Water levels at Lake Mead hit 1,040.4 feet (317.1 meters) above sea level on Friday, according to federal data. The record follows a winter that produced the worst snowpack on record in the Colorado River Basin. It comes a week after federal officials announced a short-term proposal to stave off a crisis in the beleaguered waterway. Years of overuse combined with drought and rising temperatures have been depleting Lake Mead and Lake Powell, the country’s second-largest reservoir. Together, the two bodies of Colorado River water are the lowest they’ve been in nearly seven decades.
