Bridging the gap between new climate science and water planning in California

“The snowpack that supplies about one third of California’s water needs historically peaked in April—but the state can no longer count on this natural water storage as the world warms. This winter is a perfect example. Precipitation was near average but the winter was so warm that much of it fell as rain, so the snowpack was sparse to begin with. Then a record heat wave in March melted so much snow that when the state measured it in April, barely any was left at the survey site.  The latest climate change research shows that the future of water in California is changing in unprecedented ways. As seen this past winter, snowpacks will shrink as temperatures rise, shifting precipitation from snowfall to rainfall. Atmospheric river storms will be more powerful and hit the state in clusters, saturating the ground and exacerbating the risk of flooding. Swings between drought and deluge will sharpen, intensifying climate extremes.  “Our future climate will not be like our past,” says Jayantha Obeysekera, who directs the Florida International University’s Sea Level Solutions Center and is a member of the Delta Independent Science Board. “We need to begin considering potential future conditions in our planning.” … ”  Read more from Robin Meadows at Maven’s Notebook.

How the strongest storm on Earth became a warning sign for a potentially historic El Niño

El Niño (left) and La Niña (right) are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth about every 3-7 years, and can affect temperature and precipitation across the United States and other parts of the world. Figure by NOAA.

“Super Typhoon Sinlaku, which will soon make landfall on American islands in the western Pacific with winds near 180 mph, is a catastrophic storm.  How did it become so strong so quickly? The short answer is that it is a product of an overheated ocean. The implications of this are even more interesting, or arguably alarming: Because it is so powerful, it is now helping push that heat across the Pacific toward what could be the strongest El Niño in a generation.  Sinlaku went from a tropical depression to a Category 5 super typhoon in roughly 72 hours, intensifying by 75 mph in a single 24-hour period. That kind of rapid intensification requires extraordinary oceanic fuel, and the western Pacific had plenty to spare. … ”  Read more from the San Francisco Chronicle.

The West’s snow drought meant record dryness — but also record flooding

“Mountain snowpack is the West’s largest reservoir, providing water for 100 million people and diverse ecosystems. The amount of water stored in the snowpack historically peaks around April 1. But this year, the snowpack in many places was absent, or nearly so, by then — the lowest level in the 45 years since automated measurements began.   A stubborn high-pressure ridge contributed to the snow drought by shunting winter storms north to Canada in January. But the main culprit, according to the nonprofit Climate Central, was exceptional heat from climate change, which also caused a spring heat wave that decimated what snow there was at a time when other dry winters have seen “miracle March” snowstorms. … ”  Read more from High Country News.

California ski resort extends its season after a major spring snowstorm

“A spring storm dumped more than than 3.5 feet (1 meter) of snow in California’s eastern Sierra Nevada, briefly closing a key interstate and extending the ski season at Mammoth Mountain.  The weekend storm came just weeks after a March heat wave melted much of California’s snow, forcing many ski resorts to close. More snow was possible Monday.  On April 1, the Sierra snowpack, which provides one-third of California’s water, stood at just 18% of average, a reading in the mountains near Lake Tahoe found. It was the second-lowest mark for that date on record.  The UC Berkeley Central Sierra Snow Lab reported 42.5 inches (53.5 cm) between Friday and Sunday, which “has been great to create a late-season snowpack. ”  “Unfortunately, record warm temps this winter means that we’re still well below average for the water year,” the lab said on social media. … ”  Read more from the Associated Press.

This simple metal tube helps scientists predict drought before it happens

“On a snowy February morning, Toby Rodgers strapped on a pair of snowshoes and trudged across a snowy field in Washington’s Cascade mountains. Rodgers, a hydrologist for the U.S. Department of Agriculture’s Natural Resources Conservation Service, had traveled into the mountains that morning to sample snow. He had also brought along something unusual looking: a long aluminum tube, with a sharp serrated bit on the end.  When he reached his destination, Rodgers carefully positioned the tube in front of him, then quickly drove the tube into the ground. Then, he pulled the snow-filled tube out of the ground, and weighed it on a spring scale. From this simple measurement, Rodgers could get a sense of how much snow was in the mountains — and how much water might be in the rivers, lakes, and reservoirs downstream when it melts in the summer.  The tube that Rodgers used is called the Church Sampler. And while it’s super-simple and low-tech, it’s arguably one of the most influential devices ever invented for predicting drought and managing water. … ”  Read more from Grist.

Sport and commercial salmon fishing to open on California ocean waters this year, subject to quotas

“California ocean waters will open to recreational and commercial salmon fishing this year, but are subject to a new quota season that halts fishing once the number of Chinook Salmon reaches a predetermined number to ensure that enough salmon return to the Sacramento, Klamath and coastal watersheds this coming fall.  The Pacific Fishery Management Council (PFMC) at its April 7 to 12 meeting ending Sunday in Portland, Oregon, finalized the sport and commercial fishing seasons in the ocean off the West Coast.  Recreational salmon fishing already opened on Saturday, April 11, from Pigeon Point south to the Mexican border, but the seasons in the rest of California were made official over the weekend. … ”  Read more from the Daily Kos.

California reopens salmon fishing, but Crescent City fishermen still shut out

“The Pacific Fishery Management Council will allow commercial fishing for Chinook salmon off California’s coast after a three-year ban aimed at helping populations recover from drought.  Recent signs suggest salmon populations are rebounding, said California Department of Fish and Wildlife information officer Steve Gonzalez.  “Salmon are on a three-year cycle, so the three years where the fishery was closed kind of reflects the three years prior that there was a drought,” Gonzalez said. “What we’re seeing now is the first year of a wet winter, and then other policies that we changed and improved on.” … But fishermen in Crescent City aren’t celebrating. Commercial salmon fishing is remains prohibited within protected areas, including the Klamath Management Zone, which covers Crescent City and Eureka. … ”  Read more from Jefferson Public Radio.

Hazardous gravel mine development puts San Joaquin as #2 on America’s Most Endangered Rivers® List of 2026

“American Rivers is today announcing the San Joaquin River as one of America’s Most Endangered Rivers® of 2026 due to a 600-foot-deep blast mine proposed alongside it, threatening its flows, water quality, and the people and wildlife that rely on it.  The San Joaquin River is the water source for 30 million Californians, supports nearly half of the state’s $61 billion agricultural economy, and is the prime habitat for Chinook salmon and Steelhead trout.  This river makes life in our state possible,” said Patricia Flores, California Central Valley associate director for American Rivers. “A mine of such a proposed magnitude could push the San Joaquin to the edge of collapse, and once that damage is done, it is done. Why risk such an important waterway that millions depend on?”  The global gravel mining company CEMEX seeks a 100-year permit for the mine, which would divert water from the life-sustaining San Joaquin River to a quarry site, potentially exposing the water supply to hazardous mining pollution. … ”  Read more from American Rivers.

Report: California has largest flood coverage gap in US

“California has one of the largest flood insurance coverage gaps in the country, a new report shows.  Neptune Flood released a new report showing residential flood insurance penetration across the state is 1.4%, despite 2.3 million properties facing flood risk over the next 30 years.  The report, California Underwater: A Blind Spot in the Golden State, shows flooding from atmospheric rivers, urbanization, aging infrastructure, and post-wildfire conditions are a growing threat to California homeowners.  Flood modeling shows that more than 2.2 times as many properties (600,000 additional properties) are at substantial flood risk as depicted in flood maps from the Federal Emergency Management Agency.  The top 10 California counties account for nearly two-thirds of all National Flood Insurance Program losses since 1978, yet only 2.7% of residential properties in those counties carry flood insurance, according to Neptune Flood. … ”  Read more from the Insurance Journal.

Hydropower generation expected to recover despite snow drought in the West

“In our April Short-Term Energy Outlook (STEO), we expect U.S. hydropower generation will increase by 5% in 2026 but remain 1.8% below the 10-year average following snow drought conditions in some states. Hydropower generation in 2025 increased to 245 billion kilowatthours (BkWh), about 4 BkWh more than the record-low generation year 2024. In 2026, we expect generation will be 259 BkWh, which would represent 6% of U.S. electricity generation.  Seasonal precipitation in the form of rain and snowpack accumulation are the two main factors that help predict water supply and hydropower generation. Seasonal precipitation influences soil moisture, and moister soil helps to preserve the snowpack, which in turn acts as a natural reservoir. … We forecast hydropower generation in California to be 28.5 BkWh in our April STEO, which is 6% less than last year’s generation but 15% more than the 10-year average. … ”  Read more from the US Energy Information Administration.

Wildfires killed nearly 20% of the world’s giant sequoias. How crews are racing to save the rest.

“Five years ago, a tragic and depressing environmental story unfolded when thousands of giant sequoia trees, an iconic California species that tower 300 feet high and can live for 3,000 years, were killed during multiple large wildfires that roared across the southern Sierra Nevada.  The fires in 2020 and 2021 at Sequoia National Park, Sequoia National Forest and other areas burned with unprecedented intensity, killing nearly 20% of the world’s giant sequoias, and exposing the growing vulnerability of the most massive trees on the earth.  “It was heartbreaking,” said Kevin Conway, state forests program manager for Cal Fire, the state’s primary firefighting agency. “You can’t help but ask, what could I have done? What should I have done? Could I have prevented this?” … ”  Read more from the San Jose Mercury News.

California bill aims to ban PFAS pesticides

“California Assembly Bill 1603 (AB 1603) seeks to ban pesticides containing per- and polyfluoroalkyl substances (PFAS). The legislation was introduced by Assemblymember Nick Schultz (D-44).  Specifically, AB 1603 would prohibit the California Department of Pesticide Regulation from registering a pesticide that has not previously been registered by the department and contains intentionally added PFAS as active, adjuvant, or inert ingredients. If passed as-is, the legislation would classify PFAS as restricted materials by July 1, 2028. The manufacture and sale of pesticides containing certain PFAS would be prohibited by January 2030 and all PFAS pesticides would be prohibited by January 2035. … ”  Read more from Food Safety Magazine.

Trust, land, and community under the Sustainable Groundwater Management Act

Anna Kathawalla writes, ” … California agriculture is tied to the Sustainable Groundwater Management Act (SGMA), a bill passed in 2014 with the goal of reducing groundwater overdraft throughout the state, an agriculture-driven environmental hazard that is depleting aquifers and causing subsidence. The main tension behind SGMA is that the act is expected to cause between 500,000 to 1 million acres of San Joaquin Valley agricultural land to come out of production before 2040, and the act does not come with a built-in support system to help farmers figure out what to do with their land when agriculture is no longer an option. Neither SGMA nor the Valley farmers who it’s hurting the most are at fault—farmers are simply employing decades old agricultural practices to meet national food demand and SGMA is simply trying to preserve the state’s water resources.  AW is one of the first farmers to feel the impacts of SGMA fully realized on his land. SGMA, although passed more than a decade ago, is just now taking hold across the state, and farmers are now faced with the difficult choice of farming under restrictions and the potential of facing fines, or not farming at all. … ”  Read more from Common Dreams.

Middletown Advisory Council ponders whether they can save the creeks and fish from perennial drought

“Newly seated Chair Charles Morse, appealed to the MATH Council on April 9 whether they had the political will and funding to restore the South County creeks and fish habitats after years of drought and assume more responsibility as thoughtful stewards.  “What can we do to revive it- we got to do something about people on the creek; they run out of water constantly,” Morse said. The County seems to love to take money for permits for big Ag things, let’s say cannabis, for instance and it sucks a lot of water out and then there’s no water in the Santa Lina Creek. And we know because the water doesn’t make it from June through September to Perry’s Bend. I looked at the 2025/26 Local Area Plan and thought if I can find the money and energy, maybe revive the town.”  But it is not just finance that is needed but the water as well. The Callayomi Water District is the go-to utility in the area, but they are not obligated to get anybody in the south county any water. “They are a business and are obligated to get water to where their pipes are, and their pipes don’t go anywhere near there,” Morse said. … ”  Read more from the Lake County Record-Bee.

Tahoe/Truckee sees 3.5 feet of snow, More weather on the horizon

“A storm dumped fresh snow across the Sierra Nevada on Sunday, quickly erasing March’s dry spell and delivering a strong late-season boost to the mountains. Conditions made for a prime day of skiing and snowboarding in Tahoe.  At higher elevations, Palisades Tahoe and Kirkwood Mountain Resort reported roughly 3.5 feet of new snow. According to OpenSnow forecaster Bryan Allegretto, the storm pushed April’s snowfall total to around 70 inches so far, marking the snowiest April since 2022. The season total now sits at approximately 348 inches, or about 88% of the seasonal average for this time of year.  Looking ahead, forecasters expect a stretch of calmer conditions through midweek, with sunny skies and cold temperatures persisting through Wednesday. A weak system could bring light rain and snow showers Wednesday night into Thursday, followed by dry weather returning Friday and Saturday.  Despite the brief break, winter is not necessarily finished for the Sierra. … ”  Read more from the Tahoe Daily Tribune.

Fix for what ails Tahoe is costly, lawmakers learn

“Preserving Lake Tahoe’s clear, blue water depends in large part on reducing vehicle travel. The basin, however, lacks reliable and efficient transit for residents, tourists, and commerce, and a funding source to fix it, say experts who testified Friday before the Nevada Legislative Committee for Review and Oversight of the Lake Tahoe Regional Planning Agency.  “It’s not the people coming to Tahoe that place the largest strain on this fragile ecosystem,” former Tahoe Regional Planning Agency board member John Friedrich told lawmakers. “It’s the cars they travel in.” Lake Tahoe is surrounded by State Route 28, which is snarled, especially in the summer, by a mix of traffic from 55,000 residents and some 25 million visitors a year, according to studies commissioned by the TRPA.  Vehicles emissions, microplastics from tires, and dust from trucks and autos are among the factors preventing Tahoe from reaching a visibility goal of 97 feet deep.  “As we say in Tahoe, ‘what happens on the land affects the lake.’ It’s all connected,” observed Tahoe Regional Planning Agency Executive Director Julie Regan. “All that TRPA endeavors to achieve is in service to our environmental threshold standards.” … ”  Read more from the Nevada Current.

Yuba Water Agency launches multi-phase project to restore damaged powerhouse

“A major infrastructure failure at Yuba Water Agency’s New Colgate Powerhouse has triggered a long-term recovery effort expected to take years, after a massive penstock rupture released thousands of gallons of water and caused extensive damage along the North Yuba River.  According to the Yuba Water Agency, the rupture occurred Feb. 13, when a 14-foot-diameter penstock pipe above the powerhouse failed, sending an estimated 400 acre-feet of water cascading down a hillside.  The sudden release caused severe erosion and damaged the New Colgate Powerhouse, nearby electrical switchyards and portions of Lake Francis Road, officials said.  Authorities stated that the facility will be unable to generate electricity for the foreseeable future. … ”  Read more from Fox 40.

Construction begins on Iron Canyon Fish Passage Project, unlocking miles of critical salmon habitat on Big Chico Creek

California Trout (CalTrout), the Mechoopda Indian Tribe, the Big Chico Creek Ecological Reserve (BCCER), and the City of Chico, today announced the start of the instream  phase of construction on the Iron Canyon Fish Passage Project on Ótakim Séwi (Big Chico Creek) in Upper Bidwell Park. In 1956, concrete and rebar fish ladder weirs were constructed through a rockfall barrier in Iron Canyon—a narrow bedrock gorge deep within Bidwell Park. The purpose was to help steelhead and spring-run Chinook salmon reach miles of critical cold-water spawning and holding habitat during low water years. Over time, this fish ladder has become nonfunctioning, causing steelhead and salmon to hold downstream where water temperatures are too warm for their survival. The Iron Canyon Fish Passage Project will remediate the barrier, restoring access to 8.5 additional miles of habitat and returning a piece of a watershed that has sustained people, wildlife, and ecosystems for thousands of years. … ”  Read more from Cal Trout.

San Francisco Bay is evolving into a death trap for gray whales

“Like many gray whales, a young male called Denali likely wintered in the balmy waters off Baja before propelling northward each spring to fill his belly in the Arctic. Marine scientists saw this whale, named after his white spot shaped like Alaska, every year between 2020 and 2024. But last April, partway through his 10,000-mile annual migration, Denali died in San Francisco Bay.  Local scientists from the Marine Mammal Center and California Academy of Sciences, who examined Denali’s body near the Golden Gate Bridge, believe that a vessel probably struck him. In 2025, Denali was one of 21 dead gray whales, a record-high number for the Bay Area.  The first research to document the fatalities, published in the journal Frontiers in Marine Science on Sunday, found that at least 18% of the gray whales spotted in San Francisco Bay from 2018 to 2025 died. Vessels killed at least 40% of them, and many others starved, the study found. … ”  Read more from SF Gate.

Carpinteria’s $90 million water recycling project—a first for Santa Barbara County—will break ground in May

” … the memory of scarcity lingers. During the drought of 2012 to 2018, Cachuma shrank to a pond in a bed of cracked earth. Supplies from the state aqueduct — like Cachuma, a source of “imported” water for the South Coast—dwindled to five percent of entitlements. Water basins were pumped to historic lows.  That’s when the push for “locally-controlled” water supplies began. In 2017, the City of Santa Barbara reactivated its desalination plant at a cost of $72 million. In 2021, the Montecito Water District signed up to pay $33 million of that amount in return for a 50-year supply of city water.  Now, an even more costly water project is about to break ground in the Carpinteria Valley—a $90 million system for converting wastewater to drinking water. It’s a joint project of the valley’s water and sanitary districts, and it’s the first of its kind in the county. … ”  Read more from the Santa Barbara News-Press.

Westside’s solar footprint grows along I-5

“In the past six months, about a dozen huge utility-scale solar projects have launched permitting requests on thousands of acres of former farmland near I-5, the Valley’s driest region, where farmers have been hardest hit by water scarcity worries and SGMA regulation.  Many are wondering how they will be able to pay their bills in the future. For many Kern, Kings and Fresno county landowners, harvesting solar energy is the most attractive answer.  While the current administration in Washington has downplayed the benefits of renewable energy, even calling it a scam, farmers are watching missiles fly over the Middle East, where fossil fuels are being fought over. Meanwhile there are no missiles flying over I-5. Now it turns out that none other than the United Arab Emirates is investing here — not in oil but in solar. … ”  Read more from the Hanford Sentinel.

Colorado River Basin states could learn from what we developed in Australia

Mike Young writes, “No one should be surprised that Colorado River Basin states have struggled to renegotiate the Colorado River Compact.  The compact’s framework was drafted in 1922, back when Henry Ford was still selling Model T Fords. Developed to protect gold miners, the West’s “first-in-time, first-in-right” water allocation system is even older.  Colorado Basin water users deserve a modern water-right and allocation system — one that can be confidently described as robust enough to withstand the test of time.  For now, the 1994 Water Treaty with Mexico could be left as it is.  A state-of-the-art compact would reserve enough water to maintain a base flow and then allocate the remaining water to states in the form of a defined share of inflows and then onto water-right holders as shares. In order to allocate shares to right holders, each section of the river would need to be divided into a high-security pool, a general-security pool and a low-security pool. … ”  Read more from the Colorado Sun.

Scientists finally know where the Colorado River’s missing water is going

“For years, water managers have been puzzled as the Colorado River kept delivering less water than expected—even when snowpack levels looked promising. New research reveals the missing piece: spring rain, or rather, the lack of it. Warmer, drier springs mean plants are soaking up more snowmelt before it can reach rivers, fueled by sunny skies that boost growth and evaporation. In fact, this shift explains nearly 70% of the shortfall, tying the mystery directly to the long-running Millennium drought. … ”  Read more from Science Daily.

Utah’s snowpack situation is a piece of a larger Western problem

“Nearly 60% of Utah remains in severe or worse drought after the state’s snowpack peaked about a month prematurely at its lowest level since daily collection began in the 1980s.  Snowpack on April 1 is the lowest since data was first collected in 1930, federal hydrologists added. This signals trouble for smaller reservoirs that rely on snowpack to refill each year, as well as for other reservoirs in central and southern Utah that suffered a difficult season last year.  It also opens the state up to other water challenges, earlier wildfire conditions, agricultural damage and possibly fewer recreation opportunities this summer. That requires early planning and coordination to navigate the hurdle, said Joel Ferry, director of the Utah Department of Natural Resources. … ”  Read more from KSL.

“As Coloradans grapple with a record low snowpack heading into summer, the super El Niño and strong monsoon season in the forecast could provide some late summer relief.  Colorado’s weather is impacted by everything from temperature changes in the Pacific Ocean to pressure patterns over Texas — not to mention rising temperatures around the globe. This year’s La Niña conditions, created by cooler water temperatures in the Pacific, should have brought snow to Colorado’s northern mountains. Instead, the state ended the winter a month early with record hot days and a rapid snowmelt, prompting drought restrictions and water cutbacks around Colorado.  As of last week, the La Niña is over and the odds are increasingly good for a super El Niño later in 2026 — a climate pattern that has historically brought wetter winter conditions to Colorado, according to the National Weather Service. … ”  Read more from the Colorado Sun.

Recent examples include a California community blocking a new datacenter outright and a Republican-leaning Wisconsin town passing the nation’s first anti-datacenter referendum, rejecting a Trump-backed project. The opposition is driven by concerns over water usage, power consumption, and noise, with residents feeling the facilities will consume significant local resources without delivering meaningful benefits. … ”  Read more from National Today.

Greens see chance to protect species in ‘God Squad’ fight

“The Trump administration’s move to exempt oil and gas activities in the Gulf of Mexico from endangered species considerations could hand environmentalists a public engagement opportunity, although one they would prefer not to have.  The use of the so-called God Squad last month to grant a more than 600,000-square-mile exemption for the oil industry puts the spotlight on the kind of charismatic species — whales and sea turtles — that not only conservationists but the general public hold dear. In particular, it highlights the plight of the Rice’s whale, which has only a few dozen of its kind left.  “This action by the Trump administration may prove to be a galvanizing moment for a whole new generation of advocates and voters who support the Endangered Species Act and the wildlife and ecosystems it protects,” said Ben Greuel, national wildlife campaign manager at the Sierra Club. … ”  Read more from E&E News.
