at the confluence of two branches of the Sudbury River, was to control the river's water level, and to provide reserve supply capacity. It is no longer in service as part of the water supply system, although it is still owned by the Massachusetts Water Resources Authority, successor to the Boston Water Board which oversaw its construction.〔(【引用サイトリンク】title=NRHP nomination for Framingham Reservoir No. 1 Dam and Gatehouse )〕 The dam measures in length, with an overfall area that is long. The embankments are wide, with a core of granite rubble laid in cement. The overfall area is topped with cut granite, and originally had wooden flashboards held in by pins. The gatehouse is a 1-1/2 story granite structure, designed by Boston city architect George Clough. Located at the southern end of the overfall, it houses the end of a conduit from Farm Pond, a pipe connecting this reservoir to numbers 2 and 3, and gates for channeling water either into the Farm Pond conduit or into the river. There are also flood gates and equipment for moving the dam's flashboards.〔 The dam and gatehouse were listed on the National Register of Historic Places in 1990.〔 ==See also== *Framingham Reservoir No. 2 Dam and Gatehouse *Framingham Reservoir No. 3 Dam and Gatehouse *Sudbury Aqueduct *National Register of Historic Places listings in Framingham, Massachusetts 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Framingham Reservoir No. 1 Dam and Gatehouse」の詳細全文を読む スポンサード リンク
