Tuesday Top of the Scroll: U.S. water rates soaring, with Bay Area bills among highest in nation

Water rates in the United States have risen more than twice as much as groceries over the past decade, and more than 1.5 times the overall rate of inflation, which has left Bay Area residents with some of the biggest water bills in the nation, according to a new report. An analysis of the country’s 500 largest community water providers, published by the consumer advocacy group Food and Water Watch on Tuesday, cites the privately held San Jose Water Company as the nation’s most expensive water retailer. … Thirteen of the 25 most expensive providers are in California, with their rates averaging more than twice the national average. The authors of the report say the average national water rate hike of 62% between 2015 and 2025 is largely due to the need to upgrade aging infrastructure, treat water pollution and adapt to more extreme weather with climate change, on top of lagging federal water investments.

Arizona to study a second seawater desalination project

Arizona is investing nearly $8.5 million on a study of a seawater desalination project in Mexico, the second such Gulf of California proposal that the state’s water augmentation authority has agreed to investigate this year. The state Water Infrastructure Finance Authority board approved funds for the feasibility study at an Oct. 5 special meeting. The board also approved $5.7 million for study of option to purify water for reuse in Mexico, potentially to include treatment of water for use in Tijuana, Mexicali and San Luis Rio Colorado. All of the projects would lead to Arizona helping produce water for Mexico in exchange for some of that country’s Colorado River water, though the desalination plant may also include an option to pipe water north.

Election 2026: Is Proposition 45 a housing solution or developer loophole?

… The California Chamber of Commerce collected the signatures necessary to qualify Proposition 45 for the November statewide ballot, in an effort to overhaul the California Environmental Quality Act, commonly known as CEQA. The changes, if approved by a majority of voters, will help lower housing, energy and water costs, supporters say, by cutting burdensome regulations and making it easier to build everything from homes to reservoirs to solar farms. Environmental groups call the measure a giveaway to developers, and are lining up to fight it. The contest is expected to be the first clear indication in years about whether Californians are willing to rewrite environmental regulations — which they have traditionally supported — as concerns about housing prices, utility bills and other costs have soared to the top of polls.

Denver Water sees mixed results from watering restrictions in dry year

Denver Water leaders aimed to reduce customers’ use by 20% across the board this year in response to record-breaking drought. But so far, the customers of the state’s largest utility have fallen short. Through the end of September, Denver Water customers reduced their water use by 9%, according to Greg Fisher, the utility’s manager of demand planning. Three months remain in the year, and Fisher expressed hope that a full lawn watering ban implemented Thursday — accompanied by threats of steep fines — would help the utility meet its goal. … In total, customers used 10,800 acre-feet less water than normal so far this year, according to Denver Water. … The utility issued 2,000 warnings and levied 110 fines that totaled approximately $30,000.

Spring runoff may drive microplastic surges in Western rivers, study finds

Microplastic concentrations in Nevada’s Truckee River increased nearly tenfold during spring runoff, according to new research that offers a glimpse into how plastic pollution moves through some western waterways. Researchers with the Desert Research Institute sampled the river, which flows from Lake Tahoe through Reno and eventually to Pyramid Lake, during low flows in fall 2022 and again during unusually high spring flows in 2023. On average, they detected 0.4 microplastic particles per liter in the fall and 3.7 per liter in the spring. … [T]he new research highlights how much concentrations can change depending on river conditions — something the authors say water managers and researchers should consider when deciding when to sample.

Powerful El Niño could slam Southern California. Here’s how Los Angeles is preparing

As Southern California endures a dangerous October heat wave, Los Angeles officials are preparing for a potentially powerful El Niño season. At the new Los Angeles Department of Water and Power Emergency Operations Center, the warnings went out that the El Niño weather event that is forecast has the potential, with warmer ocean water, to deliver damaging weather conditions to Southern California. The National Weather Service said strong El Niño events can increase the likelihood of wetter-than-normal conditions across Southern California during the winter. … City officials said Los Angeles has already begun taking steps to reduce potential damage and protect property and roadways from possible storm impacts, particularly in the Palisades burn area.

Blog: Protecting California’s water from cyberattacks

In June, Iranian hackers breached California Water Service systems and claimed  they could have shut down water service to thousands of customers. According to Cal Water, those claims were false, but the next month, more water sector cyberattacks targeted systems in at least 12 states across the United States. While most impacts were relatively minor, in Minnesota, the hardest-hit state, a coordinated attack hit more than 30 water systems over two days. California appears to have largely been spared in this summer’s cyberattacks on US water agencies, but the threat remains. In late August, another group threatened the US with “unexpected and critical events in the energy, water, and telecommunications industries.”

Newsom vetoes tribal water‑rights and sacred‑site protections as Klamath Basin rivers run dry

… Newsom on Wednesday rejected the California Indian Freedom Act (AB 1881) and the Indigenous Water Rights Act (AB 2218), despite unanimous votes in both chambers of the State Legislature. … The timing coincides with severe conditions on the Scott River, a major Klamath Basin salmon stream. On Sept. 27, gauges near Fort Jones showed the river at 8 cubic feet per second, far below the state’s 33 cfs minimum for September. … Tribal leaders say the condition of the Scott River shows why AB 1881 and AB 2218 mattered. The bills would have given tribes a stronger hand in the water‑rights and permitting decisions that influence flows in the Scott and Shasta rivers. … A coalition … is calling on the State Water Resources Control Board to conduct a comprehensive audit of water use in Scott Valley.

Scientists seek new ways to protect Sierra Nevada meadows

Sierra Nevada meadows may cover a relatively small portion of the landscape, but scientists say they play an important role in supporting wildlife, storing water and maintaining biodiversity. Researchers and conservationists recently gathered at the University of Nevada, Reno’s Lake Tahoe campus to discuss what is known about these ecosystems and what still needs to be studied. The workshop, sponsored by the Tahoe Institute for Global Sustainability, brought together researchers from different fields to identify gaps in meadow research and explore ways to improve conservation and restoration efforts. … According to the UC Davis Center for Watershed Sciences, the Sierra Nevada contains more than 18,000 individual meadows covering approximately 280,000 acres.

Monday Top of the Scroll: California agencies use confidentiality agreements to keep some Bay-Delta science secret

California state agencies have quietly been using confidentiality agreements to keep some scientific data and discussions behind the Newsom administration’s updated Bay-Delta plan a secret, raising concerns about transparency in the rule-making process. The California State Water Resources Control Board is set to vote later this month on the updated Bay-Delta plan, a massive policy proposal that aims to balance water needs for communities and agriculture while protecting fish, wildlife, and the environment in the San Francisco Bay-Sacramento-San Joaquin Delta. … State officials have denied they are hiding anything and maintain the process has been transparent. The proposed update to the Bay-Delta plan heavily relies on voluntary agreements, deals negotiated between state agencies and major water users, such as farmers.

Arizona cities could tap into a water savings account to help with Colorado River cuts

Arizona needs to cut back on Colorado River use, and water managers are working on a new plan that would tap into an underground water savings account to help do that. As part of its response to record-low reservoir levels, the federal government is mandating water cutbacks for Arizona, California and Nevada. On top of that, the states are volunteering to cut back more water. To do that, they’re passing the hat, getting contributions from water users — like cities and farms — that add up to a larger total. Many of those users get money from the federal government to cut back on water use. But on Thursday, officials with the Central Arizona Project laid out the details of another strategy to help reach that goal. Some cities and private utilities in the Phoenix metro could promise to conserve water and, instead of money, get access to an underground backup supply held by the Arizona Water Banking Authority.

Project to reduce groundwater pumping near Friant-Kern Canal – damaged by excessive pumping – gets underway

A groundbreaking ceremony in southern Tulare County last week signaled the start of another chapter in the long and expensive effort to fix the sinking Friant-Kern Canal. Construction began on five new Friant Water Authority pump stations that will lift water out of the canal and into Tea Pot Dome Water District and Saucelito Irrigation District systems, reducing growers’ reliance on groundwater. The project is expected to cost $46 million and take two and a half years to complete. More than $500 million – so far – in local, state and federal funding has been dedicated to fixing the canal, which has sunk along a 33-mile section from about Pixley to the Kern County line due to excessive groundwater pumping. Friant is looking for up to $400 million more to start the next phase of construction.

Lake Oroville water level drops faster than previous years

After a long dry spell starting in early spring and lasting through the summer, Lake Oroville’s high-level streak came to an end this year. The lake currently sits at 752 feet in elevation, roughly 47% of its total capacity. However, as California Department of Water Resources spokesperson Jaden Torres noted, it remains at 85% of its historical level for this time of year, likely in part because of past droughts. … The other question that remains is how the El Niño event will affect water levels in the north state. In September, Gov. Gavin Newsom declared an emergency in response to the incoming weather event, but how it will play out for Northern California is unknown.

Who will stop the draining of San Luis Valley’s water lifeline?

For decades, the San Luis Valley has been shipping out its irreplaceable aquifer water one potato at a time. While the trucks are filling with moist potatoes, the aquifer is draining to levels widely expected to hit historic lows at this month’s official measurement. … The local water conservation district is pushing a state-approved plan in water court that would charge a group of well-dependent farmers … $500 an acre-foot for water. … While high-profile special interests and advocates from Denver to Las Vegas to Los Angeles make noise about the crisis in Colorado River flows, the Rio Grande has quietly become one of the most troubled major rivers in the U.S. … Climate change and long-term drought have robbed the headwaters region of significant water. Farmers accelerated the drain by punching thousands of wells into the unconfined aquifer to water potatoes, barley, alfalfa and cattle.

Senate committee advances desalination reauthorization bill

The U.S. Senate Energy and Natural Resources Committee has advanced legislation that would extend federal support for desalination projects and research, including grants for large-scale facilities and pilot testing of emerging technologies. The Desalination Reauthorization Act, introduced by Sens. Alex Padilla (D-Calif.) and John Cornyn (R-Texas), was ordered reported by the committee Oct. 1 with an amendment in the nature of a substitute. The legislation would extend the Bureau of Reclamation’s authority to provide grants for desalination projects, which is scheduled to expire this year. It also would allow the programmatic approval to cover public-private partnerships and prevent Reclamation from imposing an administrative cap on individual project funding, allowing eligible large facilities to receive the full 25% federal cost share.

No single failure caused Palisades, Eaton fires, report finds

No single failure explains the devastation of the Palisades and Eaton fires that burned through Los Angeles County in January 2025, a new report concludes. Instead, the blazes exposed weaknesses across a system never designed to combat a wind-driven conflagration that spread from structure to structure at sweeping scale. The 723-page report dropped Friday morning. Commissioned by Gov. Gavin Newsom, it lands during his last months in office and just days after California’s Legislative session concluded. The report doesn’t pin the disaster on a single agency or decision. Its authors caution against seeking one culprit or one magic fix.  As a result, the report, which completes an analysis of some of the most deadly, destructive and costly fires in state history, raises a harder question: If responsibility is spread across an entire system, who is responsible for fixing it?

As Casa Grande commission approves massive data center, residents ask, ‘Why are we here?’

Casa Grande held its first public hearing on a data center, but it did not go as residents had hoped. Now, a data center, battery and natural gas facility — roughly the same size as New York City’s Central Park — will be allowed to take shape 8 miles from the city’s downtown. … The city has limited the Grande Valley Data Center complex to 300 acre-feet of water — or 97 million gallons of water use per year. That includes water for cooling servers in the facilities and for generating natural gas power on-site. We don’t know how much energy the site will use, if it will connect to the state’s grid, or when. Speakers were particularly disturbed by the project’s intended water use amid major Colorado River cuts that have impacted farmers in the community and across Central Arizona.
