Harder pushes back on Newsom’s embrace of Delta tunnel
“Gov. Gavin Newsom’s recent embrace of a once dead-on-arrival proposal to move water from Northern California to the San Joaquin Valley and further points south via tunnel underneath the Sacramento-San Joaquin Delta is coming under fire. This time, however, opposition is mounting from a fellow Democrats on Capitol Hill who have cast the project as a water grab to benefit communities and farms south of the Delta. Driving the news: Thursday, Rep. Josh Harder (D-Tracy) announced his re-introduction of the Stop the Delta Tunnel Act, aiming to block the drive to build a massive tunnel to convey water around the environmentally-sensitive Delta. … ” Read more from the San Joaquin Valley Sun.
Reservoirs rise, but groundwater woes remain
“From late December 2022 into January 2023, a series of damaging storms delivered a tremendous amount of precipitation to California, helping to replenish mountain snowpack and reservoirs. Still, the abundance of water is unlikely to reverse the region’s decades-long decline in groundwater. The images above and below show the two largest reservoirs in California—Shasta Lake and Lake Oroville—before and after the winter storms. They were acquired in November 2022 (left) and in late January 2023 (right) by the Operational Land Imager (OLI) on Landsat 8 and the OLI-2 on Landsat 9. … ” Read more and view picture at NASA’s Earth Observatory.
Dramatic photos show Lake Oroville’s rise after epic storms
“Lake Oroville, a key component of California’s water supply, looks noticeably fuller after a series of January storms. The atmospheric rivers dumped trillions of gallons of moisture on the state, spurring widespread flooding and destruction but also providing a healthy boost to snowpack and drought-sapped reservoirs. Lake Oroville, the largest reservoir on the State Water Project, was at 68% of its capacity on Friday — up from 28% just two months prior, according to state data. … ” Read more and view pictures at the LA Times.

A new strategy for western states to adapt to long-term drought: Customized water pricing
“Even after heavy snow and rainfall in January, western states still face an ongoing drought risk that is likely to grow worse thanks to climate change. A whopping snowpack is good news, but it doesn’t reduce the need for long-term planning. … Basic economics teaches us that a higher price for water would encourage conservation. Up until now, however, concerns about harming low-income households have limited discussions about raising water prices to reduce demand. We know that it’s hard to pay more for essential goods such as food, energy and water, especially for lower-income households. Rather than raising everyone’s water prices, we propose a customized approach that lets individual consumers decide whether to pay higher prices. … ” Read more from The Conversation.
Salt and smelt: Assessing the effect of the Fall x2 outflow action on endangered Delta smelt
“Recent research has revealed that the habitat needs of endangered delta smelt (Hypomesus transpacificus) may be more complex than what is accounted for in current management efforts. One ongoing effort intended to aid delta smelt recovery is the “Fall X2 Outflow Action,” which is a strategic increase in outflow into the Sacramento-San Joaquin Delta to improve habitat for delta smelt during a key life history period when adult fish are maturing prior to their spawning migration. This increase in outflow is thought to improve the quantity and quality of delta smelt habitat by maintaining flows to sustain a low-salinity zone, in this case, a region with an average salinity less than 2 parts per thousand (a location referred to as X2). The position of X2 depends on the previous water year. Following a wet year or normal year, X2 is located approximately 74 kilometers to 81 kilometers upstream of the Golden Gate Bridge. However, the findings of a recent study suggest that managing delta smelt habitat by adjusting the position of X2 may not be as effective as previously thought. … ” Continue reading at FishBio.
Green sturgeon in California: Hidden lives revealed from long-term tracking
“You gotta respect fishes that have been around since the dinosaurs, such as the 27 described sturgeon species. Unfortunately, the majority of these fishes currently face a high risk of extinction. Extinctions happen to these gentle giants. The Chinese Paddlefish went extinct following a long-term decline – finished off by the Three Gorges Dam (Zhang et al. 2020). California has two sturgeon species: White Sturgeon and Green Sturgeon. Recently, Schreier et al. 2022 published a blog on the status of White Sturgeon in California focused on impacts from a mass die off during a red tide event in the summer of 2022. Here we focus on the southern distinct population segment (DPS) of Green Sturgeon (Fig. 1), a federally ‘threatened’ species under the US Endangered Species Act. Green Sturgeon are fully anadromous and live primarily in the ocean as adults, but spawn in freshwater rivers in the spring. High-quality habitat is essential for the life-history of native fishes, especially in California (Sass et al. 2017, Hause et al. 2022). Yet despite their large size and historical importance to many communities, there is still much we don’t know about Green Sturgeon biology in California. … ” Read more from the California Water Blog.
Why historic storms are ‘both a blessing and a curse’ for California’s fire season
“A series of torrential storms kicked off 2023, replenishing a parched landscape and improving drought conditions across California. Reservoirs are filling back up to normal levels and lush, green grasses are blanketing hillsides. … Data shows that rainy, wet winters in California typically accompany fewer acres burned in wildfires come fire season. Woody vegetation, in high-elevation forests and chaparral landscapes, can hold onto this moisture through the summer, especially if it’s supplemented by spring rains. The historic precipitation brings hope for a mild fire season, but the now-abundant grasses also serve as potent wildfire fuel, leaving uncertainty about how wildfires will unfold in the coming months. … ” Read more from the San Francisco Chronicle. | Read similar story from The Guardian.

How California can solve the Colorado water deficit
Edward Ring, co-founder of the California Policy Center and the author of The Abundance Choice: Our Fight for More Water in California, writes, “When the Hoover Dam was completed in 1935 it was the largest dam in the world, creating what was to become the largest reservoir in the world, Lake Mead. It took six years to fill, but at capacity Lake Mead held 28 million acre-feet (MAF) of water. Mead’s upstream counterpart, Lake Powell, created by the Glen Canyon Dam and completed in 1963, delivered an additional 25 MAF of storage capacity. Access to the water stored in these giant reservoirs made possible the growth of cities and agriculture from the California coast all the way to Tucson in southeast Arizona. Las Vegas and Phoenix would not exist if it weren’t for these dams, nor would nearly 500,000 acres of rich irrigated farmland in California’s Imperial Valley along the border with Mexico. … ” Read the full commentary at the National Review.
Who will save (not stop) the rain?
Winnie Comstock-Carlson, President and Publisher of Comstock’s, writes, “Our beloved Capital Region has been literally awash with rain, snow, flooding and downed trees, and I’m sure many of us think that California’s persistent drought has at last been rinsed away. After all, we’ve received huge amounts of snow in the Sierra, which will thaw and flow westward to fill our reservoirs, basins and valleys as it makes its way to sea. Add to that the atmospheric rivers of rain that have been pouring into our towns, overflowing our riverbanks, curbs, basements and canals, we’re tempted to assume that our state is no longer destined to be a desert. But that’s probably not going to be the case. … ” Read more from Comstock’s.

Klamath countdown: Researchers hustle before largest dam-removal project begins
“Next year will be the big year. By the end of 2024 the Lower Klamath River will run free for the first time in a century, enabling fish like salmon and steelhead to reclaim 400 miles of river habitat in California and Oregon. The removal of four dams on the river — the largest dam-removal and river-restoration project to date — got the official go-ahead late last year after two decades of work from the region’s Tribes and other advocates. But before next year’s much-anticipated demolitions begin, a lot remains to be done. The smallest of the four dams, Copco 2, will come down in 2023, and crews will improve roads and bridges, move a municipal water line, and build a new fish hatchery. … ” Continue reading at The Revelator.

Storms renew Point Reyes ranching water contamination concerns
“The recent storms in the region have revived concerns about agricultural runoff in the Point Reyes National Seashore contaminating creeks and beaches, including those where elephant seals are breeding. After the series of powerful storms last month, some visitors sent the National Park Service photos of brown water running down hills from two dairy ranches near Kehoe Creek and at Drakes Beach, where elephant seals were breeding and raising their pups. Park officials said inspections at the two ranches — Kehoe Ranch and B Ranch — found that the runoff was not pure liquid manure as some visitors had suggested. Melanie Gunn, a park official, said the runoff from the ranches included residue from feed areas, mud and general agricultural runoff that might contain dispersed manure. “There is runoff and it may be brown and dark and people may be assuming it’s liquid manure,” Gunn said. … ” Read more from the Marin Independent Journal.

Storm aftermath: When trees fall in the forest
“Plenty of trees are falling in the forest this winter and Monterey County officials are hearing all about it. January’s storms brought high winds and persistent, soil-saturating rains — perfect conditions for knocking over even the healthiest of trees. Mayra Tostado, a PG&E spokeswoman, said in an email that PG&E responded to over 150 power outages in January in the Monterey area that were caused by fallen vegetation. PG&E does try to prevent tree-caused power outages. Twice a year in “High Fire Threat Districts,” including Monterey County, they inspect and mitigate trees deemed at risk to fall into PG&E facilities. They’ve also conducted “fuel reduction projects” over the past five years, trimming and removing defective and hazardous trees and trees in densely vegetated areas. … ” Read more from the Monterey Herald.
What to know about one-day per week watering in Ventura County
“Ventura County residents limited to one-day-a-week watering may soon get some relief.

Wall Street sees profits in dropping Colorado River levels
“As Wyoming and other Colorado River Basin states grapple with ways to keep a river more than 40 million people, agriculture and industry depend on flowing, Wall Street is tapping water scarcity to deliver steep profits. Gary Wockner, director of the group Save the Colorado, said hedge funds and other investors have acquired key parcels of land with water rights. In the early 2000s, Wockner pointed out, you could buy Colorado River water for about $8,000 dollars per acre foot. Last year, an acre foot was selling for $80,000 dollars. “Over a 20-year period, it went up 1,000% in price,” Wockner noted. “That’s 50% per year, and that’s a pretty good profit, no matter what you’re investing in. And this is going on throughout the southwest United States.” … ” Read more from the Public News Service.
Radio: How will the West adapt as the Colorado River runs dry?
Western states depend on the Colorado River for water. They’re up against a reality that’s been a long time coming: “It’s not like the river changed overnight. The river has been changing over the last 20 years at least,” Jennifer Pitt says. “But we were buffered from the impacts of the change on water in the water supply by draining reservoirs.” States have been drawing down so much water, that reservoirs are approaching the point where it may be impossible to pull more out of them. It’s a scenario called deadpool. Recently, six Western states did come up with a proposal for how to cut water. But one state wouldn’t sign on: California. Today, On Point: We’re going to talk about why, and what’s at stake.” Listen at WBUR.
Long term ‘isn’t looking good’ for America’s largest reservoirs, Mead and Powell, says water manager
“Lakes Powell and Mead, designed to water the West during drought, are still at critical levels despite a “good” snow season. The government demands further cuts from states in the Colorado River Basin as current usage is not sustainable. While California’s reservoirs may have a water supply bonanza of snowfall this winter, Lakes Powell and Mead have little to celebrate about. The atmospheric river storms that dumped twice the amount of winter snow in some areas of the Sierra Nevada Mountains have only resulted in near average snowpack for the Rockies which supply water to the Colorado River. And it is not enough, water managers say. … ” Read more from Fox Weather.

Acesulfame: sweetener reveals information about groundwater flows
“Acesulfame is a sugar-free sweetener, and because it cannot be metabolized in the human body, the sweetener ends up in wastewater after consumption and remains largely intact even in sewage treatment plants. According to a new study, the persistence of the sweetener varies with temperature, just as the concentration of the sweetener in wastewater varies with the seasons. The environmental geosciences team investigated how seasonal fluctuations in groundwater flows can be used to trace groundwater flows. Because sweetener residues end up in drinking water, acesulfame serves as an indicator of the origin and composition of our drinking water. … ” Read more from Nature World News.
