The San Diego County Water Authority said a new federal report that forecasts significant increases in reservoir levels along the Colorado River is “welcome news” for San Diego’s water supply.

The report released Thursday by the U.S. Bureau of Reclamation forecasts that a near-record snowpack will raise Lake Mead at Hoover Dam by over 20 feet and Lake Powell farther north by 50 feet.

About two-thirds of San Diego County’s supplies are conserved Colorado River water.

Dan Denham, the Water Authority’s deputy general manager, said the federal report “is definitely welcome news and will buy us time to make crucial decisions.”
