California’s massive dam removal hit a key milestone. Now, there’s a problem

“Last year, after the historic removal of four dams on the Klamath River, thousands of salmon rushed upstream into the long-blocked waters along the California-Oregon border, seeking out the cold, plentiful flows considered crucial to the fish’s future.  The return of salmon to their ancestral home was a fundamental goal of dam removal and a measure of the project’s success.  However, a problem emerged. The returning salmon only got so far. Eight miles upriver from the former dam sites lies a still-existing dam, the 41-foot-tall Keno Dam in southern Oregon. The dam has a fish ladder that’s supposed to help with fish passage, but it didn’t prove to work.  While many proponents of dam removal say they’re thrilled with just how far the salmon got, most of the 420 miles of waterways that salmon couldn’t reach before the dam demolition still appear largely unreachable. This stands to keep the fish from spreading and reproducing in the high numbers anticipated with the project. Other migratory fish, including steelhead trout and Pacific lamprey, may face similar straits.The shortcoming has opened a new chapter in the decades-long effort to liberate the Klamath River, this one focused on Keno Dam. … ”  Read more from the San Francisco Chronicle.

Trump’s environmental protection budget cuts appear to target San Francisco Bay

“As director of the nonprofit Save the Bay, David Lewis has spent a lifetime fighting for resources – money to expand healthy tidal marshes, tighten wastewater standards, and push back on the kind of development that’s already covered miles of shoreline with landfill. But now, he feels like that work, and San Francisco Bay itself is under attack.  “The Trump administration is definitely targeting San Francisco for cuts to environmental protection and leaving some programs in other parts of the country, with full funding. It’s really vindictive. And it’s going to be very damaging to San Francisco Bay,” says Lewis.  He’s talking about restoration projects administered by the Environmental Protection Agency in regions around the country. While areas from the Great Lakes to the Gulf Coast to Chesapeake Bay keep their current funding, San Francisco Bay is targeted with more than $41 million in cuts. … ”  Read more from KGO.

Pending state subsidence guidelines give Valley water managers sinking feeling

DWR employees Katy Janes and Ky Dupuis, Groundwater Hydrogeologists in the Geology and Groundwater Investigations Section of the Division of Regional Assistance North Central Region Office, installed new telemetry equipment in groundwater monitoring wells in the Colusa Basin in Colusa County. Photo taken July 25, 2024.

“New subsidence guidelines from the Department of Water Resources are expected to drop on San Joaquin Valley water managers any day, a prospect that has them both hopeful and worried.  The intent of the guidelines is to provide clarity within the Sustainable Groundwater Management Act (SGMA), which requires overdrafted regions to enact plans to bring aquifers into balance by 2040.  One of SGMA’s primary goals is to halt subsidence, land sinking.  Excessive groundwater pumping has caused huge swaths of the San Joaquin Valley to sink, damaging canals, roads and increasing flood risks. Some areas have collapsed on such a large scale, the phenomenon can be seen from space, earning the nickname  “the Corcoran bowl.”  Subsidence, though, has been a tricky devil to manage.  Not all subsidence is the same. Some is reversible with substrata and aquifers that act like sponges, contracting in drought, refilling in wet years. In other areas, sinking is irreversible, particularly when pumping occurs deep below what’s known as the Corcoran clay layer that lies beneath the valley’s surface in intermittent patches. … ”  Read more from SJV Water.

“California’s Central Valley — one of the nation’s most critical agricultural regions and home to over 1.3 million people — is prone to flooding. Mapping the extent of winter floods has been challenging for experts, however, because clouds can obscure the view of satellites. Recent efforts to improve satellite flood mapping have been incorporated into a new study that offers insight into where winter flooding is occurring and inform how floodwaters can be used to replenish depleted aquifers.  The research, published June 4 in the Journal of Flood Risk Management, examined 20 years of satellite imagery to identify the extent and location of winter flooding in the region. The midwinter months of December through February were found to have the highest likelihood of floods, particularly when atmospheric rivers brought heavy rains when soils were already saturated. The study also identified areas where floodwaters fail to percolate through soils and offers suggestions for using the water to replenish rapidly depleting groundwater aquifers. By examining insurance claim data and overlays of floodwaters and buildings, researchers also found that flood exposure was actually higher, by value, for buildings outside of officially designated flood boundaries. The study’s findings can be visualized in three interactive maps. … ”  Read more from the Desert Research Institute.

How groundwater projects in Southern California provide pulse flows on the Feather River

Proposition 1 of 2014 dedicated $2.7 billion for investments in water storage projects, which the California Water Commission administers through the Water Storage Investment Program (WSIP).  Projects approved under the Water Storage Investment Program are funded based on the public benefits they deliver. One such benefit is supplying pulse flows to the Feather River to benefit salmon.  Three groundwater storage projects in the South San Joaquin Valley and Southern California have committed to providing these flows in exchange for funding. But how can a groundwater project in Southern California contribute to pulse flows on the Feather River? This question was answered at the May meeting of the California Water Commission, where Kristal Davis Fadtke, Environmental Program Manager at the Department of Fish and Wildlife (DFW), and David Okita, Special Consultant with the Department of Water Resources (DWR), explained the mechanics behind the pulse flows. … ”  Read more from Maven’s Notebook.

“Governor Newsom’s proposed trailer bill to streamline the Delta Conveyance Project (DCP) continues to garner support from legislators and a broad and growing coalition of 120 organizations—including labor, business, social justice advocates, local governments, and water agencies. Groups from the Inland Empire also offered a strong letter of support for the project.  The Governor’s budget trailer bill will help modernize California’s aging water infrastructure, protect water security for millions of Californians, and address the costly and redundant obstacles that have stalled critical projects like the DCP for years—all while maintaining strong environmental protections for Delta communities and habitats.  Twenty-eight legislators voiced their support for the bill to ensure that the State Water Project is prepared for the impacts of climate change … ”  Read more from Californians for Water Security.

Temporary victory: California senate rejects delta tunnel budget power grab

“Restore the Delta is celebrating a significant win for communities, the environment, and the democratic process. Today, the Senate Budget Subcommittee rejected the Delta Conveyance Project trailer bill package and reversed $351.7 million in proposed funding for the Voluntary Agreements.  This decision reflects growing concerns among legislators about the costs, legality, and rushed process behind the tunnel plan. It’s a strong signal that the Legislature will not allow environmental protections, public input, or fiscal responsibility to be cast aside for a massive, unworkable project.  “This is a huge win for the Delta, for California’s rivers, and for democratic process,” said Barbara Barrigan-Parrilla, Executive Director of Restore the Delta. “Legislators rightly stood up for public process, environmental review, and fiscal responsibility.” … ”  Read more from Restore the Delta.

Stockton-based conservation group calls for audit of billions in public spending by DWR

“At a time when Governor Newsom’s May revision budget proposal would slash overtime pay for caregivers, consumer access to care and nursing home oversight, the controversial Delta Tunnel that he wants to build is already costing taxpayers $1 million per day, according to the Department of Water Resources, or DWR.  Restore the Delta, a conversation group based in Stockton, has decided that it’s time for an audit. Last week, the group submitted a formal request to the Joint Legislative Audit Committee urging a full audit of DWR spending on the project formally known as Delta Conveyance Project, as well as its associated Voluntary Agreements.  “The request comes amid rising public costs, incomplete project plans, and growing legal and environmental concerns,” Restore the Delta said in a statement.  According to the letter, DWR will have spent nearly $1 billion on various iterations of tunnel project planning, with projected construction costs exceeding $20 billion before inflation or unforeseen expenses. … ”  Read more from the Sacramento News & Review.

Rich Kreps sounds alarm on California’s water storage failures

“Rich Kreps, pistachio grower and chairman of the American Pistachio Growers Board, is calling attention to California’s mismanagement of water resources, especially on the west side of Fresno. Speaking with AgNetWest, Kreps criticized decades of unfulfilled promises and failed infrastructure projects meant to bolster water storage.  “It’s awful,” Kreps said. “We keep paying for water storage—like we did back in 2018—but the money keeps getting diverted to projects that never materialize.” … ”  Read more from Ag Net West.

Solar arrays can aid grasslands during drought

New research from Colorado State University and Cornell University shows that the presence of solar panels in Colorado’s grasslands may reduce water stress, improve soil moisture levels and – particularly during dry years – increase plant growth by about 20% or more compared to open fields.  The findings were recently published in Environmental Research Letters. The paper outlines the potential benefits and challenges when photovoltaic (PV) arrays are located in grassland ecosystems. The findings are particularly relevant when considering drought in the arid west and the potential for future climate change.  While solar power systems are a key source of renewable energy, they reduce the amount of sunlight available for plant growth, which could impact these complex ecosystems in ways that reduce the wildlife they support, the carbon they store and the amount of forage they produce for livestock grazing. … ”  Read more from the Western Farm Press.

Underwater microphones capture 15 years of ocean change

“Scientists from Scripps Institution of Oceanography at the University of California San Diego were able to ‘hear’ the impacts of a marine heatwave and even economic slowdowns by analyzing 15 years of ocean sounds recorded off the coast of Southern California. The recordings, collected between 2008 and 2023, allowed researchers to hear whales moving north in response to a marine heatwave that began in 2014 as well as the massive decrease in noise from container ships during the 2008 financial crisis.  The findings, published June 5 in the Journal of the Acoustical Society of America, show that listening to the sea can be a tool for monitoring ocean ecosystems and even human economic activity.  Sound travels far and fast in the ocean. The loud, low-frequency songs of giant whales can be heard up to 1,000 kilometers (620 miles) away, and sound travels roughly four times faster in seawater than in air. This is why whales evolved to use their voices to communicate underwater. Unfortunately, human activities, such as global shipping, are also filling the oceans with noise that can make it harder for whales to communicate. … ”  Read more from Scripps.

Proposition 4: California’s historic $10 billion climate investment and path to resilience

“In the November 2024 election, California voters approved Proposition 4 – the Climate Bond, authorizing the state to issue $10 billion in general obligation bonds to fund climate resilience and environmental conservation projects.  The Legislature and Administration are currently debating how much of these funds will be available in the first year of allocations. The Governor’s 2025-26 January State budget proposal outlines his proposal for Proposition 4 allocations, but the final State budget and allocation of these funds will be negotiated with the Legislature until a final State budget is enacted by June 30.  In Nossaman’s California Water Views – 2025 Outlook, [Ashley Walker] discusses the opportunities that Proposition 4 brings to the water industry.”

One way Trump’s DOGE cuts could actually help environmentalists in the West

Author Tom Zoellner writes, “No big government infrastructure project made an imprint on the landscape and economy of the West more than the U.S. Bureau of Reclamation’s 20th century dam-building spree, which peppered 490 dams across the country, created an agricultural civilization dependent on federal hydrology civil engineering and brought about a welter of environmental difficulties after drying up dozens of once-healthy rivers.  Today, the agency claims a $1.4 billion budget to maintain its fleet of aging dams. It was perhaps inevitable that the Department of Government Efficiency, or DOGE, would seek to cut it down. Approximately 400 workers at the bureau — including dam tenders, emergency management specialists and hydrologists — received “reduction in force” letters in March, raising fears that poorly monitored dams could fail, creating catastrophic flooding. This, just five weeks after President Donald Trump stoked fears of mismanagement by ordering billions of gallons of water released from two Central Valley dams, against the objections of officials, water experts and farmers.  Turmoil in the federal dam management system represents potential disaster but also a prime opportunity: It offers environmentalists an opening to make a vigorous case for dam removal — a move that could save costs and please business interests while achieving a longstanding goal of getting rid of the most harmful and obsolete blockages on Western rivers.  … ”  Read more from the San Francisco Chronicle.

Elk Grove’s eco-friendly recycled water plan faces major setback amid rising costs

“A plan to irrigate Elk Grove parks, trees and plants with treated sewage water is in jeopardy. The recycled water was supposed to benefit the city’s last large-scale urban development, but city officials now say using recycled water won’t work.  A new 1,200-acre neighborhood near Bruceville and Kammerer roads in Elk Grove was supposed to be an example of environmental conservation. It is designed to be drought-tolerant by using treated sewage water in parks and landscaping.  “It’s really an environmental stewardship,” said public works director Jeff Werner. “Recycled water preserves the use of surface water and potable water.”  Many streets are already equipped with dedicated purple pipes to deliver reclaimed water, but now this eco-friendly Harvest Water project is going down the drain.  Werner is recommending that the city cancel the recycled water program in this southeast neighborhood. … ”  Read more from CBS News.

A creek on California’s most famous vineyard is the site of a contentious, yearslong fight

“A four-mile creek that runs through California’s most famous vineyard is at the center of a yearslong battle between a fourth-generation Napa Valley grape grower and major wine corporation Constellation Brands. After a 16-page appeal, repeated delays and even a fraud allegation, the conflict may finally get resolved this week.  The farmer, Graeme MacDonald, “grew up on and in” the creek, which babbles through land his family has owned since 1954. The property is part of the hallowed To Kalon Vineyard — made famous by California wine pioneer Robert Mondavi — and the unassuming creek is a geological star. Within its ancient bed, mineral deposits of gravel, sand and silt formed and spread, creating what’s known as an alluvial fan: rocky, fertile and well-draining soil that’s widely believed to be the best in the world for growing wine grapes. Known for producing some of the most complex and sought-after wines worldwide, these alluvial soils are famously found in renowned wine regions such as Burgundy and Bordeaux. … ”  Read more from the San Francisco Chronicle.

Keeping water flowing: Valley Water’s pipeline inspection and rehabilitation efforts

“At Valley Water, we’re committed to delivering safe, clean and reliable water to the people of Santa Clara County. A key part of that work is maintaining more than 150 miles of pipelines that carry raw, treated, and recycled water, some of which have been in service since the 1950s.  To keep this vital infrastructure in good shape, we’ve developed two programs: the Pipeline Maintenance Program and the 10-Year Pipeline Inspection and Rehabilitation Program. Together, these programs help us catch problems early, make timely repairs and plan for future upgrades.  Pipelines may be out of sight, but they’re always a priority. Even the most durable pipelines can wear down over time. That’s why we inspect and maintain them regularly. By catching problems early, we can make necessary repairs and upgrades before small issues become big disruptions. … ”  Read more from Valley Water News.

“Recently we spent a week in agriculture-based communities in California’s Central Valley. This post is the beginning of a series on what we heard, learned, and were surprised and inspired by from the people we spoke with there. It was a reminder to us of the central principle of journalism: The emotional and informative power of things you didn’t know, until you showed up.  The Central Valley is an important, and under-covered, part of America. It is important in obvious, dramatic ways. The Central Valley represents roughly 1% of US farmland, yet produces as much as 25% (by value) of all US-grown food. It is at the center of long-standing debates about California’s water supply, about its immigration policy, about its economic inequalities, even about the routes for its High-Speed Rail system.  The Central Valley also has an outsized place in American cultural imagery.

Amid ecological decline at Salton Sea, Audubon California finds 15% increase in shore birds

A new study by Audubon California has found a 15% increase in the number of shore birds at the Salton Sea, despite a prolonged ecological decline there.  The findings are surprising because in recent years as the area has gotten drier, there have been fish die-offs and fewer of the larger, fish-eating birds, like pelicans.  The study suggests the changes in the area’s ecology has specifically attracted more shore birds like the Western sandpiper.  “We’re seeing an increase in the availability in shore bird habitat,” said Dan Orr, leader of desert and Salton Sea science for Audubon California.  The birds have migrated from other parts of the region where development has shrunk their habitat, usually in mudflats along the coastal shores. … ”  Read more from LAist.

New algae system helps Arizona farmers grow better crops with less water

“Ed Curry is passionate about the green, red and yellow chile peppers he grows on his 3,000-acre farm in Pearce, Arizona, about 90 minutes southeast of Tucson.  He’s also passionate about saving water.  A new technology Arizona State University is analyzing and promoting has combined his love for spice and conservation.  “On the farm we have a saying: Make more crop per drop,” said Curry, who founded Curry Seed & Chile Co. in 1976 and is a member of Arizona Gov. Katie Hobbs’ Water Policy Council. “Our goal here is to cut our water usage whenever we can.”  Curry said he cut about 50% of his water usage in the 1990s by going to a drip system. More recently, he estimates he’s cut another 10% through a new soil service.  ASU and MyLand, a Phoenix-based soil health company, demonstrated how soil health innovation can drive measurable water conservation at Curry’s farm at an event on May 14.

The report also highlights financial sustainability (ranked sixth) as a companion challenge, indicating utilities’ dual focus on securing capital for projects and ensuring long-term financial viability.  The cost of providing water service has increased faster than inflation, leading to rising rates and affordability issues, which utilities must balance against the need to protect public health and maintain water quality.”  Watch video at Water World.

PFAS treatment and litigation strategies for water systems

“The Biden Administration took a firm approach when it came to regulating per- and polyfluoroalkyl substances (PFAS). The administration set Maximum Contaminant Levels (MCLs) for certain PFAS chemicals in drinking water, designated PFOA and PFOS as hazardous substances under the Comprehensive Environment Response, Compensation and Liability Act (CERCLA), and proposed listing PFAS as hazardous constituents under the Resource Conservation and Recovery Act (RCRA).  The U.S. Environmental Protection Agency (EPA) announced plans to rescind and reconsider some of the MCLs, but the two strictest, PFOA and PFOS, are expected to remain. The compliance deadline for drinking water systems to meet these MCLs has been extended by two years, from 2029 to 2031. This extension is still an announcement and not a final rule.  The established MCLs, and any future revisions, are subject to significant legal challenges. The “anti-backsliding” provision of the Safe Drinking Water Act is a potential basis for lawsuits, arguing that new regulations must maintain or improve public health protection. … ”  Read more from Water World.

If it seems like Section 10(a) just underwent a comment period not too long ago, that’s because it did. In 2023, under the Biden Administration, FWS solicited comments on proposed revisions to the regulations implementing that section, which were finalized last April. Now, the Trump Administration is seeking suggestions on how to further revise its ESA permitting rules.  The April 2024 rule revisions created a new type of agreement, called a “conservation benefit agreement,” that combines both safe harbor agreements and candidate conservation agreements under Section10(a)(1)(A) of the ESA to facilitate voluntary conservation of not-yet-listed species on non-federal lands.

“Trump administration officials have concluded that President Donald Trump has the authority to entirely abolish protected areas set aside as national monuments by past presidents, according to a legal opinion released Tuesday by the Department of Justice.  The May 27 document, which reverses a legal opinion issued in 1938, could be laying the groundwork for Trump to abolish or dramatically shrink national monuments, which confer federal protections to millions of acres of federal land, much of it in the American West.  Such a move would take the administration into untested legal territory.  “It signals that the president is prepared to do something dramatic and sort of at a scale that we’ve never seen before with respect to national monuments, which encompass many of our most cherished public lands,” said Justin Pidot, a professor at the University of Arizona’s James E.
