\nInvasive plants threaten Delta waterways, treatments begin<\/p>\n

\"\"\u201cCalifornia parks officials will begin another season of herbicide treatments in the Sacramento\u2013San Joaquin Delta later this month, targeting invasive aquatic plants that clog waterways, threaten boaters and disrupt marinas and irrigation systems.\u00a0 Starting March 19, California State Parks\u2019 Division of Boating and Waterways (DBW) plans to treat thousands of acres across the Delta and its southern tributaries as part of its 2026 control program. The invasive plants include water hyacinth, South American spongeplant, Uruguay water primrose, Alligator weed, Brazilian waterweed, curlyleaf pondweed, Eurasian watermilfoil, coontail, fanwort and ribbon weed. \u2026 \u201d\u00a0 Read more from the Stockton Record<\/a>.<\/p>\n

Sea levels are already higher than we thought, according to new calculations<\/p>\n

\u201cFor decades, California has been bracing for the sea. Communities from Pacifica to Imperial Beach have fought over seawalls, buyout programs to move people away from shorelines, and the loaded politics of \u201cmanaged retreat.\u201d Now, a new study suggests researchers globally may have built these plans on a shaky foundation.\u00a0\u00a0Published Wednesday in Nature, the research from Katharina Seeger and Philip Minderhoud at Wageningen University in the Netherlands uncovered discrepancies in what most scientists thought they knew about how high the sea already sits at coastlines around the world.\u00a0 The researchers analyzed 385 peer-reviewed studies on coastal flooding and sea-level rise published between 2009 and 2025 \u2014 including dozens cited in the United Nations\u2019 most recent major climate assessments. \u2026 \u201d\u00a0 Read more from the LA Times<\/a>.<\/p>\n

Microirrigation School, starting March 30, offers guidance on maximizing water use efficiency and productivity<\/p>\n

\u201cIn a time of increasing water scarcity and regulatory complexity, enhancing irrigation efficiency and improving on-farm water management practices are critical for California agriculture. Microirrigation \u2013 using highly efficient, low-flow and low-pressure systems that deliver water and nutrients close to plants\u2019 roots \u2013 is one key solution.\u00a0\u00a0\u201cMicroirrigation is no longer optional in many agricultural production regions worldwide,\u201d said\u00a0Daniele Zaccaria, professor of agricultural water management for Cooperative Extension at University of California, Davis. \u201cIt is essential for producing more food per unit of water and for achieving higher fertilizer use efficiency, relying on greater application precision and pursuing improved environmental stewardship.\u201d\u00a0\u00a0Zaccaria is organizing the 2026 Advanced School on Microirrigation for Crop Production, offered in California for the first time, from March 30 to April 3 (register by March 25). \u2026 \u201d\u00a0 Read moire from UCANR<\/a>.<\/p>\n

Reps. Garamendi, Peters introduce legislation to combat drought, build local water infrastructure<\/p>\n

\u201cYesterday, Congressman John Garamendi (CA-08) a senior member of the House Transportation & Infrastructure Committee, Rep. Scott Peters (CA-50), Rep. Jim Costa (CA-21), Rep. Raul Ruiz (CA-25), Rep. Juan Vargas (CA-52), Rep. Mike Levin (CA-49) \u00a0introduce the Drought Relief Obtained Using Government Help Today (DROUGHT) Act, to help address the Western water crisis caused by severe and ongoing drought conditions affecting the Colorado River and its reservoirs.\u00a0\u00a0The DROUGHT Act would allow drought-impacted and underserved communities to both bring in additional federal funds and remain eligible for long-term, low-interest Water Infrastructure Finance and Innovation Act (WIFIA) loans. It does not affect the obligation of borrowers to repay their loans, the timeline for repayment, or interest rates of applicable loans.\u00a0\u00a0\u201cEvery Californian deserves access to safe, clean, reliable drinking water. I\u2019m proud to join Congressman Peters in introducing the DROUGHT Act to ensure communities have the resources and federal support they need to advance equitable, sustainable water infrastructure projects,\u201d said Rep. Garamendi. \u2026 \u201d\u00a0 Read more from Congressman Garamendi<\/a>.<\/p>\n

\nMeadows Rising: Restoring California\u2019s mountain heartlands<\/p>\n

California\u2019s 18,000 mountain meadows are more than beautiful landscapes \u2014 they are the green hearts of the Sierra, keeping our water clean, reducing flood and fire risks, storing carbon, and providing vital wildlife habitat. They are also sacred cultural sites for Indigenous peoples. But most of these meadows are in poor health, threatening the watersheds we all depend on. The Sierra Meadows Partnership is leading the charge to restore and protect these emerald jewels. With support from California\u2019s Wildlife Conservation Board, we\u2019ve already restored thousands of acres and built 70+ partnerships across 20 counties. And we\u2019re just getting started. Restoring mountain meadows is one of the most important actions we can take for climate resilience, biodiversity, and water security.<\/p>\n<\/p>\n

Improved water data saves time and water in the Russian River telemetry study<\/p>\n

California\u2019s water future relies on timely, accurate data and collaboration between the people who use water and the agencies that manage it. The Russian River Telemetry Study is a first-of-its-kind project exploring how real-time water monitoring can reduce reporting burdens for users while improving water management for everyone. The study, which runs from 2025 to 2027, tests telemetry equipment and develops approaches that work for both local water users and state regulators. This video introduces the study, shares perspectives from participating landowners and water managers, and explores how better data can help balance the needs of agriculture, communities, and the environment. The Russian River Telemetry Study is led by the Telemetry Research Unit at the California State Water Resources Control Board, with support from the California Water Data Consortium, Balance Hydrologics, and local partners.<\/p>\n<\/p>\n

\nRain adds billions of gallons to Lake Tahoe, highlighting the need for water management<\/p>\n

\u201cRecent rain and snowstorms have delivered a massive amount of water into the Lake Tahoe Basin, and while the lake itself is rising, most of that water is flowing across the forests, meadows, and neighborhoods that surround it.\u00a0\u00a0According to the Tahoe Regional Planning Agency, since Feb. 15, rain and snow have added an estimated 16 billion gallons of water to Lake Tahoe, according to the U.S. Geological Survey. While the lake spans roughly 190 square miles, only about 35 percent of that water falls directly on the lake\u2019s surface. Most precipitation falls across the surrounding 310 square mile watershed of forests, meadows, streams, and neighborhoods that drains into the lake.\u00a0 The intensity of recent storms and the visible dirt and sediment on roads highlight why stormwater management and water flow restoration projects are critical to protecting Lake Tahoe. Homeowners contribute by installing and maintaining Best Management Practices, while Team Tahoe partners through the Lake Tahoe Environmental Improvement Program implement larger solutions across the basin. \u2026 \u201d\u00a0 Read more from KTNV<\/a>.<\/p>\n

Scientists gather at Lake Tahoe to protect the world\u2019s largest trout<\/p>\n

\u201cAt the Tahoe City Marina, scientists from around the world prepared to board a research boat on Lake Tahoe. It was a sunny afternoon, but on the water, the air was still cold.\u00a0\u00a0The boat, named Liberty, is part of the research fleet used by scientists at UNR. It helps researchers collect data, study water clarity and monitor conditions in the lake. A second, larger research boat with space for up to 15 people is expected to arrive this September.\u00a0\u00a0As the boat moves into deeper water, the lake\u2019s clear blue surface surrounds the group. Research professor Zeb Hogan says Lake Tahoe is an important place to talk about giant trout.\u00a0 \u201cAnd so we\u2019ve come together to try to share information, to try to figure out ways to better protect these fish,\u201d Hogan said. \u201cAnd one of the reasons why being out here on Tahoe is so relevant is that Lake Tahoe used to be home to North America\u2019s largest cutthroat trout species.\u201d \u2026 \u201d\u00a0 Read more from KUNR<\/a>.<\/p>\n

The SNC board approves nearly $8.7 million in wildfire resilience grants at March meeting<\/p>\n

\u201cThe Governing Board of the Sierra Nevada Conservancy (SNC), a California state agency focused on improving the environmental, economic, and social well-being of the Sierra-Cascade region, awarded $8,649,243 in wildfire and forest resilience grants to 10 different projects in the Sierra-Cascade that will help protect natural landscapes and nearby communities from major disturbances, such as wildfire.\u00a0 \u201cGetting funds into the hands of our local and regional partners to reduce fuels in overly dense forests, widen and lengthen strategic fuelbreaks, and enhance critical ingress\/egress routes, which all help to protect communities throughout the Sierra-Cascade, has been one of our primary goals since voters passed the Climate Bond in 2024,\u201d said SNC Executive Officer, Angela Avery. \u2026 \u201d\u00a0 Read more from the Sierra Nevada Conservancy<\/a>.<\/p>\n

Yuba Water Agency and CDFW complete oily debris cleanup on Englebright Lake<\/p>\n

\u201cYuba Water Agency and the California Department of Fish and Wildlife\u2019s Office of Spill Prevention and Response have completed the containment and removal of oily debris from the U.S. Army Corps of Engineers\u2019 Englebright Lake following the Feb. 13 rupture of Yuba Water\u2019s penstock pipe above New Colgate Powerhouse.\u00a0\u00a0During the nearly three-week cleanup effort, crews installed large debris and oil booms in the upper stretch of Englebright Lake, about a mile downstream of New Colgate Powerhouse, to capture and hold floating debris. Barges equipped with an excavator and large bins were then used to collect and remove oily materials from the water. Smaller boats also supported debris removal by hand. \u2026 \u201d\u00a0 Read more from YubaNet<\/a>.<\/p>\n

Nevada Irrigation District Board to continue discussion on proposed water rates<\/p>\n

\u201cThe Nevada Irrigation District (NID) Board of Directors will continue its discussion of proposed water rate adjustments at its March 11 meeting, when Directors are expected to consider initiating the Proposition 218 process.\u00a0\u00a0Any proposed rate changes are guided by the District\u2019s commitment to setting fair and equitable rates that generate sufficient revenue to meet operational and financial obligations. An adjustment is necessary to ensure revenues keep pace with rising costs and to support the continued reliable delivery of water to customers.\u00a0\u00a0NID has not adjusted water rates since January 2021. In the years since, the District has maintained high-quality service while absorbing significant increases in expenses. Inflation, rising energy costs, and higher material and construction costs have all contributed to increased operating costs. \u2026 \u201d\u00a0 Read more from YubaNet<\/a>.<\/p>\n

With primary water source back online, Tuolumne County seeks funds for emergency reservoir<\/p>\n

\u201cWater is flowing again in the Main Tuolumne Canal following a weeks-long outage due to damage from winter storms that led to the declaration of a local state of emergency and served as a stark reminder about the fragility of Tuolumne County\u2019s primary water source.\u00a0\u00a0Pacific Gas and Electric Co., which owns and maintains the roughly 14-mile canal system of wooden flumes and open-air ditches that were originally built by miners during the Gold Rush, announced Friday morning that repairs had been completed ahead of schedule to the critical piece of infrastructure that provides drinking water to about 95% of the county\u2019s residents. \u2026 \u201d\u00a0 Read more from the Union Democrat<\/a>.<\/p>\n

Repairs complete on canal supplying majority of clean water to Tuolumne County residents<\/p>\n

\u201cThe canal that supplies most of the clean water for Tuolumne County residents has been repaired after recent winter storms caused significant damage to it.\u00a0\u00a0The Pacific Gas and Electric Company, who run The Main Tuolumne Canal, stopped water flow on Feb. 17 after 250 trees fell into and onto the canal due to strong winds, heavy rain and deep snow.\u00a0\u00a0About 95% of Tuolumne County\u2019s residents get their water from the canal. Residents were urged to reduce their water use until repairs could be made.\u00a0\u00a0County officials also issued a state of emergency in a push for more resources to repair the damage done by the trees that fell on the 14-mile canal, breaking parts of its wooden flumes. \u2026 \u201d\u00a0 Read more from KCRA<\/a>.<\/p>\n

\nBird flu rips through another beloved Bay Area species<\/p>\n

\u201cSince mid-February, biologists have been struggling to control an outbreak of avian flu in a colony of more than 1,300 elephant seals at A\u00f1o Nuevo, a state park 55 miles south of San Francisco. It\u2019s the first time the virus has been detected in marine mammals in California, and so far, the outbreak has been linked to at least\u00a030 seal deaths. Testing remains underway as scientists scramble to understand how the disease is spreading and what other species may be at risk.\u00a0 According to a new study, though, a local population of beloved peregrine falcons has likely been falling victim to the same strain for years. The study, published as a preprint on Feb. 14 by a team of scientists in Santa Cruz, Oakland, San Francisco and Idaho, has tracked the presence of falcons at dozens of nesting sites over 26 years. The research shows a precipitous decline of Bay Area peregrine falcons, including the suspected death last year of a famous bird who captivated audiences as they watched her raise her chicks atop UC Berkeley\u2019s Campanile. \u2026 \u201d\u00a0 Read more from SF Gate<\/a>.<\/p>\n

Proposed new wells will spread PFAS plume<\/p>\n

\u201cZone 7 Water Agency plans to drill new wells in southwest Pleasanton near the leading edge of an enormous plume of PFAS, a.k.a. \u201cforever chemicals\u201d, underlying the Tri-Valley. And they\u2019re pushing Pleasanton to join them.\u00a0\u00a0New groundwater modeling commissioned by Zone 7 appears to be very accurate in predicting groundwater levels based on historical data, but this is not the same as predicting PFAS plume movement. The model doesn\u2019t show how the PFAS plume grew from nothing 50 or 60 years ago (from recently confirmed sources) to its current titanic size: six miles long and two miles wide.\u00a0 A model that can\u2019t reproduce the historical plume movement is not useful in predicting future plume movement. \u2026 \u201d\u00a0 Continue reading from Pleasanton Weekly<\/a>.<\/p>\n

Western states pour cold water on federal Colorado River plans<\/p>\n

\u201cWater-starved western states say the federal government\u2019s plan to manage how to split up the Colorado River is doomed to be picked apart in court. If not, representatives from desert states like Arizona say some scenarios would force them to truck in water to keep some communities alive.\u00a0\u00a0After years of fighting between themselves, states with a claim to Colorado River water via a 1922 compact missed<\/a> a key deadline earlier this year.

Colorado River allocation debate could pose a massive impact for Arizona farmers<\/p>\n

\u201cThe debate continues over the new draft of Colorado River water allocations, as Arizona would receive large cuts to its allocation of river water.\u00a0\u00a0If that happens, the agriculture industry in the state could be devastated.\u00a0\u00a0The industry plays a huge role not only in the southwest but across the country, and it has already been hit hard by previous cuts.\u00a0\u00a0\u201cMy family has been farming here since 1919, so we got a little history here, so to say the least, this is probably the worst it\u2019s ever been,\u201d said Jace Miller, a Partner with Triple M Farms in Pinal County.\u00a0\u00a0Miller knows the ins and outs of the agriculture industry in Pinal County, a sector that is the most affected by allocations from the Colorado River.\u00a0\u00a0\u201cThe problem is agriculture has been the scapegoat for years in this state regarding water; anytime there was a shortage somewhere, take it from the farmer or rancher,\u201d Miller said. \u2026 \u201d\u00a0 Read more from Channel 13<\/a>.<\/p>\n

Arizona farmers turn to conservation as Colorado River cuts loom<\/p>\n

\u201cWith Arizona facing a proposed 77% cut to its Colorado River water allocation based on a recent proposal from the Bureau of Land Reclamation, farmers in Pinal County are turning to conservation methods to keep their operations running.\u00a0\u00a0Nancy Caywood, co-owner of Caywood Farms in Pinal County, said her operation is already feeling the effects of reduced water access due to increased drought.\u00a0\u00a0She said the proposed Colorado River cuts could make things worse for farmers like her, as she owns acres of land that rely on the water.\u00a0\u00a0\u201cIf there\u2019s further cutbacks on that farm, we might not have any water,\u201d Caywood said. \u2026 \u201d\u00a0 Read more from Channel 13<\/a>.<\/p>\n

Desalination might figure into Las Vegas water solution; early step announced in San Diego<\/p>\n

\u201cAn agreement announced late last week in San Diego could be the start of a new kind of water solution for Las Vegas and other cities in the desert Southwest.\u00a0\u00a0A desalination plant in San Diego County is working, but it\u2019s only running at about half-capacity because the process is expensive. The \u201cmemorandum of understanding\u201d signed last week would start the exploration of an interstate water transfer and exchange pilot program.\u00a0\u00a0That could mean that, someday, water produced by the desalination plant could be \u201cmoved\u201d to Nevada or Arizona. The agreement is early in the stages, and it hasn\u2019t been approved by everyone involved.\u00a0\u00a08 News Now reached out to a Southern Nevada Water Authority (SNWA) spokesperson, who said the memorandum was being reviewed, but it was too early to comment. \u2026 \u201d\u00a0 Read more from Channel 8<\/a>.<\/p>\n

2026 Utah legislature on Great Salt Lake, Colorado River and the environment<\/p>\n

\u201cThe announcement hit like a welcome thunderstorm in the drought. FOX 13 News was the first to report that Utah\u2019s Division of Forestry, Fire & State Lands had successfully won an auction for the bankruptcy assets of U.S. Magnesium, a company branded one of Utah\u2019s top polluters and located on the shores of the Great Salt Lake. The state wanted the water to help save the shrinking lake. Lawmakers rushed through $30 million in funding to make it happen.\u00a0\u00a0Rep. Jill Koford passed a major bill that seeks to solve a big problem of ensuring that water that is conserved actually makes it to the Great Salt Lake. It ensures that the water is released in a timely manner for the lake and gives the state more power to find water sources to prop up the lake. \u2026 \u201d\u00a0 Read more from Fox 13<\/a>.<\/p>\n

Lake Powell now on track for 5th-lowest runoff on record, per new projections<\/p>\n

\u201cLast month\u2019s precipitation improved Utah\u2019s water outlook somewhat, but Lake Powell\u2019s and Great Salt Lake\u2019s tributaries are still on pace to produce some of their worst spring runoffs in history.\u00a0\u00a0In fact, Lake Powell is currently on pace for its fifth-worst runoff on record, according to new projections released by the National Weather Service\u2019s Colorado Basin Forecast Center on Friday. The agency doesn\u2019t provide a similar comparison for the Great Salt Lake, but it warns that spring snowmelt runoffs could flirt with the bottom 10 runoffs in the many decades of tracking the Bear, Provo and Weber river basins, as well as Big Cottonwood Creek.\u00a0\u00a0\u201cSnowmelt runoff forecasts for Utah range from 21% to 83% of average,\u201d added Jordan Clayton, a hydrologist for the Natural Resources Conservation Service, in a water supply outlook the agency also issued on Friday. \u2026 \u201d\u00a0 Read more from KSL<\/a>.<\/p>\n

A record warm winter could send Lake Powell to a historic low. Flaming Gorge may be its lifeline.<\/p>\n

\u201cA cream-colored band lines the orange sandstone walls that rise above the blue-green waters of Lake Powell. The so-called \u201cbathtub rings,\u201d these chalky layers remind boaters zooming across the popular reservoir how far the lake has fallen.\u00a0\u00a0After two decades of drought and an exceptionally warm winter, those rings will likely soon span even wider as Powell continues to drop towards a record low.\u00a0\u00a0\u201cRight now the hydrology that we have in front of us puts us in a very, very precarious situation,\u201d said Gene Shawcroft, Utah\u2019s Colorado River negotiator.\u00a0 Utah just wrapped up its warmest winter on record. Salt Lake City broke its previous maximum average winter temperature by 2 degrees Fahrenheit \u2014 a significant increase, according to the Colorado Basin River Forecast Center. While the state received similar precipitation compared to last year, much of that fell as rain, leading to the worst snowpack since 1981 in parts of the state. Now, the water supply outlook is \u201cwell below normal,\u201d according to the center. \u2026 \u201d\u00a0 Read more from the New York Times<\/a>.<\/p>\n

\nEarth is warming faster than previously estimated, new study shows<\/p>\n

\u201cPlanetary warming has significantly accelerated over the past 10 years, with temperatures rising at a higher rate since 2015 than in any previous decade on record, a new study showed.\u00a0\u00a0The Earth warmed around 0.35 degrees Celsius in the decade to 2025, compared to just under 0.2C per decade on average between 1970 and 2015, according to a paper published on Friday in the scientific journal Geophysical Research Letters. This is the first statistically significant evidence of an acceleration of global warming, the authors said.\u00a0 The past three years have been the hottest on record, compared to the average before the Industrial Revolution. In 2024, warming went past 1.5C, the lower limit set by the Paris Agreement. That target refers to temperature increases over 20 years, but breaching it for one year shows efforts to slow down climate change have been insufficient, the scientists who wrote the new paper said. \u2026 \u201d\u00a0 Read more from Bloomberg News<\/a>.<\/p>\n
