Trump started promising more water to Central Valley growers
before he was elected. During a campaign stop in Fresno three
years ago, he dismissed the drought, then in its fifth year, as
a hoax and snorted at legal protections for endangered fish in
the Sacramento-San Joaquin Delta.
In 2014 California introduced the Sustainable Groundwater
Management Act (SGMA) into state law to help manage the
conflict between ground and surface water. But updating legal
structures to accommodate evolving scientific knowledge
involves far more than simply rewriting statutes, according to
researchers in the US.
The Forest Resilience Bond uses private capital to finance
forest restoration activities. Beneficiaries, including the
U.S. Forest Service and the California Department of Forestry
and Fire Protection, reimburse investors over time. Yuba Water
has pledged $1.5 million toward the project and the state of
California has committed $2.6 million in grant funding, with
additional funding from the Sierra Nevada Conservancy.
Aquatic animals in regions like California that have
historically experienced frequent droughts have evolved
remarkable adaptations to dealing with dry conditions. However,
the duration, severity, and frequency of droughts are all

Before electric refrigeration brought cheap and available ice
in the early 20th century, ice was harvested along Truckee’s
lakes and rivers. Truckee’s cold mountain air and readily
available clear streams created an ideal environment for ice
companies to create and harvest ice.
A couple of weeks ago, I wrote an article in which I — perhaps
cavalierly — described Los Angeles as a desert. … There was a

I also heard that it isn’t?
The majestic beauty of the Sierra
Nevada forest is awe-inspiring, but beneath the dazzling blue
sky, there is a problem: A century of fire suppression and
logging practices have left trees too close together. Millions of
trees have died, stricken by drought and beetle infestation.
Combined with a forest floor cluttered with dry brush and debris,
it’s a wildfire waiting to happen.
Fires devastate the Sierra watersheds upon which millions of

Federal scientists pulled no punches in their report: The Trump
administration’s plan to send more water to San Joaquin Valley
farmers would force critically endangered California salmon
even closer to extinction, and starve a struggling population
of West Coast killer whales.
The July 1 assessment, obtained by The Times, outlines how
proposed changes in government water operations would harm
several species protected by the Endangered Species Act,
including perilously low populations of winter-run salmon, as
well as steelhead trout and killer whales, which feed on
One of the key factors when assessing fire danger is the
moistness of the vegetation. When it was raining all the time,
plants were soaking up a lot of that water, which helped them
produce new growth and keep their limbs well hydrated. Usually
by August, they’ve dried out to dangerously low levels, but
this year they’re holding on a bit longer, in part due to
cooler summer temperatures.
The plan affecting Sacramento River tributaries has not been

to take water cutbacks.
For a moment as columns of sunlight drifted through the pines
with the cobalt surface of Lake Tahoe in the background, it
seemed as though the partisan rancor so characteristic of this
political moment might temporarily evaporate. But such
congeniality was short lived, if it ever lived at all.
Solar energy projects could replace some of the jobs and tax
revenues that may be lost as constrained water supplies force
California’s agriculture industry to scale back. However, the
shift from farm to solar is controversial — it can alter the
pastoral landscape and take some of the most fertile soil in
the world out of production at a time when the global
population is soaring.
California’s rivers and streams have experienced enormous
changes over the past 150 years, and a warming climate brings

city’s maintenance of its water sources.
Hydrogen sulfide is associated with the natural processes
occurring in the Salton Sea, a non-draining body of water with
no ability to cleanse itself. Trapped in its waters are salt
and selenium-laden agricultural runoff from surrounding farms,
as well as heavy metals and bacterial pollution that flow in
from Mexico’s New River, authorities said.
The Lake Powell Pipeline (LPP) proposal arose from a belief
that Utah has an unused share of the Colorado River and a fear
of water shortages stifling Washington County’s rapid

Irvine Lake looks a lot different today than it did a year ago.
Last September the reservoir looked like a giant puddle at 13
percent of capacity, today, after a rainy winter, the water

shoreline fishing on Aug. 17.
Not every bloom is toxic, but the toxins produced by the
blue-green algae can be harmful and even deadly for pets when
they eat the algae or drink the water, even in small amounts,
water experts warn. Summer heat, stagnant or slow-moving water
and nutrients from agricultural or septic runoff are an ideal
recipe for the toxic stew.
In a region that has already seen two 20-year droughts, the San
Bernardino Valley Municipal Water District continues to invest
in water supplies to help the region sustain prolonged

Although prescribed burns have been part of federal fire policy
since 1995, last year the Forest Service performed them on just
one per cent—some sixty thousand acres—of its land in the

Desalination began to lose its urgency among Californians and
their public officials two years ago, after the drought-busting
winter of 2016-17, when heavy rain and snow ended dry
conditions in most of the state. The idea of drawing potable
water from the sea became even less of a priority this year,
when an autumn of record-level fires gave way to one of the
state’s wettest winters on record.
With the last drought in the rearview and the next one

Californians, your yard sprinklers are about to get a little
bit more expensive. The good news is, your water bill is about
to get cheaper. California on Wednesday officially adopted new

gallons of water per day within 10 years, enough to supply San
Diego, the second largest city in the state.
Nowadays there’s about a 7 percent chance that snowy areas in
the western U.S. will get two really bad snow years in a
row—years with snowpack lower than a quarter of the long-term

apace, those bookending “snow droughts” could occur about 40
percent of the time, according to work published in August in
Geophysical Research Letters.

So, how much is 50 gallons per day?
The proposed changes to Clean Water Act permitting rules,
announced Friday by the U.S. Environmental Protection Agency,

The Delta smelt is practically extinct in the wild already. So
could the Delta be repopulated by taking up the farmers’ offer
to “hatch and repopulate the fish,” as Jack Fowler says in

Except that the Delta smelt war has never really been about the
Delta smelt at all.
Many farmers probably haven’t read the new report from the
United Nations warning of threats to the global food supply
from climate change and land misuse. But we don’t need to read
the science — we’re living it. Here in the San Joaquin Valley,
one of the world’s most productive agricultural regions,
there’s not much debate anymore that the climate is changing.
Other than talking of a “planned retreat” from the water and
bluffs, local government has a hard time getting its head
around this crisis. Like so many of our regional problems —
traffic, homelessness, housing — each government unit feels
somewhat powerless on its own. And with no accountability, the
real work is negligible. Meanwhile, California crumbles.
What would happen if we ran out of water? For an increasing
number of people, that question is moving from a hypothetical

In a newly published study, my colleagues and I analyze
year-to-year variations of future snowpack to see how
frequently western states can expect multiple years in a row of

While other regions grappled with destructive waves and rising
seas, the West Coast for decades was spared by a rare
confluence of favorable winds and cooler water. This “sea level
rise suppression,” as scientists call it, went largely
undetected. Blinded from the consequences of a warming planet,
Californians kept building right to the water’s edge. But lines
in the sand are meant to shift.
California’s Secretary of Environmental Protection Jared

of storage had not been achieved since the late 1940s.
The general rule of thumb had been that El Niño years — when
the sea surface in a region off the coast of Peru is at least 1
degree Celsius warmer than average — tend to have more
rainfall, and La Niña years, when that region is 1 degree
Celsius cooler than average, tend to have less rain. But that
simple rule of thumb doesn’t always hold true.
They call it “managed retreat.” More than a buzzphrase, the

high” pressures on its water availability. The state’s score is
on par with the United Arab Emirates in the Middle East and
Eritrea in Africa, the World Resources Institute (WRI) found.
California ranks second, followed by Arizona, Colorado and
Hiding and waiting is a great strategy as long as droughts are
temporary. But as our climate becomes warmer, increased
evaporation will make it effectively ever drier, and rainfall
will arrive ever less predictably at the right time of year.
Native plants will thus face long-term increases in water
stress, often exacerbated by intensified fire and shifts in
their delicate coexistence with exotic species.
A Butte County project will expand its partnership with Chico
State and Stanford University to analyze available groundwater
systems. … It’s a groundbreaking project for water management
in the county, according to Paul Gosselin, director of the
county’s water and resource management department.
One year from its initiation of the design-build process for
the Sterling Natural Resource Center water recycling plant,

the project’s considerable progress and adopted a few
modifications during a July 24 meeting. … The project will
construct a wastewater recycling plant capable of treating up
to 10 million gallons per day.
Klamath River Renewal Corporation announced last week the
selection of Resource Environmental Solutions, LLC to perform
restoration work after the proposed removal of four Klamath
dams, and on Monday, KRRC announced it had filed with Federal
Energy Regulatory Commission the answers to a plethora of
questions brought forward by a Board of Consultants in December
If we stand by and do nothing, California’s transportation
network will be disrupted, its economy will be jeopardized as
tech, manufacturing, tourism and ag industries falter, sandy
beaches lost, and coastal residents will be forced to relocate,
putting a strain on resources in inland communities. Yet many
Californians have been treating sea level rise as a distant
A Butte County project will expand its partnership with Chico
State and Stanford University to analyze available groundwater
systems. The project involves analysis of well logs, and hopes
to expand the analysis using magnetics and a grid to fill in
holes in the data.
New regulations from the California Public Utilities Commission
have authorized energy companies like PG&E to turn off
power to avoid or reduce the risk of wildfires… For
commercial customers — like other utility companies — it could
mean huge losses in business and potential financial
repercussions for their customers. The California Water Service
is already preparing to take that hit this summer.
Water resource management is key in Ventura County to help
address the perils local residents face from global warming,
such as flooding, drought and sea level rise. The preliminary
draft of the 2040 General Plan update on Water Resources
Element is so much more than an “update.”
Two of the most basic questions about biodiversity are “what is
it?”, which is the focus of taxonomists, and “where is it?”,
which is the realm of biogeographers. Understanding basic
patterns in the biogeography of an urban area is the focus of a
partnership between The Nature Conservancy and the Natural
History Museum of Los Angeles County. We call our project
Biodiversity Analysis in Los Angeles (BAILA).
Opponents of the twin tunnels breathed a collective sigh of
relief in April when Gov. Gavin Newsom put a formal end to the
California WaterFix project, but that action also called for
the assessment of a single-tunnel project in the Delta. The
first major step in that direction took place last week when
the Department of Water Resources (DWR) initiated a series of
negotiations with public water agencies that participate in the
State Water Project (SWP)…
The California Coastal Commission has encouraged cities to
include a strategy called “managed retreat” in plans to prepare
for sea level rise. But the commission may be retreating from
that position. Del Mar is a prime example of a city where an
entire neighborhood is threatened by rising seas.
A new federal management plan for the Klamath River is proving
to be a disaster for salmon, a lawsuit alleges. The Yurok Tribe
and the Pacific Coast Federation of Fishermen’s Associations
filed a lawsuit against the Bureau of Reclamation and the
National Marine Fisheries Service on Wednesday because the new
plan has led to drought-level flows in the lower Klamath River
and an increase in salmon with a potentially lethal parasite…
One hundred and fifty years ago, a group of explorers led by
Civil War veteran John Wesley Powell set out to document the
canyons of the Green and Colorado Rivers. It was the first trip
of its kind. To commemorate the journey, a group of scientists,
artists and graduate students from the University of Wyoming
called the Sesquicentennial Colorado River Exploring Expedition
has been retracing his steps this summer.
A flexible, reliable water supply is essential to California’s
economy and to the job creation and job security goals of
California’s working families. … Of all the projects vying
for California’s attention, the proposed Sites Reservoir in
Northern California offers the most tangible benefits.
Lake Tahoe, with its iconic blue waters straddling the borders
of Nevada and California, continues to face a litany of threats
related to climate change. But a promising new project to
remove tiny, invasive shrimp could be a big step toward
climate-proofing its famed lake clarity.
California Sen. Dianne Feinstein has joined with a Montana
Republican to craft a bill that would expedite logging and
other forest management projects near electrical transmission
lines and roads in an effort to head off catastrophic
wildfires. The bill is also aimed at slowing or stopping
lawsuits that block logging projects on federal land.

A San Luis Obispo County policy regulating pumping from the
Paso Robles Groundwater Basin has hamstrung how Robert
Galbraith can farm his land. For decades, the family grew corn
silage, Sudan grass, alfalfa, and grains on their few hundred
acres. Now, Galbraith has essentially lost the right to farm,
though he can see many a green vineyard down the road.
Water is indeed the most precious natural resource in the arid
West and from that perspective it should come as no surprise
that water-rights issues on Lake Tahoe and Truckee River have
been at the center of negotiation and controversy since
pioneers first settled the region.
A bill signed Wednesday evening by Gov. Gavin Newsom will
require Cadiz Inc.’s Mojave Desert groundwater pumping
project to undergo further review to show it will not harm
the surrounding environment. … It requires the State Lands
Commission to determine that projects involving the transfer of
water from a groundwater basin won’t adversely impact the

Topanga State Park, and both state and city authorities have
launched investigations into DWP’s actions, part of a wildfire
prevention project aimed at replacing wooden power poles with
Like many communities throughout California, Carpinteria faces
sustained and historic drought conditions. … 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 to be used for various needs,
including potable drinking water.
The Westlands Water District, which provides irrigation water
to farmers on the west side of the San Joaquin Valley, was
working on a report assessing the environmental impacts of
raising the height of the dam. But a judge ruled Wednesday that
Westlands’ work violated a state law that prohibited local and
state agencies from participating in any projects that would
have an adverse impact on the McCloud River.
California American Water is seeking to raise its Monterey area
average customers’ bills by nearly 18 percent over a three-year
period from 2021-2023. … Under the proposal, the “average”
Cal Am customer would see their monthly rates increase from
about $89.40 to $105.42 over the three-year period.
The San Diego County Water Authority’s Board of Directors last
week approved a contract to study the viability of a new
regional water conveyance system that would deliver water from
the Colorado River to San Diego County and provide multiple
benefits across the Southwest. The $1.9 million contract was
awarded to Black & Veatch Corporation for a two-phase study.
Native seaweed has the potential to be cultivated in California
coastal waters and used to alleviate the effects of local ocean
acidification, according to a new study funded by NOAA’s
California Sea Grant.
California’s biggest river—the Sacramento—needs a lot of room
to spread in big water years. A floodplain project called the
Yolo Bypass allows it to flood naturally, while also providing
habitat for waterbirds, fish, and other aquatic species. We
talked to Ted Sommer, lead scientist for the Department of
Water Resources (DWR), about this versatile landscape.

The Groundwater Sustainability Agency board will submit a
sustainability plan to the Department of Water Resources in
2021 and begin to implement that plan in 2022-2024. The board
last week heard a presentation about funding options to pay for
the groundwater management plan — including fees, taxes or
assessments to customers — and specific projects to implement
The silvery panels looked like an interloper amid a patchwork
landscape of lush almond groves, barren brown dirt and saltbush
scrub, framed by the blue-green strip of the California
Aqueduct bringing water from the north. … Solar energy
projects could replace some of the jobs and tax revenues that
may be lost as constrained water supplies force California’s
agriculture industry to scale back.
While it may not be obvious to some, sustainable groundwater
management is inherently connected to the long-term survival of
the Delta. Not only does the state’s most significant
groundwater use occur in regions that also rely upon water from
the Delta watershed, reduced reliance on the Delta and improved
regional self-reliance are central to many of the goals
outlined in the Delta Stewardship Council’s Delta Plan.
It is seen as a major move from one of the world’s biggest
credit ratings agencies that could have a significant impact on
how seriously climate risk factors are viewed by financiers.
Based in California, Four Twenty Seven scores physical risks
associated with climate-related factors and other environmental
issues, including heat stress, water stress, extreme
precipitation, hurricanes and typhoons, and sea-level rise.
The heavy rains that hit the Central Coast this past winter are
keeping recreators at area lakes and reservoirs happy this
summer. However, the precipitation has done little to ease
concerns for a group fighting Monterey County over the water it
withdraws from Lake Nacimiento.
County and tribal officials are reporting that new testing at
sites around Clear Lake have revealed half a dozen areas with
cyanobacteria levels that trigger health warnings. Water
monitoring is regularly done by the Big Valley Band of Pomo

Californians are worried about global warming causing severe
wildfires and consider the health of beaches and the ocean key
priorities, according to a new statewide survey focused on the
environment. … While the poll found significant concern about
rising seas and more extreme heat, it was at a lower level than
the preoccupation with wildfires.
John Reager is being honored for his work on the GRACE mission,
studying Earth’s water cycle by measuring groundwater, floods
and drought. This helps him and his colleagues study how
extremes of water vary with time and climate change.
Seven and a half years after it was formed, the Monterey
Peninsula Regional Water Authority is moving forward with a
smaller, less expensive version of itself. … The authority
has completed the vast majority of its mandate in backing a new
water supply for the Peninsula and can now be expected to shift
its focus toward dealing with the state water board’s Carmel
River pumping cutback order.
On Monday, the state of California and a coalition of fishing
groups and environmentalists asked a judge to bar Westlands
from completing a crucial environmental report in hopes of
stalling the project. “Everything we see looks to be illegal,”
said deputy attorney general Russell Hildreth. At issue is a
stretch of the McCloud River that both sides agree would be
inundated by the project.
California has grown from 10 million to at least 40 million
since 1950, making it necessary to move water over long
distances to where people live and work. Close to two thirds of
the state’s population is bunched in a few water-dependent
More than 61,000 acre-feet of snowmelt and rainfall has been
diverted from Mill Creek and the Santa Ana River by the
District and recharged into the groundwater basin for future
use by those who pump water from the basin. Imported water was
also used to help supplement the amount of water stored.
What happens when the farmer’s source of water is tapped out?
They look for it elsewhere. This could become a major problem
as their adaptation to climate change only exacerbates another
major impact from climate change—water scarcity.
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.
Water is key to everything in California. If you have control
of water in sufficient amounts you control your destiny. There
are three things on the horizon that city leaders had best pay
heed before they buy into the PG&E model regarding critical
and essential utilities and go for the money in the here and
now while ignoring long term consequences.
To reduce flooding on roads near Novato Creek, a Marin County
flood control agency and a local environmental group are
partnering to upgrade flood control equipment and improve
wetlands in the Simmons Slough basin.
The center, being built at North Natomas Regional Park, will

course and play area…
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.
Pacific salmon that spawn in Western streams and rivers have
been struggling for decades to survive water diversions, dams
and logging. Now, global warming is pushing four important
populations in California, Oregon and Idaho toward extinction,
federal scientists warn in a new study.

progressing locally from Gary Serrato, executive director of
the North Kings Groundwater Sustainability Agency, Christina
Beckstead, executive director of Madera County Farm Bureau, and
David Orth with New Current Water and Land.
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.
The Sacramento-San Joaquin Delta is arguably the most
extensively studied and monitored ecosystem in the world. This
has generated mountains of data on everything from the
locations of the smallest fish to the water quality conditions
of the largest reservoir. Knowing where to access the most
up-to-date information can be a real challenge, but fortunately
several online dashboards can help
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.
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.
New measurements taken in California’s Monterey Bay show that
it absorbs carbon dioxide emissions from the surrounding cities
and agricultural lands, making it more acidic. The finding is
reminiscent of the urban heat island effect, in which cities

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…
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.
