Lake Mead, a key source of water for millions of people in the southwestern United States, could go dry by 2021, a new study finds.
The study concludes that natural forces such as evaporation, changes wrought by global warming and the increasing demand from the booming Southwest population are creating a deficit from this part of the Colorado River system.
Along with Lake Powell, which is on the border between Arizona and Utah, Lake Mead supplies roughly 8 million people in the cities of Las Vegas, Los Angeles, and San Diego, among others, with critical water supplies.
The system is currently only at half capacity thanks to a recent string of dry years, researchers say.
The studys findings indicated that there is a 10 percent chance that Lake Mead could be dry by 2014 and a 50 percent chance that reservoir levels will drop too low to allow hydroelectric power generation by 2017. There is a 50 percent chance the lake will go dry by 2021, the study says.
Researchers say that even if water agencies follow their current drought contingency plans, those measures might not be enough to counter natural forces, especially if the region enters a period of sustained drought or if human-induced climate changes occur as currently predicted.
"We were stunned at the magnitude of the problem and how fast it was coming at us," said study coauthor Tim Barnett of the Scripps Institution of Oceanography of the University of California at San Diego. "Make no mistake, this water problem is not a scientific abstraction, but rather one that will impact each and every one of us that live in the Southwest."
Several studies in recent years have predicted a prolonged period of drought in the Southwest as a result of global warming.
The team's analysis of Federal Bureau of Reclamation records of past water demand and calculations of scheduled water allocations and climate conditions indicate that the system could run dry even if mitigation measures now being proposed are implemented.
"It's likely to mean real changes to how we live and do business in this region," said coauthor David Pierce, a climate scientist at Scripps.
The new study has been accepted for publication in the journal Water Resources Research.
Eventually at least.
Crapola at best.
Please allow me to contribute to the effort.

This could have been predicted earlier, what with Bees and Colony Collapse Disorder. When bees disappear, lakes consisting of honey wine disappear too.
We are doomed, doomed, DOOMED!
This is what happens when you build huge cities in a desert without their own water supplies. And then to suggest that it’s because of global warming.... absurd.
...or maybe it won’t.
Dodo: If you weren’t smart enough to plan ahead, then doom on you.
Other Dodos: [chanting] Doom on you. Doom on you. Doom on you. Doom on. ...
Amen.
Building cities in deserts have more to do with drying up water supplies than any global warming scam.
Actually, we should not dismiss this as just another Global Warming scare. Instead, think of it as an article on water shortage in the Southwest that just happens to mention Global Warming in order to lend credence to itself.
The watershed for Arizona has been suffering from a real drought for several years. We really need more water to support the growing populations in the Southwest and instead, the available water is declining. There’s not much water in the Colorado River by the time it gets to Yuma Arizona.
I notice they are (immediately!) dragging in global warming - of course, without any other justification or rational.
See, 1/2 of one degree change in 38 years just HAS to mean doom (and taxes) ....
And in other "What If" News:
If the oceans boil we're screwed.
If the moon crashes to earth you might not have time to get away.
If the sun goes super nova things will heat up.
So the sea level is going to rise 27 feet and the lakes are going to dry up? Sounds like we better start digging canals pronto! ;-)
