Hoover Dam Hoover Dam, originally known as Boulder Dam from 1933 to 1947, when it was officially renamed Hoover Dam by a joint resolution of Congress, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. The dam was named after President Herbert Hoover.
Framingham Reservoir No. 1 Dam and Gatehouse 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, which is also known as the Stearns Reservoir, 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 and were 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 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 Reservoir No. 1 is no longer maintained as a reserve water source, although it is still owned by the Massachusetts Water Resources Authority, successor to the Boston Water Board which oversaw its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.
