Anadromous fish are freshwater fish that migrate to sea then
return to spawn in freshwater. In California, anadromous
fish include coho salmon, Chinook salmon and steelhead. Those in
the Central Valley have experienced significant declines from
Of particular importance is the Chinook salmon as 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, migratory obstacles created by water projects,
unfavorable ocean conditions, pollution and introduced predator
The Anadromous Fish Restoration Program (AFRP), a part of the
Central Valley Project Improvement Act, aims to double the
natural production of fish that migrate between fresh water and
salt water. The goal is to boost the numbers of anadromous fish
to at least twice the levels attained during the period of
Since 1995, AFRP has implemented more than 195 projects through
funding by Congressional appropriations and a surcharge imposed
on Central Valley Project water and power contractors.
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.
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.
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…
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.
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.
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
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 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.
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.
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.
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.
The California Environmental Quality Act scoping period

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.
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 …
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.
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.
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
project proposed for Colusa and Glenn counties. The reservoir
capacity will be reduced from 1.8 million acre feet capacity to
from 1.3 to 1.5 million acre feet.
On the campaign trail in 2016, President Trump swung into
California’s agricultural hub and vowed to deliver more water
to the drought-ridden state’s farmers. … Three years into his
administration, Trump is now opening the floodgate to deliver
on that promise, setting up the most intense water war between
the federal government and California in the state’s history.
At the 2020 California Water Law Symposium, a panel discussed
the project. Seated on the panel was Richard Roos-Collins, a
principal with the Water and Power Law Group and General
Counsel for the Klamath River Renewal Corporation; Paul
Weiland, lawyer for Siskiyou County; and Mike Belchik, Senior
Fisheries Biologist with the Yurok Tribe.
As expected, irrigators in the Klamath Project are getting less
water than they will likely need this summer thanks to a
combination of dry weather and more water being kept in-stream
to protect threatened coho salmon.
When the Water Forum Agreement was officially signed 20 years
ago, the occasion marked an unprecedented show of regional
cooperation. For years, interests representing business, the
environment, water suppliers and others had sparred over the
water needs of people vs. the environment of the lower American
The Bureau of Reclamation, in coordination with PacifiCorp,
plans to increase flows below Iron Gate Dam to reduce the risk
of disease for coho salmon in the Klamath River. Starting
Wednesday, April 22, flows below Iron Gate Dam will increase
from approximately 1,325 cubic feet per second up to 6,000 cfs.
Today, the Bureau of Reclamation updated the water supply
allocation for Friant Division Central Valley Project contracts
for the 2020 contract year. The Friant Division provides water
for 15,000 family farms and several cities in the Central
Valley. … Given the current hydrologic conditions,
Reclamation is increasing the Class 1 allocation from 40% to
55%; Class 2 remains at 0%.
California Attorney General Xavier Becerra filed a motion
Tuesday evening seeking to stop implementation of new Federal
environmental guidelines aimed at boosting water supplies for
the Central Valley and Southern California from the
Sacramento-San Joaquin Delta.
Counts of Chinook salmon in the Eel River were lower during the
2019 – 2020 ocean runs than any previous count conducted by the
Eel River Recovery Project since the organization began
tracking in 2012, according a new report, with estimates the
entire Chinook salmon run below 10,000 fish.
Now, just as the first Earth Day in 1970 gave U.S. policymakers
a chance to chart a fresh course for conservation, this year’s
50th anniversary offers lawmakers an opportunity to act on a
growing body of evidence that free-flowing, well-protected
rivers serve the greater public good.
Two separate letters sent to President Donald Trump and members
of Congress highlight the importance of providing support for
enhancing water management, particularly in light of the
tumultuous conditions created by COVID-19.
Federal and regional operators of Southern California’s
Twitchell Dam lost their bid to dismiss claims the dam causes
unlawful killing of endangered steelhead trout, but they won’t
face an emergency injunction restricting their operations, a
federal judge ruled Friday.
The case was filed in late 2001, the year there was an
announcement that no water would be available for Klamath
Project irrigation from Upper Klamath Lake. The plaintiffs
claim that if the water is taken under the Endangered Species
Act, the fifth amendment of the U.S. Constitution requires
payment of compensation for the water right, a form of
property, that has been taken.
The whole San Francisco Bay ecosystem—that enormous estuary
with its maze of bays, rich delta, and associated rivers and
streams—is in the midst of an ecological calamity. Decades of
dam building and water extraction to quench the thirst of
California’s growing population and the needs of its mighty
agriculture industry have starved the state’s waterways, as
well as the bay itself, of crucial freshwater supplies. As a
result, the entire estuary is under enormous stress.
For the last four years, our team at UC Davis has been
conducting scientific studies on reintroduced spring-run
Chinook salmon in the San Joaquin River and we wanted to take a
minute to share some of what we’ve learned. Plus, everyone
loves a good comeback story right?
On March 13, 2020, water users in the Klamath Reclamation
Project (Project) petitioned the United States Supreme Court to
review the Federal Circuit Court of Appeals’ decision in Baley,
et al. v. United States, et al. (Baley). The decision denied
the water users’ takings claims for the 2001 Project water
shutoff on water law grounds.
Yolo Basin Foundation’s Board of Directors announced this week
that Chelsea Martinez has been named the Foundation’s new
executive director. … Martinez joined the Foundation in 2017
as the Community Outreach & Volunteer Coordinator and has grown
and sustained the Foundation’s volunteer base to over 200
volunteers as well as helped to increase community involvement
in its programs.
Voluntary agreements in California have been touted as an
innovative and flexible way to improve environmental conditions
in the Sacramento-San Joaquin Delta and the rivers that feed
it. … Yet, no one said it would be easy getting interest
groups with sometimes sharply different views – and some, such
as farmers, with livelihoods heavily dependent on water — to
reach consensus on how to address the water quality and habitat
needs of the Delta watershed.
The Klamath River Renewal Corporation’s plans to remove four
dams on the Klamath River in the US has taken a major step
forward with the issuance of key documents from the California
State Water Board. The plan – the largest dam removal project
in the US – would re-open 360 miles of the Klamath River and
its tributaries to salmon.
A rare, wild green sturgeon was found on the San Joaquin River
upriver from the confluence of the Merced this past weekend by
U.S. Bureau of Reclamation crews checking salmon traps at Hills
Ferry. The discovery caused some excitement as this endangered
fish had not been seen that far up the San Joaquin in many
years, according to National Marine Fisheries Service staff.
Ted Grantham is a Cooperative Extension Specialist at UC
Berkeley and the CalTrout Ecosystem Fellow with the Public
Policy Institute of California. … In this presentation, Dr.
Grantham discussed environmental flows and the policy context
in California in which environmental flows are managed and how
that has evolved over time.
How critical are Sacramento Valley floodplains for a vibrant
fishery? A California Fish and Game Bulletin from 1930 gives us
a clue. The report documents the Sacramento River commercial
salmon catch declining from 6 million pounds in 1918 to less
than 1 million pounds by 1927.
The state recently got a new permit for water delivery
operations from its wildlife agency. In the past, that kind of
authority came from adhering to federal rules. Now, with a
dispute between the state and federal government over water
management and endangered species act protections, the state
issued its own permit. Critics of the state’s move say they
plan to file lawsuits.
Several Congressional leaders sent a letter to Governor Gavin
Newsom expressing disappointment in the decision to issue an
incidental take permit for long-term operations of the State
Water Project. … The letter was signed by Representatives
Kevin McCarthy, Devin Nunes, Ken Calvert, Tom McClintock, Doug
LaMalfa, and Paul Cook.
The largest dam removal project in U.S. history came one step
closer to fruition this week, as California issued permits for
breaching the four dams on the Klamath River. The State Water
Resources Control Board issued a Clean Water Act certification
and environmental assessment for the proposal to remove three
dams in Northern California and one in southern Oregon.
Big Chico Creek is an ideal stream to monitor fish populations
for a number of reasons. For one, the creek’s flow patterns,
especially in the area we surveyed, have hardly been altered
from their natural state, as there are no dams or large
diversions. As such, data from Big Chico Creek can provide
insights on how populations of threatened fish fare under
Southern Resident killer whales have long pursued the biggest
and most nourishing Chinook salmon from coastal Pacific waters.
Chinook salmon fishing is also a mainstay of the West Coast
economy, generating nearly $72 million in income last year. Is
there room for both? The answer is yes, with safeguards.
Lower Battle Creek in Tehama County is one of the 19 waterways
to be part of the Wildlife Conservation Board $24.3 million
grant program set to help enhance flows in streams throughout
California. … The project will dedicate water rights to
instream flow in the lower 7.3 miles of Battle Creek to restore
dwindling Chinook salmon and steelhead
At the 2020 California Water Law Symposium, a panel discussed
the history of the project. Speaking on the panel was Chief
Caleen Sisk with the Winnemem Wintu Tribe, Doug Obegi with the
Natural Resources Defense Council, and Darcie Houck who is
currently General Counsel with California Energy Commission,
but formerly represented the Winnemem Wintu Tribe when she was
in private practice.
The State Water Board today issued key documents that move the
Klamath River Renewal Corporation significantly closer to
removing four dams and re-opening 360 miles of the Klamath
River and its tributaries to imperiled salmon.
Taking advantage of recently approved rules, the federal
government is quickly following through on President Donald
Trump’s promise to quiet environmentalists and “open up the
water” to California farmers. … The pumps in the south of the
Sacramento-San Joaquin River Delta aren’t just whizzing during
what will likely end up being classified a “critically dry”
hydrological year, they are churning — and killing — endangered
salmon during a critical migration period.
Unprecedented efforts by leaders at the state and national
level have led to the kind of cooperation that will provide
valuable benefits to water users and the environment. I know
because that’s what we’ve been doing in the Sacramento Valley
for many years. The kinds of success we’ve achieved can be
replicated in other parts of the state.
A new set of water regulations aimed at protecting California’s
native fish came down from the state earlier this week to near
universal condemnation from both agricultural and environmental
water folks. The regulations are contained in a 143-page
“incidental take permit” issued by the state Department of Fish
and Wildlife …
The U.S. Bureau of Reclamation has issued a new three-year
operating plan for the Klamath River, dedicating more water for
endangered salmon while avoiding a “worst case scenario” for
farmers and ranchers. In exchange, a local tribe and fishing
groups agreed to suspend a lawsuit filed against the agency in
The rules take the form of a state Fish and Wildlife Department
permit that will govern State Water Project deliveries from the
Sacramento-San Joaquin Delta… But the permit does not
explicitly control the U.S. Bureau of Reclamation’s Central
Valley Project, which exports Delta water to San Joaquin Valley
farms. That means the two big government pumping operations
will likely adhere to different standards — possibly allowing
the federal project to boost deliveries at the expense of the

The Hoopa Valley Tribe applauded Fresno County Superior Court’s
refusal to validate a proposed contract between Westlands Water
District and the Bureau of Reclamation. … The contract would
have allocated up to 1,150,000 acre-feet of water annually to
Westlands, most of which would be imported from the Trinity
River, which has sustained the Hupa people since time
The second-largest river in California has sustained Native
American tribes with plentiful salmon for millennia, provided
upstream farmers with irrigation water for generations and
served as a haven for retirees who built dream homes along its
banks. With so many competing demands, the Klamath River has
come to symbolize a larger struggle over the increasingly
precious water resources of the U.S. West…
Winter-flooded rice fields already provide essential habitat
for migratory birds, but could they also provide benefits to
help the state’s salmon populations? Scientists at the
University of California, Davis, are finalizing their fieldwork
on an experiment to find out what management practices farmers
might adopt in their fields to maximize fish survival.
The COVID-19 virus outbreak is affecting us all, whether we
live in a big city or rural Siskiyou County. The economy is
grinding to a halt and governments are planning a massive
response to keep money flowing to small businesses and
employees – the lifeblood of the entire economy. It is through
this lens that I encourage Klamath Basin residents to
view Klamath River Renewal Corp.’s dam removal and river
restoration project as an economic bright spot.
During a week full of COVID-19-related uncertainty, a pair of
new lawsuits are a reminder of one constant: disputes over
Klamath Basin water. This past week, PacifiCorp and Klamath
Water Users Association each filed petitions for review of
Total Maximum Daily Loads (TMDLs) for temperature in the Upper
Klamath and Lost River subbasins.
Coho salmon are getting a boost from the California Department
of Fish and Wildlife (CDFW) strategic plan to prioritize salmon
restoration and habitat improvement projects in coastal
watersheds from Santa Cruz to Mendocino counties. In most of
these watersheds, coho salmon are in severe decline or locally
extinct due to human alterations to land and water resources.
Two lawsuits challenging the Trump administration’s
authorization of plans to increase water pumping from the
Sacramento and San Joaquin watersheds will be moved from the
Northern District of California to the Eastern District of
California, a federal judge ruled.
In February 2017, damage to the Oroville Dam’s spillways
prompted the evacuation of more than 180,000 people living
downstream along the Feather River. The raging muddy waters
also triggered an emergency decision to relocate millions of
young salmon from the Feather River Hatchery to the Thermalito
Annex Hatchery to be raised and held until river water
conditions improved. … Those fish survived and were later
released to the wild – helping fuel a record class salmon
harvest in the ocean two years later.
Vallee and his team are here to maintain an array of
hydrophones used to track migrating native fish. The work is
part of a multi-agency effort to provide more timely and
detailed information about the movements of salmon, steelhead,
and sturgeon in the Central Valley. Deploying hundreds of
listening stations across the watershed, the program lets
scientists follow thousands of tagged fish as they navigate
from hatcheries and headwater streams toward the Pacific Ocean.
The return of rainbow trout to Calaveras Creek marks a

The case, titled Baley v. United States, was filed 19 years ago
when the U.S. Bureau of Reclamation re-allocated Klamath River
irrigation water to threatened and endangered species. A
favorable outcome would mean upwards of $30 million
collectively in compensation for irrigators named in the case.
As discussed below, in the case of west coast salmon, the
scientific evidence is clear that the replacement assumption
has proven faulty as the total abundance of salmon declined at
the same time the propagation and release of hatchery salmon
The new rules allow the federal Central Valley Project to kill
100 percent of baby winter run Chinook salmon below Shasta Dam
for three years running. Chinook salmon live for three
years, so authorizing the Bureau of Reclamation to kill every
endangered winter run for three years amounts to an extinction
plan for this species.
The 2020 ocean abundance projection for Sacramento River fall
Chinook, the driver of West Coast salmon fisheries, is
estimated at 473,200 adult salmon, higher than the 2019
forecast. However, the Klamath River fall Chinook abundance
forecast of 186,600 adult salmon is lower than the 2019
forecast and will likely result in reduced fishing opportunity
in the areas north of Pt. Arena…
In a Feb. 28 filing, the Klamath River Renewal Corporation,
formed to shepherd the removal of four hydroelectric dams from
the Klamath River in Northeern California and Southern Oregon,
submitted key budget information to the Federal Energy
Regulatory Commission. … This filing is another concrete step
toward implementing the amended Klamath Hydroelectric
Settlement Agreement (KHSA), removing the dams and restoring a
free-flowing Klamath River, KRRC officials said.
If you live in Southern California or Silicon Valley, you might
be surprised to learn that your local water district (a member
agency of the State Water Contractors) is siding with the Trump
Administration, and defending Trump’s plan to increase water
diversions, despite the widespread acknowledgement that this
plan is likely to drive salmon and Delta smelt extinct.
On Thursday, the U.S. Bureau of Reclamation delivered its own
salvo to the Newsom administration – it was pushing forward
pre-construction work on raising Shasta Dam. … A push to

A Simon Fraser University-led research team has found
significant evidence that human activity in estuaries is
impacting juvenile Pacific and Atlantic salmon. The team’s
review of 167 peer-reviewed studies (from an initial search of

including the effects of flood-protecting tidal gates,
pollution and habitat modification.
A day after President Trump visited the Central Valley to
celebrate a boost in water for California farms, state
officials sued to block the additional water deliveries.
Attorney General Xavier Becerra, in a lawsuit filed Thursday,
maintains that new federal rules designed to increase pumping
from the Sacramento San Joaquin River Delta fail to protect
salmon and other endangered fish in the delta estuary.
Following a promising 2018 fall Chinook salmon season on the
Klamath that saw the run size trending upwards, the 2019
returns fell significantly short of expectations. Looking at
the numbers presented in the PFMC “Review of 2019 Ocean Salmon
Fisheries” document, it’s likely we’ll have some severe
restrictions both in the ocean and in the Klamath and Trinity
rivers in 2020.
Gov. Gavin Newsom, in a pre-emptive strike against President
Donald Trump, said Wednesday he plans to sue Trump’s
administration to block a controversial plan to increase water
deliveries to the San Joaquin Valley. Newsom’s office said he
“will file legal action in the coming days … to protect
highly imperiled fish species close to extinction.”
In the latest update, the cost of implementing the voluntary
agreements has soared by over $4 billion to a whopping $5.3
billion. Governor Newsom failed to mention the enormous and
growing costs in his oped praising the voluntary agreement
During President Trump’s visit to California this week, the
commander in chief who campaigned on a pledge of shipping more
water to Central Valley farms plans to stop in Bakersfield to
boast about a promise kept. … But what confounds some who are
worried that Trump’s water plan could undermine the environment
is how little the state has done to stop Washington.
Hoisting the spoils of victories in California’s hard-fought
water wars, President Donald Trump is directing more of the
state’s precious water to wealthy farmers and other agriculture
interests when he visits their Republican Central Valley
It’s time for Gov. Gavin Newsom to own up on water policy. He
can either play nice with a roughshod plan from President Trump
to divert crucial water flows or craft his own blueprint that
balances both wildlife and California’s economy.
Though the process leading to removal of the Klamath Dams
continues to march forward, numerous citizens in Siskiyou
County have continued fighting to keep the dams in place. Many

to their survival.”
The Ventura City Council announced Monday that it may request a
six-month extension from the court for the thousands who were
sent legal notices or served with a court summons in the case.
… The litigation dates back to 2014 when Santa Barbara
Channelkeeper filed a lawsuit alleging the city of Ventura
was taking too much water from the Ventura River,
hurting habitat for steelhead trout and other wildlife.
The governor’s newest proposal signals Newsom may be softening
his fight against Trump, but opening another battle. Newsom may
have traded a court fight with Trump for a legal battle with
the very environmentalists the Democratic administration has
seen as allies.
From an ecologist’s perspective, river habitat and species
population sizes and life histories were shaped by unimpaired
flow patterns (including volume and natural variability) across
seasons and years. Science from across the world, other regions
in the US, and right here in California suggests that we can
take some of that flow for other uses, but must preserve
adequate volume and natural patterns of variation if we want
native species to survive.
To inform our conservation work on the Eel, CalTrout has teamed
up with partners on this new project – The Adult Salmonid Sonar
Monitoring Program – to tally the annual spawning run of
Chinook salmon, coho salmon, and steelhead on the South Fork
Eel River with a Sound Metrics Dual Frequency Identification
One of the major questions fish biologists are often asked is
“how much water do fish need?” In 2016, a group of scientists
from California Trout, UC Davis, UC Berkeley, The Nature
Conservancy, Utah State University and the Southern California
Coastal Water Research Project, with funding in partnership
from the State Water Board, began to delve into this question
Current research shows 11 of the remaining 21 anadromous
salmonids in California are at critical risk of extinction in
the next 50 years under present trends. Estuaries are
especially important to the survival of juvenile salmonids
given their important role, helping to increase the number of
adult salmonids that survive to adulthood and return to spawn.
The multi-year, multi-agency effort to transform the lower
landscape of the Carmel River into a natural floodplain took a
massive step forward Jan. 28 when the Monterey County Board of
Supervisors voted unanimously to approve the project’s final
environmental impact report.
Ken W. Davis, an aquatic biologist and wildlife photographer,
prefers the more isolated ambiance of nature’s waterways – and
the quiet of his lab – and has been studying aquatic
invertebrates for 30 years. Much of his work now is dedicated
to the health of Putah Creek, and its tributaries, and has an
ultimate goal of seeing an ecosystem that includes elements
that existed prior to the construction of the Monticello Dam in
Nearly a year after construction was halted a second time at a
large resort project at the north end of Healdsburg when
water-quality regulators allegedly found millions of gallons of
sediment-filled stormwater running off into Russian River
tributaries, the agency announced it is pursuing a $4.9 million
fine against the developer.
The City Council passed a resolution to make a formal request
of the Monterey Peninsula Water Management District that it
allocate additional water to develop affordable housing. …
Most of the Peninsula is under a moratorium for additional
water hook-ups following the cease-and-desist order instituted
in 1995 when the State Water Resources Control Board ordered
California American Water to stop over-pumping the Carmel
At a panel discussion hosted by California Natural Resources
Secretary Wade Crowfoot, the panelists discussed how by
spreading out and slowing down water across the landscape can
provide multiple benefits year-round by allowing farmers to
cultivate the land during the spring and summer, and provide
habitat for fish and wildlife in the fall and winter months.
Since July, the Department of Water Resources (DWR) and State
Water Contractors have engaged in fruitless negotiations over
how to pay for a single-tunnel Delta Conveyance Facility. On
December 23, right before the holidays, DWR made their 6th
proposal to the State WaterContractors with a major shift in
The main focus of the program are the barriers to fish passage
for salmon from Friant Dam to the ocean and back again. There
are three key barriers: the East Side Bypass Control Structure
which is in the flood bypass; Sack Dam, which is the intake for
Arroyo Canal for Henry Miller irrigation system; and Mendota
Dam which controls Mendota Pool. The program also needs to
ensure enough habitat for the fish when they return to complete
their life cycle,
Santa Barbara County and the U.S. Army Corps of Engineers have
issued notices of violation to Southern California Edison for
its dumping of debris and rocks into Mission Creek near the
Inspiration Point hiking trail. … Mission Creek is Santa
Barbara’s largest creek, flowing from the hills of Mission
Canyon through the heart of downtown and to the Westside. It is
home to steelhead trout among other wildlife.
The Sonoma Index-Tribune recently published a couple of
articles about beavers and otters in Sonoma Creek… It’s a
good sign, not just because it’s nice to know that Sonoma
Valley’s main waterway is actually clean enough to support
wildlife, but also because beavers can actually improve life
for other critters, including my favorite, rainbow trout.
Now Trump’s team is set to impose new environmentally damaging
Bay-Delta water diversion and pumping rules. … These new
rules would wipe out salmon and other wildlife by allowing
wholesale siphoning of water from Northern California rivers to

The number of Coho salmon in Northern California’s Shasta and
Scott rivers in 2019 was too low to sustain a viable
population. That’s according to a just-released report from the
California Department of Fish and Wildlife. The most recent

The territory encompassed by the 5th State Senate District has
been a battleground for California’s complex water politics. So
it’s not surprising the two Democrats and three Republicans
running to succeed Sen. Cathleen Galgiani, D-Stockton, who is
terming out this year, might tap dance around questions
regarding Tuolumne and Stanislaus river flows and water quality
in the Sacramento-San Joaquin Delta.
In the early days, these pot farms were small and scattered.
But in recent years the industry has intensified. A wave of
newcomers planted larger farms, using greenhouses and
artificial lights to extend the growing season and yield up to
three marijuana crops in a single year. The cannabis boom has
polluted waters with fertilizers, fuels and pesticides,
triggered erosion that buries the rocky habitats where salmon
and trout spawn and grow, and drained streams of water in the
The Central Valley fall-run population is a fraction of its
historic size and continues to face challenges as a result of
factors that range from loss of habitat and changing ocean
conditions to pressures from predation and harvest in
freshwater and the ocean. Even under good environmental
conditions, fall-run Chinook face a slew of challenges over the
course of their lives.
At the December meeting of the Delta Stewardship Council,
Caitlin Sweeney, Director of the San Francisco Estuary
Partnership, briefed the Council on the 2019 update to the
State of the Estuary report. She began with some background on
With virtually no public notice, state officials quietly gave
away a significant portion of Southern California’s water
supply to farmers in the Central Valley as part of a deal with
the Trump administration in December 2018. One year later, it
remains unclear why the California Department of Water
Resources signed the agreement…
West Marin ranchers and a local conservation group are teaming
up to plan habitat restoration projects along Walker Creek to
restore the once bountiful, but now diminished, runs of coho
salmon and steelhead trout. The California Department of Fish

Biologists, heavy equipment operators, government agencies, and
non-profits all working together. Hopefully, they’re major
steps toward restoring the endangered chinook salmon winter run
in the Sacramento River.
Every year since 2014, I have petitioned the State Water
Resources Control Board to end the widespread practice of
irrigation, especially of cattle pastures, outside the legal
irrigation season. So far, however, State Water Board staff
have not taken effective action to end the illegal water use
and the resulting degradation of Scott River stream
What started as a plan for a fun trip down the Sacramento Rver
turned into a storytelling mission for Mitch Dion and his
friend Tom Bartels, who set out to interview farmers,
politicians and others who were impacted by the river.
Since 2015, the state’s commercial fishermen have reported
nearly record-low catches. Fish hatcheries produce most of the
salmon caught in California today, and with much of their
inland habitat badly degraded, truly wild salmon are scarce.
But a small circle of biologists and fishermen believe they can
revive California’s legendary Chinook to something resembling
its historic glory.
These changes will be substantial, multi-faceted, and often
rapid. Some changes will be irreversible. Many changes are
inevitable. Some will say today’s Delta is doomed. It will be
important for California to develop a scientific program that
can help guide difficult policy and management discussions and
decision-making through these challenges.
Federal agency representatives on Friday night kept the
conversation going with U.S. Sen. Jeff Merkley about continued
efforts to save two Klamath Basin sucker species from
extinction. … Merkley has delivered $23.5 million to the
Basin since 2013 to find a way toward a solution. He recently
secured $11 million for sucker recovery efforts, including $5.1
million for the Klamath River.
Over the next few weeks, all owners of any real property that

The fish’s growth rates peaked at average water temperatures of
61.8 degrees fahrenheit, and what Lusardi calls an “unheard of”
maximum weekly temperature of 70. So, how did the cold-water
fish survive the warmer temperatures? There was enough food —
aquatic invertebrates like freshwater shrimp or mayflies — in
the water to compensate for the rise in temperature.
The new guidelines call for diverting more water from the
Sacramento-San Joaquin River Delta to agribusiness and urban
areas further south. Barbara Barrigan-Parilla with the group

to sue over the new federal guidelines, that hasn’t happened
Large numbers of fall-run Chinook salmon have returned to the
Mokelumne River in Clements this fall despite challenging
salmon fishing on the river and adjacent sloughs this season. A
total of over 12,658 salmon have gone over Woodbridge Dam in

House Natural Resources Chairman Raúl M. Grijalva of Arizona
wants his committee to give him subpoena authority for multiple
possible investigations, but California Democrat Jim Costa may
vote against that as the panel considers whether Interior
Secretary David Bernhardt improperly influenced a decision to
send more water to his district.
The manipulation of rivers in California is jeopardizing the
resilience of native Chinook salmon. It compresses their
migration timing to the point that they crowd their habitats.
They may miss the best window for entering the ocean and
growing into adults, new research shows. The good news is that
even small steps to improve their access to habitat and restore
natural flows could boost their survival.
On Monday, the Monterey Peninsula Water Management District
board is set to consider approving $1.24 million on consultants

Lower Butano Creek had been clogged by a mile-and-a-half long
plug of sediment where the stream once flowed through the marsh
to meet the ocean. … In June, the resource conservation
district, in partnership with California State Parks and the
National Oceanic and Atmospheric Administration, embarked on a
$7 million restoration project to remove the sediment dam
blocking Butano Creek.
Salmon are swimming back into the Lagunitas Creek watershed.
Not only is that a natural phenomena, but it is a sign that
hard work at restoring habitat and promoting greater public
awareness are paying off.
Votes of support by local jurisdictions bring the project one
step closer to reality. Reality is a costly giant tunnel that
would divert Sacramento River water bound for the
Sacramento/San Joaquin Delta and transport the water directly

In the United States, many of the structures that were once
engineering marvels are nearing the age most humans decide to
retire. Despite steadily increased budgets for dam repair and
maintenance, over the past four decades more than a 1,000 have
failed … Although some dams are having critical maintenance
done, states and private entities are also coming up with a
different solution: take them down. California, once a
bastion of dam building, took down 35 dams just last year,
making it the leader in dam removals in 2018.
An all-out attempt to save the historic coho salmon runs

The Supreme Court today will weigh in a closed-door conference
whether to take up a dispute over states’ role in water

After a dry fall, the first storms of the winter kicked off the
annual migration of coho salmon from the Pacific Ocean to the
streams where they spawn. Over 10 inches of rain fell on Lake
Lagunitas last week… Streamflows are now high enough to allow
endangered central California coast coho to migrate.
We face an important opportunity to finally put the seemingly
permanent conflicts that have defined water and environmental
management in California behind us, but not if we let it drift
away. This new era of opportunity springs from a common
recognition that our ways of doing business have failed to meet
the needs of all interests.
In her address to the State of the Estuary conference, Felicia
Marcus spoke about the connections of the Delta to all
Californians and the importance of working together and more
broadly to solve the challenging problems before us.
Rather than physically move water hundreds of kilometers across
earthquake country between Northern California and San
Bernardino, the plan involves reallocating water virtually,
just as you would electronically transfer funds from one bank
account to another. Once the Chino Basin Program is
operational, in times of drought the southern region can draw
water from the new reserve instead of from the State Water
Project… That will mean water impounded by Oroville Dam can
be released into the Feather River, benefitting endangered
While local tribes celebrated a federal appellate court ruling
last month upholding their senior water rights on the Klamath
River, a trio of threats facing the Trinity River combine to
paint a foreboding picture for local salmon populations.
The fracas over California’s scarce water supplies will tumble
into a San Francisco courtroom after a lawsuit was filed this
week claiming the federal government’s plan to loosen previous
restrictions on water deliveries to farmers is a blueprint for
wiping out fish.
Most of the Trump administration’s lawsuit challenging
California water management rules affecting the San Francisco
Bay Area has been paused indefinitely so a state court can
consider parallel claims the government filed there. Both suits

the “water quality control plan” covering the Bay Area and the
Sacramento-San Joaquin Delta Estuary.
The complaint says the Trump administration did not fully
consider scientific facts or logic, and arbitrarily concluded
that the projects would not have a damaging effect on
endangered fish species, including salmon and steelhead. …
The projects at issue divert water from the Sacramento and San
Joaquin Rivers to the San Francisco Bay/Sacramento-San Joaquin
River Delta, primarily for agricultural and municipal uses.
CalTrout has identified Scott Dam, which impounds Eel River
water in Lake Pillsbury, as one of five aging dams it considers
“ripe for removal,” especially in the wake of PG&E’s
license surrender. There is, however, a potential middle course
backed by Friends of the Eel River, a Eureka-based nonprofit
that has long called for the dam’s removal.
The work, which started in August, focused on restoring natural
habitat for the fish by removing boulder walls called ripraps
along the creek banks and placing large pieces of trees into
the creek. The riprap walls … channeled the water into a
swift current during the rainy season, which scoured away
salmon eggs and salmon fry that were attempting to survive the
long year-and-a-half in freshwater.
California’s water policy community continues to be embroiled
on how best to manage what remains of California’s native
aquatic ecosystems, particularly for the Sacramento-San Joaquin
Delta and its tributaries. One aspect of this controversy is

Gov. Gavin Newsom’s administration has given environmentalists
much of what they presumably want as it released a 610-page
draft Delta environmental report recently that calls for $1.5
billion in habitat restoration among other environmental
projects. … But as much as they cheered the lawsuit
announcement, environmentalists were aghast at the report
because the state plan will allow some additional water for
Reliable water is critical to every aspect of the economy as
more than 40 percent of the nation’s fruits, nuts and
vegetables are grown in the Central Valley, much of that using
water from the Central Valley Project (CVP) and its largest
reservoir — Shasta Lake.
There’s a war over the future of water on the Monterey
Peninsula and it’s taking place in the board chambers of half a
dozen state and local government entities. It’s also taking
place on social media and in the press.
Central Valley agriculture faces a looming existential water
crisis from the interlocking problems of drought, climate
change, and falling underground water tables. Yet the potential
answer to this problem is incredibly simple and only a lack of
political will may defeat it. The solution is to send south to
California the abundant waters of the Columbia River.
Lots of stories circulate about the unethical actions of
Bernhardt and Gov. Newsom’s reluctance to fight Trump on water
— stories about Bernhardt’s effort to get rid of scientists who
concluded the new Trump Water Plan jeopardizes endangered
species in the Delta. Then there’s his work to give Westlands a
permanent water contract to irrigate poisoned selenium-ridden
lands… What’s not being covered: the impact these projects
will have on the Trinity and Klamath Rivers, and Newsom’s
reluctance to stop them.
Exactly what the Potter Valley Project will look like in the
future is not set in stone. The partnership is committed to
identifying solutions that meet the needs of the communities
and wildlife affected by the project’s operations.
Researchers in Canada and the U.S. investigated potential
reductions in streamflow, caused by groundwater pumping for
cannabis irrigation, in the Navarro River in Mendocino County,
California… Reporting in the journal Environmental Research

observed making use of it.
California officials sent mixed signals Thursday when they said
they will sue to block a Trump administration rollback of
endangered species protections for imperiled fish — while also
proposing new water operations that mimic parts of the Trump
plan. The state moves reflect political pressure the Newsom
administration has been under as it confronts one of
California’s most intractable environmental conflicts — the
battle over the ailing Sacramento-San Joaquin Delta…
Westlands Water District, Fresno-based agricultural water
district, is set to convert its temporary, renewable water
service agreements with the Federal government into a permanent

Initially, federal scientists wrote a draft report that found
increasing water exports would harm California’s native salmon
population, a species already imperiled. Those scientists were
reassigned. Now, the Trump administration and David Bernhardt
have released a new proposal, and guess what? Westlands can
grab even more water from the Bay-Delta.
On Thursday (11/21) we may find out whether the California
Department of Water Resources (DWR) is proposing operations of

DWR will be aligning with the Trump Administration.
In Napa County, adjacent to Sonoma and the source of perhaps
the most expensive cabernet sauvignon outside of Bordeaux,
