The wary retiree, . . .if indeed anyone will be able to retire in the near future, . . . might consider the source of his drinking water if he were to relocate to Las Vegas.
"Lake Mead, the man-made reservoir that supplies 90 percent of the water for 2 million people in the Las Vegas area, has been reduced by drought to the lowest level since it was filled in 1937, according to the federal government.
The lake’s surface, which reached a record high of 1,225 feet above sea level in July 1983, is now at about 1,083 feet, according to the bureau. If the level drops below 1,050 feet, one of the two intakes that feed water to Las Vegas will become inoperable. At 50 feet lower, the other would fail. Since 2008, contractors have been boring through rock to create a third conduit to draw water from as low as 860 feet. [This effort has cost more than expected [DUH !], so recently the project was modified to have the "third conduit" just intersect the second, . . . with an option to redirect the third conduit to a lower elevation if necessary later, . . . maybe. - DD]"
