An initial attempt at diverting the river for irrigation purposes occurred in the late 1890s, when land speculator 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.
Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam for President Herbert Hoover by a joint resolution of Congress in 1947. Since about 1900, the 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 [power].
After a catastrophic breach that caused the Colorado River to fill the Salton Sea, the Southern Pacific Railroad spent $3 million in 1906–07 to stabilize the waterway, an amount it hoped in vain would be reimbursed by the federal government.
In 1928, Congress authorized the project.
It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D.
The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction of the dam in early 1931.

Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule. Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full).

Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened. == Background == === Search for resources === As the United States developed the Southwest, the Colorado River was seen as a potential source of irrigation water.
