Bracing for an ever-growing gap between supply and demand of Colorado River water, three Southwestern states today unveiled an agreement that would cut California’s portion by about 10% in most years.
“Mega-drought” has become a frightful “thing” in public and media discussions. In the past 1,200 years, California had two droughts lasting 120-200 years, “megadroughts” by any standard. Could the state’s water resources continue to supply enough water to drink, grow crops and provide habitat for fish with such an extreme, prolonged drought today?
Clearly, some ecosystems and rural communities would be devastated by such a drought, and it would certainly affect all California residents. But with careful management, California’s economy in many ways could substantially withstand such a severe drought.
Scientists are calling it a “mega-drought” brought on by climate change. The latest U.S. Drought Monitor Map shows large areas of the Southwest are “exceptionally dry,” the worst category. It’s taking a dramatic toll on the Colorado River system that provides water to 40 million people in seven states — and may force the federal government to make a drastic and historic decision. For more than eight decades, the iconic Hoover Dam has relied on water from Nevada’s Lake Mead to cover up its backside. But now, at age 85, it finds itself uncomfortably exposed. Much of the water the dam is supposed to be holding back is gone.
Researchers at Stanford are working on a technology that may be needed more than ever over the next decade, especially if new predictions are accurate. Researchers have recently warned of a potential mega-drought in the western United States – conditions so dry that our drinking water supplies could be facing historic pressures. Experts say keeping the taps flowing could require a patchwork of solutions, including potentially increasing the use of desalination, turning saltwater into drinking water.
