    Hoover Dam stores water that irrigates 2 million acres, not only in the rich farm fields of Southern California’s Imperial Valley, but across the state line in Arizona. Hoover Dam, formerly called Boulder Dam, dam in Black Canyon on the Colorado River, at the Arizona - Nevada border, U.S. Constructed between and , it is the highest concrete arch dam in the United States. It impounds Lake Mead, which extends for miles ( km) upstream and is one of the largest artificial lakes in the world.

The dam is used for flood and silt control, hydroelectric poweragricultural irrigationand domestic water supply. It is also a major sightseeing destination, with some seven million visitors a year, almost one million of whom go on tours through the dam.

    Hoover Dam is feet metres high and 1, feet metres long at the crest. It contains 4, cubic yards 3, cubic metres of concrete. Four reinforced-concrete intake towers located above the dam divert water from the reservoir into huge steel pipes called penstocks.

    The water, after falling some feet metres through the pipes to a hydroelectric power plant in the base of the dam, turns 17 Francis-type vertical hydraulic turbineswhich rotate a series of electric generators that have a total power capacity of 2, megawatts. Nearly half of the generated electric power goes to the Metropolitan Water District of Southern California, the city of Los Angelesand other destinations in southern California; the rest goes to Nevada and Arizona.

    The dam, power plant, and reservoir are owned and managed by the U. Hoover Dam is named in honour of Herbert Hooverthe U.

Although legislation passed by Congress in officially named the dam for Hoover, officials in the succeeding administrations of Franklin D.

    Deconstructing History: Hoover Dam

    Jan 26,  · The Hoover Dam is, as you can see by the name, a dam. It dams the Colorado River, which forms the border between Arizona and Nevada. At that time it was decided to build the Hoover Dam, because the Colorado River rose too much in Winter during the snowmelt. The Colorado River flooded parts of the country and residents were threatened. Mar 10,  · Hoover Dam is located approximately 30 miles southeast of Las Vegas, on the Nevada-Arizona border. The Dam does not have a street address, so directions are provided below. Also, visitors with GPS navigators can use the coordinates: N , W to locate the site. Sep 28,  · funslovestory.com Editors In the early 20th century, the U.S. Bureau of Reclamation devised plans for a massive dam on the Arizona-Nevada border .

    In the early 20th century, the U. Bureau of Reclamation devised plans for a massive dam on the Arizona-Nevada border to tame the Colorado River and provide water and hydroelectric power for the developing Southwest. Construction within the strict timeframe proved an immense challenge, as the crew bored into carbon monoxide-choked tunnels and dangled from heights of feet to clear canyon walls.

    The largest dam in the world at the time of its completion in , this National Historic Landmark stores enough water in Lake Mead to irrigate 2 million acres and serves as a popular tourist destination. At the turn of the 20th century, farmers sought to divert the Colorado River to budding Southwestern communities via a series of canals. When the Colorado broke through the canals in , creating the inland Salton Sea, the job of controlling the raging river fell to the U.

    Bureau of Reclamation. Bureau director Arthur Powell Davis in outlined a plan before Congress for a multipurpose dam in Black Canyon, located on the Arizona- Nevada border. Named the Boulder Canyon project, after the original proposed site, the dam would not only control flooding and irrigation, it would generate and sell hydroelectric power to recoup its costs. Secretary of Commerce Herbert Hoover brokered the Colorado River Compact to divide the water proportionally among the seven states, but the legal wrangling continued until outgoing President Calvin Coolidge authorized the Boulder Canyon Project in December As the Great Depression unfolded, hopeful laborers descended on Las Vegas and set up camp in the surrounding desert for the chance to work on the project.

    Those who were hired eventually moved to Boulder City, a community specifically built six miles from the work site to house its employees. Meanwhile, the U. The first difficult step of construction involved blasting the canyon walls to create four diversion tunnels for the water. Facing strict time deadlines, workers toiled in degree tunnels choked with carbon monoxide and dust, conditions that prompted a six-day strike in August The second step of involved the clearing of the walls that would contain the dam.

    Suspended from heights of up to feet above the canyon floor, high scalers wielded pound jackhammers and metal poles to knock loose material, a treacherous task that resulted in casualties from falling workers, equipment and rocks.

    Meanwhile, the dried riverbed allowed for construction to begin on the powerplant, four intake towers and the dam itself. Cement was mixed onsite and hoisted across the canyon on one of five ton cableways, a fresh bucket capable of reaching the crews below every 78 seconds.

    Offsetting the heat generated by cooling concrete, nearly miles of pipe loops were embedded to circulate water through the poured blocks, with workers continually spraying the concrete to keep it moist. As the dam rose, block by block, from the canyon floor, the visual renderings of architect Gordon Kaufmann took form.

    Electing to emphasize the imposing mass of the structure, Kaufmann kept the smooth, curved face free of adornment. The powerplant was given a futuristic touch with horizontal aluminum fins for windows, while its interior was designed to pay homage to Native American cultures.

    With the body of water that would become Lake Mead already beginning to swell behind the dam, the final block of concrete was poured and topped off at feet above the canyon floor in Approximately 5 million barrels of cement and 45 million pounds of reinforcement steel had gone into what was then the tallest dam in the world, its 6.

    Altogether, some 21, workers contributed to its construction. Hoover Dam fulfilled the goal of disseminating the one-wild Colorado River through the parched Southwest landscape, fueling the development of such major cities as Los Angeles, Las Vegas and Phoenix. Capable of irrigating 2 million acres, its 17 turbines generate enough electricity to power 1.
