Marine heatwave ‘blob’ returns in Pacific, rivaling past events in size and impact

“In 2013, scientists noticed a block of unusually warm water detected in the Pacific Ocean between the Gulf of Alaska and the Coast of Southern California. This was recognized by meteorologists as a basin-scale marine heatwave (MHW), often referred to as “the blob”. This water mass hung around from 2013-2016 before re-emerging again in July of 2019 (known as Blob 2.0) and lasting 20 months.  In May 2025, the blob reappeared.  Rachel Hager, a spokesperson for NOAA Fisheries, said this new MHW has grown “approximately the same size as the contiguous U.S.” She added it now ranks among the top three largest MHWs ever recorded in the northeast Pacific Ocean since monitoring began in 1982. … ”  Read more from KATU.

How to make water conservation a habit

“Michael Kimmelman’s recent story on Los Angeles’s water needs included a surprising fact: The city has been using less water, even as its population has grown. Part of this success, Michael reported, came from adopting a culture of conservation after a series of severe droughts, starting in the 1970s, prompted “some simple, practical, boring fixes, like better plumbing, alongside larger transformations in social norms, policies and politics.” In a 2024 survey from the Metropolitan Water District of Southern California, 90 percent of respondents said they considered it important to conserve water daily, even when the region is not in a drought. We asked readers around the country what they thought of Los Angeles’s approach to water conservation, and whether they had taken similar actions. More than 500 wrote in to offer their thoughts. … ” Read more from the New York Times.

Worms now contributing to California’s planet-smart dairy efforts

Worm beds are wiggling their way onto a growing number of California dairy farms. Millions of worms are being deployed to help break down and improve the recycling of manure via these vermifiltration systems. It’s a process that’s gaining traction for its value in preventing methane emissions, better managing nutrients, and improving water use and protection. Essentially, it works like this: dairy manure is added to beds of wood chips and red wiggler worms. The aerobic conditions (inclusion of oxygen) prevents the formation of methane emissions from manure storage by up to 90 percent, according to BioFiltro. The amount of nitrogen in the remaining filtered manure-water is also reduced by 40 to 80 percent. The filtered water is then available for more flexible on-farm use. … ” Read more from Dairy Cares.

California Farm Bureau’s Shannon Douglas tackles Prop 50, Farm Bill, and the future of farming

“The September 26 edition of the AgNet News Hour closed out the week with one of the state’s most important agricultural voices. Hosts Nick Papagni and Josh McGill welcomed Shannon Douglas, president of the California Farm Bureau, for a wide-ranging conversation on water, regulation, trade, and the survival of California’s family farms.  Douglas, a former FFA member and now a proud “FFA mom,” shared her passion for youth in agriculture. She reminded listeners that FFA isn’t just for farm kids — it can spark careers in science, technology, and leadership for students from all backgrounds. “We have tremendous career opportunities in agriculture,” she said, pointing to data showing over four jobs per crop science graduate in California. … ”  Read more from Ag Net West.

Agriculture is tested in courtrooms and at the ballot box

“Throughout September, agriculture has been at the forefront of both legal and legislative battles, with the ultimate winners and losers awaiting a final tally.  Notably, litigation over water and animal welfare has intensified, while local Kern County officials push back against state policies that threaten to undermine California agriculture.  On Sept. 5, the Ninth Circuit Court of Appeals ruled that irrigated agriculture remains exempt from the Clean Water Act. This ruling in “Pacific Coast Federation of Fishermen’s Associations v. Nickels” affirms that irrigation return flows through farm drains do not require federal permits, provided they are not commingled with non-agricultural discharges like industrial or municipal waste. … On Sept. 23, the Eastern Tule Groundwater Sustainability Agency lost two key motions in Tulare County Superior Court in a lawsuit filed by the Friant Water Authority and Arvin-Edison Water Storage District. … ”  Read more from Valley Ag Voice.

Court ruling protects local farm drainage practices

“On September 5, 2025, a decision by the Ninth Circuit Court of Appeals reaffirmed that agricultural drainage systems carrying irrigation return flows can operate without federal Clean Water Act permits, so long as those systems are not mixed with discharges from outside point sources. The ruling is particularly significant for farmers in the Grassland Drainage Area west of Los Banos, where thousands of acres of irrigated farmland rely on engineered drains to carry away subsurface water laden with salts and selenium. For decades, that drainage has been managed through the Grassland Bypass Project, which diverts flows away from wetlands and wildlife refuges before sending them to Mud Slough and the San Joaquin River. … ” Read more from the Los Banos Enterprise.

DWR releases new FAQ on Flood-MAR

“Flood-MAR is a water resource management strategy that uses high flows resulting from, or in anticipation of, rainfall or snowmelt for managed aquifer recharge (MAR). Flood-MAR occurs on agricultural lands, working landscapes, and managed natural lands, including refuges, floodplains, and flood bypasses. Flood-MAR can be implemented at multiple scales, ranging from individual landowners diverting flood water using existing infrastructure, to using extensive detention/recharge areas and modernizing flood management infrastructure/operations. … ”  Read/download the FAQ here.

Natural Resources Agency strengthens Tribal Consultation Policy

“The California Natural Resources Agency (CNRA) has released an updated Tribal Consultation Policy setting clear standards for early, often, and meaningful consultations with tribes in agency actions. The revised policy formalizes CNRA’s commitment to building lasting partnerships with California Native American tribes and addressing historic wrongs that excluded tribes from the stewardship of their ancestral lands and waters.  For decades, state policies disrupted tribal stewardship and excluded tribes from key decisions. The updated Tribal Consultation Policy aims to correct this by providing a policy framework for all CNRA departments, conservancies, commissions, and boards. It clarifies the role of tribal liaisons, outlines mandatory training requirements, and includes a Tribal Consultation Best Practices Appendix with proven consultation models to guide staff.  “California is stronger when we work in true partnership with tribes,” said CNRA Secretary Wade Crowfoot. “This policy moves us beyond symbolic commitments and into action by setting clear standards for consultation. By listening early, engaging often and respecting tribal leadership, we will build more trust and create better outcomes for people and nature.” … ”  Read more from the Natural Resources Agency.

Whales are getting tangled in lines and ropes off the California coast in record numbers

“The number of whales getting tangled up in fishing nets, line, buoys and other miscellaneous rope off the coasts of the United States hit a record high in 2024, with California taking the ignominious lead. According to the National Oceanographic and Atmospheric Administration, there were 95 confirmed entangled whales in U.S. waters last year. Eighty-seven were live animals, while reports for eight came in after the animals had died. On average, 71 whales are reported entangled each year. There were 64 in 2023. More than 70% of the reports were from the coastal waters off California, Alaska, Hawaii and Massachusetts. California accounted for 25% in 2024, most in the San Francisco and Monterey bay areas. … ” Read more from the LA Times.

Unburned: An Investigation:  To protect the Plumas National Forest and its communities from the next megafire, the Forest Service plans to burn it—intentionally. Can $274 million do the job?

“A white-headed woodpecker stirs the dawn quiet, hammering at a patch of charred bark stretching 15 feet up the trunk of a ponderosa pine. The first streaks of sun light the tree’s green crown, sending beams across this grove of healthy conifers. The marks of the 2021 Dixie Fire are everywhere. Several blackened trees lie toppled among the pale blossoms of deer brush and the spikes of snow plants, their crimson faded to dusky coral.  Flames raged through neighboring forests, exploding the tops of trees, flinging sparks down the mountainside until, on August 4, 2021, the fire itself reached the valley below and Greenville, 90 miles north of Lake Oroville. It took less than 30 minutes to destroy a town of 1,000 residents. Yet this stand at Round Valley Reservoir survived.   Years earlier, U.S. Forest Service crews had removed the brush and smaller trees, reducing the most flammable vegetation. Then they set fires, burning what was left on the ground in slow-moving spurts of flame. When Dixie arrived, the same fire that melted cars and torched 800 homes hit this stand and dropped to the ground. Here Dixie was tame, a docile blaze meandering across the forest floor with only occasional licks up the trunks of trees, says Ryan Bauer, Plumas National Forest fuels manager for the past 18 years.  If only there had been more active forest management like this, laments Bauer. … ”  Read more from Bay Nature.

Autumn’s arrival brings sharp transitions to Bay Area weekend weather, significant storm to follow

“The first official weekend of autumn arrives and each day will feel a little different, thanks to a stubborn upper-level low pressure system drifting across the state.  This weekend won’t bring the kind of steady, predictable weather pattern California is known for. Instead, the weather will swing in noticeable ways, in the Bay Area and statewide.  Friday will be warm, with North Bay and East Bay valleys reaching into the 90s. But unlike Tuesday’s widespread heat, the coast and bayside communities will stay cooler, with San Francisco and Oakland holding in the 70s under a stronger sea breeze and marine layer.  Saturday eases down another notch. Sunshine will dominate, but the 90s disappear, with most inland highs topping out in the 80s. San Francisco and Oakland stay in the 70s, slower to clear morning clouds.  By Sunday, the seasonal change will be hard to miss. … ”  Read more from the San Francisco Chronicle.

Modeling flood mitigation strategies in the San Francisco Bay Area

Extreme 2-year water levels in SF Bay under baseline; restoration; urban; and combined scenarios at current versus 1.5 m SLR.

“As sea levels rise and storms intensify, protecting coastal communities is becoming a pressing challenge—especially in places like San Francisco Bay, one of the nation’s most urbanized estuaries. A new USGS-led study explores how different flood-mitigation strategies—shoreline hardening, wetland restoration, and floodgates—affect water levels across the Bay.  Using a high-resolution Delft3D hydrodynamic model for the San Francisco Bay-Delta community, the researchers tested how each mitigation strategy would perform under both current conditions and future sea-level rise scenarios. The results found trade-offs and limitations for each approach … ”  Read more from the USGS.

Stockton breaks ground on $17 million Groundwater Recharge Project

“San Joaquin County and Stockton officials and project executives broke ground on the $17 million project-site Wednesday morning on the Groundwater Recharge Project. The project will build three recharge basins adjacent to the treatment plant, allowing the city to capture water from the San Joaquin Delta and Mokelumne River. It’s phase two of the plant’s expansion – the facility itself, opened in 2012, already treats up to 30 million gallons a day for nearly 200,000 customers. Stockton Mayor Christina Fugazi explained how the project would become crucial during a dry season with little rain. “This groundbreaking is very significant because it has to do with groundwater recharge,” Fugazi said. “When we’re experiencing a drought, we’re limited in where we can pull our water from. When our groundwater has been recharged, we’re able to pull from there.” … ” Read more from Stocktonia.

With reservoirs shrinking, Southern California braces for hard choices on most precious resource

“As climate change drives drier winters and shrinking snowmelt across the West, Southern California is rushing to diversify its water supply—investing in recycling, storage, and Colorado River imports to guard against another crippling drought. With fire season approaching, public officials are debating not only whether Southern California has enough water to battle potential blazes like the one in Pacific Palisades, but also whether supplies will be sufficient in the coming months and years to meet basic drinking needs. SoCal’s tenuous access to water is tethered to the California Aqueduct in the north, which provides most of the water for the local communities served by the Las Virgenes and Calleguas municipal water districts, and to the Colorado River Aqueduct in the east, which looms large as a possible new source for potable supply serving the local communities. … ” Read more from The Acorn.

Experts warn action needed to preserve Colorado River

“The Colorado River has been in decline since the turn of the 21st century – and emergency action may be required sooner than projected, experts warn. They say realistic water storage, accounting for less than half of typical Colorado River reservoir projections, could be drained within a few years if the issue is not taken seriously. “Unfortunately, if this coming winter is as bad as this past winter, we’re going to be dealing with a significant problem,” Dr. Jack Schmidt, director of the Center for Colorado River Studies at Utah State University, told The Center Square.

Commentary: Feds need a different approach to the Colorado River

Greg Walcher, president of the Natural Resources Group and author of “Smoking Them Out: The Theft of the Environment and How to Take it Back,” writes, “This week’s withdrawal of President Trump’s nominee to head the Bureau of Reclamation (BOR) provides an opportunity, not just for a new nominee but for a new approach to the whole Colorado River management mess. It is an opportunity the White House and Interior Secretary Doug Burgum should take very seriously.  The nominee’s withdrawal, due to the skepticism of Upper Basin senators, highlighted the deteriorating relationship between BOR and the states.  In fact, BOR under Trump has thus far taken essentially the same tack as under Presidents Obama and Biden, namely threatening the states — including those in the Upper Basin — with a federal takeover if they don’t produce an “acceptable” plan to reduce their use of water. As negotiations between the seven Colorado River states have ground almost to a standstill, they are being reminded of a November “deadline” to submit a “preliminary assessment” of their ability to reach consensus. If the states notify BOR by Nov. 11 that a consensus agreement is unlikely, the agency says it will develop a federal plan for river management. … ”  Read more from the Daily Sentinel.

Commentary: Efficiency, not water wars, can save the Colorado River

Jason Shulman, a Colorado resident and owner of Colorado CareAssist, writes, “I write as a resident of Colorado, where every drop of the river matters to our farms, families, and future. I have no fiduciary interest in water. I don’t own land around it, nor any water rights attached to it. But, simply put, I like to drink water to survive so its supply in the very dry American West has always interested me. Particularly the Colorado River and the millions of us who depend on it. The Colorado River is the lifeline of the American West, but it is dangerously over‑appropriated. Agriculture consumes the majority of its flow, and nowhere is this more concentrated than in the Imperial Irrigation District (IID) in California and Yuma. These regions supply most of America’s winter vegetables — but they also devote massive acreage to alfalfa hay, much of it exported overseas, using about six acre‑feet of water per acre each year. That fact often leads people to frame the problem as “food vs. alfalfa.” But I believe we can solve this without starving our nation of food. The answer is targeted efficiency — rewarding real, measured conservation and shifting crop mixes where it makes sense. … ” Read more from the Arizona Capitol Times.

Queen Creek looking to gain water independence with groundwater from Harquahala Valley

“The town of Queen Creek is among the only communities in the Phoenix metro region that is not considered a designated water provider. That means that its residents have to pay a fee to get water delivered and to replenish groundwater they use.  This month, the Queen Creek Town Council authorized officials to negotiate a potential $240 million deal to pump groundwater from Harquahala Valley, about 70 miles west of Phoenix. That additional groundwater would help Queen Creek qualify as designated water providers.  “By becoming designated, we will no longer be pumping groundwater that needs to be replenished,” said Queen Creek Water Resource Director Paul Gardner.  The deal would be for up to 1.2 million acre feet of water over the next 100 years, though the final agreement could come out to half that amount. … ”  Read more from KJZZ.

Some US streams and rivers facing severe declines in fish populations, new study suggests

“The composition of fish populations in streams and rivers across the U.S. has been severely altered as a result of changing water temperatures and human-driven introductions of fish, according to new research. Cold-water streams have experienced disproportionate impacts, experiencing more than a 50% decrease in fish abundance over the last three decades, according to a study published Wednesday in Nature. Some of the largest threats include climate change and fish introductions — both by invasive species or game fish stocking, scientists say. Researchers from the U.S. Environmental Protection Agency tracked trends in freshwater fish biodiversity in streams and rivers all over the U.S. from 1993 to 2019. During that time, they monitored 389 species across 2,992 sites. They found that species abundance, or the number of individual fish, and species richness, the number of unique species, declined by 53.4% and 32%, respectively, in cold streams — where temperatures are typically below 60 degrees Fahrenheit. … ” Read more from ABC News.

DOE climate report could create problems for EPA

“Science played only a bit part in EPA’s July proposal to scrap the scientific basis for most of its climate rules.  In the final version, it may barely make an appearance.  The draft rule to undo the endangerment finding leaned heavily on a new legal reading of the Clean Air Act asserting that EPA has no authority to regulate greenhouse gases for their effect on climate change. But EPA also floated an “alternative” rationale — one focused on science and drawn almost exclusively from a Department of Energy report that downplayed the risks and severity of climate change.  That report is now in limbo after DOE disbanded the so-called Climate Working Group that wrote it. The agency has come under fire — and a lawsuit — for the process that led to the establishment of the working group, which was staffed with five climate contrarians hand-picked by Energy Secretary Chris Wright. … ”  Read more from E&E News.

Human impacts on ocean could double or triple by 2050, a new UC Santa Barbara study warns
