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
Bay.
… What about a dam and giant lake on the northern edge of
Fresno? It almost happened. Today on KVPR’s Central Valley
Roots, the story behind the planned Fig Garden Dam and
Reservoir. The Central Valley Project was a big part of
President Franklin Delano Roosevelt’s New Deal. It led to the
construction of facilities like Friant and Shasta Dams. But the
vision didn’t end with FDR. The Bureau of Reclamation developed
plans for more dams and reservoirs, including one on the San
Joaquin River near Highway 99 – the planned Fig Garden Dam and
Reservoir. The lake would have been a key link in a new chain
of canals on the east side of the valley, from Folsom to Fresno
to Bakersfield.
Tulare Lake used to the largest body of freshwater west of the
Mississippi. It disappeared, after farmers and cities diverted
its waterflows with dams and canals. But long ago there was an
even larger lake in the region. Today on KVPR’s Central Valley
Roots – the story of what happened to Lake Corcoran. Imagine a
map of the entire Central Valley from Bakersfield to north of
Sacramento – all underwater. If you went back, say 1 million
years ago that’s pretty much what you would have seen,
something geologists today call Lake Corcoran. Back then, the
Valley didn’t drain into San Francisco Bay. Instead, geologists
believe Lake Corcoran actually drained from the south into the
Salinas River, flowing all the way to Monterey Bay.
Recharging more water from large winter and spring storms into
California’s underground aquifers is a powerful tool for
reducing groundwater overdraft, improving drought preparedness,
and limiting flood risk to downstream communities. The banner
wet year of 2023 saw considerable progress on this front. The
state facilitated the recharge of flood flows through new
executive orders and legislation (SB 122), and numerous local
programs got more water into the ground. In the water-scarce
San Joaquin Valley, our recent survey found that recharge had
increased by 17% since 2017, another very wet year. As we enter
another storm season, stakeholders are focused on understanding
a key question: how to build on this success, while ensuring
that enough water stays in rivers to protect the environment
and the rights of downstream water users?
A heated election for a board seat at the Laguna Irrigation
District is stuck in a tie with both candidates having garnered
101 votes. Wes Harmon, a local well driller, challenged
incumbent Frank Zonneveld, Laguna’s board president.
Zonneveld had no comment on the race and only wrote in an email
that whatever happens next is, “way above my paygrade.”
Staff at the Fresno County Registrar of Voters met on Wednesday
morning to discuss what processes will take place in the event
of tied races.Typically there will be a recount, according to
department staff. But as of Wednesday morning, no official
process had been disclosed.
… [Matthew] Lees and senior researcher Rosemary Knight,
Ph.D., from Stanford’s Doerr School of Sustainability, … have
some predictions for the future. In a newly released study, the
Stanford team combines satellite data from multiple decades
with readings from ground-based GPS stations. The result is a
kind of three-dimensional map, pinpointing the areas most
affected by the over-pumping of groundwater in the Central
Valley and the rate they’re still sinking. … Levels have been
continuing to drop as much as a foot in many of the years since
2006. But with those measurements, comes the beginning of a
possible solution. When we first met Professor Knight several
years ago, her team was pinging the valley floor with
electromagnetic antennas suspended from a helicopter, mapping
California’s underground aquafers and the soils that run
through them. The goal: to identify super porous basins and
farmland that could be flooded or pumped with diverted water to
recharge the sinking aquifers. She says adding in the new
precision mapping data could help do that, and more.
… The Sacramento perch is unique. … Once highly abundant in
California’s Central Valley, Salinas and Pajaro Rivers, and
Clear Lake, it is now absent from its native waters.
… man-made water infrastructure, such as reservoirs,
ponds, culverts, and canals can provide habitat for native
species at risk, even if the modified areas have not been
historically considered native fish habitat. In an era when
ecosystem-wide change is sometimes irreversible, conservation
should be geared towards reconciliation rather than returning
to unattainable historic conditions. Thinking outside the box
on conventional conservation is key
The Bureau of Reclamation and the San Luis & Delta-Mendota
Water Authority [on Nov. 13] announced a negotiated
consensus has been met for the B.F. Sisk Dam Raise and
Reservoir Expansion Project. The joint project creates an
additional 130,000 acre-feet of storage space in San Luis
Reservoir, the nation’s largest off-stream reservoir, producing
additional water supply for two million people, over one
million acres of farmland and 135,000 acres of Pacific Flyway
wetlands and critical wildlife habitat. Reclamation signed the
Record of Decision for the project on Oct. 20, 2023, the first
approval of a major water storage project in California since
2011.
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.
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.
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.
Land and waterway managers labored
hard over the course of a century to control California’s unruly
rivers by building dams and levees to slow and contain their
water. Now, farmers, environmentalists and agencies are undoing
some of that work as part of an accelerating campaign to restore
the state’s major floodplains.
Biologists have designed a variety
of unique experiments in the past decade to demonstrate the
benefits that floodplains provide for small fish. Tracking
studies have used acoustic tags to show that chinook salmon
smolts with access to inundated fields are more likely than their
river-bound cohorts to reach the Pacific Ocean. This is because
the richness of floodplains offers a vital buffet of nourishment
on which young salmon can capitalize, supercharging their growth
and leading to bigger, stronger smolts.
A government agency that controls much of California’s water
supply released its initial allocation for 2021, and the
numbers reinforced fears that the state is falling into another
drought. The U.S. Bureau of Reclamation said Tuesday that most
of the water agencies that rely on the Central Valley Project
will get just 5% of their contract supply, a dismally low
number. Although the figure could grow if California gets more
rain and snow, the allocation comes amid fresh weather
forecasts suggesting the dry winter is continuing. The National
Weather Service says the Sacramento Valley will be warm and
windy the next few days, with no rain in the forecast.
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.
Deep, throaty cadenced calls —
sounding like an off-key bassoon — echo over the grasslands,
farmers’ fields and wetlands starting in late September of each
year. They mark the annual return of sandhill cranes to the
Cosumnes River Preserve,
46,000 acres located 20 miles south of Sacramento on the edge of
the Sacramento-San Joaquin Delta.
Shortly after taking office in 2019,
Gov. Gavin Newsom called on state agencies to deliver a Water
Resilience Portfolio to meet California’s urgent challenges —
unsafe drinking water, flood and drought risks from a changing
climate, severely depleted groundwater aquifers and native fish
populations threatened with extinction.
Within days, he appointed Nancy Vogel, a former journalist and
veteran water communicator, as director of the Governor’s Water
Portfolio Program to help shepherd the monumental task of
compiling all the information necessary for the portfolio. The
three state agencies tasked with preparing the document delivered
the draft Water Resilience Portfolio Jan. 3. The document, which
Vogel said will help guide policy and investment decisions
related to water resilience, is nearing the end of its comment
period, which goes through Friday, Feb. 7.
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.
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.
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.
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.
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.
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
3-5, you will meet farmers who will explain how they prepare
the fields, irrigate their crops and harvest the produce that
helps feed the nation and beyond. We also will drive through
hundreds of miles of farmland and visit the rivers, dams,
reservoirs and groundwater wells that provide the water.
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.
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.
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
of Proposition
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.
For more than 100 years, invasive
species have made the Sacramento-San Joaquin Delta their home,
disrupting the ecosystem and costing millions of dollars annually
in remediation.
The latest invader is the nutria, a large rodent native to South
America that causes concern because of its propensity to devour
every bit of vegetation in sight and destabilize levees by
burrowing into them. Wildlife officials are trapping the animal
and trying to learn the extent of its infestation.
Deep, throaty cadenced calls —
sounding like an off-key bassoon — echo over the grasslands,
farmers’ fields and wetlands starting in late September of each
year. They mark the annual return of sandhill cranes to the
Cosumnes River Preserve,
46,000 acres located 20 miles south of Sacramento on the edge of
the Sacramento-San Joaquin Delta.
Along the banks of the
Sacramento-San Joaquin Delta in Oakley, about 50 miles southwest
of Sacramento, is a park that harkens back to the days when the
Delta lured Native Americans, Spanish explorers, French fur
trappers, and later farmers to its abundant wildlife and rich
soil.
That historical Delta was an enormous marsh linked to the two
freshwater rivers entering from the north and south, and tidal
flows coming from the San Francisco Bay. After the Gold Rush,
settlers began building levees and farms, changing the landscape
and altering the habitat.
Despite the heat that often
accompanies debates over setting aside water for the environment,
there are instances where California stakeholders have forged
agreements to provide guaranteed water for fish. Here are two
examples cited by the Public Policy Institute of California in
its report arguing for an environmental water right.

The recent deluge has led to changes in drought conditions in
some areas of California and even public scrutiny of the
possibility that the drought is over. Many eyes are focused on
the San Joaquin Valley, one of the areas hardest hit by reduced
surface water supplies. On our Central Valley Tour, March
8-10, we will visit key water delivery and storage sites in the
San Joaquin Valley, including Friant Dam and Millerton Lake
on the San Joaquin River.
The San Joaquin Valley has been hit hard by the six-year drought
and related surface water cutbacks. Some land has been fallowed
and groundwater pumping has increased. What does this year hold?
Will these recent heavy storms provide enough surface water for
improved water deliveries?
Your best opportunity to see and understand this vital
agricultural region of California is to join us on our annual
Central Valley Tour,
March 8-10.
ARkStorm stands for an atmospheric
river (“AR”) that carries precipitation levels expected to occur
once every 1,000 years (“k”). The concept was presented in a 2011
report by the U.S. Geological Survey (USGS) intended to elevate
the visibility of the very real threats to human life, property
and ecosystems posed by extreme storms on the West Coast.
Excess salinity poses a growing
threat to food production, drinking water quality and public
health. Salts increase the cost of urban drinking water and
wastewater treatment, which are paid for by residents and
businesses. Increasing salinity is likely the largest long-term
chronic water quality impairment to surface and groundwater in California’s Central
Valley.
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.”

Salt. In a small amount, it’s a gift from nature. But any doctor
will tell you, if you take in too much salt, you’ll start to have
health problems. The same negative effect is happening to land in
the Central Valley. The problem scientists call “salinity” poses
a growing threat to our food supply, our drinking water quality
and our way of life. The problem of salt buildup and potential –
but costly – solutions are highlighted in this 2008 public
television documentary narrated by comedian Paul Rodriguez.

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.

Travel across the state on Amtrak’s famed California
Zephyr, from the edge of sparkling San Francisco Bay,
through the meandering channels of the Delta, past rich Central
Valley farmland, growing cities, historic mining areas and into
the Sierra Nevada mountain range.
With the dual threats of aging levees and anticipated rising sea levels,
floodplains — low
areas along waterways that flood during wet years — are
increasingly at the forefront of many public policy and water
issues in California.
Adding to the challenges, many floodplains have been heavily
developed and are home to major cities such as Sacramento. Large
parts of California’s valleys are historic floodplains as well.
The Pacific Flyway is one of four
major North American migration routes for birds, especially
waterbirds, and stretches from Alaska in the north
to Patagonia in South America.
Each year, birds follow ancestral patterns as they travel the
flyway on their annual north-south migration. Along the way, they
need stopover sites such as wetlands with suitable habitat and
food supplies. In California, 95 percent of historic
wetlands have been lost, yet the Central Valley hosts some of the
world’s largest populations of wintering birds.
The Mendota Pool, located at the confluence of the
San Joaquin River and Kings River in California’s Central
Valley, is the terminus of a long journey for water from the
Sacramento River.
After being diverted, the Sacramento River water heads south from
the Sacramento
San Joaquin Delta via the 117-mile long Delta-Mendota Canal.
Environmental concerns have closely followed California’s
development of water resources since its earliest days as a
state.
Early miners harnessed water to dislodge gold through hydraulic
mining. Debris resulting from these mining practices washed down
in rivers and streams, choking them and harming aquatic life and
causing flooding.
In the Central Valley, wetlands—partly or seasonally saturated
land that supports aquatic life and distinct ecosystems— provide
critical habitat for a variety of wildlife.
This issue of Western Water looks at the BDCP and the
Coalition to Support Delta Projects, issues that are aimed at
improving the health and safety of the Delta while solidifying
California’s long-term water supply reliability.
This printed issue of Western Water features a
roundtable discussion with Anthony Saracino, a water resources
consultant; Martha Davis, executive manager of policy development
with the Inland Empire Utilities Agency and senior policy advisor
to the Delta Stewardship Council; Stuart Leavenworth, editorial
page editor of The Sacramento Bee and Ellen Hanak, co-director of
research and senior fellow at the Public Policy Institute of
California.
This printed issue of Western Water looks at hydraulic
fracturing, or “fracking,” in California. Much of the information
in the article was presented at a conference hosted by the
Groundwater Resources Association of California.
This printed copy of Western Water examines the challenges facing
small water systems, including drought preparedness, limited
operating expenses and the hurdles of complying with costlier
regulations. Much of the article is based on presentations at the
November 2007 Small Systems Conference sponsored by the Water
Education Foundation and the California Department of Water
Resources.
This issue of Western Water examines the extent to
which California faces a disaster equal to or greater than the
New Orleans floods and the steps being taken to recognize and
address the shortcomings of the flood control system in the
Central Valley and the Delta, which is of critical importance
because of its role in providing water to 22 million people.
Complicating matters are the state’s skyrocketing pace of growth
coupled with an inherently difficult process of obtaining secure,
long-term funds for levee repairs and continued maintenance.
This issue of Western Water analyzes northern California’s
extensive flood control system – it’ history, current concerns,
the Paterno decision and how experts are re-thinking the concept
of flood management.
