ALBUQUERQUE, N.M. (AP) — A key reservoir on the Colorado River has dipped to its record low in the latest showing of the drought's grip on the region.

The surface elevation of Lake Mead along the Nevada-Arizona border dipped to 1,071.56 feet (326.6 meters) at 11 p.m. on Wednesday evening. The level was last hit in July 2016 and is 18.5 feet (5.6 meters) lower than one year ago, according to the U.S. Bureau of Reclamation. It's the lowest level since Lake Mead was filled in the 1930s.
