Lake Powell Down to 22% Full

Washington Post:  "Water levels in the nation’s second-largest reservoir dropped to a record low last week, raising the alarm that major changes are on the way for the seven states — and millions of Americans — relying on that system, experts say.

"Lake Powell, a man-made reservoir that sits along the Colorado River on the Arizona-Utah border, generates electricity for about 4.5 million people. It is also a key part of the Colorado River Basin system, which supplies water to more than 40 million people. As of last week, its water levels fell to 3,522 feet above sea level, which is the lowest seen since the structure was filled in the 1960s. It’s now just 22 percent full, and unprecedented cuts in states’ water usage are necessary to avoid dire consequences. . . .

"At 3,370 feet, the reservoir becomes a “dead pool,” meaning water may be unable to flow downstream at all, cutting states off. 'Lake Powell water is about a quarter of the water in the Los Angeles Basin. It supplies water to 90 percent of people in Las Vegas. It supplies water to about half of Phoenix. It supplies water that produces most of your winter vegetables,' Udall said."
