A surprising byproduct of wildfires: Contaminated drinking water

“Over the weekend, the Park Fire grew to more than 360,000 acres, prompting evacuation orders and warnings around Chico, California in Butte, Plumas, Shasta and Tehama counties. In the days ahead, Cal Fire will seek to contain the blaze to reduce harm to people, structures and the environment. However, months from now when the rains come and the fires are extinguished, a hidden threat could put communities at risk once again. … Around 60 to 65 percent of the United States’ drinking water comes from forested areas. As fires burn in these areas, they increase the risk of cancer-causing and toxic substances entering water supplies. An estimated 53.3 million U.S. residents who live in areas with significant wildfire risk may face damaged drinking water infrastructure from those flames. … ”  Read more from the Washington Post (gift article).

Charging California farmers for groundwater use could yield massive conservation gains, researchers find

“California farmers are willing to cut back on groundwater usage when their local governments start charging for this formerly free resource, new research has found.  Historically, Golden State farmers have kept their crops irrigated amid extreme heat and drought by tapping into groundwater beneath their properties — at no charge, other than the costs of pumping.  That practice has fueled concerns about the depletion of the state’s available water sources as climate change drives worse and more frequent drought.  Some local agencies, seeking to address those concerns, have begun to change their operating strategies in recent years, following the passage of a significant revamp to statewide groundwater regulations, according to the authors of a new working paper, published by the University of Chicago’s Energy Policy Institute. … ”  Read more from The Hill.

Bold moves needed for California agriculture: UC report details farming’s needs for climate resilience

“California should take urgent and bold measures to adapt its $59 billion agriculture sector to climate change as the amount of water available for crops declines, according to a collaborative report by University of California faculty from four campuses.  Published in the Proceedings of the National Academy of Sciences, the report provides a roadmap for more water capture, storage, and distribution systems that are in harmony with climate projections and ecosystems. It further considers how runoff and groundwater can be used repeatedly as it flows generally from mountainsides to coastal lands.  “The availability of water for consumption is decreasing because of climate change, partly due to increased evaporation and transpiration but also because we don’t have the system set up to capture and use the larger and more variable flows that are now the norm,” said Kurt Schwabe, a public policy professor at UC Riverside and co-author of the report. … ”  Read more from UC Davis.

Climate whiplash and hydropower: challenges and solutions in California’s Sierra Nevada Basins

Big Creek Hydroelectric Project. Photo by SoCal Edison.

“The area under study consists of four major basins in the central part of the Sierra Nevada in California: the Stanislaus, Tuolumne, Merced and Upper San Joaquin river basins, which contribute the most to the San Joaquin River flow. They host various hydropower projects, including the expansive Big Creek hydropower system which is ranked among the world’s largest complexes of its kind. Collectively these projects generate approximately 25% of California’s hydroelectric energy, with a total generation capacity of over 2700MW.  In addition to the largest climate variability in the US, the Mediterranean climate regime found in California gives the state a more extreme mismatch in water availability and demands. Electricity and especially agricultural water needs are greater during California’s hot, dry summers, while most of the precipitation arrives primarily as a few atmospheric river events in the northern part of the state, in particular in the Coast and Sierra Nevada mountain ranges during the winter. … ”  Read more from International Water & Power.

Bay-Delta longfin smelt wins Endangered Species Act protections

“The U.S. Fish and Wildlife Service officially listed the San Francisco Bay-Delta population segment of the longfin smelt as an endangered species under the Endangered Species Act Monday morning.  The longfin smelt was already listed as a threatened species under California’s Endangered Species Act, prohibiting the unpermitted possession, purchase, sale or take of the species. The service’s decision will now provide consistency between state and federal endangered species regulations, eliminating separate requirements from the state and federal levels.  The fish is 3.5 to 4.3 inches long with a translucent silver appearance on its sides and gut, while its back has an olive to iridescent pinkish hue. It lives about two to three years in bays and estuaries along the West Coast from Northern California to Alaska. The Bay-Delta longfin smelt occupies only the San Francisco Bay estuary and some areas of the Pacific Ocean. … ”  Read more from the Courthouse News Service.

New report released on Delta Drought Response Pilot Program

“The Delta Conservancy has released a final report on outcomes of the 2023 Delta Drought Response Pilot Program, an experimental program that was launched in order to test drought-resistant field management practices in the Sacramento-San Joaquin Delta Watershed.  Delta growers participating in the program received financial incentives to carry out a variety of water conservation practices as well as beneficial bird habitat practices on their fields. Specific practices included shifting crops, reducing irrigation, delaying harvest to protect nesting cover for birds, and intentional flooding of croplands for bird habitat. A total of 61 projects, encompassing 18,450 acres, were successfully enrolled in 2023. … ”  Continue reading from the Delta Conservancy.

Increasing river, Delta, and bay summer freshwater flows proves viable action

Tom Cannon writes, “In Above Normal water year 2024, an increase in summer freshwater flows released from reservoirs to the Bay-Delta estuary has proven a viable action to reduce threats to Central Valley fishes. Water management actions in early July heat waves alleviated extreme water temperatures that threaten the native fishes in rivers and the Bay-Delta. These actions can be described as adaptive management experiments to test their potential performance for the update of the State Board’s Bay-Delta Plan. … ”  Read more from the California Fisheries Blog.

Proposition 4, paradigm shifts and our planet – climate resiliency questions with State Senator Ben Allen

“Santa Monica’s State Senator Ben Allen recently successfully authored Proposition 4, a climate resiliency bond measure that will be on California’s November 2024 statewide ballot.  A 1996 graduate of Santa Monica High School and a former Santa Monica-Malibu Unified School District Board member (2008-2014), Allen has made a mark in the State Senate pursuing big picture legislation. I asked him about Proposition 4 and why he is committed to paradigm-shifting work.  QUESTION: What would your bill SB 867/Proposition 4 do — the “Safe Drinking Water, Wildfire Prevention, Drought Preparedness, and Clean Air Bond Act of 2024” — and why is it necessary?  SENATOR ALLEN: California is facing massive challenges relating to climate change, from our water infrastructure to wildfire prevention. With our 40 million people and drought challenges growing, our clean water supplies are going to be increasingly threatened. Investing in groundwater recharge and water recycling is critical to the long-term resiliency of our system. … ”  Read more from the Santa Monica Daily Press.

California Court affirms strict proportionality requirement for water rates under Proposition 218

“On July 15, 2024, a California Court of Appeal issued a ruling in Coziahr v. Otay Water District, ___Cal.Rptr.3d___ (2024 WL 3408627) (“Otay”).  The Court affirmed that water service rates subject to Proposition 218 (Cal. Const., art. XIII D, § 6, subd. (b)(3).) (“Prop 218”) must strictly adhere to the proportionality requirement in developing and adopting water rate structures, including tiered structures. The Otay decision underscores the necessity for water agencies subject to the limitations of Prop. 218 to base their rates on the actual cost of providing service to each parcel, rather than utilizing conservation goals or other non-cost-based factors as part of setting water rate structures.  Mark Coziahr, a customer of Otay Water District (“OWD”), challenged OWD’s adoption and use of a tiered water rate structure for residential customers on grounds that the rate structure violated Prop 218, specifically, its requirement that a property-related fee or charge “shall not exceed the proportional cost of the service attributable to the parcel.” … ”  Read more from AALRR.

The American West’s last quarter-century ranks as the driest in 1,200 years, research shows

“Three years ago, climate researchers shocked drought-weary Californians when they revealed that the American West was experiencing its driest 22-year period in 1,200 years, and that this severe megadrought was being intensified by global warming.  Now, a UCLA climate scientist has reexamined the data and found that, even after two wet winters, the last 25 years are still likely the driest quarter-century since the year 800.  ”The dryness still wins out over the wetness, big time,” said UCLA professor Park Williams.  The latest climate data show that the years since 2000 in western North America — from Montana to California to northern Mexico — have been slightly drier on average than a similar megadrought in the late 1500s. … ”  Read more from the LA Times.

California a botanical and climate change hot spot

“From coastal redwoods and Joshua trees to golden poppies and sagebrush, California is a global botanical hotspot. It’s also a place confronted with extreme heat, wildfires and crumbling coastlines. The state’s natural beauty and history of pioneering conservation efforts make it a test bed for protecting biodiversity in the face of current and future climate change, argues a study led by the University of California, Davis.  Published today in Proceedings of the National Academy of Sciences, the study, “Climate Change and California’s Terrestrial Biodiversity,” is part of a special PNAS issue on California sustainability. The article concludes that California’s 30 x 30 Initiative to preserve 30% of its lands and coastal waters by 2030, along with efforts to harmonize biodiversity conservation and renewable energy, is a promising step. It also highlights the need for California to shift away from its decades-long fire suppression policies and adopt fire strategies reflective of new fire regimes. … ”  Read more from UC Davis.

New conservation strategy to protect montane forests in Southern California

“The Southern Montane Forest Project has unveiled its Climate-Adapted Conservation Strategy for Southern California montane forests. This initiative aims to bolster the resilience of montane — or higher-elevation forests — with climate-informed actions. The strategy offers land managers a comprehensive guide to enhancing forest and community health with collaborations across different landscapes.  Southern California’s montane forests are vital to both humans and wildlife. These forests protect the upper watersheds of major rivers and supply about 40% of the water used downstream for drinking and agriculture. They also support Indigenous communities with food, fiber, and medicine and provide recreational opportunities to over 24 million people. Montane forests even capture carbon, prevent soil erosion, and serve as critical habitats for threatened and endangered wildlife. … ”  Read more from the US Forest Service.

As wildfire season approaches, phytoplankton take on fires’ trickiest emissions

“Just last year wildfires generated over 2.1 billion metric tons of carbon dioxide emissions around the globe. That’s the equivalent of driving 500 million gas-powered cars around for a year, according to the EPA. … In a satellite view of the planet, pockets of the ocean appear a bit murkier than the blue waters around them. Those spirals are full of microscopic plant life known as phytoplankton that produce much of the oxygen we breathe.  Tiny phytoplankton thrive on the surface of oceans, estuaries and rivers across the globe. They’re first on the menu for zooplankton and small fish. But aside from supporting the food chain, these nearly invisible organisms also take on a major mission: carbon dioxide sequestration that boosts the oceanic carbon sink effect. … ”  Read the full story from Inside Climate News.

Why a century-old beach building program could last ‘forever’

“How many times can a public beach vanish?  As many times as Congress pays to rebuild it — over a very long time.  A century after the federal government began bringing beaches back to life after they disappeared during storms, the U.S. finds itself at a crossroads with climate change.  Rising seas, storm surges and king tides are eroding popular tourist beaches and local economies on America’s coasts at a faster pace than ever. That’s costing taxpayers billions of dollars to pump sand onto beaches — only to see it disappear again. … ”  Read more from E&E News.
