California to get break from storms, but not for long
“An extraordinarily active winter season across California has been full of moisture-laden storms that have helped completely erase persistent drought conditions in some areas due to epic amounts of rain and astonishingly high snowfall totals. The unrelenting storms have also had numerous negative consequences as well. That was evident this week when another atmospheric river generated extreme wind gusts in the San Francisco Bay Area, flooding rain in the Los Angeles basin and feet of heavy, wet snow across the highest elevations of the Sierra Nevada from Monday into Wednesday morning. The state will get a needed reprieve from storms for a brief period of time, but AccuWeather meteorologists are calling for a return of stormy conditions by next week. … ” Read more from AccuWeather.
The sog slog continues: Forecast calls for even more rain through March
“Californians shouldn’t put the rain gear away quite yet. March is expected to continue roaring like a lion beyond mid-month. Models are pointing to another potential atmospheric river in the first half of next week, forecasters say, the 12th of California’s wet season. An upper-level low-pressure system in the Gulf of Alaska is expected to move over the West Coast, and there’s a 60% chance that a plume of atmospheric river moisture could affect the California coast, the National Weather Service said. The six- to 10-day precipitation outlook issued by the National Oceanic and Atmospheric Administration on Wednesday shows well above normal precipitation for most of the state, with a 70% chance that precipitation will be above normal in the central portion of California. … ” Read more from the LA Times.
NOAA Spring Outlook: California drought cut by half with more relief to come
“Significant flooding is ongoing in the western U.S., especially in California, following another series of strong Pacific storms that battered the region and piled on to an already historic snowpack. According to NOAA’s U.S. Spring Outlook, the abnormally wet winter will further improve drought across much of the western U.S. as the snowpack melts in the coming months. Winter precipitation, combined with recent storms, wiped out exceptional and extreme drought in California for the first time since 2020, and is expected to further improve drought conditions this spring. NOAA’s U.S. Spring Outlook highlights temperature, precipitation, drought and flood predictions for April through June to help the nation prepare for potential weather and climate threats to lives and livelihoods. … ” Continue reading at NOAA.
What California’s excessive snow, rain mean for state’s reservoirs
“A series of atmospheric river events with heavy rain and snow have caused California water regulators to open flood gates on water storage facilities, but the uncertainty of when Mother Nature’s faucet will shut off has experts weighing the advantages and disadvantages of letting the precious resource run free. During average years, regulators say they work on keeping water levels high into the summer, but as mountains of heavy snow melt – literally – agencies are challenged with deciding how much water to store and what to allow to escape as part of flood control. Some mountain passes are approaching record territory, with the UC Berkeley Central Sierra Snow Lab reporting 668″ of fresh powder – a figure that is just shy of being the second-snowiest season on record – all while the state’s snowpack sits at a stage greater than 200 percent of average. … ” Read more from Fox Weather.
Scientists: Largest US reservoirs moving in right direction
“Parts of California are under water, the Rocky Mountains are bracing for more snow, flood warnings are in place in Nevada, and water is being released from some Arizona reservoirs to make room for an expected bountiful spring runoff. All the moisture has helped alleviate dry conditions in many parts of the western U.S. Even major reservoirs on the Colorado River are trending in the right direction. But climate experts caution that the favorable drought maps represent only a blip on the radar as the long-term effects of a stubborn drought persist. … ” Read more from ABC News.
Is the Western drought finally ending? That depends on where you look
Dan McEvoy writes, “After three years of extreme drought, the Western U.S. is finally getting a break. Mountain ranges are covered in deep snow, and water reservoirs in many areas are filling up following a series of atmospheric rivers that brought record rain and snowfall to large parts of the region. Many people are looking at the snow and water levels and asking: Is the drought finally over? There is a lot of nuance to the answer. Where you are in the West and how you define “drought” make a difference. As a drought and water researcher at the Desert Research Institute’s Western Regional Climate Center, here’s what I’m seeing. The winter of 2023 has made a big dent in improving the drought and potentially eliminating the water shortage problems of the last few summers. … ” Continue reading at The Conversation.
California deals with surging rivers, sliding rocks and flooded towns as storm passes
“Surging rivers. Sliding rocks. Flooded towns. The 11th atmospheric river storm of the season left a trail of soggy misery in California as it broke decades-old rainfall records and breached levees this week. In the Tulare County city of Porterville, residents on both sides of the Tule River were ordered to evacuate Wednesday morning as levels rose at Lake Success, sending water running over the spillway at Schafer Dam. “Right now the dam is in good working order — there’s no threat to the structure of the dam — but we have significant water coming off of the spillway,” said Carrie Monteiro, a spokeswoman for the Tulare County Emergency Operations Center. … ” Read more from the LA Times.
CDFW using winter storms to help increase survival of hatchery released chinook salmon
“Anticipating good conditions for the survival of hatchery-produced Chinook salmon throughout the Sacramento River and tributaries, the California Department of Fish and Wildlife (CDFW) will release both spring and fall-run Chinook during the historic rain and snowfall the state is experiencing. Several releases have already happened, and others are planned over the next few weeks to utilize good in-river habitat conditions for these young salmon. On Feb. 23, with a series of late-winter storms building, CDFW staff released approximately 1.1 million fall-run Chinook salmon fry into the American River at the Nimbus Fish Hatchery in Sacramento County. These Chinook salmon are part of a pilot study testing new genetic based tagging techniques that if successful, will allow more flexibility in fish release strategies to take advantage of natural high flow events in the future. … ” Read more from the Department of Fish & Wildlife.
Stunning viral video shows California farmers launching truck into levee to stop flooding
“A viral video that circulated among California farmers this week, showing two pricey pickup trucks sacrificed to plug a hole in a levee, reveals the drastic measures that some in the agricultural community are taking to protect fields from flooding. The recent storms, amid a historically wet winter, have caused rivers and streams to rise and sometimes spill their banks, threatening farmland in many parts of the state, including the highly productive southern San Joaquin Valley. … In the video shared Tuesday on Twitter by sixth-generation farmer Cannon Michael, who runs Bowles Farming Co. in the Los Banos area, a man puts his Chevy Silverado in drive, quickly exits the pickup and allows the truck to run into water that has breached an earthen levee — an effort to halt the flooding of a pistachio orchard. Another truck is already in the breach, helping stem the flow of water into the field. … ” Read the full story at the San Francisco Chronicle. | Read via MSN News. | View twitter video
Almond update: grower’s positive experience with groundwater recharge
“In working with the Turlock Irrigation District (TID), grower Eric Spycher’s groundwater recharge efforts are proving successful. He explained the process in a recent episode of the Almond Journey Podcast from the Almond Board of California. In the first year of the collaborative project, there were marked improvements to groundwater levels in local wells. Farming primarily in Delhi soils, Spycher said it made his operation a good fit for the project. “We put out I believe it was 14 inches per acre. So, over an acre-foot on the parcel that we irrigated. It was a 40-acre parcel and I think we only did about 10 or 15 acres of it because of the time it took to get the water to spread out,” said Spycher. “That’s one irrigation. Typically, a flood irrigation for me would have been three to four inches of water in the past. So this ground was so dry, even with all the rain, that it took quite a while to get the water to move across it.” … ” Read more from Ag Net West.
Calif. strawberry fields devastated by flooding
“The winter of 2022-23 has been devastating for California’s strawberry industry. After storms in December and January caused over $200 million in crop damage from wind, rain and floods, damage from recent flooding from the Pajaro and Salinas rivers in Monterey County has caused hundreds of millions of dollars more in losses, the California Strawberry Commission reports. The latest disaster comes as farmers had borrowed money to prepare the fields and were weeks away from beginning to harvest, said Rick Tomlinson, the commission’s president.

Sustainable Water Investment Summit takeaways: Water rights, scarcity and opportunities
“Last week, leaders from a range of industries convened for two days in Los Angeles for Brownstein and WestWater’s inaugural Sustainable Water Investment Summit. The summit featured Antonio Villaraigosa, former mayor of Los Angeles and current infrastructure advisor for the state of California. Tasked by Gov. Gavin Newsom to collaborate across local, state and federal levels to identify priority projects to address California’s pressing infrastructure needs and serve as a liaison with federal leaders to maximize California’s access to federal funding across all regions of the state, Villaraigosa appears keenly aware of both the unprecedented challenges (including regulatory bottlenecks) that the state faces and unique opportunities presented by federal infrastructure funding. … ” Read more from Brownstein via JD Supra.
Brownstein scores big win in case affecting all water users in California
“Although water reuse is a high priority for California, the considerations a city or other water supplier must contend with in navigating the development of new water supplies are both manifold and highly complex. A recent Brownstein win at California’s Second District Court of Appeal acknowledges the irrefutable importance of supplies like recycled water without sacrificing local autonomy or overburdening state agencies. The Second District Court of Appeal decision establishes that the State Water Resources Control Board (SWRCB) has broad discretion to investigate, or not, allegations of waste or unreasonable use, likely stemming an influx of lawsuits seeking to force the SWRCB to investigate every user and use of water in California. Brownstein prevailed on all three issues on appeal in a major case interpreting California’s reasonable use doctrine (Article X, section 2 of the California Constitution), which governs all uses of water resources in California. … ” Continue reading at Brownstein.
The past, present, and future of USGS streamgages
“In the late 1800s, John Wesley Powell, second Director of the U.S. Geological Survey, had a vision for the Western United States. After exploring the West, Powell recognized that the availability of water was key to the settlement of the region. Powell proposed to inventory all streams in the West to evaluate the potential for irrigation in the region. The essential first step in this process was to gage the flow of those streams. A few cities in the Eastern United States had already begun using streamgages, as early as the 1870s, to collect data needed for the design of their water supply systems. Their methods generally involved constructing channels and dams to enable accurate gaging; however, these methods were not feasible in the West. In January 1889, the first USGS streamgage was established along the Rio Grande near Embudo, New Mexico. The Rio Grande at Embudo streamgage was developed to handle the unique challenges of the Rio Grande: shallow, fast-moving water and soft, mobile channel beds. The equipment and techniques developed at the Embudo site became the foundation of USGS streamgaging methods. … ” Continue reading at the USGS.

In California, the preservation of our state ecology is pitted against our water needs
Jun Park, a candidate for a master of social work at the University of Southern California, writes, “The Sacramento-San Joaquin Delta has emerged as the heart of our state’s vast water system, providing fresh water to two-thirds of the state’s population and six million acres of farmland. In January of 2023, Downtown Sacramento received 7.54 inches of rainfall, nearly doubling its 30-year average (3.86 inches). The record precipitation induced disastrous flooding, accelerating runoff to the Pacific Ocean. Despite having a comprehensive system of natural reserves and human ingenuity, conservationists estimated that nearly 95% of the received rainfall in California was diverted to the Pacific Ocean. The wanton runoff ignited bipartisan outrage, driving nearly a dozen legislators hailing from the drought-stricken Central Valley to call for an increase in the amount of water captured in the State Water Project’s aqueducts. Although the runoff can be interpreted as an egregious failure of bureaucracy, water pumping restrictions are informed by environmental regulations that preserve the Delta’s ecological integrity. … ” Continue reading at the Sacramento Bee.
DeSantis, Newsom, and the algae apocalypse
Edward Ring, a senior fellow of the Center for American Greatness, writes, “It would not be surprising if the final candidates for president in November 2024 were Joe Biden and Donald Trump. But if a younger generation of candidates prevails in their respective primaries, an equally unsurprising outcome would be Gavin Newsom pitted against Ron DeSantis. While purists on both sides may find the California Democrat and the Florida Republican to be far from perfect embodiments of their ideals, a contest between these two governors would nonetheless be a contest between two very different visions for the future of America insofar as they govern two big states that diverge on almost every policy of consequence. The prevailing perception of a hypothetical race between Newsom and DeSantis focuses on cultural issues, with both of them claiming their state is a beacon of freedom. But a comparison of equal consequence could be based on their response to environmental challenges. … ” Read more from American Greatness.
Amid solar energy rush, let’s protect our farmlands
Mike Wade, Executive Director of the California Farm Water Coalition, writes, “Excellent soils and a Mediterranean climate make California one of the most productive agricultural centers in the world, allowing our state to produce two-thirds of the nation’s fruits and nuts, and one-third of its vegetables. Not making the best use of this unique agricultural resource would be a big mistake. Yet, the U.S Department of Agriculture says California lost 1 million acres of irrigated farmland between 1997 and 2017. After years of failures to build new state water storage infrastructure, another 1.2 million acres were fallowed in 2020 and 2021 alone due to drought and water shortages, according to the University of California, Merced. For generations, much of the lost farmland has been attributed to urban or suburban development, a reality that will continue as the state’s population keeps growing. Now there is a significant new threat to farmlands: California’s desire to build a massive amount of new solar facilities. … ” Read more from Ag Alert.

U.S. public water supply is a local source of phosphorus pollution
“In the United States, public water systems are sometimes dosed with phosphate to reduce copper levels and lead pipe corrosion. This practice can help avert humanitarian disasters like the Flint water crisis, but because phosphorus can contribute to eutrophication, it could harm local aquatic ecosystems. For example, phosphorus that enters the environment when pipes leak or people water their lawns may find its way into rivers, lakes, and groundwater. Exactly how much phosphorus enters the environment from the public water supply, though, is unknown, making it difficult to address this source of pollution. Flint et al. estimate for the first time how much phosphorus enters the environment from the U.S. public water supply. Using data from 2015, the team analyzed phosphate dosing concentrations, data from public water system facilities, the volume of water supplied by these facilities, and estimates of how much water is lost because of leakage and outdoor water use. … ” Read more from EOS.
PFAS rule sets up sprawling legal war
“EPA’s historic move to regulate “forever chemicals” in drinking water has set the stage for a multi-pronged courtroom slugfest among the agency, water utilities that must comply with the rule and multinational conglomerates that have flooded the environment with the toxicants linked to a long list of health problems, including cancer. Although lawsuits cannot be filed until EPA finalizes its PFAS proposal, interested parties will spend the coming months filling the regulatory docket with comments that will eventually inform the final rule or shape opponents’ future legal challenges against the agency — and one another. Case law on the topic is limited: EPA’s proposal marks the agency’s first enforceable standard of its kind for PFAS and its first effort to regulate a drinking water contaminant in over 25 years. … ” Read more from E&E News.

As 1.5 degrees looms, scientists see growing risk of runaway warming, urgent need to slash emissions
“As the planet rapidly approaches 1.5 degrees C of warming, scientists warn that rising temperatures are degrading the Earth’s ability to soak up carbon dioxide, threatening to further exacerbate climate change. To keep warming in check, they stress, countries must make steep cuts to emissions in the next few years. Research highlighted in Hot Science, a project of the Bezos Earth Fund and World Resources Institute, underscores the urgent need to draw down emissions, which hit a record high last year as the global economy recovered from the pandemic slowdown. Ocean warming also hit a new high in 2022, with scientists warning that the “global long-term warming trend is so steady and robust that annual records continue to be set with each new year.” … ” Read more from Yale e360.
