The Central Valley is a vital agricultural region that dominates
the center of California, stretching 40-60 miles east to west and
about 450 miles from north to south. It covers 22,500
square miles, about 13.7% of California’s total land area.
Key watersheds are located here: The Sacramento Valley in the
north, San Joaquin Valley and Tulare Basin to the south. In
addition, the Sacramento and San Joaquin rivers drain their
respective valleys and meet to form the Sacramento-San Joaquin
Bay Delta, which flows to the Pacific Ocean via the San Francisco

Californian almonds will benefit from a new public campaign
next week to capitalise on the explosion in plant-based
eating… However, the environmental reputation of the almond
sector is much less favourable. It was once labelled a
“horticultural vampire” by US magazine New Republic for its
perceived role in California’s most recent droughts.
While considerable progress has been made to improve flood
management in the Central Valley, the vast region still faces
significant flood risk. … It has been estimated that
California needs to spend at least $34 billion to upgrade dams,
levees, and other flood management infrastructure.
Accomplishing these upgrades within 25 years would mean
spending $1.4 billion per year—roughly twice the current level
These changes will be substantial, multi-faceted, and often
rapid. Some changes will be irreversible. Many changes are
inevitable. Some will say today’s Delta is doomed. It will be
important for California to develop a scientific program that
can help guide difficult policy and management discussions and
decision-making through these challenges.
And as in other parts of the United States, black migrants were
met with Jim Crow-style racism: “Whites Only” signs, curfews
and discriminatory practices by banks. Often, the only places
black families could settle were on arid acres on the outskirts
of cultivated farmland — places like Teviston… Today, the
legacy of segregation in the Central Valley reverberates
underground, through old pipes, dry wells and soil tainted by
shoddy septic systems.

The initiative to establish an ecosystem marketplace began in
2017 with the Noble Research Institute, which started working
on developing protocols to verify carbon sequestration and

A decade in the making, regulators on Wednesday approved new
rules that will require the agricultural industry and others to
shield nitrates and salt from seeping into groundwater

officer of the Central Valley Water Quality Control Board.
When nitrogen-based fertiliser runs into water systems it can
result in toxic algae blooms, leading to oxygen depletion and
vast oceanic ‘dead zones’. Evidence suggests their use also
contributes to air pollution, increased rates of cancer and
reduced biodiversity, as well as emitting nitrous oxide – an
extremely potent greenhouse gas. … A team of scientists, led
by the University of California, Davis, has come up with a
five-step plan to tackle this two-sided problem.
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
California’s Central Valley is one of the most productive

How can the short memory of the public maintain the long-term
commitments of water projects and conservation behaviors? On
one hand, California’s recent extended drought demonstrated
that the public water users could reduce their water use, but
can it be maintained permanently?
As we are enter another hurricane season, the National Flood
Insurance Program (NFIP) is on its 12th short-term extension

people are asking, how did we get here?
The “Water Justice Act” would invest nearly $220 billion in
clean and safe drinking water programs, with priority given to

California Influencers this week answered one or both of the
following the questions: What are your thoughts regarding Gov.
Gavin Newsom and the Legislature’s decision to use money from
the state’s cap-and-trade funding to improve drinking water for
at-risk Californians? How can California best provide safe and

these new strawberries are the best of both worlds: the
strawberries will use less water, fertilizer and pesticides and
still produce more, healthier, higher-quality strawberries.
Moving forward, we have an opportunity and an obligation to
build on this agreement by addressing the barriers that
confront small water systems that often have the most
difficulty delivering safe, clean water. As advocates and

communities with greatest needs, the public health community
has the responsibility to step forward and align itself with
the struggle for water as a human right.
River towns can start by restricting floodplain development so
that people and property will not be in harm’s way. This will
create space for rivers to spill over in flood season, reducing

The Sustainable Groundwater Management Act (SGMA) is an
historic opportunity to achieve long-term sustainable
groundwater management and protect drinking water supplies for
hundreds of small and rural low-income communities, especially
in the San Joaquin Valley.
The California Senate on Monday sent legislation to Gov. Gavin
Newsom that will spend $130 million a year over the next decade
to improve drinking water for about a million people. …
Newsom had proposed a tax on most residential water bills to
address the problem. Instead, the Senate approved a bill that
would authorize spending up to $130 million each year on the
state’s distressed water districts, with most of it coming from
a fund aimed at fighting climate change.
Legislative leaders reached a compromise with Newsom to take
some money out of a fund used to improve air quality and use it
for drinking water. … The state Assembly approved the
proposal on Friday by a vote of 67-0. It now heads to the state
Pistachio trees require somewhere between one-third and
one-half as much water as almond trees. Unlike almond trees,
pistachio trees don’t die during extended droughts. Their
metabolism merely slows and when water returns, they start
producing nuts again. … Pistachios can also handle, as
Duarte’s team discovered, levels of salt that have already
killed many an almond tree.
California’s political leaders have made the long-overdue
decision to clean up the Central Valley’s contaminated drinking
water, and help cash-strapped rural water districts. The catch:
rather than assess a fee on water users or tapping into the
state’s budget surplus, Gov. Gavin Newsom and the Legislature
relied on cap-and-trade money to pay for a portion of the
SGMA inevitably means less water for irrigating farms. … On
one path, the valley could become a patchwork of dusty barren
fields, serving a huge blow to the agriculture sector and rural

On another path, the valley could transform into a pioneering
agricultural region that not only puts food on our nation’s
plates but also supports thriving wildlife habitat, outdoor
recreation, soil health, groundwater recharge and flood
Over 10 years, it would funnel $1.4 billion to the fund for
clean water solutions. The budget has been approved by the
California Legislature, but still needs Gov. Gavin Newsom’s

On the ground, it’s hard to get a fix on the Central Valley; it
flashes by as dun-colored monotony — a sun-stunned void beyond
the freeway berms. … But in “The Dreamt Land,” former L.A.
Times reporter Mark Arax makes a riveting case that this
expanse … as much as the world cities on its coast, holds the
key to understanding California.
Of all the issues that have crossed Gov. Gavin Newsom’s desk
during his first 100 days in office, water might very well be
the most complex. … I am an almond grower from Merced County,

In retrospect, it’s clear: We’ve misunderstood how rivers work.
They don’t follow wishful parameters of the Army Corps of
Engineers’ 100-year flood guidelines, or the routes we’ve
penciled in between levees, or even the climatic expectations
of the past. A national program that presumes we can
choreograph today the floods of tomorrow is fundamentally
flawed. It’s time to recognize that the rivers will have their
way. Therefore we need to get out of the way.
The session, “Navigating the Waters,” drew a crowd of about 150

As the focus on infrastructure retakes center stage in
Washington, we hope lawmakers don’t overlook a prime
opportunity to invest in Western water and irrigation systems.
Here in the West, our dams, irrigation systems, canals and
other infrastructure — much of it more than a century old — are
past due for modernization.
Water is a currency in California, and the low-income
farmworkers who pick the Central Valley’s crops know it better
than anyone. They labor in the region’s endless orchards, made
possible by sophisticated irrigation systems, but at home their
faucets spew toxic water tainted by arsenic and fertilizer
Researchers at the University of California, Davis, looked at

As California’s Central Valley grew into the nation’s leading
agricultural corridor, the region gradually lost almost all of
the wetlands that birds depend on during their migrations along
the West Coast. But a dramatic turnaround is underway in the
valley. Dozens of farmers leave water on their fields for a few
extra weeks each season to create rest stops for birds. The
campaign has not only helped salvage a vital stretch of the
north-south migration path called the Pacific Flyway but also
tested a fresh model for protecting wildlife.

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.

Assessing populations of fall-run Chinook salmon in
California’s Central Valley isn’t as simple as counting how
many adults have returned to a given stream to spawn. A process
known as “source-sink dynamics” may be concealing the fact that
certain populations are not self-sustaining.
The last thing California needs is another tax. But that’s what
Gov. Gavin Newsom has proposed – a regressive water tax that
will hit financially challenged Californians hardest. … Yet
California’s taxpayers have been working so hard they have
showered the state with a $22 billion surplus. Spending a
fraction of that would take care of the clean water problem.
In SB1, State Senate President Pro Tem Toni Atkins provides a
compelling case to protect California’s air, navigable water,

right prescription for California, we believe this legislation
is overbroad, duplicative and unworkable.
The National Flood Insurance Program provides coverage to more
than 5 million households and small businesses across the
United States, including more than 229,000 in California. The
program has been hard hit by payouts from major flood disasters
in recent years and is heavily in debt. The Federal Emergency

A team of Stanford University researchers believe they have
identified the best way to replenish the shrinking aquifers
beneath California’s Central Valley. … The study from
Stanford’s School of Earth, Energy and Environmental Sciences,

unless action is taken, the ground in that region will sink
more than 13 feet over the next 20 years.
Bruce Babbitt, the former Arizona
governor and secretary of the Interior, has been a thoughtful,
provocative and sometimes forceful voice in some of the most
high-profile water conflicts over the last 40 years, including
groundwater management in Arizona and the reduction of
California’s take of the Colorado River. In 2016, former
California Gov. Jerry Brown named Babbitt as a special adviser to
work on matters relating to the Sacramento-San Joaquin Delta and
the Delta tunnels plan.
When Babbitt speaks, people take notice, and he didn’t
disappoint before a packed house at the annual Anne J.
Schneider Lecture April 3 in Sacramento, offering thoughts on
some of California’s thorniest water issues and proposing a
Bay-Delta Compact, a kind of grand bargain to end persistent
conflict surrounding the Sacramento-San Joaquin Delta.
“Flood-MAR” is a resource management strategy that uses flood
water for managed aquifer recharge (MAR) on agricultural lands,
working landscapes, and managed natural landscapes. At the
March meeting of the California Water Commission, a panel
discussed Flood MAR with a focus on using agricultural lands
for groundwater recharge.
In California, the amount of water exiting aquifers under the
state’s most productive farming region far surpasses the amount
of water trickling back in. That rampant overdraft has caused
land across much of the region to sink like a squeezed out
sponge, permanently depleting groundwater storage capacity and
damaging infrastructure. … New research from Stanford
University suggests a way to map precisely where and how to use
groundwater recharge to refill the aquifers and stop the
For the millions of Californians who live and work far from the
Delta, it can be easy to overlook the splendor of the largest
estuary in western North America. Whether you are one mile or
hundreds of miles from the Delta, however, all Californians
have a stake in the survival and preservation of this fragile,
dynamic ecosystem that is also the keystone of the state’s
water supply system.
Venture 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.
Chris Orrock of the California Department of Water Resources
joins the podcast to chat with John Howard and Tim Foster about
what this wealth of snow means for California’s water reserves
and flood dangers, and the implications for wildfires later in
Mention of climate change may still provoke skepticism in other
sectors, but in California’s agriculture industry, the
discussion is less about whether disruption is coming than it
is about how farmers will adapt. A consensus appears to have
emerged that extreme weather conditions — drought and flooding,
hotter summers and milder winters — will increase competition
for irrigation water such that some crops now produced in the
Central Valley may no longer be economically feasible in the
Fortunately, California has developed a forward-looking Central
Valley Flood Protection Plan to meet this challenge. In his
first state of the state address, Gov. Gavin Newsom highlighted
the central tenet of the flood plan—investing in floodplain
improvements that give rivers more room to safely bypass flood
waters around cities and infrastructure.
For the past year the state’s worked to eradicate the rodents
for a second time. The rodents were brought to California in
the 1900s for the fur trade and fur farming. “[The] challenge
is we keep looking and we keep finding more nutria,” said Peter
Tira with the California Department of Fish and Wildlife.
“However, we do know there’s about 1.8 million acres of
suitable nutria habitat. This is the largest nutria eradication
ever attempted in the United States.”
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.
Researchers across the United States say the milder winters of
a changing climate are inducing earlier flowering of temperate
tree fruits, exposing the blooms and nascent fruit to
increasingly erratic frosts, hail and other adverse weather.
The problem is not obvious to consumers, in part because a
harvest collapse in one region can be masked by a bumper crop
in another. But unless breeders can produce more
climate-resilient varieties, fruit-growing regions of the
United States will be seriously disrupted by future warming
scenarios, scientists say.
Duane Waliser of NASA’s Jet Propulsion Laboratory … says as
the climate warms, atmospheric rivers are projected to grow
wider and longer. Powerful ones are also expected to become
more frequent. That could increase water supply in some places.
“But on the other hand, atmospheric rivers come with flood
potential as well, so they’re sort of a double-edged sword, so
More than 400 nutria have been captured in the first year of an
effort to eradicate the invasive South American rodent from
California. The state Department of Fish and Wildlife said
Monday the semi-aquatic rodents were trapped in five counties

Another round of soaking winter weather is on the horizon for
the West Coast, with a series of storms expected to impact the
region through midweek. … “Unsettled weather will continue
across the West Coast this week as more rain and mountain snow

to AccuWeather Meteorologist Max Vido.
France and California face a common challenge of managing
overdraft in intensively exploited aquifers. As of 2018, large
areas of France and California have overexploited groundwater
(see maps below). And both regions have passed landmark
groundwater legislation, the Loi sur l’Eau et les Milieux
Aquatiques (LEMA) of 2006 in France and the Groundwater
Sustainable Management Act (SGMA) of 2014 in California.
In the month since Governor Newsom announced that he does not

project in light of the Governor’s comments…
Every year, millions of waterbirds migrating from Alaska to
Patagonia take a break from that epic journey to rest, eat and
breed in a stretch of wetlands spanning six Western states
called the Great Basin. A warming climate has made that
migration more challenging by altering how mountain snowmelt
flows into the network of lakes and rivers stretching from the
Sierra Nevada to the Rockies, according to a new study.
Our rules, cobbled over time from various state water right
decisions or federal biological opinions, are too rigid. …
Things are done by an aging book. We are not adapting our
management based on testing new hypotheses collaboratively
advanced by stakeholders who are willing to celebrate the
results regardless of outcome.
Climate change is having a profound effect on the millions of
migrating birds that rely on annual stops along the Pacific
Flyway as they head from Alaska to Patagonia each year. They
are finding less food, saltier water and fewer places to breed
and rest on their long journeys, according to a new paper in
Nature’s Scientific Reports.
Recent rains have left the San Joaquin Valley’s reservoirs in
better shape, but groundwater depletion and the resulting
ground subsidence continue to beset farmers and water managers.
What will this year hold? … Your best opportunity to
understand the challenges and opportunities of this vital
resource in the nation’s breadbasket is to join us on our
Central Valley Tour April 3-5.
A bill from Sen. Bill Dodd that would increase legislative
oversight of the controversial Sacramento-San Joaquin Delta
WaterFix project and allow for more public scrutiny has cleared
its first committee hurdle. The action comes less than a month
after Gov. Gavin Newsom said he wants to scale back the project
proposed by former Gov. Jerry Brown to a single tunnel.
After more than a decade in the making, the Sacramento-San
Joaquin Delta National Heritage Area Act by Rep. John

is the first National Heritage Area in California’s
The Sacramento Valley’s flood management system is a good
example where a portfolio of actions has greatly reduced flood
damages and deaths, with relatively little management expense
and attention in a highly flood-prone region. This case also
illustrates how the many individual flood management options
presented in the table can be assembled into a diversified
cost-effective strategy involving the many local, state, and
federal parties concerned with floods.
For a region so crucial to the growth of California as we know
it today, you might think there would be libraries full of
books about the Sacramento-San Joaquin Delta. And yet, as UC
Merced scholar Gregg Camfield wrote several years ago, the most
obvious thing about the literature of the Delta “is how little
there is.” Advocates of the largest estuary on the west coast
of the Americas are trying to collect those scattered bits and
pieces in a new anthology of the Delta.
Heavy rains this winter will help replenish groundwater
aquifers and benefit projects that use excess surface water to
recharge groundwater basins. At the California Department of
Water Resources, planners focus on a voluntary strategy known
as Flood-MAR, which stands for “managed aquifer recharge.” The
strategy combines floodwater operations and groundwater
management in an effort to benefit working landscapes, and
could also aid local groundwater agencies as they implement the
state Sustainable Groundwater Management Act.
The San Joaquin Valley, known as the
nation’s breadbasket, grows a cornucopia of fruits, nuts and
other agricultural products.
During our three-day Central Valley Tour April

The current dilemmas boil down to this: As the state punishes
cannabis growers in the Emerald Triangle for environmental
degradation, it is simultaneously pursuing an aqueduct project
in the Central Valley that environmental groups claim will
cause ecological harm of massive proportions. This project

One tunnel or two, neither idea adds a drop of the water to
needs of the nearly 40 million people who call California home.
The tunnels simply divert existing water supplies while putting
in severe jeopardy the largest freshwater estuary west of the
Mississippi River, the Sacramento-San Joaquin River Delta that
juts into the western edge of Stockton. Clearly, there must be
better solutions. Three approaches leap to mind: storage,
conservation and desalination.
The southern Sierra Nevada is expected to see a pair of storm
systems in the coming days that could create “significant
flooding” over several burn scars in the area, according to
weather officials. … Next week’s storm, which is expected to
hit the area midweek, is the primary source of concern. “That
storm could bring between 2 and 5 inches of rain,” said Kevin
Durfee, meteorologist with the National Weather Service. “If
those rain amounts do materialize, we could be looking at some
significant flooding over the burn scars, and rising water
levels in rivers and streams.”
More rain this winter and an improved water outlook promise
California farmers more flexibility in what annual crops to
grow, even if sluggish commodity prices limit their crop
choices. For example, California cotton acreage is expected to
increase this year to 287,000, according to a
planting-intentions survey by the National Cotton Council.
Citing expected water availability, the council reported
California farmers intend to plant 230,000 acres of pima cotton
and 57,000 acres of upland cotton. That’s up 9.7 percent and
14.4 percent, respectively, from last year.
Now stripped of its once vast wetlands and nearly sucked dry
from the overpumping of groundwater during the West’s
increasingly common droughts, the fertile valley is in need of
a reboot: Its aquifers have shrunk and the remaining water is
often contaminated with nitrate and salts. Citing a new water
law that will have major effects on water suppliers and
farmers, experts are calling for an “all hands on deck”
approach to fixing the valley’s water woes.
The cheering is for a governor who has brought attention to a
problem that’s almost unfathomable in wealthy urban regions. No
Californian in 2019 should have to endure third-world
drinking-water conditions. But there’s ample reason to give the
governor the raspberries, too. That’s because Newsom’s solution
comes right out of former Chicago Mayor Rahm Emanuel’s “you
never want a serious crisis go to waste” playbook.
When it floods in California, the culprit is usually what’s
known as an atmospheric river—a narrow ribbon of ultra-moist
air moving in from over the Pacific Ocean. Atmospheric rivers
are also essential sources of moisture for western reservoirs
and mountain snowpack, but in 1861, a series of particularly
intense and prolonged ones led to the worst disaster in state
history: a flood that swamped the state. What would happen if
the same weather pattern hit the state again?
At our current rate of climate change, many cities in western

Newsom has embraced an idea that has previously failed to gain
traction in Sacramento: new taxes totaling as much as $140
million a year for a clean drinking water initiative. Much of
it would be spent on short- and long-term solutions for
low-income communities without the means to finance operations
and maintenance for their water systems. … But the money
to change that — what’s being called a “water tax” in state
Capitol circles — is where the politics get complicated.
Many no longer recall the Great Midwest Flood despite its
record-breaking precipitation, flooding and $13 billion price
tag. Sure, 1993 seems like a long time ago, but I believe the
reason the flood has left most people’s memory is because, over
the last 25 years, the nation has experienced one devastating,
record-breaking flood after another. Our memories are diluted
by the frequency of such events.
Two experts from Stanford’s Water in the West program explain
the potential impacts on the future of water in California of
the proposed plan to downsize the $17 billion Delta twin
tunnels project. … Leon Szeptycki, executive director
of Stanford’s Water in the West program, and Timothy
Quinn, the Landreth Visiting Fellow at Water in the West,
discussed the future of water in California and potential
impacts of a tunnel system.
At long last, the Sacramento-San Joaquin River Delta
twin-tunnels boondoggle is dead. Good riddance. Gov.
Gavin Newsom made that official Tuesday during his State of the
State address, calling instead for a smaller, single-tunnel
approach that would include a broad range of projects designed
to increase the state’s water supply. Bravo. It’s a
refreshing shift from Gov. Jerry Brown’s stubborn insistence
that California spend $19 billion on a project that wouldn’t
add a drop of new water to the state supply.

Farmers, water managers and government agencies agree:
Groundwater sustainability is critical for California. But
achieving it could bring significant changes to the state’s
agricultural landscape, according to speakers at a Sacramento
gathering of water professionals.
The wet weather broke a daily rainfall record in Sacramento,
with 1.6 inches of rain recorded at the Sacramento Executive
Airport over 24 hours. But the state’s network of flood-control
dams and levees appeared to handle the deluge without major
problems. The National Weather Service issued a flood
warning Wednesday morning for the Sacramento Valley, and it was
expected to remain in place until 6 p.m. Thursday as heavy and
moderate rainfall was forecast to continue through Thursday.
Felicia Marcus, whose push for larger river flows angered
farmers and community leaders in the Northern San Joaquin
Valley, won’t continue as chairwoman of the State Water
Resources Control Board. Gov. Gavin Newsom named Joaquin
Esquivel as chairman of the powerful water regulatory board.
… Laurel Firestone, co-founder of the Community Water
Center, was appointed as the replacement for Marcus.

contaminated with nitrates.
Of the 517 groundwater basins and subbasins in California,

About 1 million Californians can’t safely drink their tap
water. Approximately 300 water systems in California
currently have contamination issues ranging from arsenic to lead

disgrace that demands immediate state action.
California’s San Joaquin River Delta is in danger of being
overrun by voracious beagle-sized rodents. The state has a plan
to deal with them, but it’s going to take a lot of time and
money. Nutria, a large South American rodent, have become an
invasive species in several states, including Louisiana,
Maryland and Oregon.
While campaigning for president in 2016, Donald Trump promised

most aggressive steps to date to fulfill that promise Tuesday
by proposing to relax environmental regulations governing how
water is shared between fish and human uses throughout the
After more than a decade of drafting and editing, California is
poised to finally update its wetlands regulations this spring.
The effort, which began after a pair of Supreme Court decisions
limited federal wetlands protections, could be finalized just
in time to insulate the state from a Trump administration
proposal restricting which wetlands and waterways are protected
by the Clean Water Act.
By this time next year, 21 critically over-drafted groundwater
basins in California must submit plans to the state’s
Department of Water Resources for how to bring their basins
back into balance. With this major deadline looming, it’s
crunch time for water managers and their consultants – some of
whom will begin releasing draft plans in the next six to eight
months seeking required public comments.
Congressmen John Garamendi and Doug LaMalfa have reintroduced
legislation to provide farmers access to discounted rates under
the National Flood Insurance Program. The
bipartisan Flood Insurance for Farmers Act of
2019 (H.R.830) would also lift the de
facto federal prohibition on construction and repair of
agricultural structures in high flood-risk areas designated by
the Federal Emergency Management Agency.

Maintaining functional wetlands in a 21st-century landscape
dominated by agriculture and cities requires a host of hard and
soft infrastructures. Canals, pumps, and sluice gates provide
critical life support, and the lands are irrigated and tilled
in seasonal cycles to essentially farm wildlife. Reams of laws
and regulations scaffold the system.
Last week, in the third meeting of the Board of Directors of
the San Lorenzo Valley Water District … the board voted 4-1
for a permanent ban on the use of glyphosate pesticides by the
district, keeping a campaign promise that remained
controversial right up to the board’s vote. “The residents in
our district have spoken — they do not want glyphosate … and we
don’t really know the true effects of glyphosate — how it will
affect all the little creatures in sensitive habitat,” said
Louis Henry, the newly appointed board chair.
“The judiciary is the safeguard of our liberty and of our
property under the Constitution,” said U.S. Supreme Court
Justice Charles Evans Hughes in Elimra, New York in 1907. That

Water is becoming a scarce resource in many parts of the world.
Water tables have been falling in many regions for decades,
particularly in areas with intensive agriculture. Wells are
going dry and there are few long-term solutions available — a
common stopgap has been to drill deeper wells. This is exactly
what happened in California’s Central Valley. The recent
drought there prompted drilling of deeper and deeper water
wells to support irrigated agriculture.
Most of the first American settlers of the Delta came to
California to quickly acquire a pile of gold. Few
succeeded in the placers, but some recognized the
agricultural potential and decided to build farms and
futures in the Golden State. One such visionary was my
great great grandfather, Reverend Daniel Shaw Stuart.
When it comes to water, the lifeblood of the Central Valley,
Democrats don’t have all the answers. So says freshman
Representative Josh Harder, suddenly one of the most powerful
Democrats in these parts. … “We need to make sure we’re
all working together to advance the agenda of the Central
Valley,” continued Harder, 32, of Turlock. “I was very
encouraged to see some of the measures the Trump
administration put forward on water.”
The State Water Resources Control Board has proposed flow
requirements for rivers that feed the Delta based on a
percentage of ‘unimpaired flows… If approved, this
‘unimpaired flows’ approach would have significant impacts on
farms, communities throughout California and the environment.
We join many other water agencies in our belief that

One in seven Americans drink from private wells, according to
the U.S. Geological Survey. Nitrate concentrations rose
significantly in 21% of regions where USGS researchers tested
groundwater from 2002 through 2012, compared with the 13 prior
years. … “The worst-kept secret is how vulnerable
private wells are to agricultural runoff,” says David Cwiertny,
director of the University of Iowa’s Center for Health Effects
of Environmental Contamination.
Since taking office Jan. 7, Gov. Gavin Newsom has not
indicated how he intends to approach one of the state’s most
pressing issues: water. Newsom should signal that
it’s a new day in California water politics by embracing
a more-sustainable water policy that emphasizes
conservation and creation of vast supplies of renewable
water. The first step should be to announce the
twin-tunnels effort is dead.
California’s new governor looked at the rainfall and saw
millions of dollars in uncollected water taxes going right down
the drain. In one of his first moves as chief executive, Newsom
declared that he wants to tax the state’s drinking water, in
order to give poor people access to safe and affordable water.
I guess this is his idea of trickle-down economics.
More than ever, water’s true value as a finite and precious
resource is starting to be realised, and a growing number of
investors are paying attention. There are plenty of examples of
water risk. Campbell Soup Company took a hit in its quarterly
earnings recently, due to an acquisition of a California fresh
food company that was pummeled by the California drought.
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 confluence of California’s two great rivers, the Sacramento
and the San Joaquin, creates the largest estuary on the West
Coast of the Americas. Those of us who live here call it,
simply, the Delta. It is part of my very fiber, and it is
essential to California’s future. That’s why we must save it.
Wells are going dry and there are few long-term solutions
available — a common stopgap has been to drill deeper wells.
This is exactly what happened in California’s Central Valley.
The recent drought there prompted drilling of deeper and deeper
water wells to support irrigated agriculture. Groundwater
supplies around the world are being threatened by excessive
pumping, but drilling deeper wells is not a long-term solution.
A better solution is to manage water use and avoid excessive
declines in groundwater levels.

As his term as governor drew to a close, Jerry Brown brokered a
historic agreement among farms and cities to surrender billions
of gallons of water to help ailing fish. He also made two big
water deals with the Trump administration. It added up to
a dizzying display of deal-making. Yet as Gavin Newsom takes
over as governor, the state of water in California seems as
unsettled as ever.

percent of all fruits, nuts and vegetables consumed throughout
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.
Farmers in the Central Valley are broiling about California’s plan to increase flows in the Sacramento and San Joaquin river systems to help struggling salmon runs avoid extinction. But in one corner of the fertile breadbasket, River Garden Farms is taking part in some extraordinary efforts to provide the embattled fish with refuge from predators and enough food to eat.
And while there is no direct benefit to one farm’s voluntary actions, the belief is what’s good for the fish is good for the farmers.
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.

New water storage is the holy grail
primarily for agricultural interests in California, and in 2014
the door to achieving long-held ambitions opened with the passage
1, which included $2.7 billion for the public benefits
portion of new reservoirs and groundwater storage projects. The
statute stipulated that the money is specifically for the
benefits that a new storage project would offer to the ecosystem,
water quality, flood control, emergency response and recreation.
The many wells that nourish the farms of the Central Valley are
not only pumping so much water from the ground that the land is
sinking, they’re creating a dangerous vacuum where arsenic can
slip in, new research shows. Scientists at Stanford
University are warning if heavy groundwater pumping continues,
water supplies for dozens of communities as well as billions of
dollars of irrigated crops are at risk of contamination.
