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.
In a few months, scientists, farmers and water managers will get answers to such questions as: Will a drought occur and if so, where? Which plants die first? Which species are adept at absorbing carbon dioxide, a gas that is overheating our planet? Who will they ask? The space botanist.
A top official from the Southern Nevada Water Authority is calling on states that rely on the Colorado River to resolve their differences before a growing dispute derails decades of cooperation on the river. … The fight comes as Nevada, Arizona and California continue work on a drought contingency plan aimed at keeping Lake Mead out of shortage by voluntarily leaving more water in the reservoir.
The Pacific Fishery Management Council (PFMC) approved reduced recreational and commercial ocean salmon seasons for the West Coast on April 10. The reduction in fishing days this season amounts to cuts of about a third for the ocean sport fishery and over half of the commercial fishery, compared to a normal season.
We explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

This winter’s wild swings in weather – an early lack of rain, then late-season Sierra snowstorms, followed by a torrent of subtropical moisture – shows the need in California for long-range tools to better manage water supply.
At a Paleo Drought Workshop in San Pedro on April 19, six experts will discuss research on centuries-long precipitation and streamflow records, new forecasting tools and planning strategies to help reduce Southern California’s vulnerability to drought.
April is often a time of abundance in the mountains of the American West, when snowpack is at or near its peak, and forecasters work to determine how much runoff will course through our rivers and fill reservoirs later in the season. This year, across much of the West, particularly the Southwest, there’s little in the way of abundance. At Lake Powell, the second-largest reservoir in the West, runoff is predicted to be only 43 percent of average.
Learn what new tree-ring studies in Southern California watersheds reveal about drought, hear about efforts to improve subseasonal to seasonal weather forecasting and get the latest on climate change impacts that will alter drought vulnerability in the future.
At our Paleo Drought Workshop on April 19th in San Pedro, you will hear from experts at NASA Jet Propulsion Laboratory, University of Arizona and California Department of Water Resources.
Since Gov. Jerry Brown called off California’s drought emergency a year ago, we Californians seem to have gotten a little lazy when it comes to water conservation. We’ve started watering our lawns more often.
Dramatic swings in weather patterns over the past few years in California are stark reminders of climate variability and regional vulnerability. Alternating years of drought and intense rain events make long-term planning for storing and distributing water a challenging task.
Current weather forecasting capabilities provide details for short time horizons. Attend the Paleo Drought Workshop in San Pedro on April 19 to learn more about research efforts to improve sub-seasonal to seasonal precipitation forecasting, known as S2S, and how those models could provide more useful weather scenarios for resource managers.
California’s drought-to-deluge cycle can mask the dangers Mother Nature can have in store. During one of the driest March-through-February time periods ever recorded in Southern California, an intense storm dumped so much rain on Montecito in January that mudflows slammed into entire rows of homes.
[Idaho Rep. Mike] Simpson, who chairs an Appropriations subcommittee on energy and water development, called the wildfire fund one of the most significant pieces of legislation he has worked on in Congress. The concept is simple, he said: Treat catastrophic wildfires like other natural disasters.
We ventured through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
Arizona will be hardest hit if 17 years of drought keep drying up a reservoir serving much of the Southwest, but the state’s lawmakers and governor don’t agree on how to keep water in the lake or who should be in charge. Lake Mead, a man-made reservoir fed by the Colorado River, is an essential water supply for several western states that will take a hit if lake levels dip much lower.
A pair of storms moving across the Bay Area this week and into the Sierra Nevada could dump eight feet of snow at higher elevations, said Mike Kochasic, meteorologist at the National Weather Service in Sacramento. And although rain and snow are expected to remain far below average for the season after a bone-dry January and February, it’s still a relief to everyone from skiers to the state’s drought monitors.
Just how bad was California’s last drought? For most of Southern California, it was either the worst or second worst since the century Columbus landed in the New World, the Ottoman empire was started and Joan of Arc was burned at the stake.
Despite the recent storm that pummeled the Sierra with snow and scattered rain in the valleys and along the coast, California remains unseasonably dry with 47 percent of the state experiencing at least “moderate drought” conditions, according to the federal government’s Drought Monitor.
After a historically wet season last year, relatively little precipitation has fallen this year in California during two of the three historically wettest months. Officials are urging stricter water conservation and caution drier months ahead. After last week’s rains, the Sierra snowpack — a critical factor in water availability — climbed to just 39 percent of normal.
Anglers hoping to catch Chinook salmon this year along the San Francisco Bay and in the Central Valley’s rivers are likely to see curtailed fishing seasons, due to poor fish numbers linked to California’s historic five-year drought.
This April 19th workshop in San Pedro was focused on helping Southern California water agencies and others to gain information for improving drought preparedness and updating Urban Water Management Plans. The workshop was sponsored by the California Department of Water Resources (DWR) and the Water Education Foundation.

Machines that prod clouds to make snow may sound like something out of an old science fiction movie. But worsening water scarcity, combined with new evidence that “cloud seeding” can work, is spurring states, counties, water districts and power companies across the thirsty West to use the strategy.
After one year of torrential respite, drought may have returned to California, and with it, a renewal of the state’s perpetual conflict over water management. State and federal water systems have told farmers not to expect more than a fifth of their paper allocations, the state Water Resources Control Board is weighing a new regime of mandatory conservation, and supporters of more reservoirs are complaining about the glacial pace of spending $2.7 billion set aside in a water bond for more storage.
Irrigation season was delayed in 2017 as storm after storm kept farm and garden soil moist. Fast-forward to 2018, which has started out very dry and brought calls to fill the canals early. So are we back to serious drought in the Northern San Joaquin Valley, which endured one from 2012 to 2016?
Overall water use is climbing in Southern California as that part of the state plunges back into drought, driving state and regional water managers as they consider permanently reinstating some watering bans and conservation programs.
Government at all levels moves at a glacial pace, especially when it’s trying to deal with the complex and contentious issue of water. Four years ago in the midst of a scary, five-year drought — one of the state’s driest periods in recorded history — voters eagerly approved a $7.5-billion water bond proposal, Proposition 1. The vote was a lopsided 67% to 33%.
Every 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.
The lack of rain and snow in California has people wondering if we’re headed into another drought. … To find out what the lack of precipitation means for the state, we asked our social media audience for questions. And we reached out to experts across the state to answer them.
A bipartisan group of members of Congress from California and other Western states had been pushing a policy fix that would create a new funding stream to fight fires, leaving more money for the U.S. Park Service to manage forests and prevent fires. Under current law, firefighting is not funded out of the same natural disaster account used to respond to hurricanes or tornadoes.
A partnership of state and local agencies working to help homeowners affected by California’s multi-year drought finished connecting 755 homes to a safe, reliable, permanent water supply. All households participating in the East Porterville Water Supply Project have now been connected to the City of Porterville’s municipal water system.
Hoping for a March Miracle to bail out California’s dry winter? It’s not likely. A review of more than 100 years of rainfall records of major cities in California — including San Jose, Los Angeles, San Diego, Santa Rosa, Redding and Fresno — shows that none have ever finished the rainy season with normal rainfall totals after ending January with the amount of rain they’ve had so far this winter.
Many Western reservoirs are full, and downpours have triggered floods and deadly mudslides in parts of California. But all that water isn’t enough to save the West from another drought. Most of the region has slipped back into the drought conditions that have plagued it on and off for the past two decades—alarming water managers across several states.
California’s brief escape from severe drought ended Thursday after scientists declared more than 40 percent of the state in moderate drought and water officials confirmed lower-than-normal snowpack in the Sierra Nevada.
The T-shirt-wearing temperatures and lack of winter rain have combined to push nearly half of California into all-too-familiar territory: a state of drought. … At Phillips Station south of Lake Tahoe, where state water officials base their monthly snow surveys, hydrologists on Thursday found just 13 percent of average snowpack.
The drought could be crippling but the wine will be good. That is the happy conclusion of a study published today in the journal, Science. … That means farmers may not need to water their vineyards as much as previously thought during a dry spell.
Hampered by hot weather and a stubborn high-pressure ridge that has blocked winter storms, California’s Sierra Nevada snowpack — a key source of the state’s water supply — on Tuesday was a paltry 30 percent of normal. The last time there was so little Sierra snow at the end of January was in 2015, when it was 25 percent of its historic average.
A dystopian drama is unfolding in Cape Town, a popular tourist destination of nearly 4 million on the coast of South Africa that in April is expected to become the modern world’s first major city to run out of water after three years of drought. For Californians, who panted through five years of record drought before last winter and have seen a fairly dry winter so far this year, it raises the worrisome question: Could it happen here?
California’s recent wildfires have been nearly unprecedented in terms of their destructiveness and size and the season in which they burned. The Thomas Fire, for example, has grown into one of the largest wildfires in the state’s history, devouring thousands of acres daily as it moves from Ventura to Santa Barbara at a time of year more prone to gray skies and cold rain than burning forests.
Rising temperatures from climate change are having a noticeable effect on how much water is flowing down the Colorado River. Read the latest River Report to learn more about what’s happening, and how water managers are responding.
With the country and the world facing increasing strain on water resources, beer companies, including craft brewers, are learning how to do more with less water. … Craft brewers have recently struggled with water shortages in the American West. During the California drought, the city of Chico asked Sierra Nevada Brewing to reduce its water usage by more than 30 percent.
Californians are beginning to wonder: Is the state heading back into a drought? While experts say it’s still too early in the winter rainy season to say for sure, the evidence is accumulating, and the rain is definitely not.
California’s already towering Sierra Nevada summits rose to new heights during the drought, albeit by just a hair. A study by NASA scientists published Wednesday found that the granite peaks of the 400-mile range were pushed nearly an inch upward between 2011 and 2015, a phenomenon linked not only to known tectonic forces but the expansion of the land as it dried out and shed water weight.
The Sierra Nevada mountains grew nearly an inch taller during the recent drought and shrank by half an inch when water and snow returned to the area, according to new research from NASA’s Jet Propulsion Laboratory in La Cañada Flintridge. Researchers used 1,300 GPS stations throughout the mountain range to closely observe how its elevation changed during the drought.
States, federal and Mexican officials hailed a binational agreement this fall that they said could lead to a radical shift in how the region prepares for and responds to drought. But three months later, they appear no closer to a drought contingency plan, as negotiations have pitted states and water districts against one another, as the U.S. tries to hammer out details of the plan.
California’s forests are seeing a continued die-off of trees even a year after last year’s heavy rains ended the state’s crippling drought. The U.S. Forest Service announced Monday that 27 million trees died over the past 13 months after five dry years left them severely dehydrated and vulnerable to bark beetle attack.
This issue of Western Water discusses the challenges facing the Colorado River Basin resulting from persistent drought, climate change and an overallocated river, and how water managers and others are trying to face the future.
Winter is off to a dry start across the West, raising the specter of ongoing drought in many locations. The culprit could be La Niña – a periodic cooling of Pacific Ocean waters near the equator that often brings drought. And not just any La Niña, but a “double whammy” effect, which latest research concludes may cause even worse water shortages.
Severe wildfire seasons like the one that has devastated California this fall may occur more frequently because of climate change, scientists say. … The reason is an expected impact of climate change in California: increasing year-to-year variability in temperature and precipitation that will create greater contrast between drought years and wet years.
Hot, dry Santa Ana winds will likely whip up the unseasonably fierce wildfires ravaging Southern California on Thursday, forecasters said. The gales have come at the worst time, at the end of a long dry spell.
Even before the dramatic Southern California wildfires began their harrowing path this week, California was already experiencing its deadliest and most destructive fire season ever. And it’s only getting worse. … For Californians who welcomed one of the wettest, drought-busting winters early in 2017, the fury of the fires is startling.
California could be hit with significantly more dangerous and more frequent droughts in the near future as changes in weather patterns triggered by global warming block rainfall from reaching the state, according to new research led by scientists at Lawrence Livermore National Laboratory.
It could be a record year for salmon on the Mokelumne River, but not without some extraordinary human intervention. More than 15,200 adult salmon had returned to the fish hatchery below Camanche Dam as of last week. … This year’s strong return is good news in part because it shows how changes in hatchery operations can help fish survive the aftermath of a devastating drought.
It appears this is an average year for the number of fall-fun Chinook Salmon returning to spawn in the American River. The numbers were expected to be much lower because of high water temperatures and predators when the fish were juveniles heading to the ocean during the drought.
For decades, no matter the weather, the message has been preached to Californians: use water wisely, especially outdoors, which accounts for most urban water use. Enforcement of that message filters to the local level, where water agencies routinely target the notorious “gutter flooder” with gentle reminders and, if necessary, financial penalties. The situation turned critical during the 2012 to 2016 drought, when reservoirs sank to alarmingly low levels.

Last spring, the outlook for California’s 2017 Chinook salmon fishing season was dire. Years of drought had taken a toll on the rivers where salmon spawn, reducing them to lukewarm trickles. As a result, the number of adult fish was seriously depleted, reported scientists with the Pacific Fishery Management Council.
Droughts and floods are both a part of life in California as 2017 has so clearly demonstrated: It took one of the wettest winters on record to pull the state from the depths of a five-year drought. The state has invested funds in bulking up drought and flood protection in the past, but recent events highlighted the necessity of rejuvenating those efforts.
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.”
California Secretary for Natural Resources John Laird, who lives in Santa Cruz, said the state will be in trouble if another drought strikes as federal support remains uncertain. Key U.S. departmental vacancies could hamper negotiations for emergency relief, Laird said after the Democratic Women’s Club of Santa Cruz County meeting Saturday.
California could one day be uninhabitable. Fire. Heat. Floods. … Decamping for the 23rd session of the Conference of the Parties to the U.N. Convention on Climate Change, California academics and political leaders were mulling how to better deploy the distressing projections to give unwary citizens a better understanding of what’s at stake and compel them to see the wisdom of embracing sustainability.
Now, as a series of deadly fires rages in Wine Country, serious questions are once again being asked about the safety of overhead electrical wires in a state prone to drought and fierce winds. On Wednesday, Cal Fire said that investigators have started looking into whether toppled power wires and exploding transformers Sunday night may have ignited the simultaneous string of blazes.
A cascade of extreme weather events fed Northern California’s wildfires that exploded Sunday: Unusually high winds blew flames through unusually dense and dry vegetation, which sprung up following last winter’s heavy rains and then were toasted by months of record hot temperatures.
A lot of people and jobs in the Southwest rely on water from the Colorado River. According to a University of Arizona study, the river system contributes more than $840 billion to the Gross State Products of Arizona and California alone. But the region’s in a long-running drought.
The number of salmon returning to spawn at Coleman National Fish Hatchery in Anderson could reach historic lows this year — a legacy of the five-year drought that ended last year. At this time of year dozens of salmon would normally be teeming in the waters of Battle Creek near the hatchery.
Good habits die hard, it seems, after five years of epic drought – for most Californians, anyway. The historic dry spell from 2012 to 2016 prompted many state residents to reduce their water consumption, as did strict regulations imposed by state agencies and individual water districts.
SOUTHWEST (California, Nevada, Utah, Colorado, New Mexico and Arizona) -The average annual temperature has already gone up 1.56 degrees since 1901-1960 and is projected to rise another 4.8 degrees by mid-century and 8.65 degrees by the end of the century if carbon pollution continues unabated.
East Porterville took by far the hardest hit in the [San Joaquin] valley during the drought, state officials say. … The State Water Resources Control Board has responded with $35 million to connect East Porterville’s 300-plus dry homes to Porterville’s system. Another 400 homeowners who didn’t lose their wells have opted into the Porterville hookup to prevent future water problems.
Since the state’s drought officially ended earlier this year, there’s also been a precipitous drop in Californians worrying about having enough water. Last July, 62 percent said water supply was a big problem for the state.
Visitors to North Lake Tahoe this summer will notice the steady flow of the Truckee River, the high water level of Lake Tahoe, and dense green growth that has sprung up across the region thanks to record snow and rainfall this winter. But they’ll also see an increasing number of dead trees.
Several years of drought had severely depleted the Kern, a popular whitewater rafting destination known for its dramatic rapids. But this year’s wet winter created a record Sierra Nevada snowpack, and the melt has engorged the river with swift, frigid water.
As drought and water shortages become California’s new normal, more and more of the water that washes down drains and flushes down toilets is being cleaned and recycled for outdoor irrigation. But some public officials, taking cues from countries where water scarcity is a fact of life, want to take it further and make treated wastewater available for much more — even drinking.
The seemingly contradictory weather conditions — a heat wave and mountains still piled high with snow — are one final legacy of a historic winter that brought the most rain ever recorded in Northern California. Months of back-to-back storms finally pulled California out of its five-year drought. But they left behind up to 200 inches of snow.
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).
People came here for the forest, to live among 200-foot-tall pine trees that shaded their mountain cabins and scented the air. But in the span of two short years, tens of thousands of those trees are gone, ravaged by bark beetles until their green needles turned orange.
Republican Assemblyman Jim Patterson of Fresno recently claimed Gov. Jerry Brown has slashed nearly all the money in the state’s budget to help local governments remove dead and dying trees in California’s forests. More than 100 million trees have died in the forests due to drought and bark beetle infestations since 2010.
Already faced with unprecedented low numbers of returning salmon and drastically reduced fishing allowances, California’s fishing fleets and communities are not expected to find any relief in the next few years, according to testimony by a host of experts and regulators at the State Capitol on Wednesday.
The massive scale of California’s groundwater pumping is outlined in a study released Wednesday by researchers at UCLA and the University of Houston. The researchers conclude that California’s pending groundwater regulations remain woefully behind what is necessary to bring the state’s groundwater levels back into balance.
Researchers have issued a dire warning for California’s native trout and salmon: Three-quarters of them will be extinct in the next 100 years unless urgent action is taken. This bleak assessment came Tuesday from biologists at the UC Davis Center for Watershed Sciences and from California Trout, a nonprofit advocacy group.
From the Central Coast to the Sierra Nevada foothills, spring winds have dried timber and brush after a historically wet winter that isn’t expected to relieve the 2017 wildfire threat, a Cal Fire San Mateo-Santa Cruz Unit official said. Gov. Jerry Brown on Monday proclaimed Wildfire Awareness Week, citing a rise in dangerous wildfires in recent years.
A bill intended to prevent dying trees damaged by drought from falling onto utility lines on publicly owned federal land, sparking wildfires and electricity blackouts, passed out of the House Natural Resources Committee on Thursday.
First the drought ended. Now the last vestiges of mandatory conservation rules are over, too. California’s main water regulatory agency ended mandatory conservation regulations for urban residents Wednesday, following Gov. Jerry Brown’s official declaration that the drought ended April 7.
California’s brutal five-year drought did more than lead to water shortages and dead lawns. It increased electricity bills statewide by $2.45 billion and boosted levels of smog and greenhouse gases, according to a new study released Wednesday.
Californians’ electricity costs jumped by a combined $2.45 billion from 2012 to 2016 because of severe shortages of cheap hydroelectricity, according to an estimate released Wednesday by the Pacific Institute, an Oakland water policy think tank.
California’s historic five-year drought is officially over, washed away with the relentlessly drenching rains, floods and snowstorms of this winter. But just as tougher building codes and better emergency planning follow major earthquakes, the brutally dry years from 2012 to 2016 are already leaving a legacy, experts say, changing the way Californians use water for generations to come.
Knee-high tufts of grass dot the streets of Hardwick, a rural neighborhood with a few dozen homes hemmed in by vineyards and walnut and almond orchards in California’s agriculture-rich San Joaquin Valley.
California’s climate has long been dominated by cycles of intense dry conditions followed by heavy rain and snow. But never before in recorded history has the state seen such an extreme drought-to-deluge swing.
For the second year in a row, California officials are likely to shorten the chinook salmon season, making the local specialty costly and hard to find throughout the summer and possibly beyond. … The low numbers are due to lingering effects of the drought, because impacts on the population are felt about three or four years behind years with little rain.
After one of the wettest winters on record, Gov. Jerry Brown declared Friday that California’s historic drought is officially over for all but a handful of areas in the Central Valley. But after five years of severely dry conditions, California also is pressing forward with a dramatic overhaul of its conservation ethic for farms to cityscapes.
Gov. Jerry Brown declared the end of California’s drought emergency on Friday, stressing that water conservation must be a permanent part of life as the state adapts to climate change and prepares for the next drought.
tartlingly green hills, surging rivers and the snow-wrapped Sierra Nevada had already signaled what Gov. Jerry Brown made official Friday: The long California drought is over. Brown issued an executive order that lifts the drought emergency in all but a handful of San Joaquin Valley counties where some communities are still coping with dried-up wells.
California looks to be resuscitated this spring, with green stretching the length of the state and the desert erupting in a colorful mosaic fueled by a super bloom of flowers. The state’s wet winter has erased a surface drought more than five years in the making. Now, many reservoirs have been topped off, rivers are running and the snowpack – so meager just two years ago as to be almost unmeasurable – is piled 50ft (15m) high in some places.
Farmers employ tens of thousands of people in the San Joaquin Valley and run a $35 billion industry producing grapes, milk, oranges, almonds and dozens of other commodities sold in stores around the globe. Many of them supported Donald Trump for president, calculating that his promise to deliver more water to drought-starved valley farms would help them despite his hard-line stance on immigration.
Last summer it was a jarring symbol of California’s historic five-year drought. San Luis Reservoir — the vast lake along Highway 152 between Gilroy and Los Banos, the state’s fifth-largest reservoir and a key link in the water supply for millions of people and thousands of acres of Central Valley farmland — was just 10 percent full.
California’s water regulators are looking to strengthen their focus on climate change, adopting policies aimed at helping the state prepare for more severe floods, more extreme droughts and shrinking snowpack.
One year ago, just 5 percent of California was classified as free from drought. That number has been turned nearly upside down, and as of Thursday, 91 percent of the state is no longer in drought condition, according to federal scientists.
Going, going, but not gone yet. About 47 percent of California still faces a drought, and the conditions are severe in 11 percent of the state, according to the most recent weekly report from the U.S. Drought Monitor.
Both drought and floodwaters are testing California’s aging water infrastructure. A new NASA analysis shows too much groundwater pumping during the drought has caused the California Aqueduct to sink more than two feet near Avenal in Kings County.
The U.S. Drought Monitor shows that less than 2 percent of California is still experiencing severe drought impacts, but that small area is concentrated in southern Santa Barbara County and parts of neighboring Ventura and Los Angeles counties.
A healthy snow pack and steady rain have offered a fresh outlook to over five years of drought in California but the State Water Resources Control Board is expected to extend emergency regulations due to water supply problems in areas such as the Central Coast.
California’s historic drought may be winding down. But water officials across the Golden State are increasingly exploring a hidden but promising way to add to the state’s water supply: removing salt from the billions of gallons of brackish — or distastefully salty — water that lies deep below the Earth’s surface.
Roaring storms that brought California almost a year’s worth of snow and rain in a single month should make state water managers’ Sierra snowpack survey Thursday a celebration, marking this winter’s dramatic retreat of the state’s more than 5-year-drought, water experts say.
The ponderosa pine had taken root decades before the Revolutionary War, making a stately stand on this western Sierra Nevada slope for some 300 years, Nate Stephenson figures. Then came the beetle blitzkrieg.
Governor Brown has released a proposed budget that reaffirms the state’s commitment to boosting drought resiliency and battling climate change. … Although state money represent only a fraction of California’s total water sector spending (13%—the rest is mostly locally funded), it is an important piece of the funding pie.
San Luis Reservoir west of Los Banos is on its way to filling for the first time since 2011 as rain and snow bring the state additional relief from a punishing drought. Statewide, a series of storms over the past two weeks have allowed water managers to fill major reservoirs to above-normal levels for this time of year.
Much of California has gone from withered to water-logged this winter, but the state’s top water regulator is not ready to lift emergency conservation measures enacted during the height of the drought. … Water districts have been lobbying the board to back down.
With storms drenching much of California and snow blanketing the Sierra Nevada, the state’s top water regulators are grappling with how to shift from conservation rules devised during more than five years of drought to a long-term strategy for using water more sustainably.
With major reservoirs nearly full, the Sierra Nevada snowpack well above average and flood warnings in place for some rivers, federal scientists reported Thursday a continued weakening of California’s drought. … Even as state officials urged caution, they announced Wednesday that cites [sic] and farms will receive at least 60 percent of the maximum amount of water they are contracted to buy in the coming year from the State Water Project, up from just 20 percent two months ago.
The worst area of drought in California has significantly narrowed to a small region northwest of Los Angeles that has stubbornly failed to benefit from Pacific storms that have drenched much of the state since the fall and were lining up again Wednesday.
Deluged with a series of relentless storms this winter, more than 40 percent of California — including the Bay Area — is no longer in a drought for the first time in four years, a stark turnaround after one of the worst natural disasters in state history, a new federal report said Thursday morning.
Rescue workers used boats and firetrucks to evacuate dozens of Northern California residents from their flooded homes Wednesday as a drought-busting series of storms began to move out of the region after days of heavy rain and snow that toppled trees and created havoc as far north as Portland, Oregon.
Gov. Jerry Brown on Tuesday released a $177.1 billion spending plan that contains funds for drought, water rights management, continuation of the statewide conservation program Save Our Water and other key water programs.
As a result of the nearly weeklong deluge, water is flowing into California lakes and reservoirs, prompting dam operators to release supplies in advance of a storm expected next week. But it’s too early to say if the series of storms is a drought-buster.
If the storm systems keep coming, state and regional water managers say, 2017 could be the end of a dry spell that has, for more than five years, caused crops to wither, reservoirs to run dry and homeowners to rip out their lawns and plant cactus.
The powerful storms that soaked Northern California over the past week did more than trigger power outages, mudslides and flash floods. … Officially, California’s drought won’t end until Gov. Jerry Brown rescinds or revises the emergency drought declaration he signed in January 2014.
A lull in a series of powerful winter storms gave Northern California a chance Monday to clean up from widespread flooding while also assessing how all that moisture is altering the state’s once-grim drought picture.
After many long years of waiting, California’s drought relief may finally be here. … Central California is on track to be the second wettest water year on record, and Southern California is expected to tie the wettest year, which was the year of ‘68-’69.
As much of the state heads into a sixth year of drought, water officials on Wednesday, Jan. 4, cheered Californians’ continued conservation while urging them to stay stingy with water after residential savings slipped below 19 percent in November.
The first manual survey this year of California’s snowpack revealed Tuesday that it holds about half as much water as normal, casting a shadow on the state that’s hoping to dodge a sixth straight year of drought, officials said.
Around the start of each year, California water officials make a big show out of measuring the Sierra Nevada snowpack for reporters. Tuesday’s measurement before a throng of cameras was fairly bleak: Water content in the snowpack stood at just 53 percent of average, about a third as much water as the same time last year at that site.
Surveyors will plunge poles into the Sierra Nevada snowpack near Lake Tahoe on Tuesday, taking the season’s first measurement by hand of the snow’s water content as California flirts with a sixth year of drought.
The federal government will be pouring nearly a quarter-billion dollars into several dozen projects aimed at tackling the effects of drought in the West and restoring watersheds that provide drinking water to communities around the nation.
[Arizona] Department of Water Resources Director Tom Buschatzke is meeting with other Colorado River system users in Las Vegas at the annual Colorado River Water User Association Conference running through Dec. 16. … On Dec. 15, Secretary of the Interior Sally Jewell will unveil the program for management of the Colorado River between Lakes Powell and Mead.
When California water officials assess the drought, the first place they look is the northern Sierra Nevada mountains. Rain and snowmelt from the area feed into a complex system of rivers, canals and reservoirs that send water across the state.
California is working to put into place a framework that will help the state deal with its current water shortage, as well as future droughts that are likely to be more severe with a changing climate. “Making Water Conservation a Way of Life,” a draft report released last week, is the collective effort of five state agencies to fulfill Gov. Jerry Brown’s Executive Order B-37-16, signed in May 2016.
The water policy measure overwhelmingly passed by the House of Representatives on Thursday to build long-term water infrastructure across the Golden State is headed for a showdown with outgoing Sen. Barbara Boxer, who plans to mount a filibuster in the Senate on Friday as one of her final acts in Congress.
Despite a wet start to the fall in Northern California, nearly two-thirds of the state remains wracked by extreme drought. In the future, climate change is likely to make dry periods more frequent, more intense and longer.
Urban Californians used about 1.8 percent more water in October compared with a year earlier, state officials said Tuesday. It marked the fourth straight month in which conservation has slipped following the state’s decision to relax drought mandates.
Now, if past weather patterns are fulfilled this year, experts say, Northern California’s winter — and long-term relief from years of drought — could be just around the corner for the state’s most important watershed.
California’s water regulators will start using aerial images to measure the green grass and irrigated landscapes of hundreds of communities across the state as part of a new long-term strategy to boost conservation.
California officials crafting a new conservation plan for the state’s dry future drew criticism from environmentalists on Thursday for failing to require more cutbacks of farmers, who use 80 percent of the water consumed by people.
In a series of proposals released Wednesday, state officials said they might require urban water districts seeking to avoid state conservation mandates to prove they have a five-year water supply on hand.
In a case that could have statewide ramifications, a group of multimillionaire Hillsborough residents, including an early funder of Microsoft, has sued the town claiming that its drought rules and penalties intended to keep people from over-watering big lawns are illegal.
In a preliminary outlook, the state Department of Water Resources said it can count on allocating as little as 20 percent of requested water supplies to start, hinting drought fears are far from over in California.
California’s Department of Water Resources has made its initial projection of how much water public agencies can count on receiving from the canals and pipelines of the State Water Project next year: 20 percent of their full allotments.
More than 102 million dead trees now litter California’s drought-flayed forests, according to the latest aerial survey, a finding likely to fuel a heated public-lands debate during the incoming Trump administration.
President-elect Donald Trump might have trouble living up to one of his more sweeping campaign promises in California. On the stump in Fresno last May, he made headlines for declaring, “There is no drought” here.
Wastewater recycling is being hailed in many communities as the answer to ongoing drought problems. By cleaning sewage effluent to extract pure water, it’s possible to create a sustainable water supply that is cheaper than seawater desalination or buying a new water supply. But there’s a little-recognized downside to water recycling: It may damage wildlife habitats already imperiled by water scarcity.
The number of dead trees in California’s drought-stricken forests has risen dramatically to more than 102 million in what officials described as an unparalleled ecological disaster that heightens the danger of massive wildfires and damaging erosion. … Scientists say five years of drought are to blame for much of the destruction.
Lake Cachuma, a giant reservoir built to hold Santa Barbara County’s drinking water, has all but vanished in California’s historic drought. It reached an all-time low this summer — 7 percent capacity, which left a thick beige watermark that circles the hills framing the lake like an enormous bathtub ring.
How low can the Colorado go? When will we get back to “normal” winters? Can we blame it all on climate change? To address some of these questions, the Colorado River Research Group recently released a concise four-page paper explaining how climate change is affecting the river.
