Climate change involves natural and man-made changes to weather
patterns that occur over millions of years or over decades.
In the past 150 years, human industrial activity has accelerated
the rate of change in the climate due to the increase in
greenhouse gases (carbon dioxide, methane, and nitrous oxide).
Scientific studies describing this climate change continue to be
produced and its expected impacts continue to be assessed.
In California, the California Environmental Protection Agency has
found temperatures have risen by about 1.5 degrees since 1895.
Looking ahead, temperatures could rise by 2.7 degrees and its sea
levels by 55 inches in the next 40 years, according to the
California Energy Commission and the California Natural Resources
Agency. These are among the ongoing issues the state faces as it
grapples with climate change.
Already, California is confronting rising demand for water and
diminishing supplies. At the same time, the state’s water
infrastructure such as levees is increasingly aging and in
disrepair—conditions expected to be made worse by climate change.
They call it “managed retreat.” More than a buzzphrase, the
term has become something of a movement among officials looking
for ways to cope with rising sea levels and increased river
flooding. But what about in fire country, where California has
seen so much devastation in recent years?
For five years or so, German-born, San Francisco-based
photographer Thomas Heinser has made a study of the state’s
scarred landscapes. His images, shot from the open side of a
helicopter, focus on the after-effects of drought, wildfire,
and human profit.
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

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 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.

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

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.

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

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.
John Reager is being honored for his work on the GRACE mission,

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

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

of some species that were in their larval stages when the Blob
hit its crescendo.
California Landscape Contractors Association’s Sandra Giarde
… points out that parts of California are already teetering
back on the edge of a drought again. Laws have yet to change
that were put into place to conserve water during the drought,
such as rules against hosing down concrete sidewalks. Those
bans will only slowly be lifted by each municipality over time,
if they’re even lifted at all.
Winter-run Chinook’s need for cool temperatures has meant
recent catastrophic losses when temperatures got too high, but
a few recent studies have altered our understanding of this
species’ temperature tolerance. This new knowledge may allow
water managers to actually release less cold water overall,
while still improving winter-run survival.
For around 20 years, Los Angeles has shipped a large portion of
“biosolids” from its toilets to fertilize a farm it owns just
west of Bakersfield. Bakersfield, in return, has been providing
an annual load of 18,000 acre-feet of free water to the farm.
However, after passage of the Sustainable Groundwater
Management Act, the value of treated wastewater increased.
While California contemplates new dams for its thirsty future,
it’s also thinking about taking out old ones. Along with
advancing plans to demolish three dams atop the Klamath River,
there’s a movement to rethink and possibly take out a water and
power dam in the Mendocino County back country.
District Fire Chief Todd McNeal, who proposed the project, said
the draft point will allow firefighters to pull raw water from
the reservoir during an emergency and take pressure off the
Scientists at UC Davis have developed five new types of the
berry set to hit the market this fall. … Researchers say
these new strawberries are the best of both worlds: the
strawberries will use less water, fertilizer and pesticides and
still produce more, healthier, higher-quality strawberries.
State Department of Water Resources officials emphasized they
aren’t claiming well water use is harming the subterranean
reservoir beneath the Napa Valley floor. Rather, they said a
more than 1,000-page basin report submitted by Napa County
doesn’t allow them to make a judgement.
One evening, at a community center in the Sacramento Valley, a
teacher, a civil engineer, a tomato farmer and a local
foundation board member found themselves standing above a
table, feverishly competing to scoop the most glass beads from
a large, communal bowl. But there was a catch.
Residents of a small Southern California desert community hit
hard by this month’s big earthquakes no longer need to boil tap
water. San Bernardino County authorities announced Wednesday
the boil-water notice for Trona and neighboring areas has been
lifted and citizens do not need to rely on bottled water.
Los Angeles Mayor Eric Garcetti Tuesday nominated a longtime
water-resources expert for a seat on the Metropolitan Water
District Board of Directors. Tracy Quinn serves as the
California director of water efficiency for the Natural
Resources Defense Council and has almost two decades of water
Water hidden beneath the earth’s surface comprises 98% of the
planet’s fresh water. On average, this groundwater provides a
third of all total water consumed… Before we even start to
improve groundwater management, we must better understand and
measure it, says international groundwater expert Craig
Simmons, from Flinders University in Adelaide.
A coalition of 55 environmental, fishing, and water policy
groups has written Gov. Gavin Newsom, backing his Water
Portfolio planning process, and announcing that they plan to
take an active part with their own proposals for the plan.
Many Delta problems are worsening. Climate change is raising
sea levels and temperatures, making floods and droughts more
extreme and will likely further alter the mix of species. State
legislation to end overdrafting of groundwater will increase
demands for water from the Delta from farmers in the San
Joaquin Valley struggling (mostly in vain) to find replacement
Secretary of Natural Resources Wade Crowfoot discussed the
Governor’s water resilience portfolio and reiterated the Newsom
administration’s support for modernized conveyance in the
Delta. That was followed by a robust discussion that included
Delta conveyance, water storage, emerging contaminants and
PFAS, among other things.
Following extensive technical review, DWR approved seven
existing groundwater management plans and two 10-year
sustainable yield analyses as alternatives under SGMA. One
existing groundwater management plan and five 10-year
sustainable yield analyses were not recommended for approval as
Federal biologists worked frantically this year to meet a
deadline to assess the environmental impacts of Trump
administration plans to send more water to Central Valley
farmers. But the biologists’ conclusion — that increased
deliveries would harm endangered Chinook salmon and other
imperiled fish — would foil those plans.
If PG&E shuts down power as part of its plan to prevent
fires in northern California, the water will keep flowing in
the Valley, thanks to Zone 7 Water Agency’s preparations. …
Zone 7 has two plants for water treatment and distribution …
Both have backup generators in case power stops. Each has
a three-day supply of fuel, but the agency also has contracts
with other generator suppliers who can each roll out at least
three days of juice.
The Desert Water Agency board voted 5-0 on Tuesday to move from
at-large to elections by division, or district, beginning in
November 2020. The move comes nearly eight months after a
Mailbu law firm asked the agency to switch in order to comply
with the California Voting Rights Act.
The rebate for Malibu residents who remove grass landscaping
has been increased from $4 to $5 per square foot of turf
removed, the City of Malibu announced Monday. The incentive is
part of the Malibu Smart water conservation program offered by
the City of Malibu, County of Los Angeles and West Basin
Municipal Water District.
If PG&E has to shut off power in the East Bay to prevent
wildfires from igniting and burning homes, residents will be
strongly urged to severely reduce their water use during the
emergency. That’s because their main water supplier, the East
Bay Municipal Utility District, may have its power cut off,
too, and be forced to rely on 29 emergency backup generators.
River towns can start by restricting floodplain development so
that people and property will not be in harm’s way. This will
create space for rivers to spill over in flood season, reducing
risks downstream. Proposals to raise and improve levees should
be required to take climate change and related flooding risks
Groundwater overdraft is a major problem globally and has been
a persistent and growing problem in California for decades.
This overdraft is predominantly driven by the economic value of
water for agricultural production and cities.
Agricultural scientists across the globe including at Stanford
University and the University of California at Davis have in
recent years been making new discoveries showing that healthy
soil holds more carbon than previously thought and that good
soil management can serve as an important carbon sink.
Update 2018 presents a vision for greater collaboration and
alignment among water sectors and institutions, sound
strategies, and long-term investments needed for the
sustainable management of the California’s water supply.
Initially, farmers had been contracted $285 per acre/feet for
conserved water and the IID welcomed all participants. However,
due to the farmers’ innovation and ingenuity, the total
acre/feet saved the past three years exceeded the amount needed
for the QSA transfer.
The Eel River—once home to the state’s third-largest salmon and
steelhead runs, all of which are now listed as threatened―may
see the return of healthy fisheries in coming years. A unique
opportunity to remove a dam that blocks fish from reaching
spawning habitat has arisen. We talked to Curtis Knight,
executive director of CalTrout, about the situation.
The Bureau of Reclamation announced that 30 projects will
receive $5.1 million from the Desalination and Water
Purification Research Program to develop improved and
inexpensive ways to desalinate and treat impaired water.
Brokered in large part by rookie state senator for California’s
14 Senate District, Melissa Hurtado, the southern portion of
the Valley has gained tens of millions of dollars of investment
in drinking water, asthma mitigation, aging and disability
resource centers and Valley Fever research.
The Clovis City Council has approved landmark water deals with
the Fresno Irrigation District that officials say will secure
the city’s growth for decades to come. According to the Clovis
General Plan, the city expects 280,000 residents in 2083 — 2.5
times its 110,000 population. Plans call for Clovis to grow
northeast and southeast.
Monterey County supervisors voted Monday to let California
American Water start construction on its desalination plant
even before the state Coastal Commission makes a decision on
the technology involved.
New research shows that the extreme weather and fires of recent
years, similar to the flooding that has struck Louisiana and
the Midwest, may be making Americans sick in ways researchers
are only beginning to understand.
Summers in San Francisco may soon feel more like the warmer
East Bay. The East Bay may soon feel more like Sacramento. And
Sacramento — well, it might just be too hot to stick around any
longer. One of the most detailed studies on rising temperatures
suggests that few places in the United States will be
unaffected by extreme heat by the middle of this century.
Keystone projects for the midcounty planning effort, mandated
by the state for all groundwater-dependent agencies, include
stormwater runoff management, Soquel Creek Water District’s
Pure Water Soquel advanced water treatment plant, and the city
of Santa Cruz’s ongoing efforts to develop a supplemental water
supply that would primarily make use of unused winter river
runoff, likely through new storage options.
Tashiana Osborne is a PhD student with the Scripps Institution
for Oceanography at UC San Diego where she works within the
Center for Western Weather and Water Extremes on atmospheric
river research: As a graduate student, you already have an
incredible amount of experience, including working as a storm
chaser and intern at NASA. Can you tell us a little more about
your current research?
For years, the people of the Northern San Joaquin Valley have
been trying to get hydropower recognized for what it is: the
original source of clean electricity. Our efforts have been
stymied by people who feel entitled to decide what is, or
isn’t, green enough. That’s why I have begun the process of
modifying our state Constitution to recognize safe, abundant,
carbon-free hydropower as a reliable source of renewable energy
in our fight against climate change.
Californians may feel like they’re enduring an epidemic of
fire. The past decade has seen half of the state’s 10 largest
wildfires and seven of its 10 most destructive fires, including
last year’s Camp Fire, the state’s deadliest wildfire ever. A
new study, published this week in the journal Earth’s Future,
finds that the state’s fire outbreak is real—and that it’s
being driven by climate change.
Larry N. Olinger, the tribal council vice chairman and a former
chairman of the Agua Caliente Band of Cahuilla Indians, died
Monday morning, the tribe said. He was 80 and lived in Palm
Springs. … While on the tribal council, Olinger worked to
resolve a longstanding dispute between the tribe and the
Coachella Valley Water District and the Desert Water Agency.
In black and white, John Trotter documents the use of water

They’ll use less water, less fertilizer and fewer pesticides –
and they will probably be cheaper. The Public Strawberry
Breeding Program at UC Davis just announced five new strawberry
varieties that will be on the market in the fall and are
expected to benefit farmers, sellers and consumers alike.
Fish die-offs in freshwater lakes are an increasing threat in
California, and experts say climate change is to blame. … In
a 2014-2017 report, the California Department of Fish and
Wildlife found that high summer temperatures were not only
worsening the quality of the water, but drying out freshwater
bodies that hosted endangered species.
Just days before federal biologists were set to release new
rules governing the future of endangered salmon and drinking
water for two-thirds of Californians, the administration
replaced them with an almost entirely new group … to “refine”
and “improve” the rules, according to an email obtained by
KQED. Environmental groups said the Department of
Interior is interfering with the science…
Between 1890 and 1910, almost 90% of Humboldt Bay’s salt
marshes, about 8,100 acres, were diked and drained for
agricultural uses or walled off from tidal inundation with the
construction of the Northwest Pacific Railroad. Now … the
earthen dikes are beginning to fail, both because they haven’t
been maintained and because they aren’t tall enough to hold
back the rising tides brought on by rising sea levels.
Colorado was the last Western state to legalize greywater usage
in 2013. Officials say that by 2050, our water supply could
fall short for over one million people. … Colorado’s Water
Plan wants to close the gap and recognizes greywater as one
tool to help make that happen. However, not a single
state-approved greywater system has been built since it was
Benthic macroinvertebrates, including insect larvae, worms,
snails, and other backbone-lacking creatures, often rule the
alpine waterways. However, their high-altitude homes put them
on the front lines of climate change, which threatens to have
major impacts on mountain streams. This is particularly true of
streams in the Sierra Nevada of California…
In the 1990s, he played a central role in some of the country’s
biggest environmental decisions. … He could have chosen to
wrap up his career when he left office at the end of the
Clinton administration in 2001. But Babbitt has
remained actively engaged in issues he cares about.
Only 15 out of the thousands of desalination plants operating
today worldwide are powered by nuclear. A small one is at the
Diablo Canyon Nuclear Plant in California, slated to be closed
soon. The plant could power several huge desalination plants
for decades that could desalinate its own cooling water,
removing the most commonly stated problem with the plant.
The Kern County Public Health Services Department recently
received water samples from eight different locations in Lake
Isabella, and two water samples indicated the presence of
blue-green algae, or cyanobacteria, at a cautionary level. This
type of algae can be considered potentially harmful.
A longtime court case involving the shutoff of water to
multiple water users in the Klamath Basin in 2001 attracted
wide-ranging attention from Pacific Northwest-based
organizations and those within the legal community in
Washington, D.C. Nearly 90 minutes of oral arguments were heard
Monday at the U.S. Court of Appeals at the Federal Circuit.
Proponents have said SB 1 will keep Trump from delivering more
water to farms, thereby harming endangered fish. That sentiment
is exactly what makes SB 1 so dangerous. It relies on the
worn-out trope that California’s water issues boil down to
“farms versus fish.”
Climate-conscious local and state officials are increasingly
embracing electricity sources that float on water, as they seek
ways to convert their least-coveted spaces into hubs of
electricity. This summer alone, developers broke ground on
California’s largest floating solar project, located on a
wastewater treatment pond in Sonoma County.
If we can make things just a bit easier and provide reliable
water and habitat, salmon in California can and will recover.
This understanding informed the State Water Resources Control
Board’s recent approval of a legally-required water management
plan to reverse the ecological crisis that threatens an
important coastal industry, drinking water for millions, and
the natural heritage of California.
Seeking to implement updated scientific methods to its
operations in the Golden State, the Bureau of Reclamation
released a draft environmental impact report on the coordinated
operations between the federal Central Valley Project and
California’s State Water Project on Thursday.
A bill sponsored by U.S. Sens. Martha McSally and Kyrsten
Sinema would put aside hundreds of millions of dollars for
water storage projects, water recycling, and desalination
plants. … The bill is also sponsored by California Democratic
Sen. Dianne Feinstein, and Colorado Republican Senator Cory
A project to pump billions of gallons of water out from under
the Mojave Desert and sell it to people in Southern California
could be slowed by a bill approved for the first time on
Thursday by the Democratic-controlled Legislature.
The drought may be over, but Arcadia residents and businesses
must restrict their irrigation and water consumption yet again
this summer as the city’s mandatory water conservation program
continues to push through its first of eight phases.
Government scientists predict 40 places in the U.S. will
experience higher than normal rates of so-called sunny day
flooding this year because of rising sea levels and an abnormal
El Nino weather system. A report released Wednesday by the
National Oceanic and Atmospheric Administration predicts that
sunny day flooding, also known as tidal flooding, will continue
A new study, just published in Nature Geoscience, reveals an
elegant formula to explain why some trees died and others
didn’t — and it suggests more suffering is in store for forests
as the climate heats up.
To better understand groundwater markets, attendees at the
meeting played a groundwater market game, which was developed
by the Environmental Defense Fund and the University of
Michigan to teach players about the challenges of managing
scarce groundwater resources.
There’s a new twist in the California-Trump brawl in the state
Legislature. It’s aimed at overriding the president’s power to
weaken environmental protections. Put simply, any federal
protections President Trump tried to gut would immediately
become state regulations in their original, strong form.
An irrigation district may adopt and enforce reasonable rules
related to water service, and may terminate water delivery for
failure to comply with such rules, a California appellate court
ruled. Although this case involved an irrigation district, the
decision may also strengthen other water providers’ authority
to adopt and enforce rules relating to water service.
Rain – and plenty of it – was the big weather story in June,
adding to a record-breaking 12 months of precipitation for the
contiguous U.S. It’s the third consecutive time in 2019 (April,
May and June) the past 12-month precipitation record has hit an
The $650 million project involves a joint financial partnership
between Padre Dam, Helix, San Diego County and the city of El
Cajon. The Helix board voted 4-1 last week to continue funding
the Advanced Water Purification project, which is expected to
have reclaimed water flowing into faucets by 2025.
What is at stake is the water supply for the Monterey
Peninsula. Consuming water drawn from the Carmel River is no
longer feasible, neither ecologically nor legally. But the
power to decide on an alternative supply is largely vested in
the hands of public officials from outside the region.
The golf course property, now earmarked by its nonprofit owner
the Trust For Public Land for “rewilding” after a fierce
community battle over its future, sits in the headwaters of the
Lagunitas Creek watershed. The watershed … is a spawning and
rearing ground for coho salmon and steelhead trout, both of
which are on the endangered species list.
The nation’s coasts were hit with increased tidal flooding over
the past year, part of a costly and perilous trend that will
only worsen as sea levels continue to rise, federal scientists
Global warming is putting lake fish in hot water, with
worrisome possibilities for many species, as well as the
nation’s fishermen and the $115 billion sport fishing industry
that employs as many as 820,000 people.
The water is coming straight from the Sierra Nevada Mountains
and is very cold, which is causing some concerns people hoping
to get into the water. But, the water itself, when used what
it’s intended for, has a great impact in our Central Valley.
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
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.
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.
Industry veteran Gloria Gray took the helm at the Metropolitan
Water District of Southern California. In this interview, Gray
