[edit]DescriptionHoover Dam (7 Sept 08) (3053712554).jpg |
Las Vegas obtains 90-percent of their water from Lake Mead. They're spending $2-billion for a lower syphon. The Middle of the dam is the Nevada-Arizona border. Maximum electric power produced by the water turbines: 2.08 gigawatts Approximate power output: 4 billion KWh per year (i.e. $200 million at $0.05 per kWh) Source: <a href="http://en.wikipedia.org/wiki/Hoover_dam#Statistics" rel="nofollow">Wikipedia, Hoover Dam</a>. <a href="http://www.arachnoid.com/NaturalResources/index.html" rel="nofollow">Historical Graph of Lake Mead Water Levels</a> Updated every month. By July 2009, the water is expected to decline below the 1965 level, just 17 feet above the 1,075-foot elevation that would trigger the first shortage declaration under a sweeping interstate pact signed in December 2007.
