“In a major milestone that prevailing attorneys described as a victory for common sense, the Delta region, the environment, and ratepayers throughout California, the California Supreme Court has denied review of a landmark opinion issued by the Court of Appeal in the Sacramento-based Third Appellate District late last year. That Court’s opinion, first issued on December 31, 2025 and finalized with minor modifications when rehearing was denied the next month, unanimously affirmed a trial court decision holding that the State Department of Water Resources (DWR) exceeded its authority when it approved bond resolutions to finance DWR’s proposed Delta tunnel.  The appellate decision was certified for publication except for a short section involving issues the Court of Appeal did not need to reach after invalidating DWR’s resolutions and revenue pledges. … ”  Continue reading this press release.

Unusually active April weather pattern to continue this week, and possibly beyond, as subtropical northeastern Pacific waters reach record warmth

“What a strange Water Year it has been in 2025-2026! We started the WY with record rainfall during Oct-Dec across much of the central and south coast, including the wettest Oct-Dec period ever observed in Santa Barbara, Ventura, Kern, and parts of LA County. Then, California oscillated between periods of exceptional dryness and quite stormy conditions in Jan-Feb (including one of the largest single Sierra snowstorms in recent decades, the-multi-foot accumulations from which melted almost immediately) before experiencing the by far the hottest and in some cases the driest March on record across much of California and the broader West. Now, in April, the tables have turned once again: quite active and damp conditions have returned, especially in northern and Sierra portions of the state (including notable April mountain snowfall). In fact, it is possible that some locations in the Sierra and western foothills could (with the current forecast) end up seeing a top-3 wettest April on record! … ” Read more from Weather West.

California’s newest solar project isn’t powering homes. It’s powering your water

“At the bottom of the San Joaquin Valley, a low-slung Midcentury building tucked into the green-gold hillside is the beating heart of California’s impressive water delivery system. For more than five decades, the Edmonston Pumping Plant has lifted water nearly 2,000 feet up the towering Tehachapi Mountains, connecting water from Northern California to 27 million people in the southern part of the state.  The plant houses 14 rumbling pumps in two football-field sized wings and is one of the most powerful water lifting systems in the world. But it can need upward of 800 megawatts of electricity to run, making it among the largest single power users in the state.  Now the equation is changing. On a recent weekday morning, dozens of state officials and energy industry representatives gathered at Tejon Ranch, just across the road from Edmonston, to celebrate a sparkling new solar plant that will help power the pumps. … ”  Continue reading from the LA Times. | Read via AOL News.

Do data centers really use so much water? Here are 5 key issues

“As data center projects have popped up across the St. Louis region, driven by the growth of industrial-scale computing for artificial intelligence, one of the primary concerns raised by residents is about water — as in, will data centers consume vast amounts of the local water supply?  Data centers — essentially huge warehouses for servers and computers — need to cool off all of that equipment, which is powered around the clock by electricity.  To keep the equipment from overheating, water-based approaches often represent the most efficient solutions.  The size of the project can determine the water needs. Medium-sized facilities, for example, may use 1 million gallons of water on peak days, while larger ones could need 8 million gallons, experts say. … Here are some key questions about data centers and water usage … ”  Read more from the OC Register.

“DWR‘s April 1 snow survey came in at just 18% of statewide average — the second-lowest on record for that date, trailing only 2015 — and the effects are already hitting the Valley. Tulare Irrigation District reported Kaweah snowpack at 17% and told growers to plan for 4–5 weeks of surface water at 0.4–0.5 AF/acre, down from 6 weeks at 0.65 last summer. Lower Tule River Irrigation District projected 3–5 weeks depending on whether CVP Class 1 holds or drops to 85%, and Exeter Irrigation District is planning around 1.04 AF/acre at $325/acre under an assumed 85% allocation. … ”  Read more from Water Wrights.

UC Merced study explores whether agave could be a future crop for California

“Researchers at University of California, Merced are studying whether agave, -a drought-tolerant plant best known for producing tequila, could become a viable crop in California’s water-strained agricultural landscape.  The research, announced April 16, focuses on how agave performs in the northern San Joaquin Valley, where farmers continue to face ongoing drought conditions and reduced water availability. As crops go, agave is being evaluated for its ability to thrive in hot, dry climates while requiring significantly less water than traditional Valley crops. … ”  Read more from the Los Banos Enterprise.

What’s the oldest lake in the USA? The answer used to be simple – then geologists noticed something that made it complicated

The Great Lakes of the Northeastern US and Canada may be the largest in the continent, and they’re almost certainly the most famous – but compared to some of their smaller cousins, they’re mere babies. Some lakes out there are 10 or more times the age of, say, the 10,000-year-old Lakes Michigan or Huron, defying the odds – and the very laws of geology – to hang on for literally millions of years.  Seriously. The oldest confirmed lake in the world is Lake Baikal, in Russia, and it’s around 30 million years old – meaning it predates, like, daisies and sunflowers. And that might not even be the true record holder: Lake Zaysan, in Kazakhstan, could be more than twice as old as that.  So, we’re just going to say it outright: no lake in North America comes close to either of these Asian ancients. But what is the oldest lake in the US?  Well… it’s complicated. … ”  Read more from IFL Science.

Deregulation might be bearing down on the California Coastal Commission

“To the extent that the state is on a path to quietly weaken the California Coastal Commission — and a growing number of the agency’s critics and supporters say that it is — Jan. 12, 2025, is as good a starting point as any.  That’s the date Gov. Gavin Newsom issued Executive Order N-4-25, the first in a series of orders that said most of the people hoping to rebuild homes or businesses in fire-ravaged Pacific Palisades and Malibu wouldn’t need to get approval from the Coastal Commission.  Newsom, no longer a candidate for public office in California, and perhaps speaking to a national audience, even threw some shade on an agency that’s widely viewed as having kept much of the state’s 840-mile coastline comparatively pristine for the past 50 years.  “As the state helps the Los Angeles area rebuild and recover, we will continue to remove barriers and red tape that stand in the way,” Newsom wrote in his signing statement about his order to sideline the Coastal Commission. … ” Read more from the OC Register.

A deep dive into the Suisun City and California Forever project

“Since 2023, we’ve been following and writing about the audacious plan by the private company California Forever to build a new city of up to 400,000 residents in Solano County, poised midway between the Bay Area and Sacramento. That plan suddenly appeared much more viable in March, 2025, when Suisun City officials reached out to California Forever with a proposal to annex a portion of its vast holdings and incorporate the property into their city. That process is now underway.  Because of the scope and unique nature of the project, we present here a deeper look at the various parties involved, the landscape under consideration and the history and current status of the civic processes required to transform thousands of acres of rangeland into a city. … ”  Continue reading from California Local.

Could Sonic Fire Tech replace traditional water sprinklers in California homes?

“Los Angeles County has issued its first building permit for a 3D-printed concrete home that includes an infrasound-based fire defense system as a voluntary protection component.  Sonic Fire Tech announced that the Sonic Home Defense system is integrated into the interior fire defense plan for a residence in the Eaton Fire rebuild zone.  Monrovia-based PCI Builders received the permit for the project which utilizes 3D-printed concrete (3DCP) technology to produce non-combustible walls.  The construction method produces the walls for a 1,500-square-foot home in approximately 12 hours.  Allison Allain, CEO of PCI Builders, explained her motivation for using new construction methods.  “The day after the fires, I began researching construction technologies that could help ensure this never happens again to my clients,” Allain said. … ”  Read more from Fire and Safety Journal.

Wildfires make soils poisonous

“Soil and rocks throughout the West naturally contain chromium-3, a harmless trace element also found in animals and plants — and even included in dietary supplements. “You could dig a hole outside, wherever you are right now, and you’re going to find some amount of chromium-3,” said Matthew Polizzotto, professor of earth sciences at the University of Oregon.  But researchers are learning that wildfires change the element’s chemical composition, turning it from a nutrient into a poison. Heat from burning soils and plants, combined with oxygen, triggers a process that converts chromium-3 into chromium-6, a carcinogen linked to lung, nasal and sinus cancers. It can also cause asthma, skin irritation and kidney and liver damage.  Chromium-6, or hexavalent chromium, can become airborne in smoke during a blaze or be stirred up in dust after the fire is out, contaminating the air. It can also loiter in a burn scar for years, leaching into groundwater. Firefighters breathing in toxic ash and rural residents who drink contaminated well water are at risk, along with anyone else who encounters chromium-6. … ”  Read more from High Country News.

House Dems condemn Forest Service cuts as Republicans cheer agency’s move West

“U.S. House Republicans from Western states laid out a figurative welcome mat for the U.S. Forest Service Thursday as its chief pitched plans to whittle down the agency’s budget, move its headquarters to Salt Lake City and rely more heavily on states to manage millions of acres.  “I think it’s very interesting what you’re proposing to do, and I support it,” said Idaho Republican Rep. Mike Simpson, chair of the House Appropriations Subcommittee on the Interior, Environment, and Related Agencies.  Democrats on the budget panel grilled Forest Service Chief Tom Schultz about how billions of dollars in cuts to the agency proposed by President Donald Trump could drive up costs for states and stamp out important research.  The subcommittee’s ranking Democrat, Rep. Chellie Pingree of Maine, said she’s deeply worried.  “I guarantee you, my state is not prepared to take over all of the things that the federal government is currently doing.

And lastly … These salmon got high on cocaine. That wasn’t the craziest part.

“In 2022, Jack Brand, an environmental toxicologist, loaded a bunch of Swedish fish with cocaine.  He wasn’t trying to bring a Halloween hoax to life; he wanted to see how salmon in the wild reacted to pollution from the illegal drug.  In recent years, there has been an alarming rise in the number of waterways polluted with cocaine, prompting scientists to wonder how fish might be handling their highs.  As it turns out, fish indeed get wired when on cocaine. In a study published Monday in the journal Current Biology, Dr. Brand and his colleagues show that coked-up salmon swim faster and travel farther than their sober counterparts. This study prompts additional questions about the effects that human drug habits may be having on salmon and other freshwater fish. … ”  Read more from the New York Times.

2026 is shaping up to be a mixed bag in the water world

Mike Gardner, Director on the Western Municipal Water District Board, writes, “As our climate continues to warm and shifts to longer dry periods and shorter, more intense, wet periods with more precipitation in the form of rain and less snow, water providers are concerned about longer term supply if 2026 turns out to be a dry year. On the plus side, California and the Colorado River Basin both had a pretty good year in terms of overall precipitation, but warmer storms with rain rather than snow and a historically warm March destroyed the snowpack that would normally provide capturable runoff throughout the spring. The graphic below shows April snowpack for the last four years. As you can see, we didn’t have any this year. … ”  Read more from the RainCross Gazette.

SYRCL’s 2026 State of the Yuba — Looking back while looking ahead

“On the evening of Wednesday, April 15, approximately 150 people gathered at the Miners Foundry Cultural Center in Nevada City for SYRCL’s annual State of the Yuba — and this year, the celebration carried special weight. Twenty-five years ago, 39 miles of the South Yuba River earned permanent protection under California’s Wild & Scenic Rivers Act. On April 15, the community that made that possible came together to mark the milestone, hear the latest on the health of the watershed, and recommit to the work ahead.  The Miners Foundry provided a fitting setting for the occasion: spacious, historic, and alive with the energy of a community that cares deeply about this river. The evening opened at 5:30 PM with an open house, giving attendees the chance to connect directly with SYRCL staff, explore volunteer and engagement opportunities, and enjoy food from Petra while the Miners Foundry Bar kept the evening warm. There were even activities for kids, and in the spirit of the anniversary, the crowd joined in at the end of the evening to sing happy birthday to the Yuba River and share a slice of cake — a moment of joy that captured exactly why this work matters. … ”  Read more from the South Yuba River Citizens League.

How would the ‘Big One’ impact Sonoma County today? Earthquake hazard modeling provides an idea

“It could strike without warning — even in an age of advanced alerting systems.  A sudden jolt would be followed in some places by violent waves that cause the walls to shudder thunderously and windows to shatter as the ground shakes in all directions for longer than a minute.  Homes in Santa Rosa’s Memorial Hospital neighborhood that aren’t anchored to their foundations will slip off amid the jerking. The contents inside those four walls, from fridges and radiators to bookshelves, will topple over.   Young boys on the baseball diamond at nearby Doyle Park would be hurled to the ground.  Farther north, sections of the vacant former county hospital campus on Chanate Road, abandoned about a decade ago in part over seismic safety concerns, crumple.  A 7.0 or greater magnitude earthquake on the Rodgers Creek Fault that runs beneath central Santa Rosa or a similar-sized shaker on any of the active faults that traverse the region would unleash widespread devastation — something likely not seen in 120 years since the last Big One struck in 1906. … ”  Continue reading at the Santa Rosa Press Democrat.

Critics question feds’ plans for future of Colorado River: In years of severe drought, ‘the system is failing’

“The multitude of water managers tasked with overseeing the drying Colorado River system stand at a dire crossroads.  As a yearslong stalemate in negotiations persists between the seven states that share the river, it’s become increasingly likely that the federal government will impose its own long-term plan, choosing from a range of proposals officials have outlined in recent months.  But experts and water managers across the 250,000-square-mile Colorado River basin are raising the alarm about the five plans, questioning if any of them hold up under the new climate reality. They say the federal plans won’t keep the system from crashing in critically dry years — which are becoming more frequent — and could wreak chaos on the pivotal lifeline for 40 million people in the American Southwest. … ”  Read more from the Greeley Times.

The Colorado River disappeared from the geological record for 5 million years. Scientists now know where it went

“Geologists have solved the mystery of the disappearance from the geological record, millions of years ago, of one of North America’s most important waterways: the Colorado River. A new paper published in Science shows that the river flowed into an upstream lake over the course of a few million years, then likely flowed for the first time into the Grand Canyon. The moment marked the Colorado River’s transition to a continental-scale river as it made its way down to the Gulf of California.  “In some ways, you could really think of it as the birth of the Colorado River that we know today,” said first author and UCLA geologist John He. “There are rivers everywhere, but a river that carries water and sediment across the continent connects life throughout the region, and the entire ecosystem probably changed as a result of the arrival of the Colorado River into the basin.” … ” Read more from UCLA.
