Chula Vista, Calif. – Sweetwater Authority recently awarded $5,000 to a National City laundromat as part of its Savings Through Efficiency Program (STEP) Grant program. The STEP grant is one of many resources the Authority offers businesses in its service area that help them reduce water use and save money.
The snow water equivalent of California’s snowpack is 190% of average for March 3, 2023. After three years of drought, the bountiful winter is good news, but a drier future demands more conservation and innovative solutions for water supply in the Southwestern U.S.
The Department of Water Resources on March 3, conducted the third snow survey of the season at Phillips Station in the Sierra Nevada. The manual survey recorded 116.5 inches of snow depth and a snow water equivalent of 41.5 inches, which is 177% of average for the location on March 3. Snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.
DWR’s electronic readings from 130 snow sensors placed throughout the state indicate the statewide snowpack’s snow water equivalent is 44.7 inches, or 190% of average for this date.
“Thankfully the recent storms combined with the January atmospheric rivers have contributed to an above-average snowpack that will help fill some of the state’s reservoirs and maximize groundwater recharge efforts. But the benefits vary by region, and the Northern Sierra, home to the state’s largest reservoir Lake Shasta, is lagging behind the rest of the Sierra,” DWR Director Karla Nemeth said. “It will also take more than one good year to begin recovery of the state’s groundwater basins.”
Although the statewide snowpack is currently just behind the record snow year of 1982-83, the snowpack varies considerably by region. The Southern Sierra snowpack is currently 209 percent of its April 1 average and the Central Sierra is at 175 percent of its April 1 average. However, the critical Northern Sierra, where the state’s largest surface water reservoirs are located, is at 136 percent of its April 1 average. With one month of the traditional wet season remaining, DWR is providing updated runoff forecasts to water managers and is closely monitoring spring runoff scenarios and river flows to ensure the most water supply benefits from this year’s snowpack while balancing the need for flood control.
“The recent storms over the past week broke a month-long dry spell in a dramatic way,” said DWR’s Snow Surveys and Water Supply Forecasting Unit Manager Sean de Guzman. “We are hopeful that we will see more cold storms to add to our snowpack for the next month and help set up a long, slow melt period into spring.”
“The results of today’s snow survey is good news for the state’s water supply, especially for those parts of the state that rely on snowmelt as their primary source of water,” said San Diego County Water Authority Water Resources Manager Jeff Stephenson. “The above average snowpack levels come after three consecutive years of drought that resulted in below normal water levels at the state’s major reservoirs. For the San Diego region, the recent local storms allow residents and businesses to turn off sprinklers and irrigation for at least several weeks, if not longer. This allows the region to keep more water in local reservoirs for use later in the year.”

“Despite the recent wet weather and the region’s diverse water supply portfolio, the long-term forecast of a hotter, drier climate, for the Southwest U.S., means that water use efficiency remains a key part of saving our most precious resource, in wet or dry years,” added Stephenson.
Stephenson said that there are rebates and other free services available to residents and businesses of San Diego County that can help conserve water and save money.

To ensure water supply managers have the most current forecasts of snowpack runoff, DWR is utilizing the best available technology to collect the most accurate snow measurements. DWR’s Snow Surveys and Water Supply Forecasting Unit is utilizing Airborne Snow Observatory (ASO) surveys across 12 of California’s major snow-producing watersheds to collect data on the snowpack’s density, depth, reflectiveness, and other factors down to a 3-meter resolution. These flights, which utilize LiDAR and imaging spectrometer technology, provide DWR with more information on water content than ever before, which is then fed into advanced physically based and spatially explicit models to generate the most accurate water supply runoff forecasts possible. These forecasts are used to develop the Bulletin 120 for forecasted spring run-off to determine water allocation and stream flows for the benefit of the environment.

While winter storms have helped the snowpack and reservoirs, groundwater basins are much slower to recover. Many rural areas are still experiencing water supply challenges, especially communities that rely on groundwater supplies which have been depleted due to prolonged drought. It will take more than a single wet year for groundwater levels to substantially improve at a statewide scale. Drought impacts also vary by location and drought recovery will need to be evaluated on a regional scale and will depend on local water supply conditions.
On February 13, Governor Newsom issued an Executive Order directing state agencies to review and provide recommendations on the state’s drought response actions by the end of April, including the possibility of terminating specific emergency provisions that are no longer needed, once there is greater clarity about the hydrologic conditions this year.
Californians should still continue to use water wisely so that we can have a thriving economy, community, and environment. DWR encourages Californians to visit SaveOurWater.com for water saving tips and information as more swings between wet and dry conditions will continue in the future.
DWR conducts five media-oriented snow surveys at Phillips Station each winter near the first of each month, January through April and, if necessary, May. The next survey is tentatively scheduled for April 3.
Chula Vista, Calif. – To assist customers with costs associated with leak repairs, Sweetwater Authority is offering a rebate of up to $75 for repairs made from March 1, 2023 through June 30, 2023. The special rebate is in celebration of the national Fix a Leak Week, which serves as an annual reminder to check household plumbing fixtures and irrigation systems for leaks.
The Helix Water District recently completed an extensive rehabilitation of its Tunnel Hill water storage tanks. The two tanks are above Interstate 8 near the Los Coches freeway exit. The tanks play an important role in the water infrastructure system by storing and providing water to thousands of Helix Water District customers in Lakeside and El Cajon.
The project took two years to complete in several phases. The first phase of the project involved stripping the exterior of the smaller and newer, reinforced concrete tank. The new, natural concrete finish does not require paint and will reduce long-term maintenance costs.

Next, the larger steel tank received new paint and a corrosion-resistant aluminum dome roof. The height of the tank was extended by five feet to improve the tank’s performance and safety in an earthquake, especially to protect nearby neighborhoods. The exterior of the steel tank was recoated.
Both tanks received new interior coatings to prevent corrosion and were replumbed with flexible fittings to prevent breaks and keep the tanks connected during an earthquake.

“The Tunnel Hill Tank improvements are a great example of successful asset management,” said Helix Water District Board President Kathleen Coates Hedberg. “It would have cost over $10 million dollars if we had to replace the tanks. However, rehabilitating cost $3.5 million dollars. Our District is over 100 years old, and it is important to stay on top of our aging water system. We continuously monitor and manage our infrastructure because it’s the best long-term solution for our customers.”
The completed improvements will extend the life of the Tunnel Hill tanks for another 50 to 75 years.
Tanks are the most visible parts of water infrastructure and play a vital role in supplying water for the daily needs of residents and businesses, as well as for emergencies. The Helix Water District operates and maintains 25 tanks across its 50-square-mile service area. Proactive rehabilitations are less expensive than the construction of a new tank.

Eight additional water storage tanks were inspected and repaired in 2022. In addition, as part of its proactive maintenance, crews replaced 11,560 feet of cast-iron pipeline and surveyed 14,728 feet of pipeline route for design.
The district pulled electromagnetic detectors through 12,000 feet of the 36-inch diameter pipeline that delivers water from the Colorado River and Northern California to the R.M. Levy Water Treatment Plant in Lakeside. The detectors measure the pipe wall and identify weak points, facilitating faster, more precise and less expensive repairs. Based on the data, the Helix Water District replaced 805 feet of pipe and installed 34 steel plates and 10 new access manways.

February 22, 2023 – The final shutdown for scheduled maintenance of the San Diego County Water Authority’s First Aqueduct is scheduled to begin February 27. The shutdown will run through March 8, allowing crews to reline portions of the historic aqueduct and perform regular maintenance work that ensures a safe and reliable water supply for the region. Portions of the First Aqueduct were shut down earlier this year for similar work, as part of a proactive approach to saving on future maintenance or replacement costs.
Chula Vista, Calif. – Sweetwater Authority recently acquired a NO-DES system to support the agency’s water main flushing program, which maintains overall water quality. The Authority is the first agency in the region to purchase the water-saving equipment. Bringing the flushing program fully in-house will achieve significant cost-savings for the agency and its customers.
(Editor’s Update: Work started Monday, February 27, as scheduled)
The final shutdown for scheduled maintenance of the San Diego County Water Authority’s First Aqueduct is scheduled to begin February 27. The shutdown will run through March 8, allowing crews to reline portions of the historic aqueduct and perform regular maintenance work that ensures a safe and reliable water supply for the region. Portions of the First Aqueduct were shut down earlier this year for similar work, as part of a proactive approach to saving on future maintenance or replacement costs.
The Water Authority and its member agencies are coordinating to minimize impacts to residents and businesses, while servicing pipelines that are more than 65 years old.
Customers of these affected retail agencies during the final planned shutdown should check with their local water utility if they have questions about localized impacts: Fallbrook Public Utility District, Rainbow Municipal Water District, Rincon del Diablo Municipal Water District, Vallecitos Water District, Valley Center Municipal Water District, Vista Irrigation District, Helix Water District, Yuima Municipal Water District, and the cities of San Diego, Poway and Ramona.
“Taking care of this critical infrastructure during the shutdown season extends the life of the First Aqueduct and helps to avoid both water emergencies and the high costs of emergency work,” said Eva Plajzer, the Water Authority’s director of operations and maintenance. “Maintaining our water delivery system in coordination with our member agencies ensures the continued safe and reliable supply that serves the region’s 3.3 million residents and our $268 billion economy.”
Maintenance work on pipelines is scheduled during low-demand periods to minimize impacts on water service.
The historic First Aqueduct was constructed in the 1940s (Pipeline 1) and in the 1950s (Pipeline 2). On November 28, 1947, the first Colorado River water flowed south from Riverside County for 71 miles into the City of San Diego’s San Vicente Reservoir via the First Aqueduct.
The Water Authority’s Asset Management Program is a key element of providing safe and reliable water supplies to the region. The agency continually assesses and inspects its 310 miles of large-diameter pipelines, which provide treated and untreated water to 24 member agencies in San Diego County. The program is widely recognized for pioneering work, including a patented inspection device.
As assets age, the Water Authority proactively replaces and repairs them to minimize impacts to member agencies and the public. Investments in the latest inspection technologies – including electromagnetic scanning, robotic inspections and 3D tunnel inspections – help the Water Authority’s asset management team detect defects in pipelines and related facilities.

Following the driest three-year period on record, California experienced one of the wettest three weeks in January. But now those extreme wet conditions have activated a water quality standard in the Delta that, coupled with the extended dry period since then, could result in a sharp reduction in the amount of water that can be retained or moved into storage for both the State Water Project and federal Central Valley Project.
The Department of Water Resources and the U.S. Bureau of Reclamation are working in real time to operate the state’s water system to maximize water supply while protecting species and the environment. However, California continues to experience unprecedented swings in weather impacting water management operations.
Because of these extreme weather swings, DWR and Reclamation are taking proactive measures to manage the state’s water supply to store and capture more water in preparation for a return to hot, dry weather in the next two months.
Both agencies submitted a Temporary Urgency Change Petition (TUCP) to the State Water Resources Control Board requesting approval to modify compliance with Delta water quality conditions specified in their water right permits, while proposing measures to avoid impacts on Delta smelt.
DWR and Reclamation typically would seek this kind of change during extremely dry conditions. But the swing to extremely wet conditions after extremely dry conditions has created challenges, and the projects are acting to enable additional opportunities for water storage north and south of the Delta while maintaining protections for species.
The request for the TUCP follows protective actions taken by DWR and Reclamation under state and federal endangered species permits in late December and early January, including the “first flush” action to reduce pumping and allow storm runoff to flow through the system for the benefit of native fish species. Recent monitoring information shows the actions worked as intended, with key fish species moving downstream of the Delta and away from the direct influence of the SWP and CVP pumps.
The water quality and water right permits that dictate SWP and CVP operations require certain water quality conditions to be met at specific compliance points in the Delta to provide for favorable conditions for endangered fish species. In consultation with the Department of Fish and Wildlife, DWR and Reclamation are requesting that the State Water Resources Control Board temporarily move the compliance point in the projects’ water rights permits from Port Chicago six miles east to Chipps Island. The alternative compliance point is anticipated to ensure water quality sufficient to protect beneficial uses.
If approved by the State Water Board, these actions would allow DWR and Reclamation to move and retain more stormwater and runoff in the state’s reservoirs in preparation for continued dry periods. A total of approximately 300,000 acre-feet would be saved for later use by the State Water Project alone.
While the January storms provided much-needed rain and snowfall, they did not end drought conditions for much of the state and California remains in a drought emergency. Regions that rely on the Colorado River system face increasingly severe water shortage conditions, and groundwater basins that serve communities in the Central Valley will not recover quickly from back-to-back years of drought and chronic overdraft.
DWR will continue to work with federal and state partners to be proactive and respond in real time to balance multiple water supply needs.
