“The recent series of atmospheric rivers brought periods of heavy rain increasing runoff into Northern California rivers and reservoirs.  The U.S. Bureau of Reclamation says it’s increasing water releases from some Central Valley Project reservoirs for flood control management. This will result in rises on some rivers. These coordinated management operations are done to maximize hydropower production from Central Valley Project facilities.  In addition, the federal pumps in the Sacramento-San Joaquin Bay-Delta are operating at maximum capacity and storing water in the San Luis Reservoir to support south-of-Delta delivery to farms, communities and wildlife refuges to use during the dry season when needed. … ”  Read more from Channel 10.

Chance of strong atmospheric river storm grows, as does risk of mudslides in L.A. burn scars

“The risk is rising for a strong atmospheric river to arrive next week, possibly bringing rain that could trigger debris flows and mudslides in Los Angeles County’s burn areas.  There is now a 30% chance that “high amounts” of rain could fall between Feb. 12 and 15 in Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties, the National Weather Service said, up from the 10% chance forecast Tuesday.  The chance of moderate or low amounts of rain now stands at 30%, with a 10% chance of no rain.  “The range of outcomes is still very uncertain, but that potential for a strong, very wet system is still there,” said Ryan Kittell, meteorologist with the National Weather Service office in Oxnard. … ”  Read more from the LA Times.

CDFW partners with DWR and fishing industry to diversify salmon hatchery release strategies

“In a collaborative effort to increase the sustainability of California’s salmon populations, the California Department of Fish and Wildlife (CDFW) has partnered with the Department of Water Resources (DWR), as well as ocean and inland fishing groups to continue a pilot project aimed at diversifying salmon hatchery release strategies.  As part of a broader initiative to expand salmon hatchery release strategies, CDFW recently released more than a million fall-run Chinook salmon fry into the Feather River. These salmon fry are released shortly after hatching, which mimic the same life stage in the wild when they would swim up out of the gravel. Typically, fall-run Chinook salmon released from the hatchery are about six months old and 3.5- to 4-inches in length. This technique was first introduced at the American River at the Nimbus Fish Hatchery in 2023.  This marks the second fry release in the Feather River this year, bringing the total number of fry released to approximately 1.8 million. These releases are in addition to the Feather River Hatchery’s typical target of 6 million smolts (a young salmon that is ready to migrate from freshwater to the ocean, usually around 6 months old) as well as the additional 3.5 million smolts and sub-smolts CDFW aims to produce at the Feather River Hatchery in 2025. … ”  Read more from the Department of Fish and Wildlife.

“The disinformation about the Delta Smelt spouted out by President Trump and his Big Ag allies has deluged social media and both mainstream and “alternative media” in recent weeks.  As an independent journalist who has covered the Delta Smelt and the California water wars for the past three decades, I was intrigued when I saw a piece in San Francisco Chronicle about the federal funding for the Delta smelt being cut: www.sfchronicle.com/…  “After President Donald Trump’s recent criticism of the delta smelt — a fish he has tied to the lack of water for fighting the Los Angeles fires — his administration is planning to cut funding for a captive breeding program intended to ensure survival of the endangered fish,” reporter Kurtis Alexander wrote. Concerned about the reported slashing of the captive breeding program funding by the Bureau of Reclamation, I contacted UC Davis spokesperson Bill Kisliuk, who sent me his statement about the current status of the captive breeding program, indicating that they were hoping to get funding for the program extended past Feb. 28 … ”  Read more from the Daily Kos.

Republicans blame California policy for fueling Los Angeles fires at hearing Dems call political theater

“House Republicans blasted California’s environmental regulations as helping fuel the Los Angeles County wildfires, often using politically charged and sometimes misleading claims, as Congress on Thursday convened its first hearing on last month’s deadly firestorms. The state’s inability to clear combustible brush and trees and too little water for firefighting, both of which the critics blamed on “overregulation,” were cited as reasons that the Southern California infernos became the disaster they were. The criticism at the Republican-led subcommittee hearing echoed the recent remarks of President Donald Trump, who has taken aim at California’s policies since the fires and even threatened to withhold disaster aid if major revisions aren’t made. … ”  Read more from the San Francisco Chronicle.

GOP blames California’s policies for extent of LA wildfire damages as they debate aid bill

“A House subcommittee held a hearing on Thursday examining whether a series of state-level regulations in California have helped contribute to its growing issues with destructive wildfires that have caused billions in damage as Congress continues to debate a disaster relief bill to help the city rebuild. … President Donald Trump and other Republicans in Congress have blamed California’s Democratic leadership, particularly targeting Gov. Gavin Newsom, for mismanaging its water supply and failing to take enough preventative measures to keep fires from breaking out and spreading“One would think California would prioritize mitigation efforts to reduce the number of the strength of fires. Unfortunately, California leaders have insisted and instead prioritized often counterproductive goals, like planting trees, installing electric vehicle charging stations over equipping their communities and first responders with the tools they need to protect their citizens and livelihoods,” said Rep. Scott Fitzgerald, R-Wis., who chairs the subcommittee that held Thursday’s hearing. … ”  Read more from The National News Desk.

Gavin Newsom visited DC to lobby for wildfire aid — but left without a deal in place

“This week, Gov. Gavin Newsom headed to Washington, D.C., to persuade federal officials to approve federal disaster aid after wildfires devastated Los Angeles last month. Newsom has warmed to President Donald Trump in recent weeks, whom he praised for his collaboration with California during previous disasters. It hasn’t always been that conciliatory. Trump has referred to the governor in the past as “Newscum,” and called on him to resign immediately after the Los Angeles wildfires. Ultimately, the governor left the nation’s capital Thursday afternoon without a concrete deal in place as Republicans slammed his leadership and blamed the fires on overregulation. … ”  Read more from the Sacramento Bee.

Unscheduled water release prompts questions from Jared Huffman

“Last Friday, the Senate Environment and Public Works Committee questioned Defense Secretary Pete Hegseth after the United States Army Corps of Engineers, in accordance with the wishes of the Trump administration, directed unscheduled water releases from Lake Kaweah (the Terminus Dam) and Success Lake (the Schafer Dam) in Tulare County.  The water release occurred on Jan. 30, with the water ostensibly to be used to fight fires in Southern California; most of the water, reserved for important growing regions in central California, went into the ground.  Senator Alex Padilla, D-Calif., released a statement condemning the act as “reckless” and noted that the fires had largely been contained by Jan. 30. … ”  Read more from the Eureka Times-Standard.

These new materials could help solve drought in the Western US

“Advances in a field of research known as reticular chemistry could provide a breakthrough solution to the growing water scarcity crisis in the western United States.  Material science researchers have developed highly porous crystalline materials, known as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), capable of efficiently capturing water vapor from the atmosphere—even in extremely dry conditions.  These novel materials could transform the way water is sourced, offering an alternative to reliance on dwindling natural reservoirs.  The development comes at a critical time, as water shortages intensify across the western U.S. and globally. … ”  Read more from Newsweek.

USGS-led study: Shoreline seasonality of California’s beaches

“Most of the world’s beaches exhibit regular cycles of erosion and recovery, but new USGS-led research is showing that these cycles may be considerably different from common perceptions.  One common pattern of beach morphology is the seasonal cycle of the shoreline. Shorelines often show cycles of erosion and recovery year after year, which results in recurring widening and narrowing of the beach.  Scientists know that these cycles are related to ocean waves, and that larger waves cause movement of beach sand offshore whereas smaller waves move this sand back to the beach.  Knowledge of these seasonal cycles comes from a long history of scientific measurement of beaches, and a general consensus is that beaches erode during winter conditions and recover during the summer. These descriptions of winter and summer beach conditions are so well accepted that they can be found in most earth and ocean science textbooks.  However, new research by USGS and partners using large datasets of beaches from satellite imagery shows that this winter/summer framework doesn’t fit all beaches—including the majority of southern California’s beaches. … ”  Read more from the USGS.

Newsom must bring balance back into California’s environmental policy

Edwin A. Lombard III, the executive director of Californians for Smarter Sustainability, writes, ““You can please some of the people all of the time, you can please all of the people some of the time, but you can’t please all of the people all of the time.” Although penned by a poet, it may be more apropos for politics — it was famously co-opted by Abraham Lincoln, after all. In 2025, Governor Gavin Newsom would be well served to take a page from Lincoln’s book when it comes to his own sustainability policies in California.  With less than two years left in his administration, Newsom is in a difficult position as he tries to solve existing challenges while carving out a lasting legacy of environmental stewardship and signature accomplishments. Yet despite his self-proclaimed commitment to the environment, the governor has drawn some criticism from climate groups that oppose several of his much-needed water infrastructure projects. … ”  Read more from the Times of San Diego.

DAN WALTERS: Colorado River poses another California water conflict that Trump will affect

“President Donald Trump’s intrusion into California’s long-running conflict over water management – essentially favoring farmers over wildlife habitat – has drawn massive media and political attention.  Trump ordered federal water managers to release more water for farmers but the increased flows have so far been largely symbolic because farmers use little water during the winter but need more during the growing season.  Trump’s action has been denounced by environmental groups which have long sought to enhance river flows for salmon and other species, with tacit support from Gov. Gavin Newsom’s administration.  However, Newsom directed state water managers to maximize retention of runoff from recent rains to raise water levels in reservoirs, an action that some environmentalists criticized as emulating Trump.  These events represent a continuation not only of California’s internal conflicts over water but pick up where Trump left off during his first stint in the White House. … ”  Read more from Dan Walters at Cal Matters.

At hidden Tahoe lab, scientists learn the art of measuring snow

Anyone riding the gondola lift at Sugar Bowl Ski Resort one bright day in January might have seen something unexpected in the glade below them: A series of figures energetically digging pits in the snow by hand – deep enough for them to then jump inside.  These pit diggers intently studied the walls of their newly carved chambers, before pressing bright yellow sensors into the ice. They were in fact student scientists receiving training from the Central Sierra Snow Lab close by.  And while most visitors to the Sierra would never have a reason to come across this stocky, unassuming 1940s cabin nestled on a nearby backroad, the Snow Lab has been at the forefront of snow science for almost 80 years, maintaining the data that has huge implications for California’s water supply. … ”  Read more from KQED.

Latest precipitation due to atmospheric river adds 12 billion gallons of water to Lake Tahoe

Shasta Dam boosting water releases again as Lake Shasta rises 20 feet in February

“Shasta Dam will increase water releases again to receive more rain from the storms passing through Redding and far Northern California through Friday.  The U.S. Bureau of Reclamation’s move, announced on Thursday, could mean more flooding along the Sacramento River, affecting homes and businesses in parts of Redding and Anderson.  That prompted Shasta Sheriff Michael Johnson to close the Sacramento River to recreational boating below Shasta Dam to the county line starting at 6 p.m. on Friday.  The storms and runoff from hard rains this week boosted Lake Shasta’s water level another 5 feet through Wednesday, according to the California Department of Water Resources. All told, the lake, California’s largest reservoir, has risen about 20 feet so far in February. … ”  Read more from the Redding Record Searchlight.

Keswick Dam increases into Sacramento River to reach 40K cfs

“The Bureau of Reclamation announced Wednesday that the Keswick Dam would release water into the Sacramento River on Thursday and Friday.  The Bureau of Reclamation reported that water released from the dam into the river would increase from 7,500 to 20,000 cubic feet per second on Thursday and then to around 40,000 cfs on Friday. The agency explained that the elevated releases are due to recent storms resulting in inflows into the Shasta Reservoir. It recommended caution along the river.  Tehama County Deputy Public Works Director Justin Jenson said his department uses the California Nevada River Forecast Center to predict river levels. According to Jenson, the center indicates that the river will remain below flood stage through Tuesday next week, and the weather forecast looks favorable for that to remain the case as well.  “One thing landowners can do to reduce localized flooding is to maintain the drainages on their property,” Jenson shared. “If you own property with a creek or draw on it, you are required to maintain it. That means clearing debris and overgrowth. Most hand work in drainages does not require specialized permits.” … ”  Read more from the Chico Enterprise-Record.

C&H ordered to stop dumping raw sugar into Carquinez Strait

“The U.S. Environmental Protection Agency ordered C&H Sugar to cease dumping raw sugar into the Carquinez Strait —  an act that agency officials say violates the Clean Water Act.  The Clean Water Act, enacted in 1948*, regulates discharges of pollutants into U.S. waters.  EPA officials said last month that on at least three occasions, raw sugar was discharged into the strait from ships delivering sugar to the C&H refinery in Crockett. Sugary wastewater can deplete dissolved oxygen when dumped into water, which could endanger fish and other sea life, officials said.  The EPA said the refinery also failed to maintain a proper wastewater system and fully implement its stormwater pollution prevention plan, in addition to violating its discharge limits. … ”  (*Note:  The Clean Water Act was signed into law on October 18, 1972.

Inside the LA fire cleanup’s rush to remove tons of toxic rubble

“Removing toxic waste from the foothills and coastal canyons where more than 16,000 homes and businesses burned down in the Los Angeles wildfires was always going to be an unprecedented challenge in a densely-populated, traffic-choked metropolis. And then the Trump administration ordered the job to be completed in just 30 days.  Federal officials revealed the deadline on Jan. 29, days after President Donald Trump met with survivors of the Pacific Palisades fire. The US Environmental Protection Agency said that it’s been “tasked” with finishing the household hazardous materials cleanup within a month.  But the vast scale of the damage is testing the government’s well-honed wildfire playbook and signals the growing challenge of responding to ever-more frequent and destructive climate disasters. It took the EPA more than three months to remove hazardous debris from 1,448 residential and commercial properties incinerated in the 2023 Lahaina wildfire in Hawaii. LA has nearly 10 times the number of destroyed buildings and at least five times as many potentially explosive electric vehicles abandoned in fire zones that must be disarmed. … ”  Read more from Bloomberg.

Earth doesn’t burn: (back) toward a fire-wise infrastructure in Southern California

Dr. Kenjus D. Watson writes, “In October 2020, as the Bobcat Fire threatened to scale the San Gabriel Mountains and descend into Pasadena, my family and I packed our essentials and temporarily relocated with loved ones across the country in Ohio. The fire wasn’t just a natural disaster; it was a symptom of larger systemic failures. Between the fire, terrible air quality, and the ongoing COVID pandemic, my wife and I felt the acute fragility of our situation as we sheltered in the Midwest with our 7-month-old daughter, who is now 5 years old.  That evacuation marked a turning point for me.

5 approaches that experts say are our best shot at surviving future wildfires

“At their peak, the devastating wildfires that ignited around Los Angeles in January forced upward of 200,000 people to evacuate and torched more than 16,000 homes, offices, and shops. The total economic losses may reach as high as $275 billion. Now the blazes are fully contained and have mostly died down.  As Angelenos grapple with their losses, the disaster has turned into an excuse for some to litigate their grievances with the state: President Donald Trump said that federal aid to California should be conditioned on policy changes like voter ID laws. He also ordered a reservoir that isn’t connected to Southern California’s water supply to dump 2.2 billion gallons of water. There were indeed decisions that did make the fires more destructive than they needed to be. Wildfires are a natural part of the landscape in Southern California, but as more people move into vulnerable areas, the risk of sparking a fire and the scale of the ensuing destruction grow. And as average temperatures rise due to climate change, the Golden State is likely to experience more of the weather sequences that created the fuel for the recent wildfires. … ”  Read more from Vox.
