Photos: Hoover Dam’s Massive Reservoir Hits Record Low, With No End to Drought in Sight

The reservoir created by Hoover Dam, an engineering marvel that symbolized the American ascendance of the 20th Century, has sunk to its lowest level ever, underscoring the gravity of the extreme drought across the U.S. West.

Lake Mead, formed in the 1930s from the damming of the Colorado River at the Nevada-Arizona border about 30 miles east of Las Vegas, is the largest reservoir in the United States. It is crucial to the water supply of 25 million people including in the cities of Los Angeles, San Diego, Phoenix, Tucson and Las Vegas.

Key Reservoir On Colorado River Expected To Match Record Low

A key reservoir on the Colorado River is expected to dip to its record low Thursday in the latest showing of the drought’s grip on the region.

The surface elevation of Lake Mead along the Nevada-Arizona border is projected to be at 1071.61 feet (326.63 meters) — a measure that was hit in 2016. It’s the lowest level since Lake Mead was filled in the 1930s.
