State zeroes in on the sinking San Joaquin Valley
“Newly released state guidelines on how to get a handle on subsidence, or land sinking, were received with mixed reactions after they were released by the Department of Water Resources on Thursday. The guidelines provide some basic, but pointed, advice on how San Joaquin Valley groundwater managers can best stop, slow or even reverse subsidence, which a 2014 report shows had cost billions of dollars up to that time in history. Managers should put more water, lots more, into withered aquifers to bring land elevations back up, according to the new guidelines. They should better understand the substrata of their regions in order to predict how over pumping will impact the land. And they should act regionally. One groundwater agency or water district can’t fix the problem without help from surrounding districts, the new guidelines state. … ” Read more from SJV Water.
The Winnemem Wintu Tribe welcomes 80,000 salmon eggs to McCloud river this summer
“The Winnemem Wintu Tribe, along with partners NOAA and CDFW, welcomes 80,000 salmon eggs to the Winnemem Waywaket (McCloud River) this summer as part of a groundbreaking mission to reintroduce salmon to the watershed. This is the fourth year of the project. The first batch of eggs was delivered on July 12th, with the remainder coming on July 26th, August 16th, and August 23rd, where the Tribe and partners will greet them with ceremony and prayer. The eggs, which originate from the Livingston Stone National Fish Hatchery, will be raised in a “Nur Nature Base,” a remote egg incubation system located on the McCloud River that provides a more wild-like rearing setting than conventional hatchery operations. The alevins and fry will have a chance to imprint to the natural rocks and plants of the river, practice swimming in a variety of currents and temperatures, and choose when to leave into the river, where they will either stay in the upper tributaries of the McCloud to feed and grow, or start making their journey downstream toward the ocean. Traps will be placed in the lower McCloud River to catch salmon and move them around Shasta and Keswick Dams to be released into the Sacramento River, near Redding. … ” Read more from the Winnemem Wintu Tribe.
BAY-DELTA PLAN UPDATE
New development on the Bay-Delta Plan
“The State Water Resources Control Board has significant control and authority over how water flows through the Sacramento-San Joaquin River Delta. The Delta is essentially the valve through which Northern California surface water passes through on its way to the ocean. A limited amount of that flow is diverted to the aqueducts for use in the Central Valley, Southern California and the Bay Area. For a number of years, the State Water Board has been in the process of updating the Delta water regulations. The existing rules have resulted in significant reductions in exports of water to people and farms, while not improving, and in some cases worsening, the condition of endangered fish species. The State Water Board is required to balance all of the beneficial uses of water, including water for people and farms, in their regulations. … ” Read more from the Milk Producers Council.
State Water Board releases controversial Bay-Delta Water Plan Update amid civil rights investigation
“The California State Water Resources Control Board (State Water Board) released its long-awaited proposed updates to the San Francisco Bay-Delta Water Quality Control Plan (“Bay-Delta Plan”), a critical policy governing water quality and ecosystem health for California’s largest and most imperiled estuary. The updates and revisions include “voluntary agreements” (VAs), in which powerful water districts commit to provide limited additional river flows and funding in exchange for regulatory exemptions. This approach is drawing sharp criticism from Tribes, environmental justice organizations, and conservation advocates, who argue it represents a step backward for ecological protection and water rights. The release of the plan updates come despite an ongoing Title VI Civil Rights Act complaint filed by the Delta Tribal Environmental Coalition (DTEC), comprised of the Shingle Springs Band of Miwok Indians, the Winnemem Wintu Tribe, Little Manila Rising, Restore the Delta, and Save California Salmon. The complaint is driven by the State Water Board’s failure to uphold basic environmental protections in the Bay-Delta, disproportionately harming Tribes and other communities of color. … ” Read more from Restore the Delta.
Water Blueprint for the SJ Valley applauds progress toward a healthier, more reliable water future
“The Water Blueprint for the San Joaquin Valley joins water agencies across California and Governor Newsom to applaud forward progress by the State Water Board for advancing an innovative approach to improve healthy rivers and landscapes throughout the San Joaquin Valley. The Blueprint strongly supports the goal of restoring ecological function in California’s watersheds while meeting the water needs of our farms, communities, businesses, and environment. s a coalition deeply committed to sustainable water outcomes, the Blueprint recognizes the potential of the Healthy Rivers and Landscapes Program now under consideration in the Bay-Delta Plan update. The program represents an opportunity to balance improved environmental outcomes and greater water supply certainty to the San Joaquin Valley, where water scarcity already threatens farms, communities, and disadvantaged populations, as compared to the flow-only alternative. … ” Read more from the Water Blueprint for the San Joaquin Valley.
POTTER VALLEY PROJECT DAM REMOVAL
PG&E submits plan to tear down Potter Valley Project

“For over a century, the Potter Valley Project has been funneling water from the wild Eel River to the Russian River Valley’s thirsty vineyards, towns and farms. But that engineered connection, sustained by a pair of aging PG&E dams in the hills of Mendocino and Lake counties, may soon become history. On July 24, PG&E formally submitted its Surrender Application and Decommissioning Plan for the Potter Valley Project to the Federal Energy Regulatory Commission, marking a pivotal step in the utility’s plan to walk away from the century-old water diversion system. The long-anticipated move follows years of public debate, environmental review and bitter divides between water users, conservationists and tribal leaders over the project’s future. … ” Read more from MendoFever.
Two dams in Northern California could be razed under PG&E plan
“Pacific Gas & Electric Co. submitted a request to federal regulators Friday to tear down an aging hydroelectric project in Mendocino and Lake counties, a $530 million demolition that would include removal of two dams on the Eel River. The Potter Valley Project, according to PG&E, is no longer financially fit for power generation. However, the project’s greatest asset has become the water it provides, and the beneficiaries of that water, which include cities and towns in Sonoma and Marin counties as well as the region’s celebrated grape-growing industry, have been on edge about losing supplies. The decommissioning plan that PG&E filed with the Federal Energy Regulatory Commission calls for preserving the project’s water-delivery system, which those worried about water were hoping for. Under PG&E’s proposal, a new agency run by local communities would take over some of the existing project facilities and continue water shipments. The agency, though, wouldn’t be able to ship as much water and would likely charge more for it. … ” Read more from the San Francisco Chronicle. | Read via MSN News.
Editorial: Two-basin solution offers water security
The Santa Rosa Press Democrat editorial board writes, “PG&E, which owns the plumbing connecting the Eel and Russian rivers, couldn’t find a buyer for the Potter Valley Project. It’s easy to understand why. The century-old hydro power plant at the northeastern tip of Mendocino County is obsolete. It hasn’t generated a single kilowatt of electricity in four years and would need millions of dollars in repairs before the turbines could be restarted. Even then, the Potter Valley Project would be a money loser. Yet it remains a vital source of water for Mendocino and northern Sonoma County. … ” Read more from the Santa Rosa Press Democrat.

CAPITOL WEEKLY: A chat with Jennifer Pierre of the State Water Contractors
We won’t use that old Mark Twain quote (that he probably never wrote anyway) but fighting over water has been California’s favorite pastime for at least 175 years. If you think norcal/socal baseball rivalries are bitter – try the socal vs. Delta water wars. One of the people tasked with managing that aqua drama is Jennifer Pierre, General Manager for the State Water Contractors – a statewide, non-profit association of the public water agencies that contract with the Department of Water Resources to receive water from the State Water Project. The SWP provides water for 27 million Californians and 750,000 acres of farmland. A UC Davis alumna with a bachelor’s in environmental biology and conservation, Pierre has 20 years of experience in Delta management and uses that experience to help improve water supply and operations for the SWC. She joined us to talk about challenges of climate change, issues from overpumping groundwater, and if DC and and California can make nice on Water Policy.

TALKING UNDER WATER: Small systems, big challenges: What’s ahead for water utilities
In this episode of Talking Under Water, Bob Crossen speaks with Elora Arnette, associate director of Water Finance Assistance, about the multifaceted challenges facing small water utilities in 2025. They explore workforce shortages, including the growing number of soon-to-retire operators and the difficulty in replacing them, particularly in rural communities. Arnette discusses how many small utilities rely on multitalented local staff and even second-career workers, but stresses that this model is not sustainable long-term. The conversation also covers funding cuts to state revolving funds, the growing threat of extreme weather events, and the resource limitations that prevent proactive planning. Arnette highlights available support options, such as discounted training and emergency planning services, and calls for strategic rate reviews to maintain system viability.

Riding the rapids on a free-flowing Klamath River after dam removal
“The largest dam removal project in U.S. history was completed along the Klamath River last year. The main goal was to restore salmon habitat and reclaim tribal lands. But it’s also providing new stretches of whitewater to enjoy. On a warm spring day, a group of rafters made their way down the Klamath River near the California-Oregon border. The region has long been popular among whitewater fans, hosting a healthy number of rafting companies that offer daily floats during the warmer months. But what makes this trip special is that, until recently, the section of river they were on didn’t exist. … ” Read more from Jefferson Public Radio.

Parcel owners are encouraged to review their parcel data. The authority is proposing a groundwater management charge to fund the implementation of its Groundwater Sustainability Plan and comply with the Sustainable Groundwater Management Act. Affected groundwater pumpers were previously notified by mail about the proposed charge, the basis for the proposed rate as outlined in a draft cost of service study, and the upcoming public hearing. The proposed charge would apply to agricultural groundwater pumpers, commercial operations including wineries, and public water supply systems. Rural domestic pumpers, categorized as de minimis extractors, will not be charged. … ” Read more from the Paso Robles Daily News.

Hundreds of spring-run salmon rescued after taking detour into Tuolumne River
“More than 1,200 adult spring-run Chinook salmon meant to return to the San Joaquin River ended up in the Tuolumne River instead, prompting a five-part rescue operation. The fish were originally released as part of the San Joaquin River Restoration Program. But cooler, cleaner water and improved habitat conditions on the Tuolumne appeared to draw the fish off course, according to officials from the Turlock Irrigation District (TID). “Once the pulse flows had ended the plung pool was a little cut off from the main stem of the river,” said Constance Anderson, communications division manager for TID. “So we had to figure out a plan to move them back into cleaner, cooler water.” … ” Read more from CBS News.
Lemoore farmers unhappy with lack of representation on groundwater agency
“Growers in northwestern Kings County are fed up with a lack of representation on their groundwater agency and what they say has been an excessively slow process to get their voices heard. The board of the South Fork Kings Groundwater Sustainability Agency (GSA) currently has five seats. It has been working since May to add two more to represent the northern portion of the GSA near Lemoore. Because the five existing seats are held by government agencies, the process to change the board configuration has been slow, said Johnny Gailey, manager of the GSA. But a document to initiate the change has been making the rounds to those agencies, which include the City of Lemoore, Empire Westside Irrigation District, Kings County, Stratford Irrigation District and Stratford Public Utility District. “It’s being circulated back and forth between attorneys of the different agencies and there are still edits being made to it; the draft is not final,” Gailey said during the GSA’s July 17 meeting. … ” Read more from SJV Water.

Santa Ana Water Board strengthens nutrient contaminant levels for Lake Elsinore, Canyon Lake
“In a move designed to improve water quality in Lake Elsinore and Canyon Lake, the Santa Ana Regional Water Quality Control Board today adopted stricter limits on nutrients that can lead to harmful algal bloom eruptions, threaten aquatic habitat and restrict recreational opportunities. The lakes in western Riverside County have long faced challenges related to excessive amounts of nutrients – primarily nitrogen and phosphorous – that fuel toxic algal growth and deplete oxygen needed for marine life, resulting in fish kills and posted advisories urging the public in affected areas not to participate in water-related outdoor activities. The Santa Ana Water Board initially adopted the Total Maximum Daily Loads (TMDLs) – which define how much of a specific pollutant a waterbody can tolerate and meet water quality standards – in 2004. The revisions establish interim and final numeric targets for chlorophyll-a, ammonia and dissolved oxygen to reduce nutrient loads from both external sources (watershed runoff) and internal sources (lake bottom sediments). … ” Read more from the Santa Ana Water Board.

U.S. and Mexico sign deal to stop sewage release into Tijuana River
“The United States and Mexico signed an agreement on Thursday to end the flow of raw sewage into the Tijuana River, which crosses the border into California and for years has contaminated and closed beaches and caused illnesses in both countries. The environmental cooperation comes at a time when the two countries have been otherwise sparring on issues like tariffs, immigration and drug trafficking. Every day, millions of gallons of sewage flow into the Tijuana River starting in Mexico and ending in California, where the polluted water is dumped in the ocean. The sewage frequently overwhelms wastewater treatment plants in both countries. The problem has worsened in recent years as Tijuana’s population has grown, treatment plants in both countries have fallen into disrepair, and climate change has fueled increasingly strong storms. … ” Read more from the New York Times.

Longtime lawmaker shapes the debate as Arizona grapples with dwindling water supplies
“Throughout two decades marked by drought, climate change and growing demand for water, Arizona’s leaders have fiercely debated an increasingly urgent problem: how to manage dwindling water supplies in an arid state. At the crossroads sits Rep. Gail Griffin, a savvy and quietly assertive lawmaker who has for years used her status as the leader of key water and land use committees in the Republican-controlled Legislature to protect property owners’ rights, deciding which bills live and die. Griffin’s iron fist has infuriated residents and other lawmakers worried that unfettered groundwater pumping is causing wells to run dry. She’s also drawn the ire of Democratic Gov. Katie Hobbs, who considered her the barrier to legislation that stalled this year despite having others at the negotiating table. … ” Read more from the Associated Press.
As Arizona becomes data center hub, utilities recognize ‘growing concern’ over energy demand
“The state’s largest utilities could see energy demand nearly triple if every data center that wants to set up shop in their service areas came to fruition, according to new filings. Arizona Public Service Co. and the Salt River Project are already seeing massive, unprecedented load growth — and dozens more data center projects are still waiting in their electric service pipelines. Those facilities house the physical equipment needed to power computing, and the utilities told state regulators that they are clamoring for immense demand. Both utilities saw customers break energy demand records earlier this month amid soaring temperatures in Phoenix.

Lake Powell faces critical power threat by 2026 as groundwater dwindles
“The U.S. Bureau of Reclamation is warning that Lake Powell may fall below its minimum power pool level by September 2026, a critical threshold that threatens the dam’s ability to generate hydroelectric power. Below this level, only emergency bypass tubes—never designed for constant use—could release water, but recent use already caused damage.

River District offers proposal on Western Slope water deal
“In an effort to head off concerns about the state’s role in a major Western Slope water deal, a Western Slope water district has offered up a compromise proposal to Front Range water providers. In order to defuse what Colorado River Water Conservation District General Manager Andy Mueller called “an ugly contested hearing before the CWCB,” the River District is proposing that the state water board take a neutral position on the exact amount of water tied to the Shoshone hydropower plant water rights and let a water court determine a final number. “Although we believe this would be an unusual process, the River District believes it would address the primary concern (i.e., avoiding the state agency’s formal endorsement of the River District’s preliminary historical use analysis) that we heard expressed by your representatives at the May 21, 2025 CWCB meeting regarding the Shoshone instream flow proposal,” Mueller wrote in an email to officials from the Front Range Water Council. … ” Read more from Aspen Journalism.
