Drought in the southwestern U.S. will deplete the vast Lake Mead this week to levels not seen since Hoover Dam was completed and the reservoir on the Colorado River was filled in the 1930s, federal water managers said Tuesday.

The projected lake level of about 1,080 feet above sea level will be below the level of about 1,082 feet recorded in November 2010 and the 1,083-foot mark measured in April 1956 during another sustained drought.
