Lake Mead still rising

The water level at Lake Mead at Hoover Dam was 1,043.49 feet (above sea level) as of 7 a.m. Wednesday. That is a rise of 2.78 feet since July 27, the lake’s 2022 low point, of 1,040.71 feet.

The rise of an inch equals about 68,000 acre-feet, according to the Bureau of Reclamation. And one acre-foot is about 326,000 gallons of water. That would mean about 61.6 billion gallons have been added to the lake in the past four weeks.
