Hydrologists report that 63 trillion gallons of ground water have been lost in the West due to drought. Lake Mead is at its lowest level since the Hoover Dam was constructed in the 1930s. NBC News reports that big water consumers, like California, may find its water rationed if weather conditions remain the same or worsen. The lake is the largest reservoir in America, and visitors to it can identify distinctive “bathtub rings” that validate the significant drop in water levels. Above average moisture upstream, in Colorado, will cause Lake Mead to rise in the fall. Similar to Lake Veret and False River, Lake Mead is a playground for boating enthusiasts.
