Surprise atmospheric rivers, toxic seafood: How NOAA cuts could impact California

“Coast Guard rescue missions failing after running into unexpected currents. Surprise atmospheric river storms flooding downtown San Francisco. Seafood contaminated by unseen algal blooms. California scientists fear these scenarios, and more, are possible under the Trump administration’s recommendation to reduce the National Oceanic and Atmospheric Administration’s budget by $1.7 billion.  Several scientific programs in California are slated for significant reductions or elimination if the budget proposal is pushed through Congress. Scientists say the cuts would hamper weather forecasting, disrupt critical ocean data collection and decimate climate research.  One of the programs at risk is the Central and Northern California Ocean Observing System. The association receives roughly $3.3 million annually from NOAA to manage instruments that monitor winds, water levels, ocean currents, heat and other data critical for business, forecasts and safety. … ”  Read more from the San Francisco Chronicle (gift article).

NASA tracks snowmelt to improve water management


The C-20A aircraft, based at NASA’s Armstrong Flight Research Center in Edwards, California, flies over the Sierra Nevada Mountains in California for the Dense UAVSAR Snow Time (DUST) mission on Feb. 28, 2025. The DUST mission collected airborne data about snow water to help improve water management and reservoir systems on the ground. NASA/Starr Ginn

“As part of a science mission tracking one of Earth’s most precious resources – water – NASA’s C-20A aircraft conducted a series of seven research flights in March that can help researchers track the process and timeline as snow melts and transforms into a freshwater resource. The agency’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) installed on the aircraft collected measurements of seasonal snow cover and estimate the freshwater contained in it.  “Seasonal snow is a critical resource for drinking water, power generation, supporting multi-billion dollar agricultural and recreation industries,” said Starr Ginn, C-20A project manager at NASA’s Armstrong Flight Research Center in Edwards, California.  “Consequently, understanding the distribution of seasonal snow storage and subsequent runoff is essential.”  The Dense UAVSAR Snow Time (DUST) mission mapped snow accumulation over the Sierra Nevada mountains in California and the Rocky Mountains in Idaho. Mission scientists can use these observations to estimate the amount of water stored in that snow. … ”  Read more from NASA.

This weekend’s California storm looks different. Here’s why

“A slow spring storm is headed for California this weekend, but it’s missing one key ingredient that typically drives the state’s most intense weather events: the jet stream.  Instead, this weekend’s storm system is the atmospheric equivalent of a boat adrift at sea. Meteorologists refer to this as a cutoff low, which is essentially a pool of cold air accompanied by a low pressure center that’s broken away from the main flow of the jet stream.  Without the strong upper-level winds to steer it, the storm will drift south along the California coast and linger into the weekend, stirring up light rain, isolated thunderstorms and even some late-season mountain snow in the Sierra. But unlike a classic winter storm, this one won’t bring much organized or widespread precipitation. … ”  Read more from the San Francisco Chronicle.

New analysis shows Sites Reservoir’s water-capturing potential

Proposed location of Sites Reservoir

“The Sites Project Authority revealed that the Sites Reservoir could have captured more than 550,000 acre-feet of water from late November 2024 through early April 2025.  According to officials, this amount of water capture could have benefited more than three million people.  Fritz Durst, Chair of the Sites Project Authority Board of Directors, emphasized the reservoir’s potential. “Once again, we’re seeing how well Sites Reservoir would perform during wet periods if it were operational today, by capturing and storing water for drier periods,” Durst said. … ”  Read more from Action News Now.

Officials recommend Salmon fishing in California for the first time in years

“Lining up for a boat inspection, lifelong fisherman Mike Popovich recalls fond memories of salmon fishing in California — especially a particular day on the Klamath.  “Klamath River, the mouth,” Popovich said. “Just, maybe 20 years ago, incredible. Just as fast as you could cast out, you catch fish. It was amazing. My sons were catching 30 pound salmon.”  Popovich, like many others, hasn’t been able to fish for Pacific Chinook Salmon for three years, amid continuing bans in state oceans and rivers from declining populations, because of climate change, water management and habitat loss. … ”  Read more from Spectrum 1.

DWR partners with communities on turf replacement projects to improve local climate resilience

“To celebrate Earth Week, the Department of Water Resources (DWR) is rolling out a new program to work with local communities on multiple turf and landscape replacement projects that will save water and help combat against future droughts and climate change. What makes this innovative partnership unique is the focus on replacing turf at businesses and institutions rather than solely residential sites.  In collaboration with Watershed Progressive, DWR’s Turf Replacement Pilot Program provides direct assistance to replace ornamental turf with drought-tolerant and water-efficient landscaping in California’s frontline communities. Supported by the Budget Act of 2021, the program is investing $35 million in communities that are on the frontlines of climate change, lack reliable water supplies, and need support with restoring natural environments. The program will provide hands-on support with lawn removal and direct installation of water-wise alternatives for residential, commercial, and institutional landscapes at no additional cost. … ”  Read more from DWR News.

How (and when) can you get your hands on California’s climate bond?

““I think this is breaking my Teams right now,” said Evyan Borgnis Sloane, deputy executive officer for the California State Coastal Conservancy. She was starting a webinar, and some 600 people had flooded the online waiting room—an unusual crowd for a standard agency webinar on funding processes.  It spoke to how thirsty people have been for information on Proposition 4’s $10 billion bond, approved by California voters in November 2024, to fund climate adaptation work across the state. During the campaign, proponents touted it as a critical down payment to offset the worst (and accelerating) state-wide costs of climate change. But as Trump has cut or threatened federal climate funding, “everyone is hoping to get Prop 4 money,” says Robert Mazurek, the executive director of the California Marine Sanctuaries Foundation. … ”  Read more from Bay Nature.

Central Valley farmers need a fighting chance to survive. This bill will help

Robin Singh, of Madera and owner Singh Farms, writes, “I’ve owned farmland and grown almonds here in Fresno County for nearly two decades, including for the last eight years in Cantua Ranch, a beautiful stretch of land that has been the backbone of my operation and my family’s livelihood. But now, the land I’ve poured years of labor and love into is at risk – not because we lack the knowledge, equipment, or will to farm it, but because these fields are drying up. That’s the reality for growers like me across the Central Valley. In 2014 California passed the Sustainable Groundwater Management Act (SGMA), a well-intentioned law to protect California’s water future. I support the need for sustainable water use. But as SGMA implementation rolls out, farmers like me are being told we may have to drastically cut back groundwater pumping, so much so that we might only be able to farm a fraction of our land. In my case, projections suggest I could be limited to putting just one-sixth of my land into permanent crops. … ”  Read more from the Fresno Bee.

The California ESA and habitat protection

Eric Biber, a specialist in conservation biology, land-use planning and public lands law, writes, “Following up on my prior post about the proposed changes to the federal Endangered Species Act (ESA) regulations that protect against habitat modification, what might California do to protect the species within its border?  California currently has 140 federally listed animal species, and 182 federally listed plant species, 19% of the 1684 species listed under the ESA in the United States.  California also has its own endangered species law, the California Endangered Species Act (CESA), which provides substantial protections for listed species independent of the federal ESA.  Thus, California can provide an important backstop for protection of endangered species within its borders, regardless of what happens under the federal ESA, and because of the number of listed species in California, California’s efforts would make a significant impact in protecting biodiversity. … ”  Read more from the Legal Planet.

Commentary: Understanding ‘full allocation’ for Klamath farmers

Gene Souza, Klamath Irrigation District, writes, “The term “full allocation” is central to discussions about water rights for farmers on and off the Klamath Reclamation Project, but its meaning is often misunderstood. For the more than 220,000 acres of farmland in the Klamath Reclamation Project, a “full allocation” of water is not a single number but a range of measurements tied to contracts, legal adjudications, and the practical needs of crops. As poor federal policy continues to strain the region’s water resources, clarity on this term is essential for informed, on-farm decision-making. According to some contracts, such as the 1905 contract entered into by the Klamath Irrigation District, and for Tule Lake Irrigation District, which cover more than 100,000 acres within their borders, a “full allocation” is defined as water sufficient for beneficial use without waste. That number is unknowable …but able to be roughly estimated as exceeding 300,000 acre-feet for these two districts in an average year. … ”  Continue reading at the Herald & News.

CalTrout acquires key Elk River land parcels, returns historic site to Wiyot Tribe for cultural restoration

CalTrout, in partnership with the State Coastal Conservancy (SCC), announced today the acquisition of four key parcels of former ranch land (175 acres) along the Elk River in Humboldt County, marking a significant step in the ongoing efforts to protect and restore the Elk River estuary. Three of these parcels will eventually be transferred to the California Department of Fish and Wildlife’s (CDFW) existing Elk River Wildlife Area (ERWA) for continued stewardship and ecological restoration, while the fourth parcel, of special cultural importance to the Wiyot Tribe, was returned to the Tribe for its ancestral ownership.  The Elk River, the largest tributary to Humboldt Bay, supports sustainable local agriculture, is a hub for essential fish habitat, and flows through several residential communities. However, years of intensive land uses for timber harvest and agriculture have caused significant changes across the landscape, shifting the balance away from functional ecosystems and native fish populations. … ”  Read more from CalTrout.

New study of Lake Mendocino water storage launched

“A group of officials who are keenly interested in the amount of water stored in Lake Mendocino met in Ukiah recently to celebrate the launch of another study that could eventually lead to increasing the storage capacity of the reservoir.  “Inaccurate storage in this reservoir is actually a threat to people and wildlife and our economy,” said Rep. Jared Huffman (D – San Rafael), who secured $500,000 last year for the latest feasibility study, officially called the Coyote Valley Dam General Investigation Study, while speaking April 11 near the dam. “And those threats are going to be exacerbated, potentially, by uncertainties with Pacific Gas and Electric’s removal of the antiquated Potter Valley Project system, but there’s also an opportunity here: if we work together, doing some of the things we need to do with the Two-Basin Solution, and then raising this dam that we’re standing on, which can make that Two-Basin Solution so much more effective, and so much more reliable.” … ”  Read more from the Mendocino Beacon.

A unique San Francisco Bay marine lab faces closure. It has days to raise millions.

“Ecologist Katharyn Boyer must shutter the beloved marine research center she manages on the San Francisco Bay’s shores — unless she can raise millions of dollars by next week. Scientists, conservationists and community members statewide have rallied to save the Estuary and Ocean Science Center since San Francisco State University announced earlier this year that it could no longer afford to keep the doors open on its 53-acre Tiburon campus. University representatives told KQED this week that $10 million would allow them to keep the lab open at least in the short term. Boyer, the center’s interim executive director, is still scrambling to convince donors to pledge the money before the start of May. Otherwise, San Francisco State will start phasing out the center’s operations over the next six months. “It’s very little time and a lot of money, and I am starting to lose hope,” Boyer said. “There are some folks that are interested in supporting us. Whether that can happen fast enough is a really big question.” … ”  Read more from KQED.

SAN DIEGO

San Diego County water rate hikes won’t be as painful as feared

“Wholesale water rates — a key driver of the water bills of residents and businesses across the county — are not expected to rise nearly as much next year as previously thought.  County water officials on Thursday lowered their projected wholesale water rate hike for next year from 18% to 12%, thanks primarily to higher projected water sales to local agencies over the next three years.  The higher sales projections are based partly on the particularly dry winter and spring San Diego has experienced, which has increased demand for irrigation water from farmers and people with large lawns.  Higher sales help the finances of the water authority because it is contractually obligated to buy more water than its member agencies typically need, forcing it to raise rates to cover its built-in costs.  But the dry winter has pushed the expected demand from member agencies for next year about 10% higher than was estimated just last month — from 300,000 acre-feet to 327,000 acre-feet. … ”  Read more from the San Diego Union-Tribune.

NOAA collaboration provides backbone for global environmental intelligence

“Since late February, many hundreds of California sea lions, dolphins, whales, and seabirds have stranded themselves along Southern California coastlines. The sea lions appear dazed, listless, and sometimes acting erratically. The diagnosis — domoic acid poisoning — is caused by a neurotoxin produced by a commonly found marine plankton in coastal waters. Domoic acid can cause illness and death in marine mammals, and be dangerous or fatal to humans if they consume contaminated seafood.  This event, still underway three months later, marks the fourth consecutive year that a toxic algae bloom has caused marine mammal and seabird mortality events in Southern California. These blooms, which cost the U.S. economy $50 million each year through damage to public health, fisheries, and coastal recreation, are tracked in a myriad of ways, with the support of the National Oceanic and Atmospheric Administration (NOAA), a federal agency currently impacted by federal staffing cuts and threats to long-term funding. … ”  Read more from Scripps Institution of Oceanography.

Dust is speeding up snowmelt in the Colorado River, University of Utah study finds

“Researchers at the University of Utah recently published a first-of-its-kind study that measures the impact dust has on melting snow in the Colorado River basin.  Dust has long been credited to accelerating snowmelt in the Intermountain West. Blowing from arid regions and settling in the mountains, the dust darkens the snow, lowering its albedo — essentially, darker snow doesn’t reflect the sunlight as well, leading to more heat absorption and speeding up the melting process.  It’s particularly prevalent in the Colorado River basin, with large mountain ranges like the San Juans, La Sals and Maroon Bells pushed up against dry expanses of desert. As drought continues to impact the region, dust events have worsened, depleting the snowpack at faster rates and complicating an already precarious situation for the Colorado River and the 40 million people who get their drinking water from it. … ”  Read more from Utah News Dispatch.

Every drop counts: Navigating water challenges in manufacturing and data centers

“On April 10th, Cleantech Group hosted the panel “Every Drop Counts: Navigating Water Challenges in Manufacturing and Data Centers,” in Palo Alto, California. Sponsored by Wilson Sonsini Goodrich & Rosati, the panel featured Chris Spain of HydroPoint, David C. Thompson of ChemTreat, and Jim Oliver of Black & Veatch.  Data centers were the focal point of the conversation. As OpenAI, Facebook, and Google require millions of gallons of water to cool their data centers, municipalities are running extreme risk of devastating water supplies for residents and commercial businesses alike. Data centers currently draw water from 90% of U.S. watersheds, increasing their total withdraws by 35% since 2018. Cities, states, and countries across the globe are committing to this unprecedented water use without clear foresight on what the consequences will be. Every Drop Counts was organized to help identify some pathways forward through this uncertainty.  Each speaker touched on the realities of resource constraints, public engagement, waste management, and partnerships as the key pillars on which successful data center projects are built.
