Drought— an extended period of limited or no precipitation— is a
fact of life in California and the West, with water resources
following boom-and-bust patterns.
No portion of the West has been immune to drought during the last
century and drought occurs with much greater frequency in the
West than in other regions of the country.
Most of the West experiences what is classified as severe to
extreme drought more than 10 percent of the time, and a
significant portion of the region experiences severe to extreme
drought more than 15 percent of the time, according to the
National Drought Mitigation Center.
Experts who have studied recent droughts say a drought occurs
about once every 10 years somewhere in the United States.
Droughts are believed to be the most costly of all natural
disasters because of their widespread effects on agriculture and
related industries, as well as on urbanized areas. One of those
decennial droughts could cost as much as $38 billion, according
to one estimate.
Because droughts cannot be prevented, experts are looking for
better ways to forecast them and new approaches to managing
droughts when they occur.
The water cycle is the movement of water on the planet — from
falling as precipitation, such as rain, ice or snow, to being
absorbed in the soil or flowing into groundwater and streams
and then being evaporated to start all over again. Research by
scientists from the U.S. Geological Survey shows water has been
moving more quickly and intensely through the various stages of
the cycle, according to NASA’s Earth Observatory.
The report estimates there are a cluster of major California
crops that are particularly vulnerable to extreme temperature
changes: wine grapes, lettuce, almonds, strawberries, table
grapes, hay, oranges, cotton, tomatoes, walnuts, avocados, and
pistachios. Specifically, avocado production in California
could fall 40 percent by 2050 due to climate change factors.
Moderator Kathleen Schock got an update on how the work is
progressing locally from Gary Serrato, executive director of
the North Kings Groundwater Sustainability Agency, Christina
Beckstead, executive director of Madera County Farm Bureau, and

The center, being built at North Natomas Regional Park, will
feature the city’s first 50-meter competition pool with 13

More than 90% of U.S. wine comes from California, despite
growth in other states’ production, and it’s putting a strain
on the environment. Throughout the region, wine producers say
they’re striving to save water and use less pesticides, among
other measures aimed at sustainable growing, as they face the
challenges brought on by the advance of climate change.
By 2030, the Carpinteria Valley Water District estimates that
on a dry year, the deficit could be as high as 1,550 acre
feet—enough to fill 775 Olympic-sized swimming pools, or serve
the average yearly use of 6,200 local households. In response
to the shortfall, CVWD proposes a $25 million project to take
wastewater that has been cleaned, purify it and then inject it
into the groundwater basin…
Jennifer Gilden, the Pacific Fishery Management Council’s staff
officer for outreach, habitat and legislation, said the ocean

Water is the lifeblood of the Sacramento Valley. Yet, the best
methods for storing and using the precious resource are often
elusive. A new water system in operation in Roseville treats
underground aquifers like a bank, making deposits in times of
surplus for withdrawal in times of drought.
The project’s ocean-friendly technology has won praise from the
same environmentalists fighting a desalter plant proposed by
Poseidon Water for Huntington Beach, one of several things that
distinguish the south county plant from the more controversial
project to the north. … But the price tag is steep for a
district that serves a relatively modest population of 35,000,
just over 1% of the county.
The newly formed water market would create a place where
farmers in the Rosedale district can buy and sell water based
on their needs. So if one farmer has too much for his crops in
a certain year, he’d be able to sell it on the market to
another who might not have enough.
During our Edge of Drought Tour Aug. 27-29, we’ll visit an
atmospheric river observatory in Santa Barbara that
specifically monitors the meteorological phenomenon and also
visit Lopez Lake to hear from the County of San Luis Obispo on
their cloud seeding efforts.
The Coleman National Fish Hatchery is expecting good returns of
their fish in the foreseeable future after a few lean years of
comebacks. … Mother Nature worked with the hatchery this year
providing high water levels and spring storms, said Galyean.
When nature was not working in the hatchery’s favor was during
the recent drought.
High-tech firms like Ceres, Prospera, Farmers Edge, and the
Climate Corporation are using artificial intelligence to help
famers decide when to plant, water, spray, and harvest their
crops. As climate change worsens rainstorms in the Midwest and
drought in California, the technology could also help growers
navigate more severe and volatile weather.
Katy Delaney pointed to an open patch of sediment at the base
of the canyon. A year ago, pools of cool water gleamed under
the sun and frogs basked on their banks. Now, a trickle of
water lazed through the mud. And the California red-legged
frog, whose fate had consumed eight years of Delaney’s life,
was nowhere to be seen.
Just how much Manteca’s treated wastewater is worth to
agricultural users served by the Delta Mendota Canal that are

In areas where groundwater levels have fallen because of heavy
pumping, people have often responded by drilling deeper wells.
But exactly how much that has been occurring on a nationwide
scale wasn’t clear until water experts compiled nearly 12
million well-drilling records from state and local agencies
across the country.
Gov. Gavin Newsom on Wednesday signed into law the Safe and
Affordable Drinking Water Fund bill in the tiny Fresno County
community of Tombstone Territory — where residents rely on
bottled water because their private wells are contaminated.
Starting next year, Senate Bill 200 will provide $130 million
annually to clean up drinking water in California communities
like Tombstone that lack access to safe water.
When the population collapses, like it did between 2013 to
2016, the effects ripple across the ecosystem. Brown pelicans
struggled to reproduce and those that did abandoned their
chicks. Thousands of sea lion pups were found malnourished and
dehydrated on California’s beaches. These effects may be
exacerbated by humans, especially when high fishing rates
remain when stocks are in decline. California anchovies are
almost exclusively sold abroad as food for fish farms and bait
Thoughtfully implementing state law that requires local water
users to bring groundwater use to sustainable levels within the

The state drought plans move gingerly toward encouraging
transfers of water by using clever euphemisms that avoid any
mention of water marketing. … These euphemisms are tools that
usher in a new frontier in western water law that will increase
resilience in the face of droughts, floods and forest fires
fueled by climate change.
The Trump Administration last year proposed to combine the
responsibilities of both the NMFS and the USFWS under one
federal roof. This would promote more efficient, effective, and

anadromous and freshwater fish in Western watersheds, from the
highest reaches of our headwaters to the Pacific Ocean.
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?
A new study looked at more than half a century of well depth

The Friant Water Authority is confident a parallel canal is the
best solution. This new one will be built in a way that
prepares for subsidence. A new canal would also benefit from
the Ground Water Management Act of 2014, which will regulate
how much and when water is pumped out of the ground, preventing
what some believe is the main cause of subsidence.

which are on the endangered species list.
New to this year’s slate of water
tours, our Edge of
Drought Tour Aug. 27-29 will venture into the Santa
Barbara area to learn about the challenges of limited local
surface and groundwater supplies and the solutions being
implemented to address them.
Despite Santa Barbara County’s decision to lift a drought
emergency declaration after this winter’s storms replenished
local reservoirs, the region’s hydrologic recovery often has
lagged behind much of the rest of the state.
Agricultural water suppliers must develop annual water budgets
and drought plans that meet requirements of recently enacted
legislation, and are meeting with state officials to comply
with the updated law—a process that could ultimately affect
water costs for California farmers and ranchers.
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.
Remember the parade of atmospheric-river storms that deluged
the Bay Area last winter, giving us the wettest rainy season in
20 years? There are a lot more of those on the way, scientists
say. But California will also experience more periods of
extreme dryness, according to a new study led by Scripps
Institution of Oceanography at UC San Diego.
Despite being on opposite sides of the immigration debate,
environmental groups who oppose border barriers generally
mirror cattle rancher John Ladd’s concerns about the river.
They say a wall or fence across the San Pedro could have
devastating consequences to its hydrology, as well as the
endangered species that call the river home.
If you want to dam rivers, as we were inclined across much of
the 20th century, the location of the current Parker Dam on the
Lower Colorado River makes sense – a narrow gap just downstream
from the confluence of the Colorado and Bill Williams rivers on
the Arizona-California border.
The plan is historic: It acknowledges that southwestern states
need to make deep water use reductions – including a large
share from agriculture, which uses over 70% of the supply – to
prevent Colorado River reservoirs from declining to critically
low levels. But it also has serious shortcomings. It runs for
less than a decade. And its name suggests a response to a
Industry veteran Gloria Gray took the helm at the Metropolitan
Water District of Southern California. In this interview, Gray
shares how she plans to steer the largest water supplier in the
nation through changing political priorities and climate
conditions to continue safeguarding the future of California’s
The California Water Commission held the first listening
session at its June meeting with a panel of water management
experts offering their perspectives on what a climate-resilient
water portfolio might look like.
Utilities, including several in the Bay Area, simply don’t have
the backup power to replace the electricity that Pacific Gas
and Electric Co. normally provides for water delivery and
sewage treatment. The agencies are trying to make their
operations more energy efficient and adding alternative power
sources in case the cord is cut, but it may not be enough.
A governing document called the Winterhaven Neighborhood
Standards and Landscaping Guidelines make the desired effect
clear: “Winterhaven’s dominant use of green lawns and
non-native trees creates a Midwestern environment that is
unique in Tucson …”
A new study will explore the viability of a regional pipeline
to transfer water from the Colorado River to benefit multiple
users in San Diego County and across the Southwest. The San
Diego County Water Authority’s Board of Directors approved
funds for the two-year study at its June 27 Board meeting.
A bold move by farmers to form the South San Joaquin Irrigation
District 110 years ago literally changed the economic fortunes
of Manteca, Ripon and Escalon. And no way else did SSJID have
as big as an impact as it did on Manteca.
The bill that will provide support for necessary repairs to the
Friant-Kern Canal is continuing to make forward progress in the
California legislature. Senate Bill 559 (SB-559) … was voted
through the Water, Parks, and Wildlife Committee in the
Assembly on July 2. The bill itself is seeking $400 million to
make important upgrades and repairs to the Friant-Kern Canal.
The Rosedale-Rio Bravo Water Storage District’s pilot program,
set for testing later this summer or early fall, would allow
certain landowners to buy or sell groundwater to or from
another property owner within the district.
We estimate that nearly 20%—or 840,000 acres—of irrigated
cropland in the valley has no access to surface water. … With
groundwater cuts looming and no other water supply to fall back
on, groundwater-only areas are on the front line of the effort
to bring basins into balance.
The survival of a tiny, unique desert neighborhood is
threatened because more than 60 years ago the community decided
to form a small water district instead of digging individual
wells. Borrego Air Ranch is built around a private air strip
where residents’ garages double as airplane hangers.
Pure Water Monterey, the highly touted recycled water project,
is in default on a water purchase agreement with California
American Water after failing to meet a Monday deadline for
delivering potable water even as the project’s costs rise amid
We need a broad portfolio of solutions that includes storage
above and below ground, conservation, and other options such as
traditional recycled and potable reuse to help ensure we can
better manage this vital resource when the next inevitable
drought comes along. … One part of that solution is the
proposed Sites Reservoir.
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.
On the last Saturday in June, a road in Butte County was
opened. That in itself isn’t anything unusual. Roads are opened
and closed regularly around here. But it was the significance
of this road that makes it a remarkable occurrence. It was the
road over Oroville Dam.
On June 28, farmers gathered in Los Banos to ask questions of
President Trump’s agriculture secretary, Sonny Perdue. GV Wire
took the opportunity to ask growers if they believed Trump was
doing enough to bring water to farmers. Generally, they said
they like how things are progressing.
The original treaty was implemented before the 1970 National
Environmental Policy Act, the 1973 Endangered Species Act and a
host of legal shifts that bolstered Indigenous rights… These
hallmarks of change emphasize the need to include environmental
protection and equity in an updated treaty.
In 2016 California’s rainy season kicked off right on schedule,
at the beginning of October. … By February there was so much
water filling Northern California’s rivers that Oroville Dam,
the tallest in the country, threatened to break after its
spillway and emergency spillways both failed. It was a wake-up
call. In just a few months California had gone from
five-year-drought to deluge, ending up with the second wettest
year on record for the state.
Each of the selected projects strike at the heart of the Sierra
Nevada watershed improvement program, SNC’s large-scale
restoration initiative designed to improve ecosystem and
community resilience in the region.
With a big collective sigh of relief, Californians rejoiced
that we have largely recovered from 2012-2016 drought. But this
is not a time for complacency… This should thus be a time to
develop new and better strategies for reducing impacts of
severe drought on both natural and developed systems.
Santa Barbara County’s water supply outlook has improved
significantly with a winter of strong rains, and this is
reflected in a noticeably fuller Lake Cachuma. However, the
effects of the years-long drought will take several years for
some water sources to recover…
Signs of the strong winter that the Central Sierra experienced
in 2018-19 are all around Tuolumne County two weeks into
summer, from a record tying late opening for Tioga Pass in the
High Sierra on Monday to the nearly brimful New Melones
Reservoir in the foothills.
An important blueprint for the success of farming in the
Central Valley is being developed to present to California
government officials. This blueprint outlines what must be done
to get water to the eight counties south of the delta. The
blueprint is a critical step to help keep farmers in business
due to the pressure from the Sustainable Groundwater Management
The experiment to super-energize water recharging efforts at
Fresno’s Leaky Acres appears to be working. … Tommy Esqueda,
then the director of Public Utilities, described the system to
me as “putting ‘unique’ straws in the ground. The depth and
spacing of these ‘straws’ are designed to maximize groundwater
Between 2012 and 2015, very little rain and snow fell on
California. Aquifers shrank and the land dried out. … New
research suggests the loss of deep-soil water best explains why
the mountain range’s trees were unable to withstand the drought
Oscar Meinzer (1942) credits Leonardo da Vinci (1452-1519) with
having advocated the infiltration theory slightly before
Palissy’s time, basing his theories on observations made when
he was in charge of canals in the Milan area. … Such a
scenario might explain why California DWR staff and like-minded
academics and nonprofits have all jumped on the bandwagon of
managed aquifer recharge.
The unusually wet winter (with an assist from new Colorado
River Drought Contingency Plan water reduction rules) has
substantially reduced the near-term scare-the-crap-out-of-me
risks on the Colorado River for the next few years, according
to new Bureau of Reclamation modeling.
Colorado officials are planning to build multiple large
reservoirs on the prairie northeast of Denver to capture more
of the South Platte River’s Nebraska-bound water, then pump it
back westward to booming metro suburbs struggling to wean
themselves off dwindling underground aquifers.
Greg Dion, Cal Fire’s regional urban forester for the San
Joaquin Valley, said Modesto used outdated research in
calculating the cost of buying, planting and maintaining the
5,000 trees. … Modesto also started planting trees while the
region still was in the grip of a devastating drought.
A catastrophic forest die-off in California’s Sierra Nevada
mountain range in 2015-2016 was caused by the inability of
trees to reach diminishing supplies of subsurface water
following years of severe drought and abnormally warm
From sea to shining sea may take on a new meaning in
California, as state officials are reviewing billion dollar
plans to import water from Mexico’s Sea of Cortez to help raise
water levels at the Salton Sea.
Sixty percent of California’s developed water supply originates high in the Sierra Nevada mountains. Our water supply is largely dependent on the health of our Sierra forests, which are suffering from ecosystem degradation, drought, wildfires and widespread tree mortality.
Join us as we guide you on a virtual journey into the foothills and the mountains to examine water issues that happen upstream but have dramatic impacts downstream and throughout the state.
Tribal leaders urged House lawmakers Wednesday to support a
handful of bills that would guarantee water to their tribes in
Arizona, Utah and New Mexico and fund the water treatment
plants and pipelines to deliver it.
In the long-term puzzle of ensuring that the Colorado River —
the main artery of the American West — provides water to the
millions of people in the basin who depend on it, the
challenges are mounting. Does 2019’s water stand a chance of
making a meaningful impact? Water experts say the answer is:
Sadly, not likely.
As the United States moves into the summer months, a recent
study examines whether a drought in California can be linked to
one in the Midwest. The Stanford-led study published in
Geophysical Research Letters finds that regions may fall victim
to water scarcity like dominos across the nation, the
university news service reported.
As another fire season looms, here in the small city of Grass
Valley, as in much of Gold Country where historic mining towns
nestle up to sprawling, wooded mountains, things are different
this year. What used to be a leisurely wind down to summer,
marked by high school graduations and the excitement of
vacation, has become a rush to action.
The facility would serve two main purposes. In addition to
weaning Camarillo customers off imported water from Calleguas
Municipal Water District, it would also help filter out the
everincreasing amount of salt found in the plumes of water
beneath much of the eastern half of the city.
The update reported an excellent May in terms of Colorado River
Basin run-off, yet Central Arizona Water Conservation District
board members underscored that still-half-full reservoirs point
to the need for continued conservation.
Keith Parker’s groundbreaking biology research regarding a new
subspecies of Pacific lamprey, recently published in the
science journal Molecular Ecology, may be the key to saving his
tribe’s way of life. … Parker hopes that his research will
open the door to further investigation of the lamprey, because
the future of his tribe lies with this bizarre-looking,
As the 2018-19 water year came to a close Sunday,
record-setting snowpack in the Sierras and above-average rain
means several reservoirs are near full capacity heading into
the dry summer months. Here’s a look at the past 12 months of
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
communities and further impairing already poor air quality. …
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
The polling firm FM3 Research found that a plurality of
California voters surveyed (27 percent) said climate change is
behind state wildfires. Another 17 percent of voters believe
that human error is the leading cause of wildfires, 12 percent
believe it’s forest mismanagement and 11 percent believe it’s
Enjoy the days of long, endless hot showers while you may. …
Eventually all households will be required to stay within a 55
gallon per day per resident indoor water usage for showers,
baths, laundry and dishwashing.
The Lower Basin will not drop into a Tier One shortage next
year because Lake Mead will almost certainly remain above 1,075
feet in elevation. At the same time, Mead will likely remain
under 1,090 feet. That triggers a Tier Zero shortage. “Under
Tier Zero conditions, Arizona takes a reduction of 192,000
acre-feet in its annual Colorado River entitlement,” said
Suzanne Ticknor, assistant general manager at the Central
Back in 1980, the Arizona Legislature launched urban Arizona
toward a secure water future by enacting the Groundwater
Management Act. Unfortunately, most of rural Arizona – that is,
outside the Phoenix-Tucson corridor – was largely ignored and
left to an uncertain future. That future has arrived. Water
shortages now threaten rural communities throughout the state.
Will Utah’s water supply catch up with the state’s rising
population, expected to double by 2065? It was one of the
several questions posed at Utah State University’s Research
Landscapes series focused on Utah’s waterscapes.
Senators Dianne Feinstein (D-Calif.), Cory Gardner (R-Colo.),
Martha McSally (R-Ariz.) and Kyrsten Sinema (D-Ariz.)
introduced the bipartisan Drought Resiliency and Water Supply
Infrastructure Act, a bill to improve the nation’s water supply
and drought resiliency.
Leaving more water in the Colorado River Basin could help
rivers resume their natural role. But amid this push for upper
basin residents to use less, Colorado’s booming Front Range
economy is driving cities in the opposite direction: of
manipulating rivers more by installing new dams, reservoirs and
Utah’s push to develop the $1.8 billion Lake Powell pipeline,
held up for years by political wrangling, funding feuds, reams
of red tape and massive amounts of paperwork, is now being
threatened by a tiny creature: the quagga mussel.
New research has linked production of the once-verboten plant
to a host of issues ranging from water theft and degradation of
public lands to wildlife deaths and potential ozone effects.“We
have a culture and history of cannabis cultivation in remote
areas that may be sensitive to environmental disruptions,”
explains Van Butsic, co-director of the Cannabis Research
Center at the University of California Berkeley.
Upper Colorado River Basin water users are the most vulnerable
on the Western Slope in the event of a call required by an
interstate compact to curtail use, with much of that
vulnerability resting with entities that divert water from that
basin to the Front Range, new analysis shows.
After the Freeway Complex Fire, the Yorba Linda Water District
was slapped with a lawsuit and ultimately had to pay a $69
million judgment. Even though the court determined the district
didn’t ignite the fire or act inappropriately, the district was
still held liable for fire damages because the fire
incapacitated the pumps needed to push water to the fire
hydrants in one neighborhood.
The Colorado River Drought Contingency Plan, divided into plans
for the river’s upper and lower basins, is the product of years
of interstate negotiations, business transactions and political
dealings. What, though, does it mean for Nevada and other
Western states as a whole?
Most of the seven states that get water from the Colorado River
have signed off on plans to keep the waterway from crashing
amid a prolonged drought, climate change and increased demands.
But California and Arizona have not, missing deadlines from the
The question of whether the Colorado River system is a reliable
source of water for the future was the topic of a presentation
held at the Washington County Water Conservancy District on
Thursday. … Utah is entitled to 23%, or about 1.4 million
acre feet under the compact. Utah currently uses 1 million acre
feet, Millis said. This leaves the state with 400,000 acre feet
to left to develop.
The proposed rule changes include an expansion of “categorical
exclusions.” These are often billed as tools that give land
managers the discretion to bypass full-blown environmental
studies in places where they can demonstrate there would be no
severe impacts or degradation to the land.
The states that share the river completed a drought plan
earlier this year that brings them closer to living within
currently available supplies, and a new round of negotiations
on long-term management of the river is due to begin next year.
However, a new report warns that planning for gradually
declining water supplies, as difficult as that is, may not be
enough to adequately prepare for the future.
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,
and we in the California almond community are all rooting for
the governor, his fellow policymakers and regulators to succeed
in finding viable solutions and common ground.
First adopted in 2013 amid drying wells over the basin, the
county offset ordinance put a theoretical moratorium on
agricultural pumping. But the policy is set to expire later
this year when North County leaders adopt a basin-wide
sustainability plan—even though that plan could take another
several years to fully take effect.
California regulators have approved allowing utilities to cut
off electricity to possibly hundreds of thousands of customers
to avoid catastrophic wildfires like the one sparked by power
lines last year that killed 85 people and largely destroyed the
city of Paradise.
In my 40 years at the California Department of Water Resources,
I have seen changes in climate that have convinced me that the
full picture is changing and our extrapolation methods are
losing value rapidly. This is especially true in extreme years,
wet or dry – such as 2015, when the statistics are just not
going to be accurate enough to meet our growing water
Earlier this month the governor’s Drought Interagency
Coordinating Group unanimously voted to inform the governor
that Arizona’s long-running drought declaration should
continue. This means Arizona has been in a state of drought for
more than 20 years, surpassing the worst drought in more than
110 years of record keeping. Now that our drought has been
extended yet again, it leaves many to wonder what it will take
to get us out of this drought.
The study, published in the journal Ecological
Applications, found that thinning and prescribed fire
treatments reduced the number of trees that died during the
bark beetle epidemic and drought that killed more than 129
million trees across the Sierra Nevada between 2012-2016.
The largest water agency in Silicon Valley has been secretly
negotiating to purchase a sprawling cattle ranch in Merced
County that sits atop billions of gallons of groundwater, a
move that could create a promising new water source — or spark

Despite years of scientific research pointing to prescribed or
“controlled” burns as a successful method of clearing brush and
restoring ecosystems, intentional fire-setting by federal
agencies has declined in much of the West over the last 20
years, the study found. “This suggests that the best available
