DRIED UP: Lakes Mead and Powell are at the epicenter of the biggest Western drought in history

 

The American West is experiencing its driest period in human history, a megadrought that threatens health, agriculture and entire ways of life. DRIED UP is a series of stories examining the dire effects of the drought on the states most affected — as well as the solutions Americans are embracing.

Nowhere is the Southwest’s worst drought since the year 800 more evident than Lake Powell and Lake Mead, the pair of artificial Colorado River reservoirs whose plunging levels threaten major water and power sources for tens of millions of people.

Already, the region is being forced to adapt to the sweeping effects of climate change, and the lakes and their surrounding area are nearing an environmental point of no return.

The retreating waters have revealed everything from World War II-era boats to multiple sets of human remains, including one in a barrel, a morbid reminder of Las Vegas’s history of organized crime.

Lake Mead is projected to get down to 22 percent of its full capacity by year’s end, while Lake Powell is expected to drop to 27 percent, according to estimations from the federal Bureau of Reclamation. Both now sit at record lows.

...In Lake Mead alone, the net water loss has worked out to more than 6 trillion gallons, according to data from the National Park Service. ..Hoover Dam is already seeing reduced electricity production from Lake Mead’s shrinking size, and the reservoir is projected to fall to approximately 150 feet above “dead pool” status, or the point at which the levels are too low to flow downstream, endangering both power and drinking water...MORE
