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.
Deadly heat in the Southwest. Hot-tub temperatures in the
Atlantic Ocean. Sweltering conditions in Europe, Asia and South
America. That 2023 was Earth’s hottest year on record was in
some ways no surprise. For decades, scientists have been
sounding the alarm about rapidly rising temperatures driven by
humanity’s relentless burning of fossil fuels. But last year’s
sudden spike in global temperatures blew far beyond what
statistical climate models had predicted, leading one noted
climate scientist to warn that the world may be entering
“uncharted territory.” … [R]esearchers are scrambling to
explain why 2023 was so anomalously hot. Many theories have
been proposed, but “as yet, no combination of them has been
able to reconcile our theories with what has happened,” Schmidt
wrote.
The Mid-Kings River Groundwater Sustainability Agency is
looking to impose a pumping fee of nearly $100 per
acre-foot. Mid-Kings River GSA is comprised of the Kings
County Water District, the City of Hanford and Kings
County. The big picture: The GSA is proposing a
pumping fee maximum of $95 per acre-foot. This comes after
the State views that the region has not made enough progress
through the Sustainable Groundwater Management Act
(SGMA). The state wants agriculture and industrial water
pumpers to cut back or pay to mitigate the impacts on
other users. The state could move to put the subbasin in
probation if it does not feel confident in local groundwater
management, and could completely take over operations in 2025.
Does the public sector need the private sector’s help to
address the freshwater crisis? That’s the controversial thesis
of Stanford law and environmental social sciences professor
Barton “Buzz” Thompson’s provocatively titled new book: Liquid
Asset: How Business and Government Can Partner to Solve the
Freshwater Crisis. (Buzz is also a member of the PPIC Water
Policy Center’s research network.) We sat down with him to hear
more. … The private sector is already involved in water in
many ways, some more controversial than others. … We
think of the Sustainable Groundwater Management Act (SGMA) as a
public program, and it is. The legislature passed the law, and
public agencies are implementing it. But if you look carefully,
you’ll see private handprints all over SGMA’s success.
California farmers could save massive amounts of water if they
planted less thirsty — but also less lucrative — crops such as
grains and hay instead of almonds and alfalfa, according to new
research by scientists who used remote sensing and artificial
intelligence. Such a seismic shift in the nation’s most
productive agricultural state could cut consumption by roughly
93%, researchers with UC Santa Barbara and the NASA Jet
Propulsion Laboratory reported Monday. But Anna Boser, the
study’s lead author, acknowledged that replacing all of
California’s water-intensive crops with the least-intensive
ones is an unrealistic economic scenario. … In a
less-extreme scenario, Boser and her colleagues reported that
fallowing 5% of fields with the most water-intensive crops
could cut water consumption by more than 9%, according to
the study, published in the journal Nature Communications.
It’s the second straight year of above-average rain and snow in
California, amid the state’s driest period in 1,200 years. The
respite from drought is certainly welcome, despite flooding,
mudslides and associated miseries. Now meteorologists and
oceanographers are watching possible La Niña conditions develop
in the Pacific, perhaps signaling a return to drier times. It’s
an appropriate time to take stock — of how we weathered the
last two winters, what we’ve learned and what’s ahead.
… It’s also important to note that California got a
scary dose of climate change reality early in the winter when
all that precipitation failed to turn into Sierra snowpack. It
does us little good to get lots of rain or even snow if the
weather is too warm to permit snow accumulation on the slopes.
The annual snowpack‘s slow spring-and-summer melt has
historically been the primary source of water for California
cities and farm fields.
Water shortages are becoming a way of life in cities across the
globe — Los Angeles; Cape Town, South Africa; Jakarta,
Indonesia; and many more — as climate change worsens and
authorities often pipe in water from ever-more-distant sources.
“Water sources are depleted around the world,” said Victoria
Beard, a professor of city and regional planning at Cornell
University. “Every year, more cities will face ‘Day Zero,’ with
no water in their piped systems.” Mexico City — founded by the
Aztecs on an island amid lakes, with a rainy season that
brought torrents and flooding — might have been an exception.
For decades, the focus has been getting rid of water, not
capturing it. But a grim convergence of factors — including
runaway growth, official indifference, faulty infrastructure,
rising temperatures and reduced rainfall — have left this
mega-city at a tipping point after years of mostly unheeded
warnings.
NASA and the German Space Agency at DLR (German Aerospace
Center) have agreed to jointly build, launch, and operate a
pair of spacecraft that will yield insights into how Earth’s
water, ice, and land masses are shifting by measuring monthly
changes in the planet’s gravity field. Tracking large-scale
mass changes – showing when and where water moves within and
between the atmosphere, oceans, underground aquifers, and ice
sheets – provides a view into Earth’s water cycle, including
changes in response to drivers like climate change.
A network of artificial streams is teaching scientists how
California’s mountain waterways — and the ecosystems that
depend on them — may be impacted by a warmer, drier climate.
Over the next century, climate change is projected to bring
less snowfall to the Sierra Nevada. … In a new study,
University of California, Berkeley, researchers used a series
of nine artificial stream channels off Convict Creek in Mammoth
Lakes, California, to mimic the behavior of headwater streams
under present-day conditions and future climate change
scenarios.
Can Texas, New Mexico, and Colorado agree to a new
apportionment of the Rio Grande’s waters without the U.S.
government’s approval? The Supreme Court of the United States
is set to hear a case next week that may affect access to water
for millions of Americans — and set a precedent that could
impact millions more, as increased usage and climate change
further strain supply of the precious resource. … If
[the court sides with the states], the government might be
understood to have less weight to throw around in other
negotiations, such as the one that is also happening about the
Colorado River.
In early February 2024 the Mountain Counties Water Resources
Association adopted new forest management principles with the
goal of solving the ongoing problem and severe effects of
California’s mega wildfires. “Over 100 years of
suppressing wildfires and changing climate have produced
overgrown forests and catastrophic mega wildfires that are
impacting communities, degrading California’s headwaters’ water
quality, water infrastructure and forest resources in Sierra
Nevada watersheds, (ultimately) creating a toxic smoke health
hazard throughout the state,” MCWRA’s website
reads. “These severe mega wildfires release tons of
greenhouse gases and eliminate the ability of forests to absorb
and store atmospheric carbon,” the website continues.
The United States suffers the world’s second-highest toll from
major weather disasters, according to a new analysis — even
when numbers are adjusted for the country’s wealth. The report
released late last month by Zurich-based reinsurance giant
Swiss Re, which analyzed the vulnerability and damages of 36
different countries, suggests that weather disasters may become
a heavy drag on the U.S. economy — especially as insurers
increasingly pull out of hazardous areas. Those disasters are
driving up insurance rates, compounding inflation and adding to
Americans’ high cost of living. … Some insurers have
stopped offering home insurance policies in California, which
has seen numerous large wildfires in the past few years.
The Biden administration will be allocating more than $120
million to tribal governments to fight the impacts of climate
change, the Department of the Interior announced Thursday. The
funding is designed to help tribal nations adapt to climate
threats, including relocating infrastructure. Indigenous
peoples in the U.S. are among the communities most affected by
severe climate-related environmental threats, which have
already negatively impacted water resources, ecosystems and
traditional food sources in Native communities in every corner
of the U.S. “As these communities face the increasing
threat of rising seas, coastal erosion, storm surges, raging
wildfires and devastation from other extreme weather events,
our focus must be on bolstering climate resilience …”
Interior Secretary Deb Haaland, a member of the Pueblo of
Laguna, said in a Wednesday press briefing.
Sacramento and cities across California caught a break from the
state’s water regulator this week after the agency faced
criticism that its water conservation rules were too
complicated and costly to meet. Regulators at the State Water
Resources Control Board proposed new conservation rules Tuesday
that would ease water savings requirements for urban water
suppliers and will ultimately lead to less long-term water
savings than initially planned. Under the new rules, the city
of Sacramento would have to cut its overall water use by 9% by
2035 and 14% by 2040, far less than an initial proposal that
would have required it to cut back water use by 13% by 2030 and
18% by 2035.
Climate change is driving up the thirst of crops
significantly in California’s San Joaquin Valley, new research
shows, adding to the critical water challenges faced by one of
the world’s leading agricultural regions. The total water
demand of orchards, vineyards and row crops in the area is up
4.4% over the past decade compared with the prior 30 years
because of hotter, drier conditions, and it’s likely to
continue growing, according to a federally funded study
published this week. In 2021, the water demand of crops was up
an astonishing 12.3%, the study shows. While the warming
atmosphere has long been known to dry out plants and soil, the
new research identifies the impact specific to the
San Joaquin Valley.
Giant sequoia trees, imported to the UK 160 years ago, are
flourishing despite the dramatically different climate to their
native California, a new study has found. The huge trees, which
are declining in numbers in California due to increasing heat,
are now adapting well to the UK’s climate and growing taller, a
study conducted by UCL researchers says. “The growth here
in the UK seems to be suited to our wetter climate, so there’s
far less chance of water stress here than in the Sierras in
California,” lead author of the study and professor of
geogrpahy, Mat Disney, told The Independent.
California citrus farmers are finding ways to adapt to the
changing landscape, as the challenges of this production year
come to light. Amid the harvest of California navels,
mandarins, and other specialty varieties, two industry leaders
share their perspectives on the prospects of the industry.
… Jim Phillips, President and CEO of Sunkist, expressed
similar concerns regarding production but also emphasized the
current state of affairs regarding the Sustainable Groundwater
Management Act (SGMA). California citrus farmers need the
support of the legislature regarding water access, as the issue
is outpacing almost every other concern for growers, said
Phillips. Both Bates and Phillips noted that the
substantial amount of rainfall and snowpack over the past two
winters are supporting growers in the fight for water access.
Across the parched West, there are signs the region’s
decades-long population and housing boom is confronting the
realities of dwindling water supplies. These have come in
recent months from court rulings and executive edicts alike, as
states crack down on the potential for new users to draw from
already oversubscribed aquifers and surface waters. The
skeleton of a would-be subdivision outside Las Vegas
illustrates the coming constraints, stymied by a lack of water
to support the new community. Water shortages also forced
difficult decisions in other places, such as new restrictions
in the Phoenix suburbs and a Utah town that halted all new
construction for more than two years until it could secure a
new well.
Drought or no drought, California water regulators are pushing
ahead with a new conservation policy that could force some
communities to cut water use upward of 30% permanently — though
on more lenient terms than originally proposed. The
first-of-its-kind regulation is intended to help the state
confront chronic water shortages as climate change makes for
hotter, drier weather. The initial draft of the regulation,
released last year, was widely criticized for asking roughly
400 cities and water agencies to cut back too much too quickly.
The cost of compliance was also a concern. Acknowledging the
burden, the State Water Resources Control Board on Tuesday
unveiled a revised set of rules that would allow some
communities to use more water than originally planned as well
as extend deadlines for meeting the conservation mandates.
California has set ambitious climate goals, including phasing
out the use of fossil fuels and becoming carbon neutral by
2045. Our guest today is here to talk about the role nature can
play in meeting those goals. Laurie Wayburn is the co-founder
and president of the Pacific Forest Trust and the chair of the
California Natural and Working Lands Expert Advisory Committee.
She was also the lead author of a recent report suggesting the
state should invest “as much in nature-based climate solutions
as it has in clean energy and transportation.” With proper
forest management, California could capture 400 million tons of
carbon each year, lower wildfire risk and vastly improve flood
protection in the state.
Monday marked a key cutoff time by which Colorado River states
had been tasked with proposing a consensus-based plant for
long-term water conservation in the overtaxed system. But
with the arrival of that deadline, set by the Department of the
Interior’s Bureau of Reclamation, no such agreement was on the
table. Instead, the river system’s two main contingents — the
Upper and Lower basins — submitted their own competing
plans. The proposals pertained to an upcoming update of
the rules — known as the 2007 Interim Guidelines for Lower
Basin Shortages — that govern where, when and how much the
seven basin states must conserve water from the 1,450-mile
river.
California’s fishing industry is bracing for another bad year
as federal managers today announced plans to heavily restrict
or prohibit salmon fishing again, after cancelling the entire
season last year. The Pacific Fishery Management Council
today released a series of options that are under
consideration, all of which either ban commercial and
recreational salmon fishing in the ocean off California or
shorten the season and set strict catch limits. The council’s
decision is expected next month; the commercial season
typically begins in May and ends in October. … [P]opulations
are now a fraction of what they once were — dams have
blocked vital habitat, while droughts and water diversions have
driven down flows and increased temperatures, killing large
numbers of salmon eggs and young fish.
Ahead of a deadline next week, the seven states that share the
Colorado River have revealed competing plans for how the river
should be managed in the future. They’re split into two
factions, with the Upper Basin states of Colorado, New Mexico,
Utah, and Wyoming on one side, and their Lower Basin
counterparts—California, Arizona and Nevada—on the other. Those
two camps have been at odds over water management many times
over the past century. Now, with climate change shrinking the
Colorado River’s supply, they’re under intense pressure to rein
in demand. While the current guidelines for sharing the
river don’t expire until 2026, the Biden Administration set a
mid-March deadline for proposals for new guideline, in part
because the upcoming election in November could bring a change
of presidential administration that could complicate the
implementation of new rules.
California officials are preparing new urban water conservation
rules intended to help the state adapt to a drier future caused
by climate change. In reality, the proposed restrictions are so
great they could actually harm those adaptation efforts by
sacrificing the tree canopy we have nurtured in our cities for
generations. The “Making Conservation a California Way of Life”
rule package, proposed by the State Water Resources Control
Board, sets conservation targets unique to each urban water
agency in the state. While conserving each and every year makes
sense, so must the restrictions. A recent report by the
non-partisan Legislative Analyst’s Office found big flaws in
the Water Board’s approach, describing the proposal as overly
complex, expensive and unrealistic, with potential water
savings amounting to a mere drop in the bucket statewide. -Written by Jim Peifer, executive director of the
Sacramento Regional Water Authority; and Victoria
Vasquez, grants and public policy manager
for California ReLeaf, which works to protect, enhance and
grow California’s urban and community forests.
What a difference a month makes. There has been some
hand-wringing this winter regarding California’s 2024 water
outlook, especially in the southern mountains and the Kern
River Watershed. But new reports are pointing toward a much
more favorable water year, including in the Kern River Basin,
and by extension, Isabella Lake storage.
Arizona officials said a Saudi-owned company they targeted over
its use of groundwater to grow forage crops is moving its
farming operation out of a valley in the Southwestern state’s
rural west. Gov. Katie Hobbs and the Arizona State Land
Department announced late Thursday that Fondomonte Arizona is
officially no longer pumping water in the Butler Valley
groundwater basin. Some residents of La Paz County had
complained that the company’s pumping was threatening their
wells. A statement by Hobbs says an on-site inspection had
confirmed that Fondomonte was moving to vacate the property.
Fondomonte has several other farms elsewhere in Arizona that
are not affected by the decision.
In 2012, one of the driest years in Colorado in recent memory,
the Crystal River practically dried up. Ken Neubecker, a
now-retired Colorado projects director at environmental group
American Rivers and former member of the Pitkin County Healthy
Rivers board, recalls the stream conditions. … These
extremely low-water conditions returned in the drought years of
2018, 2020 and 2021, with river flows near the fish hatchery
just south of Carbondale hovering around 8 to 10 cfs — not
enough to support aquatic life and nowhere near the 100 cfs
that the state of Colorado says is the minimum needed to
maintain a healthy stream.
What goes up must come down — perhaps even for things as
massive as Lake Powell. That’s the topic of the Glen Canyon
Institute’s March 15 event, “Glen Canyon Rises.” Featuring
artists, musicians and writers, the event celebrates the
re-emergence of the legendary canyon as the water table keeps
dropping in the massive reservoir shrouding the canyon, Lake
Powell. The Moab Times-Independent spoke with two of the
event’s participants, writer (and former Salt Lake Tribune
reporter) Zak Podmore and photographer Dawn Kish, about their
work to document the return of the southern Utah canyon
sometimes called America’s lost national park.
With climate change compounding the strains on the Colorado
River, seven Western states are starting to consider long-term
plans for reducing water use to prevent the river’s reservoirs
from reaching critically low levels in the years to come. But
negotiations among representatives of the states have so far
failed to resolve disagreements. And now, two groups of states
are proposing competing plans for addressing the river’s
chronic gap between supply and demand. In one camp, the three
states in the river’s lower basin — California, Arizona and
Nevada — say their approach would share the largest-ever water
reductions throughout the Colorado River Basin to ensure
long-term sustainability.
Facing rising costs and rates, the leaders of San Diego’s water
lifelines are looking to sell some of its most expensive
supply: de-salted ocean water from a massive plant in Carlsbad.
But, at the same time, they’re also trying to make more of
it. Dan Denham, the San Diego County Water Authority’s new
general manager, says he wants to expand seawater desalination
not because he thinks San Diego needs more water, but because
he thinks they can sell it and recoup at least a little of the
massive investment local rate payers have made on the plant.
… “We’re looking to expand the plant as an opportunity for
users, whether that’s in southern California or the lower
Colorado River basin,” Denham said.
At a recent listening session hosted by Attorney General Kris
Mayes, Cochise County residents called on state officials to do
more to protect Arizona’s groundwater — and pointed the finger
at one rural lawmaker for blocking progress. Cochise
County residents such as Anne Carl reported that mega farms,
dairies and lithium mines are sucking the groundwater out of
the earth and leaving it dry which causes the ground to shake
and crack. … Residents blamed Rep. Gail Griffin
(R-Hereford), the powerful chair of the House Natural
Resources, Energy and Water Committee, for blocking bills that
they say would protect their water rights. Mayes, a Democrat
who’s spoken strongly against drill permits previously awarded
to foreign-owned companies, suggested they vote her out and
vowed to act if the Legislature will not.
As an endorheic—or terminal—lake with no outlet, Mono Lake
loses water naturally only through evaporation. Evaporation is
a complex process, influenced by radiation, wind, temperature,
and humidity. The rate of evaporation varies across seasons and
over the lake’s surface. With no long-term observational data
of evaporation at Mono Lake, the effect of evaporation on the
water balance is not well understood. Longtime Mono Lake
Committee hydrogeographer Peter Vorster studied evaporation
here for a short period in the early 1980s. He determined Mono
Lake loses nearly four vertical feet of water to evaporation
each year. With a more current understanding of evaporation
specifically at Mono Lake, the Committee can better estimate
lake level fluctuation.
The planet has experienced its ninth consecutive month of
record-breaking warmth, with a simmering February rounding out
the Northern Hemisphere’s hottest meteorological winter on
record, international climate officials announced this week.
The global surface temperature in February was 56.4 degrees —
about 0.2 degrees warmer than the previous February record set
in 2016, according to the European Union’s Copernicus Climate
Change Service. … While much of the Northern hemisphere,
including the United States, experienced its warmest
meteorological winter on record, parts of Southern California
and Los Angeles saw temperatures below their historical
average, according to a report from AccuWeather. The state
ended the month with a major winter blizzard that dumped
up to 10 feet of snow across portions of the Sierra
Nevada.
Rep. David Valadao (R–Hanford) has secured $55 million in
direct funding for community improvement projects.
Fifteen projects throughout Congressional District 22 will
receive federal grants, per Valadao’s request. The big
picture: The largest project on the list is $9 million to
construct a new homeless shelter campus in
Bakersfield. … Delano’s Well 42 project will receive $6
million to fund the creation of a new city well and treatment
plant to provide clean and contaminant free water.
… Here’s a look at the rest of the projects that Valadao
secured funding for: … $1.75 million for the city of Lindsay
to replace an old main pipeline to improve water quality. $3.25
million for the Arvin-Edison groundwater recharge project to
reduce landowner’s groundwater pumping and provide in-lieu
groundwater recharge.
The seven U.S. states that draw water from the Colorado
River basin are suggesting new ways to determine how the
increasingly scarce resource is divvied up when the river can’t
provide what it historically promised. The Upper Basin and
the Lower Basin states, as neighbors, don’t agree on the
approach. Under a proposal released Wednesday by Arizona,
California and Nevada, the water level at Lake Mead — one of
the two largest of the Colorado River reservoirs — no longer
would determine the extent of water cuts like it currently
does. The three Lower Basin states also want what they say is a
more equitable way of distributing cuts that would be a 50-50
split between the basins once a threshold is hit.
With National Groundwater
Awareness Week approaching and 2024 marking

Act in California, upcoming Water Education Foundation
tours and events will help you gain a deeper understanding of
groundwater fundamentals. Join us April 5 for our
annual Water
101 Workshop, which includes a session that
will provide an overview of the state’s groundwater
resources, its importance in the state’s water supply, its
history of use and overuse and the Sustainable Groundwater
Management Act (SGMA). Learn what other topics will be covered
and register
here. Workshop participants can also join
the Groundwater
Tour the day before the workshop. And in
April, our three-day Central Valley
Tour will have a strong focus on groundwater as it
moves through the San Joaquin Valley.
So many hurdles are impacting new home construction, yet one is
quickly growing more urgent and critical—access to water. In
more and more places across the country, access to healthy,
safe, and sustainable water supply is causing restrictions on
new home building permits and challenging current homeowners
with new water use policies. This challenge is triggering
states and municipalities to reconsider new developments,
halting them or shutting them down completely at a time when
housing supply is at critically low levels. Groundwater
shortages have shut down new permits in parts of Arizona where
new homes would rely on wells. A large development with
thousands of homes north of Las Vegas also was shut down due to
concerns over water supply. -By Jennifer Castenson, vice-president of ambassador
and industry partner programs at Buildxact, providing
leadership and collaboration across the various verticals
involved in custom homebuilding and remodeling.
To adapt to climate extremes and become more water resilient in
California, modernizing the state’s water data—including the
way it is collected, stored, shared and used—may lead to more
informed decisions. Improving data practices to best manage
California’s water resources helped drive discussions last week
as state and local water managers, farmers, environmentalists
and others gathered in Sacramento for the 62nd annual
California Irrigation Institute Conference. … With a
theme of “Fluid Futures: Adapting to Extremes,” the Feb. 26-27
event focused on leveraging information and data technology to
help with water-management decisions. Erin Urquhart, water
resources program manager for the National Aeronautics and
Space Administration, offered insights on the benefits of
Earth-observing missions that gather water data from space.
After a wet year and a push to conserve water in the Southwest,
federal officials say the risk of the Colorado River’s
reservoirs declining to critically low levels has substantially
eased for the next couple of years. The Biden administration’s
top water and climate officials said the rise in reservoir
levels and the ongoing conservation efforts will provide some
breathing room for the region’s water managers to come up with
new long-term rules to address the river’s chronic
overallocation problem and the worsening effects of climate
change. … The states proposed the short-term cuts to
deal with water shortages through 2026, when the current rules
for managing the river expire. The Bureau of Reclamation
released its final analysis of the water reductions
on Tuesday …
With many areas of Southern California starved for shade, the
region’s largest water supplier has launched a rebate program
offering residents and businesses up to $500 as an incentive to
plant trees. The Metropolitan Water District of Southern
California on Tuesday announced the addition of the tree
incentive to its long-standing turf-replacement program, which
offers cash to property owners who rip out water-guzzling grass
and replace it with drought-tolerant landscaping. Starting
this week, new applicants can seek a $100 rebate for each
eligible tree planted — up to five trees total — as part of
their turf-replacement project, according to a spokesperson for
the district.
On March 1, 2024, the California Department of Fish and
Wildlife (CDFW) held its CDFW Annual Salmon Information Meeting
via a webinar. The prognosis for a 2024 salmon season does not
look good. The closure of all California salmon fishing in 2023
brought an uptick in salmon escapement to 133,000 in the
Sacramento River, which is somewhat positive. The forecast for
this year’s fishable stock in the ocean (made up of broodyears
2021-2023), however, is not much better than last year’s, with
the lingering effects of the 2020-2022 drought. If a normal
fishery had been held last year or were to be held this year,
the salmon stocks would no doubt fall into an “over-fished”
status.
The Watershed Protection and Forest Recovery Act would create a
new Emergency Forest Watershed Program at the U.S. Department
of Agriculture to aid and streamline watershed recovery efforts
on U.S. Forest Service lands. The bill is intended to help
communities protect their water supply after natural disasters
on U.S. Forest Service lands. The bill was introduced by U.S.
Senators Michael Bennet, D-Colo., Mitt Romney, R-Utah alongside
U.S. Representatives Joe Neguse, D-Colo., Celeste Maloy,
R-Utah, Yadira Caraveo, D-Colo. and John Curtis, R-Utah.
According to a press release sent by Bennet’s office, following
the East Troublesome Fire, water providers faced obstacles that
limited their ability to protect drinking water supplies for
communities downstream of the fire.
California almond farms are struggling to pay the bills with
low prices for their nuts. Trinitas Farm, an almond farm in
Oakdale, filed for bankruptcy in February due to falling almond
prices, rising water rates, and high interest rates making it
impossible to keep up. Almond farmers that CBS13 spoke with
agree but said the biggest driving force of this fallout can be
summed up in one word: inflation. “It has now come to the point
where I see the end of that coming, of that generational
farming,” said Bill Van Ryn, who has an almond farm in San
Joaquin County. He said farmers are simply crippled by costs
and that is causing some California almond farmers to file for
bankruptcy, likely with more to follow.
… The American Southwest has become the site of a collision
between two civilization-defining trends. In this desert heat,
the explosive growth of generative AI is pitched against a
changing climate’s treacherous extremes. … Public data
hint at the potential toll of this approach. Researchers at UC
Riverside estimated last year, for example, that
global AI demand could cause data centers to suck up 1.1
trillion to 1.7 trillion gallons of fresh water by 2027.
A monster blizzard that blasted California’s Sierra Nevada with
gusts of up to 190 mph and dumped more than 10 feet of snow
over the weekend shattered the state’s “snow
drought” and significantly boosted vital snowpack
levels. The statewide snowpack by Monday had swelled to
104% of normal for the date, with a snow water equivalent of
24.4 inches. On Thursday — hours before the chilly winter
storm was set to hit — the snowpack had measured only
80% of normal. It was an impressive turnaround compared with
the beginning of the year when the snowpack was 32% of
normal. Officials were optimistic the blizzard would offer
a significant snow boost. It ended up being a game-changer.

After years of dangerous decline in the nation’s groundwater, a
series of developments in Western states indicate that state
and federal officials may begin tightening protections for the
dwindling resource. In Nevada, Idaho and Montana, a string of
court decisions have strengthened states’ ability to restrict
overpumping of groundwater. California is considering
penalizing local officials for draining their aquifers. And the
White House has asked scientists who focus on groundwater to

2023 due to weather patterns that reduced output from wind
farms and drought that affected hydropower. Data released by
the Energy Information Administration shows a decrease of 0.8
percent compared to the prior year. This is a stunning result,
considering that utility-scale renewables have been a
fast-growing part of the electricity mix and are a crucial
resource for the country’s transition away from fossil fuels.
… Hydropower plants generated 239,855 gigawatt-hours,
down 5.9 percent from 2022. The main reason for the decrease
was a drop in water levels at hydroelectric dams in
areas experiencing drought.
As questions about water resources and access continue to build
in the Southwest, some experts are turning to an unlikely place
for solutions: our atmosphere. Atmospheric water harvesting, a
method of water collection that draws water from humidity in
the air, offers a new pathway for water security. Experts
with a focus in areas such as engineering, hydrology, material
science and thermodynamics gathered at Arizona State University
this month for the Atmospheric Water Harvesting Summit — the
first summit of its kind dedicated entirely to atmospheric
water harvesting.
America’s rivers are changing rapidly due to climate change,
and fish are getting confused as a result, a new study has
found. The study, published in the journal Science by
scientists at the University of Leeds in the U.K., found that
climate change is disrupting the seasonal flows of rivers
around the world, which is posing a serious threat to water
supply and ecosystems. Rivers and their reservoirs provide
water for human use, whether for drinking or agricultural
purposes, meaning that changes to their flows can greatly
affect everyday life. … Climate change is also causing
more extreme weather patterns. An example of this can be seen
in California. The state was in the grips of a severe drought
for years, until last year the prolonged dry period was broken
by a deluge of intense storms. These storms caused severe
flooding and landslides that greatly disrupted local
communities.
Growing your food can be a wonderful and fulfilling activity to
connect with nature, improve your health and well-being, and,
oh yeah, save water. California grows more than 400
agricultural commodities, which translates into over one-third
of the vegetables and almost three-fourths of the country’s
fruits and nuts. Regardless of your view on commercial
agriculture, one thing is true, California has prime weather
for growing a wide range of edible plants in your backyard,
balcony, or indoor window sill. Sometimes, gardening is
easier said than done. And more often than not, when we think
about water efficiency and conservation, we think about
removing turf and installing beautiful native landscapes. This
is certainly a wonderful endeavor and can supply a needed
habitat for beneficial pollinators, improve soil health,
support local ecology, and save water.
When Allison Dodds hit the slopes at June Mountain Ski Resort
this past winter the mountain looked a little different than it
had in past years. Not only was there extra snow from 2023’s
historic precipitation, but there was also extra space between
the trees, making it easier for her to maneuver (and shred) her
way down the mountain. Why the extra space? Over the past
two years, CalTrout and Inyo National Forest have been working
together to restore and remove infested and dead whitebark pine
trees on June Mountain. Dodds works as a Project Manager for
CalTrout’s Sierra Headwaters region, and she leads the June
Mountain Forest Health Project. After a century of fire
suppression, forests across the state have become densely
packed and overloaded with dead wood that is primed to burn
intensely and causes fires to spread quickly.
San Luis Obispo has been recognized for its water conservation
program that reduced the city’s water use greatly over the past
decade. The Alliance for Water Efficiency, a nonprofit
organization based in Chicago, awarded the city a platinum
status award for its compliance with the organization’s Water
Conservation and Efficiency Program Operation and Management
Standard. Cities can implement certain water-saving techniques
outlined in the standard — such as a water shortage or drought
plans, public information tactics, water waste ordinances,
landscape efficiency programs and better water metering
practices — to achieve a higher award from the Alliance for
Water Efficiency.
There is a solar-powered revolution going on in the fields of
India. By 2026, more than 3 million farmers will be raising
irrigation water from beneath their fields using solar-powered
pumps. With effectively free water available in almost
unlimited quantities to grow their crops, their lives could be
transformed. Until the water runs out. The desert state of
Rajasthan is the Indian pioneer and has more solar pumps than
any other. Over the past decade, the government has given
subsidized solar pumps to almost 100,000 farmers. Those pumps
now water more than a million acres and have enabled
agricultural water use to increase by more than a quarter. But
as a result, water tables are falling rapidly. There is little
rain to replace the water being pumped to the surface. In
places, the underground rocks are now dry down to 400 feet
below ground.
Arizona’s Auditor General has released a scathing report,
criticizing the State Land Department for leasing land to a
Saudi-owned company in western Arizona at cheap rates. The
company, Fondomonte, used the land — and the groundwater
beneath it — to grow alfalfa for dairy cattle in the
Middle East. State Auditor General Lindsey Perry says the Land
Department’s practices for valuing the land it leases don’t
align with what’s recommended. In addition, state law requires
the department to conduct a mass appraisal of its properties at
least once every 10 years to determine its agricultural rental
rates. But the last one was done in 2005. This resulted in $3.4
million less in revenues going into the land trust that
provides revenues for K-12 education and other beneficiaries.
Negotiations among the seven states that share the
drought-stricken Colorado River have stalled ahead of a March
target date to propose new operating plans for the waterway, as
officials split over which states should absorb the brunt of
cuts triggered by the region’s ongoing drought. The states —
Colorado, New Mexico, Utah and Wyoming in the Upper Basin and
Arizona, California and Nevada in the Lower Basin — are now
expected to submit separate plans to the Biden administration
early next month, rather than a single cohesive plan, according
to representatives of states from both regions. “If there
is interest in getting to a seven-state consensus compromise,
all seven states have to actually compromise and recognize this
is a massive problem that needs solving, not a party primary or
campaign rally,” J.B. Hamby, chair of the Colorado River Board
of California, told E&E News.
Scientists are sounding the alarm that a crucial component of
the planet’s climate system is in gradual decline and could one
day reach a tipping point that would radically alter global
weather patterns. The Atlantic Meridional Overturning
Circulation, or AMOC, is a system of ocean currents that
circulate water in the Atlantic Ocean like a conveyor belt,
helping to redistribute heat and regulate global and regional
climates. New research, however, warns that the AMOC is
weakening under a warming climate, and could potentially suffer
a dangerous and abrupt collapse with worldwide consequences.
… Considering the AMOC is the workhorse of the Atlantic,
the consequences of such a collapse would result in “hugely
chaotic changes in global weather patterns” that extend far
beyond the Atlantic, said Daniel Swain, a climate scientist
with UCLA who was not involved in the study.
One of Colorado’s leading urban water conservation strategies —
turf replacement — could require up to $2.5 billion to save
20,000 acre-feet of water, according to a recent report
commissioned by the state’s top water policy agency. Colorado
communities are facing a drier future with water shortages and
searching for ways to cut down water use. … This
turf-focused strategy has gained new momentum since 2020 and
2021, when the water crisis in the Colorado River Basin became
shockingly apparent (to more than just water experts)
as two enormous reservoirs, lakes Mead and Powell, fell to
historic lows.
Arizona officials are proud of their 1980 state water policy.
The Arizona Groundwater Management Act (GMA), after many
earlier attempts, was approved only after the federal
government threatened to withhold funding for the Central
Arizona Project (CAP) unless Arizona controlled groundwater
pumping. Without the CAP, California would have claimed “our”
Colorado River water and restricted future economic development
in Arizona. The environment wasn’t at the negotiating table
then, so our rivers were on the menu. The GMA managed
groundwater only in limited areas and sacrificed some rivers.
We have now seriously degraded five of Arizona’s major
perennial rivers: the Colorado, Gila, Salt, Santa Cruz, and San
Pedro. Additionally, future perennial flow in the upper Verde
River is deeply threatened. -Written by Gary Beverly, a member of the
Sustainable Water Network steering committee.
To conserve water as California heads into the drier spring and
summer months, the city of Sacramento announced new
watering regulations set to go into effect March 1. According
to the city’s watering schedule ordinance, residents and
businesses in the city of Sacramento are required
to follow a seasonal schedule when watering landscapes
using sprinklers. Here is the
seasonal watering schedule from the
ordinance: Spring and summer From March 1 to October
31: Customers with even-numbered addresses can water
Wednesday and Sunday. Customers with odd-numbered addresses can
water Tuesday and Saturday. Watering must be done before 10
a.m. and/or after 7 p.m. Watering is not allowed 48 hours
after one-eighths inch of rain.
With its Mediterranean climate, California receives most of its
annual precipitation in just a few months, with the bulk of it
falling from December to February. That means that by the time
March 1 comes around, we usually have a good sense of how much
water we’re going to have for the rest of the year. The state
keeps track based on a “water year” that runs from Oct. 1 to
Sept. 30, so the whole winter rainy season will fall in the
same year’s statistics. As of Sunday, California had received
slightly more rain than usual this winter — 105 percent of the
average, according to state data. In some parts of the state,
though, it’s been much rainier than normal. Los Angeles, which
just endured one of its wettest storm systems on record, had
received 159 percent of its annual average rainfall as of
Sunday. San Diego was at 133 percent, and Paso Robles at 160.
It has been far too dry for far too long in Mexico as a
combination of drying reservoirs and increasing population has
caused concerns of a water crisis. According to data from
the National Oceanic and Atmospheric Administration, most
of Mexico, including areas around and to the north of Mexico
City, are in a long-term drought. … Local media
reports that reservoirs could completely be out of water
by late August if conditions don’t improve. … Elizabeth
Carter, an assistant professor of civil engineering and earth
sciences at Syracuse University … notes … that the U.S
engineering projects in rivers that feed many of Mexico’s
northern freshwater sources run dry before reaching Mexico. She
cites the Hoover Dam, Glen Canyon Dam, and the Central Arizona
Project (Colorado River) as examples.
After a warm weekend of 70-degree temperatures in San
Francisco, Sacramento, San Jose, Los Angeles and San Diego, a
big change is coming this week. A major winter
storm is expected to impact Northern and Central
California from Thursday through Sunday. Whiteout conditions
are likely in the Sierra Nevada, where 4 to 10 feet of snow is
expected above 6,000 feet. The snow line could drop below 2,000
feet in the Sierra and parts of the Bay Area on Saturday.
… A weak weather system is expected to bring light
rainfall to the California coast Monday and Tuesday. Up to a
tenth of an inch of rain is forecast for the Bay Area and up to
a quarter inch in San Luis Obispo, Santa Barbara and Los
Angeles.
As California continues to adapt to the impacts of a changing
climate, the State must work to identify future sources of
safe, reliable water for all. This week, the Department of
Water Resources (DWR) released a report identifying future
planned desalination projects to help meet the brackish water
supply goals identified in California’s Water Supply Strategy:
Adapting to a Hotter, Drier Future. As a key strategy in the
Water Supply Strategy, desalination is the process of removing
salts and minerals from brackish water and seawater to produce
water suitable for drinking water, irrigation and other supply
needs. Brackish water is a mix of freshwater and saltwater and
occurs in a natural environment that has
more salinity than freshwater, but not as much
as seawater. In 2020, over 100,000 acre-feet of brackish
water was desalinated for drinking water, which was two-thirds
of the desalinated water produced and used in California.
For the first time in the United States, a tribe in Arizona is
building a solar farm over an irrigation canal to produce clean
energy and save water at a time of unrelenting drought. The
Gila River Indian Community has broken ground on a project to
put solar panels over nearly 3,000 feet of the Casa Blanca
canal south of Phoenix. It’s one phase of a pilot project
designed to eventually help the tribe reach its goal of using
100% renewable power. The idea is modeled after a similar
project in India, says David DeJong, director of the
Pima-Maricopa Irrigation Project. … The Turlock
Irrigation District in California’s Central Valley is
expected to start a project of its own soon. DeJong
says money from the Inflation Reduction Act funded
the solar farm, and it will eventually produce enough
electricity to power several thousand homes.
More than 70 percent of Nevadans consider water supply and
lowering river levels a serious issue, but only a little more
than half believe climate change is, a Colorado College poll
released Wednesday shows. Water continues to be a hot-button
issue for voters who are looking for leaders who can best
address diminishing water availability as the Colorado River
faces historic challenges. Nevada, the driest state in the
nation, is second only to Arizona among Western states for
concern about water. … Though water appears to be at the
top of most Nevadans’ priority lists, only 56 percent of state
residents feel climate change is an extremely or very serious
problem.
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
Antarctica.
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

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

agencies.

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.

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.

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

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.

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.
We explore “frequently asked questions” often posed by the public
and provide answers below. Simply click on the question for the
answer to appear.
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 printed copy of Western Water examines climate change –
what’s known about it, the remaining uncertainty and what steps
water agencies are talking to prepare for its impact. Much of the
information comes from the October 2007 California Climate Change
and Water Adaptation Summit sponsored by the Water Education
Foundation and DWR and the November 2007 California Water Policy
Conference sponsored by Public Officials for Water and
Environmental Reform.
This printed copy of Western Water examines California’s drought
– its impact on water users in the urban and agricultural sector
and the steps being taken to prepare for another dry year should
it arrive.
This printed issue of Western Water examines the
Colorado River drought, and the ongoing institutional and
operational changes underway to maintain the system and meet the
future challenges in the Colorado River Basin.
This printed issue of Western Water explores the
historic nature of some of the key agreements in recent years,
future challenges, and what leading state representatives
identify as potential “worst-case scenarios.” Much of the content
for this issue of Western Water came from the in-depth
panel discussions at the Colorado River Symposium. The Foundation
will publish the full proceedings of the Symposium in 2012.
This printed issue of Western Water examines the issues
associated with the State Water Board’s proposed revision of the
water quality Bay-Delta Plan, most notably the question of
whether additional flows are needed for the system, and how they
might be provided.
This printed issue of Western Water examines the
Colorado River Basin Water Supply and Demand Study and what its
finding might mean for the future of the lifeblood of the
Southwest.
This printed issue of Western Water features a
roundtable discussion with Anthony Saracino, a water resources
consultant; Martha Davis, executive manager of policy development
with the Inland Empire Utilities Agency and senior policy advisor
to the Delta Stewardship Council; Stuart Leavenworth, editorial
page editor of The Sacramento Bee and Ellen Hanak, co-director of
research and senior fellow at the Public Policy Institute of
California.
This printed issue of Western Water This issue of Western Water
looks at climate change through the lens of some of the latest
scientific research and responses from experts regarding
mitigation and adaptation.
This printed issue of Western Water examines how the various
stakeholders have begun working together to meet the planning
challenges for the Colorado River Basin, including agreements
with Mexico, increased use of conservation and water marketing,
and the goal of accomplishing binational environmental
restoration and water-sharing programs.
This printed issue of Western Water looks at California
groundwater and whether its sustainability can be assured by
local, regional and state management. For more background
information on groundwater please refer to the Foundation’s
Layperson’s Guide to Groundwater.
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
understand the complex issues surrounding the elaborate systems
and testing that go into delivering clean, plentiful water to
households throughout the state.

The 24-page Layperson’s Guide to California Water provides an
excellent overview of the history of water development and use in
California. It includes sections on flood management; the state,
federal and Colorado River delivery systems; Delta issues; water
rights; environmental issues; water quality; and options for
stretching the water supply such as water marketing and
conjunctive use. New in this 10th edition of the guide is a
section on the human need for water.
The 24-page Layperson’s Guide to the Central Valley Project
explores the history and development of the federal Central
Valley Project (CVP), California’s largest surface water delivery
system. In addition to the project’s history, the guide describes
the various CVP facilities, CVP operations, the benefits the CVP
brought to the state and the CVP Improvement Act (CVPIA).
The 24-page Layperson’s Guide to the Delta explores the competing
uses and demands on California’s Sacramento-San Joaquin Delta.
Included in the guide are sections on the history of the Delta,
its role in the state’s water system, and its many complex issues
with sections on water quality, levees, salinity and agricultural
drainage, fish and wildlife, and water distribution.
Redesigned in 2017, this beautiful map depicts the seven
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).

Our 24×36 inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
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.
