In what cannot be construed as good news for anywhere in the American south-west a new study from the Scripps Institute predicts a 50-50 chance that Lake Mead will run dry by 2021. The lake is the largest man-made reservoir in America and supplies water for somewhere between 20 and 25 million people. Unsurprisingly the federal government, run by a group known for their devotion to scientific findings, is disputing the findings and saying that the federal government would never allow that to happen! Ah yes - the miracle workers that can turn back the tide. Any residents of Alabama, Mississippi, Louisiana or Texas care to weigh in on their success rate?
