Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada. 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.
The dam was controversially named after President Hoover despite his involvement in its construction being minimal; he had been instrumental in authorizing funding for its precursor, the Boulder Canyon Project Act, through Congress but had little to do with planning or construction.[2]

The dam was historically significant as one of the largest hydraulic engineering projects ever undertaken and its initial completion was celebrated as a great achievement in American engineering.[citation needed] However, it has since generated some controversy due to its impact on the natural environment and its enormous cost overruns.[1]
Cost to build hoover dam
The Hoover Dam is a hydroelectric dam that was built in the Black Canyon of the Colorado River between Arizona and Nevada. It was constructed from 1931 to 1936 and was named after President Herbert Hoover. The dam provides water and electricity for people living in the surrounding areas.
The Hoover Dam is 726 feet tall, or 186 meters. It is 750 feet thick at its base, or 226 meters wide. The top of the dam contains water pipes that are 18 feet in diameter, each containing 28 separate pipes that carry water from Lake Mead to Las Vegas and other areas.
The Hoover Dam took five years to build and cost $49 million dollars. It was built by 21,000 men who worked on it every day except Christmas Day and New Year’s Day. Eight hundred workers died during construction due to harsh conditions such as heat, exhaustion and accidents like falling rock (http://www.hooverdam100thanniversary.com/history/).
The Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the US 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.
The dam was authorized by Congress in 1928 as part of a larger bill authorizing major flood control works throughout the country. The bill passed after considerable lobbying by California Congressman Phil Swing (who represented the Imperial Valley) and by local business interests. The eventual bill included funding for several other projects in addition to the Hoover Dam: San Gabriel Dam, Parker Dam, Davis Dam, Friant Dam and Laguna Diversion Dam.[2] The total cost of building all six dams came to $408 million.[3]
The Hoover Dam, or Boulder Dam as it was originally called, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada. 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.
The dam was widely praised for its innovative design and sturdy construction. At the time of its completion, it was both the world’s largest electric-power generating station and largest concrete structure in volume () by total lift . The final cost to build the dam is estimated to be $165 million ($2 billion in 2008 dollars).
The first official mention of a proposed dam for Los Angeles occurred as early as 1853 when William Mulholland wrote about building a dam “at some point near where now stands” under his pen name “The Father of Waters”. The idea remained dormant until 1900 when Mulholland proposed using water from Owens Valley to irrigate crops

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.
The dam was authorized by the Flood Control Act of 1928 and its construction was financed by the Federal Emergency Relief Administration, the Bureau of Reclamation, and later by its successor agency, the United States Bureau of Reclamation (USBR). The dam was built to contain floods, provide irrigation water and produce hydroelectric power.
The famous 726-foot high structure stands just over 200 feet above the riverbed at its highest point when empty (it can fill up to 1/2 mile deep) and is made from millions of cubic yards (m3) of concrete reinforced with steel rods that were poured into place using buckets suspended from cables attached to cranes; more than 2 million cubic yards were used for each tower alone!
Hoover Dam was built during the Great Depression as a way to create jobs and provide electricity and water to the Southwest.
The dam was designed by Bureau of Reclamation architect Gordon B. Kaufmann and structural engineer Hal Griggs in 1931, and construction began in 1931. The project was completed in 1936 and officially dedicated on September 30, 1935 by President Franklin D Roosevelt. It was named for President Herbert Hoover, who had overseen the start of its construction while he was President from 1929 to 1933.
The dam cost $49 million ($611 million today) at the time of construction, with most of the materials coming from nearby Las Vegas, Nevada; it has since required $700 million more in maintenance and repairs.
Hoover dam facts
The Hoover Dam was constructed by thousands of men working under dangerous conditions. More than 100 people died during construction, including at least 19 workers who were killed in a major accident on September 20, 1935. The accident occurred when a section of concrete fell from a cofferdam and hit an intake tower below, causing it to collapse into the Colorado River.
Longest Dam in the United States
The Hoover Dam is 726 feet tall (the second tallest structure in Nevada) and 1,244 feet long (the longest dam in the United States). It’s also 1.25 miles wide at its base and 660 feet across at its crest. The dam contains 7.5 million cubic yards of concrete (enough to build another Hoover Dam), which help make it one of the largest man-made structures on Earth.
How Long Did It Take to Build Hoover Dam?
Construction on the Hoover Dam began on March 11, 1931, but didn’t finish until 1936 — two years later than originally planned due to problems with concrete quality control and construction scheduling issues caused by funding shortfalls brought on by the Great Depression. The project cost $49 million dollars (or $1 billion adjusted for inflation
How many people died building the Hoover Dam?
The Hoover Dam was built between 1931 and 1936 during the Great Depression. During construction, 112 workers died. The project included a total of 18 deaths from falls and another 16 from heat exhaustion or drowning.
How long did it take to build the Hoover Dam?
Construction of the Hoover Dam started on March 11, 1931. It took five years to build and 34 men lost their lives during construction, but not all at once. The dam was officially dedicated on September 30, 1935 by President Franklin D. Roosevelt, who personally dedicated the dam with his wife Eleanor and son James along with members of Congress and other invited guests. It took 18 months to fill Lake Mead after completion of the dam in 1936. In addition to the deaths during construction, there were also three workers killed while performing maintenance on the dam years later in 1976 and 1984 when they fell off an inspection platform that wasn’t meant for humans to stand on anyway (it was built for equipment).
Hoover Dam was built during the Great Depression as a way to provide jobs and produce electricity. It took 5 years and 21 million pounds of dynamite to build, and it cost an estimated $49 million.
The dam is named after President Herbert Hoover because he signed legislation authorizing its construction.
The dam’s builders had to overcome the problem of uneven ground below the dam site by building 1,480 concrete blocks and placing them on top of each other using hydraulic jacks. They also had to deal with extreme heat and cold, as well as flash floods caused by sudden rainstorms.

The U.S. Bureau of Reclamation owns and operates the dam, which provides water for both domestic and municipal uses as well as hydroelectricity for power generation.[1] The dam’s reservoir is called Lake Mead, whose waters extend upstream to central Nevada, providing water for the states of Arizona, California, and Nevada.[2] The dam is located near Boulder City,[3] Nevada,[4] about 25 mi (40 km) southeast of Las Vegas, Nevada.[5][6]
In 2009 an estimated 7 million people visited the dam.[7] The dam has been featured in many forms of media since its construction in the 1930s such as in books,[8] television shows[9]
