james the lake was made when they built the Hoover Dam . the Lake is 247sq miles ( 460sq km )
The building of the dame was the start of every one going there for camping & of course all the water sports . It was also the start of the the legalizing of the red light business .
A fine view of the lake. It is a hard lake to photograph as it covers so wide an area, but its depth is quite shallow as the land it sits upon is mostly former flat desert. Actually, the lake is rather small, now. Las Vegas has rapidly grown in the past 3 decades and draws almost all its water from the lake. So much that the Federal water authority that distributes and divides the Colorado river water that travels down to Hoover dam between Nevada, Utah, Arizona, & California has placed a limit on how much Las Vegas can now draw. As a result the city is in a constant state of water rationing. I have family there who says the water pressure in the city pipes is so low that the water barely drips out of the faucets. Interestingly, though the city's humidity has dramatically risen in the last 30 years because of all the fountains built at the casinos and hotels. A very strange situation for a city built in the desert next to a man made lake. You can see how much the lake's surface has fallen in your photo. The little island tops of green foliage are far above the lake's surface.
