The Hoover Dam was built to irrigate and provide hydroelectric power to the states of California and Arizona. In addition, the Hoover Dam was built to control seasonal flooding of the Colorado River, which made settlement in the arid Southwest possible. The dam was built during the 1930s and was, at the time, one of the largest man-made structures.Continue Reading
In 1905, melting snow from the Rocky Mountains caused the Colorado River to flood parts of Nevada. After acres of farmland were destroyed, it became evident that the flow of the Colorado River needed to be restricted to allow settlers to remain in the area.
Plans for the dam began in 1922, although it was known at that time as the Boulder Canyon Project. The Black Canyon was chosen as the location of the dam. Construction on the dam began in 1930. Over 200 engineers and over 21,000 laborers worked on the construction. Workers from across the country arrived at the construction area and turned Las Vegas into a highly populated city.
The dam, originally called Boulder Dam, was dedicated on Sept. 30, 1935. Several years later, the dam was renamed and became known as the Hoover Dam to recognize President Hoover's oversight of the construction of the dam.Learn more about Architecture
As of July 2015, the water level in the Hoover Dam reservoir is at its lowest point ever, at just under 1075 feet. This level is 140 feet lower than its highest point, recorded in 1983.Full Answer >
According to the U.S. Bureau of Reclamation, the “official” number of fatalities in building the Hoover Dam is 96. Most were men who suffered “industrial fatalities,” such as drowning, falls from canyon walls and truck accidents. Not included were workers injured at the site, who died later from unreported complications.Full Answer >
According the United States Geological Survey, hydroelectric power offers clean energy without the emissions created by fossil fuels, but it is very location- and precipitation-dependent and can have major land and ecological effects. Hydroelectric dams can require major changes in natural waterways to function, and the dams may disrupt or displace humans and wildlife populations.Full Answer >
There are three basic different types of scaffolding: supported scaffolds, suspension scaffolds and manlifts or personnel hoists. Supported scaffolds are one or more platforms held up by items like poles and frames. Suspended scaffolds are platforms held by rope or some other overhead support.Full Answer >
