Metropolitan Water District, Source of Most of Pasadena’s Water, Considers Declaring Water Supply Alert As Drought Worsens

In response to worsening drought conditions, the board of Southern California’s regional water wholesaler will consider declaring a Water Supply Alert tomorrow that calls upon residents to voluntarily conserve the precious resource.

According to officials with the Metropolitan Water District of Southern California (MWD), Southern California’s water supply has been severely impacted by extreme drought in both the Northern Sierra and the Colorado River, saying crucial storage reservoirs have never been lower.

The Pasadena Water and Power Department (PWP) has purchased imported water from the MWD since 1941. MWD uses aqueducts to transport water from the Colorado River and the Sacramento-San Joaquin River Delta to 26 member agencies, including PWP, in arid Southern California.

As a way to safeguard storage reserves, the board will consider
declaring a Water Supply Alert to stress the urgency of the region’s need to save as much as possible. The action calls for water agencies and consumers in Southern California to voluntarily reduce usage.

On Monday, the U.S. Bureau of Reclamation declared the first-ever mandatory water cutbacks for Arizona, Nevada and Mexico next year due to a shortage from the Colorado River. The federal government’s declaration comes as Nevada’s Lake Mead, the river’s biggest reservoir, measures at its lowest level since the reservoir was created by construction of the Hoover Dam in the 1930s.

MWD General Manager Adel Hagekhalil said Lake Mead’s low levels should be a wake-up call.

“The Colorado River is sending us a clear message: conserve, reuse and recycle,” Hagekhalil said. “The river has been a lifeline for Southern California for more than 80 years. This shortage announcement moves the river into a new era and reinforces the need for Southern Californians to use less water to preserve this critical supply.”

Hagekhalil noted that the next chapter in the history of the river must be “one of collaboration and historic action to stabilize a supply that is so vital to seven states and two countries.”

MWD’s action on Tuesday urging conservation would also support Gov. Gavin Newsom’s call last month for Californians to voluntarily reduce water use by 15% amid worsening conditions across the West Coast.

According to the governor’s office, a 15% cut in water use would save 850,000 acre-feet of water — enough to supply more than 1.7 million households for a year.

Newsom said residents have responded to drought conditions before, and he was confident they would take steps again to ease their water use. He urged residents to limit outdoor watering, use recycled water when possible outdoors, take shorter showers, and only run dishwashers and washing machines when they are full.

Should conditions worsen, MWD officials could later decide to take further action, including imposing financial penalties for excessive use on the agency’s 26 public members and retail suppliers that provide water for 19 million people in six counties.
