An ecosystem includes all of the living organisms (plants,
animals and microbes) in a given area, interacting with each
other, and also with their non-living environments (air, water
Ecosystems are dynamic and are impacted by disturbances such as a
drought, an extraordinarily freezing winter, and pests.
Longer-term disturbances include climate change effects.
Ecosystems provide a variety of goods and services upon which
people depend. Ecosystem management emphasizes managing natural
resources at the level of the ecosystem itself and not just
managing individual species.
The California Legislature was the first in the country to
protect rare plants and animals through passage of the California
Endangered Species Act in 1970. Congress followed suit in 1973 by
passing the federal Endangered Species Act.
A dialogue organized by Stanford that brought together
environmental organizations, hydropower companies, investors,
government agencies and universities has resulted in an
important new agreement to help address climate change… Dan
Reicher, a former U.S. assistant secretary of energy and board
member of the conservation group American Rivers, spoke with us
about brokering this new agreement…
The Federal Emergency Management Agency has taken a dramatic
step to encourage communities to use environmentally friendly
features such as wetlands for flood protection instead of
building sea walls and levees.
This moment in time provides an opportunity for introspection,
a time to think about our families and friends, what is
essential in our lives, and how we can contribute to population
health and wellness. In the Sacramento Valley … our team is
working hard to envision the role that water suppliers and
local governments can serve to help people live healthier and
more fulfilling lives.
Droughts usually leave individual trees more vulnerable to
subsequent droughts. “Compounding extreme events can be really
stressful on forests and trees,” says Anna Trugman, assistant
professor in the geography department at the UC Santa Barbara.
She compares the experience to a person battling an illness:

The [Butte] county’s Forest Health Watershed Coordinator Wolfy
Rougle said there is indeed reason to worry about preventing
toxic runoff quickly, particularly with the magnitude of the
North Complex fires’ destruction, and the county’s resources
are stretched thin…So small nonprofit organizations typically
have boots on the ground to do the work with concerned
residents, like the Camp Fire Restoration Project.
Several years into the research at the California Critical Zone
Observatories, a multiyear drought lasting from fall 2011 to
fall 2015 hit the state, causing massive tree death in the
southern Sierra, while in Northern California there was
essentially none. The massive die-off in the Sierra was a
wake-up call for land managers and researchers alike…
A new California Biodiversity Collaborative will help determine
how to carry out an executive order from Gov. Gavin Newsom

The industry that operates America’s hydroelectric dams and
several environmental groups announced an unusual agreement
Tuesday to work together to get more clean energy from
hydropower while reducing the environmental harm from dams, in
a sign that the threat of climate change is spurring both sides
to rethink their decades-long battle over a large but
contentious source of renewable power. The United States
generated about 7 percent of its electricity last year from
hydropower, mainly from large dams built decades ago, such as
the Hoover Dam, which uses flowing water from the Colorado
River to power turbines.
The U.S. Environmental Protection Agency (EPA) has announced a
$108 million Water Infrastructure Finance and Innovation Act
(WIFIA) loan to the Stockton Public Financing Authority to help

Off the coast of California this August a sea monster of record
size was spotted: a patch of warm water that grew to the size
of Canada, 9.8 million square kilometers simmering up to 4
degrees Celsius warmer than usual. … Researchers are now
scrambling to chart or anticipate the impacts…
Prescribed burning … targets brush, grasses, and other
accumulated vegetation, along with dead and downed trees, to
improve ecosystem health and reduce the fuels that power
wildfires. … “We’re trying to encourage a cultural shift in
our relationship with wildfire,” says Sasha Berleman, a fire
ecologist who runs a prescribed burn training program based in
the San Francisco Bay Area. “Fire isn’t going away, so let’s

Protecting intact peatlands [such as those in California] and
restoring degraded ones are crucial steps if the world is to
counter climate change, European researchers said Friday. In a
study, they said peat bogs, wetlands that contain large amounts
of carbon in the form of decaying vegetation that has built up
over centuries, could help the world achieve climate goals like
the limit of 2 degrees Celsius of postindustrial warming that
is part of the 2015 Paris agreement.
The Forest Service’s use of herbicides and pesticides has
raised occasional alarm from environmental groups, which point
to the chemical’s potential to harm wildlife or water supplies,
or to have long-term effects on people who apply them. In some
regions, they say, scarcely a tree-planting project occurs
without the use of chemical herbicides.
After nearly 25 years of unprecedented stewardship of the upper

Water providers in California face myriad challenges in
sustainably providing high quality drinking water to their
customers while protecting the natural environment. In this
blog post, I explore the stresses
that surface and
groundwater quality challenges pose for California’s
retail water agencies.
The federal Environmental Protection Agency earlier this year
declined to regulate perchlorate, which has been linked to
thyroid conditions. The unanimous vote from the State Water
Resources Control Board is the first step toward tightening
California’s drinking water standard, currently set at 6 parts
per billion. The chemical has been found in 27 counties
The bill, which was written by state Sen. Ben Hueso, also aims
to address some of the binational challenges in managing the
watershed. The plan that the California EPA is putting together
will create a framework for how California can work with the
Mexican and U.S. governments.
Naturally when I say, “cold water,” what comes to mind are
lakes, rivers, wetlands, delta, estuaries and even reservoirs.
These are the areas that I spend the most time fishing,
boating, swimming, rafting etc. However, our natural cold-water
resources include a few lesser-known components that are just
as important to the entire operating system.
Reclamation has identified a significant seismic risk problem
at Shasta Dam that may preclude the enlargement of Shasta Dam

In the area that the Moapa Valley Water District serves, water
users are facing an uncomfortable future: People are going to
have to use less water than they were once promised. Over the
last century, state regulators handed out more groundwater
rights than there was water available. Today state officials
say that only a fraction of those rights can be used, which
could mean cuts.
Developing a lithium industry in California’s Salton Sea, an
area that experts think could supply more than a third of
lithium demand in the world today, could help set up a
multi-billion dollar domestic supply chain for electric vehicle
batteries, according to a new report from New Energy Nexus.
A federal judge ruled Monday that a sprawling collage of salt
ponds in Redwood City is subject to protection under the Clean

Among the largest wildfires in California history, the LNU
Lightning Complex fires killed five people and destroyed nearly
1,500 structures — including whole blocks of the Berryessa
Highlands neighborhood where Kody Petrini’s home stood. Camped
out in a trailer on his in-laws’ nearby lot, the 32-year-old
father of two, along with all of his neighbors, was warned not
to drink the water or boil it because it could be contaminated
with dangerous compounds like benzene…
In California’s Placer County, an unusual partnership between a
county water utility, the U.S. Forest Service and
environmentalists is taking on the work to prevent catastrophic
fires on more than 11,000 hectares in the northern Sierra
Nevada Mountains. The partnership arose from the ashes of
2014’s King fire.
Biologists and engineers are setting the stage for an
environmental recovery effort in downtown Los Angeles that
could rival the return of the gray wolf, bald eagle and

U.S. and tribal officials are celebrating completion of a $34
million fish bypass system at a Nevada dam that will allow a
threatened trout species to return to some of its native
spawning grounds for the first time in more than a century.
Construction of the side channel with fish-friendly screens is
a major step toward someday enabling Lahontan cutthroat trout
to make the same 100-mile journey — from a desert lake
northeast of Reno to Lake Tahoe atop the Sierra — that they did

If you look closely in the waters of Deer Creek, near Nevada
City, Calif., something strange may catch your eye; lying in
globules amongst the gravel is quicksilver, or liquid elemental
mercury. Carrie Monohan, head scientist for the Sierra Fund,
lives next to Deer Creek, and became concerned about mercury
contamination in the waterways when she pulled liquid mercury
from the water in a turkey baster.
According to river flow data, there is currently almost no
water flowing into Walker Lake, a common condition. Today,
where the riverbed meets the lake is an ooze of mud. The lake
is all but biologically dead. But a decades-old public trust
lawsuit made a move forward in its glacial process through
federal courts last week, and advocates are hopeful Walker
Lake, a cornerstone of the regional economy and ecology, can
one day be revived.
On Wednesday, the Bureau of Reclamation joined its partners,
U.S. Fish and Wildlife Service and Farmers Conservation
Alliance, to celebrate the completion of the Derby Dam Fish
Screen Project. The infrastructure modernization project at
Derby Dam will provide Lahontan Cutthroat Trout access to
natural spawning grounds for the first time since 1905.
When Jay Rowan learned in late April that trout in California
hatcheries were exhibiting strange symptoms, he had been the
hatchery production manager for California’s Department of Fish

operations after the coronavirus lockdowns, Mr. Rowan began to
worry that a second crisis was on the way.
Four days before dry lightning ignited this year’s statewide
wildfire siege, state and federal leaders signed an agreement
to vastly expand vegetation management in California. This
signals progress towards shared management of forests to reduce
the risk of large severe wildfires and improve their resilience
to the changing climate. … But are current funding sources
enough to keep pace?
Gov. Gavin Newsom on Tuesday added his signature to a new law
that orders the formation of a commission to study the
feasibility of lithium extraction around the Salton Sea. Local
politicians hope the commission will lead to the creation of a
green economy around the state’s largest lake, which is a
geothermal hotspot. It was one of several bills focused on
California’s environment that Newsom dealt with this week.
Assessments of the worst-case scenario predict the Bay may rise
a damaging 1.9 feet by 2050 and as much as nearly 7 feet by

Some of the largest users of the Ventura River recently
released their proposal to settle litigation and potentially
stave off a water-rights adjudication. The plan includes
multiple habitat restoration projects intended to help
endangered steelhead trout, but largely avoids any changes to
water use. Before it goes to a judge, however, other parties
likely will weigh in, including the state.
The proposed ecological wetland park at Alameda Point, known as
DePave Park, is another step closer to becoming a reality. On

The monsoon season — that period from mid-June through
September that each year brings rains to the Mojave Desert and
other areas of the Southwest from the tropical coast of Mexico
— has been a dud this year. Las Vegas is in the middle of a

Climate change is driving the scale and impact of recent
wildfires that have raged in California, say scientists. Their
analysis finds an “unequivocal and pervasive” role for global
heating in boosting the conditions for fire. California now has
greater exposure to fire risks than before humans started
altering the climate, the authors say.
While more than half of California’s forests fall under federal
management, the U.S. Forest Service consistently spends fewer
dollars than the state in managing those lands to reduce
wildfire risks, a Reuters data analysis reveals. The relative
spending by federal and state forest authorities undermines
President Donald Trump’s repeated attempts to blame deadly
wildfires on a failure by California to clear its forests of
dead wood and other debris.
In a congressional hearing Thursday that starkly illuminated
partisan divides, California Democrats called on the federal

steps in managing floodplains for salmon.
Practically every drop of water that flows through the meadows,
canyons and plains of the Colorado River Basin has reams of
science attached to it. Our latest article in Western
Water news examines a new report that synthesizes and
provides context for that science and could aid water managers
as they prepare to rewrite the operating rules for a river
system so vital to the Southwestern United States and Mexico.
A crisis could be approaching. The two giant reservoirs on the
Colorado River are both below 50 percent of capacity. If
drought causes even more drastic drops, the Bureau of
Reclamation could step in to prioritize the making of

Along with being a global leader on addressing climate change,
California is the seventh-largest producer of oil in the
nation. And across some of its largest oil fields, companies
have for decades turned spills into profits, garnering millions
of dollars from surface expressions that can foul sensitive
habitats and endanger workers, an investigation by The Desert
Sun and ProPublica has found….Under state laws, it’s illegal
to discharge any hazardous substance into a creek or streambed,

are set to hear Texas v. New Mexico, virtually, on their first
day of oral arguments Oct. 5. Here’s how original jurisdiction
water cases work, what’s at stake this term, and what’s on the
For years, a stretch of Chorro Creek near Hollister Peak ran
through active farmland, where its flow was diverted for
irrigation and its banks were shored up by levees, blocking the
water’s natural access to its floodplain. … After nearly two
decades of planning and fundraising, the Estuary Program and
its partners recently completed a major restoration of the
The Nevada Supreme Court ruled Thursday that the state cannot
reshuffle existing water rights to prevent environmental
damage, despite recognizing a legal principle that requires the
government to preserve natural resources for future
generations… The Nevada court, in a 4-2 decision, separated
itself from the California Supreme Court, which reached the
opposite conclusion in a landmark 1980s case.
Through research funded by the Almond Board of California we
are exploring ways to recharge groundwater aquifers, be good
stewards of the water that we all collectively share as a
state, and even helping the salmon industry understand how
agricultural land, like rice fields, could play a role in
supporting salmon health.
When fires burn up vegetation, the charred remains become
hydrophobic—meaning they repel away any water. The soil is also
very dry, which counterintuitively makes it harder for water to
infiltrate. … Fires can also destroy the natural clumps in
soil, increasing their erodibility. Altogether, this means that
water is hitting the ground with more force and the soil is
unable to suck it up.
A top water regulator from New Mexico yesterday warned senators
that hardrock mines, wastewater facilities and other industrial
entities could face stricter environmental oversight as the
Trump administration’s Waters of the U.S., or WOTUS, rule takes
Poor erosion control on the 258-acre site unleashed soils into
streams of the Russian River watershed and put fish and other
other aquatic wildlife at risk, regulators found, counteracting
millions of dollars spent to improve habitat and restore
imperiled, protected runs of salmon and steelhead…
Along a Huntington Beach coastline dotted with oil rigs and a
power plant, one of California’s largest remaining saltwater
marshes has been a source of pride for local environmentalists.
But the marsh, known as the Bolsa Chica Wetlands, is endangered
despite a years-long struggle to pull together sufficient
public funding for its upkeep.
When the Creek Fire exploded to 160,000 acres in just 72 hours,
ripping through a jewel of the Sierra Nevada just south of
Yosemite National Park, California and the world looked on in
horror and surprise. But the stage had long been set for the
megablaze, one of a half-dozen transforming millions of acres
of Golden State landscapes to ash. Droughts supercharged
by climate change dried out vegetation, aiding its transition
A team of scientists, led by the University of Arizona, has
developed a new blueprint for arid-land agriculture using wild,
native crops and modern growing techniques. The 14 researchers
from the Southwest and Mexico believe their model can produce a
sustainable, local source of food that will improve the health
and well-being of consumers and farmworkers alike.
The right balance of nutrients is crucial for a healthy coastal
ecosystem. If rivers deposit too much nitrogen and phosphorus
in coastal areas, algae that flourish on those nutrients can
cause dead zones; if too little silicon flows downstream,
organisms that depend on it will die off.
Former U.S. Secretary of the Interior Bruce Babbitt writes that
a “Grand Bargain” in California water is needed to end the
“political culture of deferral” and allow major water projects
to advance. On the contrary, what’s needed is an adult
regulator that will make hard choices that water users refuse
We recommend issuing “Do Not Use” orders in the wake of major
fires to protect the public before water testing results are
available. We believe it is acceptable to use water for fire
fighting and toilet flushing, but not for purposes that involve
ingestion, skin exposure or inhalation, such as bathing or
Scientists at Salo Sciences, a startup that works on technology
for natural climate solutions, began creating the tool after
interviewing dozens of experts in California about the state’s
challenges with wildfires: They need more detailed, up-to-date
information about the forests so they can better predict how
fast and in what direction fires will spread…
The Sierra Nevada provides more than 60 percent of California’s
water supply and sustains a globally important agricultural
region. Quantifying the water-related benefits can be critical
in showing the true value and cost-benefit of forest
management. But until now, there hasn’t been enough locally
relevant data to incentivize restoration projects.
Wildfires started burning in California early again this dry
season—more than two million acres have burned so far. Larger
and larger wildfires are occurring as new heat records are
being broken each year. Firefighting efforts have leaned
heavily on aerial spraying of fire retardants, but their
environmental and health effects [including on fish and
waterways] are little studied …
Responding to the lack of progress in 2017, the State Water
Resources Control Board ordered the California Natural
Resources Agency to adopt a 10-year plan to implement projects
to suppress the harmful dust and restore habitat. … But in
the three years since the water board’s order, progress has
been dismal, even though there is more than $350 million
available to implement the plan.
This proposal by California American Water has become one of
the most complicated and fraught issues to come before the
California Coastal Commission, whose long-awaited vote on
Thursday could determine not only the contentious future
of water on the Monterey Peninsula — but also the role of
government in undoing environmental inequity.
Every September for the last 22 years, the South Yuba River
Citizens League has hosted a Yuba River Cleanup with the help
of the California Coastal Commission. This year, the river’s
need for some tender, loving care has only grown as the region
reckons with more visitors, more single-use plastics and less
accountability amidst the pandemic.
New mapping of salt concentrations in the world’s oceans
confirms what physics and climate models have long suggested:
Global warming is intensifying Earth’s water cycle, speeding up
the rate at which water evaporates in one area and falls as
rain or snow somewhere else. That intensification has enormous
implications because it worsens droughts and increases extreme
rainstorms and flooding.
In recent years, nearly 150 million trees died around the state
as their roots delved fruitlessly for water and a devastating
bark beetle infestation took hold. Both the drought and the
insect spread that came with it were exacerbated by changing
climate conditions linked to humans burning fossil fuels,
scientists concluded. Now those trees, like so much else in the
American West, are burning as California contends with a
reckoning more than 100 years in the making.
Dizzying in its scope, detail and complexity, the scientific
information on the Basin’s climate and hydrology has been
largely scattered in hundreds of studies and reports. Some
studies may conflict with others, or at least appear to. That’s
problematic for a river that’s a lifeline for 40 million people
and more than 4 million acres of irrigated farmland.
While working at the United Water Conservation District,
Michael Booth used 19 years of records from a designated fish
trap on southern California’s Santa Clara River to identify
potential environmental drivers that spur some fish to make the
arduous trip to the Pacific Ocean. … He found that steelhead
migration was triggered by the lengthening daylight of spring
rather than factors like recent rains…
The Monterey Peninsula is about to find out if a long-term
water supply will become a reality on Thursday as California’s
Coastal Commission is scheduled to hear the application for a
permit to build the desalination source water wells. The Farm
Bureau believes the permit is necessary to secure a reliable
water supply for Peninsula residents and businesses.
One of the most severe examples is the San Lorenzo Valley Water
District, which serves parts of inland Santa Cruz County, in
central California. More than 7 miles of an HDPE plastic water
supply pipeline were destroyed in the CZU Lightning Complex
Fire, according to Rick Rogers, the district manager.
The White House’s rewrite of National Environmental Policy Act
rules is set take effect as planned this month, after a federal
judge on Friday declined to freeze the measure. The decision is
a victory for the Trump administration’s efforts to speed up

As wildfires burn across California, temperatures hit record
highs, and communities cope with the COVID-19 crisis,
biologist Caroline Brady is helping respond to a different
disaster: the worst avian botulism outbreak that anyone can
remember at the Klamath Basin National Wildlife Refuge Complex.
Lake Powell isn’t in Southern Nevada. Rather, it’s about four
hours away by car in southern Utah. But some environmentalists
say the water consumption of St. George, Utah, and neighboring
communities could have a direct and deleterious impact on the
Las Vegas water supply.
Reclamation announces a virtual open house website for the
Shasta Lake Water Resources Investigation Draft Supplemental
Environmental Impact Statement. Website visitors will be able
to learn more about the project, review summaries of Draft
Supplemental EIS chapters, and submit comments.
The idea was to lower the flows while temperatures were still
warm enough to dry out the caddis larvae. That required buy-in
from local merchants and the Bureau of Reclamation, local
tribes and others. They were able to do it, and on Aug. 27, the
first of two flow reductions took place. When the river
dropped, people pitched in for a day of river cleanup.
Mike Halpert, deputy director of the Climate Prediction Center,
said that as a result of La Niña, Southern California, as well
as most of Arizona and New Mexico, could “tilt toward dry” this
winter. Southern California, which gets most of its rainfall
from late fall to early spring, is already abnormally dry…
The San Francisco Bay-Delta is literally threatened from all
sides: rising sea levels from the ocean, disruptions to
sediment supply from upstream, and within the Bay-Delta itself,
development and other land use changes have left only a tiny
fraction (5%) of marshland untouched. … A recent study by
scientists at the U.S. Geological Survey used historical
streamflow and sediment data to predict what will happen to the
Bay-Delta under varying levels of climate change.
“When a forest burns in a wildfire, should we expect it to
return as it was before?” Research scientist Jonathan Coop and
his team pose this question. It addresses a critical conundrum
in ecology: How do ecosystems recover from disturbance and why?
At the August meeting of the Delta Independent Science Board,
the new members joined with the outgoing members for

Coal miners, stone quarrying companies, and other businesses
are rushing to lock down any exemptions to federal water
jurisdiction for at least five years, under changes the Trump
administration recently made to the nation’s water rule. … A
decision that might in some instances have taken multiple site
visits and nearly three years now can come as quickly as a day,
the data show.
The pending removal of the Upper York Creek Dam has put a stop
to a daily $70 fine that’s been levied against the City of St.
Helena for almost eight years. Thanks to rapid progress on the
long-awaited project, which will improve fish passage and
restore habitat along York Creek, the National Oceanic and
Atmospheric Administration has suspended the $70 per day
penalty the city has incurred since November 2012…
There is something in the water on planet Earth. A study
published Wednesday reveals climate change has amplified the
water cycle, which explains the more frequent extreme weather
patterns in recent years.
While California’s climate has always made the state prone to
fires, the link between human-caused climate change and bigger
fires is inextricable, said Park Williams, a bioclimatologist
at Columbia University’s Lamont-Doherty Earth Observatory.
In Protecting Our Water and Environmental Resources v. County
of Stanislaus, the Court held that the County may not
categorically classify all groundwater well permit issuances as
ministerial decisions. Such a classification exempts well
permit issuances from environmental review.

The most pressing risk is debris that could clog the San
Lorenzo River near River Street and Highway 1 where water
enters the city’s system, said Santa Cruz Water Director
Rosemary Menard. The San Lorenzo River is the city’s largest
water source. It represents about 45% of the water supply.
Irvine Ranch Water District and Rosedale-Rio Bravo Water
Storage District had just begun environmental review for their

liberally applied to Central Valley farmland from the 1950s
through the 1980s.
If current predictions hold, the entire Palo Alto Baylands
could be submerged by the middle of the century because of sea
level rise, a destructive predicament that would threaten both
the sensitive habitat and the critical infrastructure in the

moving ahead with the creation of a new Sea Level Adaptation
Restoring specific “functional flows” would better support fish
migration and spawning, water quality, dry-season base flows,
and physical conditions that support aquatic species. A panel
of experts, moderated by PPIC senior fellow and study coauthor
Jeff Mount, discussed how to put this approach into practice.

By killing millions of trees in the Sierra National Forest, the
historic drought that ended in 2017 left an incendiary supply
of dry fuel that appears to have intensified the fire that’s
ravaged more than 140,000 acres in the southern Sierra Nevada,
wildfire scientists and forestry experts said.
The results of targeted sampling for more than 80 lakes and
rivers are summarized in an interactive map showing which sites
were tested at each waterbody. The map indicates the specific
tiered recreational health advisory level — “Caution,”
“Warning” or “Danger” — based on cyanotoxin testing results
and/or visual indicators confirming presence of a harmful algal
In 2010, tribes joined the company that owns the dams and other
stakeholders in an agreement to remove the dams in 2020. The
plan was later delayed to 2022, and now it may stall again
because of a recent decision by federal regulators.
The test they want to use measures total organic fluorine
amounts in water and can provide a broader picture of all per-
and polyfluoroalkyl substances (PFAS) in a sample instead of
testing for one or a few substances at a time. By removing the
need to test for individual PFAS, states may be able to speed
up the process for regulating groups of the chemicals, some of
which have been linked to cancer.
The water wars are far from over, a point made clear in a
just-released feature-length documentary, “Until the Last

combination of dripping water with a fight to the last drop of
Arizona’s top water regulator has endorsed a company’s proposal
to take water from farmland near the Colorado River and sell it
to the fast-growing Phoenix suburb of Queen Creek. The plan,
which still would require federal approval, has generated a
heated debate about whether transferring water away from the
farming community of Cibola could harm the local economy, and
whether the deal would open the gates for more companies to buy
land near the river with the sole aim of selling off the water
Wildfires have burned more than 2 million acres in California
this year, setting a state record even as crews battled dozens
of growing blazes in sweltering temperatures Monday that
strained the electrical grid and threatened power outages for
millions. The most striking thing about the record is how early
it was set, with the most dangerous part of the year still
ahead…About 30 houses were destroyed in the remote hamlet of
Big Creek, … [but] a school, church, library, historic
general store and a major hydroelectric plant were spared…

Americans support far more aggressive government regulation to
fight the effects of climate change than elected officials have
been willing to pursue so far, new research shows, including
outright bans on building in flood- or fire-prone areas — a
level of restrictiveness almost unheard-of in the United
States…in California and elsewhere, officials continue to
approve development in areas hit by fires.
Starting in mid-July, the flows in the Noyo River began
dropping faster than in any other summer on record. The river
flow is below 2015 low flows, when the entire state was in a
drought emergency. John Smith, director of Fort Bragg Public

At their regular meeting Tuesday, Sept. 1, the Siskiyou County
Board of Supervisors discussed issues that Big Springs area
residents are still facing regarding alleged privatized water
sale for illegal marijuana grows. Despite an urgency ordinance

alleged extraction sites on Aug. 22, residents say they’re
still noticing trucking going on.
Four aging dams on the Klamath River are coming down. Their
completion between 1921 and 1964 brought hydroelectric power to
Northern California. It also blocked hundreds of kilometers of
fish habitat, causing Chinook salmon to effectively disappear
from the upper river basin. But the removal of dams is no
guarantee the fish will return, so a team of wildlife
researchers hopes it can coax the fish to repopulate the river
by exploiting a new discovery about salmon genetics.
For the first time in years, boats will soon be able to travel
