Strongest El Niño in a century? What this rare phenomenon could bring.

“The chances for a planet-warming super El Niño this year are rising, according to an updated model forecast issued Sunday.  The latest ECMWF outlook indicates there’s a high chance for a supercharged version of the climate pattern that affects regional-to-global weather patterns this summer or fall, doubling down on a super El Niño prediction from last month.  During a typical El Niño, a warming patch of water in the equatorial Pacific Ocean influences what regions experience droughts, floods, extreme heat, hurricanes and declining sea ice. During relatively rare super El Niño events, happening once every 10 to 15 years on average, the effects may be stronger, more persistent and more widespread.  That’s because sea temperatures in that key region of the Pacific Ocean warm more than 2 degrees Celsius (3.6 degrees Fahrenheit) above average, leading to a strong atmospheric response — typically peaking in December or January. … ”  Read more from the Washington Post.

A biblical megaflood could hit California at any moment. And that’s only the beginning

“California. The Golden State. Home to almost 40 million people and the world’s fourth-largest economy, it is a global capital of technological innovation and the epicentre of the entertainment industry. But beneath the glitz and glamour, prosperity and prestige, the state is a natural disaster hotspot.  From earthquakes to wildfires, Californians are accustomed to battling the forces of nature. … California is built on extremes at both ends. Alongside vast wealth sits deep poverty; alongside years of drought and fire come episodes of torrential rain and devastating floods.  Only in 2023, hundreds of thousands were left without power as storms and flooding battered the state. Highways collapsed, trains derailed, and thousands were evacuated from their homes.  That sounds bad enough, but according to the latest research, episodes like this pale in comparison to what’s to come.  Scientists and officials are now preparing for not one threatening storm, but a 30-day maelstrom of megastorms unlike anything seen in the state for almost 200 years. … ”  Read more from BBC’s Science Focus.

Late-week storm to bring some rain, mountain snow to California before spreading into Southwest

“A storm from the Pacific is forecast to spin slowly toward California later this week before drifting inland over the weekend, bringing some much-needed rain and a bit of high-elevation snow. While the storm is far from the strongest of the rainy season, its extended duration will bring multiple days of showers for some locations.  Dry weather will persist across much of the West through midweek, along with a renewed warming trend in parts of the interior Southwest. Meanwhile, a departing storm will bring showers and thunderstorms to New Mexico and Colorado into Tuesday night. … The first showers from the Pacific storm will arrive along the northern California coast Wednesday night and reach the San Francisco area on Thursday. … ”  Read more from AccuWeather.

The weather system off California’s coast is making a beautiful circle in the sky

“The weather pattern that will hit California this week looks spectacular on satellite.  Imagery from the NOAA GOES-West satellite, orbiting 22,236 miles above the surface, shows a large spiral of clouds spinning off the California coast.  That spiral is a cut-off low. A cut-off low forms when a dip in the jet stream deepens so dramatically that it pinches off entirely, leaving a pocket of cold air spinning in isolation with no steering flow to push it along. The system slows, wobbles, and can linger for days, making it one of the harder setups for forecasters to pin down. … This particular cut-off low will take its time moving toward California and won’t get close to the coast until sometime on Thursday. … ”  Read more from the San Francisco Chronicle.

Surprising effects of fire on fish and freshwater ecosystems

“Fire is a fact of life for many ecosystems. While many species are adapted to these recurrent natural phenomena, fires continue to increase in frequency, intensity, and severity. Along with more frequent fires also comes salvage practices such as timber harvesting and replanting. While fires and post-fire salvage practices touch the whole ecosystem, most post-fire studies focus on economically and culturally important species like salmonids, without looking at effects across the entire freshwater community. In a time when fire frequency and severity are on the rise, this information could prove critical to inform post-fire management practices. … ”  Read more from FishBio.

Managed wetlands prove a culinary hot spot for San Francisco Bay fish

“California’s Bay Area may be a culinary hot spot for people, but food options for fish in the San Francisco Estuary have been limited and declining in recent decades.  A study from the University of California, Davis, shows there is a part of the estuary that is teeming with fish food—the managed wetlands of Suisun Marsh.  The study, published in the journal Estuaries and Coasts, found that managed wetlands produce 11 to 22 times more zooplankton than tidal habitats, including tidal restoration sites.  Zooplankton are drifting, microscopic animals that form the foundation of a fish’s diet. The paper said zooplankton increases in response to controlled floods.  If managers adopted strategies to connect managed wetlands with tidal habitats, they could time seasonal flood releases to send a DoorDash-like delivery of plankton pulsing into waterbodies to feed more fish. … ”  Read more from ECO Magazine.

Video shows impressive behind-the-scenes footage of California dam removal project

“The “trust the process” philosophy doesn’t just refer to patient Philadelphia 76ers fans.  When it comes to removing a dam and restoring rivers, the optics and the final vision take some time to materialize. A video shared by the nonprofit California Trout on Facebook and Instagram showed the arduous process in motion.   The footage was of Pacific Gas and Electric Company’s removal of the Inskip Diversion Dam from the South Fork of Battle Creek in Northern California. This project aims to support local fish species, including trout, Chinook salmon, and steelhead, by restoring their natural habitats.  “The dam no longer served a useful purpose and the benefits of removing the dam outweigh the benefits of leaving it in place,” California Trout wrote in the caption. “Like surgery, river restoration is not necessarily pretty…at first.” … ”  Read more from The Cool Down.

California agriculture at a crossroads: Insights from Ryan Jacobsen at Fresno State

“At a recent gubernatorial debate hosted at Fresno State, agricultural leadership took center stage as Ryan Jacobsen, CEO of the Fresno County Farm Bureau, shared his candid perspective on the future of farming in California. Speaking with AgNet West’s “Ag Meter”, Nick Papagni, Jacobsen offered a grounded, insightful look into policy, regulation, and the pressing challenges facing farmers today.  Jacobsen entered the debate expecting broad political generalities—but walked away impressed.Rather than vague talking points, candidates delivered specific proposals and demonstrated a clear understanding of the issues. While ideological divides were evident, Jacobsen noted an unexpected level of agreement on certain agricultural concerns. The forum ultimately helped elevate rural and farming issues that are often overlooked in statewide political conversations. … ”  Read more from Ag Net West.

For her, the significance went beyond politics.  She emphasized how meaningful it was to see 30 agricultural groups unite, highlighting the Central Valley’s importance and reinforcing agriculture’s critical role in California’s economy. … ”  Read more from Ag Net West.

Bill calls for “surfing reserves” off California’s coast to protect threats

“California’s coastline is dotted with world-class surf breaks — from the iconic Malibu that helped fuel the culture and popularity of the sport to the monster waves at Mavericks in Northern California that test elite big wave surfers to Lower Trestles, the site of the LA28 Olympics — and proposed legislation could protect them.  A bill authored by Assemblymember Jacqui Irwin, D-Thousand Oaks, would designate state surfing reserves using the California Coastal Act of 1976, which aims at giving protections for coastal areas from development and ensuring public access.  Irwin notes that the coastline spans 1,100 miles, and the state is home to a number of world-famous surf breaks.  “These breaks are destinations for millions of domestic and international surfers, and generate several billion dollars of economic activity every year,” she said in a statement. “While the state is a leader in ocean conservation, California does not have a policy framework designed to specifically protect surf resources, which are all the natural resources and conditions that work together to create surfable waves.” … ”  Read more from the OC Register.

This California lake revolutionized American environmental law

Caroline Tracey, author of “Salt Lakes: An Unnatural History, writes, “Mono Lake stands out in the high desert of eastern California, a disc of blue amid a landscape of sagebrush and sandy soil. In 1872, Mark Twain called it “this lonely tenant of the loneliest spot on earth.”  Lonely as it may be, legal cases involving Mono have revolutionized environmental law in California, the American West and the U.S., bringing about important changes to water use and air quality regulations in recent decades and showing the way ahead for tribal resource rights today.  In the early 20th century, the Los Angeles Department of Water and Power built the Los Angeles Aqueduct to capture snowmelt from the eastern face of the Sierra Nevada and channel water to the city. Within a decade, California’s Owens Lake, where the water had naturally flowed and collected for thousands of years, dried up. In 1941, the Los Angeles utility added an extension that allowed it to drain water from the nearby Mono Basin, tapping rivers and streams that had long fed Mono Lake. … ”  Read more from the San Francisco Chronicle.

Humboldt Bay water districts update invasive mussel prevention plan for Ruth Lake

“Boaters heading to Ruth Lake this summer will face a new mandatory 30-day quarantine requirement aimed at keeping highly destructive invasive mussels out of the reservoir that supplies water to the Humboldt Bay region.  The Humboldt Bay Municipal Water District and the Ruth Lake Community Services District announced the joint implementation of the quarantine program for watercraft entering Ruth Lake with ballast tanks or other components that cannot be drained. The districts said the measure is intended to prevent the introduction of golden, zebra, and quagga mussels, which can clog water infrastructure, damage boat engines, and destroy native ecosystems. … ”  Read more from KRCR.

Wintry spring to arrive in Tahoe: prolonged rain and mountain snow expected

“Following months of limited storm activity, the Tahoe region could see a more sustained period of precipitation as a new weather pattern moves in later this week.  “After a frustrating winter with only two stormy weather pattern periods from the end of November through March, we look to finally have a pattern coming that we could have used a lot more this season,” wrote forecaster Bryan Allegretto on OpenSnow.  Allegretto said a broad area of lower pressure may settle over the West Coast by April 9 and linger through at least April 20. Unlike midwinter systems driven by a strong jet stream and colder air masses, this pattern will feature weaker, slow-moving low-pressure systems.  “These are weak cut-off or closed lows that are moving through slowly and will get a boost in showers from daytime heating,” Allegretto wrote. “Overall, above-average precipitation for this time of year is forecast.” … ”  Read more from the Tahoe Daily Tribune.

Balancing growth and conservation in Nevada’s water future

“On a peaceful Saturday evening last summer in southwest Reno, resident and homeowner Brian Burriss kneels beside a patch of desert sagebrush and river rock, carefully twisting a drip emitter, as the sun sets behind the mountains, painting the sky with a warm orange glow. Water trickles out slowly, each drop disappearing instantly into the dirt, parched from summer heat.  The sound of sprinklers once filled these summer nights, a soft, rhythmic hiss of water on grass. Now, the street is mostly silent. A few years ago, this neighborhood was a lush carpet of green, with grass lawns marking the streets. Today, much of those are gone, replaced by drought-tolerant shrubs and pale gravel that gleams in the heat.  For Burriss, this landscaping choice is not just aesthetics. It’s economics.  “You pay for every gallon,” Burriss said, straightening up. “So you start thinking about what really needs watering.” … ”  Read more from the Sierra Nevada Ally.

Bolinas water system leak releases 300,000 gallons

“A leak in a water line released about 300,000 gallons and prompted a service shutoff, according to the Bolinas Community Public Utility District.  Corrosion caused a 1-inch hole in a 10-inch line that carries water from storage tanks to the distribution system, said Georgia Woods, the general manager. The district discovered the leak Saturday and turned off water to customers for about three hours, Woods said.  “An additional three hours were required to fully recharge and stabilize the system, for a total operational impact of approximately six hours,” she said.  The district estimates that the leak lasted about 24 hours. … ”  Read more from the Marin Independent Journal.

Mountain View fined $1.2M for sewage pollution in creek

“Mountain View is facing nearly $1.2 million in civil penalties after a judge ruled on March 31 that the city has been violating federal law by allowing raw sewage to get into Stevens Creek through its stormwater system, posing serious health risks.  U.S. District Judge Edward Davila fined the city for failing to comply with the requirements of permits that are mandated by the Clean Water Act, which regulates the discharge of waste into U.S. waters and sets quality standards. Davila also found Sunnyvale to be in violation of the law, and fined it the same amount as Mountain View. The penalties will be paid to the federal government.  “The violations here are serious and long-running,” Davila wrote in a March 31 court order. “They involve actual pollution — not just paperwork violations — that can pose public health risks.” … ”  Read more from San Jose Spotlight.

California announces reopening of Chinook salmon fishery in Monterey Bay for the 2026 season

“The California Department of Fish and Wildlife announced that Monterey Bay—part of the Central Coast region, which spans from Pigeon Point south to the Mexico border—will open to recreational salmon fishing on April 11. For the first time in four years, the region is also expected to reopen to commercial fishing sometime in May.  It’s highly anticipated news following years of consecutive closures tied to low population counts. The commercial fishing season for Chinook has been closed since 2022, and the recreational fishing window, while open last year for the first time since 2022, was limited to short periods in June, July and September.  Regional harvest guidelines for sport fishing set a maximum of 21,000 Chinook salmon total—also known as King Salmon. Fishing dates and guidelines for commercial salmon fishing have not yet been released.  “We’re still on a quota-based fishery, meaning there’s a total harvest limit, so when we reach that number, it’s gonna end,” says Tim Obert, a fisherman based in Santa Cruz who serves on a number of salmon groups, including the California Salmon Council and the California Advisory Committee for Salmon and Steelhead Trout. … ”  Read more from Monterey Now.

New wetland brings life to L.A.’s industrial river corridor

“After devastating floods in the 1930s, the LA River was wrapped in concrete, basically turning it into a giant 51-mile storm drain. That stopped the flooding, but it also severed ecosystems and cut Angelenos off from accessing the waterway that flows through the city.  For decades, myriad public agencies, environmental groups and nonprofits have slowly, bit by bit, been renaturalizing the river and creating new life in the corridors around it. Now, that dream is taking another step forward with a plan to transform 100 acres of land next to the LA River into a massive state park – the largest, continuous open space along the waterway.  In an industrial area of Frogtown, crews are turning an old rail yard into both a wetland and a public park. It’s about two-thirds complete and will likely open sometime next year.  “What’s happening on the river right now is a once-in-a-generation transformation of industrial land into public green space,” says Candice Dickens-Russell, CEO of the Friends of the LA River. “And that’s worth getting excited about.” … ”  Read more from KCRW.

Interior Sec. Doug Burgum on Colorado River talks: ‘Everybody’s got to make some sacrifices’

“Interior Secretary Doug Burgum said Monday that Arizona and the other states that use Colorado River water need to make sacrifices as they divvy up a shrinking but crucial resource.  The seven Colorado River Basin states are working under interim guidelines that were implemented in response to drought conditions in 2007 and expire at the end of 2026. The original compact dates back to 1922.  “It was made during the time when it was a wet cycle. There was more water to distribute. So, everybody’s got to make some sacrifices. Use that word, that’s the key word,” Burgum told KTAR News 92.3 FM’s The Mike Broomhead Show. ,,, “It’s one of the worst years in 20 years in terms of spring runoff. And it’s going to require everybody to dig in and take bigger cuts than they want, and we haven’t reached that spot yet,” said Burgum, who was planning to visit Saguaro National Park outside Tucson later Monday. … ”  Read more from KTAR.

Interior secretary says ‘nobody will be happy’ with Colorado River decision

“U.S. Interior Secretary Doug Burgum, pressed Monday to spell out how he’ll handle the Colorado River’s water crisis, wouldn’t get specific but said repeatedly that “nobody will be happy” with how his department will split a rapidly dwindling supply of river water among the seven states, including Arizona, that want a piece of it. Speaking at a roundtable in the Tucson area populated by a host of public lands industry leaders and University of Arizona President Suresh Garimella, Burgum pledged to hand down a decision this month on the first of two crucial, divisive issues his office is confronting regarding the river.  That decision will be how much water the Interior Department’s Bureau of Reclamation will release from its upstream reservoirs in the four Upper Colorado River Basin states to head off a potential calamity in which Glen Canyon Dam, forming the boundary between the Upper and Lower Basins, would no longer receive enough water to continue generating electricity that serves customers in seven Western states. … ”  Read more from the Arizona Daily Star.

Water woes: Colorado River getting less snow, sending projections for Lake Mead lower

“Forecasts keep going from bad to worse for water in the West, and a new report released Friday brought more bad news for the outlook at Lake Mead.  Experts are now projecting the Colorado River will bring just over a third of the normal amount of water to Lake Powell from April through July as snowpack levels hover around their lowest levels during the drought that began in 2000.  A report released at mid-month from the U.S. Bureau of Reclamation, which is responsible for dam operations along the Colorado River, showed Lake Mead declining even further than projections showed last month. The nation’s largest reservoir is currently 34% full, but water from this year’s snowpack won’t be enough to keep it there. … ”  Read more from KLAS.

Commentary: AI is not draining the Colorado River. I measured it.

Dr. Len Necefer writes, “People are worried about Artificial Intelligence (AI) and its use of water. If you care about the Colorado River, if you have watched Lake Powell’s water level drop and Lake Mead shrink, and have felt the dread of living in a place that is running out of its most essential resource, then hearing that a new technology is guzzling water hits a nerve. It should. The instinct to protect what is disappearing is a good one. But it turns out that AI isn’t as dire a threat to our water as people may think.  I work on the Colorado River water for a living as a filmmaker and storyteller. I have a PhD in engineering and public policy. I am Diné. The threats to the river are not abstract to me; they are very real. So earlier this year, I decided to quantify something that has been missing in the conversation about AI and water: I measured my own AI water use. … ”  Read more from Outside Magazine.

Why scientists still use a milk scale and antique aluminum tubes to track Colorado’s record-low snowpack

“On an unseasonably warm morning in late March, Brian Domonkos parked a government-issued truck at the base of Horseshoe Mountain, a nearly 14,000-foot-tall peak outside Fairplay, Colorado.  A monthly trip each winter to this spot is part of Domonkos’ job as the supervisor of the Colorado Snow Survey, a long-running federal program overseen by the U.S. Department of Agriculture. Since 1967, government researchers have tracked snow levels at the site — called a manual snow course — to predict runoff for farmers and water managers.  The USDA’s Natural Resources Conservation Service maintains around 80 similar survey sites in Colorado and more than 1,100 nationwide. Some of those survey sites date back to the 1930s. The methods to record snow haven’t changed much either, relying on some of the same old-fashioned tools put into practice nearly a century ago.  It’s now possible to estimate snowpack using satellites or automated weigh stations. Results from the long-running snow course network, however, have drawn growing interest as a severe drought bears down on the Western U.S. As the oldest dataset, it alone can show whether current conditions are unprecedented or if past dry years might offer an analog to help predict future runoff. … ”  Read more from Colorado Public Radio.

Trump’s budget proposes massive cuts for climate and environmental programs

“President Trump’s annual budget request to Congress continues his administration’s defunding of climate change programs, environmental protection and renewable energy, slashing the budgets of the Environmental Protection Agency, the National Oceanic and Atmospheric Administration and the Federal Emergency Management Agency.  The spending plan for fiscal 2027 “builds on the President’s vision by continuing to constrain non-defense spending,” wrote Russell Vought, director of the Office of Management and Budget, in a foreword to the 92-page document, which includes an historic, $1.5 trillion defense budget, an increase of 44 percent.  EPA spending would be cut in half under Trump’s proposal, released Friday, and grants from the agency would be slashed by $1 billion.

A new era of industrial logging looms

“For the last 25 years, 58 million acres of American forest have had no new roads, no logging equipment, and no reason to appear on anyone’s industrial map. This year that is changing — and much faster than most people realize. The 2001 Roadless Area Conservation Rule has functioned as a safeguard for some of the most secluded and pristine lands in the Western U.S, prohibiting the construction of roads as well as timber harvesting on 30% of the acreage managed by the U.S. Forest Service. These pockets have remained as negative space shaded in green on maps of North America and have resisted change as development has impacted everything around them. The Roadless Rule was a boundary that defined where industrialization stopped and where nature began.  On June 23, 2025, Secretary of Agriculture Brooke Rollins announced the intent to rescind the rule entirely. As of 2026, the process has moved into its most critical phase; the U.S. Department of Agriculture has announced an imminent release of the draft environmental impact statement and a formal proposed rule this spring. This release triggers a final public comment period before a definitive decision is expected in late 2026. … ”  Read more from High Country News.
