San Diego’s Water Portfolio Approach ‘Model for California’

State officials Thursday toured San Diego County water infrastructure to get a first-hand look at the region’s successful water portfolio approach for supply diversification.

California Natural Resources Agency Secretary Wade Crowfoot, Deputy Natural Resources Secretary Thomas Gibson, State Department of Food and Agriculture Secretary Karen Ross, and State Water Resources Board Chair E. Joaquin Esquivel were here to assess the region’s water projects as part of their new role in developing a water portfolio strategy for the state.

Portfolio approach benefits region

“The region is proof that the portfolio approach works,” said Water Authority Board Chair Jim Madaffer. “The Water Authority and its 24 member agencies continue to develop local projects and explore opportunities that would benefit the region, the state, Mexico and the Southwest.”

At a luncheon meeting and panel discussion at University of California, San Diego following the tour, the agency officials joined a group of more than 150 people to hear how the portfolio approach can help California and the Southwest meet water supply challenges.

Along with the Water Authority Board of Directors, elected officials, business, community and state and local leaders gathered in an auditorium at the Southwest Fisheries Science Center on the La Jolla campus.

Jim Madaffer and Water Portfolio approach

“The state needs to look at a global approach to managing water,” said Water Authority Board Chair Jim Madaffer.

Madaffer said during the meeting that San Diego’s portfolio approach has been successful in increasing the region’s water supply reliability through diversification and innovation.

“The Water Authority’s model is one that can be replicated across the state to help ensure a secure water future for all Californians,” said Madaffer.

State agency leaders echoed Madaffer’s comments.

“San Diego has been a leader in the water portfolio approach,” said Wade Crowfoot. “We have to make the investments to build regional water resilience as part of the Governor’s order to develop a portfolio to manage water in California.”

Water resilience portfolio for 21st century 

The Water Authority invited the officials to visit after Gov. Gavin Newsom issued an Executive Order in April, directing state agencies to “prepare a water resilience portfolio that meets the needs of California’s communities and environment through the 21st century.”

In his May letter to Newsom, Madaffer thanked the governor for the “wisdom and leadership” with the issuance of Executive Order N-10-19, and invited the governor to tour San Diego County’s cutting-edge water facilities.

Newsom’s order also directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.”

The California Natural Resources Agency, the California EPA, and the California Department of Food and Agriculture, in consultation with the Department of Finance, were directed by Gov. Newsom to, among other tasks, “identify key priorities for the administration’s water portfolio moving forward.”

“Governor Newsom wants us to think long and broadly on water,” said Crowfoot. “He wants us to get away from the silos and conflicts on water in California – the mindset of environment groups versus farmers, north versus south, urban versus rural – and work together on water resiliency.”

Significant investments in regional water strategy

“The Water Authority and its 24 member agencies have made significant investments in the last two decades to diversify our water supply, creating a portfolio of resources to support our region’s 3.3 million people and $231 billion economy,” said Madaffer.

During the tour, the officials got a first-hand look at some of those investments, including the San Vicente Reservoir, Olivenhain Reservoir, and the Claude “Bud” Lewis Carlsbad Desalination Plant.

Global Warming creates water supply challenges

Scripps Institution of Oceanography research meteorologist Dan Cayan told the audience that temperatures and dry spells will increase in California in the future, making water storage, conservation, and forecasts even more critical.

“Global warming climate models show the Sierra Nevada snow pack will be 50% less in 2090 than today’s average April 1 snowpack,” said Cayan.

Cayan said observations and climate model projections indicate climate change is occurring and will grow stronger. California should expect 1.5-2 degrees Fahrenheit warming by 2050, he said.

New regional pipeline study

Water Authority Assistant General Manager Dan Denham described a new study that will explore the viability of a regional pipeline to transfer water from the Colorado River to benefit multiple users in San Diego County and across the Southwest.

The pipeline system is one of a handful of ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.

Map indicates three potential routes for a proposed regional pipeline system that would move Quantification Settlement Agreement water directly from the Imperial Valley to San Diego. Two of the routes (the light blue and purple lines) follow a southern route. The third proposed route, (shown in both a yellow and darker blue line) follows a northern path. Graphic: Water Authority

Creating a pipeline to transfer Colorado River water to the San Diego region has been studied periodically over decades.

But the new study is focused on how a regional pipeline could provide multiple benefits as part of a long-term water management strategy for California and the Southwest.

The expanded review will consider a system that could create much-needed storage opportunities for the Imperial Irrigation District that could support agriculture while addressing critical issues like the Salton Sea and the need for more renewable energy development.

When Will California Become Too Hot To Grow Wine Grapes?

We know that climate change is going to alter wine. In fact, we know that it already has. But we are still working toward a deeper understanding of what it will look like — and what can be done about it. The latest step toward that understanding is a study published Tuesday by the Union of Concerned Scientists, one of the most detailed forecasts to date of extreme heat across the U.S. As The Chronicle’s environmental correspondent Kurtis Alexander reported, the study warns that most of the country will see more than double the number of days with a 100 degree heat index by 2050, unless something drastic is done.

After 800,000-Gallon Spill, Chevron Site Is Still Leaking Oil

On the same day Sen. Dianne Feinstein chastised Chevron Corp. for keeping an 800,000-gallon spill outside Bakersfield “under wraps,” California officials confirmed Thursday that the site was once again seeping a hazardous mix of oil and water. The new leakage occurred in a surface expression vent in the Cymric oil field, near the Kern County town of McKittrick, according to the state Division of Oil, Gas and Geothermal Resources. The vent is one of the locations where three previous leaks released about 800,000 gallons of oil and water.

OPINION: Coalition Of Agencies, Environmentalists Sees Future For Aging Dam

While California contemplates new dams for its thirsty future, it’s also thinking about taking out old ones. Along with advancing plans to demolish three dams atop the Klamath River, there’s a movement to rethink and possibly take out a water and power dam in the Mendocino County back country. Pacific Gas and Electric Co. is walking away from the Potter Valley project and Scott Dam, built east of Ukiah in 1922. A new federal license will be costly and the utility has plenty to do working its way out of wildfire-caused bankruptcy. What’s coming next is intriguing: A coalition of local agencies and a dedicated fishing group, California Trout, are talking up a takeover of the dam.

Zone 7 Has Backup Plan To Keep Water Moving In Power Outages

If PG&E shuts down power as part of its plan to prevent fires in northern California, the water will keep flowing in the Valley, thanks to Zone 7 Water Agency’s preparations. PG&E sent out notices with May bills that stated it had formed a Public Safety Power Shutoff program that would halt power deliveries in rural areas that may be threatened by wildfires. Investigators found that last year’s fatal Camp Fire, in Butte County, was caused by sparks from PG&E equipment.

OPINION: The Changing Delta’s Challenges

The Sacramento-San Joaquin Delta is essential for the Central Valley’s economy, well-being and ecosystems. It is a major supplier of land for local agriculture, water for Central Valley farms and Bay Area and southern California cities, recreation for Californians and habitat for native species.

The Delta is ever-changing, from its origins 6,000 years ago as rising post-Ice Age sea levels drowned the confluence of local rivers to form a massive freshwater marsh. Since the 1800s this marsh was diked and drained for agriculture, leading to continuing land subsidence, as much as 25 feet below sea level in some places. Major federal and state water projects altered and reversed its water flows.

CAISO To Require Equipment Improvements For Inverter-Based Generation

The California Independent System Operator (CAISO) will require equipment improvements for renewable energy resources, requiring inverter-based generators to inject reactive current during low-voltage conditions in order to maintain grid reliability.

The Federal Energy Regulatory Commission (FERC) approved the ISO’s tariff revisions in a July 2 order. The change is designed to allow increased integration of wind and solar power.

Dozens of Environmental Groups Want To Contribute To Newsom’s Water Portfolio Plan

A coalition of 55 environmental, fishing, and water policy groups has written Gov. Gavin Newsom, backing his Water Portfolio planning process, and announcing that they plan to take an active part with their own proposals for the plan.

Newsom announced his Water Portfolio on April 29. He ordered three state agencies — Natural Resources, EPA, and Food & Agriculture — to prepare “a water-resilience portfolio that meets the needs of California’s communities through the 21st Century.”

 

California Department Of Water Resources Approves Nine Alternatives To Groundwater Sustainability Plans

The California Department of Water Resources (DWR) today announced approval of nine alternatives to groundwater sustainability plans (GSPs) submitted by water agencies to meet requirements of the Sustainable Groundwater Management Act (SGMA).

SGMA requires local agencies throughout the state to sustainably manage groundwater basins. Basins ranked as medium- or high-priority are required to develop GSPs or submit an alternative.

An alternative may be an existing groundwater management plan that demonstrates a reasonable expectation of achieving sustainability within 20 years. It may also be a basin adjudication with existing governance and oversight, or a 10-year analysis of basin conditions showing sustainable operations with no undesirable results such as subsidence, saltwater intrusion, or degraded water quality.
