California’s giant State Water Project, the network of dams and aqueducts that provides water for 27 million people, will significantly increase deliveries in 2023 after a month of “atmospheric river” storms.
The Department of Water Resources announced Thursday that deliveries will increase from 5% of requested supplies to 30% for the water year than began Dec. 1.
Chula Vista, Calif. – In order to secure additional water supply for our customers, Sweetwater Authority initiated a controlled transfer of water between its two reservoirs on January 26, 2023.
“Late December and January brought substantial rainfall to the region,” said General Manager Carlos Quintero. “However, after four years of dry weather patterns, we are still in need of water. Sweetwater Reservoir is below 40 percent capacity. These transfers are standard operational practices that we conduct to secure the water supply for our customers.”
Water that leaves Loveland Reservoir is transferred through the Sweetwater River channel and captured at Sweetwater Reservoir where it can be treated and distributed to Authority customers at a lower cost than importing water. Recent rainfall and saturated soils have created optimal conditions for the transfer. The Authority anticipates capturing approximately 3,500 acre-feet of water with the transfer. This equates to a savings of approximately $5 million in costs associated with purchasing imported water.
A similar water transfer was last initiated in November 2022. That transfer captured approximately 4,000 acre-feet of water, saving Authority customers more than $6.2 million. Additional runoff will continue to flow in the Sweetwater Reservoir once the transfer is completed from subsequent storms this winter. The Authority expects that after this transfer, there will be sufficient water stored behind Sweetwater Reservoir to provide an adequate supply for over one year. The Authority will monitor the water transfer, which will occur over several weeks, and make modifications as necessary depending on weather conditions.
The Authority worked closely with local landowners and businesses near the Sweetwater River channel, notifying them by mail and phone prior to the start of the transfer to lessen any potential impacts. The Authority conducts controlled transfers periodically and coordinates with the U.S. Fish and Wildlife Service to ensure that environmental needs are met.
January 26, 2023 – The San Diego County Water Authority Board of Directors today welcomed Metropolitan Water District of Southern California Board Chair Adán Ortega, Jr. by hosting a reception for him to meet San Diego County’s community, civic and business leaders.
Ortega took the helm of MWD’s Board on January 10 as the first Latino chair in the district’s 95-year history. In a presentation today during the Water Authority’s formal Board meeting, Ortega focused on shared challenges and opportunities the two water wholesalers face in the era of climate change.
Though recent rains have helped, the city of Carlsbad is still striving to conserve water. The rains have helped, but conservation is still needed, according to the Carlsbad City Manager’s office.
There’s a problem with Tijuana’s lifeline to its single water source – the Colorado River– which forced it make more, costly emergency water purchases from California.
The San Diego County Water Authority recently learned that problems emerged with Tijuana’s aqueduct in December, according to a press release this week. Tijuana requested emergency water from San Diego on Jan. 2, which the Water Authority expedited through a typical months-long approval process involving water agencies that also have to sign-off on emergency orders from Mexico.
Fast action by the San Diego County Water Authority and its partners is helping maintain water service in Tijuana after problems with the city’s aqueduct emerged in December.
Emergency water deliveries started last week after a coordinated effort between the Water Authority, Otay Water District, and Metropolitan Water District of Southern California (MWD). The typical multi-month approval process was compressed into a few days to avoid additional water supply shortages in Tijuana.
“We’re extremely proud of how quickly the Water Authority staff worked to meet the emergency water needs of our neighbors to the south,” said Mel Katz, Water Authority Board Chair. “Coordinating with multiple agencies and getting the necessary approvals in just three days was a team effort and is a credit to the Water Resources and Operations & Maintenance departments.”
Cross-border emergency deliveries started more than 50 years ago and are governed by an agreement between the United States and Mexico to provide Tijuana with a portion of Mexico’s Colorado River supply. The Water Authority provides emergency water deliveries to Mexico through a cross-border connection in Otay Mesa. These deliveries use Water Authority, Otay Water District, and MWD facilities to transport the emergency supplies from the Colorado River to Mexico, which pays transportation costs on deliveries to Tijuana and provides funds for meter connection upkeep. Deliveries are typically planned months in advance due to the number of government agencies involved.
On January 2, the Water Authority received a request for emergency water delivery to Tijuana. Water Authority staff immediately expedited the complex approval process during this unplanned Tijuana aqueduct outage. Those steps included working with the U.S. International Boundary & Water Commission, Otay Water District, and MWD to confirm system capacity availability and establish costs associated with the additional emergency deliveries.
The current water deliveries are scheduled to continue until the end of February. Consistent with the previously approved schedule, planned water deliveries will restart in April and continue through September 2023.
(Editor’s note: The Otay Water District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across San Diego County.)
After the driest three years in the state’s modern history, California suddenly has a different problem on its hands: too much water.
An ongoing series of storms drenching the state has forced officials to take measures unfathomable just a month ago, like releasing excess water from reservoirs and pumping surging river flows into storage.
Good news has surfaced in Los Angeles County’s ongoing battle with water scarcity.
The Los Angeles County Public Works Department announced Monday that more than 33 billion gallons of stormwater have been captured in the early months of the California winter storm season.
It will be used as drinking water and is enough to supply 816,000 people with enough water for an entire year, according to Los Angeles County Public Works Director Mark Pestrella.

Growing up in the shadow of the Rocky Mountains, Andrew Schwartz never missed an opportunity to play in – or study – a Colorado snowstorm. During major blizzards, he would traipse out into the icy wind and heavy drifts of snow pretending to be a scientist researching in Antarctica. Decades later, still armed with an obsession for extreme weather, Schwartz has landed in one of the snowiest places in the West, leading a research lab whose mission is to give California water managers instant information on the depth and quality of snow draping the slopes of the Sierra Nevada — snow that is crucial for the state’s water supply.
