Water Supply Strategy update: Adapting to a changing climate

“Climate change is rewriting the rules of our environment, and California is feeling the heat—literally. With temperatures climbing to record-breaking levels both statewide and globally, the impacts are impossible to ignore. At the tail end of the 2020-2022 drought, the Department of Water Resources projected that by 2040, California’s water supply could shrink by 10% due to a thirstier atmosphere, parched landscapes, and a phenomenon known as the “evaporative gap,” where rising temperatures accelerate water loss through evaporation, leaving less to sustain ecosystems, agriculture, and communities.  In 2022, the Newsom Administration released the Water Supply Strategy, which focuses on ways to increase water supply and adapt to the more extreme weather patterns caused by climate change.  At the June California Water Commission meeting, Anthony Navasero, Drought Coordinator for the Department of Water Resources, and Annalisa Kihara, Assistant Deputy Director of Division of Water Quality at the State Water Board, shared updates on implementing the Water Supply Strategy, highlighting progress in brackish and seawater desalination, advancing groundwater recharge projects, and improving information systems like stream gauges and a new water rights system. …” Continue reading at Maven’s Notebook.

Scientific surveys show continued decline in white sturgeon population

“Recent results from white sturgeon monitoring surveys by the California Department of Fish and Wildlife (CDFW) suggest the white sturgeon (Acipenser transmontanus) population has continued to decline. CDFW fisheries biologists now estimate there are approximately 6,500 white sturgeon between 40-60 inches long in California — down sharply from the previous estimate of approximately 30,000 fish in that size range, based on the 2016-2021 survey average.  There may be many reasons for the downward trend, including mortality from harmful algal blooms, poaching, past sport fishing harvest and poor river and Delta conditions.  In 2024, CDFW implemented a new method for surveying the white sturgeon population in collaboration with the Pacific States Marine Fisheries Commission and local sturgeon fishing guides. Surveys take place in the spring and fall from San Pablo Bay to Rio Vista and surrounding areas. The methods are based off white sturgeon surveys conducted in Oregon and Washington and modified for use in California. The study design has been peer-reviewed and is the most robust and comprehensive white sturgeon population monitoring survey ever conducted in California. … ”  Continue reading from the Department of Fish & Wildlife.

A nuanced model of soil moisture illuminates plant behavior and climate patterns

“Any home gardener knows they have to tailor their watering regime for different plants. Forgetting to water their flowerbed over the weekend could spell disaster, but the trees will likely be fine. Plants have evolved different strategies to manage their water use, but soil moisture models have mostly neglected this until now.  Researchers at UC Santa Barbara and San Diego State University sought a way to move beyond simple on/off models to capture the nuanced ways that plants manage water stress. To this end, they developed a nonlinear model that can observe these behaviors in satellite data. Their methodology, published in Geophysical Research Letters, will improve climate models and inform our own water management strategies.  “We found that plants don’t respond to water stress in a simple, straight-line way,” said senior author Kelly Caylor, a professor at UCSB’s Bren School of Environmental Science & Management. “Instead, they have dynamic response patterns that reveal whether they’re ‘water spenders’ or ‘water savers.’” … ”  Read more from The Current.

Cracking the Rumors: California Almond Board is busting the myth that the crop requires too much water

“Almond growers are looking to bust an age-old myth that the nut requires too much water.  Clarice Turner, the President and CEO of California’s Almond Board says rumors start out harmless but hurt family farms.  “And that’s the sad part, is that it’s the family farms that are multi-generational who are negatively impacted by this kind of stuff, and I’m pretty sure that the end consumer doesn’t understand that. We’re trying to set the record straight on many, many things, and also continuing to try to help our farmers prosper in the state.” … ”  Read more or watch video from RFD-TV.

Warnings ignored: The grim connection between the L.A. wildfires and Texas floods

“Two major climate disasters of 2025 — the Texas flooding that killed more than 100 people and the L.A. wildfires in January that resulted in 30 deaths and wiped out more than 15,000 homes and businesses — highlight the struggles officials face in fully preparing for extreme weather conditions.  In both cases, the National Weather Service offered clear warnings of potentially life-threatening weather events; in Los Angeles, warnings were given days before extraordinary winds — of up to 100 mph — slammed a region already suffering from a record-dry fall. Even in Texas, more than a day before catastrophic flooding hit Kerr County, state officials — on July 2 — reiterated the weather service’s warnings that “heavy rainfall with the potential to cause flash flooding is anticipated across West Texas and the Hill Country” through the Fourth of July weekend.  But for a variety of reasons, those warnings did not filter down with maximum urgency to various local agencies. … ‘  Read more from the LA Times.

California has an idea to counter Trump’s megabill: Roll back environmental laws

“California lawmakers reeling from President Donald Trump’s assault on clean energy are considering a controversial strategy to keep projects on track — slashing environmental permitting further.  That plan could intensify a fight between clean energy advocates and environmentalists over the trade-offs between building fast and environmental protection that’s already playing out at home.  California officials are scrambling to respond to congressional Republicans’ budget “megabill,” signed into law Friday, which demolishes Biden-era tax credits that incentivize construction of large-scale solar and wind projects, home energy efficiency improvements and electric vehicle purchasing — centerpieces of blue states’ strategies to wean themselves off fossil fuels. … ”  Read more from Politico.

Is California’s water infrastructure ready for climate whiplash?

Edward Ring, Director of Water and Energy Policy at the California Policy Center, writes, “If there is anything that might constitute an overwhelming institutional consensus in California, it’s that we are experiencing climate change, and that one of the consequences will be more rain, less snow, and more so-called whiplash between very wet years and very dry years.  In an average year these days, 30 million acre feet of water flows through the Sacramento-San Joaquin Delta. But nearly half of that water comes down in the form of a melting Sierra snowpack which in an average year holds 15 million acre feet of water. This snowmelt fills the reservoirs and feeds the rivers from April through June. With climate change, so we’re told, the volume of runoff won’t change. But we’ll get almost all of it in the three months of winter. Do we have a system to handle winter flows into the delta that are twice today’s volume?  And if not, for the vast majority who view this scenario as a certainty, why aren’t we building anything? … ”  Continue reading this commentary.

Young indigenous kayakers about to complete historic river journey, after ‘largest dam removal in US history’

“Ruby Williams’ birthday was not your average 18th. She celebrated it on the Klamath River, with a group of young people making a historic journey paddling from the river’s headwaters in southern Oregon to its mouth in the Pacific Ocean, just south of Crescent City, California. It marked the first time in a century that the descent has been possible, after the recent removal of four dams allowed the river to flow freely.  Williams, together with fellow paddler Keeya Wiki, 17, spoke to CNN on day 15 of their month-long journey, which they are due to complete on Friday. At this point, they had just 141 miles (227 kilometers) of the 310-mile (499 kilometer) journey left to go and had already passed through some of the most challenging rapids, such as those at the “Big Bend” and “Hell’s Corner” sections of the river. … ”  Read more from CNN.

Major fine for spill that sent 85,000 gallons of sewage into Lake Tahoe

“Caltrans and the North Tahoe Public Utility District agreed to pay an $850,000 settlement after 85,000 gallons of raw sewage gushed into Lake Tahoe last summer.  In the aftermath of the sewage spill that began the night of July 18, 2024, the Lahontan Regional Water Quality Control Board conducted an investigation and confirmed that the spill was caused by a subcontractor, hired by Caltrans, who punctured a sewer main near Highway 28 in Carnelian Bay.  Caltrans was installing a crosswalk with a flashing beacon on Highway 28. A crew was working a night shift when the worker drilled through the sewer pipeline, which runs underneath Highway 28, from Kings Beach to Dollar Hill.  Untreated sewage leaked out of the ruptured main, spilled across the highway and pooled in a parking lot at Carnelian West Beach, adjacent to Gar Woods Grill & Pier, a popular restaurant in North Lake Tahoe, while guests were still eating dinner. … ”  Read more from SF Gate.

“Troy Delany stood near the shore of Lake Shasta on Tuesday, surrounded by nearly 1.2 trillion gallons of water.  But the enormous amount of water being stored in California’s largest reservoir wasn’t the first thing on his mind. With the lake gently lapping at his ankles, the fact that 2025 marked the third year in a row that rainfall has filled the lake to above-average capacity also didn’t rate high on his list of important matters.  He was focused on things he could see and feel. He had two decent-sized bass on his stringer and on the opposite shore, some 100 yards away, he watched a deer warily amble down to the water’s edge for a sip, her ears twitching at the slightest sound.  While Delany appreciated the good fishing and the serenity of the lake spread out before him, business owners around the lake said they were reaping the tourism benefits that a full lake brings. … ”  Read more from the Redding Record-Searchlight.

Metropolitan advances project to help Southern California communities vulnerable in state droughts

“Construction will soon begin on a project to bring additional sources of water to Southern California communities hit particularly hard by the state’s last drought, following a vote by Metropolitan’s board of directors this week.  The board voted Tuesday (July 8) to authorize an additional $54 million to complete design and begin construction of the Sepulveda Feeder Pump Stations Project, which will push Colorado River water and stored supplies from Diamond Valley Lake – Southern California’s largest reservoir – into communities that currently have limited access to these resources. These communities rely almost exclusively on water from the northern Sierra, delivered through the State Water Project.  “Two years ago, when State Water Project deliveries were severely curtailed because of the record-breaking drought stressing our state, these communities – home to nearly 7 million people – did not have the water they needed to meet demands. Residents and businesses were required to dramatically reduce their water use. In response, our board committed to take immediate action to avoid such water supply shortages in the future,” Metropolitan board Chair Adán Ortega, Jr. said. “Through yesterday’s vote, we are fulfilling that commitment, moving quickly to address this problem.” … ”  Read more from the Metropolitan Water District.

‘Misinformation and misrepresentations’: Palisades Fire victims lob new claims against L.A., state agencies

Poisoned pelicans fly again after the worst algal bloom in a decade

“A flock of brown pelicans waddled back into the wild on Wednesday morning, survivors of Southern California’s latest toxic algal bloom. This year’s bloom was the deadliest such event since 2015, when thousands of animals were killed along a coastal swath stretching from Central California to Alaska.  This year’s intense bloom, which started in January, poisoned the 13 pelicans and many other sea animals in the region, including sea lions that sometimes threatened beachgoers. The pelicans that took off Wednesday had made a full recovery at the Wetlands and Wildlife Care Center in Huntington Beach.  The release was held just south of the pier, with community members invited to watch. “This is always a special moment — not just for our team and volunteers who worked tirelessly to save these birds, but for the community as well,” said Debbie McGuire, executive director of the wildlife nonprofit. “Watching them take flight is a powerful reminder of why our work matters.” … ”  Read more from the LA Times.

Climate change and aerosol pollution made drought inevitable in the US Southwest: Study

“The combined effects of climate change and air pollution have led to direct declines in precipitation in the U.S. Southwest, making drought inevitable, a new study has shown.  These circumstances, which began taking hold in about 1980, are likely here to stay as the planet warms, according to the study, published on Wednesday in Nature Geoscience.  Its authors attributed this decades-long trend toward less precipitation to La Niña-like conditions, weather patterns that lead to cooler surface temperatures in the tropical Pacific Ocean.  Even if El Niño-like conditions had prevailed instead, the Southwest would not have experienced a corresponding surge in rainfall, the researchers found. … ”  Read more from The Hill.

In the sweltering Southwest, planting solar panels in farmland can help both photovoltaics and crops

““We were getting basil leaves the size of your palm,” University of Arizona researcher Greg Barron-Gafford said, describing some of the benefits he and his team have seen farming under solar panels in the Tucson desert.  For 12 years, Barron-Gafford has been investigating agrivoltaics, the integration of solar arrays into working farmland. This practice involves growing crops or other vegetation, such as pollinator-friendly plants, under solar panels, and sometimes grazing livestock in this greenery. Though a relatively new concept, at least 604 agrivoltaic sites have popped up across the United States, according to OpenEI.  Researchers like Barron-Gafford think that, in addition to generating carbon-free electricity, agrivoltaics could offer a ray of hope for agriculture in an increasingly hotter and drier Southwest, as the shade created by these systems has been found to decrease irrigation needs and eliminate heat stress on crops. Plus, the cooling effects of growing plants under solar arrays can actually make the panels work better.  But challenges remain, including some farmers’ attitudes about the practice and funding difficulties. … ”  Read more from Inside Climate News.

The most recent microplastic removal technologies and why they’re important

“Microplastic pollution has grown from an environmental concern to a widespread global issue. These small synthetic particles, measuring less than 5 mm, contaminate rainwater, oceans, soil, and even human blood and organs. Research suggests links between microplastic exposure and various health risks, including inflammation, cardiovascular problems, and developmental issues.  Conventional wastewater treatment plants often struggle to fully remove these pollutants, allowing them to re-enter the environment and water supply. This situation has led to increased research focused on developing effective and sustainable removal technologies. These advancements address an important challenge to ecosystem health and human well-being.  A promising trend in microplastic remediation uses natural materials for effective water treatment. Researchers are exploring the potential of abundant and non-toxic plant extracts as alternatives to synthetic chemicals. … ”  Read more from AZO CleanTech.

Coastal sewage may be hidden source of airborne microplastics

Published in Scientific Reports, the research examined the theoretical conditions necessary for aerosolisation of microplastics and nanoplastics (MNPs). The team looked at records over a two-year period for Plymouth Sound, combining data from sewage overflows with same-day and long-term meteorological and satellite data.  They found that on 178 days across the two years, sewage spills coincided with winds of at least 6.5m/s, which was deemed the threshold for MNP aerosolisation. Specifically, the conditions for blowing these MNPs back onshore towards the city of Plymouth were found to have occurred for almost 1,600 hours, or around 10 per cent of the period studied.  “Our study is the first to make the connection between water pollution and air quality, and raises the question about potential health risks,” said lead author Dr Lauren Biermann, lecturer in Marine Science at Plymouth University. … ”  Read more from The Engineer.

Tons of invisible plastic pieces lurk in ocean water

“What do human brains, placentas and dolphin breath have in common? Signs of plastic pollution in the form of tiny particles known as microplastics.  The ocean is also polluted with plastic, and the issue may be even more extensive than previously thought. A study published Wednesday in the journal Nature estimates the volume of nanoplastics, which are even smaller than microplastics and invisible to the naked eye, to be at least 27 million metric tons in North Atlantic seas — more than the weight of all wild land mammals.  “I’ve analyzed plastic in Swedish lakes, in urban and very remote air, but this was different,” said Dusan Materic, head of a microplastics and nanoplastics research group at the Helmholtz Center for Environmental Research in Germany and one of the lead authors of the analysis. “It’s a missing part of the plastics story that we are answering here.” … ”  Read more from the New York Times.
