Metropolitan Water Commission is established.

Originally the Metropolitan Water District, it is created by the Massachusetts legislature to assume the operations of the Boston Water Works and adopts a plan by Frederick Stearns to construct a dam on the Nashua River in Clinton, Massachusetts. The commission oversees the district that initially includes 13 cities and towns and soon is expanded to 20 municipalities. It merges with the Metropolitan Sewerage Board in 1901 and the Metropolitan Park Commissions in 1919.*
