State Water Board adopts Voluntary Agreements/Healthy Rivers and Landscapes Program …
Water Board adopts major overhaul to state water policy, drawing critics

“California water regulators approved a sweeping, yet controversial plan to manage the use of water in the state’s rivers on Thursday, with the goal of halting the ecological decline of the Sacramento-San Joaquin River Delta. Known as the Bay Delta Plan, the years-in-the-making policy lays out new terms for how much river water can be taken for cities and farms, from the Bay Area to Southern California, so enough is left to flow to the delta, a vast estuary and water supply hub for 30 million people. The plan, backed by Gov. Gavin Newsom, is centered on a novel arrangement that has spurred endless debate: Urban and agricultural water agencies can avoid the strictest of water regulations by agreeing to help restore overburdened rivers. The agreed-upon restoration work is seen as a way to win buy-in for the plan while improving river health, and ultimately the state of the delta. … ” Read more from the San Francisco Chronicle.
State adopts Delta Plan with mixed water quality strategies
“The State Water Board this week adopted what it is calling an “innovative new model to protect California’s Bay-Delta, water and wildlife.” The framework for the Bay Delta Plan – or officially, the Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Watershed – combines new flows, habitat restoration, science and enforceable rules to protect the Sacramento River and Delta, the agency said in a statement released after Thursday’s vote. It is a mix of both pathways debated over the recent years: the more flexible Healthy Rivers and Landscapes program favored by Solano County water and government agencies, which also was endorsed by Gov. Gavin Newsom and the State Contractors among others; and the stiffer regulatory pathway first presented by the state agency. … ” Read more from the Daily Republic.
Tribes, Delta groups & environmentalists slam state water proposal
“Tribal leaders, environmental advocates, and Delta residents gathered this week to condemn the State Water Resources Control Board’s decision regarding water agreements they contend will damage the Delta among other issues. They pledged further action to defend California’s water rights system, protect critical ecosystems, and ensure meaningful public participation in decisions affecting the state’s water future. At the center of the plan newly adopted by the State Water Board are so-called “voluntary agreements”, privately negotiated deals allowing powerful water districts to offer limited flow commitments and funding in exchange for exemptions from stronger, enforceable regulatory requirements. … ” Read more from the Manteca Bulletin.
Statement from Metropolitan Water District
Metropolitan Water District General Manager Shivaji Deshmukh writes, ““Metropolitan and partners across the state have worked for years to develop a smarter approach to building a healthier Bay-Delta and a more reliable water future for California, recognizing that flows alone are insufficient to protect the estuary’s ecosystem and the state’s water supply. The result – the Healthy Rivers and Landscapes Program – was intended to bring together additional water, habitat restoration and science, though a new governance structure and dedicated funding, to dramatically change how the Bay-Delta is managed. Implementation of the Healthy Rivers and Landscapes Program would be a landmark achievement in moving toward collaborative, science-based decision making to improve the health of the Bay-Delta while providing reliable water for California communities and businesses.
“Metropolitan appreciates the State Water Board’s commitment to a sustainable Bay-Delta and its efforts to include in the plan an implementation pathway that does not rely primarily on flows. However, Metropolitan is disappointed in the plan adopted yesterday. Ultimately, the State Water Board did not adequately incorporate the pathway as envisioned by the Healthy Rivers and Landscapes Program. Metropolitan will continue its review, including the changes incorporated into the adopted plan, to determine crucial next steps, and while doing that will continue to collaborate and engage agencies and partners. Metropolitan remains committed to the principles of the HRL Program and to finding solutions together. Southern California’s water future is closely connected to the health of the Bay-Delta, and our shared goals remain as important as ever.”

Could El Niño trigger an ‘ARkStorm?’ California’s flood risk explained
“The rivers in the sky hold the key. The strength, location and duration of atmospheric rivers – ribbons of water vapor that extend thousands of miles from the tropics to the western United States – will be the deciding factor in how much rain and snow falls in California this winter, and whether a disastrous “ARkStorm” flood could conceivably occur, experts told USA TODAY. “Atmospheric rivers are the wild card for this winter,” Scripps Institution of Oceanography research meteorologist Marty Ralph told USA TODAY. “If we get atmospheric rivers back to back, that sets the stage for potential flooding.” The El Niño powering up in the Pacific is prompting fears of a calamitous California winter, with potential flooding of historic proportions. Could it cause an “ARkStorm” scenario? “I am concerned about this winter,” Daniel Swain, a climate scientist with the University of California Agriculture and Natural Resources, told USA TODAY. “Due to the very strong El Niño, the risk of a severe ARkStorm-like flood resulting from weeks of heavy precipitation is more likely in a year like this one.” … ” Read more from USA Today. | Read via Yahoo News.
With El Niño on the horizon, can California’s flood protection weather natural, political uncertainties?
“It’s shaping up to be a very wet winter for California,with forecasts calling for a record-breaking El Niño that could bring the potential for floods, along with heavy rain and snow. Around 7 million people and billions of dollars worth of infrastructure across the Golden State face the risk of flooding. State and local officials have taken steps to boost their defenses, from mapping flood zones to shoring up thousands of miles of levees. But residents face additional uncertainty that is political in nature, with major federal shifts on disaster resources including at the Federal Emergency Management Agency (FEMA) and the National Flood Insurance Program (NFIP). A new report released by the Securing California’s Flood Future panel has outlined how California’s flood protection systems need to adapt to this new reality. Nicholas Pinter is the Schlemon Professor of Applied Geoscience at UC Davis and co-chairs the panel. He spoke with Insight Host Vicki Gonzalez about navigating environmental and political turbulence. … ” Read transcript or listen to radio show at Capital Public Radio.
Blog: The water we keep this winter depends on who gets paid for it
Bilen Essayas writes, “A very strong El Niño is lining up for this winter, with NOAA putting the odds above 90 percent, and the official message is to get ready. The Water Commission took up recharge readiness at its September meeting, DWR and its partners are running a recharge-readiness webinar series through February, and the Governor’s September 21 emergency proclamation directs agencies to promote recharge under existing law. Most of that preparation is about physical capacity and legal access: permits, diversion infrastructure, flood safety, the plumbing that moves a wall of winter water onto land where it can sink. All of it is necessary. The question underneath gets less airtime, and it decides how much of that water California actually banks. It is whether a grower has a reason to flood their own field, and something to show for it once the water is in the ground. … ” Read more from Bilen Essayas.
Flood resiliency report calls for mandated flood insurance as part of multi-layered actions
“Requiring statewide flood insurance was one of five key recommendations in a recently released report on securing a flood-resilient future for California. “Since 2025 – more than any other time in the past 60 years – there has been uncertainty and instability in how disasters are managed in the U.S.,” the conclusion of the 74-page report states. “Flood disasters are not solely the product of extreme weather; instead, they are the cumulative result of decisions about how communities grow, how risk is mapped and communicated, whether households are insured, and the degree to which governments invest in mitigation before disasters occur. A durable and resilient flood future for California will require a coordinated approach that links flood-risk mapping, land-use planning, insurance, hazard mitigation, emergency management, and long-term recovery.” … ” Read more from the Daily Republic.
As unusual low-latitude storm approaches SoCal; Once again, record-warm and record-high ocean conditions persist along CA coast amid still-strengthening El Niño
“t has been a wild week along the California coast, and not in a good way. Ocean temperatures have now reached record highs along the entire California coast (and on both sides of the Baja California peninsula, for that matter) extending all the way north to Pt. Reyes or even Pt. Arena (in Mendocino County)–a significant expansion from the more SoCal-focused record oceanic warmth in recent months. Significant marine ecosystem disruptions are now being reported along with these balmily warm waters. Even more dramatic to the casual observer, though, have been the increasingly disruptive and damaging episodes of extreme high tides and coastal flooding/erosion in recent weeks. Over the past few days, southern California ocean water levels reached their highest heights ever recorded in any month–and in parts of northern California, exceeded at least October monthly records (if not more in some locations). Widespread coastal flooding collectively affecting at least hundreds, and perhaps several thousand, structures from the San Francisco Bay Area southward to San Diego has been reported. … ” Read more from Weather West.
Newsom orders coastal highway protections, eases environmental rules ahead of El Niño
“Gov. Gavin Newsom has ordered California agencies to identify stretches of Highway 1 vulnerable to winter flooding and landslides while temporarily easing environmental permitting requirements for projects intended to protect coastal communities from El Niño storms. On the Mendocino coast, Caltrans closed Highway 1 twice last winter for flooding near the Garcia River, north of Point Arena. The road closed Dec. 21, 2025, and again Feb. 24, 2026, Caltrans spokesperson Manny Machado said in an email Oct. 21. Newsom signed the order Tuesday at Crystal Cove State Park in Newport Beach. It creates a Highway 1 Task Force led by the California State Transportation Agency and the California Natural Resources Agency. The order covers all 656 miles of Highway 1 and names Big Sur, where emergency projects cost about $312 million from 2020 through 2026. It tells Caltrans to watch for landslides where the highway has slid before or has recent burn scars, and to put prevention work there first “to the extent practicable.” … ” Read more from Local News Matters.
Tehachapi-Cummings County Water District board reaffirms support for Delta Conveyance Works project despite growing concerns
“The Tehachapi-Cummings County Water District Board of Directors reaffirmed its support for the Delta Conveyance Works Project at a monthly meeting Oct. 21 despite growing concerns about the project’s viability. The long-embattled Delta Conveyance Project, which would essentially finish the State Water Project with a tunnel transporting water from the Sacramento River to the San Luis Reservoir, has faced significant opposition and legal challenges. Earlier this year the project hit its latest legal snag. At the end of 2025 the 3rd Circuit Court of Appeal affirmed a trial court’s ruling that the project’s validation action was too vague, a ruling that has hampered fundraising efforts for the project. … ” Read more from the Tehachapi News.
Recent ding against Merced subbasin’s previously OK’d groundwater plan has managers on alert
“Water managers throughout the San Joaquin Valley are closely watching the latest groundwater twist in the Merced subbasin, which could see the region headed back under the enforcement thumb of the Water Resources Control Board. Even though Merced’s groundwater plan initially got the green light from the Department of Water Resources in 2023, subsidence still isn’t being dealt with to the state’s liking. Consequently, the subbasin’s plan got an “incomplete” rating on a recent five-year review. That’s just one step away from “inadequate,” which would send it back to the Water Board and possible probation, which comes with a host of fees and reporting requirements. Merced’s three groundwater sustainability agencies (GSAs) have 180 days to address deficiencies outlined in an Oct. 8 letter from the DWR. “We have every intention of complying with the recommendations and requirements of DWR and are already working to do so,” Bryan Kelly, Merced Subbasin plan manager, wrote in an email. … ” Read more from SJV Water.
State refuses to declare golden mussel emergency because there is no “long-term solution”
“Kern County water managers and officials were left scratching their heads after the California Governor’s Office of Emergency Services (CalOES) refused to declare an emergency due to golden mussels because “…there is no identified long-term solution to eliminate or control the continuation of the Golden Mussel Invasion,” according to a letter from CalOES. Without an emergency declaration, local water agencies aren’t eligible for California Disaster Assistance Act funding to help defray what’s conservatively estimated to be more than $36 million in annual costs to combat the invasive pest. “I’ve never seen an answer like this,” said Kern County Supervisor Jeff Flores who helped lead the effort to declare a countywide emergency in response to the growing infestation last spring. “I didn’t know a declaration was predicated on known solutions. I thought it was for emergency relief. Our farmers need to be reimbursed for their costs and we need help toward finding a solution.” … ” Read more from SJV Water.

From California dreaming to California doing: Scaling corporate investment in water resilience
“California’s economy depends on a reliable water future, and the state faces a projected 10% water supply gap by 2040. For companies with a water footprint in California, investing in water resilience protects their facilities and supply chains, while strengthening the communities they serve. This business imperative was the focus of the fourth annual California Water Resilience Forum on Oct. 27 in San Francisco, hosted by the California Water Resilience Initiative (CWRI) and co-sponsored by Cox Enterprises. Corporate leaders joined public agency, nonprofit, and finance partners to assess progress and confront a challenge none can solve alone: building water resilience at the scale and speed California needs. “The model is working. Now, it’s time to scale it,” said Emilio Tenuta, Ecolab’s Senior Vice President and Chief Sustainability Officer. “Reliable water is the foundation for reliable growth.

Working group seeks to reconnect flows in lower Klamath Basin watershed
“Restoration of a healthy, sustainable watershed is one step closer with the first phase completed on the Lower Klamath Lake Reconnection Project. It has been more than a century since the Klamath River’s inflows into the Lower Klamath Basin were severed. Changes to the thriving ecosystem began with the installation of the railway in 1907, which cut off natural supplies to Lower Klamath Lake — just one year prior to the declaration of the area as the nation’s first protected wildlife refuge for migrating waterfowl. This diversion was the first of many disruptions to the natural watershed in the century that followed, resulting in glaring impacts that continue to plague the people and wildlife that inhabit the Klamath Basin today. … ” Read more from the Herald & News.
‘It’s all going to go’: Humboldt County reckons with the sea

Lahontan Water Board secures $4.1M to protect drinking water in South Lake Tahoe
“The Lahontan Regional Water Quality Control Board announced a proposed settlement that would protect drinking water supplies in South Lake Tahoe from a toxic groundwater plume linked to a former dry-cleaning site. The proposed settlement would require Seven Springs Limited Partnership and Fox Capital Management Corporation, the former and current owners of the property, to provide treatment for municipal drinking water wells and address pollution affecting the Tahoe Valley South Subbasin for a period of 59 years. The contamination, primarily from tetrachloroethylene (PCE), originated from dry-cleaning activities at the property between 1972 and 1979 that formed a regional groundwater plume. The plume extended from the State Route 89 and U.S. Route 50 junction toward the Tahoe Keys and has contaminated wells used by two local drinking water providers. To ensure residents receive safe drinking water, the providers and the board have worked together to either treat the wells contaminated with PCE or close them. … ” Continue reading from the State Water Board.

An artist’s lifelong love of rivers flows into a Santa Rosa gallery
“As an art student, Richard McDaniel was struck by a line from “Siddhartha,” Hermann Hesse’s novel about one man’s search for enlightenment: “The river continually flowed and yet it was always there; it was always the same and yet every moment it was new.” The paradox — something constant that is continually changing — became part of McDaniel’s master of fine arts thesis. Over the decades, it has also guided his work, drawing him to paint rivers and wetlands across California and the country, capturing their shifting beauty through seasons and environmental change. Now, those rivers, creeks and wetlands are the subject of “The Majesty of Water,” a four-part exhibition at Pepperwood Preserve. On view at the Dwight Center Gallery through July 2027, the show will change as the river does: Every two months, half the paintings will be replaced with new works, some of which McDaniel has yet to create. … ” Read more from the Santa Rosa Press Democrat.

Long Beach Utilities stopped the spill by rerouting sewage to bypass the line and is working on emergency repairs, and the city has called in a contractor to clean up what spilled. City crews tried to catch as much of the sewage as possible before it reached drainage systems that led to the ocean, but about 14,000 gallons ultimately reached the sea, forcing Long Beach to close its coastal waters — including bays and lagoons. … ” Read more from the LAist.
San Bernardino County partnership with Cadiz affiliate renews water pipeline fears
“San Bernardino County has partnered with a Cadiz Inc. affiliate to establish a public financing authority that could advance the company’s controversial Mojave Desert groundwater pipeline project, which has faced years of environmental opposition and litigation. The San Bernardino Water and Power Authority announced its formation Monday, Oct. 19, following an inaugural meeting on Oct. 5. The county Board of Supervisors unanimously approved the joint powers agreement with Fenner Gap Mutual Water Co., the Cadiz affiliate, on April 21. The partnership marks another potentially significant development for Cadiz, which has spent decades trying to bring its groundwater in the Cadiz and Fenner valleys, near Amboy, to Southern California communities despite fears that pumping could dry up natural springs and damage fragile desert ecosystems. … ” Read more from the San Bernardino Sun.
Calimesa water project marks milestone
“One year after local water board officials gathered beneath a tent in the rain to break ground on a regional water project, they returned to the same site under sunny skies to celebrate a new connection to the State Water Project — one designed to help replenish groundwater supplies and strengthen water reliability for communities across the San Gorgonio Pass. The Oct. 14 ribbon-cutting ceremony for the County Line Road Recharge Basin and Turnout Project brought together representatives from the San Gorgonio Pass Water Agency, San Bernardino Valley Municipal Water District, South Mesa Water Company and Riverside County, along with regional water leaders and elected officials. The project can replenish underground water supplies with up to 479 million gallons annually, according to the project announcement, helping protect drinking water supplies for approximately 18,000 residents. … ” Read more from the Yucapia News-Mirror.

Salton Sea Leadership Program: A pathway to conservation work
” … Kevin is a 2026 Salton Sea Leadership Program (SSLP) alum, and Melanie was one of the program’s guest speakers. With the 2027 program just around the corner, I spent three days with three alumni, including Kevin, to learn about the fieldwork they have been doing since graduating. Each year, over the course of four months, a cohort of 10 local residents participates in the Salton Sea Leadership Program to learn about environmental topics directly from researchers, engineers, and environmental organizations in the Coachella and Imperial Valleys working to protect the spaces plants, animals, and humans share. During our conversation, Kevin shared that he is gaining college credit through the College of the Desert’s Work Experience Program with UCR’s Center for Conservation Biology. When asked how he came to join the Center for Conservation Biology, Kevin said, “I met Dr. Lynn Sweet through my work at REI, but previously I met Melanie Davis through the Salton Sea Leadership Program”. The Salton Sea Leadership Program isn’t just a lecture series. It’s an educational internship taught by local researchers, engineers, and environmentalists, giving participants opportunities to meet the people doing on-the-ground work. … ” Read more from Audubon.

San Diego El Niño: The case for stormwater funding
“Emergency declarations. Unprecedented coastal flooding. King Tides. Kelvin Waves. This year’s event is on track to be the strongest on record—and San Diego’s water infrastructure, especially its stormwater system, is nowhere near ready for it. Here’s what to expect, what the City is doing, why our neglected system is in trouble, and what you can do to prepare. What is El Niño? The El Niño and La Niña cycles are the warm and cool phases of a naturally occurring cyclical pattern of weather called the El Niño-Southern Oscillation (ENSO) that originates in the tropical areas of the Pacific Ocean. These two phases create extreme shifts in global weather patterns, ocean conditions, and air pressure. The term El Niño dates back to the 1600s, when South American fishermen first noticed periods of unusually warm water in the Pacific Ocean. The full name they used was “El Nino de Navidad,” because the effects of El Niño usually peak around December. … ” Read more from the San Diego Coastkeeper.
Commentary: The Tijuana River sewage crisis keeps growing. Who is responsible?
Tania Navarro, community opinion editor at The San Diego Union-Tribune, writes, “The alarm bells are ringing. A strong El Niño is expected to bring heavy rain and high tides to the region this fall and winter, and it has already caused flooding in Newport Beach and flood warnings in San Diego County in recent days. Those of us who have lived through similar seasons know what that could mean at the border, where the Tijuana River reminds us that Tijuana and San Diego share the same place. The geography and the explosive growth of Tijuana’s population are not in America’s favor. The city has grown to nearly 2 million residents, and its infrastructure has struggled to keep up. Sewage systems, wastewater treatment plants and drainage systems are overwhelmed, and residents on both sides of the border can see and smell the consequences. Then there is the river. It has always been part of this landscape, flowing north across the border before reaching the Pacific Ocean through the Tijuana River Estuary. But the story of how we got here is important, because this crisis did not begin with the latest storm, and it cannot be solved by simply pointing south. … ” Read more from the San Diego Union-Tribune.

Commentary: Time to treat the Colorado River like business infrastructure

Poul Due Jensen, group president and CEO of Grundfos, and Camille Calimlim Touton, former commissioner of the U.S. Bureau of Reclamation, write, “The Colorado River is sending business leaders a clear warning: Ignore water constraint risks at your own peril. Like many other water systems, the infrastructure, policies and agreements that govern the river were built for a different era. One with fewer people, lower demand and a very different hydrology. Today, those assumptions have collapsed. The system is under severe strain, and the consequences extend far beyond water management. The Colorado River supplies water to 40 million people and supports an economic engine that drives an estimated 16 million jobs and more than $1.4 trillion in annual activity. When that foundation becomes uncertain, the impacts show up quickly through rising costs, constrained growth, delayed projects and supply chains under strain. … ” Read more from the Las Vegas Review-Journal.
Colorado River basin candidates wade into water politics, but winners are unlikely to make big changes
“In Nevada, Attorney General and Democratic candidate for governor Aaron Ford’s campaign has said Gov. Joe Lombardo, a Republican, “botched negotiations” over the future of the Colorado River. In neighboring Arizona, Rep. Andy Biggs, the Republican Party’s candidate for governor, has said Democratic Gov. Katie Hobbs has cost the state millions of gallons of water from the river. And the Trump administration accused Hobbs of “playing politics instead of working toward meaningful solutions” when the state filed a motion to join Nevada in its lawsuit against the federal government’s new framework for managing the river after offering no comment on the initial suit filed by the Republican-led state. None of the candidates’ campaigns responded to requests for comment from Inside Climate News. These barbs come in the waning days before the midterm elections, when six of the seven Colorado River Basin states will cast ballots to elect governors. … ” Read more from Inside Climate News.
Colorado River crisis puts water center stage in Arizona midterms
“Water has been a prominent issue in Arizona for decades. But it has rarely played such a featured role in campaigns. The rivals for governor have squabbled over a federal conservation plan for the Colorado River. The attorney general has accused her challenger of apathy about the state’s shortage. One congressional nominee has largely centered his appeal to voters on the slogan “water is life.” “It is something we’ve been talking about on the campaign,” former Navajo National president Jonathan Nez said in an interview. “But it’s coming directly from the citizens of Arizona, too.” … ” Read more from Cronkite News.

The world’s biggest cities are sinking. Is yours one of them?
“The warning, buried in an obscure government report this summer, was unflinching. The Defense Department’s vaunted network of research laboratories — whose scientists helped develop satellite communication, radar technology, and even the computer mouse — was in trouble. The labs lost a significant share of their staff last year, largely in response to the Trump administration’s efforts to thin the federal work force, the report found. Refilling critical positions was proving difficult due in part to President Trump’s demand that new hires be screened for their loyalty to his goals. The report, issued by the Pentagon, pointed to “potentially grave consequences for the future of national defense.” … ” Read more from Scientific American. | Read via Yahoo News.

Scientists across the country are still receiving grants; universities are still being funded. But beneath the surface, the system of federally funded science that helped make the United States a global superpower is under intense strain from Trump policies, jeopardizing the nation’s advantages in defense, medicine and technology, a New York Times examination has found. … ” Read more from the New York Times.
