Lake Mead may go dry by 2021

Some very bad things could be happening in the US Southwest in the not so distant future.

Lake Mead may go dry by 2021

There is a 50 percent chance that Lake Mead, which was created by the Hoover Dam and the Colorado River, will go dry by 2021 because of escalating human demand and climate change, according to a study by Tim Barnett and David Pierce of the Scripps Institution of Oceanography of the University of California at San Diego.

Lake Mead straddles the Arizona-Nevada border, and Lake Powell is on the Arizona-Utah border. Aqueducts carry water from the system to Las Vegas, Los Angeles, San Diego, and other communities in the Southwest.

The old high water line is at the top of the white band. This was taken two weeks ago.

By 2017, there is a 50 percent chance that the reservoir could drop so low that Hoover Dam could no longer produce hydroelectric power. Water conservation and mitigation technologies and policies thus need to be implemented now, the study stated.

  • Did they now? The aluminum aircraft severed the steel support columns? And how do you know this? Did you have cameras recording that action? Of course not.
  • I have seen many aluminum aircraft versus steel support columns in aircraft hangars for something around 40 years now, and I have NEVER seen aluminum prevail over the steel.
  • Well ya see TC, that energy you mentioned, potential energy you called it, was fulfilled/released ONLY at completion of the event.
