Overview April 24, 2014 All Things Drought

Drought

Lake Oroville shows the effects of drought in July 2021.Drought— an extended period of limited or no precipitation— is a fact of life in California and the West, with water resources following boom-and-bust patterns.

No portion of the West has been immune to drought during the last century and drought occurs with much greater frequency in the West than in other regions of the country.

Most of the West experiences what is classified as severe to extreme drought more than 10 percent of the time, and a significant portion of the region experiences severe to extreme drought more than 15 percent of the time, according to the National Drought Mitigation Center.

Experts who have studied recent droughts say a drought occurs about once every 10 years somewhere in the United States. Droughts are believed to be the most costly of all natural disasters because of their widespread effects on agriculture and related industries, as well as on urbanized areas. One of those decennial droughts could cost as much as $38 billion, according to one estimate.

Because droughts cannot be prevented, experts are looking for better ways to forecast them and new approaches to managing droughts when they occur.

Heat, drought ravaging saguaros, new study finds

As saguaros across the Sonoran Desert suffer from the combined stresses of extreme heat and drought, researchers say these climate changes threaten the large saguaro forests we see across Southern Arizona and Northern Sonora. A new study finds that severely hot and dry weather dramatically increased saguaro mortality at two ends of the Sonoran Desert in 2020 and 2021 and that generally, the health of saguaros and other desert vegetation has declined significantly. The continued warming and drying threatens to irretrievably reduce the scale of and, in some cases, possibly eliminate the large saguaro forests, the researchers say.

News release: University researchers predict improved water yields after forest thinning

Thinning of forests, generally undertaken to reduce dangers from wildfire and restore the forest to a more natural state, also can create more mountain runoff to mitigate drought effects in the central Sierra Nevada region that relies on snowpack. In fact, researchers from the College of Agriculture, Biotechnology & Natural Resources at the University of Nevada, Reno found that the quantity of additional water produced by thinned forests can be so significant that it might provide further incentive for forest managers to undertake prescribed burning or tree-removal using heavy equipment and hand crews with chainsaws. Water yields from thinned forests can be increased by 8% to 14% during drought years, found the study undertaken by Adrian Harpold … and recently published in Water Resources Research.

Rapid snowmelt threatens US West water supply outlook

Rapid melts across the U.S. West have caused snowpack to disappear up to four weeks early in some areas — wreaking potential havoc on the region’s water supply, federal meteorologists warned Thursday. These conditions have particularly affected parts of Utah, Colorado and New Mexico, causing some basins to shift from above-average snowpack to “snow drought,” according to an update from the National Integrated Drought Information System (NIDIS). That transition occurred in under a month, with snow disappearing one to four weeks earlier than usual, the NIDIS updated stated. … As for the Colorado River Basin, the NIDIS update said that supply forecasts for this region declined in comparison to April 1 projections, presumably due to dry conditions and early, rapid snowmelt.

Nature Water study highlights global aridification, threat to agriculture

A long-term shift toward drier conditions is reshaping landscapes and livelihoods across the globe. Known as aridification, this gradual drying trend now affects 2.3 billion people and 40% of Earth’s land, with serious implications for agriculture and water systems—especially in the U.S. From California’s Central Valley to the Great Plains, often called the world’s breadbasket, farmers are facing tough decisions about what to plant, how to irrigate, and how to adapt to a future where water is no longer guaranteed. These findings appear in the Nature Water article “Increasing aridification calls for urgent global adaptive solutions and policy action,” led by Mississippi State University Associate Vice President and Professor Narcisa Pricope in collaboration with a team of international scientists.

Study: Fallowed agricultural lands dominate anthropogenic dust sources in California

Air pollution remains a major problem in many parts of California. … However, the contribution of anthropogenic dust from agricultural sources, among major pollutants in California’s semi-arid Central Valley, remains largely unclear. … We find that the Central Valley accounts for about 77% of total fallowed land areas in California, where they are associated with about 88% of major anthropogenic dust events. … We also find that the geographic coverage of these fallowed lands expanded between 2008 and 2022 with associated increasing anthropogenic dust activities. … Overall, our results have important implications for public health, including increased risk for Valley fever and for regional climates, such as increases in extreme precipitation and snowmelt over the Sierra Nevada. … (D)eposited dust can change snowmelt timing over the Sierra Nevada and substantially impact California’s vulnerability to water resources.

Torturing California’s almonds and pistachios to survive climate change

California is a national and global powerhouse when it comes to nuts. Recent data shows that the Golden State produces roughly 80% of the world’s almonds and 60% of the world’s pistachios. It’s a lot of nuts and a lot of money. But changing climate conditions are challenging nut growers. With warming winters and a propensity for drought, crops that did well 20 years ago might not make it 20 years from now. That’s where the plant geneticists and breeders at UC Davis’ Wolfskill Experimental Orchard come in. This week, Gabriela Glueck, KCRW’s Julia Child Reporting Fellow, takes us on a trip to the orchard to meet with two nut crop breeders who are trying to set up California almond and pistachio growers for success.

Friday Top of the Scroll: Utah Gov. Cox issues drought executive order, urges Utahns to conserve water

With Utah facing a drier year, Gov. Spencer Cox issued an executive order (Thursday) declaring a state of emergency in 17 counties due to drought conditions. … The governor’s executive order comes after the Drought Response Committee recently recommended he act due to drought conditions. … Cox’s emergency declaration also comes after he told reporters last week he was working on issuing one due to worsening drought conditions in southern Utah, which has seen a weak snowpack this winter. Though the governor said last week it’s been a “pretty normal year for most of the state,” there are some areas that are worse off than others. Currently, severe drought covers 42% of the state, and 4% is in extreme drought, according to the state’s website. This year, Utah’s snowpack peaked at 14.3 inches on March 23, which is equal to the state’s typical annual peak, according to state officials. However, southwestern Utah’s snowpack was only about 44% of normal.

Earth’s landmasses lost trillions of tons of water this century

Earth’s landmasses are holding onto a lot less water than they used to — and this loss is not just due to melting ice sheets. Terrestrial water storage, which includes water in underground aquifers, lakes, rivers and the tiny pore spaces within soil, declined by trillions of metric tons in the early 21st century, researchers report in the March 28 Science. This sharp decrease in freshwater stores is driven by rising temperatures on land and in the oceans, which in turn are linked to an increased global incidence of drought. And given the projected warming of the planet, this trend isn’t likely to change any time soon, say geophysicist Ki-Weon Seo of Seoul National University and colleagues.

California’s drought outlook will lead to more dust storms, poor air quality, study finds

The Climate Prediction Center’s recent dire drought outlook for California and the western United States has some more bad news: The dry, hot conditions will worsen air quality and introduce more dust and pollen allergens into the air. Meteorologists say Southern California will bear the brunt of the worst air quality and allergens, but the Central Valley may also be affected if wind patterns blow north. … The dry, hot conditions could lead to more dust storms — also called haboobs — in the region as well, meteorologists reported. Here’s what to know about how the dry, hot conditions will affect air quality in California.

See the latest California drought, wildfire forecasts ahead of summer

While cooler temperatures and more rain in March helped mitigate drought in some regions in California, drought conditions aren’t forecasted to improve for large swaths of the state in the coming months. A seasonal drought outlook by the Climate Prediction Center released on Thursday, April 17, valid through July 31, forecasts that Southern California and a central pocket of the state will see drought conditions persist with no improvement. It comes as a National Integrated Drought Information System update issued on April 10 reported that below-normal temperatures and higher-than-normal rainfall in March helped mitigate drought in the Central Valley and San Diego. Yet nearly 40% of California is in a drought, according to the latest available data from the U.S. Drought Monitor accessed on April 17.

Weather outlook improves following 2024’s heat-driven drought

According to the USDA Fruit and Tree Nuts Outlook (March 2025), 2024 brought historic heat to the United States, marking the warmest year in the contiguous U.S. since records began in 1895, according to NOAA’s National Centers for Environmental Information. While 2024 also ranked as the third wettest year overall, key agricultural states like California and Washington experienced a dangerous mix of summer dryness and extreme heat, significantly affecting fruit and tree nut production. … In California, southern regions were hit especially hard. By February 2025, the U.S. Drought Monitor reported moderate to extreme drought across the entire southeast interior of the state. In Northern California, drought was less severe. The Sacramento Valley saw a rapid shift from no drought in July 2024 to 100% of land classified as abnormally dry by October. … The San Joaquin Valley, largely drought-free through the summer, also saw worsening dryness by fall, with nearly all land in drought by February 2025—over 60% at moderate to severe levels.

Blog: Making recharge a “win-win” for landowners and groundwater agencies

The tenth anniversary of the Sustainable Groundwater Management Act (SGMA) last year put a spotlight on the challenges of implementing this landmark legislation. Agencies in both the San Joaquin and Sacramento Valleys scaled up efforts to replenish aquifers in recent years, but they still need ways to better harness the water received in wet years. Spreading water on privately owned land so it can penetrate the soil and refill below-ground aquifers — a process known as groundwater recharge — is one way to make the most of surplus water when it’s available. This can include methods such as spreading water on farmland or on land that’s set aside solely for recharge. Landowners may recharge using their own water and land, an irrigation district’s water on their private land, or their own water on an irrigation district’s land.

‘Really unusual’: New study shows why salmon vanished in NorCal

… Suzanne Rhoades and Cleo Woelfle-Hazard were monitoring salmon at two field sites hundreds of miles apart: the South Fork of the Eel River running through Humboldt and Mendocino counties and the Salmon Creek Watershed in western Sonoma County. But they realized steelhead trout and coho salmon, whose populations have been in decline, were noticeably absent from both watersheds. … The mystery prompted a near-decade-long study that was published last week in the journal Proceedings of the National Academy of Sciences, revealing the impact of one “severely dry” California winter that dramatically altered the ranges of three native species, and in some cases, caused them to completely vanish from the watersheds where they once thrived. But it also demonstrated the resilience of coho and chinook salmon and steelhead trout, paving the way for how the fish can be better protected in the years to come.

The $20B question hanging over America’s struggling farmers

As Earth heats up, the growing frequency and intensity of disasters like catastrophic storms and heat waves are becoming a mounting problem for the people who grow the planet’s food. Warming is no longer solely eroding agricultural productivity and food security in distant nations or arid climates. It’s throttling production in the United States. Farmers and ranchers across the country lost at least $20.3 billion in crops and rangeland to extreme weather last year, according to a new Farm Bureau report that crowned the 2024 hurricane season “one of the most destructive in U.S. history” and outlined a long list of other climate-fueled impacts. … California endured nearly all the same weather challenges as the south-central U.S. and the upper Midwest, costing its agricultural sector $1.4 billion.

On the heels of a dry winter, firefighters around the US brace for wildfire risks

From the southwestern U.S. to Minnesota, Iowa and even parts of New Jersey, it seemed that winter never materialized. Many communities marked their driest winters on record, snowpack was nearly nonexistent in some spots, and vegetation remains tinder dry — all ingredients for elevated wildfire risks. … A new wildfire outlook will be released Tuesday. While California isn’t among those areas facing significant potential for wildfires at the moment, deadly fires in January torched more urban area than any other fire in that state since at least the mid-1980s.

Months of short-term drought affect Arizona’s water levels. Here’s how

… Phoenix endured its second-longest dry spell on record, with 159 days without measurable rainfall from the end of a lackluster 2024 monsoon through January 2025. In Flagstaff, Arizona’s snowiest city, snow on the peaks during most of the season was created by Snowbowl snow machines. While a few early March storm systems brought snow and rain across much of the state, it won’t be enough to offset months of extreme drought. “It’s going to do very little to move the drought indices in both the short and long term,” said Michael Crimmins, a climatologist at the University of Arizona. “We have precipitation deficits that extend all the way back to the summer. It’s just too late in the season.”

Tuesday Top of the Scroll: Study says California’s 2023 snowy rescue from megadrought was a freak event. Don’t get used to it

Last year’s snow deluge in California, which quickly erased a two decade long megadrought, was essentially a once-in-a-lifetime rescue from above, a new study found. Don’t get used to it because with climate change the 2023 California snow bonanza —a record for snow on the ground on April 1 — will be less likely in the future, said the study in Monday’s journal Proceedings of the National Academy of Sciences. … UCLA climate scientist Daniel Swain, who wasn’t part of the study but specializes in weather in the U.S. West, said, “I would not be surprised if 2023 was the coldest, snowiest winter for the rest of my own lifetime in California.”

As climate hazards converge, health risks rise in California

State health officials know that extreme heat can cost lives and send people to the hospital, just like wildfire smoke. Now, new research finds that when people are exposed to both hazards simultaneously — as is increasingly the case in California — heart and respiratory crises outpace the expected sum of hospitalizations compared to when the conditions occur separately. … The study joins a growing body of research about the intersection of different climate risks. Last month, California-based think-tank the Pacific Institute published a report about how converging hazards — including wildfires, drought, flooding, sea level rise and intensifying storms — are harming access to drinking water and sanitation in California and other parts of the world. The deadly 2018 Camp fire in Butte County impacted an estimated 2,438 private wells, the report said.

Water conservation has become a way of life throughout the West with a growing recognition that water supply is not unlimited.

Drought is the most common motivator of increased water conservation. However, the gradual drying of the West due to climate change means the amount of fresh water available for drinking, irrigation, industry and other uses must be used as efficiently as possible.

High-Tech Mapping of Central Valley’s Underground Blazes Path to Drought Resilience
WESTERN WATER NOTEBOOK: Aerial Surveillance Reveals Best Spots to Store Floodwater for Dry Times but Delivering the Surplus Remains Thorny

Helicopter towing an AEM loopA new underground mapping technology that reveals the best spots for storing surplus water in California’s Central Valley is providing a big boost to the state’s most groundwater-dependent communities.

The maps provided by the California Department of Water Resources for the first time pinpoint paleo valleys and similar prime underground storage zones traditionally found with some guesswork by drilling exploratory wells and other more time-consuming manual methods. The new maps are drawn from data on the composition of underlying rock and soil gathered by low-flying helicopters towing giant magnets.

The unique peeks below ground are saving water agencies’ resources and allowing them to accurately devise ways to capture water from extreme storms and soak or inject the surplus underground for use during the next drought.

“Understanding where you’re putting and taking water from really helps, versus trying to make multimillion-dollar decisions based on a thumb and which way the wind is blowing,” said Aaron Fukuda, general manager of the Tulare Irrigation District, an early adopter of the airborne electromagnetic or AEM technology in California.

Upper Colorado River States Add Muscle as Decisions Loom on the Shrinking River’s Future
WESTERN WATER NOTEBOOK: Upper Basin States Seek Added Leverage to Protect Their River Shares Amid Difficult Talks with California and the Lower Basin

The White River winds and meanders through a valley.The states of the Lower Colorado River Basin have traditionally played an oversized role in tapping the lifeline that supplies 40 million people in the West. California, Nevada and Arizona were quicker to build major canals and dams and negotiated a landmark deal that requires the Upper Basin to send predictable flows through the Grand Canyon, even during dry years.

But with the federal government threatening unprecedented water cuts amid decades of drought and declining reservoirs, the Upper Basin states of Wyoming, Utah, Colorado and New Mexico are muscling up to protect their shares of an overallocated river whose average flows in the Upper Basin have already dropped 20 percent over the last century.

They have formed new agencies to better monitor their interests, moved influential Colorado River veterans into top negotiating posts and improved their relationships with Native American tribes that also hold substantial claims to the river.

WESTERN WATER IN-DEPTH: January storms jump-started recharge projects in badly overdrafted San Joaquin Valley, but hurdles with state permits and infrastructure hindered some efforts

An intentionally flooded almond orchard in Tulare CountyIt was exactly the sort of deluge California groundwater agencies have been counting on to replenish their overworked aquifers.

The start of 2023 brought a parade of torrential Pacific storms to bone dry California. Snow piled up across the Sierra Nevada at a near-record pace while runoff from the foothills gushed into the Central Valley, swelling rivers over their banks and filling seasonal creeks for the first time in half a decade.    

Suddenly, water managers and farmers toiling in one of the state’s most groundwater-depleted regions had an opportunity to capture stormwater and bank it underground. Enterprising agencies diverted water from rushing rivers and creeks into manmade recharge basins or intentionally flooded orchards and farmland. Others snagged temporary permits from the state to pull from streams they ordinarily couldn’t touch.

As Colorado River Flows Drop and Tensions Rise, Water Interests Struggle to Find Solutions That All Can Accept
WESTERN WATER IN-DEPTH: Chorus of experts warn climate change has rendered old assumptions outdated about what the Colorado River can provide, leaving painful water cuts as the only way forward

Photo shows Hoover Dam’s intake towers protruding from the surface of Lake Mead near Las Vegas, where water levels have dropped to record lows amid a 22-year drought. When the Colorado River Compact was signed 100 years ago, the negotiators for seven Western states bet that the river they were dividing would have ample water to meet everyone’s needs – even those not seated around the table.

A century later, it’s clear the water they bet on is not there. More than two decades of drought, lake evaporation and overuse of water have nearly drained the river’s two anchor reservoirs, Lake Powell on the Arizona-Utah border and Lake Mead near Las Vegas. Climate change is rendering the basin drier, shrinking spring runoff that’s vital for river flows, farms, tribes and cities across the basin – and essential for refilling reservoirs.

The states that endorsed the Colorado River Compact in 1922 – and the tribes and nation of Mexico that were excluded from the table – are now straining to find, and perhaps more importantly accept, solutions on a river that may offer just half of the water that the Compact assumed would be available. And not only are solutions not coming easily, the relationships essential for compromise are getting more frayed.

Winter Outlook Workshop
Dec. 8th Workshop in Irvine Focused on Ability to Predict Winter Precipitation

The three-year span, 2019 to 2022, was officially the driest ever statewide going back to 1895 when modern records began in California. But that most recent period of overall drought also saw big swings from very wet to very dry stretches such as the 2021-2022 water year that went from a relatively wet Oct.-Dec. beginning to the driest Jan.-March period in the state’s history.

With La Niña conditions predicted to persist into the winter, what can reliably be said about the prospects for Water Year 2023? Does La Niña really mean anything for California or is it all washed up as a predictor in this new reality of climate whiplash, and has any of this affected our reliance on historical patterns to forecast California’s water supply?

Participants found out what efforts are being made to improve sub-seasonal to seasonal (S2S) precipitation forecasting for California and the Colorado River Basin at our one-day Winter Outlook Workshop December 8 in Irvine, CA.

Amelia Flores, chairwoman of the Colorado River Indian Tribes.As water interests in the Colorado River Basin prepare to negotiate a new set of operating guidelines for the drought-stressed river, Amelia Flores wants her Colorado River Indian Tribes (CRIT) to be involved in the discussion. And she wants CRIT seated at the negotiating table with something invaluable to offer on a river facing steep cuts in use: its surplus water.

CRIT, whose reservation lands in California and Arizona are bisected by the Colorado River, has some of the most senior water rights on the river. But a federal law enacted in the late 1700s, decades before any southwestern state was established, prevents most tribes from sending any of its water off its reservation. The restrictions mean CRIT, which holds the rights to nearly a quarter of the entire state of Arizona’s yearly allotment of river water, is missing out on financial gain and the chance to help its river partners.

What is Drought?

Drought – an extended period of limited or no precipitation – is a fact of life in California and the West, with water resources following boom-and-bust patterns. During California’s 2012-2016 drought, much of the state experienced severe drought conditions: significantly less precipitation and snowpack, reduced streamflow and higher temperatures. Those same conditions began reappearing in late 2020, prompting Gov. Gavin Newsom in May of 2021 to declare drought emergencies in watersheds across 41 counties in California. Restrictions were later extended to all 58 counties. Gov. Newsom relaxed those restrictions finally in March 2023, after an exceptionally wet winter filled reservoirs and packed the Sierra Nevada with record snowfall.

California Weighs Changes for New Water Rights Permits in Response to a Warmer and Drier Climate
WESTERN WATER NOTEBOOK: State Water Board report recommends aligning new water rights to an upended hydrology

The American River in Sacramento in 2014 shows the effects of the 2012-2016 drought. Climate change is expected to result in more frequent and intense droughts and floods. As California’s seasons become warmer and drier, state officials are pondering whether the water rights permitting system needs revising to better reflect the reality of climate change’s effect on the timing and volume of the state’s water supply.

A report by the State Water Resources Control Board recommends that new water rights permits be tailored to California’s increasingly volatile hydrology and be adaptable enough to ensure water exists to meet an applicant’s demand. And it warns that the increasingly whiplash nature of California’s changing climate could require existing rights holders to curtail diversions more often and in more watersheds — or open opportunities to grab more water in climate-induced floods.

Wednesday Top of the Scroll: Red alert sounding on California drought, as farmers get less water

A government agency that controls much of California’s water supply released its initial allocation for 2021, and the numbers reinforced fears that the state is falling into another drought. The U.S. Bureau of Reclamation said Tuesday that most of the water agencies that rely on the Central Valley Project will get just 5% of their contract supply, a dismally low number. Although the figure could grow if California gets more rain and snow, the allocation comes amid fresh weather forecasts suggesting the dry winter is continuing. The National Weather Service says the Sacramento Valley will be warm and windy the next few days, with no rain in the forecast.

Drought in 2016 plunged its storage to about 8 percent of capacity.The southern part of California’s Central Coast from San Luis Obispo County to Ventura County, home to about 1.5 million people, is blessed with a pleasing Mediterranean climate and a picturesque terrain. Yet while its unique geography abounds in beauty, the area perpetually struggles with drought.

Indeed, while the rest of California breathed a sigh of relief with the return of wet weather after the severe drought of 2012–2016, places such as Santa Barbara still grappled with dry conditions.

Could “Black Swan” Events Spawned by Climate Change Wreak Havoc in the Colorado River Basin?
WESTERN WATER NOTEBOOK: Scientists say a warming planet increases odds of extreme drought and flood; officials say they’re trying to include those possibilities in their plans

Runoff from what some describe as an "epic flood" in 1983 strained the capacity of Glen Canyon Dam to convey water fast enough.  The Colorado River Basin’s 20 years of drought and the dramatic decline in water levels at the river’s key reservoirs have pressed water managers to adapt to challenging conditions. But even more extreme — albeit rare — droughts or floods that could overwhelm water managers may lie ahead in the Basin as the effects of climate change take hold, say a group of scientists. They argue that stakeholders who are preparing to rewrite the operating rules of the river should plan now for how to handle these so-called “black swan” events so they’re not blindsided.

With Drought Plan in Place, Colorado River Stakeholders Face Even Tougher Talks Ahead On The River’s Future
WESTERN WATER IN-DEPTH: Talks are about to begin on a potentially sweeping agreement that could reimagine how the Colorado River is managed

Lake Mead, behind Hoover Dam, shows the effects of nearly two decades of drought. Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.

Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.

As Deadline Looms for California’s Badly Overdrafted Groundwater Basins, Kern County Seeks a Balance to Keep Farms Thriving
WESTERN WATER SPOTLIGHT: Sustainability plans required by the state’s groundwater law could cap Kern County pumping, alter what's grown and how land is used

Water sprinklers irrigate a field in the southern region of the San Joaquin Valley in Kern County.Groundwater helped make Kern County the king of California agricultural production, with a $7 billion annual array of crops that help feed the nation. That success has come at a price, however. Decades of unchecked groundwater pumping in the county and elsewhere across the state have left some aquifers severely depleted. Now, the county’s water managers have less than a year left to devise a plan that manages and protects groundwater for the long term, yet ensures that Kern County’s economy can continue to thrive, even with less water.

Southern California Water Providers Think Local in Seeking to Expand Supplies
WESTERN WATER SIDEBAR: Los Angeles and San Diego among agencies pursuing more diverse water portfolio beyond imports

The Claude “Bud” Lewis Desalination Plant in Carlsbad last December marked 40 billion gallons of drinking water delivered to San Diego County during its first three years of operation. The desalination plant provides the county with more than 50 million gallons of water each day.Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.

In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)

Imported Water Built Southern California; Now Santa Monica Aims To Wean Itself Off That Supply
WESTERN WATER SPOTLIGHT: Santa Monica is tapping groundwater, rainwater and tighter consumption rules to bring local supply and demand into balance

The Santa Monica Urban Runoff Recycling Facility (SMURRF) treats dry weather urban runoff to remove pollutants such as sediment, oil, grease, and pathogens for nonpotable use.Imported water from the Sierra Nevada and the Colorado River built Southern California. Yet as drought, climate change and environmental concerns render those supplies increasingly at risk, the Southland’s cities have ramped up their efforts to rely more on local sources and less on imported water.

Far and away the most ambitious goal has been set by the city of Santa Monica, which in 2014 embarked on a course to be virtually water independent through local sources by 2023. In the 1990s, Santa Monica was completely dependent on imported water. Now, it derives more than 70 percent of its water locally.

It’s high-stakes time in Arizona. The state that depends on the Colorado River to help supply its cities and farms — and is first in line to absorb a shortage — is seeking a unified plan for water supply management to join its Lower Basin neighbors, California and Nevada, in a coordinated plan to preserve water levels in Lake Mead before they run too low.

If the lake’s elevation falls below 1,075 feet above sea level, the secretary of the Interior would declare a shortage and Arizona’s deliveries of Colorado River water would be reduced by 320,000 acre-feet. Arizona says that’s enough to serve about 1 million households in one year.

‘Ridiculously Resilient Ridge,’ Climate Change and the Future of California’s Water
WESTERN WATER Q&A: Climate scientist Daniel Swain

Daniel SwainEvery day, people flock to Daniel Swain’s social media platforms to find out the latest news and insight about California’s notoriously unpredictable weather. Swain, a climate scientist at the Institute of the Environment and Sustainability at UCLA, famously coined the term “Ridiculously Resilient Ridge” in December 2013 to describe the large, formidable high-pressure mass that was parked over the West Coast during winter and diverted storms away from California, intensifying the drought.

Swain’s research focuses on atmospheric processes that cause droughts and floods, along with the changing character of extreme weather events in a warming world. A lifelong Californian and alumnus of University of California, Davis, and Stanford University, Swain is best known for the widely read Weather West blog, which provides unique perspectives on weather and climate in California and the western United States. In a recent interview with Western Water, he talked about the Ridiculously Resilient Ridge, its potential long-term impact on California weather, and what may lie ahead for the state’s water supply.

Better Forecasting Is Key to Improved Drought and Flood Response

Marysville flooding

In a state with such topsy-turvy weather as California, the ability of forecasters to peer into the vast expanse of the Pacific Ocean and accurately predict the arrival of storms is a must to improve water supply reliability and flood management planning.

The problem, according to Jeanine Jones, interstate resources manager with the state Department of Water Resources, is that “we have been managing with 20th century technology with respect to our ability to do weather forecasting.”

Drought’s Impact on Fiscal Planning Highlights PPIC Report
Suppliers need “proactive” drought pricing to prevent cash crunch

During drought, people conserve water. That’s a good thing for public water agencies and the state as a whole but the reduction in use ultimately means less money flowing into the budgets of those very agencies that need funds to treat water to drinkable standards, maintain a distribution system, and build a more drought-proof supply.

“There are two things that can’t happen to a water utility – you can’t run out of money and you can’t run out of water,” said Tom Esqueda, public utilities director for the city of Fresno. He was a panelist at a June 16 discussion in Sacramento about drought resiliency sponsored by the Public Policy Institute of California (PPIC).

Punishing Drought Pushes California’s Water Supply Deeper in Arrears

Lake Oroville September 2015. Photo by DWR

Years of drought have sapped California’s water supply, creating an accumulated deficit exacerbated by increasingly warmer temperatures, a top researcher said at a recent briefing.

Michael Dettinger, research hydrologist with the U.S. Geological Survey, said parts of California have fallen more than two years behind where they should be in terms of receiving “normal” precipitation. The situation augurs what would be expected under projected climate change conditions as average annual temperatures warm and the snow level declines.

When conditions become dry, water storage declines and water conservation mandates make news headlines; questions from the public often surface about what appear to be easy solutions to augment the state’s water supply. But the answers can be complicated and, in the end, there is no silver bullet to ensure a resilient water supply, especially during drought.

We explore “frequently asked questions” often posed by the public and provide answers below. Simply click on the question for the answer to appear.

Historic Drought and the Colorado River: Today and Tomorrow
November/December 2015

The dramatic decline in water levels in Lake Mead and Lake Powell is perhaps the most visible sign of the historic drought that has gripped the Colorado River Basin for the past 16 years. In 2000, the reservoirs stood at nearly 100 percent capacity; today, Lake Powell is at 49 percent capacity while Lake Mead has dropped to 38 percent. Before the late season runoff of Miracle May, it looked as if Mead might drop low enough to trigger the first-ever Lower Basin shortage determination in 2016.

Finding the Right Balance: Managing Delta Salinity in Drought
September/October 2014

In wet years, dry years and every type of water year in between, the daily intrusion and retreat of salinity in the Sacramento-San Joaquin Delta is a constant pattern.

The cycle of ebb and flood is the defining nature of an estuary and prior to its transformation into an agricul­tural tract in the mid-19th century, the Delta was a freshwater marsh with plants, birds, fish and wildlife that thrived on the edge of the saltwater/freshwater interface.

Drought

Lake Oroville shows the effects of drought in 2014.

Drought—an extended period of limited or no precipitation—is a fact of life in California and the West, with water resources following boom-and-bust patterns. During California’s 2012–2016 drought, much of the state experienced severe drought conditions: significantly less precipitation and snowpack, reduced streamflow and higher temperatures. Those same conditions reappeared early in 2021 prompting Gov. Gavin Newsom in May to declare drought emergencies in watersheds across 41 counties in California.

El Niño/La Niña

California’s seasonal weather is influenced by El Niño and La Niña – temporary climatic conditions that, depending on their severity, make the weather wetter or drier than normal.

El Niño and La Niña episodes typically last 9 to 12 months, but some may last for years. While their frequency can be quite irregular, El Niño and La Niña events occur on average every two to seven years. Typically, El Niño occurs more frequently than La Niña, according to the National Oceanic and Atmospheric Administration (NOAA).

When a drought occurs as it has this year, the response is couched in the three Rs of the waste hierarchy: reduce, reuse and recycle.

The reduction part is well-known. State and local officials are urging people to use less water in everything they do, from landscape irrigation to shorter showers. Spurred by California’s difficulties, Gov. Arnold Schwarzenegger on June 4 declared a statewide drought. On July 10, the governor and Sen. Dianne Feinstein announced their support of the Safe, Clean, Reliable Drinking Water Supply Act of 2008 – a $9.3 billion bond proposal that would allocate $250 million for water recycling projects.
