Hoover Dam by a joint resolution of Congress, is a concretearch 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 1. Great Depression and was dedicated on September 3. 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. Since about 1. Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1. 92. 8, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned over the dam to the federal government on March 1, 1. 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 3. Las Vegas, Nevada. The dams generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction nearly a million people tour the dam each year.

BackgroundeditSearch for resourceseditAs the United States developed the Southwest, the Colorado River was seen as a potential source of irrigation water. An initial attempt at diverting the river for irrigation purposes occurred in the late 1. William Beatty built the Alamo Canal just north of the Mexican border the canal dipped into Mexico before running to a desolate area Beatty named the Imperial Valley. Though water from the Imperial Canal allowed for the widespread settlement of the valley, the canal proved expensive to maintain. After a catastrophic breach that caused the Colorado River to fill the Salton Sea, the Southern Pacific Railroad spent 3 million in 1. Federal Government. Even after the waterway was stabilized, it proved unsatisfactory because of constant disputes with landowners on the Mexican side of the border. River view of the future site of Hoover Dam, circa 1. As the technology of electric power transmission improved, the Lower Colorado was considered for its hydroelectric power potential. In 1. 90. 2, the Edison Electric Company of Los Angeles surveyed the river in the hope of building a 4. W. However, at the time, the limit of transmission of electric power was 8. Edison allowed land options it held on the river to lapseincluding an option for what became the site of Hoover Dam. In the following years, the Bureau of Reclamation BOR, known as the Reclamation Service at the time, also considered the Lower Colorado as the site for a dam. Service chief Arthur Powell Davis proposed using dynamite to collapse the walls of Boulder Canyon, 2. The river would carry off the smaller pieces of debris, and a dam would be built incorporating the remaining rubble. In 1. 92. 2, after considering it for several years, the Reclamation Service finally rejected the proposal, citing doubts about the unproven technique and questions as to whether it would in fact save money. Planning and agreementsedit. Sketch of proposed Boulder Canyon dam site and reservoir, circa 1. In 1. 92. 2, the Reclamation Service presented a report calling for the development of a dam on the Colorado River for flood control and electric power generation. The report was principally authored by Davis, and was called the Fall Davis report after Interior Secretary Albert Fall. The Fall Davis report cited use of the Colorado River as a federal concern, because the rivers basin covered several states, and the river eventually entered Mexico. Though the Fall Davis report called for a dam at or near Boulder Canyon, the Reclamation Service which was renamed the Bureau of Reclamation the following year found that canyon unsuitable. One potential site at Boulder Canyon was bisected by a geologic fault two others were so narrow there was no space for a construction camp at the bottom of the canyon or for a spillway. The Service investigated Black Canyon and found it ideal a railway could be laid from the railhead in Las Vegas to the top of the dam site. Despite the site change, the dam project was referred to as the Boulder Canyon Project. With little guidance on water allocation from the Supreme Court, proponents of the dam feared endless litigation. A Colorado attorney proposed that the seven states which fell within the rivers basin California, Nevada, Arizona, Utah, New Mexico, Colorado and Wyoming form an interstate compact, with the approval of Congress. Such compacts were authorized by Article I of the United States Constitution but had never been concluded among more than two states. In 1. 92. 2, representatives of seven states met with then Secretary of Commerce. Herbert Hoover. Initial talks produced no result, but when the Supreme Court handed down the Wyoming v. Colorado decision undermining the claims of the upstream states, they became anxious to reach an agreement. The resulting Colorado River Compact was signed on November 2. Legislation to authorize the dam was introduced repeatedly by two California Republicans, Representative Phil Swing and Senator Hiram Johnson, but representatives from other parts of the country considered the project as hugely expensive and one that would mostly benefit California. The 1. 92. 7 Mississippi flood made Midwestern and Southern congressmen and senators more sympathetic toward the dam project. On March 1. 2, 1. St. Francis Dam, constructed by the city of Los Angeles, caused a disastrous flood that killed up to 6. As that dam was a curved gravity type,1. Black Canyon dam, opponents claimed that the Black Canyon dams safety could not be guaranteed. Congress authorized a board of engineers to review plans for the proposed dam.
