When in the U.S. Bureau of Reclamation announced last month that the country’s largest reservoir, Lake Mead, had fallen to its lowest-ever level at 1,074ft (327m), the question many asked was: How will it affect one of California’s primary drinking sources?
After all, some 19 million Californians, nearly half the state’s population, receive some part of their water from the Colorado River, which flows into the 80-year-old reservoir created by Hoover Dam outside Las Vegas.
By inching below the 1,075ft threshold, the lake’s historic low provoked a Level 1 Water Shortage declaration, signaling the start of potential water cuts to Arizona and Nevada. If Lake Mead sinks to 1,025ft (312m), the Department of Interior will seize control of its management and water allocation, and if it falls to 900ft (274m) it will be considered “deadpool,” meaning that water is no longer passing through the turbines. Falling water levels are the result of a drought in the Colorado River Basin that has dragged on for 16 years and counting.
