GOP Reps say preferred alternative for Delta water project operations inappropriately prioritizes environmental goals at expense of water supplies

“In July 2024, the Bureau of Reclamation released a draft Environmental Impact Statement (EIS) for the long-term operation of the Central Valley Project (CVP) and the State Water Project (SWP) for public comment.  The draft document considers revised operations of dams, power plants, and related facilities of the Central Valley Project and Delta facilities of the State Water Project.  (More on these documents here.)  Twelve California GOP representatives have written the Bureau of Reclamation, NOAA Fisheries, and US Fish & Wildlife Service, expressing concerns that the preferred alternative analyzed in the documents inappropriately prioritizes environmental goals unrelated to Endangered Species Act compliance at the expense of municipal and agricultural water supplies.  They point out that the water projects were constructed for multiple purposes such as irrigation and drinking water, and neither state nor federal law makes the delivery of water for consumptive uses subordinate to environmental uses. … ”  Continue reading from Maven’s Notebook.

‘It’s complicated’: Old Farmer’s Almanac predicts wet, mild winter, but meteorologists question forecast

“The Bay Area can expect a wet and mild winter – if the prediction of the Old Farmer’s Almanac proves to be true.  But the reality of predicting an upcoming winter’s climate is “complicated,” said meteorologist Jan Null, and the Almanac has only been right between one-third and one-half of the time, based on his comparisons.  “Whatever they’re using, it’s unverifiable,” Null said.  The Old Farmer’s Almanac, which has been predicting the weather for the United States since 1794, forecasted that weather will be temperate across the country this upcoming winter, according to a press release.  Winter will be “warmer than normal” through most of California, with the coldest temperatures coming through between mid-December and mid- to late-January, according to the almanac’s weather report. … ”  Read more from the San Jose Mercury News (gift article).

Drought emergency lifted for parts of California

“Coastal and desert communities across California can breathe a sigh of relief. After a few wet winters, Governor Gavin Newsom on Wednesday ended a years-long drought emergency declaration for 19 counties across the state.  “As this week’s weather makes clear, California and the West experience extreme weather swings that exacerbate our water challenges and make it more important than ever that we build a climate-resilient water system. This targeted action is responsive to current conditions while continuing the tools and support for work underway to help future-proof water supplies in the most impacted communities,” Newsom wrote in a press release.  The new proclamation will roll back a number of water restrictions in Los Angeles, Orange, San Diego, Inyo, Sonoma, and other counties where about 70% of the state’s population lives. … ”  Read more from the Courthouse News Service.

REPORT SUMMARY: The Science of Non-native Species in a Dynamic Delta

“The Delta is home to over 200 non-native species and is among the world’s most invaded estuaries. These species, introduced by human activities, pose a significant threat to the ecosystem. The potential for more non-native species to arrive, coupled with factors like habitat alterations, pollution, and climate change, can make the Delta’s ecosystem more vulnerable to invasion.  Non-native species are recognized as a significant factor driving ecosystem change, as they can disrupt the food web, modify nutrient and contaminant cycles, affect the populations of other species, and alter habitat structures. Such changes significantly impact a wide range of ecosystem services, with native species being particularly affected.  The Delta Stewardship Council’s Delta Plan recognizes the significance of non-native species as a threat to the Delta ecosystem and mandates the restoration of a healthy ecosystem by promoting diverse populations of native species and reducing the risk of harm from invasive species. So the Delta Independent Science Board (Delta ISB) in 2021 assessed the scientific needs in the Delta to address the threat. … ”  Continue reading this report summary.

Conservation: A better year for water in the West

“In the western United States, Ducks Unlimited’s highest-priority conservation areas are the Great Salt Lake in Utah; the Klamath Basin along the border of southern Oregon and northeastern California; and the Central Valley of California. Together, the “Big Three” support the majority of the Pacific Flyway’s waterfowl and other wetland-dependent birds during various periods of their annual cycles. These ecosystems all receive highly variable amounts of precipitation from year to year. … [G]iven the vagaries of western weather—not to mention growing demands on water resources—DU and its partners are working to ensure these crucial habitats are more resilient during periods of drought by working with stakeholders to improve water-use efficiency and by finding long-term solutions to the region’s complex water challenges. Following is an update on the latest habitat conditions and conservation efforts currently under way in the Big Three. … ”  Read more from Ducks Unlimited.

More extreme heat + more people = danger in these California cities. ‘Will it get as hot as Death Valley?’

“On a recent sunny afternoon in Lancaster, Cassandra Hughes looked for a place to cool down. She set up a lawn chair in the shade at the edge of a park and spent the afternoon with a coloring book, listening to hip-hop music. … Hughes, a retired nurse, is among the Californians who are moving inland in search of affordable housing and more space. But it comes at a price: dangerous heat driven by climate change, accompanied by sky-high electric bills.  A CalMatters analysis shows that many California cities with the biggest recent population booms are the same places that will experience the most high heat days — a potentially deadly confluence. The combination of a growing population and rising extreme heat will put more people at risk of illnesses and pose a challenge for unprepared local officials. … ”  Read more from Cal Matters.

Soil moisture analysis to manage risks in earthen dams and levees

“The world’s dams and levees are essential infrastructure used to store water, control flooding, provide recreation and generate power. Dams and levee networks are designated as critical infrastructure and over their expected life exposed to multiple hazards, including flooding, storm surge, erosion, debris flows and damage to control equipment and gates. The exact number of dams and levees world-wide is unknown.   According to the AMBER Consortium’s Barrier Atlas there are an estimated 1.2 million in-stream barriers spread across Europe’s 36 countries and 147 rivers. Approximately 61,500 of those barriers are dams. The average age of the dams in the UK and Japan is over 100 years old.  Germany, Italy, and the United States have an average age between 60 – 70 years. Experts often use the 50-year mark as the “alert age” where additional monitoring and maintenance should be implemented to extend the life of the asset. In Europe there are no standardized flood protection levee datasets. … ”  Read more from Water Finance & Management.

CA tribes ask Newsom to sign bill on co-management of lands, waters

Failure to implement environmental laws shows what’s really in store for the endangered San Francisco Bay-Delta ecosystem

Gary Bobker, Senior Policy Director at Friends of the River, and Jon Rosenfield, Science Director at San Francisco Baykeeper. write, “Earlier this year, two eminent fish researchers wrote “California … is a world leader in having its endemic freshwater fishes likely to be driven to extinction by the end of the century.” We know the reason. California habitually fails to enforce environmental laws designed to protect our aquatic ecosystems. Following the state’s lead, federal agencies skimp on environmental safeguards and waive the meager protections they do offer any time protecting the public’s fish, wildlife, waterways, and water quality, gets in the way of diverting more water to meet California’s seemingly unquenchable demand.  For example, in late August  water diverters and their allies in Southern California and the San Joaquin Valley wrote letters to state and federal leadership requesting “suspension” of this year’s planned action to allow more outflow from the Delta to San Francisco Bay in the fall (known as “Fall X2”). The Fall X2 action is a required part of the federal (CVP) and state (SWP) water projects’ endangered species permits. … ”  Continue reading this commentary.

More water supply requires industry unity

Edward Ring, Director, Water and Energy Policy at the California Water Policy Center, writes, “Probably the most consequential and controversial water policy decisions in California involve how much water to pump out of the Sacramento-San Joaquin Delta and into southbound aqueducts, and we’re in the middle of another one right now.  For the last several years, as summer turns to fall, state and federal regulators reduce the amount of water that gets pumped south in order to help the Delta smelt, an endangered fish. This year is no exception. In what is referred to as the “Fall X2 Action,” the pumps are about to be throttled down again. Water agencies at the receiving end claim the reduction, set to last about two months, will cost them up to 400,000 acre feet.  The reason the state wants to let this much water escape into the San Francisco Bay is to improve habitat for the endangered smelt, but critics of this strategy claim that smelt haven’t been found in the area, making the action fruitless. They also claim that regulators have the authority to restore higher rates of pumping without requiring a protracted bureaucratic process. … ”  Read more from the California Water Policy Center.

California water wars – the fish-killing Delta tunnel boondoggle that wouldn’t die

Dan Bacher writes, “The struggle against the fish-killing Delta Tunnel, the zombie water boondoggle that keeps getting resurrected by state officials and the state and federal water contractors, continues. In the latest battle in the California water wars, the Environmental Justice Law and Advocacy Clinic at Yale Law School, on behalf of the Delta Tribal Environmental Coalition (DTEC), submitted a formal letter to the State Water Resources Control Board concerning the Department of Water Resources’ (DWR) latest attempt to modify expired water permits for the controversial Delta Conveyance Project (DCP). … ”  Continue reading at Red, Green and Blue

Cancer-causing chemicals found in bottled and tap water in Bay Area

“As public skepticism about water quality rises in the United States, more people opt for bottled or home-treated water instead of drinking straight from the tap.  But is this truly a safer choice?  A recent study examining water quality in California’s San Francisco Bay Area suggests it might not be.  The research, published in PLOS Water, found that tap water, home-treated water, and bottled water in the region all contained trihalomethanes (THMs), cancer-causing compounds formed during water disinfection. This issue likely extends beyond the Bay Area to much of the country. … ”  Read more from Newsweek.

Central Valley farms lead the way in water-saving irrigation

“In 2014, mounting concerns around California’s severe drought and increasing regulatory pressures gave rise to a collaborative effort between Sustainable Conservation, Netafim USA, and De Jager Farms to revolutionize water efficiency and nutrient management for dairy farms in the Central Valley.  Nate Ray, CEO of De Jager Farms, spearheaded this effort, proposing that his operation’s lagoon water be utilized through drip tape to sustain feed crops in place of traditional flood irrigation.  Ray began experimenting with the Subsurface Drip Irrigation for Dairy Effluent system shortly after the passage of the Sustainable Groundwater Management Act.  “SGMA, the framework of it, was in its infancy stages at that point that nobody really knew — we didn’t know if we were going to get our wells metered, nobody knew what the rules were,” Ray said. “We just knew that, to be good stewards of the land, to be sustainable for future generations, we were going to have to reduce the amount of water that we pumped out of the ground ourselves… ”  Continue reading from Valley Ag Voice.

California city hit by landslides was at risk for decades, and the slipping may not be stoppable

“Rancho Palos Verdes, a coastal community in the Los Angeles area, could be described as a geological ticking time bomb.  The affluent city sits atop steep cliffs overlooking the Pacific Ocean that, for hundreds of years, have been slowly shifting and giving way.  Now, that movement is accelerating. Whereas the ground slid downward 8 inches annually in years past, it has lurched 13 inches per week in some places between July and August.  The resulting landslides have ripped apart seaside mansions, buckled roads and forced utility provider Southern California Edison to cut electricity to nearly 250 homes to avoid the possibility of fires. … ”  Read more from NBC LA.

State’s dust busting efforts at Salton Sea ‘one-sided’?

“At the Salton Sea’s western edge, near Salton City, the efforts of the Salton Sea Management Program are starting to show promise. But as the western side of the lake begins to stabilize, a different story is unfolding at Bombay Beach on the eastern shore.  At the Clubhouse Site of the SSMP’s Vegetation Enhancement Project just outside of Salton City, grass bales laid out across acres of exposed lakebed have begun to serve their intended purpose. Vegetation is now sprouting between them and slowly covering the dusty landscape. This success has fueled optimism among SSMP officials, who believe they are seeing the kind of progress needed to combat the dust storms and environmental degradation that have plagued the area for years.   Just across the water at Bombay Beach, the optimism has turned to frustration. Here, the same grass bales sit exposed, with little vegetation to cover them, and the community remains unconvinced.

Grand Valley water managers have plan to outmuscle invasive species

“Grand Valley water managers have a plan to nip a potential zebra mussel infestation in the bud, with one irrigation district beginning treatment of its water this fall.  Officials are hoping to secure federal funding to treat the water that irrigators and domestic water providers pull from the Colorado River with liquid ionic copper, which kills zebra mussels. Mesa County plans to ask for the money through the U.S. Bureau of Reclamation’s Bucket 2 Environmental Drought Mitigation program.  Microscopic zebra mussel larvae, known as veligers, were found this summer in the Government Highline Canal, a crucial piece of irrigation infrastructure for the Grand Valley’s agricultural producers. If these aquatic invasive species become established, it could be disastrous for the region’s farms, vineyards, orchards and Colorado’s famous Palisade peaches. The fast-reproducing mussels, which are native to Eastern Europe, can clog water infrastructure and are incredibly hard to eradicate once established. … ”  Read more from Aspen Journalism.
