In my two visits to Las Vegas, I have been somewhat disturbed by the excesses of The Strip, including just how much water is wasted in the Nevada desert.
Maybe the days of such excess are numbered.
From Reuters:
The study by two researchers at the Scripps Institution of Oceanography at the University of California San Diego calculates a 10 percent chance that Lake Mead will run dry in six years and a 50 percent probability it will be gone by 2021 absent other changes.[...]
The uncertainty about when and if the lake will run dry stems from the natural fluctuations of the Colorado River, which feeds the lake, the researcher said. In recent months the flow has been above average, he said, after years below average.
I wonder if Las Vegas will begin to race Los Angeles, to see which metro area can tap Lake Tahoe first.
