It is wild how often cities used to burn down. So when fires ripped through LA at the beginning of 2025, we wondered: are urban firestorms back? In 1871, nearly a third of Chicago burned down. In 1889, 25 blocks of Seattle went up in flames. Modern buildings and firefighting solved the problem. So, how is this happening again? And why is it getting worse? To find out, we went to LA while the fires were still burning. Our crew was on the ground from day one. We interviewed top fire officials and leading scientists. And, we learned exactly what went wrong in LA – and the one thing that could stop these unstoppable fires.  Click here to watch video.

March storms help Sierra snowpack inch closer to normal for this time of year

“After days of snow falling in the Sierra, the winter season is inching closer to recovering from a dry start to the year.  According to snow sensor data from the California Department of Water Resources, the statewide Sierra snowpack fell to 66% of average on Jan. 30.”

California will get a break from storms soon. But the rainy season isn’t over yet

“The last wet weather system of the week is poised to swing across Northern California on Wednesday, but it won’t pack much of a punch. Afternoon and evening rain showers are unlikely to add up to more than a tenth of an inch in San Francisco, while parts of the Bay Area could remain completely dry. Light snow should add another few inches to the northern Sierra Nevada snowpack, but the system will be starved of moisture by the time it reaches Lake Tahoe.  Beyond Wednesday, a weeklong dry stretch is likely in store for the Bay Area. … ”  Read more from the San Francisco Chronicle.

Sites Reservoir allocated an additional $134 million in federal funding

Proposed location of Sites Reservoir

“Last week, the Sites Reservoir Project (Project) received $134 million in federal funding from the Water Infrastructure Improvements for the Nation Act (WIIN Act), which provides funding to improve water infrastructure throughout the United States.  “The continued bipartisan support for Sites Reservoir shows we all agree—we desperately need more water storage in California to prepare for the future,” said Fritz Durst, Chair of the Sites Project Authority Board of Directors. “This announcement brings the WIIN Act funding designated to Sites Reservoir closer to the level the Authority and Reclamation have been working to secure and we’re grateful to our federal partners for helping to advance this critical project closer to construction.”   With this investment, the Project has been designated a total of $780.15 million in federal contributions to date. The Sites Project Authority will continue to work with the Bureau of Reclamation (Reclamation) on achieving their 16% participation goal as space in the reservoir becomes available and sufficient funds are appropriated to the Project. … ”  Read more from the Sites Project JPA.

New court guidance on rights to use captured water/percolating groundwater

“On March 14, 2025, the Court of Appeal for California’s Fifth Appellate District issued its decision in Sandton Agriculture Investments III v. 4-S Ranch Partners, 2025 S.O.S. 659. That case provided guidance on ownership of captured water and percolating groundwater.Sandton Agriculture Investments III (Sandton) acquired real property from 4-S Ranch Partners (4-S) through foreclosure proceedings related to 4-S’s bankruptcy. A dispute then arose as to whether Sandton’s acquisition of the property included the 500,000 acre-feet of groundwater stored in the land under the property. 4-S claimed that it still owned that water as its personal property. The 500,000 acre-feet of water was valued at $200 million in 2020, and 4-S claimed the value had risen to $600 million by 2022. … ”  Read more from Nossaman.

California water agencies oppose Trump-proofing bill

“The leading trade group representing California’s public water agencies came out Monday against a bill meant to protect the state from Trump administration rollbacks.  What happened: The Association of California Water Agencies adopted an “oppose” position to Sen. Ben Allen’s SB 601, which would clarify state law to reclassify all waters that were previously defined as “waters of the state” prior to the Supreme Court’s 2023 Sackett v. EPA decisionACWA senior policy advocate Soren Nelson said in an email the group has “serious concerns with SB 601, as it would needlessly complicate the state’s regulatory framework for protecting water quality, lead to frivolous litigation, and almost certainly translate into higher water bills for Californians.” … ”  Read more from E&E News (subscription required).

Diane Papan introduces legislation to prevent politically motivated water releases in state

“Legislation to prevent the unnecessary and harmful discharge of California water from reservoirs under false pretenses was introduced by Assemblymember Diane Papan, D-San Mateo. Assembly Bill 1146 would prohibit the release of California’s stored water if it is carried out under knowingly false or fraudulent representations regarding the purpose or intended use of the water. The legislation would empower the State Water Resources Control Board to issue interim relief orders to stop unlawful water releases and ensure that California’s water, its storage and planning efforts remain protected from external political interference. The bill would provide that any person who violates these provisions would be guilty of a misdemeanor, according to Papan’s office. … ”  Read more from the San Mateo Daily Journal.

Supreme Court waves goodbye to Clean Water Act end-result requirements

“On March 4, 2025, the US Supreme Court issued its decision in City and County of San Francisco v. Environmental Protection Agency, 145 S.Ct. 704 (2025), which held that while the Clean Water Act (CWA) authorizes the inclusion of narrative (non-numeric) criteria in National Pollutant Discharge Elimination System (NPDES) permits, it does not authorize “end-result” requirements. End-result requirements are provisions in an NPDES permit that do not specify what actions a permittee must take or refrain from taking. Instead, end-result requirements place the responsibility for achieving specific water quality results in the receiving water body on the discharging facility itself, rather than specifying the actions the facility must take to comply with water quality standards. The Court emphasized that the Environmental Protection Agency (EPA) is responsible for determining and specifying the necessary steps to ensure compliance with water quality standards. … ”  Read more from Latham Watkins.

Reducing flood risk through Forecast-Informed Reservoir Operations in California

“A new report released on March 13, 2025, shows that changes to reservoir operations at Lake Oroville and New Bullards Bar Reservoir in California can further reduce flood risk for communities along the Tuba and Feather rivers during extreme atmospheric river storm events and potentially benefit water supply during drier river periods.  The approach, known as Forecast-Informed Reservoir Operations (FIRO), uses improved monitoring, weather and runoff projection to build more flexibility and efficiency into reservoir operations.  The California Department of Water Resources (DWR) and Yuba Water Agency partnered with the Center for Western Weather and Water Extremes (CW3E) at UC San Diego’s Scripps Institution of Oceanography and the U.S. Army Corps of Engineers’ Engineering Research and Development Center to evaluate if FIRO could be implemented at both reservoirs to reduce downstream flood risk without negatively impacting water supplies. … ”  Read more from Stormwater Solutions.

How the Klamath Dams came down

Excavators and other equipment disassemble Iron Gate Dam on the Klamath River. The removal of Iron Gate and other dams will reopen hundreds of miles of historic habitat to salmon. A new monitoring program will track their return. Photo credit: Bob Pagliuco/Office of Habitat Conservation.

“Last year, tribal nations in Oregon and California won a decades-long fight for the largest dam removal in U.S. history.  This is their story.  At 17 years old, Jeff Mitchell couldn’t have known that an evening of deer hunting would change his life — and the history of the Klamath River — forever.  Over Thanksgiving week in 1974, Mitchell and three friends were driving home to Klamath Falls, Oregon, when their truck hit black ice, careened off the road, crashed into a ditch, and rolled over violently, throwing Mitchell from the vehicle and knocking him unconscious.  … If not for the black ice that nearly killed him, Mitchell might never have helped launch one of the biggest victories for Indigenous rights and the contemporary environmental movement in North American history: the demolition of four hydroelectric dams on the Klamath River, a degraded 263-mile waterway that winds through Mitchell’s ancestral homeland and that of four other Indigenous nations. … ”  Read more from Grist.

Lake County calls for accountability in PG&E Dam Removal

“The fight to save Lake Pillsbury took center stage at the February 25, 2026, Lake County Board of Supervisors meeting, as officials urged PG&E and state and federal agencies to reconsider the planned decommissioning of Scott Dam. Frustrated by years of exclusion from key water policy discussions, Supervisors Eddie Crandall and Bruno Sabatier warned that losing the reservoir could have dire consequences—threatening water security for 600,000 people, crippling local agriculture, and increasing wildfire risks. With PG&E’s final surrender application pending, Lake County leaders are demanding answers, accountability, and a seat at the table before it’s too late.  The Lake County Board of Supervisors discussed PG&E’s plan to abandon the Potter Valley Project, and how that would affect Lake County and Lake Pillsbury. Supervisor Eddie Crandall said “There’s never been any proper discussion about what would happen if we didn’t decommission Scott Dam.” … ”  Read more from MendoFever.

Lake Tahoe: A tarnished jewel

Lake Tahoe by Nat Urazmetova.

“Lake Tahoe is an innocent victim — but there isn’t just a single villain. This alpine treasure a mile-high in the Sierra Nevada is victimized by all the problems that humans inflict on it. In this two-part series, CalMatters reveals how the billions of dollars spent on improving the health of the Tahoe region have not resolved the lake’s problems, and how regional planners have recently shifted much of their focus to promoting tourism and recreation projects. The Tahoe region, encircled by dense forests, also is one of California’s riskiest places for potentially deadly out-of-control wildfires. Fire officials told CalMatters that thousands of people could be trapped because of inadequate evacuation routes — yet developers continue to build resorts and housing in high-risk areas. … ”  Read more from Cal Matters.

The high cost of fixing Lake Tahoe

“An azure jewel set more than a mile high, deep in the High Sierra, Lake Tahoe is California’s most highly curated and micromanaged natural asset. Even among the state’s many famous landmarks, Tahoe is beloved and revered.  The 2-million-year-old lake, famed for its deep blue color, sits in a basin encircled by steep forests. Despite the region being somewhat difficult to reach, about 15 million visitors from around the world flock there every year — three times more than Yosemite National Park.  Its beauty is also its vulnerability: Buffeted by the constant tug between developing the region and preserving it, and attracting visitors while managing their impact, Lake Tahoe is showing the strain.  State and federal agencies, nonprofits and other groups have spent more than $3 billion over the past quarter century for more than 800 projects that aimed to protect and improve the lake and its environs. … But despite all of the billions lavished on Lake Tahoe, questions remain about whether all of this funding and attention have actually improved the quality of the lake and its surrounding environment. … ”  Read more from Cal Matters.

Hello nutria? California’s least-welcome invasive swamp rodents arrive in Fresno

Columnist Marek Warszawski writes, California’s most-destructive and least-welcome swamp rodents have arrived in its fifth-largest city. To be precise, they’ve arrived in the stretch of San Joaquin River that traces Fresno’s northwest border. Eight years have passed since a reproducing population of nutria was found in western Merced County — their first discovery in the state since the 1970s. Despite eradication efforts that began in March 2018, nutria have since spread north into the Delta, east into foothills along the Merced River and south into the Fresno Slough and Mendota Wildlife Area. … ”  Continue reading at the Fresno Bee.

San Joaquin County’s almond growers pinched by Trump’s tariff wars

“President Donald Trump’s tariffs are making the almond business a tougher nut to crack for San Joaquin County growers.  When Trump slapped more tariffs on China earlier this month, it didn’t take long for a round of retaliation. China answered by imposing an additional 10% on raw and manufactured tree nuts imported from the U.S. Adding the latest taxes to those China had already imposed during Trump’s first administration, the total tariff rate on all imported U.S. tree nuts now stands at 35%.  California provides 80% of the world’s almond supply, with about half of its production being exported, according to the Almond Board of California.

Seismometers provide fuller picture of Los Angeles groundwater

“A series of atmospheric rivers slammed California in early 2023, dumping as much as 300% of the historical annual average rainfall on some parts of the state. The rains replenished surface water storage above its historical average, but scientists are still unraveling how the influx of precipitation affected the state’s groundwater, which suffered from extreme drought conditions from 2020 to 2022.   In a new study published in Science, researchers used an existing network of seismic instruments to probe that question. They found that surface water, such as lakes, streams, and reservoirs, had recovered above its historical average after the winter storms. But the volume of groundwater—defined in the study as water stored more than 50 meters (164 feet) below the surface—lagged far behind. … ”  Read more from EOS.

See how drought whiplash led to California wildfires

“The devastating fires in California early this year came after a particularly unfortunate weather pattern—an exceptionally wet period of about 18 months, followed by an exceptionally dry spell. The wet duration encouraged grass and brush growth, and then the lack of rain dried it all out, priming it to catch on fire and spread quickly.  “It was a classic example of wet-to-dry whiplash,” says Daniel Swain, a climate scientist at the University of California, Los Angeles. And such whiplashes may be getting more common. “With climate change, it’s not just that we’re seeing things get drier and drier. There’s also a trend toward more variability, with wider swings between wet and dry,” Swain says.  The warming climate is leading to what scientists call the “expanding atmospheric sponge” effect. … ”  Read more from Scientific American.

‘Like someone put a blanket over the ocean’: Kelp could be among fires’ casualties

“The boat bobbed gently off Malibu’s Big Rock Beach as a trio of scientific divers wriggled into wetsuits and double-checked tanks and regulators.  Behind them unfurled a panorama of devastation from the Palisades fire a month earlier. Blackened vegetation dotted the hillsides rising above Pacific Coast Highway. Rubble and lonely chimneys littered the shore where beachfront homes once stood.  One by one, the three divers slipped beneath the surface, nets and knives at the ready. They were seeking evidence of the fire’s underwater toll, particularly its effect on a vital anchor of the coastal ecosystem: kelp.  The divers were with Kelp Ark, a San Pedro-based nonprofit seed bank that preserves and stores genetic material from West Coast kelp species. The Feb. 10 dive was their second since fire and subsequent rains injected tons of ash and debris into the ocean ecosystem.  “When we think about wildfires, we think a lot about how that impacts the terrestrial realm, how destructive it can be to the land,” said Lori Berberian, a second-year PhD student in geography at UCLA who studies the effects of wildfire on kelp abundance and habitat distribution. “But there are huge implications for the coast.” … ”  Read more from the LA Times.

Lawsuits only further complicate Arizona’s water challenges

“There are now two lawsuits against the Arizona Department of Water Resources (ADWR). The first challenges ADWR’s efforts and authority to uphold the 100-year Assured Water Supply Program, the foundation of Arizona’s thriving economy. The second would prevent homebuilding from restarting, where it has been halted due to groundwater concerns. In the end, both lawsuits pose threats to Arizona’s water and housing future.  Many are frustrated that these lawsuits will only further complicate Arizona’s water challenges, including uncertainty about how the federal government will reduce our Colorado River water after 2026.

“The Church of Jesus Christ of Latter-day Saints says it will soon save the amount of water it takes to support 3,000 homes in a given year.  This year, the church plans to install 1,800 “smart controllers” at meetinghouses across the West, including in Arizona, Idaho, Montana, Nevada, Utah and Wyoming. The new controllers are irrigation systems, including sprinklers, that adjust water output based on the weather “so that we’re most efficiently watering our plant materials,” said David Wright, landscape architect for the church’s Meetinghouse Facilities Department.  Wright said he estimates the church will save 500 million gallons of water — about 1,534 acre-feet — during the first year the smart controllers are in place. For reference, one acre-foot is about how much water two Utah homes typically use in a year. … ” Read more from the Salt Lake Tribune.

Will Colorado see drought conditions start to develop this spring?

“As winter nears its end and Colorado’s mountains get hit with the latest March snowstorm, climatologists and forecasters are predicting that the spring will bring drier weather and, in turn, lead to drought developing or deepening across much of the state.   The Feb. 28 seasonal drought outlook from the National Weather Service predicted that most of Colorado would develop drought conditions heading into May, as La Niña weather patterns predict drier — and in some areas, warmer — conditions than normal.  “That spring outlook shows a pretty high confidence of drier-than-average conditions across Colorado in the spring,” said Russ Schumacher, Colorado’s state climatologist and director of the Colorado Climate Center. “The spring tends to be pretty wet across Colorado as a whole, and so if we do have a dry spring, then things can go south pretty quickly in terms of drought — and the outlook is tilted toward those drier-than-average conditions.”  …. ”  Read more from the Aspen Times.

The nation’s chief engineers turn to nature to improve flood protection

Controlling nature by bulldozing dirt and pouring concrete has long been the guiding vision of the U.S. Army Corps of Engineers. For 250 years that ethos inspired both awe and disgust. “In my science training, the Army Corps destroyed everything. They’re the enemy,” says geomorphologist Julie Beagle, who spent much of her early career working to repair ecosystems damaged by “gray” infrastructure such as dams and levees built by the Corps. “My first boss had a sign on her desk that said, ‘Kill the Corps.’” To such critics, damaging nature was the Corps’s core competence.  So plenty of people were skeptical in 2010 when the Corps rolled out an Engineering with Nature (EWN) initiative, saying it now aspired to work with nature rather than dominate it—a dramatic change in culture and practice. … The initiative is relatively small; there are seven EWN programs sprinkled across the Corps’s 43 districts (five of which are international). But the changes convinced Beagle four years ago to leave her job at the San Francisco Estuary Institute and become chief of environmental planning for the Corps’s San Francisco district. … ”  Read more from Scientific American.

Rising seas and land-based salt pollution pose dual threats for drinking water

“Global sea levels rose faster than expected last year, largely due to warming ocean temperatures, a new NASA analysis found.  As seawater creeps further into coastlines, salt threatens to pollute the freshwater reserves that people depend on. But this brine isn’t just coming from the ocean: New research shows freshwater ecosystems are facing widespread dual threats of salt contamination from the sea and land, made worse by climate change.  Humans are a salty species, using the mineral for a vast number of reasons—from de-icing the roads during snowstorms to seasoning food.  But our salty habits, coupled with rising seas, pose major threats to human health, infrastructure, agriculture and wildlife.
