Opinion: Investment in Delta Tunnel, Sites Reservoir Will Ensure Water Supply

/in , , /by /CalMattersby Heather Dyer

California just recorded its’ third driest winter in history, so it’s no surprise that State Water Project deliveries have been cut to just 5% of contracted amounts.

This is bad news for regional water agencies who collectively depend on the State Water Project for a fourth of their water supply.

But these agencies have seen the climate change writing on the wall for a long time. In fact, Southern California has been in an extended drought for the last 20 years. Because of this, 11 San Bernardino Valley water agencies have identified close to $650 million worth of local stormwater capture, storage and recycling projects they plan to build over the next 50 years to lessen their dependence on State Water Project imports.

San Diego County Mitigation Efforts Aid in California Drought Battle

/in , , /by /10 News (KGTV) San Diegoby Zac Self Quoted: San Diego County Water Authority

As the drought deepens throughout California, San Diego County has postured itself to make it through dry spell conditions as a result of planning and mitigation efforts.

After experiencing a severe drought in the early 1990s, San Diego County officials went to work on diversifying its water supply. At the time, the region was hit with 50% supply reductions because it relied almost entirely on a single source. Since then, however, the San Diego County Water Authority has taken a varied approach. According to the authority, the region has added a new transfer of conserved agriculture water from Imperial Valley and completed the All-American and Coachella Canal lining projects to receive conserved water from the Colorado River.

“The Water Authority’s draft 2020 Urban Water Management Plan shows that regional investments in a ‘water portfolio approach’ to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have sufficient water supplies through the 2045 planning horizon – so the region’s residents and economy remain safe even during multiple dry years,” the authority told 10News.

Water Usage Down Sharply in San Diego, Shrinking City’s Reliance on Expensive Imported Supplies

/in , , /by /The San Diego Union-Tribuneby David Garrick Mentioned: San Diego County Water Authority

San Diego’s vulnerability to water shortages and drought is shrinking significantly because residents and businesses are using less water and city officials are boosting the local supply.

A new city analysis shows local water use dropped sharply from 81.5 billion gallons in 2007 to about 57 billion gallons in 2020, even though the city’s population has grown about 1 percent per year over that time.

Investments Protect San Diego Region from Drought

/in , /by

It has been a very busy few weeks in the water world, with the governor declaring a drought emergency in two Northern California counties and increased discussions across the West about how to manage water through a very dry year.

While the challenges are real in some parts of the state, I applaud Governor Newsom for taking a targeted, flexible, and iterative approach to drought management. This approach provides support for individual regions that are suffering from drought while also recognizing regions like San Diego County that have sufficient water supplies due to three decades of investments in supply reliability.

Water Portfolio Strategy

The governor’s Water Portfolio Strategy aligns with our region’s long-term investments in a diversified water portfolio, desalinated seawater, conserved water from Imperial County, local water-use efficiency measures, member agency recycled water and local supply projects, and increased water storage. It’s especially important to highlight the efforts of our ratepayers, who have cut per capita water use by nearly half since 1990. Because of those actions and others, our residents have enough water for 2021 and future dry years.

In addition, the innovative and resilient water supply portfolio created by the Water Authority and its 24 member agencies puts our region in a unique position to provide solutions that can help California weather this drought and future droughts – for instance, by storing water in Lake Mead. We look forward to working with the governor and his staff to collaborate on projects and programs where we can use our assets and experience to help areas that are hit hard by drought in the face of a changing climate.

Finally, I invite you to read my latest commentary in The San Diego Union-Tribune that addresses many of the issues being faced statewide and how that impacts San Diego County.

I hope you also take a moment to appreciate the cartoon in the U-T by Steve Breen, which perfectly captures our investments over the past three decades.

Opinion: Drought-Tolerant San Diego Won’t Go Thirsty in the Dry Stretch Ahead

/in , , /by /The San Diego Union-Tribuneby Michael Smolens Quoted: San Diego County Water Authorty

San Diego takes droughts very seriously. That’s why the region is well-positioned to weather an extended dry spell with enough water.

Local officials don’t shrug at the drought conditions across the state that have triggered emergencies in a couple of northern counties. For one thing, the wildfire threat can be as dangerous here as anywhere.

San Diego may be more drought-tolerant than in the past when it comes to water, but it may never be fire-resistant.

Opinion: How San Diego County’s Water Supply Investments Protect Our Economy and Quality of Life From Drought

/in , , /by /The San Diego Union-Tribuneby Gary Croucher Quoted: San Diego County Water Authority

Increasingly ominous signs suggest that we are entering another multiyear drought in California. The State Water Project recently reduced projected water deliveries for 2021 from 10% of requested supplies to 5 percent, and on April 21, Gov. Gavin Newsom declared a regional drought emergency in the Russian River watershed in Northern California.

But it’s a different story in San Diego County.

Water Authority Offers Help to Regions in Need During Drought

/in , /by

The San Diego County Water Authority’s Board of Directors April 22 authorized staff to explore opportunities to help other water districts weather an emerging drought across California.

Three decades of investments in supply reliability, along with a continued emphasis on water-use efficiency, mean the San Diego region has sufficient water supplies for multiple dry years. Those investments include high-priority conserved water from the Imperial Valley, seawater desalination, and access to the Semitropic Original Water Bank in Kern County, where the Water Authority has stored about 16,000 acre-feet of water.

The Board authorization allows Water Authority staff to assess selling, leasing, or swapping its Semitropic water with agencies that need it. Increasingly severe impacts of drought are already being felt  in Central and Northern California. Any agreement recommended by staff would be brought to the Board for approval.

Innovative ideas to improve water management

“Given the extraordinarily low 5% allocation on the State Water Project and the location of our groundwater in the Central Valley, it’s a perfect time to explore mutually beneficial agreements with agencies that need more water this year,” said Water Authority Board Chair Gary Croucher. “The Water Authority is committed to innovative ideas like this to improve water management across the arid West and at the same time benefit San Diego County ratepayers.”

This water supply and opportunity is available because in 2008 the Water Authority secured extra water for the San Diego region in preparation for future droughts. At the time, the Water Authority worked with the Metropolitan Water District of Southern California to swap that water for 16,000 acre-feet of MWD water stored in the Kern County water bank. Due to other water supply investments which have come on-line, the Water Authority has not needed to call on its Semitropic water.

Help for agencies during drought

Given its current water supply portfolio, Water Authority staff will look at the potential to use its stored water to help other agencies and generate revenues for the benefit of San Diego County ratepayers.

At the same time, the Water Authority continues to pursue authorization to store water supplies which are qualified for storage in Lake Mead, which is declining due to a two-decade drought in the Colorado River Basin. If the Water Authority could store water there, it would also open up the potential for other water management strategies to improve Lake Mead water levels and water supply reliability for the Basin States.

“It’s in everyone’s best interest to think creatively about long-term water management even though that will mean doing new things in new ways,” said Croucher. “A fresh, collaborative approach is our best hope to act as a multi-state region to meet the needs of people, farms and the environment.”

California is facing a second consecutive dry water year. Snowpack and precipitation are below average in both the Northern Sierra and the Upper Colorado River Basin, and most California reservoirs are below their historical averages for this time of year. On March 23, the California Department of Water Resources reduced the State Water Project allocation from 10% to 5%. The only other year on record with such a low SWP allocation is 2014. Following the state’s April 1 snow survey, DWR Director Karla Nemeth declared the state’s conditions “critically dry.”

Water supply diversification strategy

Those circumstances highlight the importance of San Diego County’s supply diversification strategy that began after the drought of the early 1990s. Back then, the region was hit with 50% supply reductions because it relied almost entirely on one source. Since then, the region has added a significant new transfer of conserved agriculture water from the Imperial Valley, completed the All-American and Coachella Canal lining projects to receive conserved Colorado River water, invested in the Claude “Bud” Lewis Carlsbad Desalination Plant, and continued to embrace water-use-efficiency measures that have become a way of life in San Diego County.

The Water Authority’s draft 2020 Urban Water Management Plan shows that regional investments in a “water portfolio approach” to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have sufficient water supplies through the 2045 planning horizon – so the region’s residents and economy remain safe even during multiple dry years.
