Few Strong Landfalling Atmospheric Rivers Reach California

/in , /by

Few landfalling atmospheric rivers in the current water year have reached California, now in the third year of a statewide drought.

The latest update from the Center for Western Weather and Water Extremes, Scripps Institution of Oceanography at UC San Diego, shows that Water Year 2022 started strong in October, but weaker storms did not ease dry conditions.

Landfalling atmospheric rivers

The CW3E report, Distribution of Landfalling Atmospheric Rivers over the U.S. West Coast During Water Year 2022: Summary Through March, was published April 7.

“While Water Year 2022 began with an exceptional AR over California in October, the state only experienced strong or greater magnitude AR conditions FIVE times, resulting in three straight water years of below normal activity,” according the report.

The report shows that the “lack of impactful events over consecutive years” – water year 2021 and water year 2020, combined with the current water year, has resulted in three straight years of below normal activity. Bottom line: If California hoped strong atmospheric rivers would end the current drought this water year, that’s not happening, at least so far. And the two previous years were a bust, creating extremely dry conditions across the state.

CW3E and Water Authority partnership

The San Diego County Water Authority partnered with the Scripps Institution of Oceanography, Center for Western Weather and Water Extremes, at UC San Diego in 2020 to better predict atmospheric rivers and improve water management before, during, and after those seasonal storms. The Center and its partners share best practices in forecast-informed reservoir operations, increased research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.

“Through our partnership with CW3E and the AR forecasting tools they’ve developed, it better prepares us in management of our water resources using regional storage,” said Jeff Stephenson, Water Resources Manager with the San Diego County Water Authority, in 2021. “This storage, in conjunction with developing multiple water supply sources in the San Diego region, has prepared us for years when rainfall levels are below normal in the region.”

Governor Calls for Increased Conservation in Response to Statewide Drought

/in , /by

March 29, 2022 – “Governor Newsom issued the fifth in a series of executive orders March 28 asking Californians to increase water conservation, while at the same time allowing every local water supplier to determine where additional water-use measures are needed and set rules accordingly. This strong but measured approach for locally appropriate actions will provide aid and assistance to areas of the state that are most suffering the impacts of drought, while maximizing flexibility where warranted by local conditions. The Governor’s approach is especially insightful because it acknowledges and rewards past investment in water conservation and local supply development, as Californians come together to address the real-world impacts of our changing climate.

Pure Water Oceanside Provides New Local Supply of Drinking Water

/in , /by

Pure Water Oceanside is the first operating advanced water purification facility in San Diego County, providing a new local supply. The facility was officially dedicated with a celebration Tuesday in Oceanside. Elected officials and water leaders throughout Southern California commemorated the milestone which coincided with World Water Day.

Pure Water Oceanside purifies recycled water to create a new local source of high-quality drinking water that is clean, safe, drought-proof and environmentally sound.

“On this World Water Day, we celebrate the City of Oceanside’s contribution to managing our invaluable water resources with the opening of Pure Water Oceanside,” said Cari Dale, City of Oceanside water utilities director. “Today we made history by moving one step closer to achieving the goal of greater water independence for not only our city, residents and businesses, but also the region as a whole.”

20% of Oceanside’s drinking water supply

The $70 million project uses advanced technology, including ultrafiltration, reverse osmosis and advanced oxidation to provide 3 million gallons per day or more than 20% of the City of Oceanside’s drinking water supply. The source of the recycled water to create the purified water is from the city’s own San Luis Rey Water Reclamation Facility.

Drought-proof water supply

“Pure Water Oceanside exemplifies our commitment to innovative projects that improve the lives of the citizens who call our great city home,” said City of Oceanside Mayor Esther Sanchez. “Not only will the project safeguard against ongoing drought concerns, but it will also improve the quality and quantity of our local aquifer and reduce our reliance on imported water, ensuring clean and reliable water is available for future generations.”

Pure Water Oceanside addresses a variety of challenges faced by the city. Before the project went online, Oceanside imported most of its water from the Sacramento Bay Delta and the Colorado River, hundreds of miles away. This imported water is subject to rising costs out of the city’s control, requires an enormous amount of energy to transport and is vulnerable to natural disasters and earthquakes. Pure Water Oceanside addresses these challenges by diversifying the city’s water supply and reducing its reliance on imported water.

The launching of Pure Water Oceanside coincides with a larger movement for the region as a whole to create sustainable water supplies in San Diego County. In addition to Pure Water Oceanside, two other water reuse projects are planned for the region: the East County Advanced Water Purification Program and Pure Water San Diego.

(Editor’s note: The City of Oceanside, City of San Diego, Padre Dam Municipal Water District, and the Helix Water District are four of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)

State Water Project Declines Highlight Drought’s Severity

/in , /by

March 18, 2022 – “Today’s announcement about reduced allocations from the State Water Project brings into focus the increasing challenges created by the megadrought. This is an emergency felt throughout the state and we strongly support continued conservation.

“Reduced water deliveries from the State Water Project highlight how the San Diego region’s conservation ethic combined with investments in drought-resilient supplies are paying off. The region uses very little water from the Bay-Delta, and even with reduced allocations, the Water Authority has reliable water supplies for 2022 and beyond.

“During this extended drought, we urge residents and businesses to use water wisely by limiting showers to five minutes, fixing indoor and outdoor water leaks, and ensuring irrigation systems are working efficiently. We must continue to care for our most precious natural resource to sustain our economy and quality of life – not just for today but for our future.”

— Sandra L. Kerl, General Manager, San Diego County Water Authority
