Hoover Dam Hoover Dam history and facts Check out our enormous list of facts on the Hoover Dam in Nevada, with pictures, videos and lots of fascinating details! The top 10 things you probably didn’t know about the Hoover Dam.
While Hoover Dam sits in the shadow of other magnificent structures like the Golden Gate Bridge and Eiffel Tower, it is still an engineering marvel built nearly a hundred years ago. History proves that no matter how modern our technology becomes, we will never be able to fully recreate the ambition, courage, and determination needed to build a stone bridge thousands of years ago. Yet the Hoover Dam remains a constant reminder that those same qualities never expire.
Hoover dam cost to build
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.
In 1998, a spillway failure severely damaged the dam’s main channel spillway, which serves to regulate uncontrolled flows from Lake Mead to prevent overtopping during periods of peak runoff or rapid snowmelt when there are high water demands from downstream users.[12] After several inspections revealed that the concrete lining of this spillway was badly deteriorated and thick deposits of silt had clogged its drains,[13] it was decided that an emergency repair job would be required before further damage could result in an uncontrolled release of water into Black Canyon below.[14]
The crisis prompted an overhaul of all Federal Bureau of Reclamation (USBR) dams in the United States, including those classified as “high hazard potential”, which were grouped into two categories: Category 1 “high hazard potential dams” must be inspected every 10 years

In terms of size and power, it is the largest dam in the United States, ahead of its nearest competitor, Grand Coulee Dam on the Columbia River (which has a larger reservoir capacity). When it was completed in 1935, it stood as the world’s largest concrete structure for over 50 years until it was surpassed by multiple other dams in China.[4] Currently, it is 3rd largest dam in world by volume.[5]
Hoover Dam History
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 idea for the dam was originally developed in 1895 by a former federal engineer named Arthur Powell Davis, who had made his reputation as a successful builder of dams in California and Oregon in the 1880s and 1890s. In 1928, Congress authorized its construction as part of a larger bill authorizing the development of the Colorado River for navigation purposes. The winning bid to build it was submitted by Rocky Mountain Power Company (a forerunner to Pacific Gas & Electric), whose chief engineer was Frank Crowe. It took five years to build using 6 million barrels (1,500,000 m3) of concrete poured into forms which were built at ground level in blocks weighing up to 90 tons each.[2]

The dam was controversially named after President Hoover, who had overseen its construction as Secretary of Commerce but played no role in supervising its construction or design; he had left office earlier in 1929 before its completion.[2] AfterHoovervacated his position as Secretary of Commerce in March 1933 because of term limits under the 22nd Amendment to the Constitution,[3] he continued to be involved with water resource development issues through an organization known as the National Committee for Unemployment Insurance (NCUI).[4] NCUIhad been renamed National Committee for Prevention of Unemployment (NCPU) by this time.[5]
In 1938 he founded The Hoover Institution on War, Revolution
Hoover Dam was built between 1931 and 1936 during the Great Depression. It was designed by the U.S. Bureau of Reclamation and constructed by the Six Companies consortium. It 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.
The dam is named for President Herbert Hoover. In 1928, Congress authorized the project in response to a severe drought affecting farmers in the West, and construction began soon after.
The dam was dedicated on September 30, 1935, by President Franklin D. Roosevelt, who called it a great engineering achievement and an outstanding monument to collaboration between government and industry.[2] The dam was listed on the National Register of Historic Places in 1983,[3] designated a National Historic Landmark in 1985[4] and as a UNESCO World Heritage Site in 1987.[5]
Herbert Hoover was an American mining engineer and politician who served as the 31st president of the United States from 1929 to 1933. A member of the Republican Party, he previously served as secretary of commerce under Presidents Warren G. Harding and Calvin Coolidge from 1921 to 1924
The 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 Nevada and Arizona. It was constructed between 1931 and 1936 during the Depression years of the administration of President Herbert Hoover.
Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full). The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The famous tourist destination Las Vegas Strip lies close to the dam.
The dam was declared a National Historic Landmark in 1985.[2] It is often known as “Boulder Dam”, because of its location in Boulder City, but its official name is “Hoover Dam”, after Herbert Hoover.
Hoover Dam was one of the largest engineering projects ever undertaken at the time of its construction. Its construction required five years, starting in 1931 and ending in 1935; three men died during its construction.[3] The concrete structure was built with 3.25 million cubic yards (2.4 million m³) of concrete,[4] and has an average thickness

The dam was authorized by the Boulder Canyon Project Act of 1928, which authorized the project and authorized funding. The act was controversial; it required the federal government to purchase 10,000 acres (40 km2) of land from Nevada and Arizona, and to compensate those whose property was taken with $75 million ($1 billion today). The final cost of the dam has been estimated at about $49 million dollars.[3] When completed, it created Lake Mead, an artificial lake covering 225 square miles (580 km2), with a capacity of 36 trillion U.S. gallons (140 trillion L) — enough water to cover New York City 11 feet deep.[4]
Hoover Dam, the world’s tallest dam, is an engineering marvel and a feat of modern construction. It took 5 years to build this concrete behemoth, which was built during the Great Depression. The dam was completed in 1936 and named after President Herbert Hoover who had started the project.
The dam is 726 feet high and 660 feet wide at its base. It is 660 feet thick at its center and contains 1,300,000 cubic yards of concrete. It has over 518 miles of pipe, enough to stretch from New York City to Los Angeles. The top of the dam is 2,100 feet above sea level!
Hoover Dam provides electricity for millions of people living in Southern California and Southern Nevada as well as Las Vegas. It also provides water for irrigation purposes and flood control for the lower Colorado River Basin states (Arizona, California, Colorado, New Mexico and Utah).

Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full).[5] The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi southeast of Las Vegas, Nevada. The dam straddles the border between Nevada and Arizona; it is only 18 ft (5 m) tall but has a length of 1,244 ft (379 m) and contains 7 million cubic yards (5 million cubic meters) of concrete.[6]
When the Hoover Dam was completed in 1936, it was the largest concrete structure ever built. It also created Lake Mead, the largest artificial lake in the United States.
The Hoover Dam is named after President Herbert Hoover, who authorized its construction during the Great Depression.
The dam was built to control the flow of Colorado River water into the Imperial Valley and prevent flooding in Mexico. Between 1931 and 1936, the Bureau of Reclamation spent $49 million on building this concrete behemoth.
The Hoover Dam stretches 1,244 feet long (379 m) and 726 feet high (221 m). It holds back more than 2 trillion gallons (7.6 trillion liters) of water behind its walls — enough water to fill Lake Michigan three times over!
