Hoover Dam In Las Vegas Nevada

Some years ago, I saw some pictures of a friend visiting one of the famous architecture in the world called Hoover Dam. I told myself, one day I will visit this place. It came true. Last May 2008, I finally had the chance to visit this incredible work of engineering. I can’t tell so much how it is made but here are some information I can share about Hoover Dam.

Hoover Dam, once known as Boulder Dam, 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. When completed in 1936, it was both the world’s largest hydroelectric power generating station and the world’s largest concrete structure. It was surpassed in both these respects by the Grand Coulee Dam in 1945. It is currently the world’s 38th-largest hydroelectric generating station.

One of the pictures I took during my visit in Hoover Dam last May 2008

* Construction period: April 20, 1931 – March 1, 1936
* Construction cost: $49 million ($736 million adjusted for inflation from 1936 to 2008
* Deaths attributed to construction: 112; 96 of them at the construction site
* Dam height: 726.4 ft (221.4 m), second highest dam in the United States. (Only the Oroville Dam is taller)
* Dam length: 1,244 ft (379 m)
* Dam thickness: 660 ft (200 m) at its base; 45 ft (14 m) thick at its crest.
* Average flow release: 22,000 cfs
* Concrete: 4,360,000 cu yd (3,330,000 m3)
* Maximum electric power produced by the water turbines: 2.08 gigawatts
* Approximate power output: 4,000,000,000 kW·h (1.4×1010 MJ) per year (i.e. $200 million at $0.05 per kWh)
* Traffic across the dam: 13,000 to 16,000 people each day, according to the Federal Highway Administration
* Lake Mead (full pool)
o area: 157,900 acres (63,900 ha), backing up 110 mi (180 km) behind the dam.
o volume: 28,537,000 acre feet (35.200 km³) at an elevation of 1,221.4 ft (372.3 m).
* With 8 to 10 million visitors each year, including visitors to Hoover Dam but not all traffic across the dam, the Lake Mead National Recreation Area is the fifth busiest National Park Service area. wikipedia
