California energy officials on Tuesday said the state’s power planning processes were insufficient to address a crushing heat wave in August that led to rolling blackouts for two days. In a preliminary analysis that was requested by Gov. Gavin Newsom, the heads of three state energy bodies said there was no single cause of the outages.
The San Diego County Water Authority is partnering with the Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and improve water management before, during, and after those seasonal storms.
This month, Scripps’ Center for Western Weather and Water Extremes (CW3E) launched the Water Affiliates Group, which brings together cutting-edge science and hands-on water industry experience to enhance reservoir operations in light of the changing climate. The Water Authority has a long-running alliance with Scripps and is among six founding water agencies statewide.
CW3E and its partners will share and support best practices in forecast-informed reservoir operations, increase research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.
“This partnership with Scripps Institution of Oceanography underscores our commitment to strategic, science-based decision-making and long-term planning,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “By supporting advances in forecasting, we can more efficiently and effectively manage water resources both locally and statewide. This ultimately will benefit everyone in California by helping sustain our economy and quality of life.”

Water Authority General Manager Sandra L. Kerl said the collaboration aligns closely with Governor Newsom’s Water Resilience Portfolio, which prioritizes voluntary agreements, smart water storage strategies and coordination of data collection.
“This is a great example of how water agencies are stronger together by addressing major climate challenges that affect everyone across the arid West,” Kerl said. “By combining forces with some of the leading scientists in the world, we will enhance our planning capacity and be ready to adapt to whatever the future brings.”
Atmospheric river storms cause 40% to 60% of annual precipitation and most of the flood damage on the West Coast. Managing reservoirs for both flood control and drinking water supply retention is challenging because 20th-century practices and regulations are decreasingly relevant due to changing patterns for snowmelt and rainfall.

CW3E is a leader in Forecast Informed Reservoir Operations, which uses data from watershed monitoring and modern weather and water forecasting to help water managers determine the best strategies for retaining or releasing water from reservoirs. CW3E has numerous tools and technologies that affiliates can use to augment water research and improve on-the-ground decisions of water managers. The group’s research covers water supply reliability, flood management, greenhouse gas mitigation, groundwater recharge, public safety, observations, forecasting, decision support, climate outlooks, and hazard assessment.
The Water Authority is working with CW3E to assess how better near-term and long-term precipitation forecasts can improve reservoir planning and operational management in the San Diego region by maximizing local water supplies and the reliability of water resources through a mix of planning processes and real-time decisions.
Joining the Water Authority as founding partners are Sonoma Water, Orange County Water District, Yuba Water Agency, Turlock Irrigation District, and Irvine Ranch Water District.
When Gov. Gavin Newsom downsized the Delta tunnels water project last year, the idea was to save money and try to appease at least some of the project’s critics.
Yet the project remains controversial — and still figures to be costly.
After months of relative quiet, Newsom’s administration released a preliminary cost estimate for the scaled-back project Friday: $15.9 billion for a single tunnel running beneath the estuary just south of Sacramento.
Gov. Gavin Newsom’s new blueprint for California water policy offers a stay-the-course agenda for projects and policies intended to help cope with a warming climate and more volatile weather patterns that already are affecting the state’s irrigation, environmental and drinking water supplies. There are no moonshots and few surprises, and that’s fine; it will be challenging enough to ensure that all Californians are hooked up to safe and reliable water supplies to meet their needs for the coming decade and beyond.
The State Water Contractors, an association of water agencies drawing water from California’s State Water Project, is wading into the newest showdown in the Golden State’s Water Wars.
Tuesday, the association filed a motion to intervene as a defendant in a lawsuit filed by the Natural Resources Defense Council, Defenders of Wildlife, along with a handful of other environmental nonprofits.
The suit, launched in mid-December, is companion litigation to a suit launched by California Gov. Gavin Newsom and Attorney General Xavier Becerra last month.
Water plays a lead role in the state’s political theater, with Democrats and Republicans polarized, farmers often fighting environmentalists and cities pitted against rural communities. Rivers are overallocated through sloppy water accounting. Groundwater has dwindled as farmers overdraw aquifers. Many communities lack safe drinking water. Native Americans want almost-extinct salmon runs revived. There is talk, too, of new water projects, including a massive new tunnel costing billions of dollars.
After a week that saw President Donald Trump visit Bakersfield to pledge more water for Central Valley farmers and Gov. Gavin Newsom’s administration respond with a lawsuit, farmers and water agencies looked for ways to continue work on voluntary agreements intended to ease California’s water disputes.
Trump announced his administration had finalized new federal rules to guide operations in the Sacramento-San Joaquin Delta for the federal Central Valley Project and the State Water Project. The lawsuit filed by the state the next day asserts that new biological opinions prepared by federal agencies lack safeguards for protected species and their habitat.
Gov. Gavin Newsom, in a preemptive strike against President Donald Trump, said Wednesday he plans to sue Trump’s administration to block a controversial plan to increase water deliveries to the San Joaquin Valley.
Newsom’s office said he “will file legal action in the coming days … to protect highly imperiled fish species close to extinction.”
The announcement came just minutes before Trump appeared in Bakersfield to announce he’s finalized an order removing regulatory roadblocks and enabling the giant Sacramento-San Joaquin Delta pumps to deliver additional water to the southern half of the state.
More water will flow toward San Joaquin Valley farmers, President Donald Trump declared at an event in Bakersfield on Wednesday afternoon.
Trump announced the completion of biological opinions that will increase water allocations in Californians.
“A major obstacle to providing more water for the region’s farmers has now been totally eliminated by the government,” Trump said.
During President Trump’s visit to California this week, the commander in chief who campaigned on a pledge of shipping more water to Central Valley farms plans to stop in Bakersfield to boast about a promise kept.
His administration has succeeded in rolling back protections for fish in California, opening the door to more pumping from rivers and streams, and more irrigation deliveries for the state’s vast agricultural economy.
The endeavor is no surprise for a president who has been supportive of industry and hopes to rally rural voters behind his re-election bid. But what confounds some who are worried that Trump’s water plan could undermine the environment is how little the state has done to stop Washington.
