Around 16,000 men and women, with an average of 3,500 and a maximum of 5,218. The average monthly payroll was $500,000. Approximately 112 people died altogether, 96 of them died on the actual construction site.

The Colorado river flows through the grand canyon which is very big. to be exact the Colorado river is 1,450 miles long!

In the event of such a disaster, the water would gush downstream. That would cause widespread loss of life and property, but Las Vegas is not in the path and would not be directly affected.

The answer there is more pressure on smaller dams which creates MORE electricity.

Sorry but that makes no sense. The electricity generated depends on rate of flow and head available, not on dam size. In fact the higher the dam the greater the head (depth hence water-pressure at the turbine), though this can be increased still further by piping the water to a power-station situated further down the valley instead of at the dam foot.

A more useful advantage of a smaller dam is its smaller environmental effect.

Let's say the Hoover dam broke. This is difficult to imagine, given its thickness. No conventional bomb would have an effect on a dam like this. It is difficult to imagine even a nuclear bomb having an effect, unless it was an extremely powerful one and it were inside the dam at the time of explosion. But let's say that some sort of tremendous earthquake or an asteroid strike or some other natural disaster were to somehow crack it in halves. The first thing that would happen is that 10 trillion gallons of water would move as quickly as it could out of the lake and down the river in a huge tsunami of water. The Hoover dam is located in a desert area that is not hugely inhabited below the dam, but there are still some sizeable populations. Lake Havasu City, population 40,000, is about the biggest town in the United States along the river. Bullhead city, population 30,000 is also close to the dam. Needles, California and Laughlin, Nevada all have populations of around 10,000 people as well. Damages to the dam Where the water would do immense damage is in the lakes below Hoover dam. It turns out that below Hoover dam is another large lake called Lake Mohave, which is held in place by Davis dam, and below that is Lake Havasu, held in place by Parker dam. These are smaller lakes and smaller dams. For example, Lake Havasu only holds about 200 billion gallons of water. As the water released by the Hoover Dam moved through these two lakes, it would likely destroy them and their dams as well. That's where the real impact would be felt, because these lakes affect a huge number of people. The water in them produces hydroelectric power, irrigates farmland and supplies drinking water to cities like Los Angeles, Las Vegas, Phoenix and San Diego. The Hoover dam produces roughly 2,000 megawatts of power. Davis and Parker dams produce less, but together they might all produce 3,000 megawatts. That represents about one half of one percent of the total electrical power produced in the United States. If you eliminated a sizable amount of generating capacity like that, especially in that area of the country (near Los Angeles and Las Vegas, for example), it would definitely cause problems. The destruction of irrigation water supplies would also have a huge effect on farming in the region. Farmers in the Imperial Valley get most of their water from the Colorado River, and these irrigation systems would collapse. Prior to irrigation, the Imperial Valley was a barren desert. Today it is the home of more than half a million acres of farmland and produces more than a billion dollars in fruits and vegetables every year. There would be large effects as well from the loss of drinking water. For example, Las Vegas gets 85 percent of its drinking water from Lake Mead -- the lake behind Hoover dam. With the loss of water and the loss of power, Las Vegas would become uninhabitable, and that would displace 1.5 million residents and empty more than 120,000 hotels rooms and the casinos, bringing the multi-billion-dollar gambling industry in this city to a halt.

giving a lot of work

You should go do the Power Point tour. I think that's what its called. I've done it before and it is very intresting.

Around 10 Years.... The concrete used in this could build a highway fromLosAngeles to New York

Dams are typically built to retain water. Some manage or prevent water flow into certain areas (dikes). Dams are also built to be used for hydropower/pumped-storage hydroelectricity to provide energy.

The Hoover dam is rectangular and convex(bends out)

Colorado River.

Hoover Dam was built in the 1930s to provide electricity for the southwest U.S. and to prevent the wild Colorado River from flooding. Hoover Dam is about 380 m wide and is about 221 m high. Assume that Hoover Dam can be approximated by slab geometry with a width of 380 m (W). What is the total force (newtons) on the dam face if the water level from Lake Mead (holding basin for Hoover Dam) is 207 m? Assume the density of water in Lake Mead is 1000 kg/m3. (Hint: you should be able to do this problem without doing an integral. Ask yourself, how does pressure vary with depth along the wall of the dam? Therefore, at what depth will the pressure equal its average over the whole face of the dam?) its not an answer bt its a question you can think bout cos it involves physics

A key unit on the Colorado , the dam is a major supplier of hydroelectric power and provides for flood control, river regulation, and improved navigation.

Many reasons. It's massive size, the fact that it supplies much of the Nevada (including Las Vegas) region with water, it was built during the Great Depression and provided many with jobs, and also because of the horrid fact that some men helping to build it were cemented over after they fell.

6000000000 volts

that really is a loaded question. shortly after the dam was built, large power companies started selling or trading energy. in theory, the power generated from the hoover dam could be used anywhere, most likely in the US but its not a stretch to say that some would be transfered as far as the east coast or canada/mexico.

Hoover Dam gave men jobs. It was built during the depression and thousands of men and their families came to work. It took less than 5 years and today it is a national historic landmark. Mount Rushmore took 14 years to finish and was done by Gutzon Borglum. Today 3 million people visit the monument. It cost 989,992.32 to build and 90% of the heads are carved with dynamite. To work on it he needed men who could work in stone, dynamite, work with jackhammers, and other equipment hanging over the side of a mountain. The workers even had a baseball team.

Colorado River

There were 112 deaths associated with the construction of the dam, not included in the official fatalities number were 42 deaths that were recorded as pneumonia. Workers alleged that this diagnosis was a cover for death from carbon monoxide poisoning, brought on by the use of gasoline-fueled vehicles in the diversion tunnels, and a classification used by the Six Companies to avoid paying compensation claims.

The Hoover Dam produces approximately 2 gigawatts when running fully, so around 700,000 homes.
