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.
How much did it cost to build hoover dam
The U.S. government spent $49 million on the dam’s construction from 1931 to 1936, according to the Bureau of Reclamation. The project eventually cost $165 million when inflation is taken into account.
In 2013 dollars, that works out to about $2 billion for a time when modern construction techniques made it possible to build such a massive structure in just five years — an astonishing feat of engineering that remains one of America’s greatest public works projects to this day.
What does the Hoover Dam symbolize?
The Hoover Dam is one of the most famous public works projects in American history because it symbolizes both an iconic piece of 20th century infrastructure and a major step forward in American industrial development during the Great Depression. It was also Franklin Roosevelt’s favorite project during his tenure as president, according to PBS NewsHour host Judy Woodruff, who visited the dam with her father during its construction as a child and wrote about her experience in her book “My Father’s Daughter.”
Hoover Dam is one of the most famous and well-known landmarks in the United States of America. 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. 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 – who had a role in its authorization – by a joint resolution of Congress.
The dam impounds Lake Mead, an artificial lake covering behind it, which has been used to supply water to Las Vegas since it opened in 1936. The reservoir is one of the largest man-made lakes in the United States, about long with a capacity of . The dam is high from foundations to top with two arches higher than . Each arch measures high from base to crest (top) above bedrock at streambed.[10]
The concrete structure contains 2,500,000 cubic yards (1,900,000 m3)
The Hoover Dam, located in the Black Canyon of the Colorado River, is a one-of-a-kind structure. It’s a concrete arch-gravity dam, which means it uses the weight and force of water to keep its walls intact. The Hoover Dam stands more than 700 feet tall, with a base that’s almost 1,200 feet wide.
The dam was built between 1931 and 1936 by the U.S. Bureau of Reclamation as part of a public works program during the Great Depression. Construction required nearly 5 million cubic yards of concrete and 55 million pounds of steel rebar. It took more than 20,000 workers to complete construction on time — an amazing feat considering they had to work around floods and heavy rains throughout the summer months.
The Hoover Dam was named after former President Herbert Hoover, who oversaw much of the planning for the project during his tenure as secretary of commerce under President Calvin Coolidge (1923–29). Though President Hoover was not in office when Congress authorized funds for construction at Boulder Canyon in 1928, he became associated with the project because he had been instrumental in securing funding from Congress through his connection with Senator Edward Pecora (D-N.J.).
In 1933 President
Hoover Dam was built by the Bureau of Reclamation, and named in honor of President Herbert Hoover. Construction began on September 17, 1931, and was completed in 1936. The dam is located on the border between Nevada and Arizona, about 30 miles southeast of Las Vegas.
Hoover Dam is a concrete arch-gravity dam that blocks the Colorado River and impounds Lake Mead, one of the largest man-made lakes in the United States. It stands 726 feet (221 m) high from its deepest foundation to its crest, above the low point of the dam; at its base it is 45 feet (14 m) thick. The volume of concrete used for construction is over 3 million cubic yards (2.4 million m³), averaging 57 cubic yards (46 m³) per minute for the concrete placement of a wall up to 811 feet (250 m) high and 4-1/2 feet (1.4 m) thick at its base when using a 300-foot (91 m) crane. The reservoir created by the dam is 1,350 square miles (3,500 km²).

The Hoover Dam, located on the border of Arizona and Nevada, was built by the federal government in the 1930s to provide electricity for the Southwest United States. The dam’s construction took over five years, from 1931 to 1936, and cost about $49 million.
The Hoover Dam is named after Herbert Hoover, who was president when it was built. It’s also known as Boulder Dam or Boulder Canyon Dam.
The Hoover Dam provides electricity to millions of people who live in California, Arizona and Nevada. The dam also helps control floods along the Colorado River and stores water for release during dry seasons.
The dam is 726 feet high at its crest (the point where water flows over) and 550 feet thick at its base. It’s 660 feet wide at its top and covers an area of 1,244 acres (567 hectares).

How long did it take to build the hoover dam?
Construction began on March 11th 1931 and ended on November 1st 1936; this means that it took around 5 years to complete construction of this huge project!
Hoover Dam History
The first known inhabitants of what would become Arizona were members of the Ancient Pueblo People who migrated into the region sometime between AD 400 and 800. The Hohokam culture occupied central Arizona in the first millennium CE before being replaced by another group known as the Mogollon in 1250 CE. Most archaeologists speculate that these migrations took place because of changes in climate caused by global cooling or increased volcanic activity which affected their ability to grow crops in

The Hoover Dam is an engineering marvel that has withstood many tests of time. Here are some interesting facts about this amazing structure:
What does the Hoover Dam symbolize?
The Hoover Dam is more than just a dam; it represents many things to many people in America. It’s a symbol of American ingenuity during tough economic times when millions were out of work and desperate for jobs. It’s also considered an engineering wonder that demonstrates what Americans can do when they set their minds to solving problems.
How long did it take to build the Hoover Dam?
Construction started in 1931 and took 5 years to complete! There were two periods where work stopped completely: from 1934-1935 when a strike occurred at the site; and from 1937-1938 when there was insufficient funding due to
Hoover Dam Facts and Statistics
Hoover Dam was constructed between 1931 and 1936 by the Bureau of Reclamation. The construction project cost $49 million and required 5,251,947 pounds of dynamite.
The Hoover Dam is located on the Colorado River in Black Canyon, Arizona, between Las Vegas and Phoenix. The dam was built across the Colorado River at an elevation of 1,244 feet above sea level. The dam is 726 feet high from its base to the top of its crest. The structure is 660 feet long and contains more than 2 million cubic yards of concrete (1 cubic yard = about 1 ton).

The Black Canyon and nearby Boulder Canyon were among the sites investigated for the dam site, but ultimately Hoover was chosen for its low sandstone cliffs, which were considered stable; this led to its use as a model for many other dams.[4] In 1928 Senator Pat McCarran helped gain federal funding for the dam.[5] In 1930 there were growing concerns about how indigenous populations would be affected by the reservoir that would be created by a dam in Black Canyon.[6]
In March 1931 President Herbert Hoover signed into law an act authorizing the construction of Hoover Dam as part of the Boulder Canyon Project,[7] which authorized numerous dams along major rivers in western states.[8] His wife, Lou Henry Hoover (18741944),[9][10][11][12][13]

Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full).[1] 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.[2] The dam’s generators provide power for public use; about 4 billion kilowatt-hours per year.[3] Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year.[4]
