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.
A new study by scientists at Utah State University shows that a
shrinking Great Salt Lake may exacerbate drought conditions
along the entire Wasatch Front. “As the Great Salt Lake
water body is shrinking, that local precipitation caused by a
storm event is going to decrease,” Dr. Wei Zhang, an associate
professor of climate science at USU and one of the study’s
authors, told FOX 13 News on Monday. Using a series of
meteorological models as a case study, USU researchers found
that, in essence, the shrinking Great Salt Lake can create its
own vicious cycle of drought. … The Great Salt Lake is
famous for its ability to amplify storms. “Lake-effect snow”
can pump out more snow in the mountains and boost Utah’s
lucrative ski industry.
Over the July 4 weekend, hundreds of fires sparked across
California, feeding on the hot, dry conditions of an ongoing
heat wave. But some of these fires were strange. They grew
rapidly and expanded their territory at a time when fires, like
people, traditionally rest: at night. … “Night won’t save
us,” said Kaiwei Luo, a doctoral student in environmental
sciences at the University of Alberta and the lead author of a
recent study in the journal Nature that found overnight burning
can cause fires to burn larger and longer. “With climate
change, we will see more and more overnight burning,” he said.
… Mr. Luo’s study found that while heat waves are a
big contributor to extreme fire behavior, drought conditions
could be the main driver. Understanding these factors
could help emergency managers and communities better prepare.
… If a fire starts in an area of drought, for example,
firefighters could anticipate that overnight burning is likely
to increase the fire’s range and severity.
Scientists at the United States Department of Agriculture
(USDA) Southwest Climate Hub and California Climate Hub have
developed a browsable map-based tool that addresses water
scarcity in the U.S. Southwest. The Water Adaptation Techniques
Atlas (WATA) consolidates over 200 case studies on research and
practices that water managers and producers can use to find
location-specific and topical information to make informed
decisions regarding water management. … water scarcity has
become a pressing issue with extremely hot temperatures and
severe prolonged droughts in a region already challenged by its
arid and semi-arid conditions. As reservoir and aquifer levels
drop, information about strategies to adapt to this new reality
is urgently needed. WATA provides information based on research
from USDA’s Agricultural Research Service and other sources
about practices for lessening the gap between water demand and
available supply, with an emphasis on cropping and irrigation
practices across the Southwest, including Arizona, California,
Nevada, New Mexico, and Utah.
With California experiencing extreme swings between severe
drought to torrential rain, the Department of Water Resources
(DWR) wanted to see if the State Water Project’s largest
reservoir, Lake Oroville, had shrunk (or lost storage capacity)
due to weather swings and almost six decades of service. DWR
utilized the latest terrain-mapping technology to determine if
there have been any changes in the lake’s volume to optimize
how the reservoir is operated and ensure accuracy in estimating
California’s water supply availability. … Starting with
an airplane-mounted LiDAR (Light Detection and Ranging) laser
system, DWR took advantage of the lake’s historically low water
levels in 2021 to first map portions of the basin that would
typically be under water during normal years. Then a boat
outfitted with multibeam-sonar bathymetry instruments spent
weeks in 2022 sending sonar pulses into the depths of Lake
Oroville to map its underwater surface terrain. What resulted
were highly detailed 3D topographic terrain models of the
bottom of the lake, which DWR engineers used to calculate a new
storage capacity of 3,424,753 acre-feet, approximately 3
percent less than previously estimated.
… Perhaps it would be better to develop less water-intensive
developments. Recreation is certainly what were known for, but
at what cost? Each golf course uses approximately 1,000-acre
feet of water yearly (326,000,000 gallons of water).
Before the existence of the Salton Sea, the Colorado River
created ancient Lake Cahuilla many times over thousands of
years, making it the largest fresh water inland lake in
California. Now the Salton Sea is on the brink of a health and
environmental disaster that will impact all of Southern
California. We are currently all affected by the some of the
worst air quality in the nation. —Written by Kerry Berman, interpretive guide, I-naturalist,
author of “Enchanted Valley Palm Springs and Beyond”
Record snowfall in recent years has not been enough to offset
long-term drying conditions and increasing groundwater demands
in the U.S. Southwest, according to a new analysis of NASA
satellite data. Declining water levels in the Great Salt Lake
and Lake Mead have been testaments to a megadrought afflicting
western North America since 2000. But surface water only
accounts for a fraction of the Great Basin watershed that
covers most of Nevada and large portions of California, Utah,
and Oregon. Far more of the region’s water is
underground. … A new look at 20 years of data …
shows that the decline in groundwater in the Great Basin far
exceeds stark surface water losses. … While new maps
show a seasonal rise in water each spring due to melting snow
from higher elevations, University of Maryland earth scientist
Dorothy Hall said occasional snowy winters are unlikely to stop
the dramatic water level decline that’s been underway in the
U.S. Southwest.
Water experts say that officials must work closely with
communities to efficiently manage groundwater systems amid
climate change — despite growing animosity among landowners.
Scientists and experts at the nonpartisan Water Education
Foundation’s third international groundwater conference Tuesday
said that, with so many styles of groundwater management,
strong partnerships are the only way to sustainably handle
water supplies within and beyond California.
How much money will it take to save the Colorado River? And is
money the answer?It turns out with money, as is with water,
every drop in the bucket helps and can work to achieve water
savings, restore ecosystems, provide additional recreational
opportunities and prevent flooding. … A Monday webinar hosted
by the Water Hub featuring local elected officials, nonprofit
organizations and others detailed some of the progress made so
far with on-the-ground projects, particularly in the Upper
Colorado River Basin and the look ahead. The projects targeted
water savings, agricultural efficiency, habitat restoration,
and flood and drought mitigation in a basin increasingly
challenged by drought that has scorched the West, sapped river
flows, increased sediment, and put in jeopardy wildlife and
vital aquatic ecosystems.
In a move to combat the drought crisis affecting the Colorado
River Basin, the Bureau of Land Management (BLM) announced on
Thursday an $11.1 million cooperative agreement with the
Foundation for America’s Public Lands. The partnership aims to
enhance drought resilience in the region, which is vital for
the millions of Americans who depend on the river for their
livelihoods. The funding, made available through the Inflation
Reduction Act under the Biden Administration, is set to bolster
efforts to ensure the sustainability of the Colorado River
Basin.
Tensions are rising in a border dispute between the United
States and Mexico. But this conflict is not about migration;
it’s about water. Under an 80-year-old treaty, the United
States and Mexico share waters from the Colorado River and the
Rio Grande, respectively. But in the grip of severe drought and
searing temperatures, Mexico has fallen far behind in
deliveries, putting the country’s ability to meet its
obligations in serious doubt. Some politicians say they cannot
give what they do not have. It’s a tough argument to
swallow for farmers in South Texas, also struggling with
a dearth of rain. They say the lack of water from Mexico
is propelling them into crisis, leaving the future of farming
in the balance. Some Texas leaders have called on the Biden
administration to withhold aid from Mexico until it makes good
on the shortfall.
… In the past 12 years, California has endured two multi-year
droughts, including a stretch from 2020 to 2022 that was the
state’s driest three-year period on record. California also
experienced two of the wettest winters on record, fueled by a
parade of atmospheric rivers that caused flooding in Santa
Clara County and across the state. If we fail to invest in
infrastructure now, we all will face serious challenges with
disadvantaged communities bearing the worst through
unaffordable water and increased flooding. That’s why Valley
Water and the Association of California Water Agencies are
advocating for a Climate Resilience Bond to be placed on the
November ballot with two-thirds of the funding going to water
infrastructure. -Written by Rick Callender, Chief Executive
Officer of Valley Water, and Dave Eggerton, Executive

After a year of dominance, El Niño’s wrath has come to end —
but it’s climate-churning counterpart, La Niña, is hot on its
heels and could signal a return to dryness for California. El
Niño is the warm phase of the El Niño Southern Oscillation,
sometimes referred to as ENSO. The climate pattern in the
tropical Pacific is the single largest driver of weather
conditions worldwide, and has been actively disrupting global
temperatures and precipitation patterns since its arrival last
summer. Among other effects, the El Niño event contributed to
months of record-high global ocean temperatures, extreme heat
stress to coral reefs, drought in the Amazon and Central
America, and record-setting atmospheric rivers on the U.S. West
Coast, the National Oceanic and Atmospheric Administration said
in its latest ENSO update.
Millions of people dependent on Himalayan snowmelt for water
face a “very serious” risk of shortages this year after one of
the lowest rates of snowfall, scientists warned
Monday. Snowmelt is the source of about a quarter of the
total water flow of 12 major river basins that originate high
in the region, the report said. ”This is a wake-up call
for researchers, policymakers, and downstream communities,”
said report author Sher Muhammad, from the Nepal-based
International Centre for Integrated Mountain Development
(ICIMOD). ”Lower accumulation of snow and
fluctuating levels of snow pose a very serious increased risk
of water shortages, particularly this year.” Snow and ice
on the Himalayas are a crucial water source for around 240
million people in the mountainous regions, as well as for
another 1.65 billion people in the river
valleys below, according to ICIMOD.
… Last year, Assemblymember Jim Wood (D-Healdsburg)
introduced a pivotal piece of legislation to enhance drought
preparedness and climate resiliency for North Coast watersheds.
Supported by a coalition of organizations and Tribal Nations,
and co-sponsored by CalTrout, AB 1272 promises a better future
for North Coast communities and the iconic species that live
there. North Coast communities are deeply connected to
salmon populations and rivers. Declining salmon numbers due to
severe droughts and water management challenges have led to the
closure of salmon fishing in 2023 and again this year.
Another winter without enough snow and rain has left much of
the western United States parched for water, according to
scientists monitoring a snow drought. Thanks to
below-normal precipitation during the water season, snow
drought conditions persist across most of the West, according
to a June 12 report from scientists at the National Oceanic and
Atmospheric Administration. While some regions such as the
Sierra Nevada range, improved over the winter, scientists say
many places will see further drought development or
intensification this summer. Many locations in Washington
and the northern Rocky Mountains received less than 15% of the
average rainfall, with eight weather stations in Montana and
two in Washington reporting record low rainfall values. In
Idaho, Montana and Washington, snow drought developed early in
the season and persisted, bringing snow water equivalent — the
water contained in a mountain’s snowpack — to 55 to 75% of the
normal amount.
The end of a two-year legal fight over who should pay, and how
much, to replenish the groundwater beneath Madera County could
be in sight. A motion to dismiss the lawsuit by a group of
farmers against the county is set to be heard June 18.
The outcome could determine whether Madera County, which acts
as the groundwater sustainability agency (GSA) for hundreds of
thousands of acres across three water subbasins, can finally
move forward on a host of projects to improve the water table
per the Sustainable Groundwater Management Act (SGMA). From the
farmers’ point of view, the outcome of this case could make or
break their farms, some that have been in their families for
generations.
Firefighters are battling wildfires in Brazil’s Pantanal, the
world’s largest tropical wetland. The Pantanal is home to
jaguars, giant anteaters and giant river otters. Close to
32,000 hectares have already been destroyed by the fires in the
state of Mato Grosso do Sul, local media report. Climate
experts say this year’s wildfire season has started earlier and
is more intense than in previous years. Firefighters said their
efforts to extinguish the flames were being hampered by high
winds over the weekend. The region has also seen less rain than
in other years, which has made it easier for the fires to
spread.
Dozens of environmental groups, renewable energy companies,
labor unions, water agencies and social justice advocates are
lobbying state lawmakers to place a multibillion dollar climate
bond on the November ballot. Sacramento lawmakers have been
bombarded with ads and pitches in support of a ballot proposal
that would have the state borrow as much as $10 billion to fund
projects related to the environment and climate change. “Time
to GO ALL IN on a Climate Bond,” says the ad from WateReuse
California, a trade association advocating for projects that
would recycle treated sewage and storm runoff into drinking
water. … Negotiations are ongoing in closed-door
meetings, but details emerged recently when two
spreadsheets of the proposed spending, one for an Assembly
bill known as AB 1567 and the other for the Senate’s SB 867,
were obtained by the news organization Politico. The two
plans, which would be combined into a single ballot measure,
include money for wildlife and land protection, safe drinking
water, shoring up the coast from erosion and wildfire
prevention.
The City of Corning will now be represented by Martin Spannaus
on the Tehama County Flood Control and Water Conservation
District Groundwater Commission upon the resignation of Cody
Lamb, who had served on the commission since June 2023.
Spannaus’s appointment received unanimous approval from the
City Council during its May 28 meeting. Spannaus is the city’s
former fire chief. … Spannaus and his wife, Joann, live on a
cattle and hay ranch west of Corning in the Corning Groundwater
Subbasin, which currently sits at a “high” priority rating.
For California’s Sierra Nevada, the winter of 2022-2023
delivered an epic snowpack that broke many records and busted a
severe drought. … Both hazardous and helpful, the banner year
was also of interest to snow scientists, such as Adrienne
Marshall, an assistant professor of geology and geological
engineering at the Colorado School of Mines in
Golden. Marshall was lead author of a paper published in
April in the Proceedings of the National Academy of Sciences
that introduces the term “snow deluge” to describe extreme snow
years like the one California weathered.
With temperatures spiking across California this week, now
is a great time to reserve your spot on our Headwaters Tour July
24-25 when we’ll explore the role of the Sierra
Nevada snowpack in the state’s water supply and how heatwaves
can accelerate snowmelt. The state’s critical ‘frozen
reservoir’ was slightly above average at the end of
the 2024 snow survey season, following an epic snowpack in 2023
that prompted widespread flooding and the resurrection of
Tulare Lake. During the July tour, we’ll also learn how
snowpack is measured and translated into forecasts of
California’s water supply for the year.
… The 2-day, 1-night
tour with an overnight in Lake
Tahoe travels up the Sierra foothills and into
the mountains within the American River and Yuba River
watersheds. Meadow restoration, climate change, wildfire
impact and more will be discussed as we pass through
Eldorado and Tahoe national forests.
The giant sequoia is so enormous that it was once believed to
be indestructible. High in California’s southern Sierra Nevada
mountains, the oldest trees – known as monarchs – have stood
for more than 2,000 years. Today, however, in Sequoia national
park, huge trunks lie sprawled on the forest floor, like blue
whale carcasses stranded on a beach. Many of these trees were
felled by a combination of drought and fire. But among the
factors responsible for the rising toll is a tiny new suspect:
the bark beetle. Along with wildfires and rising
temperatures, scientists fear that the insects could contribute
to the breakdown of Earth’s northern conifer forests, including
the potential dieback of the taiga, the vast ecosystem that
stretches across Canada, Scandinavia, Siberia and Alaska.
Cover crops are planted to protect and improve the soil between
annual crops such as tomatoes or between rows of tree and vine
crops, but growers may be concerned about the water use of
these plants that don’t generate income. “Cover crops are one
of the most popular practices we see farmers employ through
our Healthy Soils Program,” said Karen Ross, secretary of
the California Department of Food and Agriculture.
… These potential benefits are especially salient in the
San Joaquin Valley, where groundwater challenges are more
acute. A new report evaluates the water implications of cover
cropping practices to lay the groundwork for their adoption in
the context of the Sustainable Groundwater Management Act,
or SGMA, which is intended to protect groundwater resources
over the long-term. “Yes, cover crops require a nominal
amount of water to establish – and sometimes rainwater is
sufficient – but the myriad co-benefits are worth it,” Ross
said.
On a recent morning, visitors wandered around Mexico City’s
Metropolitan Cathedral, Latin America’s oldest — and one of its
largest. Walking from chamber to chamber, tourists snapped
images of dramatic ceiling-high altars, soaring columns and
sculptures. But there’s another unintended detail that stands
out: the cathedral is leaning. … This sinking, which is known
as land subsidence, crops up across the world. While it can be
subtle in many places — it pushes land down around an inch
or two a year in much of the U.S. — the rates in
Mexico City are some of the highest in the world. Some
areas in Mexico City are slipping as fast as 20 inches a year
in recent decades, according to researchers. Overall, the
clay layers under the soil have compressed by 17 percent in the
last century.
Drought is a hazard, but it needn’t be a disaster. That is,
provided all communities are adequately equipped before it
strikes. At the 10th World Water Forum, held in Bali from 18 to
25 May, experts urged decision-makers to prioritize drought
resilience in the face of climate change, drawing inspiration
from success cases around the globe. Representatives from the
scientific, non-profit, and technical sectors made the case for
building resilience to the world’s costliest and deadliest
hazard at an event featuring partners of the International
Drought Resilience Alliance (IDRA.) … “Drought and
desertification are not just problems for the Sahel region of
Africa and for developing countries,” said UNCCD policy officer
Daniel Tsegai before an international audience. “We already see
impacts in highly productive and populated parts of the
developed world like California, Spain, and Australia.”
There is a critical need to improve and expand precipitation
forecasting in the Western United States. Access to reliable
forecasts at timeframes longer than seven days is long overdue,
especially in the West, where conditions can rapidly swing
between extreme droughts and floods. Advancing and
updating our precipitation forecasts is beyond necessary for
our decision-makers, water agencies, agricultural producers,
energy suppliers, tribes and others, so they can take accurate
and necessary mitigation actions and put contingency plans in
place to protect our cities and our local communities. The
National Oceanic and Atmospheric Administration (NOAA) is
responsible for weather forecasts, provided through the
National Weather Service (NWS) and weather and climate research
produced by the Office of Atmospheric Research. Together, these
agencies support the National Weather Service’s goal of having
a “weather-ready nation,” preparing communities for extreme
weather, water, and climate events. -Written by Rep. Grace Napolitano, who
serves as the representative for California’s
31st District.
The fate of the nation’s first outdoor experiment of the
potential to limit global warming by altering clouds will be
determined this week by a handful of local officials in the San
Francisco Bay Area. But before the city council of Alameda,
elected by a community of 77,000 people, decides on whether to
allow the resumption of the internationally significant
research, it will discuss replacing the roof of a senior center
and other municipal issues. The consideration of the marine
cloud brightening study — official, agenda item “7-B” — stands
to be one of the first consequential public hearings on solar
geoengineering in the nation. The unusual situation set to play
out Tuesday night illustrates just how hard it is to test
technologies that might be used in the future to brighten
clouds or spray aerosols in the stratosphere — promising but
ethically fraught ways to turn down the planet’s thermostat by
reflecting sunlight back into space.
California officials are cheering Mexican President-elect
Claudia Sheinbaum’s victory as one for the California climate,
too. “Having an engineer whose background is working on
climate, it’s a big deal,” said Assemblymember Eduardo Garcia,
a Democrat representing California’s inland border region who
was in Mexico City with Sheinbaum’s team on Sunday to witness
her landslide victory. … California politicians already
enjoy close relationships with their Mexican counterparts and
have agreements in place to work on a host of climate issues,
including drought, land conservation, recycling and
cross-border truck emissions. … Josué Medellín-Azuara,
an environmental engineering professor at the University of
California, Merced said he was hoping for more collaboration on
water infrastructure and drought resiliency in particular.
Marin County’s major water providers have raised rebates for
rainwater catchment systems because of county funding. The
Marin Municipal Water District and the North Marin Water
District are offering customers with the systems rebates of 75
cents per gallon of water — 25 cents more than before. The
offer is supported by $20,000 in funding from the Marin County
Stormwater Pollution Prevention Program. The grant marks a
collaboration between Marin County and the water utilities to
encourage residents to save water. Collecting rainwater to use
for irrigation also helps protect the area from potential
flooding during storms, and prevents pollutants collected
through water runoff from entering bodies of water.
Amid extreme drought affecting Rio Grande tributaries, Mexico
is struggling to make water deliveries to Texas as required by
an 80-year old treaty. Martha Pskowski is a reporter with
Inside Climate News and spoke with Living on Earth’s Paloma
Beltran about how the situation is linked to climate change and
farmer livelihoods in both the US and Mexico.
Known for its glowing swaths of yellow, orange and red, the
U.S. Drought Monitor has warned farmers, residents and
officials throughout the nation of impending water scarcity
every week since 1999. Backed by data on soil moisture,
temperature, snow cover, meltwater runoff, reservoir levels and
more, the map has become an essential instrument for
determining the outlook of water supplies, declaring drought
emergencies and deciding where and when government aid should
be distributed, among other things. But this critical
diagnostic tool is also struggling to keep pace with climate
change as longer and more persistent dry spells plague the
American West and take an increasing toll on groundwater
reserves and the Colorado River, according to a recent study
published in the journal AGU Advances. One problem, researchers
say, is that the monitor was launched just as one of the driest
periods in the history of the Southwest began, and it has never
been adjusted for the region’s growing aridity.
Ukiah Fire Chief Doug Hutchison knew what kind of hassle the
city was getting into by acquiring some 763 acres of overgrown,
fire-starved forest on the city’s western edge—but it seemed
worth it. There, Doolin Creek’s two forks merge and run through
a steep canyon, eventually heading straight through the city
and emptying into the Russian River. Steelhead trout, which
swim most of the way up the Russian River’s 110 miles to spawn
in its tributaries, and year-round resident native fishes like
sculpins and roaches, are kept cool by big trees shading the
creek. California nutmeg, fragrant like sandalwood, has been
spotted here, and spiky chinquapin. Also, the manzanita and
chamise are so thick in places that it’s hard to walk through.
If a big hot fire rolled through here, it would be very bad for
the wildlife, the forest, and the community. The city has taken
on the property to mitigate those fire risks and protect the
watershed.
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.”

The Layperson’s Guide to the Colorado River Basin introduces the
1,450-mile river that sustains 40 million people and millions of
acres of farmland spanning seven states and parts of northern
Mexico.
The 28-page primer explains how the river’s water is shared and
managed as the Southwest transitions to a hotter and drier
climate.
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.
After more than two decades of
drought, water utilities serving the largest urban regions in the
arid Southwest are embracing a drought-proof source of drinking
water long considered a supply of last resort: purified sewage.
Water supplies have tightened to the point that Phoenix and the
water supplier for 19 million Southern California residents are
racing to adopt an expensive technology called “direct potable
reuse” or “advanced purification” to reduce their reliance on
imported water from the dwindling Colorado River.
The climate-driven shrinking of the
Colorado River is expanding the influence of Native American
tribes over how the river’s flows are divided among cities, farms
and reservations across the Southwest.
The tribes are seeing the value of their largely unused river
water entitlements rise as the Colorado dwindles, and they are
gaining seats they’ve never had at the water bargaining table as
government agencies try to redress a legacy of exclusion.
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.
Every five years the California Department of Water Resources
updates its strategic plan for managing the state’s water
resources, as required by state law.
The California Water Plan, or Bulletin 160, projects the
status and trends of the state’s water supplies and demands
under a range of future scenarios.
A new but little-known change in
California law designating aquifers as “natural infrastructure”
promises to unleash a flood of public funding for projects that
increase the state’s supply of groundwater.
The change is buried in a sweeping state budget-related law,
enacted in July, that also makes it easier for property owners
and water managers to divert floodwater for storage underground.
A 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.
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.
This tour explored the lower Colorado River firsthand 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 some 40 million people in the Southwest across seven states, 30 tribal nations 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.

It 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.
This special Foundation water tour journeyed along the Eastern Sierra from the Truckee River to Mono Lake, through the Owens Valley and into the Mojave Desert to explore a major source of water for Southern California, this year’s snowpack and challenges for towns, farms and the environment.
Growing up in the shadow of the
Rocky Mountains, Andrew Schwartz never missed an opportunity to
play in – or study – a Colorado snowstorm. During major
blizzards, he would traipse out into the icy wind and heavy
drifts of snow pretending to be a scientist researching in

Decades later, still armed with an obsession for extreme weather,
Schwartz has landed in one of the snowiest places in the West,
leading a research lab whose mission is to give California water
managers instant information on the depth and quality of snow
draping the slopes of the Sierra Nevada.
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.
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?

With 25 years of experience working
on the Colorado River, Chuck Cullom is used to responding to
myriad challenges that arise on the vital lifeline that seven
states, more than two dozen tribes and the country of Mexico
depend on for water. But this summer problems on the
drought-stressed river are piling up at a dizzying pace:
Reservoirs plummeting to record low levels, whether Hoover Dam
and Glen Canyon Dam can continue to release water and produce
hydropower, unprecedented water cuts and predatory smallmouth
bass threatening native fish species in the Grand Canyon.
“Holy buckets, Batman!,” said Cullom, executive director of the
Upper Colorado River Commission. “I mean, it’s just on and on and
on.”
This printed issue of Western Water explores some of the major
challenges facing Colorado River stakeholders: preparing for
climate change, forging U.S.-Mexico water supply solutions and
dealing with continued growth in the basins states. Much of the
content for this issue of Western Water came from the in-depth
panel discussions at the September 2009 Colorado River Symposium.
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.
Managers of California’s most
overdrawn aquifers were given a monumental task under the state’s
landmark Sustainable Groundwater Management Act: Craft viable,
detailed plans on a 20-year timeline to bring their beleaguered
basins into balance. It was a task that required more than 250
newly formed local groundwater agencies – many of them in the
drought-stressed San Joaquin Valley – to set up shop, gather
data, hear from the public and collaborate with neighbors on
multiple complex plans, often covering just portions of a
groundwater basin.
Momentum is building for a unique
interstate deal that aims to transform wastewater from Southern
California homes and business into relief for the stressed
Colorado River. The collaborative effort to add resiliency to a
river suffering from overuse, drought and climate change is being
shaped across state lines by some of the West’s largest water
agencies.
This tour explored the lower Colorado River firsthand 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 some 40 million people in the Southwest across seven states, 30 tribal nations 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 tour 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.
Climate scientist Brad Udall calls
himself the skunk in the room when it comes to the Colorado
River. Armed with a deck of PowerPoint slides and charts that
highlight the Colorado River’s worsening math, the Colorado State
University scientist offers a grim assessment of the river’s
future: Runoff from the river’s headwaters is declining, less
water is flowing into Lake Powell – the key reservoir near the
Arizona-Utah border – and at the same time, more water is being
released from the reservoir than it can sustainably provide.

For more than 20 years, Tanya
Trujillo has been immersed in the many challenges of the Colorado
River, the drought-stressed lifeline for 40 million people from
Denver to Los Angeles and the source of irrigation water for more
than 5 million acres of winter lettuce, supermarket melons and
other crops.
Trujillo has experience working in both the Upper and Lower
Basins of the Colorado River, basins that split the river’s water
evenly but are sometimes at odds with each other. She was a
lawyer for the state of New Mexico, one of four states in the
Upper Colorado River Basin, when key operating guidelines for
sharing shortages on the river were negotiated in 2007. She later
worked as executive director for the Colorado River Board of
California, exposing her to the different perspectives and
challenges facing California and the other states in the river’s
Lower Basin.
Water as a renewable resource is depicted in this 18×24 inch

This page is a resource for all things drought – where you
can find real-time reservoir levels, drought severity
maps, special reports, a newsfeed of current
developments on the drought that began in 2020 and general
background on droughts in California and the West, as well as
answers to common drought questions and tips for how you can save
water at home.
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.
Las Vegas, known for its searing summertime heat and glitzy casino fountains, is projected to get even hotter in the coming years as climate change intensifies. As temperatures rise, possibly as much as 10 degrees by end of the century, according to some models, water demand for the desert community is expected to spike. That is not good news in a fast-growing region that depends largely on a limited supply of water from an already drought-stressed Colorado River.
When you oversee the largest
supplier of treated water in the United States, you tend to think
big.
Jeff Kightlinger, general manager of the Metropolitan Water
District of Southern California for the last 15 years, has
focused on diversifying his agency’s water supply and building
security through investment. That means looking beyond MWD’s
borders to ensure the reliable delivery of water to two-thirds of
California’s population.
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.
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.
Across a sprawling corner of southern Tulare County snug against the Sierra Nevada, a bounty of navel oranges, grapes, pistachios, hay and other crops sprout from the loam and clay of the San Joaquin Valley. Groundwater helps keep these orchards, vineyards and fields vibrant and supports a multibillion-dollar agricultural economy across the valley. But that bounty has come at a price. Overpumping of groundwater has depleted aquifers, dried up household wells and degraded ecosystems.
Twenty years ago, the Colorado River
Basin’s hydrology began tumbling into a historically bad stretch.
The weather turned persistently dry. Water levels in the system’s
anchor reservoirs of Lake Powell and Lake Mead plummeted. A river
system relied upon by nearly 40 million people, farms and
ecosystems across the West was in trouble. And there was no guide
on how to respond.
Practically every drop of water that flows through the meadows, canyons and plains of the Colorado River Basin has reams of science attached to it. Snowpack, streamflow and tree ring data all influence the crucial decisions that guide water management of the iconic Western river every day.
Dizzying in its scope, detail and complexity, the scientific information on the Basin’s climate and hydrology has been largely scattered in hundreds of studies and reports. Some studies may conflict with others, or at least appear to. That’s problematic for a river that’s a lifeline for 40 million people and more than 4 million acres of irrigated farmland.
Sprawled across a desert expanse
along the Utah-Arizona border, Lake Powell’s nearly 100-foot high
bathtub ring etched on its sandstone walls belie the challenges
of a major Colorado River reservoir at less than half-full. How
those challenges play out as demand grows for the river’s water
amid a changing climate is fueling simmering questions about
Powell’s future.
This event 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.
The Colorado River is arguably one
of the hardest working rivers on the planet, supplying water to
40 million people and a large agricultural economy in the West.
But it’s under duress from two decades of drought and decisions
made about its management will have exceptional ramifications for
the future, especially as impacts from climate change are felt.
Every other year we hold an
invitation-only Colorado River Symposium attended by various
stakeholders from across the seven Western states and Mexico that
rely on the iconic river. We host this three-day event in Santa
Fe, N.M., where the 1922 Colorado River Compact was signed, as
part of our mission to catalyze critical conversations to build
bridges and inform collaborative decision-making.
Many of California’s watersheds are
notoriously flashy – swerving from below-average flows to jarring
flood conditions in quick order. The state needs all the water it
can get from storms, but current flood management guidelines are
strict and unyielding, requiring reservoirs to dump water each
winter to make space for flood flows that may not come.
However, new tools and operating methods are emerging that could
lead the way to a redefined system that improves both water
supply and flood protection capabilities.
California is chock full of rivers and creeks, yet the state’s network of stream gauges has significant gaps that limit real-time tracking of how much water is flowing downstream, information that is vital for flood protection, forecasting water supplies and knowing what the future might bring.
That network of stream gauges got a big boost Sept. 30 with the signing of SB 19. Authored by Sen. Bill Dodd (D-Napa), the law requires the state to develop a stream gauge deployment plan, focusing on reactivating existing gauges that have been offline for lack of funding and other reasons. Nearly half of California’s stream gauges are dormant.
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.
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.
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
New to this year’s slate of water
tours, our Edge of
Drought Tour Aug. 27-29 will venture into the Santa
Barbara area to learn about the challenges of limited local
surface and groundwater supplies and the solutions being
implemented to address them.
Despite Santa Barbara County’s decision to lift a drought
emergency declaration after this winter’s storms replenished
local reservoirs, the region’s hydrologic recovery often has
lagged behind much of the rest of the state.
On average, more than 60 percent of
California’s developed water supply originates in the Sierra
Nevada and the southern spur of the Cascade Range. Our water
supply is largely dependent on the health of our Sierra forests,
which are suffering from ecosystem degradation, drought,
wildfires and widespread tree mortality.
This tour ventured into the Sierra to examine water issues
that happen upstream but have dramatic impacts downstream and
throughout the state.
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.
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
This tour journeyed through a scenic landscape and
explored an area of California dealing with
persistent threats to its water supply and quality. Along
the way, we learned about solutions that were being
implemented.
Although Santa Barbara County had lifted its drought
emergency declaration after the 2019 storms replenished
local reservoirs, the region’s hydrologic recovery has often
lagged behind much of the rest of the state. It is a region
particularly prone to drought, wildfires and mudslides.
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.
For the bulk of her career, Jayne
Harkins has devoted her energy to issues associated with the
management of the Colorado River, both with the U.S. Bureau of
Reclamation and with the Colorado River Commission of Nevada.
Now her career is taking a different direction. Harkins, 58, was
appointed by President Trump last August to take the helm of the
United States section of the U.S.-Mexico agency that oversees
myriad water matters between the two countries as they seek to
sustainably manage the supply and water quality of the Colorado
River, including its once-thriving Delta in Mexico, and other
rivers the two countries share. She is the first woman to be
named the U.S. Commissioner of the International Boundary and
Water Commission for either the United States or Mexico in the
commission’s 129-year history.
This tour 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 is the focus of this tour.

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 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.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
As stakeholders labor to nail down
effective and durable drought contingency plans for the Colorado
River Basin, they face a stark reality: Scientific research is
increasingly pointing to even drier, more challenging times
ahead.
The latest sobering assessment landed the day after Thanksgiving,
when U.S. Global Change Research Program’s Fourth National Climate
Assessment concluded that Earth’s climate is changing rapidly
compared to the pace of natural variations that have occurred
throughout its history, with greenhouse gas emissions largely the
cause.
In the universe of California water, Tim Quinn is a professor emeritus. Quinn has seen — and been a key player in — a lot of major California water issues since he began his water career 40 years ago as a young economist with the Rand Corporation, then later as deputy general manager with the Metropolitan Water District of Southern California, and finally as executive director of the Association of California Water Agencies. In December, the 66-year-old will retire from ACWA.
Just because El Niño may be lurking
off in the tropical Pacific, does that really offer much of a
clue about what kind of rainy season California can expect in
Water Year 2019?
Will a river of storms pound the state, swelling streams and
packing the mountains with deep layers of heavy snow much like
the exceptionally wet 2017 Water Year (Oct. 1, 2016 to Sept. 30,
2017)? Or will this winter sputter along like last winter,
leaving California with a second dry year and the possibility of
another potential drought? What can reliably be said about the
prospects for Water Year 2019?
At Water Year
2019: Feast or Famine?, a one-day event on Dec. 5 in Irvine,
water managers and anyone else interested in this topic will
learn about what is and isn’t known about forecasting
California’s winter precipitation weeks to months ahead, the
skill of present forecasts and ongoing research to develop
predictive ability.
“Dry, hot and on fire” is how the
California Department of Water Resources described Water Year
2018 in a recent report.
Water Year 2018 – from Oct. 1, 2017 to Sept. 30, 2018 -
marked a return to dry conditions statewide following an
exceptionally wet 2017, according to DWR’s Water
Year 2018 report. But 2017 was exceptional as all but two of
the water years in the past decade experienced drought.
Was Water Year 2018 simply a single dry year or does it
signal the beginning of another drought? And what can
reliably be said about the prospects for Water Year 2019? Does El
Niño really mean anything for California or is it all washed up
as a predictor?

There’s going to be a new governor
in California next year – and a host of challenges both old and
new involving the state’s most vital natural resource, water.
So what should be the next governor’s water priorities?
That was one of the questions put to more than 150 participants
during a wrap-up session at the end of the Water Education
Foundation’s Sept. 20 Water Summit in Sacramento.
People in California and the
Southwest are getting stingier with water, a story that’s told by
the acre-foot.
For years, water use has generally been described in terms of
acre-foot per a certain number of households, keying off the
image of an acre-foot as a football field a foot deep in water.
The long-time rule of thumb: One acre-foot of water would supply
the indoor and outdoor needs of two typical urban households for
a year.
The Colorado River Basin is more
than likely headed to unprecedented shortage in 2020 that could
force supply cuts to some states, but work is “furiously”
underway to reduce the risk and avert a crisis, Bureau of
Reclamation Commissioner Brenda Burman told an audience of
California water industry people.
During a keynote address at the Water Education Foundation’s
Sept. 20 Water Summit in Sacramento, Burman said there is
opportunity for Colorado River Basin states to control their
destiny, but acknowledged that in water, there are no guarantees
that agreement can be reached.
Amy Haas recently became the first non-engineer and the first woman to serve as executive director of the Upper Colorado River Commission in its 70-year history, putting her smack in the center of a host of daunting challenges facing the Upper Colorado River Basin.
Yet those challenges will be quite familiar to Haas, an attorney who for the past year has served as deputy director and general counsel of the commission. (She replaced longtime Executive Director Don Ostler). She has a long history of working within interstate Colorado River governance, including representing New Mexico as its Upper Colorado River commissioner and playing a central role in the negotiation of the recently signed U.S.-Mexico agreement known as Minute 323.
Nowhere is the domino effect in
Western water policy played out more than on the Colorado River,
and specifically when it involves the Lower Basin states of
California, Nevada and Arizona. We are seeing that play out now
as the three states strive to forge a Drought Contingency Plan.
Yet that plan can’t be finalized until Arizona finds a unifying
voice between its major water players, an effort you can read
more about in the latest in-depth article of Western Water.
Even then, there are some issues to resolve just within
California.
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.
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.
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.
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 2012-2016 drought
revealed vulnerabilities for water users throughout the state,
and the long-term record suggests more challenges may lie ahead.
An April 19
workshop in San Pedro will highlight new information about
drought durations in Southern California watersheds dating
back centuries.
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.
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.
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.
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.
Sixty percent of California’s developed water supply
originates high in the Sierra Nevada mountains. Our water
supply is largely dependent on the health of our Sierra forests,
which are suffering from ecosystem degradation, drought,
wildfires and widespread tree mortality.
This three-day, two-night tour 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 is the focus of this tour.

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.”
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).
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.
A hydrograph illustrates a type of activity of water during a
specific time frame. Salinity and acidity are sometimes measured,
but the most common types
are stage and discharge hydrographs. These graphs show how
surface water flow responds to fluxes in precipitation.
California is no stranger to drought. 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.

and provide answers below. Simply click on the question for the

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.

This free briefing sponsored by the Department of Water Resources
and the Water Education Foundation will discuss forecasts of
water project operations in the coming year.
Water year 2016 has officially begun, and all eyes are on the
weather and the potential runoff. But even if the projected heavy
El Niño becomes reality, the state’s drought-impacted reservoirs
are still a major concern.
This issue examines the impacts of California’s epic
drought, especially related to water supplies for San Joaquin
Valley rural communities and farmland.
Drought doesn’t instantly ravage
the way flooding does. It advances at a steady, determined pace,
building and spreading during several years. Fields wither,
reservoirs drop to dangerously low levels and the memory of what
constitutes a normal water supply becomes more distant.

Introduction
California’s severe drought has put its water rights system under
scrutiny, raising the question whether a complete overhaul is
necessary to better allocate water use.
This 2-day, 1-night tour traveled through the San Joaquin Valley
to explore the impacts of California’s unprecedented four-year
drought on the nation’s breadbasket and what steps are being
taken to avert disaster.
This 3-day, 2-night tour followed the course of the
lower Colorado River through Nevada, Arizona and California, and
included a private tour of Hoover Dam.
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.
Living in the semi-arid, Mediterranean climate of California,
drought always lingers on the horizon. People believe they are
ready to face the next dry period, then conditions arrive testing
whether that is the case.

This 25-minute documentary-style DVD, developed in partnership
with the California Department of Water Resources, provides an
excellent overview of climate change and how it is already
affecting California. The DVD also explains what scientists
anticipate in the future related to sea level rise and
precipitation/runoff changes and explores the efforts that are
underway to plan and adapt to climate.
Many Californians don’t realize that when they turn on the
faucet, the water that flows out could come from a source close
to home or one hundreds of miles away. Most people take their
water for granted; not thinking about the elaborate systems and
testing that go into delivering clean, plentiful water to
households throughout the state. Where drinking water comes from,
how it’s treated, and what people can do to protect its quality
are highlighted in this 2007 PBS documentary narrated by actress
Wendie Malick.
A 30-minute version of the 2007 PBS documentary Drinking Water:
Quenching the Public Thirst. This DVD is ideal for showing at
community forums and speaking engagements to help the public

Western states that share the Colorado River with Mexico. The
Colorado River supplies water to nearly 40 million people in
Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming
and Mexico. Text on this beautiful, 24×36-inch map, which is
suitable for framing, explains the river’s apportionment, history
and the need to adapt its management for urban growth and
expected climate change impacts.
It seems not a matter of if but when seawater desalination will
fulfill the promise of providing parts of California with a
reliable, drought-proof source of water. With a continuing
drought and uncertain water deliveries, the state is in the grip
of a full-on water crisis, and there are many people who see
desalination as a way to provide some relief to areas struggling
to maintain an adequate water supply.
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.
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).

projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
30-minute DVD that traces the history of the U.S. Bureau of
Reclamation and its role in the development of the West. Includes
extensive historic footage of farming and the construction of
dams and other water projects, and discusses historic and modern
day issues.
Just before summer officially began in June, Gov. Arnold
Schwarzenegger publicly proclaimed what many people already knew:
California is in a drought. Consecutive years of sub par rainfall
coupled with a 2008 snowpack that literally dried up and blew
away before it could turn into runoff forced the issuance of the
state’s first drought declaration since 1991.
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.
Water truly has shaped California into the great state it is
today. And if it is water that made California great, it’s the
fight over – and with – water that also makes it so critically
important. In efforts to remap California’s circulatory system,
there have been some critical events that had a profound impact
on California’s water history. These turning points not only
forced a re-evaluation of water, but continue to impact the lives
of every Californian. This 2005 PBS documentary offers a
historical and current look at the major water issues that shaped
the state we know today. Includes a 12-page viewer’s guide with
background information, historic timeline and a teacher’s lesson.
