California has been the nation’s
leading agricultural and dairy state for the past 50 years. The
state’s 80,500 farms and ranches produce more than 400 different
agricultural products. These products generated a record $44.7
billion in sales value in 2012, accounting for 11.3 percent of
the US total.
Breaking down the state’s agricultural role in the country,
California produces 21 percent of the nation’s milk supply, 23
percent of its cheese and 92 percent of all grapes. The state
also produces half of all domestically-grown fruits, nuts and
vegetables, including some products, such as almonds, walnuts,
artichokes, persimmons and pomegranates, of which 99 percent are
grown in California.
Overall, about 3 percent of employment in the state is directly
or indirectly related to agriculture.
The Bureau of Reclamation is launching the Sustainable Water
for Agriculture Pilots (SWAP) Program that will test innovative
crops and practices to significantly reduce agricultural water
use at low to moderate costs. These projects will keep the
farmland in production while conserving water. Reclamation has
$6.5 million available this year for this new program through
the Inflation Reduction Act. “This innovative program seeks to
preserve farming and agricultural activities in water stressed
areas,” said Policy Advisor James Langhenry. “If the
demonstration projects are successful, the innovative crops or
practices can be used over time to ensure families can continue
to farm while receiving compensation and strengthening water
security in the West.”
There are significant myths regarding almonds. Most of it is
about how they use too much water, but they get four crops from
every drop of water. They’re very efficient. Clarice Turner is
president and CEO of the Almond Board of California. “Part of
what we’re doing is just making sure that the public is aware
of the facts, Turner said. “And by the way, it’s not
marketing hype because we are a quasi-government overseen by
the USDA. Everything we publish has to be fact-based. That’s
coming from at least three peer-reviewed academic studies in
the traditional process. That’s how we get our information,”
she said. “It’s unfortunate that people think almonds use too
much water. A statement like this grows arms and legs.
When you irrigate almonds, you get four crops per drop—
There’s the kernel we eat, which grows inside a woody shell,
fuzzy outer hull, and the tree. The trees store tons of carbon
each year, the shells become livestock bedding, and the hulls
are nutritious dairy feed, reducing the water needed to grow
other feed crops,” explained Turner.
… One major environmental concern associated with cannabis
cultivation is the excessive demand for water. Cannabis plants
require a large amount of water, particularly in arid regions
where many grow operations are located. Data from the
California Department of Water Resources show that legal
cannabis cultivation can consume more water than many other
crops, which puts additional strain on already limited water
supplies, especially in drought-stricken areas. In response,
certain states have begun adopting regulations to mitigate
water usage by requiring specific water allocations for
cannabis farms. For instance, California, which produces nearly
70% of the nation’s cannabis, instituted stricter water
regulations in response to prolonged droughts. Under the
Sustainable Groundwater Management Act, cannabis cultivators
must now develop and implement water conservation plans that
align with broader resource management strategies.
Alfalfa has a lot of impressive features when it comes to water
usage. And despite being a major water user, alfalfa is also a
major food producer. At least, that is how Dan Putnam defended
the number one field crop in the Golden State against claims of
water overconsumption at the California Alfalfa & Forage
Symposium last month in Sparks, Nev. At the symposium, Putnam
explained alfalfa’s value as a productive and flexible water
consumer. The extension professor emeritus with the University
of California, Davis, contended that deficit irrigation — not
fallowing or eliminating alfalfa stands — may be the best tool
to address the water crisis in regions where robust forage
production occurs in the West and water availability is highly
variable.
… California’s southern Central valley is a
particularly popular spot for pistachio farming. The dryness of
desert-like conditions during the summer months is no deterrent
for the nut. … “Pistachios also don’t need the same
high-quality water that something like almonds do,” said Darwin
Inman, vice-president of sales and marketing at Horizon Nut
Company. “They’re a fairly stout tree. They can get away with a
little bit less quality of water, irrigation water.”…
The diminished need for water means that farmers have more
readily embraced pistachios, including when it comes to the
nut’s biggest rival, almonds, which generated nearly $4bn in
California last year. More growers are opting to dedicate land
to drought-tolerant pistachios over thirsty almond trees.
Proposed vineyard wastewater regulations provoked a major hue
and cry among Sonoma and Mendocino growers when government
officials introduced them in 2022. On Dec. 4, 2024, state
water board officials announced a new plan they hoped would
better address growers who farm 65,000 acres of planted
vineyards–more than 10 percent of the 550,000 acres planted in
the state (see meeting slides here). But the
proposed revisions were still found wanting, locals said.
County leaders pointed out the water board itself still has not
defined standards for Russian River sediment and said vineyards
are not the ones to blame for water issues. The fault lies
instead with rural roads and the federal and Sonoma County
authorities who oversee Lake Mendocino, they said.
Two years ago, California water regulators were stunned to
learn that a major river in the San Joaquin Valley had stopped
flowing. The waterway ran dry for 5 miles, leaving young fish
stranded in muddy pools, birds fleeing to new homes, and
paddlers, waterfront property owners and farmers gripped with
frustration. In a state partly defined by its thirst for water,
the emptying of the Merced River for four months in 2022
remained something of a mystery. Fed by the snowy peaks of the
Sierra, the Merced has long been heavily pumped for
agriculture, and its levels often dip considerably during
droughts. Yet California generally restricts water draws to
keep at least some flow moving downstream. An investigation
that state water regulators are just finishing into why the
river dried up offers some insight: While water users clearly
drew out more water than was healthy for the Merced, the
California State Water Resources Control Board found that the
users were largely within their legal rights to do so,
highlighting a fundamental problem with the state’s regulatory
system.
For decades, California’s water debates have centered on a
familiar tension: agriculture versus urban consumption.
Agriculture, which consumes 80% of the state’s developed water
supply, has long dominated discussions about conservation and
efficiency. Yet, a new contender is emerging, one poised to
dwarf agriculture in water demand and reshape the state’s water
future: artificial intelligence (AI). … For decades,
agriculture has been framed as the primary focus of water
conservation efforts, with farmers frequently cast as both
stewards and villains of California’s strained water
resources. While agriculture dominates the present, the
future tells a different story. AI, fueled by data centers
housing millions of servers, is on a trajectory to become a
massive water consumer. These data centers rely heavily on
water-intensive cooling systems to maintain the functionality
of high-performance chips that power AI applications. —Written by Dean Florez, past senator from Central
Valley and a member of the California Air Resources Board
There is almost no disagreement any longer among scientists
that climate change is a reality and that its effects are
already upon us. A number of researchers at Cal State Monterey
Bay are engaged in work that is either measuring those effects
or finding ways to combat them. Among the studies are those
looking at off-gassing from agricultural fields, warmer ocean
water’s impact on coral reefs, and wildlife preservation.
… Arun Jani, assistant professor in the Biology and
Chemistry department, is trying to determine the optimum use of
nitrogen as a fertilizer in agricultural fields in the hope of
reducing current levels. His projects run from fields near
Soledad to test plots in Watsonville. In addition to
decreased fertilizer use, Jani is also evaluating the effects
of using a material called biochar in the soil and determining
ideal crop rotations. … Nitrogen fertilizers not only produce
nitrous oxide gas, but they can also leach into groundwater and
raise levels of nitrate, a harmful chemical. The industry
standard for nitrogen fertilizers is to use 150 pounds per
acre. Jani’s studies have shown that much less of the chemical
can be used effectively for area crops.
Coby Hunt’s farm field near the southeast Utah town of Green
River would normally be filled with alfalfa growing up to his
knees. This year, however, it was barren — pale gray dirt
cracking under the late summer sun. The only green things were
scraggly scraps of whatever accidental plants somehow survived
without irrigation. … “It hurts,” he said as he surveyed
the desolate field. “But there’s also a benefit of it looking
like this, right?” That benefit is taking the water he could
have used to irrigate his land and leaving it in the nearby
Green River, which flows to the increasingly strained Colorado
River. … Across Utah, farmers are experimenting with ways to
tighten their water use as agriculture, drought and population
growth collide to put pressure on the state’s limited water
resources. Some are installing more efficient irrigation
technology. Others are testing unconventional crops. In Hunt’s
case, he’s taking some of his farmland out of commission
entirely — for a time and for a price.
… The Imperial Irrigation District uses more water from the
Colorado River than any other single entity – farm district,
city, or otherwise – from Wyoming to Mexico. As climate change
shrinks the river’s supplies, its biggest users are facing
increasing pressure to cut back on their demand. … Over the
course of three years, [the federal government] agreed to send
more than $500 million to the district to use less water and
leave it in Lake Mead, the nation’s largest reservoir. That
money comes from the Biden Administration’s Inflation Reduction
Act. Water leaders in the West and Washington D.C. alike have
lauded the effort as a pivotal way to boost the reservoir,
which has dropped to all-time low levels in recent years.
Similar spending has saved water on farms and tribal land
across the region. It has also made city utilities more
efficient. But now, on the cusp of Donald Trump’s return to the
White House, those who use the river’s water are worried that
funding could disappear.
The Tulare County Farm Bureau intends to send a “strong
message” to the state by pledging $10,000 to its counterpart,
the Kings County Farm Bureau, in the latter’s legal fight
against groundwater sanctions issued by the Water Resources
Control Board. “We felt it was still a warranted action to lend
support to our neighboring county,” said Tricia Stever
Blattler, executive director for the Tulare farm bureau. The
farm bureau’s most recent newsletter called the donation a
“strong message to the state water board that we are committed
to supporting this legal battle in hopes it brings positive
change to the SGMA process for all landowners involved.”
Seeking to prevent the California State Water Resources Control
Board from stepping in to regulate groundwater in critically
overdrafted subbasins, local agencies are working to correct
deficiencies in their plans to protect groundwater. With
groundwater sustainability agencies formed and groundwater
sustainability plans evaluated, the state water board has moved
to implement the 2014 Sustainable Groundwater Management Act,
or SGMA. … Under probation, groundwater extractors in
the Tulare Lake subbasin face annual fees of $300 per well and
$20 per acre-foot pumped, plus a late reporting fee of 25%.
SGMA also requires well owners to file annual groundwater
extraction reports.
Catastrophic weather events wreaked havoc on U.S. agriculture
last year, causing nearly $22 billion in crop and rangeland
losses, according to the American Farm Bureau Federation.
California accounted for $1.14 billion of that figure,
including nearly $880 million in damages from severe storms and
flooding. The figures represent a significant shift from
previous years, when drought and wildfires were California’s
biggest challenges. Since then, atmospheric rivers, Tropical
Storm Hilary and other weather events battered our farming
communities. - Written by Matthew Viohl, director of federal
policy for the California Farm Bureau

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.
Water is expensive – and securing enough money to ensure
reliability and efficiency of the state’s water systems and
ecosystems is a constant challenge.
In 2014, California voters approved Proposition 1, authorizing a
$7.5 billion bond to fund water projects throughout the state.
This included investments in water storage, watershed protection
and restoration, groundwater sustainability and drinking water
protection.
California agriculture is going to have to learn to live with the
impacts of climate change and work toward reducing its
contributions of greenhouse gas emissions, a Yolo County walnut
grower said at the Jan. 26 California Climate Change Symposium in
Sacramento.
“I don’t believe we are going to be able to adapt our way out of
climate change,” said Russ Lester, co-owner of Dixon Ridge Farms
in Winters. “We need to mitigate for it. It won’t solve the
problem but it can slow it down.”
From the Greek “xeros” and Middle Dutch “scap,”
xeriscape was coined
in 1978 and literally translates to “dry scene.”
Xeriscaping, by extension, is making an environment which can
tolerate dryness. This involves installing drought-resistant and
slow-growing plants to reduce water use.
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.
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.
California’s severe drought has put its water rights system under
scrutiny, raising the question whether a complete overhaul is
necessary to better allocate water use.

Introduction
California’s severe drought has put its water rights system under
scrutiny, raising the question whether a complete overhaul is
necessary to better allocate water use.
This 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 3-day, 2-night tour, which we do every spring,
travels the length of the San Joaquin Valley, giving participants
a clear understanding of the State Water Project and Central
Valley Project.
Located just north of Fresno, the
Friant Dam helps deliver water as it runs towards the Merced River, though its
environmental impacts have caused controversy.
This printed issue of Western Water examines
agricultural water use – its successes, the planned state
regulation to quantify its efficiency and the potential for
greater savings.
This Western Water looks at proposed new measures to deal with
the century-old problem of salinity with a special focus on San
Joaquin Valley farms and cities.
The Reclamation Act of 1902, which could arguably be described as
a progression of the credo, Manifest Destiny, transformed the
West. This issue of Western Water provides a glimpse of the past
100 years of the Reclamation Act, from the early visionaries who
sought to turn the arid West into productive farmland, to the
modern day task of providing a limited amount of water to homes,
farms and the environment. Included are discussions of various
Bureau projects and what the next century may bring in terms of
challenges and success.
30-minute DVD that traces the history of the U.S. Bureau of
Reclamation and its role in the development of the West. Includes
extensive historic footage of farming and the construction of

Our 24×36-inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
This beautiful 24×36 inch poster, suitable for framing, features
a map of the San Joaquin River. The map text focuses on the San

rises to form clouds, and returns to the earth as precipitation.
Excellent for elementary school classroom use.
With irrigation projects that import water, farmers have
transformed millions of acres of land into highly productive
fields and orchards. But the dry climate that provides an almost
year-round farming season can hasten salt build up in soils. The
build-up of salts in poorly drained soils can decrease crop
productivity, and there are links between drainage water from
irrigated fields and harmful impacts on fish and wildlife.

relationships with one of the West’s largest rivers — and a
vast watershed that hosts one of the nation’s oldest and
largest reclamation projects.
There are two constants regarding agricultural water use –
growers will continue to come up with ever more efficient and
innovative ways to use water and they will always be pressed to
do more.
It’s safe to say the matter will not be settled anytime soon,
given all the complexities that are a part of the water use
picture today. While officials and stakeholders grapple to find a
lasting solution to California’s water problems that balances
environmental and economic needs, those who grow food and fiber
for a living do so amid a host of challenges.
Land retirement is a practice that takes agricultural lands out
of production due to poor drainage and soils containing high
levels of salt and selenium (a mineral found in soil).
Typically, landowners are paid to retire land. The purchaser,
often a local water district, then places a deed restriction on
the land to prevent growing crops with irrigation water (a source
of salt). Growers in some cases may continue to farm using rain
water, a method known as dry farming.
Evaporation ponds contain agricultural drainage water and are
used when agricultural growers do not have access to rivers for
drainage disposal.
Drainage water is the only source of water in many of these
ponds, resulting in extremely high concentrations of salts.
Concentrations of other trace elements such as selenium are also
elevated in evaporation basins, with a wide degree of variability
among basins.
Such ponds resemble wetland areas that birds use for nesting and
feeding grounds and may pose risks to waterfowl and shorebirds.
The Coachella Valley in Southern California’s Inland Empire is
one of several valleys throughout the state with a water district
established to support agriculture.
Like the others, the Coachella Valley Water District in Riverside
County delivers water to arid agricultural lands and constructs,
operates and maintains a regional agricultural drainage system.
These systems collect drainage water from individual farm drain
outlets and convey the water to a point of reuse, disposal or
dilution.
