esquire.com – Here, courtesy of Time, is a nice photo from space of the current state of Lake Mead as compared to what used to be Lake Mead. As it happens, there is less of Lake Mead than there ever has been before, which is a problem because Lake Mead is the largest reservoir in the United States. Created by the construction of Hoover Dam, a big government project of the past, Lake Mead provides drinking water to four states, including California. In California, it supplies water to Los Angeles, a fairly good-sized port city on the Pacific coast. There is now only 37 percent of Lake Mead left. We are entering the age of Thirsty Math.
