How can California boost its water supply?
“Over and over again, drought launches California into a familiar scramble to provide enough water. Cities and towns call for conservation and brace for shortages. Growers fallow fields and ranchers sell cows. And thousands of people discover that they can’t squeeze another drop from their wells. So where can California get enough water to survive the latest dry stretch — and the next one, and the next? Can it pump more water from the salty Pacific Ocean? Treat waste flushed down toilets and washed down drains? Capture runoff that flows off streets into storm drains? Tow Antarctic icebergs to Los Angeles? Every time another drought rolls around, an array of suggestions rise to the surface. We take a look at the strategies that could work — along with the more outlandish ones — and the obstacles they face. … ” Read the full story at Cal Matters here: How can California boost its water supply?
San Francisco cuts deal with California water regulators to avoid severe restrictions
“Three of California’s biggest water suppliers, including the city of San Francisco, have reached a deal with the state that calls for reducing their immense consumption of river water but not as much as the state had initially demanded. The compromise, announced Thursday, is the latest breakthrough in a years-long effort by state regulators to protect flows in California’s once-grand but increasingly overdrawn rivers. The toll on the waterways, where as much as 90% of the water is pumped to cities and farms, has been exacerbated by drought, leaving fabled runs of salmon and other plants and animals at risk of perishing. Under the new agreement, the San Francisco Public Utilities Commission joins two Central Valley water agencies, the Turlock and Modesto irrigation districts, in committing to scale back draws and restore wildlife habitat in the Tuolumne River, one of the state’s most depleted rivers. … ” Read more from the San Francisco Chronicle here: San Francisco cuts deal with California water regulators to avoid severe restrictions

Proposed Central Valley dam likely to move forward after judge’s ruling
“Both sides of a controversial proposed Central Valley dam hailed a Nov. 3 court ruling kicking back the project’s environmental documents as a success. A Stanislaus County Superior Court Judge ruled there was insufficient information about a road relocation that is part of the proposed Del Puerto Canyon Reservoir project, which would sit just above the town of Patterson in the Diablo Range on the west side of the San Joaquin Valley. More definitive information on the proposed realignment of Del Puerto Canyon Road will have to be provided in the Environmental Impact Report by project proponents, the Del Puerto Water District and the San Joaquin River Exchange Contractor Authority. But that’s the only redo required. … ” Read more from SJV Water here: Proposed Central Valley dam likely to move forward after judge’s ruling
Fortifying B.F. Sisk Dam and San Luis Reservoir against the power of an earthquake
“Earthquakes are a fact of life in California, and at the B.F. Sisk Dam and San Luis Reservoir work is underway to ensure the continued viability and durability of the key resources, even when Mother Nature decides to shake things up. A major seismic upgrade, the largest project of that scale that has occurred at the site since its construction in 1967, received a $100 million investment earlier this year from the Bipartisan Infrastructure Law. It is Reclamation’s largest dam safety project under the 1978 Safety of Dams Act. Situated amid the rolling slopes of the Diablo Range in Merced County, Sisk Dam and San Luis Reservoir are an important link in the storage and conveyance chain of the Central Valley Project and State Water Project. With a storage capacity of more than 2 million acre-feet, the reservoir is the largest off-stream storage facility in the United States, providing water for farms, wildlife refuges, and millions of Californians. … ” Read more from the Bureau of Reclamation here: Fortifying B.F.

California was in exceptional drought a year ago. After recent rains, where are we now?
“California’s drought situation is looking better this year compared with the same time last year. In November 2021, more than 80% of California was in extreme or worse drought, compared with about 43% this year, U.S. Drought Monitor data shows. The data is updated weekly and shows drought conditions across the country. Aside from the San Joaquin Valley, exceptional drought conditions have been stomped out across the majority of the state. This means East Bay and North Bay cities like Oakland, Napa and Walnut Creek are finally out of this most severe drought designation. … ” Read more from the San Francisco Chronicle here: California was in exceptional drought a year ago.

California should change fishing rules after hundreds of sturgeon die, scientists say
“A dozen independent fish scientists are calling for urgent changes to sport fishing rules to save California’s largest freshwater fish after an unprecedented red tide this summer left hundreds of them dead in the estuary on Sacramento’s doorstep. The fish is the white sturgeon — an ancient species native to the West Coast. The largest freshwater species in North America, they can grow 15 to 20 feet long, weigh a ton and live for nearly a century. Some of these behemoths migrate from the Pacific Ocean up the Sacramento River through California’s capital city each year. But this summer’s deadly red tide has independent scientists worried about the future of this species. … ” Read more from the Sacramento Bee here: California should change fishing rules after hundreds of sturgeon die, scientists say
They defied California and drained an important salmon stream. Their fine: $50 per farmer
“For eight straight days this summer, farmers in far Northern California drained almost all of the water out of a river in defiance of the state’s drought regulations. The move infuriated environmentalists and salmon-dependent Native American tribes downstream. California now knows the cost of the farmers’ blatant defiance: Less than $50 per farmer. It’s the latest example of California’s lax water-use enforcement process — problems that were first exposed in a sweeping Sacramento Bee investigation published online last week. … ” Read more from the Sacramento Bee here: They defied California and drained an important salmon stream.

The Delta: Carbon credits versus the Big Gulp
“Twitchell Island, Sacramento County, California – Steve Deverel gazes out over a levee on the San Joaquin River to a buoy where half a dozen sea lions are barking. It’s a loud reminder that even here, 50 miles inland, some of California’s most productive farmland lies perilously close to the Pacific Ocean. At any moment, a weak spot in the more than 1,000 miles of earthen levees protecting islands in the Sacramento-San Joaquin River Delta could unleash a salty deluge, threatening not just crops, but the drinking water for as many as 27 million Californians. Deverel, a Davis-based hydrologist, refers to this threat as “The Big Gulp,” a breach that would suck in tens of billions of gallons of river water, drawing ocean water in its wake. All it would take is some heavy rain, a moderate earthquake, or even hard-working gophers tunneling through earthen barriers first built in the late 1800s. It wouldn’t be the first time such a disaster happened. Deverel now hopes to save the Delta by flooding it before the Pacific can. And he wants to pay for it with carbon credits. … ” Read more from the Public News Service here: The Delta: Carbon credits versus the Big Gulp
Efforts to protect groundwater are tested by drought
“Balancing the state’s groundwater supplies for a sustainable future may not be easy due to severe drought and ongoing economic challenges facing farmers. “We’ve got the lowest prices and highest production costs and the least-reliable water supply that we’ve had since I’ve been farming,” said Bill Diedrich of Firebaugh, who farms row crops and permanent crops on the west side in Madera and Fresno counties. “We’ve had one or the other but not all three at the same time.” Diedrich, who relies on groundwater for irrigating farmland in Madera County and surface water for ground in Fresno County, said farming at this time “is very difficult.” He said the 2014 Sustainable Groundwater Management Act, which tasks local agencies to balance groundwater supplies in affected basins by 2040 and 2042, means farmland must come out of production. … ” Read more from Ag Alert here: Efforts to protect groundwater are tested by drought.
They used to call California ocean desalination a disaster. But water crisis brings new look
“For decades, environmentalists have decried ocean desalination as an ecological disaster, while cost-savvy water managers have thumbed their noses at desal’s lofty price tag. But as the American Southwest barrels into a new era of extreme heat, drought and aridification, officials and conservationists are giving new consideration to the process of converting saltwater into drinking water, and the role it may play in California’s future. Although desalination requires significant energy, California’s current extended drought has revived interest in the technology. Experts are already experimenting with new concepts such as mobile desalination units and floating buoys, and at least four major plants will soon be operational along the state’s coastline. … ” Read more from the LA Times here: They used to call California ocean desalination a disaster.

Congress members seek to open up Hetch Hetchy to water recreation
“A move is afoot in Congress to increase the annual “rent” the City of San Francisco pays for the privilege of flooding Hetch Hetchy Valley in Yosemite National Park from $30,000 to at least $2 million. The bill by Rep. Connie Conway, who represents much of the southern San Joaquin Valley, is designed to require the City of San Francisco to not only pay fair market for renting the only land ever flooded for a reservoir in a national park, but also to force the city to comply to terms they agreed to in the 1913 Raker Act. Among those terms was allowing recreational uses such as non-motorized watercraft, camping and picnicking at Hetchy Hetchy and Lake Eleanor in exchange for flooding the valley. Conway’s bill also would allow swimming. … ” Read more from the Turlock Journal here: Congress members seek to open up Hetch Hetchy to water recreation

How climate change altered a longstanding Central Valley water reform
Congressman Jared Huffman and former Congressman George Miller write, “Thirty years ago, President George H.W. Bush signed an ambitious California water reform known as the Central Valley Project Improvement Act, or the CVPIA. The bill responded to a drought, crashing salmon runs, threats to Central Valley wetlands and antiquated water policies. California is again suffering from drought and low fish counts. The CVPIA’s successes and failures provide lessons to help ensure a healthy environment and more reliable water supplies. It is time to take the next steps. The CVPIA dedicated water to salmon and created a restoration fund to support salmon rebuilding projects. Unfortunately, rather than rebounding, salmon populations have declined since the law was enacted. … ” Read more from Cal Matters here: How climate change altered a longstanding Central Valley water reform
Expand solar development in the desert, not San Joaquin Valley farms
Edward Ring, author and co-founder of the California Policy Center, writes, “Successfully coping with severe droughts in California and the Southwest requires tough choices, all of them expensive and none of them perfect. But taking millions of acres out of cultivation and replacing them with solar farms is not the answer. California produces over one-third of America’s vegetables and three quarters of the country’s fruits and nuts – more than half of which is grown in the San Joaquin Valley. According to the California Farmland Trust, the San Joaquin Basin contains the world’s largest patch of Class 1 soil, which is the best there is. Putting solar farms in more than a small fraction of this rich land will not only displace farming, but have a heat island impact in the enclosed valley. That would be unhealthy for the farms and people that remain, and could even change atmospheric conditions over a wide area, worsening the drought. … ” Read more from Cal Matters here: Expand solar development in the desert, not San Joaquin Valley farms
Del Puerto Canyon dam ruling was more than just a “minor setback,” advocate says
Doug Maner, an environmental advocate and retired Modesto criminal lawyer, writes, “On Halloween, Stanislaus County Judge John Mayne gave nature lovers a small gift. The judge sent the proposed Del Puerto Reservoir west of Patterson back to the drawing board by ruling that the proposed relocation of Del Puerto Canyon Road violates the California Environmental Quality Act because it did not provide a location, leaving it up to future planners to decide. This will require that the Del Puerto Water District prepare a supplement to its Environmental Impact Report. Unfortunately, claims relating to the environment — including harm to the downstream riparian habitat, scenic and social impacts, water and air quality, pollution caused by construction, and potential damage to wildlife — were adequately addressed in the EIR, according to the court. … ” Continue reading from the Modesto Bee here: Del Puerto Canyon dam ruling was more than just a “minor setback,” advocate says
Our farmers are conserving to help Colorado River
Tina Shields, water department manager for the Imperial Irrigation District, writes, “The Imperial Irrigation District, the largest irrigation district in the U.S., announced last month that it is prepared to undertake substantial water conservation measures from 2023 through 2026 as a part of California’s voluntary proposal to create 400,000 acre-feet in water savings per year to address drought impacts on the Colorado River. IID’s 250,000-acre-feet contribution accounts for more than 62% of California water agencies’ proposal to help prevent Lake Mead in Nevada and Lake Powell in Utah and Arizona from falling to critically low elevations that would threaten water deliveries and power production in the near term. The U.S. Bureau of Reclamation is working with stakeholders in seven states that depend on Colorado River water to develop longer-term operating guidelines to replace those expiring in 2025. The overall sustainability of the Colorado River is critical for IID as it enables a robust, year-round agricultural industry that grows food and fiber to sustain millions of people. … ” Read more from Ag Alert here: Our farmers are conserving to help Colorado River
The difference between farmers and water privateers
Carolee Krieger, Executive Director of the California Water Impact Network, writes, “Productive agriculture is essential to civilization, but water privateering – the seizure of public trust water for exorbitant private profit – is not. California’s water privateers often present themselves as farmers. But while they may use the water they’ve commandeered from state and federal water conveyance projects for industrial-scale agribusiness initiatives, they’re not farmers. They’re water brokers. If there’s money to be made in irrigating almonds or pistachios, they’ll do that. If there’s more money to be made by selling their allocated water to cities or other agribusiness operations, they’ll choose that option instead. It’s not about a devotion to agriculture – and certainly not about food security or land stewardship. It’s about maximum profit derived by gaming flawed water policies that favor the rich, the powerful and the few over the general public. … ” Continue reading at the California Water Impact Network here: The difference between farmers and water privateers

Eyes on the horizon: Deer Creek “Fire Flume” has potential to threaten Nevada City, Lake Wildwood and Cascade Shores – more than 7,400 residents
“Vicky Reeder never would have imagined the hyper-vigilance required to protect her life and property when she first moved from the Bay Area to her quiet forest home. In the seven years since moving to Nevada City, she can count seven close calls with human-caused fires, four of them started by nearby illegal camps. It’s a concern echoed by many living in Nevada County. “I think every year everyone has to hold their breath and cross their fingers that we’re not going to have a major fire,” Reeder said. Despite years of work on defensible space, the recent blaze was another reminder of the dangers posed by living in the Deer Creek watershed. CAL FIRE identifies Nevada City and the Deer Creek Watershed as a “High Priority Target Area” because of the “high structure loss potential” in its annual 2022 Strategic Fire Plan. … ” Read more from Yuba Net here: Eyes on the horizon: Deer Creek “Fire Flume” has potential to threaten Nevada City, Lake Wildwood and Cascade Shores – more than 7,400 residents
Santa Rosa looks to shore up strategy to keep Eel River water available for use
“PG&E has begun relinquishing its control of the Potter Valley Project. Concerned that this will reduce water supplies, Santa Rosa is exploring options. Mendocino County’s century old Potter Valley Project consists of two Eel River dams, a tunnel diverting some of the Eel into the East Fork of the Russian River, and an inoperable powerhouse in need of expensive repairs. Outgoing Santa Rosa council member Tom Schwedhelm said one thing is certain. “This is going be challenging,” Schwedhelm said. “It’s going to be years ahead of us, but we just need to be supported being on the same team because Santa Rosa, this isn’t our main source, but we are some of the big players in this.” ... ” Read more from Northern California Public Media here: Santa Rosa looks to shore up strategy to keep Eel River water available for use
Little fish, big splash: Coho salmon’s Mill Creek debut stuns conservationists
“Beneath the cool water of Mill Creek in the San Vicente Redwoods, silvery coho salmon have been spotted for the first time ever. Their appearance comes as a welcome surprise to conservations and ecologists, who returned to the creek in September to survey the site following the removal of the Mill Creek dam a year earlier. For over a century, the Mill Creek dam had segmented its namesake stream. Conservationists hoped removing the dam would allow steelhead trout to migrate upstream, reclaiming decades of lost habitat. Removing the dam would also free trapped sediment, which conservationists hoped could create spawning grounds for endangered coho salmon. Scientists identified 15 juvenile coho salmon at the base of Mill Creek, near its junction with San Vicente Creek, as well as 12 juvenile steelhead trout, including some upstream of the dam’s removal. … ” Read more from Lookout Santa Cruz here: Little fish, big splash: Coho salmon’s Mill Creek debut stuns conservationists
The future of the Peninsula’s water supply comes before two state boards next week
“Thursday, Nov. 17 is shaping up to be a momentous day for the future of the Monterey Peninsula’s water supply, as two major state boards – the California Coastal Commission and the California Public Utilities Commission – are set to weigh in on two separate projects that aim to add supply to the local portfolio. Arguably, the more weighty of the two hearings is the Coastal Commission’s, which is meeting for three days in the Board of Supervisors chambers in Salinas. In those chambers on Nov. 17, the commissioners will consider whether to grant a coastal development permit to California American Water for its proposed desalination project in Marina, which has been a lightning rod for controversy since first being proposed nearly a decade ago. Also on Nov. 17, the CPUC will consider approving a proposed decision for a water purchase agreement with Cal Am that would facilitate Pure Water Monterey’s expansion, which promises to provide an additional 2,250 acre-feet of recycled water annually to the regional water supply. … ” Read more from Monterey Weekly here: The future of the Peninsula’s water supply comes before two state boards next week
Mono Lake Committee looking toward the future State Water Board hearing
“With Mono Lake painfully low, talk has been frequent in recent months about the California State Water Resources Control Board’s future hearing on the matter. A hearing is required because the State Water Board itself set forth the requirement within the water rights of the Los Angeles Department of Water & Power (DWP). The Board stated it “will hold a hearing” if the lake did not rise to the mandated protection level by September 28, 2020. Unfortunately, the lake was only 30% of the way to the requirement on that date, and is even lower today. There’s no question that a hearing is in the future. So what will the hearing take a look at? And when will it happen? … ” Read more from the Mono Lake Committee here: Mono Lake Committee looking toward the future State Water Board hearing
Legacy of dust: How Owens Valley air pollution increases L.A. water bills
“Even as worsening drought and aridification force Los Angeles to end its overwhelming dependence on imported water, Angelenos may soon realize that weaning themselves off supplies from the rugged eastern Sierra Nevada doesn’t mean they will stop paying for the city’s long, complicated history there. That’s because, even if the city is able to make good on a pledge by Mayor Eric Garcetti to recycle 100% of its water by 2035 and increase its ability to capture storm water, Los Angeles will still have to pay millions of dollars to control the region’s hazardous dust pollution — an environmental consequence of L.A.’s draining of Owens Lake more than a century ago, as well as recent diversions that have lowered the level of Mono Lake farther north. Recently, the Los Angeles Department of Water and Power accused Owens Valley air pollution authorities of “regulatory overreach” when they fined the utility $21 million for ignoring an order to control dust on a 5-acre patch of dry lake bed. … ” Read more from the LA Times here: Legacy of dust: How Owens Valley air pollution increases L.A. water bills
Proposal to place solar panels over LA Aqueduct advances
“A proposal to place solar panels over the 370-mile Los Angeles Aqueduct in an attempt to reduce evaporation and add capacity for renewable energy for residents was approved by a council committee this week. Around one-tenth of the water in the aqueduct is lost from evaporation each year due to the length of travel for water to make it through the aqueduct, according to the office of Councilman Mitch O’Farrell, who introduced the motion. O’Farrell is the chair of the council’s Energy, Climate Change, Environmental Justice, and River committee. The aqueduct, which opened in 1913, provided nearly 40% of Los Angeles’ water supply each year between 2016 and 2019, but the city has lessened its reliance in recent years, according to the motion. … ” Read more from the Whittier Daily News here: Proposal to place solar panels over LA Aqueduct advances
Remaking the river that remade LA
“February 1938 was a wet month in Los Angeles. The ground, where it hadn’t been paved over, was saturated, which meant rain had nowhere to go except into the streets, canals and washes. On the 27th, a storm arrived. During the following days, the city received its second-highest 24-hour rainfall in history. Reservoirs overflowed, dams topped out and floodwaters careered down Pacoima Wash and Tujunga Wash toward the Los Angeles River. By the time the river peaked at Long Beach, its flow exceeded the Mississippi’s at St. Louis. “It was as if the Pacific had moved in to take back its ancient bed,” wrote Rupert Hughes in “City of Angels,” a 1941 novel that climaxes with the flood. In an instant, the Lankershim Bridge in North Hollywood collapsed, and five people were swept away. Sewer and gas lines ruptured; communications were cut; houses were lifted straight off their foundations and sank into the water. In all, 87 people died. ... ” Read more from the New York Times here: Remaking the river that remade LA
Lake Perris recreation industry says Newsom’s dam plan will sink it fast
“The Lake Perris Fairgrounds—one of America’s oldest public recreation destinations, just 70 miles from Los Angeles—is at the center of a bitter battle between the state and three entertainment businesses over the last phase of a retrofit to secure the neighboring Lake Perris Dam from the mother of all earthquakes. The owners of Perris Auto Speedway, the Latin music venue Toro Wapo Arena Event Center, and the Family A Fair Inc. concessions company, who lease the heavily-trafficked fairgrounds real estate, fear what will happen to the car races, rodeos and live music—and the people whose livelihoods depend on them—when construction resumes on yet another multi-year project at the nearby dam at Lake Perris. And while the locals and the state agree that upgrading the dam at Perris Lake is critical, the construction delays and disruptions are turning the nearby coveted Perris Fairgrounds into a legal no man’s land. … ” Read more from LA Magazine here: Lake Perris recreation industry says Newsom’s dam plan will sink it fast
Drought: Coachella Valley Water District to slash aquifer replenishment to reduce Colorado River water use
‘The Coachella Valley Water District’s board of directors voted Tuesday to cut back on groundwater replenishment over the next few years to reduce the district’s Colorado River water use amid historic drought conditions. Groundwater replenishment adds water to the local aquifer, which provides nearly all of the drinking water and domestic water sources in the Coachella Valley. Earlier this year, the Bureau of Reclamation called for the seven states that rely on the Colorado River — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — to use at least 15% less water next year from the drought-stricken river system, or between 2 million and 4 million acre-feet less. An acre-foot, about 326,000 gallons of water, is enough to supply about two households for a year. … ” Read more from the Desert Sun here: Drought: Coachella Valley Water District to slash aquifer replenishment to reduce Colorado River water use

Fallbrook, Rainbow would save on water bills by leaving San Diego wholesaler, report finds
“Farmers and other ratepayers in Fallbrook and Rainbow could see an average savings on their water bills of more than $20 a month by joining the Eastern Municipal Water District in Riverside County, according to a new report. However, the move may increase the cost of water for other San Diegans by more than $2 a month on average, according to the findings from the Local Agency Formation Commission, or LAFCO. The San Diego County Water Authority has been hostile to the idea of losing two of its 24 member agencies.

International water researcher highlights Colorado Basin’s “disappearing” groundwater
“For the past 20 years, two small satellites orbiting 250 miles above Earth have tracked a stark reality about the nation’s groundwater supplies, including across the parched Colorado River Basin: The water underground is vanishing. The NASA satellites began gathering data in 2002. Since then, Colorado River Basin groundwater has depleted much faster than water storage in the nation’s two largest reservoirs, according to research that underscores concerns about the increasingly tight water supply in the drought-stricken West. “We pay a tremendous amount of attention to the disappearance of surface water because we can see what’s happening with the reservoirs, Lake Powell and Mead,” hydrologist Jay Famiglietti said. Meanwhile, he warned, “groundwater is quietly disappearing.” … ” Read more from the Colorado Sun here: International water researcher highlights Colorado Basin’s “disappearing” groundwater
