Blog: The battle to save the Endangered Species Act

As wildfires blazed through Los Angeles, turning buildings and lives to ash, President Trump politicized the tragedy, blaming an endangered species. In a January 8 Truth Social post, Trump said—erroneously—that Governor Gavin Newsom caused the wildfires by keeping water from Southern California to save “an essentially worthless fish,” the delta smelt. … It turns out Donald Trump had a political score to settle. … In 2020, Newsom sued the federal government, successfully, to halt a Central Valley water infrastructure project that could help farmers but harm the smelt, thereby violating the Endangered Species Act (ESA).

California’s Hi-Desert Water District breaks ground on $103 million sewer expansion

The Hi-Desert Water District (HDWD) has broken ground on the second phase of a $103 million sewage collection system in Yucca Valley, California. … When completed later this year, the new system will convey an estimated 210,000 gallons of wastewater per day through 32 miles of new pipelines to the Yucca Valley Wastewater Treatment and Water Reclamation Facility. Commissioned in 2020, the facility is the region’s first centralized treatment plant and provides critical capacity for wastewater recycling and groundwater protection.

California district launches programs to promote water use efficiency

The Eastern Municipal Water District (EMWD) in Perris, California, has launched new programs aimed at helping residents and businesses use water efficiently amid conservation efforts. A new portal called ‘Landscapes for Living‘ is now available to help residents create their ideal outdoor living space while using water efficiently. … EMWD said it believes the approach can be a model for other water agencies across California and other states, focusing more on the promotion of aesthetically pleasing landscapes rather than just conservation and fear of rising water rates.

News release: Metropolitan board opens new path to increase region’s water supply reliability through local water exchanges

In a move to strengthen Southern California’s long-term water reliability, Metropolitan Water District’s Board of Directors this week approved a new framework that will allow local water agencies across the region to sell and purchase locally produced supplies among one another. Through the Local Supply Exchange Framework approved by the board on Tuesday (Aug. 19), Metropolitan will help facilitate an exchange of local supplies between its member agencies – providing potential new water sources for some communities, and an opportunity for other communities to financially benefit from investments in supplies and demand management programs they have already made.

Colorado wildfire agencies uproot trees to protect Fort Collins water

… [I]n the past decade-plus, wildfire, and its effects on the area’s water supply, has become an increasing concern for city and state officials. … Enter the multiagency partnership and cost-share funding collaborative created to assess the impacts of post-wildfire hazards on critical water infrastructure and to identify strategies to minimize these impacts before and after fires. … Weston Toll, watershed program specialist for the Colorado State Forest Service, said after the partners had “treated a lot of low-hanging fruit, we needed to start treating the right acre in the right location.”

Thousands of marijuana plants removed from California’s Sequoia National Park

CBS Sacramento Law enforcement removed an illegal marijuana cultivation site where more than 2,000 plants were located in California’s Sequoia National Park last week, officials said on Thursday. … The same cultivation site was raided last year, but it was not rehabilitated until this year due to the presence of hazardous chemicals. National park officials reported damage to the site, such as diverting water from a nearby creek and installing irrigation lines. Officials said a significant amount of vegetation was cleared from the site and several large pits were built to store the diverted water.

Public asked to take part in Tehama County groundwater survey

… The Tehama County Groundwater Commission and the Tehama County Flood Control and Water Conservation District Board of Directors, serving as the region’s Groundwater Sustainability Agency (GSA), continues to work on the county’s state-required Groundwater Sustainability Plan (GSP). … Since the start of the GSP process, the county’s GSA has been plagued with issues associated with the plan, its development and implications. The 2023 Tehama County Grand Jury in its findings determined the fee assessment of .29 cents an acre placed on well owners in the county was faulty in the areas of inequitable fees, inadequate communication, accountability and other issues.

Thursday Top of the Scroll: Plan for California’s largest reservoir in decades gets big funding boost

The effort to build California’s largest new reservoir in decades received a welcome commitment of cash on Wednesday — nearly $220 million — which will help keep the project on track to break ground as soon as next year. Planned for 70 miles northwest of Sacramento, the proposed Sites Reservoir won the bulk of the funding because plans to expand the Los Vaqueros Reservoir in Contra Costa County fell through, freeing up money in the state’s 2014 water bond. The remainder of the money for Sites came from last year’s state climate bond.

Is Colorado ready for forced Colorado River cuts? State official says it might be time to develop a plan.

Colorado water officials announced Wednesday a rough plan to figure out how the state would handle an unwelcome specter in the Colorado River Basin: forced water cuts. Mandatory water cuts are possible under a 100-year-old Colorado River Compact in certain circumstances, mainly if the river’s 10-year flow falls too low. It’s a possibility that is one or two “bad years” away, some experts say. Colorado, however, does not have a clearly defined plan, or regulations, for how exactly it would handle such forced water cuts. … If the river’s flow falls below a 10-year rolling average of about 82.5 million acre-feet, the Lower Basin states — Arizona, California and Nevada — could demand that the Upper Basin send more water downstream based on the 1922 Colorado River Compact. In the water world, this is often called a “compact call.”

DWR Director: Delta Conveyance Project key to modernizing California’s State Water Project

Karla Nemeth, the Director of the California Department of Water Resources, says the Delta Conveyance Project is a crucial step in updating the State Water Project, which has been serving Californians for decades. … California’s water policy has evolved significantly since the 1950s with increased focus on environmental protection and equitable access to water. To address these complexities, officials say that revitalizing the State Water Project is seen as a key step towards ensuring water resilience. … Governor Newsom has called the Delta Conveyance Project “one of the most important climate adaptation projects in the country.”

Moving day for a rare Colorado trout

… The Uncompahgre strain of Colorado River cutthroat trout, which is unique to the upper Dolores River watershed in extreme southwest Colorado, lives in Wildcat Creek, and the fear on the part of biologists with Colorado Parks and Wildlife was that the Stoner Mesa Fire — which, as of Wednesday, August 20, had consumed almost 9,000 acres and was burning out of control — would not only have immediate impacts to the native fish, but also leave a lasting toxic legacy. So, ahead of the fire’s path, CPW work crews, along with biologists crews from the San Juan National Forest, electroshocked the remote reaches of Wildcat Creek and removed 266 native cutthroats.

Climate change amplifies extreme rains more than light precipitation, study finds

Climate change enhances extreme rains more than the ordinary drizzle. New research shows that frontal rain increases the most, and illustrates why extreme rains caused by other phenomena are not equally affected. … In a recent study published in Geophysical Research Letters, she [Kjersti Konstali, University of Bergen] and her colleagues looked into the mechanisms making the heaviest rainfall not just more extreme, but more extreme relative to not quite as extreme rainfall. … The wettest days occur when cyclones march in with fronts and an atmospheric river—a powerful troika now and in the future. But of the three, the front causes the largest increase.

Reduced Lake Pillsbury water release ‘surprises’ Potter Valley ranchers, farmers

A planned-for reduction in the amount of water Pacific Gas & Electric Co. is releasing from Lake Pillsbury caught Potter Valley farmers and ranchers off guard earlier this month during a key point in the summer growing and ranching season. PG&E says stakeholders should have been expecting the dip in water pressure, which occurred on Tuesday, Aug. 5. … As the Potter Valley agricultural community panicked over keeping cattle and crops sated, rumors erupted on social media that PG&E had begun cutting off the water supply from Scott Dam in advance of the structure being torn down as part of the decommissioning of PG&E’s Potter Valley Project, which includes a shuttered hydroelectric power plant.

There’s a ‘lake’ of oil under L.A.’s soon-to-close refinery. Who’s going to clean it up?

… For almost 40 years in the middle of the 20th century, workers at an oil refinery with connected facilities in Wilmington and Carson buried truckloads of slop oil and acid sludge directly on site. Decades later, much of that waste is still in the soil and water table, state records show. Phillips 66, which  now owns the century-old refinery, will idle the plants by the end of the year. …  Among the pollutants in the groundwater under the Carson and Wilmington facilities, overseen by the Los Angeles Regional Water Quality Control Board, are lead from buried waste and dangerous levels of per- and polyfluoroalkyl substances (PFAS) from foam used to fight fires at the refinery.

View of Merced County flood recovery depends on whether you can go home at night

On the one hand, state and federal agencies pledged more than $40 million to the recovery and future protection of Planada, the tiny farm town swamped by floods in 2023. Multiple agencies and helping organizations were mobilized and tasked with rebuilding the 840 homes lost after Miles Creek busted its banks south of Merced. On the other hand, more than two years is a long time to wait to get back home. Add to that what some say has been poor communication and a lack of transparency and residents are frustrated. … On top of their long, frustrating wait, residents fear they could be flooded out again if Miles Creek isn’t kept clear and the region is hit by another string of atmospheric rivers.

New $2 million program aims to protect Hanford-area domestic wells

Landowners who rely on domestic wells for drinking water may be able to seek help from the Mid-Kings River Groundwater Sustainability Agency if the tap runs dry. In an Aug. 12 board meeting, the GSA unanimously approved a $2 million program to help owners repair wells damaged by excessive groundwater pumping and keep water flowing to residents. … In April 2024 the state Water Resources Control Board put the region on probation for lacking an adequate groundwater plan. A month later, Mid-Kings imploded after the Kings County Water District bailed and the county was left to pick up the pieces.

Opinion: AI needs water. Arizona’s Constitution says: Not so fast.

Tucson’s City Council’s August 6 vote to reject Project Blue was more than a local win, it was a line in the sand over how this city’s water and infrastructure will be used in the age of AI. Now, with developer Beale pursuing relocation to Marana, a nearby community whose water rights and public benefit protections could soon be tested. At the same time, the proposed Benson Aluminum Dynamics plant has raised its own concerns over large-scale industrial water use and unclear public returns. Together, these projects underscore that Arizona’s fight over how much public we give for private development is far from over.

Bi-state effort keeps record amount of pollution out of Lake Tahoe

Lake Tahoe’s clear waters are benefiting from a record-breaking effort to reduce pollution, according to a new report from California and Nevada. The report by the Lahontan Regional Water Quality Control Board found that an estimated 727,000 pounds of fine sediment; more than 5,800 pounds of nitrogen; and nearly 2,100 pounds of phosphorus were prevented from reaching the lake in 2024 — all annual record highs since the program began tracking these statistics in 2016. These pollutants can fuel algae growth and harm the lake’s clarity.
