El Niño update for California: Meteorologists say this one could be ‘historically strong’
“Past El Niño years won’t help meteorologists determine what this winter will look like, the National Weather Service said in a Tuesday morning update, because conditions this year are not typical. An El Niño was declared in May, meaning sea surface temperatures are warmer than normal in the equatorial eastern Pacific. This region of the ocean typically drives large-scale atmospheric patterns that impact us locally, Courtney Carpenter, warning coordination meteorologist with the National Weather Service in Sacramento, said in the video update. Here’s what El Niño conditions mean for California, and what meteorologists predict winter in the northern parts of the state will be like, as of late November … ” Read more from the Sacramento Bee.
Living with earthquakes: How DWR maintains vigilance and resources to respond to the next jolt
“When a magnitude 4.2 earthquake struck near Isleton in the Sacramento-San Joaquin River Delta on October 18, it was a reminder of the threat posed to critical State Water Project (SWP) infrastructure by seismic activity. That infrastructure includes more than 1,100 miles of Delta levees which, if they were to fail during an earthquake, could cause a possible outage in water supply delivery to 27 million Californians and 750,000 acres of farmland. The temblor was followed by a 2.8 magnitude aftershock and, five days later, a 2.9 magnitude aftershock rumbled below Twitchell Island, less than a mile south of the first quake. All three quakes occurred on the Midland fault, one of several active fault lines that traverse the Delta. The initial jolt was strong enough to trigger a ShakeAlert, the Earthquake Early Warning System managed by the U.S. Geological Survey. … ” Read more from DWR News.
Fishery disaster determinations announced as main stem Sacramento River sees dismal salmon returns
“The Secretary of Commerce has determined that a commercial fishery failure due to a fishery resource disaster occurred in two California ocean and inland salmon fisheries, the Sacramento River Fall Chinook and Klamath River Fall Chinook, opening the door to disaster assistance from the federal government. The determination is in response to requests from Acting Governor Eleni Kounalakis. “Secretary of Commerce, Gina M. Raimondo, working with NOAA Fisheries, evaluates each fishery resource disaster request based primarily on data submitted by the requesting official,” according to a statement from NOAA Fisheries. … ” Read more from the Daily Kos.
Why does the Mokelumne River hatchery have a record salmon run this fall 2023 when runs at the Battle Creek (Coleman) fish hatchery are at record lows?
“Water Year 2023 (10/1/22-9/30/23) in the Central Valley was very wet, with exceptional hydrology. With the state’s salmon fishery closed and plentiful water there had been some optimism for the 2023 salmon runs. But there was also concern as to how much this year’s salmon runs would be affected by the poor water years 2020-2022. The Mokelumne River system is achieving hoped-for outcomes from its salmon management. Over 20,000 salmon adult salmon have been counted moving upstream past the Woodbridge counting facility. The counting facility on Battle Creek has counted only about 5,000 salmon, in a system whose adult return are generally far greater than those on the Mokelumne. What happened? … ” Read more from the California Fisheries Blog.
Sites Reservoir project finally gets green light, construction expected to begin in 2024
“Located just over an hour north of Sacramento in Glenn and Colusa counties lies 14,000 acres of grassland, streams and the main canal of the two counties’ shared irrigation district. It’s the site of the planned Sites Reservoir, which has long been eyed as a possible place to store excess surface water from across California. The project was first proposed in the 1950s, but failed — and was re-proposed several times since then. Now, after roughly 70 years and several iterations, the off-river storage basin west of the Sacramento Valley is being streamlined and moving forward. … ” Read more from Capital Public Radio.
Almond farming becoming less popular in California
“The amount of farmland devoted to growing almonds in California has decreased for the second consecutive year. A report given to the Almond Board of California shows almonds are becoming a less attractive crop for growers. The big picture: According to the report, almond acreage pulled out of production increased by over a third, while new plantings were down almost as much from the previous year. … ” Read more from the San Joaquin Valley Sun.

THE FUTURE OF EVERYTHING: The future of ecohydrology
Guest Alex Konings studies fundamental links between the global cycle of water percolating into the ground and evaporating into the skies and a similar cycle of carbon moving through the world, shaping ecosystems, droughts, and fires. These cycles are inextricably bound, she says, and understanding how they function individually and in tandem is key to life on planet Earth. These important cycles may be easily overlooked but they cannot be ignored, Konings tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
MARKETPLACE: Betting on Conservation
Most of Southern Nevada’s water supply — 90% — comes from the Colorado River, but its share is the smallest among the basin states, less than 2%. That became a problem when, in the mid-1990s, Las Vegas began growing quickly, adding more than 1,000 new residents every week and constructing the mega resorts and casinos it’s known for today. Enter Pat Mulory, the former general manager of both the Las Vegas Valley Water District and the Southern Nevada Water Authority. During her 25-year tenure as the top water manager in Southern Nevada, she would redefine conservation in the desert city and employ every tool at her disposal to acquire enough water for the thirsty city to continue to grow. In this episode, we talk with Mulroy about the existential crisis that Las Vegas and other desert cities face, and how Southern Nevada has been able to cut its Colorado River water use by 31% in the past two decades, at the same time its population has exploded. Through her career, we’ll get a picture of one city’s fight to stay alive at whatever cost, and what that means for the trade-offs that we all may have to consider to keep living where we want to live.
What’s up with water: The high cost of cheap water
What is the value of water? It’s an age-old riddle vexed by complexity and complacency. But what is the true value of functioning freshwater ecosystems, and what’s at stake without them?

BOOK REVIEW: The Three Ages of Water: Prehistoric Past, Imperiled Present, and a Hope for the Future
Justin Scott-Coe writes, “In The Three Ages of Water: Prehistoric Past, Imperiled Present, and a Hope for the Future (PublicAffairs, 2023), Peter Gleick provides a comprehensive understanding of water in readable form. His book, as he describes in a recent podcast, is the culmination of more than four decades of water science and policy work, both individually and through the Pacific Institute which he co-founded and where he continues to serve as Senior Fellow. The book, neatly summarized in its title, provides an exciting and fascinating tour of water’s journey from its creation soon after the Big Bang to your tap. Gleick skillfully explores water’s mysterious appearance on our planet and its role in shaping our environment, spreading humanity across the globe, and forming societies to manage and mismanage its use. He presents and discusses the positive and negative aspects of civilizations’ engagements with this vital, dangerous, and ubiquitous molecule, and he lays out a programmatic path for a positive water future. … ” Continue reading this book review at the Water Shelf.

Ricelands: Cultivating California’s Environmental Crop
Explore the significant role that California’s rice fields serve in ecological conservation. As natural wetlands have diminished over California’s history, these ricelands have become invaluable as surrogate wetland habitats, providing essential resources for millions of migratory birds during their seasonal flights. California’s ricelands are also part of innovative efforts to support salmon populations. By mimicking the natural river environments that salmon require for development, rice fields are being transformed into nurseries for young salmon. Join us as we investigate how agricultural landscapes are supporting wildlife conservation and what this means for the future of species preservation. Through interviews with experts and on-the-ground footage, we gain a comprehensive understanding of the integral connection between rice farming and habitat restoration.

Dam removal restores flows to historic Klamath River canyon
“When a US federal agency approved the largest dam removal project in US history late last year, Yurok tribe chairman Joseph James praised the many people who had sought environmental justice for Klamath River communities: ‘The Klamath salmon are coming home.’ Nearly a year later, work to take out the first of the dams scheduled for removal – Copco No. 2, the smallest – is now complete, restoring flows to the Klamath river canyon for the first time in 98 years. Between 1908 and 1962, four hydroelectric dams were built along a 645-kilometre stretch of the Klamath, where the river crosses the border between Oregon and California. For 20 years, communities and conservationists have fought for their removal, citing dramatic declines in fish populations, the knock-on effect for local fisheries and public safety concerns over water quality – in particular, the huge toxic algal blooms in the dam reservoirs. … ” Read more from Geographical.
PG&E moves forward with Eel River dam removal
“It now looks like two iconic North Coast rivers will flow dam free by the end of the decade. Just weeks after the first of four dams was removed from the Klamath River as a part of what will be the largest dam removal effort in the nation’s history, Pacific Gas and Electric Co. filed a 94-page surrender application to federal regulators, formalizing its plan to tear down its two dams on the Eel River that have blocked fish passage and reduced flows for more than a century. In the filing, PG&E said deconstruction work could begin on the dams as early as 2028, pending environmental review and regulatory approval. … ” Read more from the North Coast Journal.

Tehama groundwater update – cry me an atmospheric river
Liz Merry writes, “Lots of news from the Tehama Groundwater front. Four out of five of our Groundwater Sustainability Plans have been returned by the Department of Water Resources as “Incomplete”. The fifth GSP is still under review, but since it’s a copy and paste of the others, it will probably flunk, too. This is not surprising to anyone who has been paying attention, because the plans contain no steps to stop the overdraft of our aquifers or achieve sustainability.A quick review of the structure of our Tehama County Groundwater Sustainability Agency. It is made up of its governing body, the Flood Control Water Conservation District (a.k.a. our Board of Supervisors) and the Groundwater Commission, made up of 11 appointed commissioners. One member from each of our 3 incorporated cites, one each from three of our water districts, and one from each of the 5 supervisorial districts. … ” Read more from A News Cafe.
Wave of construction kicks off at Folsom Dam
“In early 2020, while the rest of the Sacramento region headed to their homes to ride out the COVID-19 pandemic, a long line of construction equipment under contract by the U.S. Army Corps of Engineers Sacramento District was instead heading to the jobsite. The first of eight dikes bolstering the west and south shores of Folsom Lake, Dike 8, gradually rose three and a half feet at the southern tip of the lake. Contracted workers donned safety vests, boots, and something new—the face mask—while work continued on Dike 8. “Weather doesn’t take off days,” said Gerry Slattery, Folsom Dam Raise program manager with the Sacramento District. “We realized we could ensure worker safety while continuing to advance this key piece of flood infrastructure. So that’s what we did.” Folsom Dam is not just one structure; it’s made up of a main dam, two wing dams (left and right), the Mormon Island Auxiliary Dam, and the eight dikes. Dike 8 was the first of all this infrastructure to be raised 3.5 feet, but far from the last. All of these components are scheduled to undergo a similar raise by 2028. … ” Read more from the Army Corps of Engineers.

It was six months after the November 2022 incident, and Wendy Ke didn’t want to miss the chance to tell them about the ashy material her family cleaned off their car and the asthma symptoms she only recently had developed. So her husband drove around the neighborhood until he found two agents. He rolled down the window and asked them to stop by their front porch. “I made a huge assumption that I lived in a safe place,” Ke said. But she’s no longer sure. … ” Read more from the San Francisco Chronicle.
San Mateo abstains from stormwater ballot
“The San Mateo City Council decided to abstain from voting on the city’s stormwater fee ballot measure that asks all property owners, including the city, whether to implement a monthly fee dedicated to funding stormwater infrastructure projects. The ballot measure, or the Community Flood and Storm Protection Initiative, stipulates that property owners can cast one vote for each parcel of land they own, and because the city owns 98 parcels, they would have been able to cast an equivalent number of votes. The ability for city councils to vote on such matters varies by jurisdiction, and some cities, such as Berkeley and Cupertino, have opted to vote on property-related measures. … ” Read more from the San Mateo Daily Journal.

As Water Board investigates two Carmel Valley sewage spills, Cal Am explains what went wrong
“In the immediate aftermath of a sewage spill at Carmel Valley Ranch on Aug. 6 and then another on Aug. 16, California American Water officials were out on the scene right away, seeking to contain the overflow. Paperwork moves much slower. Months later, in response to a notice of violation issued on Oct. 26 by the Central Coast Regional Water Quality Control Board, Cal Am has filed a technical report explaining what the utility believes happened. “The overflow incidents occurred as a result of fats, oils, and grease (FOG) blockages in the collection line, causing untreated domestic wastewater (sewage) discharging into several nearby storm drains that lead to the Carmel Valley River,” according to Cal Am’s Nov. 15 response. “The effort to unblock the collection line during the first incident was not completely successful, resulting in the second spill.” … ” Read more from Monterey Weekly.
Some Grover Beach residents want their City Council to rethink the city’s involvement in Central Coast Blue
“While some have disapproved of the project from the beginning, most followed suit after a Grover Beach staff report recommended increasing water rates almost 20 percent to help fund the Central Coast Blue recycled water project. “The study recommends annual water rate increases of 19.7 percent for years one through four beginning in January 2024 along with a 4 percent increase in year five,” the staff report for the Sept. 5 City Council meeting states. Frustrated with the news of higher water rates, former Grover Beach Mayor Debbie Peterson gathered others who felt the same and led a “March for Grover” on Nov. 13. “Grover Beach citizens are protesting their City Council’s Central Coast Blue plan to drastically increase water and sewer charges. From landlords to renters to homeowners to business owners, almost all agree that this project is too expensive,” Peterson said. … ” Read more from New Times SLO.

Carrot giants leave Cuyama Valley adjudication — but will that mend local ties?
“Two Bakersfield-based carrot giants have recently withdrawn from a controversial adjudication of groundwater rights in the Cuyama Valley, but it’s unclear whether the actions will allow them to avoid further fallout from their decision to initiate the proceeding. A group representing some of the area’s small farmers has called the retreats by Bolthouse Farms and Grimmway Farms “a surprising turn of events.” But rather than thank them for backing out, the group has called on the companies to use their influence to push for an end to the costly legal process. “While this move may appear to be a step toward resolution, (the companies’) land-leasing counterparts persist as plaintiffs, raising doubts about the corporations’ professed commitment to community and sustainability,” stated a news release Friday from Stand with Cuyama, which has organized a carrot boycott intended to pressure the companies to resolve the situation. … ” Read more from the Bakersfield Californian.

“From a small brick building in Garden City, Kan., 13 men manage the use of groundwater across five million acres in the southwest corner of the state, some of the most productive farmland in America for corn, wheat and sorghum. They serve on the board of Groundwater Management District 3, which since 1996 has overseen the pumping of 16.2 trillion gallons of groundwater — enough to fill Lake Mead, the country’s largest reservoir, twice over. The board is elected, but not by everyone: The only people eligible to vote are large landowners, a group of less than 12,000 people in an area of roughly 130,000.
