water necessary to balance the groundwater basin. A public
hearing regarding the fee is scheduled for 10 a.m. Aug. 21 at
Like other environmental regulations, WOTUS was necessarily
complex and grounded in science. But the reason for it was
simple: keep U.S. waters clean. So what could be so bad about a
law to stop water pollution that the Trump administration would
decide to repeal it?
If built, it would … pump groundwater into four new
reservoirs … Tribal members and environmentalists say the
project would flood several miles of canyons sacred to the
Navajo; risk damaging cultural sites for several tribes; draw
vast amounts of critical groundwater; potentially harm habitats
for plants and animals, including some endangered species; and
risk adverse effects for waterways leading into the Grand
Within as little as 50 years, many regions of the United States
could see their freshwater supply reduced by as much as a
third, warn scientists. … Shortages won’t affect only the
regions we’d expect to be dry: With as many as 96 out of 204
basins in trouble, water shortages would impact most of the
U.S., including the central and southern Great Plains, the
Southwest, central Rocky Mountain states, as well as parts of
After years marked by a historic statewide drought and
devastating floods around downtown San Jose, Santa Clara
County’s largest water provider has decided to ask voters to
approve a parcel tax to pay for a wide variety of projects,
from flood control to creek restoration, along with some costs
of rebuilding the county’s largest dam at Anderson Reservoir.
Every day Hyperion Water Treatment Plant discharges enough
treated wastewater into the ocean to fill the Rose Bowl 2.5
times over. Now a court has instructed state water officials to
analyze whether it is “wasteful” and “unreasonable” to dump
billions of gallons of wastewater into the sea.
The California Advisory Committee on Salmon and Steelhead Trout
was re-established by the Legislature in 1983 in response to
public concern about declining populations of salmon and
steelhead. … At the July meeting, committee members received
an update on the Klamath dams, Matilija Dam, and the Potter
Valley Project dam removal projects.
By the 2070s, climate change will reduce snowpack and increase
extreme rainfall in the Sierra Nevada and California’s
reservoirs will likely be overwhelmed. That’s according to a
new study by UCLA climate scientists, who predict that run-off
during so-called atmospheric rivers will increase by nearly 50
percent, leading to widespread flooding across the state.
Six former Environmental Protection Agency
chiefs [who served under Republican and Democratic
presidents] are calling for an agency reset after President
Trump’s regulation-removing, industry-minded first term,
backing a detailed plan by former EPA staffers that ranges from
renouncing political influence in regulation to boosting
climate-friendly electric vehicles.
After timber harvest or fuel reduction thinning operations,
sediment delivery to nearby streams and waterways can increase,
potentially affecting water quality, drinking water supplies,
habitat, and recreational opportunities. To effectively reduce
these adverse effects of harvest, foresters first need to know
the precise causes of sediment increases.
A win for state water rights came earlier this month after the
Marion County Circuit Court ruled that the Bureau of
Reclamation cannot release water from Upper Klamath Lake for
flows down the Klamath River.
Supporters of an initiative to reduce plastic waste today
submitted more than 870,000 voter signatures to qualify the
Plastics Free California initiative for the ballot –
significantly more than the 623,212 signatures required.
The Los Angeles Superior Court issued a historic ruling, in
favor of Los Angeles Waterkeeper, that compels the State Water
Resources Control Board to analyze whether it is “wasteful” and
“unreasonable” to dump billions of gallons of wastewater
uselessly into the sea, when it could instead be used
productively to ensure the sustainability of California’s water
As vehicular travel of any kind is prohibited, the wilderness
in Imperial County is visited by only a few hikers and an
occasional Border Patrol officer. However, the construction of
the border wall has brought a flurry of activity that could
lead to profound and irreversible environmental changes to the
area. …this border wall construction could exacerbate
the problem of limited access to water.
The loss in hydroelectric generation during the 2012-16 drought
cost PG&E and other California utilities about $5.5
billion, a new study says. As California’s climate becomes more
prone to severe droughts, the findings point to future costs
that utilities — and ultimately ratepayers — will likely be
forced to bear.
Recent conditions across California over the past 3-5 weeks
have been pretty typical by mid-summer standards. …
California’s boon, however, has been Arizona’s misfortune: a

A group dedicated to protecting the Ballona Wetlands is among
the plaintiffs in a lawsuit alleging millions of dollars in
public funds have been misused for what they claim is a
“deceptive” plan to bulldoze the ecological reserve under the
guise of being a restoration effort.
Regional San’s landmark recycled water program—previously known
as the South County Ag Program—has been rebranded. Now known as
Harvest Water, the program will be one of the largest water
recycling projects in California and will deliver up to
50,000-acre feet per year of tertiary-treated recycled water to
an estimated 16,000 acres of farm and habitat lands in southern
By the 2070s, global warming will increase extreme rainfall and
reduce snowfall in the Sierra Nevada, delivering a double
whammy that will likely overwhelm California’s reservoirs and
heighten the risk of flooding in much of the state, according
to a new study by UCLA climate scientists.
FERC concluded that the nonprofit that was going to take
ownership of the dams didn’t have the experience or expertise
to oversee such a complicated project. PacifiCorp therefore
needed to stay on as co-licensee. But if PacifiCorp couldn’t
walk away clean, it lost a huge incentive for removing the dams
at all. It might just as well stick with the status quo.
Hot and dry conditions pushed portions of Arizona, southern
Nevada and Southern California either into drought or further
into drought, data from the U.S. Drought monitor show. … The
North American Monsoon, which provides about half of the annual
rainfall in parts of the Southwest, has been a “nonsoon” this
year … The portion of California deemed abnormally
dry grew by almost 7%, mainly in eastern San Bernardino
People hoping to get a handle on future droughts in the
American West are in for a disappointment, as new University of
Southern California-led research shows El Niño cycles are an
unreliable predictor. Instead, they found that Earth’s dynamic
atmosphere is a wild card that plays a much bigger role than
sea surface temperatures, yet defies predictability, in the wet
and dry cycles that whipsaw the western states.
The Regional Water Quality Control Board concluded three days
of hearings on the project’s next permit by telling Poseidon it
must return with a more robust, more detailed mitigation plan
to offset the environmental damage the project will cause.
The suit, spearheaded by the Natural Resources Defense Council
on behalf of eight other groups, is the third to contest the
July rollback of the National Environmental Policy Act (NEPA),
which for 50 years has required thorough environmental reviews

In California, many of the wildfires occur in the Sierra Nevada
mountains, which are the source of 70% of California’s water
resources. Understanding the feedbacks and implications of
disturbances on the hydrological cycle can help watershed
managers plan for future scenarios with wildfires and climate
Forest-management actions such as mechanical thinning and
prescribed burns don’t just reduce the risk of severe wildfire
and promote forest health — these practices can also contribute
to significant increases in downstream water availability. New
research from UC Merced’s Sierra Nevada Research Institute
provides the tools to help estimate and verify those changes.
In the 2020–2021 session, the Court likely will issue rulings

The decades-long battle over an effort to raise the height of
Shasta Dam took another turn Thursday when the Trump
Administration released a new environmental report on the plan,
just five years after completing a similar study.
Our newest video features our ongoing project to study the
non-native fishes of the San Joaquin River in California’s

Signal crayfish are displacing Shasta crayfish. Believed to
have already forced the sooty crayfish (Pacifastacus
nigrescens) to extinction, signal crayfish have outcompeted
their Shasta cousins to near extinction. However, a growing
trend of environmental monitoring, typically referred to as
eDNA, is helping scientists isolate the scarce species in an
effort to save it.
Under the Aug. 3 proposal, companies would no longer be
required to notify the Army Corps if the pipelines they lay

longer than 500 feet with fill material dredged from streams or
wetlands or with impervious materials.
The Oregon Cattlemen’s Association sued the EPA and the U.S.
Army Corps of Engineers in May for bringing non-navigable,
small streams and wetlands under Clean Water Act protection in
the Navigable Waters Protection Rule. Judge Michael W. Mosman,

Disparities across the environment, the economy, and COVID-19
are inextricably linked to race/ethnicity and disproportionally
affect communities of color. At the same time, people of color
are more likely than whites to be concerned about these
inequities. PPIC’s latest survey on environmental issues takes
a closer look at Californians’ views.
Some have found fishing the L.A. River to be a peaceful respite
from COVID-19, political and social turmoil and malaise of all

As Poseidon Water pursues the final government approvals needed
to build one of the country’s biggest seawater desalination
plants, the company still cannot definitively say who will buy
the 50 million gallons a day of drinking water it wants to

The COVID-109 pandemic isn’t slowing work aimed at moving
arguably the most cantankerous water project ever proposed in
California since voters overwhelmingly rejected the Peripheral
Canal in 1982 — the Delta Tunnel Project. … The State
Department of Water Resources is currently preparing an
environmental impact report on the project. At the same time
they are also seeking all required state and federal approvals.
Failure to account for the long-term trend of declining per
capita water demand has led to routine overestimation of future
water demand. This can lead to unnecessary and costly
investment in unneeded infrastructure and new sources of
supply, higher costs, and adverse environmental impacts.
Crops require water to grow. By importing water-intensive
crops, countries essentially bring in a natural resource in the
form of virtual water. Agricultural virtual water is the amount
of water needed to grow a particular crop in a given region.
Now research led by scientists at PNNL has projected that the
volume of virtual water traded globally could triple by the end
of the century.
A California company that produces Crystal Geyser bottled water
was sentenced Wednesday to three years of probation and ordered
to pay $5 million in fines for illegally storing and
transporting hazardous waste, federal prosecutors said. The
waste was produced by filtering arsenic out of Sierra Nevada
spring water at CG Roxane LLC’s facility in the Owens Valley.
The act, which allocates $900 million a year to the Land and

decision, citing environmental concerns.
Through three governors, California has set a path to tear down
four aging dams on the Klamath River astride the Oregon border.
It would be the biggest such removal project in the nation,
done in the name of fish preservation, clean water flows and
political consensus. But the undertaking is hitting a snag, one
that Gov. Gavin Newsom wants to undo.
Deep beneath the surface of the Salton Sea, a shallow lake in
California’s Imperial County, sits an immense reserve of
critical metals that, if unlocked, could power the state’s

Among the projects, the bureau promises to update a 20-year-old
assessment of streamflows in the lower Klamath River for Coho
salmon and re-evaluate how water levels in Upper Klamath Lake
are affecting the survival of endangered sucker fish. Farmers
in the Klamath Project have long argued that flawed or outdated
science is chipping away at the amount of water they receive
each year to irrigate crops.
When Brenda Goeden first started working on mud, silt, and sand
in the San Francisco Bay two decades ago, dredgers and
contractors couldn’t get rid of all the sediment they excavated
fast enough. … But today sediment is a hot commodity, as
restorationists and developers scramble to elevate salt marshes
and building sites before rising tides claim them. Now, a new
plan is in the works to optimize allocation of this critical
The San Francisco Bay-Delta is among the most intensively
studied ecosystems in the world. Numerous long-term fisheries
monitoring programs have been conducted there since the late
1950s, but differences in the methods, scope, spatial coverage,

In September 2018, Estela Escoto sat down with a team of
lawyers and community organizers and weighed her options.
Escoto’s town—Arvin, California—had just granted an oil
drilling and well-servicing company, Petro-Lud, a permit to
drill four new wells near a neighborhood densely packed with
young families and a park where children played soccer.
Both the Tubbs and Camp fires destroyed fire hydrants, water
pipes and meter boxes. Water leaks and ruptured hydrants were
common. … After the fires passed, testing ultimately revealed
widespread hazardous drinking water contamination. Evidence
suggests that the toxic chemicals originated from a combination
of burning vegetation, structures and plastic materials.
With a new water supply delayed by state regulatory agencies
and political infighting, the Monterey Peninsula Water

Droughts are common in California. The drought of 2012-2016 had
no less precipitation and was no longer than previous
historical droughts, but came with record high temperatures and
low snowpack, which worsened many drought impacts.
After hearings this week for one of two remaining major permits
needed for the project, several members of the Regional Water
Quality Control Board indicated they were dissatisfied with the
proposed mitigation for the larvae and other small marine life
that would die as a result of the plant’s ocean intake pipes.
As part of Valley Water’s mission to provide flood protection
for our communities, we are continuously preparing for the
possibility of flooding. We must regularly keep our streams and
creeks well maintained to handle the rainy season and protect
the many species of wildlife that live there.
Poseidon Resources wants to build a $1.4 billion desalination
plant near a power plant that is about to be shut down. They
say it could produce 50 million gallons of water per day,
enough for about 100,000 Orange County homes. Friday marked the
second day of hearings before the Santa Ana Regional Water
Quality Control Board. Its approval is needed for the plant to
discharge salty brine left over from the treated water.
Lake Tahoe’s fluctuating clarity got worse last year during an
especially cold and wet winter as sedimentation, algae growth
and a tiny invasive shrimp continued to pose restoration
challenges for the famed clear water of the mountain lake
straddling the California-Nevada line.
A Marin County Superior Court judge rejected a petition filed
by a group of San Geronimo residents and golfers to halt creek

Saving our planet will require unprecedented focus and
investment from every sector of our society and all levels of
government — especially the federal government. Yet when it
comes to the San Francisco Bay — a national treasure and the
lifeblood of our region, producing over $370 billion in goods
and services annually and supporting more than 4 million jobs —
the federal government has been complicit in its deterioration.
The average annual flow of the Colorado River has decreased 19
percent compared to its 20th century average. Models predict

For us, dam removal is absolutely necessary to restore our
struggling fisheries, maintain cultural practices, and provide
tribal members who struggle to make ends meet access to
traditional subsistence foods.
When species are endangered, the Endangered Species Act
requires the government to set aside habitat deemed critical
for its recovery. But environmental groups say the new
definition being proposed by the Fish and Wildlife Service will
allow the agency to block setting aside any land that isn’t
currently habitat but might be needed in the future,
particularly as the climate changes.
In the midst of a hot July after late rains this season, the
outlook for reforesting on the ridge will depend on the efforts
of private landowners, local forest scientists say. With this
help, residents of the ridge could see a new type of forest
replace what was lost in the Camp Fire.
The Indian Wells Valley Groundwater Authority’s notice of an
upcoming public hearing on a basin replenishment fee has
attracted a lot of attention from water users in the valley,
but not everyone understands what the IWVGA is.
To be clear, not all algae are dangerous. In fact the vast
majority are beneficial to ecosystems. They’re the base of the
marine and aquatic food webs, providing nutrients for fish and
shellfish, which in turn feed other animals — including people.
They also produce half of our oxygen. “But a small handful of
