Unlike California’s majestic rivers and massive dams and
conveyance systems, groundwater is out of sight and underground,
though no less plentiful. The state’s enormous cache of
underground water is a great natural resource and has contributed
to the state becoming the nation’s top agricultural producer and
leader in high-tech industries.
Groundwater is also increasingly relied upon by growing cities
and thirsty farms, and it plays an important role in the future
sustainability of California’s overall water supply. In an
average year, roughly 40 percent of California’s water supply
comes from groundwater.
A new era of groundwater management began in 2014 with the
Sustainable Groundwater Management Act, which requires local
and regional agencies to develop and implement sustainable
groundwater management plans with the state as the backstop.
California’s changing climate brings new challenges each year
for water managers as they navigate extreme shifts from drought
to flood while working to ensure safe, reliable water supplies
for California’s 39 million residents. Water managers address
these challenges in their local watersheds, which are often at
the forefront of the impacts of climate change.
The land had been sinking so fast for so long that the canal
was failing, so they built an entire new canal, but now that’s
sinking as well. It’s a dramatic reminder that after two good
years, California’s water challenges still run deep. The
Friant-Kern Canal, which runs along the east side of the San
Joaquin Valley, and it is the lifeline for many farmers and
communities in that region. The system starts at Millerton
Lake, and from there, it runs 152 miles to the south, powered
entirely by gravity. But gravity means going downhill and that
has gotten complicated. Decades of groundwater pumping have
caused the valley floor to sink, and the canal with it. KPIX
first toured the site back in August of 2022. The fix is a
duplicate canal built right along side the old one, only
higher, so the water can still flow downhill.
Rosana Monge clutched her husband’s death certificate and an
envelope of his medical records as she approached the
microphone and faced members of the water utility board on a
recent Monday in this city in southeast New Mexico. “I
have proof here of arsenic tests — positive on him, that were
done by the Veterans Administration,” she testified about
her husband, whose 2023 records show he had been diagnosed with
“exposure to arsenic” before his death in February at age 79.
“What I’m asking is for a health assessment of the community.”
… Naturally occurring in the soil in New Mexico, arsenic
seeps into the groundwater used for drinking. In water, arsenic
has no taste, odor or color — but can be removed with
treatment. Over time, it can cause a variety of health
problems, including cancer, diabetes and heart disease,
endangering the lives of people in this low-income and
overwhelmingly Latino community.
Proposed state legislation to modify California’s longstanding
farmland conservation law could pave the way for large swaths
of farm acreage to be repurposed as sites for renewable energy
projects. The California Land Conservation Act of 1965,
commonly known as the Williamson Act, preserves farmland by
assessing property taxes based on the land’s agricultural value
rather than its full market value. Landowners with Williamson
Act contracts, which cover about half the state’s 30 million
acres of farm and ranchland, generally see a 20% to 75%
reduction in property taxes. … The proposed legislation
seeks to align the state’s renewable energy and groundwater
management goals. California’s Sustainable Groundwater
Management Act, or SGMA, requires users to bring groundwater
basins into balance within the next two decades.
Santa Clara County residents could see higher water bills in
the upcoming year, as one water agency looks for ways to cover
costs. Valley Water, the region’s main water supplier, is
proposing raising groundwater production charges on cities and
private water retailers. The increase will be passed on to
household ratepayers through local water companies such as San
Jose Water. This could add $8.78 a month to customers’ bills in
the upcoming fiscal year. Valley Water is spending big to
fix the Anderson and Pacheco dams and other projects that hold
and protect the county’s water supply from climate change. The
board of directors is looking for more money amid a
multimillion-dollar structural deficit, putting residents on
the hook for the district’s losses.
In much of the United States, groundwater extraction is
unregulated and unlimited. There are few rules governing who
can pump water from underground aquifers or how much they can
take. This lack of regulation has allowed farmers nationwide to
empty aquifers of trillions of gallons of water for irrigation
and livestock. Droughts fueled by climate change have
exacerbated this trend by depleting rivers and reservoirs,
increasing reliance on this dwindling groundwater. In many
places, such as California’s Central Valley, the results
have been devastating. As aquifers decline, residential wells
start to yield contaminated water or else dry up
altogether, forcing families to rely on emergency deliveries of
bottled water.
Pretty much every time I write about the amount of Colorado
River water that is consumed to irrigate alfalfa and hay,
readers respond with a comment or question about how much of
the alfalfa — and therefore Colorado River water — is shipped
overseas. … It is true that Western farms export alfalfa
to foreign countries. … But there’s a big caveat here: Many
farms in Arizona — and most if not all of the Saudi Arabia
owned ones — irrigate with groundwater, not with water diverted
from the Colorado River.
The troubled Chiquita Canyon Landfill in Castaic received a new
violation last week from a state water agency for pumping
untreated leachate water from the landfill into local waterways
that empty into the Santa Clara River. A violation letter dated
April 9 was sent to the landfill operators by the Los Angeles
Regional Water Quality Control Board, raising concerns that the
landfill’s wastewater may reach groundwater sources fed by the
river and used for drinking water.
The Metropolitan Water District plans to spend up to $250
million on four non-traditional water projects that, combined,
could supply up to 100,000 Southern California households over
the next few years. Wastewater recycling, rainwater reclamation
and transforming ocean water into drinking water are some of
the technologies that could get money in the coming wave of
funding from MWD. The Los Angeles-based wholesaler, which helps
transfer water from Northern California and the Colorado River
to 26 retail water districts in the Los Angeles region, has
spent about $700 million on smaller, non-traditional water
projects since launching its Local Resources Program in 1990.
The amounts announced Monday, April 15, represent some of MWD’s
biggest investments in water innovation to date.
Kings County growers will face millions of dollars in fees and
a mandate to report groundwater pumping after California
officials voted unanimously today to put local agencies on
probation for failing to protect the region’s underground water
supply. The unprecedented decision is a first step that could
eventually lead to the state wresting control of a groundwater
basin in a severely depleted part of the San Joaquin
Valley. Before issuing the probation order, the State
Water Resources Control Board had repeatedly warned five
groundwater agencies in Kings County that their management plan
for the Tulare Lake basin is seriously deficient, failing to
rein in the dried-up wells, contaminated water and sinking
earth worsened by overpumping.
As part of a $250 million commitment to support four water
supply projects in Southern California, Los Angeles will
receive $139 million over 25 years for its Groundwater
Replenishment Project in the San Fernando Valley, officials
announced on Monday, April 15. Earlier this month, the
Metropolitan Water District of Southern California’s Board of
Directors approved separate agreements with water agencies,
including the city of Los Angeles, as part of its Local
Resources Program. The Metropolitan Water District is a
state-established wholesaler that provides water for 19 million
people in six counties. The Local Resources Program aims to
provide economic incentives for water developed and produced
from groundwater clean-up, water recycling and seawater
desalination throughout the agency’s six-county service area.
For the first time in California history, state officials are
poised to crack down on overpumping of groundwater in the
agricultural heartland. The State Water Resources Control
Board on Tuesday will weigh whether to put Kings County
groundwater agencies on probation for failing to rein in
growers’ overdrafting of the underground water supply.
Probation — which would levy state fees that could total
millions of dollars — is the first step that could allow
California regulators to eventually take over management of the
region’s groundwater.
A stretch of California that’s considered one of the
fastest-sinking areas in the nation, where farms have pumped so
much water from the ground that the land has slowly collapsed,
is on the verge of state intervention. In a first-ever move,
California regulators are looking to step in and monitor
groundwater pumping in the Tulare Lake subbasin, an
837-square-mile hydrological region flush with cotton, hay and
almonds between Fresno and Bakersfield. Because of heavy
pumping, some places here are sinking a foot a year, causing
roads to buckle and canals to crack. … The looming
confrontation between the state and water agencies marks the
latest, and one of the most significant, developments with
California’s decade-old groundwater legislation, the
Sustainable Groundwater Management Act, or SGMA.

… U.S. Geological Service data shows Teton Valley’s aquifer
steadily declined in recent decades as development increased
and crop watering systems became more efficient, reducing
infiltration by replacing flood irrigation with pivots and
sprinklers. In addition, the area’s transition from
agricultural valley to recreation hub has meant less acreage
being watered: farms replaced by subdivisions full of houses
with domestic wells, each one a straw guzzling from the
valley’s all-important aquifer. … Recharge has benefited
farmers and fish in western communities like Idaho’s Eastern
Snake River Plain and California’s Central Valley, and the
group believes the data shows it can work in the Teton Basin.
They hope it can. In addition to providing a bulwark against
future water shortages or legislative changes to water rights
laws, they want to do something groundbreaking: create a
market-based system to pay farmers for incidental recharge.
The Commerce Department announced Monday it pledged up to
$6.6 billion to Taiwanese semiconductor manufacturer TSMC,
which will add a third chip manufacturing facility in Arizona
to the two in the works. The grant will go down in Washington
as one of the crown jewels of the Biden administration’s
initiative to bring the supply chain for ubiquitous—and
strategically vital—computer chips back to the United
States. But in Phoenix, where the factories are going to
be built, TSMC faces a lingering question: where’s the water
going to come from in one of the driest cities in the
country?
As the date of reckoning for excessive groundwater pumping in
Tulare County grows closer, lobbying by water managers and
growers has ramped up. The Friant Water Authority, desperate to
protect its newly rebuilt – yet still sinking –
Friant-Kern Canal, has beseeched the Water Resources Control
Board to get involved. Specifically, it has asked board members
to look into how the Eastern Tule Groundwater Sustainability
Agency (GSA) has, or has not, curbed over pumping that affects
the canal. Meanwhile, the Eastern Tule groundwater agency has
been doing a bit of its own lobbying. It recently hosted all
five members of the Water Board on three separate tours of the
region, including the canal. Because the tours were staggered,
there wasn’t a quorum of board members, which meant they
weren’t automatically open to the public.
Arizona House Republicans convened in a newly created committee
Thursday afternoon to discuss an investigation into the state’s
Democrat attorney general. The conservative lawmakers announced
the creation of the House Committee on Executive Oversight
Wednesday in response to Attorney General Kris Mayes’ ongoing
investigations into “megafarms” she says are overusing
groundwater and draining the wells of rural Arizonans. …
Mayes has recently indicated in multiple town halls across
rural Arizona, specifically La Paz County, her intent to file a
public nuisance complaint against large industrial farms and
corporations that she says are sucking rural Arizonans dry.
As Attorney General Kris Mayes gathers evidence to take action
against corporate farms’ groundwater pumping, some lawmakers
would like to establish protections that discourage such
lawsuits. Agricultural operations could get their legal fees
paid by the plaintiff if they are sued in a nuisance action to
reduce or take away their water use under a bill filed early
this year by state Rep. Austin Smith, R-Wittmann. The measure
would have a “chilling effect” on new approaches to reduce
groundwater use, several legal experts told The Arizona
Republic, because the claimant would need to pay filing fees
and attorney fees for themselves and the sued party.
The Sacramento County district attorney’s office has sued a
state agency alleging that storage tanks are leaking hazardous
substances under several downtown buildings, including the
state Capitol. The lawsuit, filed Tuesday in Sacramento
Superior Court against the California Department of General
Services, alleges the leakages are also happening in Oakland.
It was filed jointly by Sacramento County District Attorney
Thien Ho and Alameda County District Attorney Pamela Price. The
district attorneys filed the lawsuit “to protect public health
and the environment from harm due to releases of hazardous
substances from leaking Underground Storage Tanks, including
harm to groundwater and surface waters and against harm from
indoor air impacts,” the lawsuit stated.
At the Indian Wells Valley Groundwater Authority board meeting
on March 29, the IWVGA board approved motions to reimburse two
domestic well owners who had to replace their wells due to
declining groundwater levels. IWVGA reimbursed $37,996 for the
Halpin Well and $31,082 for the Byerly Well. Reimbursement
covers the estimated current value of the exhausted well and
the incremental costs of drilling a deeper well. California’s
Sustainable Groundwater Management Act requires groundwater
basins like the IWV groundwater basin to reach sustainability
by 2040. This is why the IWVGA initially formed to draft and
implement a Groundwater Sustainability Plan.
The $171 million Kern Fan Groundwater Storage project – with a
unique “eco-twist” – received another chunk of public funding
just as the first section of the 1,300-acre project had a
formal christening on Wednesday. Officials with Rosedale-Rio
Bravo Water Storage District, Irvine Ranch Water District and
the Bureau of Reclamation gathered at the project site near
Enos Lane west of Bakersfield to look over construction of the
first part of Phase 1, which began in February. The Bureau
announced earlier in the week that it had approved a $3.9
million grant for the project, which is in addition to $4.7
million awarded by the Bureau in 2023. That funding requires a
75% match from Rosedale-Rio Bravo and Irvine Ranch.
The San Luis Valley Groundwater Basin stretches from San Luis
Obispo to Edna Valley — but a toxic chemical swirling in the
water prevents the city from using the resource for drinking
water. That will soon change, however. San Luis Obispo won a
$6.6-million grant to install wells that remove
tetrachloroethylene, a chemical also known as PCE, from the
groundwater, according to city water resources program manager
Nick Teague. The wells should be operational by 2026 and will
allow the city to fulfill about 12% of its drinking water
needs, he said.
Groundwater in Arizona belongs to all of us. It is a public
resource and sensible management of it is vital to our shared
future. But instead of fulfilling their obligation to
protect this finite and diminishing water supply, Arizona’s
Republican legislators have introduced dozens of bills at the
statehouse aimed at enriching residential developers and
corporate farmers who want to expand their groundwater
use. Many of these bills are advancing and will end up on
the governor’s desk. One intent of these bills is to
weaken the state’s assured water supply requirement for
development in urban areas. This crucial consumer protection
prevents the sale of subdivision lots that lack a 100-year
water supply, thereby assuring our desert state’s
longevity. -Written by Kathleen Ferris, a Phoenix water
attorney and sits on the Governor’s Water Policy
Council.
The basin depends on 7,650 acre feet of natural inflow each
year but users pump out nearly 28,000 acre feet annually,
creating a severe overdraft. As the Authority has worked to
comply with the Sustainable Groundwater Management Act (SGMA)
to bring the basin into balance numerous legal actions have
erupted. The Authority restricted pumping for most users. The
U.S. Navy, which operates the China Lake Navale Weapons Base in
the basin, got the lion’s share of pumping. While agricultural
users, such as Mojave Pistachios, which started planting in the
high desert around 2010, received zero pumping allocation.
Attorney General Kris Mayes told La Paz County residents she’s
considering a lawsuit to stop corporate farms from overpumping
groundwater there and in Cochise County. Her investigators are
seeking examples of harm such as dry wells, cracked foundations
and dust on which to build a possible case using the state’s
nuisance laws, she said Thursday.
Residents at Friendly Acres Mobile Home Park were given bottled
water and warned about possible contamination in their
well during a March meeting organized by the Central Valley
Regional Water Quality Control Board and California’s Division
of Drinking Water. First reported by the Red Bluff Daily News,
the concern stems from alarming levels of per- and
polyfluoroalkyl substances. Those man-made chemicals, called
PFAS, are used to make a huge number of modern products like
stain-resistant material, nonstick cookware, food packaging and
waterproof clothing. They’ve also been linked to health impacts
including cancer, liver and thyroid damage.
A generational issue for the families living in San Lucas
continues as they’ve gone decades without drinking water. Soon
federal, state, and local leaders will secure nearly a million
dollars to build a pipeline to King City. … Plants not
growing, animals dying, young children unable to bathe, this is
the reality for those living in the unincorporated South
Monterey County town of San Lucas.
Kings County growers are organizing to stop a set of
groundwater and land fees they say will wipe out small farmers,
even as the drumbeat of a looming state takeover grows louder.
Managers of the Mid-Kings River Groundwater Sustainability
Agency (GSA), which covers the northern tip of Kings County,
have been holding a flurry of meetings asking farmers to
approve the fees – a combination of $95-per-acre-foot of water
pumped and $25-per-acre of land – at its April 23
meeting. That is after April 16, when the state Water Resources
Control Board will hold a hearing to decide whether to put all
of Kings County, known as the Tulare Lake groundwater subbasin,
into probation for failing to come up with an adequate plan to
stop over pumping.
Flooding could affect one out of every 50 residents in 24
coastal cities in the United States by the year 2050, a study
led by Virginia Tech researchers suggests. The study, published
this month in Nature, shows how the combination of land
subsidence—in this case, the sinking of shoreline terrain—and
rising sea levels can lead to the flooding of coastal areas
sooner than previously anticipated by research that had focused
primarily on sea level rise scenarios. … The study
combines measurements of land subsidence obtained from
satellites with sea level rise projections and tide charts,
offering a more holistic projection of potential flooding risks
in 32 cities located along the Atlantic, Pacific and Gulf
coasts.
To address the concern of historic groundwater overdraft in the
San Joaquin Valley, the California Water Institute at Fresno
State, with assistance from students and faculty, conducted a
feasibility study to explore the potential for groundwater
recharge within disadvantaged communities. … The analysis
identified four potential locations for the design and
construction of recharge basins near or in the cities of
Kerman, Raisin City, Caruthers and Laton.
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.
When Kelly Dunham heard that water was gushing out from a test
well earlier this month for a proposed lithium mine in the
middle of this rural city of 900 residents, she went to see it
for herself. Water was surging from the drilling rig and
flooding the test site as berms trapped it and directed the
water toward lagoons once used by an abandoned missile launch
complex nearby. Trucks sucked up the water with pumps and
hauled it away to disposal wells as fast as they could.
The drill had hit pockets of carbon dioxide gas and more water
than expected, according to state regulators and Anson
Resources, the company behind the direct lithium extraction
(DLE) project in which brine is pumped from deep aquifers to
the surface, where lithium and other minerals are extracted
from the water before it is sent back underground.
“Water is Life,” was the Lakota rallying cry at Standing Rock
as thousands weathered severe freezing conditions to stop an
oil pipeline threat to their water. In Arizona water is life
too but here we’re way beyond having our water resources
threatened. They’re right now being needlessly and excessively
plundered for corporate profit as the Arizona Corporation
Commission rolls out the red carpet for fossil fuel energy,
depletes our precious water resources and ends up maximizing
utility shareholders’ dividends. Now most of us can wrap
our heads around this — burning fossil fuels to make
electricity causes and worsens climate change, but it’s harder
to wrap your head around just how much water is consumed in the
process. Here’s how much water is used by different energy
sources to produce 1 megawatt hour of electricity. -Written by Rick Rappaport, a member of Tucson Climate
Coalition, Tucson Chapter of Citizens Climate Lobby and
Arizonans for Community Choice Energy
In what has been a years-long fight to fend off efforts to mine
sites and areas the Quechan Indian Tribe say are culturally
significant, the tribe was victorious in preserving those sites
this week with an unexpected win against Canada’s SMP Gold
Corp. … The federally protected land, under the
U.S. Bureau of Land Management, is culturally significant and
important to the Quechan Indian Tribe and its members have been
vehemently fighting the Oro Cruz mining project for years, with
the support of other tribes, and numerous environmental and
social justice groups and concerned residents behind them.
… After the hearing, White elaborated further and told
the Calexico Chronicle that the tribe is trying to dedicate the
Cargo Muchacho Mountains area as the “Kw’tsán National
Monument”
At the Indian Wells Valley Water District board meeting on
March 11, the Water District board moved forward in learning
about the process of consolidating the Dune 3 water mutual
company into their service area. Some negotiation and planning
still needs to happen before any decision is finalized, but for
the moment the board is willing to cautiously move forward in
the process. The IWV Water District serves water to IWV
residents by pumping water out of the IWV groundwater basin.
However, they are not the only ones doing so. Dotted all across
IWV are domestic well owners and even a few other public or
private organizations resembling a water district. If one of
those organizations fails, an obligation still exists to serve
water to the people in that region.
Last winter’s big rain and snow brought immediate benefits to
California’s water supply and data now shows that there are
long-term benefits, too. According to data gathered by
Sacramento’s Regional Water Authority, a surplus of surface
water following the 2022-2023 winter allowed water managers to
use 17% less groundwater compared to 2022. Historically,
groundwater throughout California’s Central Valley had been
severely overdrawn. Over the past 20 years, policy changes and
more nuanced water management have helped groundwater levels
recover.
Thousands of leaking, idle oil wells are scattered across
California, creating toxic graveyards symbolic of a dying
industry. To tackle this “urgent climate and public
health crisis,” Santa Barbara Assemblymember Gregg Hart
introduced Assembly Bill 1866 last week. The bill would mandate
oil operators to develop plans to plug the 40,000 idle wells
(and counting) in the state within a decade, prioritizing those
within 3,200 feet of vulnerable communities. … Ann
Alexander, senior attorney with the Natural Resources Defense
Council, calls the system “very badly broken.” Companies “just
sit indefinitely on their defunct wells” as they leak methane
gas, pollute the air, and contaminate groundwater.
… Last fall, the county announced its plan to
spend $3.7 million to repair an “unpluggable” well at
Toro Canyon Creek. Drilled in the 19th century, this idle well
has leaked thousands of gallons of crude oil since
the 1990s, contaminating waterways and killing wildlife as a
result.
Members of the state Water Resources Control Board voted
unanimously on Tuesday, March 19, to reduce pumping fees for
groundwater users in subbasins that come under state control,
known as “probationary status.” The controversial fee was
lowered from $40 per-acre-foot of pumped water to $20 per acre
foot. The board will hold its first probationary hearing
on the Tulare Lake subbasin, which covers Kings County, on
April 16. … Groundwater sustainability plans (GSPs) for
Tulare Lake and five other San Joaquin Valley subbasins were
rejected twice by the state as inadequate, which is why they
are now coming before the Water Board to determine if they
should be put into probationary status.
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.
The Kern subbasin, composed of 22 water entities across the
valley portion of Kern County, is working on a groundwater
sustainability plan its members hope will be accepted by the
State Water Resources Control Board after the subbasin’s
initial plan was deemed inadequate. Currently the subbasin has
two main objectives. One is partnering with Self-Help
Enterprises to assist with the administration of a program to
fix domestic wells harmed by over pumping. The other is
gathering support among the 22 entities to participate in the
Friant-Kern Canal subsidence study. Proposed partnership: Under
the proposal, Self-Help would assist with subbasin’s well
issues in several ways.
On the eve of its first subbasin probationary hearing, the
state Water Resources Control Board announced it will vote on
whether to reduce a controversial groundwater extraction
fee. The board will vote at its March 19 meeting on
whether to cut the fee from $40 to $20-per-acre-foot for well
owners in a subbasin placed on probation. It will hold
its first probationary hearing on the Tulare Lake subbasin,
which covers Kings County, on April 16. Then the Tule subbasin,
in the southern half of the valley portion of Tulare County,
will come up for hearing Sept. 17. The extraction fee would
only be charged if the Water Board had to step in and
administer a subbasin in cases where it finds local groundwater
agencies aren’t up to the job.
A Los Angeles County Superior Court judge confirmed that the
Cuyama Valley Groundwater Basin is one connected basin—not
separate subbasins—allowing for the groundwater adjudication to
move forward following a year and a half of delays and
litigation. … The Cuyama Valley Groundwater Basin is one of
California’s 21 critically overdrafted basins that was required
under the 2014 California Sustainable Groundwater Management
Act (SGMA) to create a groundwater sustainability agency (GSA)
and corresponding groundwater sustainability plan.
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.
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.
The California State Water Resources Control Board issued a
$6.6 million grant for a city of San Luis Obispo project
intended to clean up contaminated groundwater. Presently, the
city does not use groundwater for its drinking water supply.
SLO’s potable water supply comes from Whale Rock Reservoir,
Santa Margarita Lake and Nacimiento Reservoir. City
officials have sought to diversify the water supply in an
attempt to achieve “greater drought and climate change
resiliency.” Previously, contamination from
tetrachloroethylene, or PCE, served as a barrier to doing so.
PCE is a toxic chemical produced by dry cleaning and industrial
activities, which took place in the city decades ago. The
cleanup project will consist of the city building two new
groundwater supply wells that are expected to be fully
operation in 2026.
The Friant-Kern Canal was called out specifically as one of the
reasons the state should take over pumping in the Tule
groundwater subbasin in Tulare County. The recommendation was
contained in a recently released staff report to the Water
Resources Control Board. While the report stated groundwater
management plans covering the subbasin didn’t adequately
address subsidence and continued depletion of the aquifer and
degradation of water quality in general, it also noted the
significant harm to the Friant-Kern Canal, which brings water
152 miles south from Millerton Lake to Arvin. Excessive
overpumping caused land beneath a 33-mile stretch of the
Friant-Kern Canal to collapse, creating a sag that reduced the
canal’s carrying capacity south of Pixley by 60%.
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.
Last week, Assemblywoman Esmeralda Soria introduced AB 2060 to
help divert local floodwater into regional groundwater
basins. AB 2060 seeks to streamline the permitting process
to the California Department of Fish and Wildlife in support of
Flood-MAR activities when a stream or river has reached
flood-monitor or flood stage as determined by the California
Nevada River Forecast Center or the State Water Resources
Control Board (SWRCB). This expedited approval process would be
temporary during storm events with qualifying flows under the
SWRCB permit.
How will selling groundwater help keep more groundwater in the
San Joaquin Valley’s already critically overtapped aquifers?
Water managers in the Kaweah subbasin in northwestern Tulare
County hope to find out by having farmers tinker with a pilot
groundwater market program. Kaweah farmers will be joining
growers from subbasins up and down the San Joaquin Valley
who’ve been looking at how water markets might help them
maintain their businesses by using pumping allotments and
groundwater credits as assets to trade or sell when water is
tight.
Join us June 18-20 at the Hyatt Regency San Francisco Airport for the 3ʳᵈ International Conference, Toward Sustainable Groundwater in Agriculture: Linking Science & Policy.

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.
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.
This tour explored the Sacramento River and its tributaries through a scenic landscape while learning about the issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of California’s water and feed into two major projects: the State Water Project and the federal Central Valley Project.

A pilot program in the Salinas Valley run remotely out of Los Angeles is offering a test case for how California could provide clean drinking water for isolated rural communities plagued by contaminated groundwater that lack the financial means or expertise to connect to a larger water system.
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.

Martha Guzman recalls those awful
days working on water and other issues as a deputy legislative
secretary for then-Gov. Jerry Brown. California was mired in a
recession and the state’s finances were deep in the red. Parks
were cut, schools were cut, programs were cut to try to balance a
troubled state budget in what she remembers as “that terrible
time.”
She now finds herself in a strikingly different position: As
administrator of the U.S. Environmental Protection Agency’s
Region 9, she has a mandate to address water challenges across
California, Nevada, Arizona and Hawaii and $1 billion to help pay
for it. It is the kind of funding, she said, that is usually
spread out over a decade. Guzman called it the “absolutely
greatest opportunity.”

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.

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.
The San Joaquin Valley has a big
hill to climb in reaching groundwater sustainability. Driven by
the need to keep using water to irrigate the nation’s breadbasket
while complying with California’s Sustainable Groundwater
Management Act, people throughout the valley are looking for
innovative and cost-effective ways to manage and use groundwater
more wisely. Here are three examples.
Groundwater provides about 40
percent of the water in California for urban, rural and
agricultural needs in typical years, and as much as 60 percent in
dry years when surface water supplies are low. But in many areas
of the state, groundwater is being extracted faster than it can
be replenished through natural or artificial means.
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.
Since 1997, more than 430 engineers,

The bill is coming due, literally,
to protect and restore groundwater in California.
Local agencies in the most depleted groundwater basins in
California spent months putting together plans to show how they
will achieve balance in about 20 years.
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.

Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed
them.
A diverse roster of top
policymakers and water experts are on the
agenda for the Foundation’s 36th annual Water
Summit. The conference, Water Year 2020: A Year
of Reckoning, will feature compelling conversations
reflecting on upcoming regulatory deadlines and efforts to
improve water management and policy in the face of natural
disasters.

To survive the next drought and meet
the looming demands of the state’s groundwater sustainability
law, California is going to have to put more water back in the
ground. But as other Western states have found, recharging
overpumped aquifers is no easy task.
Successfully recharging aquifers could bring multiple benefits
for farms and wildlife and help restore the vital interconnection
between groundwater and rivers or streams. As local areas around
California draft their groundwater sustainability plans, though,
landowners in the hardest hit regions of the state know they will
have to reduce pumping to address the chronic overdraft in which
millions of acre-feet more are withdrawn than are naturally
recharged.
California experienced one of the
most deadly and destructive wildfire years on record in 2018,
with several major fires occurring in the wildland-urban
interface (WUI). These areas, where communities are in close
proximity to undeveloped land at high risk of wildfire, have felt
devastating effects of these disasters, including direct impacts
to water infrastructure and supplies.
One panel at our 2019 Water
Summit Oct. 30 in Sacramento will feature speakers
from water agencies who came face-to-face with two major fires:
The Camp Fire that destroyed most of the town of Paradise in
Northern California, and the Woolsey Fire in the Southern
California coastal mountains. They’ll talk about their
experiences and what lessons they learned.
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.
Atmospheric rivers, the narrow bands
of moisture that ferry precipitation across the Pacific Ocean to
the West Coast, are necessary to keep California’s water
reservoirs full.
However, some of them are dangerous because the extreme rainfall
and wind can cause catastrophic flooding and damage, much
like what happened in 2017 with Oroville Dam’s spillway.

With a key deadline for the
Sustainable Groundwater Management Act in January, one of the
featured panels at our Oct.
30thWater
Summit will focus on how regions around California
are crafting groundwater sustainability plans and working on
innovative ways to fill aquifers.
The theme for this year’s Water Summit, “Water Year 2020: A Year

water, including the imminent Jan. 31, 2020 deadline for
groundwater sustainability plans (GSPs) in high- and
medium-priority basins.
Our event calendar is an excellent
resource for keeping up with water events in California and the
West.
Groundwater is top of mind for many water managers as they
prepare to meet next January’s deadline for submitting
sustainability plans required under California’s Sustainable
Groundwater Management Act. We have several upcoming featured
events listed on our calendar that focus on a variety of relevant
groundwater topics:
Registration opens today for the
Water Education Foundation’s 36th annual Water
Summit, set for Oct. 30 in Sacramento. This year’s
theme, Water Year 2020: A Year of Reckoning,
reflects fast-approaching deadlines for the State Groundwater
Management Act as well as the pressing need for new approaches to
water management as California and the West weather intensified
flooding, fire and drought. To register for this can’t-miss
event, visit our Water Summit
event page.
Registration includes a full day of discussions by leading
stakeholders and policymakers on key issues, as well as coffee,
materials, gourmet lunch and an outdoor reception by the
Sacramento River that will offer the opportunity to network with
speakers and other attendees. The summit also features a silent
auction to benefit our Water Leaders program featuring
items up for bid such as kayaking trips, hotel stays and lunches
with key people in the water world.
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.
Our 36th annual
Water Summit,
happening Oct. 30 in Sacramento, will feature the theme “Water
Year 2020: A Year of Reckoning,” reflecting upcoming regulatory

The Summit will feature top policymakers and leading stakeholders
providing the latest information and a variety of viewpoints on
issues affecting water across California and the West.
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.
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.

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 whims of political fate decided
in 2018 that state bond money would not be forthcoming to help
repair the subsidence-damaged parts of Friant-Kern Canal, the
152-mile conduit that conveys water from the San Joaquin River to
farms that fuel a multibillion-dollar agricultural economy along
the east side of the fertile San Joaquin Valley.
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:
This 2-day, 1-night tour offered participants the opportunity to
learn about water issues affecting California’s scenic Central
Coast and efforts to solve some of the challenges of a region
struggling to be sustainable with limited local supplies that
have potential applications statewide.
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.
In 1983, a landmark California Supreme Court ruling extended the public trust doctrine to tributary creeks that feed Mono Lake, which is a navigable water body even though the creeks themselves were not. The ruling marked a dramatic shift in water law and forced Los Angeles to cut back its take of water from those creeks in the Eastern Sierra to preserve the lake.
Now, a state appellate court has for the first time extended that same public trust doctrine to groundwater that feeds a navigable river, in this case the Scott River flowing through a picturesque valley of farms and alfalfa in Siskiyou County in the northern reaches of California.
This tour explored the Sacramento River and its tributaries
through a scenic landscape as participants learned about the
issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of
California’s water and feed into two major projects: the State
Water Project and the federal Central Valley Project. Tour
participants got an on-site update of Oroville Dam spillway
repairs.
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.
More than a decade in the making, an
ambitious plan to deal with the vexing problem of salt and
nitrates in the soils that seep into key groundwater basins of
the Central Valley is moving toward implementation. But its
authors are not who you might expect.
An unusual collaboration of agricultural interests, cities, water
agencies and environmental justice advocates collaborated for
years to find common ground to address a set of problems that
have rendered family wells undrinkable and some soil virtually
unusable for farming.
As California embarks on its unprecedented mission to harness groundwater pumping, the Arizona desert may provide one guide that local managers can look to as they seek to arrest years of overdraft.
Groundwater is stressed by a demand that often outpaces natural and artificial recharge. In California, awareness of groundwater’s importance resulted in the landmark Sustainable Groundwater Management Act in 2014 that aims to have the most severely depleted basins in a state of balance in about 20 years.
Spurred by drought and a major
policy shift, groundwater management has assumed an unprecedented
mantle of importance in California. Local agencies in the
hardest-hit areas of groundwater depletion are drawing plans to
halt overdraft and bring stressed aquifers to the road of
recovery.
Along the way, an army of experts has been enlisted to help
characterize the extent of the problem and how the Sustainable
Groundwater Management Act of 2014 is implemented in a manner
that reflects its original intent.
We explored the lower Colorado River where virtually every drop
of the river is allocated, yet demand is growing from myriad

California voters may experience a sense of déjà vu this year when they are asked twice in the same year to consider water bonds — one in June, the other headed to the November ballot.
Both tackle a variety of water issues, from helping disadvantaged communities get clean drinking water to making flood management improvements. But they avoid more controversial proposals, such as new surface storage, and they propose to do some very different things to appeal to different constituencies.

Participants of this tour snaked along the San Joaquin River to
learn firsthand about one of the nation’s largest and most
expensive river restoration projects.
The San Joaquin River was the focus of one of the most
contentious legal battles in California water history,
ending in a 2006 settlement between the federal government,
Friant Water Users Authority and a coalition of environmental
groups.
Groundwater replenishment happens
through direct recharge and in-lieu recharge. Water used for
direct recharge most often comes from flood flows, water
conservation, recycled water, desalination and water
transfers.
One of the wettest years in California history that ended a
record five-year drought has rejuvenated the call for new storage
to be built above and below ground.
In a state that depends on large surface water reservoirs to help
store water before moving it hundreds of miles to where it is
used, a wet year after a long drought has some people yearning
for a place to sock away some of those flood flows for when they
are needed.
Sinkholes are caused by erosion of
rocks beneath soil’s surface. Groundwater dissolves soft
rocks such as gypsum, salt and limestone, leaving gaps in the
originally solid structure. This is exacerbated when water is
acidic from contact with carbon dioxide or acid rain. Even
humidity can play a major role in destabilizing water
underground.
Irrigation is the artificial supply
of water to grow crops or plants. Obtained from either surface or groundwater, it optimizes
agricultural production when the amount of rain and where it
falls is insufficient. Different irrigation
systems are not necessarily mutually exclusive, but in
practical use are often combined. Much of the agriculture in
California and the West relies on irrigation.
The United States
Geographical Survey (USGS) defines freshwater as containing
less than 1,000 milligrams per liter dissolved solids. However,
500 milligrams per liter is usually the cutoff for municipal and
commercial use. Most of the Earth’s water is saline, 97.5
percent with only 2.5 percent fresh.
Springs are where groundwater becomes surface water, acting as openings
where subsurface water can discharge onto the ground or directly
into other water bodies. They can also be considered the
consequence of an overflowing
aquifer. As a result, springs often serve as headwaters to streams.
Potable water, also known as
drinking water, comes from surface and ground sources and is
treated to levels that that meet state and federal standards for
consumption.
Water from natural sources is treated for microorganisms,
bacteria, toxic chemicals, viruses and fecal matter. Drinking
raw, untreated water can cause gastrointestinal problems such as
diarrhea, vomiting or fever.
Extensometers are among the most valuable devices hydrogeologists
use to measure subsidence, but most people – even water
professionals – have never seen one. They are sensitive and
carefully calibrated, so they are kept under lock and key and are
often in remote locations on private property.
During our California
Groundwater Tour Oct. 5-6, you will see two types of
extensometers used by the California Department of Water
Resources to monitor changes in elevation caused by groundwater
overdraft.
Flowing into the heart of the Mojave Desert, the Mojave River
exists mostly underground. Surface channels are usually dry
absent occasional groundwater surfacing and flooding
from extreme weather events like El Niño.
Alluvium generally refers to the clay, silt, sand and gravel that
are deposited by a stream, creek or other water body.
Alluvium is found around deltas and rivers, frequently
making soils very fertile. Alternatively, “colluvium” refers to
the accumulation at the base of hills, brought there from runoff
(as opposed to a water body). The Oxnard Plain in Ventura
County is a visible alluvial plain, where floodplains have
drifted over time due to gradual deposits of alluvium, a feature
also present in Red Rock Canyon State Park in Kern County.
A new era of groundwater management
began in 2014 with the passage of the Sustainable Groundwater
Management Act (SGMA), which aims for local and regional agencies
to develop and implement sustainable groundwater management
plans with the state as the backstop.
SGMA defines “sustainable groundwater management” as the
“management and use of groundwater in a manner that can be
maintained during the planning and implementation horizon without
causing undesirable results.”
This issue looks at remote sensing applications and how satellite
information enables analysts to get a better understanding of
snowpack, how much water a plant actually uses, groundwater
levels, levee stability and more.
This handbook provides crucial
background information on the Sustainable Groundwater Management
Act, signed into law in 2014 by Gov. Jerry Brown. The handbook
also includes a section on options for new governance.

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.
Statewide, groundwater provides about 30 percent of California’s
water supply, with some regions more dependent on it than others.
In drier years, groundwater provides a higher percentage of the
water supply. Groundwater is less known than surface water but no
less important. Its potential for helping to meet the state’s
growing water demand has spurred greater attention toward gaining
a better understanding of its overall value. This issue of
Western Water examines groundwater storage and its increasing
importance in California’s future water policy.
This issue of Western Water examines the issue of California
groundwater management, in light of recent attention focused on
the subject through legislative actions and the release of the
draft Bulletin 118. In addition to providing an overview of
groundwater and management options, it offers a glimpse of what
the future may hold and some background information on
groundwater hydrology and law.
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.
20-minute DVD that explains the problem with polluted stormwater,
and steps that can be taken to help prevent such pollution and
turn what is often viewed as a “nuisance” into a water resource
through various activities.
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.
Water truly has shaped California into the great state it is
today. And if it is water that made California great, it’s the
fight over – and with – water that also makes it so critically
important. In efforts to remap California’s circulatory system,
there have been some critical events that had a profound impact
on California’s water history. These turning points not only
forced a re-evaluation of water, but continue to impact the lives
of every Californian. This 2005 PBS documentary offers a
historical and current look at the major water issues that shaped
the state we know today. Includes a 12-page viewer’s guide with
background information, historic timeline and a teacher’s lesson.
This 7-minute DVD is designed to teach children in grades 5-12
about where storm water goes – and why it is so important to
clean up trash, use pesticides and fertilizers wisely, and
prevent other chemicals from going down the storm drain. The
video’s teenage actors explain the water cycle and the difference
between sewer drains and storm drains, how storm drain water is
not treated prior to running into a river or other waterway. The
teens also offer a list of BMPs – best management practices that
homeowners can do to prevent storm water pollution.
Fashioned after the popular California Water Map, this 24×36 inch
poster was extensively re-designed in 2017 to better illustrate
the value and use of groundwater in California, the main types of
aquifers, and the connection between groundwater and surface
water.
Water as a renewable resource is depicted in this 18×24 inch
poster. Water is renewed again and again by the natural
hydrologic cycle where water evaporates, transpires from plants,
rises to form clouds, and returns to the earth as precipitation.
Excellent for elementary school classroom use.
As the state’s population continues to grow and traditional water
supplies grow tighter, there is increased interest in reusing
treated wastewater for a variety of activities, including
irrigation of crops, parks and golf courses, groundwater recharge
and industrial uses.

Seawater intrusion can harm groundwater quality in a variety of
places, both coastal and inland, throughout California.
Along the coast, seawater intrusion into aquifers is connected to overdrafting of
groundwater. Additionally, in the interior, groundwater
pumping can draw up salty water from ancient seawater isolated in
subsurface sediments.
Overdraft occurs when, over a period of years, more water is
pumped from a groundwater basin than is replaced from all sources
– such as rainfall, irrigation water, streams fed by mountain
runoff and intentional recharge. [See also Hydrologic Cycle.]
While many of its individual aquifers are not overdrafted,
California as a whole uses more groundwater than is replaced.
The treatment of groundwater— the primary source of drinking
water and irrigation water in many parts of the United States —
varies from community to community, and even from well to well
within a city depending on what contaminants the water contains.
In California, one-half of the state’s population drinks water
drawn from underground sources [the remainder is provided by
surface water].
Groundwater management is recognized
as critical to supporting the long-term viability of California’s
aquifers and protecting the
nearby surface waters that are connected to groundwater.
California has considered, but not implemented, a comprehensive
groundwater strategy many
times over the last century.
One hundred years ago, the California Conservation Commission
considered adding groundwater regulation into the Water
Commission Act of 1913. After hearings were held, it was
decided to leave groundwater rights out of the Water Code.
California, like most arid Western states, has a complex system
of surface water rights
that accounts for nearly all of the water in rivers and streams.
Groundwater banking is a process of diverting floodwaters or
other surface water into
an aquifer where it can be
stored until it is needed later. In a twist of fate, the space
made available by emptying some aquifers opened the door for the
banking activities used so extensively today.
When multiple parties withdraw water from the same aquifer,
groundwater pumpers can ask the court to adjudicate, or hear
arguments for and against, to better define the rights that
various entities have to use groundwater resources. This is known
as groundwater adjudication. [See also California
water rights and Groundwater Law.]
If California were flat, the volume of its groundwater would be
enough to flood the entire state 8 feet deep. The enormous cache
of underground water helped the state become the nation’s top
agricultural producer. Groundwater also provides a critical hedge
against drought to sustain California’s overall water supply.
In years of average precipitation, about 40 percent of the
state’s water supply comes from underground. During a drought,
the amount can approach 60 percent.
For something so largely hidden from view, groundwater is an
important and controversial part of California’s water supply
picture. How it should be managed and whether it becomes part of
overarching state regulation is a topic of strong debate.
In early June, environmentalists and Delta water agencies sued
the California Department of Water Resources (DWR) and the Kern
County Water Agency (KCWA) over the validity of the transfer of
the Kern Water Bank, a huge underground reservoir that supplies
water to farms and cities locally and outside the area. The suit,
which culminates a decade-long controversy involving multiple
issues of state and local jurisdictional authority, has put the
spotlight on groundwater banking – an important but controversial
water management practice in many areas of California.
Groundwater, out of sight and out of mind to most people, is
taking on an increased role in California’s water future.
Often overlooked and misunderstood, groundwater’s profile is
being elevated as various scenarios combine to cloud the water
supply outlook. A dry 2006-2007 water year (downtown Los Angeles
received a record low amount of rain), crisis conditions in the
Sacramento-San Joaquin Delta and the mounting evidence of climate
change have invigorated efforts to further utilize aquifers as a
reliable source of water supply.
When you drink the water, remember the spring. – Chinese proverb
Water is everywhere. Viewed from outer space, the Earth radiates
a blue glow from the oceans that dominate its surface. Atop the
sea and land, huge clouds of water vapor swirl around the globe,
propelling the weather system that sustains life. Along the way,
water, which an ancient sage called “the noblest of elements,”
transforms from vapor to liquid and to solid form as it falls
from the atmosphere to the surface, trickles below ground and
ultimately returns skyward.
Traditionally treated as two separate resources, surface water
and groundwater are increasingly linked in California as water
leaders search for a way to close the gap between water demand
and water supply. Although some water districts have coordinated
use of surface water and groundwater for years, conjunctive use
has become the catchphrase when it comes to developing additional
water supply for the 21st century.
