Building Of The Hoover Dam
When the construction of the Hoover Dam began in 1930, it became the largest, most expensive federally funded project in American history. 21,000 men toiled in sweltering heat for between $.50 and $1.25 a day to erect the 726-foot tall dam, the tallest in the world at that time. It took 4.3 million cubic yards of concrete to build the dam, power plant, and complementary components. The towering dam ranked as the world’s largest hydroelectric dam for 10 years from 1939 to 1949.
Even today, it supplies electricity to three separate states and generates roughly 4 billion kilowatt-hours (kWh) of hydroelectric power each year. Since its inception, the Hoover Dam experienced an identity crisis, a Nazi bombing plot, and conspiracy theories. Nevertheless, the dam keeps humming to this day.
