The Colorado River is an example of a large wash?

Certainly, it is just the part that is covered in water. The Hoover Dam bloks the Colorado river. Under Lake Mead behind the dam is the extension of the Grand Canyon.

Technically, Arizona, California, and Nevada. The allocation specifies that Arizona gets about a fifth, Nevada gets about a fourth, and the rest (a bit over half) goes to various cities and entities in California.

However, because the US electrical grid is so interconnected, in practice it's difficult to tell where the energy actually goes.

The Platte River has its beginnings in the Rocky Mountains on the eastern slope. The word "Platte" is the French word for "flat". It is a slow meandering river as it winds it way east.

that's

77 people died in building the original high dam.

4 more people died in the building of the Third Power Plant at Grand Coulee Dam in the 70's and early 80's.

The Hoover Dam was constructed to control flooding on the Colorado River and to generate electricity. As part of that function, it created a large lake that serves as a water reservoir and a recreational facility.

It's very difficult to answer questions like this because of the way the US power grid works. Power producing sites put power on the grid, and power consuming sites take power off the grid, and it's not really possible to track exactly what goes where. Think of it this way: the power grid is a big barrel full of water. Las Vegas has a pipe coming out of the barrel, and Hoover Dam has a pipe going into the barrel, but there are many other pipes coming out and going in. Finding out if a particular drop of water flowing through the Las Vegas pipe came from the Hoover Dam pipe would be difficult. The power grid is actually worse than that, because we could theoretically put some dye in the water, but we can't do that with power; an electron is an electron is an electron. That said: Las Vegas actually does not get much of its power from Hoover Dam, since the electric company serving Las Vegas is NV Energy, which owns its own power plants and does not operate the generators at Hoover Dam. NVE's own website states that 70% of their power generation for southern Nevada comes from natural gas fired plants, so at most 30% of Las Vegas' power would come from Hoover Dam (and most likely much less than that). Also, the US Bureau of Reclamation (the agency that operates the generators at the dam) does not list Las Vegas as a recipient of the power generated. They do list the State of Nevada in general (which gets about 23% of the power generated by the dam), but the only specific city in Nevada that's listed is Boulder City, NV.

Hears the short answer Lake Mead. :)

due to a very wet winter the water level in lake mead rose to flood level, the camp grounds and launching ramps where all under water. this took place in 1983

Yes, it is a very popular tourist destination.

8 miles

There seems to be no deaths occurring during concrete pouring, and contrary to all the rumours there are no workers buried in the dams walls.

Overall, the death toll for the dam was 96 workers.

45 square miles

Boulder City (Nevada).

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!
