Built in the Black Canyon of the Colorado River, Hoover Dam is located at the border of Nevada and Arizona, in the United States, its purpose has been to regulate the waters of the Colorado River. Lake Mead, the largest reservoir of the world, helps regulate the water during floods and supply during periods of drought. The packages of Hoover Dam Tours include various options to view the Plant alone or the Plant along with the inspection tunnels.
While the dam stands majestically, inviting the guests to view the beauty and the magnificent technology, the physical dimensions and features are a wonder in themselves. It stands to a height of 726.4 feet, is 1,224 feet long and 660 feet thick at the base. At the time of completion in the year 1935, it was the largest concrete structure and the largest electric-power generating station in the world, until Grand Coulee Dam took over in 1945. Lake Mead remains the largest largest reservoir of the world, with a surface area of 146,000 acres. The storage capacity of the dam is 9.2 trillion gallons of water.
It weighs 6.6 million tons and was built with about 4,360,000 cubic yards of concrete. Cooling tubes were used shape up the concrete, which was then an unproven technology, yet proved to be a success. About 16,000 people were employed for the construction of the dam, with over 3,500 working at a given time. Total cost of the construction of the Dam was $49, 000,000. Construction work was started in the year 1931 and ended in 1935, two years ahead of the scheduled time.
There are 17 generators and have the capacity to produce 2,000 megawatts of electricity, supplying to more than 750,000 people, in the States of Nevada and Arizona and a large part of Southern California. It supplies water to over 25 million people in the southwest United States.
With so many huge numbers and technology associated with the dam, it is not a surprise that Hoover Dam is one of the seven modern engineering wonders by the American Society of Civil Engineers (ASCE), with over 4,000 tourists coming everyday to marvel at its beauty and structural wonder.
