California’s two primary salmon species, Coho and Chinook, have
experienced significant declines from historical populations.
Of particular importance is the Chinook salmon because the
species supports commercial fishing and related jobs and economic
activities at fish hatcheries.
The decline in salmon numbers is attributed to a variety of
manmade and natural factors including drought, habitat
destruction, water diversions, migratory obstacles created by
local, state and federal water projects, over-fishing,
unfavorable ocean conditions, pollution and introduced predator
species. Wetlands have also been drained and diked; dams have
blocked salmon from reaching historic spawning grounds.
Years of declining populations represent a significant economic
loss and have led to federally mandated salmon restoration plans
that complicate water diversions and conveyance for agriculture
and other uses.
There has likely been 95% or more decline in [coho salmon]
numbers since the 1960s in California due to dam construction
and habitat degradation from various land-use practices. Toxic
tire pollution is another threat added to the already long lost
of myriad threats this species face.
Holidays are a natural time of introspection on who we are,
what we do, and why. Towards a bit of our own self-reflection,
some researchers from UC Davis’ Center for Watershed Sciences
(CWS) have each contributed a photo and short description of
their work. We hope you enjoy reading about us and learning
even more about us. It is hopefully a soft bookend to a wild
For years, researchers have worked to solve the mysterious
cause of extreme coho salmon mortality in the Pacific
Northwest. A recent study by the San Francisco Estuary
Institute and the University of Washington has finally
identified the microscopic culprit as a highly toxic
contaminant associated with tire particles…The study focused
on water samples from the San Francisco Bay area and the Puget
Sound in Washington state, but scientists fear the contaminant
could affect coho salmon in the Eel and Klamath rivers as well.
After a record-setting season of catastrophic wildfires in
California, no single fire in 2020 burned more than the Creek
Fire in the Upper San Joaquin River watershed east of Fresno.
The Creek Fire, the largest single-source fire in California
history, ravaged nearly 380,000 acres from September to
November. Now, with 35% of the watershed burned, hydrologists
want to better understand what impact the Creek Fire may have
on spring runoff – essential to the San Joaquin Valley’s water
supply and to the welfare of a burgeoning salmon population.
The only hope for salmon to return to the Klamath River, which
runs though southern Oregon and northern California before
emptying into the Pacific Ocean, is to remove some of those
river-blocking dams because they have interfered with the
breeding habits of the fish, experts say.
Southern California steelhead are statistically the most
endangered native fish in America. In the early 1900s, hundreds
of thousands of them returned to the rivers between San Louis
Obispo and Mexico. Now, there are reportedly under a few
hundred adults returning annually.
A project to remove a major barrier to the recovery of
endangered coho salmon was completed Friday in West Marin. The
years-long effort led by the Olema-based Salmon Protection and
Watershed Network, or SPAWN, removed artificial obstacles on a
section of San Geronimo Creek for the first time in 120 years.
They had stymied the migration and survival of coho salmon and
threatened steelhead trout.
A free-flowing creek will replace Central California’s highest
priority fish passage barrier as the Salmon Protection and
Watershed Network (SPAWN) completes a community restoration
project along San Geronimo Creek [in Marin County], one of the
most important watersheds left for endangered coho salmon.
The fall salmon run is happening right now on the American
River, and for many in the greater Sacramento area, that
usually means a visit to the Nimbus Fish Hatchery to check out
the fish ladders and nearby spawning grounds. Although the
hatchery visitor center is closed because of the pandemic,
observing the salmon run can still happen, in a safe way, from
the hatchery’s nature trail.
After salmon spawn, or reproduce, it marks the end of their
lifecycle. For the Department of Water Resources (DWR) it marks
an important time for dissecting and studying salmon carcasses
to learn about the species’ population and assess their numbers
in the Feather River.
Scientists in the Pacific Northwest say they’ve solved a
long-running mystery behind the region’s dying salmon, a
discovery that may explain what’s harming fish elsewhere around
the globe, including California.
Federal and state officials signed nearly 400 treaties with
tribal nations in the 18th and 19th centuries….In recent
years, some courts, political leaders and regulators have
decided it’s time to start honoring those treaty
obligations….“The notion that tribal treaty rights should be
factored into government decision-making is gaining increasing
currency,” [said Riyaz Kanji, a leading Indian law attorney.]
The strength of that argument was on display again last month,
when leaders in Oregon and California announced plans to remove
four dams on the Klamath River.
Karuk Tribe natural resources spokesperson Craig Tucker joined
John Howard to talk about the historic agreement, its impact on
the region’s Salmon fisheries, and the potential for
replication in other places where dams are contested.
The California Natural Resources Agency recently announced the
investment of almost $50 million in Proposition 68 funding for
projects to promote salmon recovery. More than $220 million in
Proposition 1 and Proposition 68 funds have also been dedicated
for multi-benefit flood protection projects in the past two
years that will benefit salmon.
On Nov. 17, California, Oregon, PacifiCorp, and the Yurok and
Karuk Tribes announced a new agreement with the Klamath River
Renewal Corporation to reaffirm KRRC’s status as dam removal
entity and provide additional funding for the removal of four
hydroelectric dams on the Klamath River. The agreement is the
latest development in a decade-long effort…
Work crews have been busy this week along Twin Cities Road near
Courtland. They are conducting core sampling, the first step in
drafting an environmental impact report for a tunnel plan known
as the Delta Conveyance Project.
Current estimates of young salmon lost to the south Delta pumps
are based on a smattering of studies from the 1970s and should
be updated, according to a new analysis. “They don’t represent
current operations,” says Ukiah-based consultant Andrew Jahn,
lead author of the analysis reported in the September 2020
issue of San Francisco Estuary and Watershed Science.
How did two of the most important waterfowl refuges in the
United States reach such a sad state? The decline of the Tule
Lake and Lower Klamath refuges was a hundred years in the
making. There are no villains here; rather it is simply a tale
of too little water to go around on an arid landscape.
America’s largest dam removal project has been brought back to
life with a new agreement among California, Oregon, tribes and
a utility owned by billionaire Warren Buffett. The decadeslong
effort to remove four dams on the Klamath River in Northern
California that have had a devastating impact on salmon runs
had appeared in danger following an unexpected July regulatory

The Kern County Water Agency board of directors voted
unanimously to approve an agreement with the Department of
Water Resources to pay $14 million over 2021 and 2020 as its
initial share of the early planning and design phase for what’s

A research team from California State University, Chico will
continue its exceptional work to re-establish juvenile salmon
and salmonid habitats along the Sacramento River, after
learning it would continue to be funded by the United States
Bureau of Reclamation.
The last three administrations have been active in Klamath
Basin issues regardless of political party. Negotiations for a
basin-wide agreement began under the Bush Administration and
continued under the Obama Administration until faltering in the
House of Representatives — though each president’s approach has
varied. Dan Keppen, executive director of the Family Farm
Alliance, said Biden’s experience in the Obama Administration
could prove an asset, if he brings a similar approach.
A new and improved tool that tracks salmon survival in
Lagunitas Creek was installed on ranchlands west of Point Reyes
Station last month, potentially changing the way the Marin
Municipal Water District manages the watershed. Every year,
ecologists implant a rice-sized microchip in hundreds of
juvenile Coho salmon. Now, antennas anchored at the mouth of
the creek will register their passage when they swim to or from
To protect smelt and salmon, there need to be reasonable water
temperature standards in the Delta. The existing water
temperature standard in the lower Sacramento River above the
Delta is 68oF, but managers of the state and federal water
projects pay it almost no heed.
For over a century, one of the most important salmon runs in
the United States has had to contend with historic dams – and
now four of them are set to be taken down….The dams built on
the Klamath River have been identified as one cause of the
drop in salmon numbers.
California’s war with Washington over the environment will soon
come to an end. … President-elect Joe Biden has pledged to
act quickly to restore and strengthen dozens of protections on
public lands, water and wildlife. In addition, California’s
efforts to fight climate change will no longer face hurdles put
up by the White House, which has downplayed the global threat.
The recent removal of the sediment-filled York Dam in Napa
County has reconnected two miles of steelhead trout habitat
that has been blocked for over a century. … Thousands of
barriers to stream flow and fish passage similar in size and
impact to York Dam are scattered throughout California,
contributing to population declines in native fishes and other
Not only are non-native predators abundant, but predation risk
may be compounded by the prevalence of invasive vegetation such
as Brazilian waterweed (Egeria densa). These non-native plants
may deal a double blow to Chinook salmon by restricting their
access to formerly open-water habitat and by providing
predators like largemouth bass an edge in a habitat they are
Why are our food producers, including many century-old family
farms with 100-year-old water rights, facing a shortage of

A declaration suit filed in Superior Court in Sacramento by
attorneys for some of the leading environmental groups in
America accuses the California Department of Water Resources of
trying to prevent anyone in California from filing a court
action challenging … the financing of a single tunnel that

The annual migration of Chinook salmon up West Coast rivers
from the ocean has enriched ecosystems, inspired cultures, and
shaped landscapes. Yet the timing of their migration is
controlled by one small section of their genome, according to
research published this week in Science. This is the first time
scientists have linked a single gene region to such an
influential difference in a vertebrate species.
Raising salmon in the desert seems like an unlikely mission,
but that is exactly what Norwegian-based West Coast Salmon AS
intends to do. The company announced in early October it had
secured a first round of financing for a land-based Atlantic
salmon farm facility south of Winnemucca near the
Humboldt/Pershing County line.
Using a system of radio tags and electrical fields, the
equipment is expected to give researchers more accurate counts
of coho salmon that will return to Lagunitas Creek to spawn
beginning later this month as well as the young salmon leaving
the creek and entering the ocean in the spring.
Down the dark corridors of the UC Davis Watershed Sciences
building are freezers of dead fish. Frozen Chinook Salmon
carcasses and their dissected eyes and muscles in neat vials
are stacked next to White Sturgeon fin clips, Striped Bass
scales, and tubes of stomach contents. This might sound like
the stuff of horror movies, but these freezers are vital to
understanding our native California fishes.
In their statement, the scientists laid out the grim picture
that has emerged from thousands of peer-reviewed studies:
Climate change is inflicting extensive harm to aquatic
ecosystems, both in freshwater and the oceans. The degradation
of these ecosystems, which are among the most threatened on
Earth, is accelerating.
Lobbing another hurdle at California’s $16 billion plan to
tunnel underneath the West Coast’s largest estuary,
environmentalists on Thursday sued to freeze public funding for
the megaproject championed by Gov. Gavin Newsom. Led by Sierra
Club and the Center for Biological Diversity, a familiar
coalition of critics claim the cash-strapped state is pursuing
a “blank check” for a project that isn’t fully cooked.
Scientists from several fish and wildlife agencies have
launched a rapid research and response effort for deficiency of
thiamine, or Vitamin B1. This deficiency was recently found to
be increasing juvenile mortality among Chinook salmon in
California’s Central Valley. The magnitude of its effect is not
clear. However, it could be a risk to Chinook stocks, including
endangered winter-run Chinook salmon and the fishery for
fall-run Chinook salmon.
The future of our existing dams, including 2,500 hydroelectric
facilities, is a complicated issue in the age of climate
change. Dams have altered river flows, changed aquatic habitat,
decimated fish populations, and curtailed cultural and treaty
resources for tribes. But does the low-carbon power dams
produce have a role in our energy transition?
The Bureau of Reclamation announces the selection of four
funding award recipients to implement $40 million in salmon
habitat improvement projects along the Sacramento River. The
restoration projects will enhance and improve spawning and
rearing habitat for salmon at approximately 25 different
locations across 132 river miles.
In a review of Feather River fall-run Chinook salmon in
September 2019, I described their status through the 2018 run
and expressed optimism for the 2019 run. My assessment proved
overly optimistic, as the 2019 run numbers came in lower than
expected. The lower-than-expected returns appear to be the
consequence of the 2017 Oroville Dam spillway failures.
Reclamation, working with the Sacramento River Settlement
Contractors and federal and state fish and wildlife agencies,
are implementing fall water operations to benefit salmon
populations in the Sacramento River.
Protecting the health of California’s rivers, estuaries, and
wetlands has been the grandest—and perhaps thorniest—of the
many challenges facing the state’s water managers. The San
Joaquin River watershed, the state’s third largest and an
important water source for irrigating farmland in the San
Joaquin Valley, epitomizes this challenge. Yet California is
making progress here, bringing a glimmer of hope.
Members of local tribes, fishermen and conservationists are
calling on Warren Buffett to undam the Klamath. People across

U.S. Rep. John Garamendi has filed an official objection to a
plan backed by Sonoma County and his House Democratic colleague
Jared Huffman to remove Scott Dam on the Eel River and drain
Lake Pillsbury, a popular recreation spot for nearly a century.
Completely dry riverbeds, record low flows, and diminished fish
populations — that’s what staff and volunteers from a local
environmental nonprofit found when they surveyed tributaries of
the Eel River earlier this month.
Radically transformed from its ancient origin as a vast
tidal-influenced freshwater marsh, the Sacramento-San Joaquin
Delta ecosystem is in constant flux, influenced by factors
within the estuary itself and the massive watersheds that drain
though it into the Pacific Ocean. Lately, however, scientists
say the rate of change has kicked into overdrive…
At least 700 sub-adult and adult winter-run Chinook salmon
(winter Chinook) returned this year to Battle Creek. …
Establishing another self-sustaining population in a second
watershed (in addition to population in Sacramento River), such
as Battle Creek, is a high priority and a major component of
the Central Valley salmonid recovery plan.
Virtual rallies will be held Friday at the utility’s
headquarters in Portland and in Buffett’s hometown of Omaha,

Berkshire Hathaway conglomerate. Berkshire Hathaway Energy is
PacifiCorp’s parent company.
Chinook salmon have become a welcome and familiar sight in
recent years in Putah Creek. Considered a keystone species
across the Pacific Northwest, Chinook salmon hold a special
place in our past and present as a cultural and food resource.
This includes for indigenous peoples of California, such as the
Patwin people, on whose land UC Davis is located.
Congressman John Garamendi, who represents the northern half of
Lake County, on Friday submitted a formal comment to the
Federal Energy Regulatory Commission opposing removal of Scott

future of Potter Valley Project and the lake.
The Bureau of Reclamation plans to temporarily close the Delta
Cross Channel gates at 4 p.m. on Oct. 13. The closure is

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

The Klamath Basin used to be the third most important
salmon-bearing watershed in the Pacific Northwest. Now, only a
fraction of those runs remain. The multiple reasons for their
decline are complex and interconnected, but they all have to do
with how water moves through the system.
In 2012 a team of salmon researchers tried a wild idea: putting
pinky-sized Chinook on a rice field in the Yolo Bypass, a vast
engineered floodplain designed to protect the city of
Sacramento from inundation. … Now, after nearly a decade of
testing fish in fields, a new paper in San Francisco Estuary
and Watershed Science outlines lessons learned as well as next
steps in managing floodplains for salmon.
The Calaveras River Habitat Conservation Plan finalized this

We invite you to watch the event video.
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.
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.
Dams, diversions, and land conversion have substantially
altered California’s rivers and disrupted the processes that

Stakeholders shared their concerns of potential consequences
over a stalled project to remove four hydroelectric dams along
the lower Klamath River during a recent online panel
discussion. Congressman Jared Huffman of California’s Second

Tunnel proponents say they do not expect to operate the tunnel
at capacity, and it would be in use mainly to draw from the
periodic storms that send more water through the Delta out to
San Francisco Bay. But how much would that be? The usual answer
is: we will leave that to the experts.
After months of relative quiet, Newsom’s administration
released a preliminary cost estimate for the scaled-back
project Friday: $15.9 billion for a single tunnel running
beneath the estuary just south of Sacramento. That’s nearly as
much as the old $16.7 billion price tag put on the larger,

North Coast elected officials rang alarm bells Tuesday around
what the region’s congressional representative called a
“slow-walk” on the removal of four Klamath River dams that have
threatened fish populations and led to pollution.
It should not take pleas to Warren Buffett, the billionaire
leader of the Berkshire Hathaway holding company, to save the
wobbling deal to take down four obsolete dams on the Klamath
River. But that is what the state of California and the
Klamath’s Yurok and Karuk tribes are left with…
One survival bottleneck that needs opening for salmon and
steelhead in the Central Valley is predation by non-native
fish. There is a long list of non-native and native predators
from which native fish need protection. The best protection is
to minimize native-nonnative habitat interactions. That can
best come from adequate physical-geographical habitat and
habitat water quality for natives while minimizing non-native
North Coast Congressmember Jared Huffman hosted a forum of the
Water, Oceans and Wildlife Subcommittee he chairs Tuesday

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.
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.
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.
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.
Earlier this year, Reclamation released water from Upper
Klamath Lake — impounded by the Link River Dam in Klamath Falls
— to boost streamflows for coho salmon in the lower Klamath
River. But the Klamath Irrigation District sued, claiming the
bureau does not have an established right from the Oregon Water
Resources Department to use the stored water.
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,
and timing of these surveys make it difficult to compare and
combine the data collected.
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.
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.
With a new water supply delayed by state regulatory agencies
and political infighting, the Monterey Peninsula Water
Management District board has asked the state water board not
to impose Carmel River water reductions due to an inevitable
violation of an approaching river cutback order milestone…
A Marin County Superior Court judge rejected a petition filed
by a group of San Geronimo residents and golfers to halt creek
restoration work in the former San Geronimo Golf Course. The
ten residents and golfers, known as the San Geronimo Heritage
Alliance, filed the lawsuit in July alleging the creek
restoration work is illegal.
Gov. Gavin Newsom has appealed directly to investor Warren
Buffett to support demolishing four hydroelectric dams on a
river along the Oregon-California border to save salmon
populations that have dwindled to almost nothing.
The California Fish Passage Forum brings together public and
private groups and agencies working to remove barriers to fish
passage. We get a quick lesson in the projects and progress of
the Forum in an interview with Chair Bob Pagliuco and

In response to Secretary of the Interior David Bernhardt and
Reclamation Commissioner Brenda Burman’s recent visit with
Klamath Basin ranchers, farmers, tribes and community
officials, Reclamation is launching a new science initiative to
inform Klamath Project operations.
Desperate to complete a historic but complicated dam removal on
the California-Oregon border, Gov. Gavin Newsom has appealed to
one of the world’s wealthiest men to keep the project on track:
financier Warren Buffett. Newsom dispatched a letter to Buffett
and two of his executives Wednesday urging them to support
removal of four hydroelectric dams on the lower Klamath
Species such as salmon, trout and giant catfish are vital not
just to the rivers and lakes in which they breed or feed but to
entire ecosystems. By swimming upstream, they transport
nutrients from the oceans and provide food for many land
animals, including bears, wolves and birds of prey.
New state grants totaling about $8 million will enhance fish
habitat on the Tuolumne River, and better connect west Modesto
residents to the waterway. The grants will continue efforts to
restore spawning areas and floodplains for salmon, trout and
other fish between La Grange and Modesto.
The staff of the Federal Energy Regulatory Commission stated
its support once again for the fishery releases proposed by the
Modesto and Turlock irrigation districts. The action reaffirmed
FERC findings in February 2019 that dismissed pleas from
environmental and sport-fishing groups for much higher flows.

With state and federal administrations fighting in court about
delta water operations—and with a pandemic and election year
both underway—work has slowed on voluntary agreements meant to
avoid severe cuts to northern San Joaquin Valley water
supplies. At issue is the first phase of a State Water
Resources Control Board plan for the Sacramento-San Joaquin
As part of a settlement reached with fishing and environmental
groups, the California State Water Resources Control Board says
it will increase transparency and conduct heightened
evaluations when deciding water quality standards and flow
limits for the state’s critical waterways. …
Environmentalists celebrated the deal as a “landmark
settlement” that stands to boost protections for fish by
improving water quality in the Sacramento River and the San
The country’s largest dam removal project was thrown into
question last week when federal regulators refused to let the
current owner fully transfer the impoundments to a nonprofit to
carry out the demolition.
While it’s fair to say that salmon and steelhead are dying the
death of a thousand cuts in the Eel River, Scott Dam is by far
the deepest and most damaging of these injuries. Dam removal
efforts from Maine to Washington State to here in California
have shown time and again that restoring access to historical
spawning grounds is key to rebounding fish populations.
After four years of review, FERC granted the transfer of the
license for the J.C. Boyle, Copco No. 1, Copco No. 2 and Iron
Gate dams (collectively known as the Lower Klamath Project) to
the Klamath River Renewal Corporation, a nonprofit that would
carry out the dam removal. But it requires PacifiCorp, the
utility that currently operates the dams, to remain on the
In November 2019, a diverse group of nine organizations, known
as the North Yuba Forest Partnership, announced its commitment
to using best available science in planning and implementing
forest restoration at an unprecedented pace and scale within
the North Yuba River watershed. Today, the group released an
online interactive story map highlighting the ecological and
human values within the watershed…
Earlier this year, the California Almond Board released a
report regarding the acreage of almond trees that have reached
bearing age and another with totals including young trees.
These reports paint a stark picture of an unsustainable
industry that threatens the Bay-Delta ecosystem and
California’s salmon fishing jobs.
A five-year battle over plans to log in the remote Gualala
River flood plain has taken a big step up with a powerhouse
environmental group’s declaration to take the case to federal
court, alleging the commercial tree harvest would harm
protected fish, frogs and birds.
The Karuk Tribe is set to hold its World Renewal Ceremonies in
Six Rivers and Klamath national forests from July through late
September. In honor of these long-standing tribal traditions,
outsiders will be prohibited from entering the water or
launching watercraft during the ceremonies, the U.S. Forest
Service has announced in a press release.
The most apparent observation I had after developing the
comments was the substantial amount of work that has been
undertaken in the Sacramento Valley to complete habitat
projects and advance science for Chinook salmon recovery in the
last 5 years.
U.S. Bureau of Reclamation Commissioner Brenda Burman says
she’d like to see more cooperation from California officials as
talks aim to resolve a legal dispute over competing biological
opinions governing the management of their respective water
This legislation will ensure the nation’s water supply is safe
and sustainable. The Water for Tomorrow Act will combine the
water sustainability measures from Sen. Harris’ Water Justice
Act with key measures from the FUTURE Drought Resiliency Act,
led in the House of Representatives by Rep. Jared Huffman
Less than a week before Christmas in 2016, the State Water
Resources Control Board held a single public hearing in our
community. The topic? Draining our community’s water supply and
sending it to the Bay Delta.
For the past two decades, dams have been falling across the
United States in a bid to reverse a legacy of destruction of
fish and their habitat. … But in southwestern Washington, a
local flood control district is going against the flow by
proposing a major new dam on the Chehalis River. … The
Chehalis is a critical salmon stream and the largest river
system fully contained within the state’s boundaries.
While farmers lauded Interior Secretary David Bernhardt and
Bureau of Reclamation Commissioner Brenda Burman’s historic
joint visit to the Klamath Basin on Thursday, area tribes
expressed concern that their perspective on water issues had
not been adequately heard.
The net pen program allows the young fish to leapfrog what
would be a 250-mile river journey to the ocean, where the
salmon would face thousands of water pumps, reverse currents in
the Delta, and the chance of poor water quality and a
procession of predators…
Decades of environmental protection is threatened to be undone
by the recent Trump Administration Executive Order to roll back
regulations from the Clean Water Act to speed up energy
projects. The proceeding EPA rule-making procedures make it
easier for owners of hydroelectric dam projects to bypass state
oversight and environmental accountability. Without legislative
protection, our waterways are under threat.
U.S. Interior Secretary David Bernhardt and Bureau of
Reclamation Commissioner Brenda Burman promised to seek a
resolution to the decades-long water conflicts in the basin
after meeting with growers, local water officials and other
The Fremont Weir Adult Fish Passage Modification Project, which
began modified operations in January of 2019, successfully
allowed thousands of migrating fish to pass between the
Sacramento River and Yolo Bypass in its first year of
The Department of Water Resources (DWR) today awarded $11
million in grants to five projects that will improve the
habitat and chances of survival for native fish species within
the lower San Joaquin River watershed.
On June 24, 2020, the United States District Court for the
Eastern District of California denied the preliminary
injunctive relief requested by a coalition of fishery and
environmental groups regarding the U.S. Bureau of Reclamation’s
operations of Shasta Dam and Reservoir, and related temperature
management actions on the upper Sacramento River.
The St. Helena City Council awarded a $3.2 million contact
Tuesday to an Arcata firm to remove the Upper York Creek Dam.
McCullough Construction will be charged with notching the dam,
restoring the creek’s aquatic habitat, and removing an illegal
barrier to fish passage that the city first agreed to remove in
After an absence of many decades, Chinook salmon swim up the
Guadalupe River in San José most winters. The fish look for
places to lay eggs and often find them. If there’s enough water
left in the dry season, their offspring swim back down the
river in the spring to head out to sea. Surprisingly, given the
generally heated politics regarding fish in California, little
else is known about these salmon.
Hatcheries operated by the California Department of Fish and
Wildlife in the Central Valley just completed the final release
of young Chinook salmon raised this year. More than 20 million
young salmon, called smolts, raised in four state-run
hatcheries were released in various locations throughout the
Sacramento and San Joaquin River systems, the Delta, San Pablo
Bay and into a coastal net pen.
Last week, on the flanks of Mount Lassen, the partnership of
the Western Rivers Conservancy and the Lassen National Forest
completed a project that protects a crucial 1,150-acre
property, and a significant branch of South Fork Antelope
Creek, a rare stronghold for salmon and steelhead in the
Sacramento River system.
The feasibility study refers to removal of Scott Dam as a
foregone conclusion. The reason being salmon and steelhead are
not able to access spawning grounds above the dam. This area is
a small percentage of the overall spawning habitat of the Eel
River watershed. … A fish ladder around Scott Dam makes much
With a global pandemic, a catastrophic economic recession and
record-high unemployment, one would think the state has enough
issues to tackle. But proponents of a state water grab that I
have been fighting since the day I was sworn into office in
2012 disagree. Where others see turmoil and anguish, they see
opportunity. Apparently, they believe in the adage, “Never let
a crisis go to waste.”
American Indian tribes in California’s Klamath Basin praised
Monday’s decision by the United States Supreme Court not to
hear the Klamath Project irrigators’ Fifth Amendment water
rights case, Baley v. United States. By not hearing the case,
the Supreme Court upheld the Klamath Tribes’ treaty water
rights as the most senior water rights in the Klamath Basin.
These water rights are critical to protect the tribes’
fisheries and traditional way of life.
With dry conditions resulting in low flows and threatening the
survival of coho salmon, the State Water Board today sent
notices of water unavailability to110 junior water right
holders in the Scott River basin in Siskiyou County, urging
them to stop diverting.
The Bureau of Reclamation, in partnership with the U.S. Fish
and Wildlife Service, plans to begin construction of the Lower
Clear Creek Floodplain and Stream Channel Restoration Project
Phase 3C on the week of June 22. This project is funded through
the Central Valley Project Improvement Act.
In recognition of the immense opportunity for recovery in Elk
River, CalTrout, the North Coast Regional Water Board, and
several project partners joined together to form the Elk River
Watershed Stewardship Program. The purpose is to engage with
the Elk River community to develop a landowner supported
recovery plan to reduce nuisance flooding, address the severe
sediment impairment, and rehabilitate habitat for native
Over the years we have spent a lot of effort helping fish to
spawn on both sides of the Pacific Ocean, yet occasionally a
project comes along that requires us to do exactly the
opposite. … While this may seem a bit odd, considering recent
efforts to bolster salmon populations in the basin, we were
tasked with preventing spawning in a small area of the
Sacramento River in order to facilitate the construction of a
new bridge at Jelly’s Ferry near Red Bluff, California.
If there’s one certainty in these uncertain times, it’s that
nature is resilient, and one needn’t look further than the San
Joaquin River as an example. For a second year in a row, and
for only the second year in over 65 years, spring-run Chinook
salmon have returned from the ocean to spawn in the river and
bring forth the next generation.
The Fish Friendly Farming Certification Program was designed to
improve water quality and to restore and sustain habitat for
federally-listed threatened species like Chinook salmon and
steelhead trout. In a stunning victory for fish, farming and
our environment, Fish Friendly Farming has already certified 90
percent of all Napa grape vineyards.
CalTrout and our partners have been working extensively with
landowners to figure out ways to leave some of their water
instream for the benefit of salmon. Often this means helping
the landowner improve their on-ranch irrigation efficiency to
decrease the amount of water needed maintain their agricultural
Beginning June 11, the Bureau released flows to help sustain
juvenile salmon, but it plans to provide only 16,000 of the
40,000-acre feet promised in the plan developed with the Yurok
Tribe, fishing groups and irrigators in March. And nearly a
month passed without augmented flows when young salmon were
being infected and dying from disease-causing parasites and 1.5
million hatchery fish were released and ready to pass through
the infection zone.
In order for the Chinook and steelhead to rebound in the Eel
River, there should be at least 26,400 fish returning from the
ocean to spawn annually… Although the Eel salmon population
was larger this year than last, Fish and Wildlife’s June 1
report shows the population fell far below the margin for
species recovery. Only 8,263 made the journey, they wrote.
The Sonoma County Water Agency filed a Temporary Urgency Change
Petition with the State Water Resources Control Board to reduce
Russian River minimum in-stream flows this summer. With the
Ukiah region facing its third driest water year on record, Lake
Mendocino’s water supply is projected to reach critically low
levels due to dry conditions and reduced water transfers from
the Potter Valley Project.
Farmers and ranchers in the Klamath Project are breathing a
sigh of relief after the U.S. Bureau of Reclamation announced
Tuesday it will not further reduce this year’s water allotment,
which is already less than half of demand. … On the other
hand, tribal members that depend on ample salmon runs for their
way of life argue the runs will continue to suffer in warm, low
rivers without enough flow for them to migrate and spawn.
The U.S. Bureau of Reclamation is backpedaling on a plan to
further slash water deliveries to Klamath Basin farmers this
summer, as the agency is reverting to an earlier allocation of
140,000 acre-feet. The bureau in May signaled plans to cut
its allocation to 80,000 acre-feet as part of a three-year
operating plan, initiated under an agreement with the Yurok
Imagine taking a kayak out on the water all day as a full-time
job. Well, that’s exactly what the U.S. Fish and Wildlife
Service employees from the Red Bluff office do for a portion of
the year. The work is critical for surveying Clear Creek for
the presence of steelhead, rainbow trout and late-fall Chinook
salmon nests known as redds.
Recognizing the recovery of Coho salmon in central California’s
streams and rivers as a high priority, the California
Department of Fish and Wildlife is collaborating with NOAA’s
National Marine Fisheries Service, the U.S. Army Corps of
Engineers, and other partner agencies and non-governmental
organizations to develop and implement recovery actions. The
tricky part is that there is no one-size-fits-all approach to
saving the species.
California and federal water regulators are trying to quickly
resolve their legal dispute over competing biological opinions
governing the management of their respective water projects, a
top state official says. The talks are proceeding after Gov.
Gavin Newsom filed suit in February to nullify new federal
opinions that would ease restrictions on surface water for San
Joaquin Valley growers.
By the thousands, they rolled through the Southern Oregon
countryside in tractors, hay trucks, log trucks, pickups and
minivans, their hand-painted signs greeted by supportive
passers-by who agreed with the message of Friday’s “Shut Down
and Fed Up” rally: the water problems that for decades have
plagued the region and its farmers must be resolved.
In a stark reminder that drought has once again taken hold on
the North Coast, Sonoma County is preparing to ask state water
regulators for permission to reduce water levels in the Russian
River this summer to conserve water stored in Lake Mendocino
and ensure minimal late-season flows for fish.
In 2014, the Cleveland National Forest (CNF) initiated an
effort to restore the migratory corridors for fish and other
aquatic species in the San Juan and Santiago Watersheds by
removing the remnants of small (approximately 2 – 15 ft) dams
constructed by Orange County (California) between 1940-70s.
The researchers discovered that salmon survival depends in part
on how long isolated pools spend disconnected from flowing
water: the longer the dry period, the fewer salmon were able to
hang on until the wetter months of fall and winter. And though
fewer salmon overall survived the drought years, the
researchers did find reason for hope. In certain streams and
pools, which the researchers call drought “refuges,” salmon
survival was similar in both drought and non-drought years.
The Klamath Project, a U.S. government-operated waterworks that
steers runoff from the towering Cascades to more than 200,000
acres of potatoes, alfalfa, wheat, onions and other produce on
both sides of the state line, is running low on supplies. The
local water agencies served by the project say they may not
have water to send to farms beyond next month.
A study by the Department of Water Resources (DWR)
investigating the growth rate of juvenile Chinook salmon raised
in the Suisun Marsh area of Solano County was forced to
conclude early due to the ongoing COVID-19 health emergency.
Despite the change of plans, DWR scientists were still able to
gather all pertinent data and are confident the study will
provide useful information regarding how juvenile Chinook
Increased frequency and severity of droughts threatens
California’s endangered salmon population — but pools that
serve as drought refuges could make the difference between life
and death for these vulnerable fish, according to a study by
researchers from UC Berkeley and California Sea Grant…
For Indians, confronting economic uncertainty and food
shortages has been part of life since Europeans arrived in our
lands. … This is why the Yurok Tribe is fighting so hard to
remove Klamath River dams and restore the salmon runs that have
fed our people since the beginning of time.
For decades, sediment buildup in California’s Butano Creek
caused an array of issues for both fish and people. It flooded
roads and local communities, prevented steelhead and coho
salmon from migrating, and contributed to substantial die-offs
of fish. In October 2019, the NOAA Restoration Center and
partners finished a $7 million effort to remove the sediment
and restore the creek.
The Round Valley Indian Tribes, California Trout, Humboldy
County, the Mendocino Inland Water and Power Commission and
Sonoma Water have formed a group called the Two-Basin
Partnership and announced the filing of a feasibility report
with FERC on Wednesday.
The conflict over California water, often compared to a war,
rather resembles a geological process. As along an earthquake
fault, surface spasms come and go. The latest twitch is an
injunction momentarily halting some Trump Administration water
plans. But the underlying pressures are a constant. They never
stop exerting themselves.
A partnership of numerous Northern California agencies intends
to file an initial plan to acquire the Potter Valley project
from the Pacific Gas and Electric Co., multiple sources
confirmed. The coalition will submit a document to the Federal
Energy Regulatory Commission for its consideration. If
approved, the group may be able to form a partnered ownership
of complex water infrastructure dividing the Eel and Russian
A judge issued a preliminary injunction in two lawsuits brought
against the administration by California’s Natural Resources
Agency and Environmental Protection Agency and by a half-dozen
environmental groups. The order bars the U.S. Bureau of
Reclamation until May 31 from going ahead with expanding the
amount of water it pumps from the San Joaquin Delta through the
federal Central Valley Project.
Nicole Kwan is an environmental scientist with DWR’s Division
of Environmental Services. Her work focuses on the aquatic
ecology of the Delta, with emphasis on fish communities and
food web productivity in the Yolo Bypass floodplain. Earlier
this week, Nicole gave a live chat on native fish species as
part of DWR’s “Water Wednesdays”.
For California, the findings could have positive ramifications
for the state’s struggling commercial and recreational salmon
fishing industry. In recent years, state and federal officials
have relied more and more on fish raised in hatcheries that are
hauled downriver via boat or in a truck. The hauling somehow
throws salmon GPS systems out of whack.
Researchers at Scripps Institution of Oceanography at UC San
Diego and the University of Tasmania have found that different
hatchery systems for salmon greatly influence the microbial
communities of the fish, which in turn may influence their
overall health. These findings, published April 17 in the
journal Applied Environmental Microbiology, could have impacts
that determine which hatchery methods produce healthier and
greater volumes of salmon.
During the marathon hearing Thursday, U.S. District Judge Dale
Drozd hinted the environmental groups’ requests for a ruling by
May 11 will be a tall task. Not only is the case complex and
involves dozens of parties, he said the chaos caused by the
pandemic is impeding the court’s ability to move swiftly.
In the spring of 2020, Cal Fish PAC sponsored a webinar
covering the 2017 State of the Salmonids report reviewing the
findings and discussing how to improve resiliency in salmonids
moving forward. The webinar presenters were Patrick Samuel,
California Trout’s Bay Area Program Manager, and Dr. Rob
Lusardi, California Trout-UC Davis Wild and Coldwater Fish
Scientist and aquatic research scientist at UC Davis Center for
Watershed Sciences. Both presenters were co-authors of the
report; Dr. Peter Moyle was the lead author.
At the April meeting of the Central Valley Flood Protection
Board, Board members heard an informational briefing on the
Yolo Bypass Salmonid Habitat Restoration and Fish Passage
Project being planned for the Fremont Weir. Referred to as the
Big Notch, this project will construct a gated notch at Fremont
Weir to create seasonal floodplain habitat for juvenile fish as
well as to improve migration for adult fish.
For us, better science is the only path that can achieve those
two important goals. Unfortunately, as the state completed its
new permitting effort at the end of March, a decade of research
was largely ignored in favor of political objectives that
impose unjustified restrictions on the State Water Project …
Environmental groups in California on April 29 challenged in
court the state Dept. of Water Resources decision not to
include a proposed 40-mile tunnel in its most recent
environmental assessment needed to reauthorize long-term
operation of the State Water Project—a 700-mile system of dams
and aqueducts that moves water from the Sacramento-San Joaquin
Delta to areas in the south.
California water agencies yesterday sued the state over
endangered species protections they claim threaten their
ability to provide water to more than 25 million residents and
thousands of acres of farmland. … At issue is water shipped
from California’s water hub, the Sacramento-San Joaquin River
Delta east of San Francisco, south via the State Water Project,
a massive system of dams, canals and aqueducts.
While salmon counts are low this year, having accurate
information will better inform our conservation efforts.
CalTrout has been using a Sonar system to estimate abundance of
spawning Chinook Salmon, Coho Salmon, and steelhead on the
South Fork Eel River with support from the California
Department of Fish and Wildlife Steelhead Report and
Restoration Card Program.
From the moment he took office, Gov. Gavin Newsom said he
wanted to bring peace to California’s water wars. But now, more
than a year later, most of the warring factions are united
against his plan for governing the Delta. Three of the most
powerful groups in California water sued the state this week
over Newsom’s two-month-old plan for the Sacramento-San Joaquin
Some Klamath Project water users on Sunday and Monday protested
the U.S. Bureau of Reclamation’s use of water at the Link River
Dam, at one point voicing plans to stay near the dam until
Reclamation followed Oregon water law.
The Sites Project Authority plans to recirculate an
environmental document for the proposed Sites Reservoir after
project leaders modified plans recently to right size the
