The State Water Project (SWP) is responsible for bringing
drinking water to 25 million people and provides irrigation for
750,000 acres of farmland. Without it California would never have
become the economic powerhouse it is today.
The nation’s largest state-built water and power development and
conveyance system, the SWP diverts water from the Feather River
to the Central Valley, South Bay Area and Southern California.
Its key feature is the 444-mile long California Aqueduct that can
be viewed from Interstate 5.
The SWP has required the construction of 21 dams and more than
700 miles canals, pipelines and tunnels. To reach Southern
California, the water must be pumped 2,000 feet over the
Tehachapi Mountains; it’s the highest water lift in the world.
Today, about 30 percent of SWP water is used for irrigation,
mostly in the San Joaquin Valley, and about 70 percent is used
for residential, municipal and industrial use, mainly in Southern
California but also in the Bay Area. The SWP was built and is
operated by the California Department of Water Resources.
Has California overshot the runway? … There was a time
when our dams and aqueducts that allowed us to change the
course plotted by nature by not letting water be restricted to
water basins by physical barriers were considered a candidate
for of their wonders of the world. When it came to freeways, we
were the envy of the land. That was then and this is now. The
list of aging infrastructure that needs addressing is
Selection of alternatives to evaluate in an Environmental
Impact Report (EIR) is an important component of public agency
project planning and is typically a required as part of the
environmental review decision-making process. The Department of
Water Resources (DWR) has initiated this process for the
proposed Delta Conveyance Project and is currently preparing a
Draft EIR in compliance with the California Environmental
Quality Act (CEQA).
Known as an engineering expert, water community leader, and
champion of the State Water Project (SWP), former
Department of Water Resources Director William
Gianelli served as DWRs third director from 1967 to 1973
and dedicated more than 30 years to public service in both the
state and federal government. (Gianelli also was one of the
founders of the Water Education Foundation, its second
president and the namesake of the Foundation’s Water Leaders
The Bureau of Reclamation and San Luis & Delta-Mendota Water
Authority finalized the B.F. Sisk Dam Raise and Reservoir
Expansion Project’s Supplemental Environmental Impact
Statement/Environmental Impact Report. This joint proposed
project would create an additional 130,000 acre-feet of storage
space in San Luis Reservoir, producing additional water supply
for 2 million people, over 1 million acres of farmland and
200,000 acres of Pacific Flyway wetlands.
The Delta Conveyance Project is a necessary upgrade to ensure
that our aging 1960-era State Water Project (SWP)
infrastructure will continue to function into the future
… An emerging narrative that we have seen from project
opponents is the false choice between either supporting the
Delta Conveyance Project or supporting more local and regional
projects to develop alternative or expanded water supply
sources. These are not alternatives to each other. We can and
must do both. -Written by Jennifer Pierre, general manager of the State
While deciding the final allocation for growers who gather
their water from the Friant-Kern Canal is months away, things
early on are not looking good. The California Department
of Water Resources announced on Dec. 1 an initial state water
project (SWP) allocation of 10% of requested supply for the
2021 water year. Initial allocations are based on conservative
assumptions regarding hydrology and factors such as reservoir
California’s plans to build a new tunnel to move water from the
northern Delta to the thirsty, populous south of the state
advanced a step Tuesday, when a key partner agreed to help fund
some of the effort.
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.
California’s water managers on Tuesday preliminarily allocated
just 10% of requested water supplies to agencies that together
serve more than 27 million Californians and 750,000 acres of
farmland. The state Department of Water Resources cited the dry
start to the winter rainy season in California’s Mediterranean
climate, in addition to low reservoir levels from last year’s
relatively dry winter. Typically, winter snow supplies around
30% of California’s water as it melts.
The Metropolitan Water District likely won’t pick up the slack
to cover planning costs for the proposed Sacramento-San Joaquin
Delta tunnel. That’s a huge shift from MWD’s “all in” support
of the previous tunnel project.
To adapt to intensifying extremes, federal, state, and local
governments must be proactive in analyzing how climate change
may impact California’s natural resources – as well as people
and property. In a step to toward that goal, the Department of
Water Resources released “Moving to Action”, a call for
essential partnerships, planning, and collaboration with state,
federal, and local agencies.

Join us as we guide you on a virtual journey through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
This virtual experience focuses on the San Joaquin Valley, the southern part of the vast region, which is facing challenges after years of drought, dwindling water supplies, decreasing water quality and farmland conversion for urban growth. The tour gives participants an understanding of the region’s water use and issues as well as the agricultural practices, including new technologies and water-saving measures.
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.
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

changing climate. At their October meeting, commissioners began
the work set out for them in the portfolio…
Getting water through a tunnel under the Sacramento-San Joaquin
Delta would be pricey. So pricey, some Kern County water
districts were looking for an “off-ramp” by potentially selling
their main state water supply out of the county. The request
was shot down on Nov. 6 by the Kern County Water Agency, which
holds the contract for state water on behalf of 13 area water
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.
A team of experts released their findings Monday, concluding
that no urgent repairs are needed right now on the Oroville

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

coalition of critics claim the cash-strapped state is pursuing
a “blank check” for a project that isn’t fully cooked.
The San Joaquin Valley and urban Southern California each face
growing water challenges and a shared interest in ensuring
reliable, affordable water supplies to safeguard their people
and economies. Both regions’ water futures could be more secure
if they take advantage of shared water infrastructure to

Gov. Gavin Newsom, like governors before him, wants to overhaul
how water moves through the delta. He’s proposing a 30-mile
tunnel that would streamline the delivery of water from the
Sacramento River, a bid to halt the ongoing devastation of the
delta’s wetlands and wildlife while ensuring its flows continue
to provide for the rest of the state. The pressures of climate
change on water supplies have only increased the urgency to
act. And the coronavirus pandemic and months of
shelter-in-place orders haven’t slowed the planning. ….The
tunnel, as much as anything, is the very symbol of the state’s
never-ending water wars.
The Department of Water Resources came to the August Delta
Independent Science Board meeting to provide an overview of the
Delta tunnel project including timeline and review process, as
well as some thoughts on the board’s recent letter.
Simply updating costs to this latest estimate ($15.9 billion in
2020 dollars is equivalent to $15 billion in the 2017$) reduces

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

The City of Dos Palos is shutting down water for its residents
for at least three days to treat after its water treatment
plant became clogged with algae. The city says water is
currently being used faster than it can be treated and sent
out, so residents should prepare for water to stop flowing.
A high level of algae in the California Aqueduct has caused
problems over the past several days in Dos Palos. City Manager
Darrell Fonseca explains, “Our siphon intake at the aqueduct
clogged, and that reduced our water supply, and then as we did
receive the water it takes longer to treat at the plant… but
it also meant reduced pressure to a lot of residents, and for a
while, no pressure at all.”

serves 27 million people and irrigates 750,000 acres of
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 agreement pays Antioch $27 million, which guarantees that
they will be able to utilize its 150-year old water rights and
remain in the Delta for the long-term. The $27 million, in
addition to $43 million in State grants and loans, completes
the financing for the $70m Brackish Water Desalination Plant.
In the century-long “us-versus-them” mentality of California
water, a plan released by Gov. Gavin Newsom’s Department of
Water Resources last week achieved something perhaps never
accomplished before in the Golden State’s water industry. It
incited universal scorn.
William Gianelli, the Department of Water Resources’ (DWR’s)
third Director, passed away at the age of 101 in Monterey,
California on March 30. Known for being an engineering expert,
water community leader, and champion of the State Water Project
(SWP), Gianelli dedicated more than 30 years to public service
in both state and federal government.
Today, responding to a global pandemic is every governor’s top
priority. When we emerge from this crisis, Gov. Gavin Newsom
will face a challenge to ensure California’s future economic
and environmental health. In this context, his water policies
will represent critical decisions.
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 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 nature of Butte County’s concerns over Gov. Gavin Newsom’s
scaled back Delta tunnel project was made clear last Tuesday,
when Supervisor Debra Lucero questioned a staffer from the
state Department of Water Resources.
Cindy Messer considers one of her greatest professional
accomplishments also the toughest experience in her 23-year
career. Messer was sworn in as chief deputy director of the
California Department of Water Resources the day after the
Oroville Dam crisis began in February 2017… But within
months, her boss retired, and she became acting interim
director for the recovery phase.
Besides reviewing and making final determinations on submitted
plans that show how local agencies will manage their
groundwater basins for long-term sustainability, DWR staff

The Department of Water Resources (DWR) is soliciting public
comment on the scope of environmental review for a revised
Delta tunnel project despite prior findings of independent
technical experts that a key project proposal is “impractical,”
stating that it “does not recommend” further study.
Because the State and Federal water managers coordinate
operations of the State Water Project and Central Valley
Project, the State Water Contractors argue that dumping the
biological opinions governing those operations and restarting
the process would create “uncertainty in water supply
availability, potentially affecting the [State Water
Contractor] members’ water supplies from the SWP.”
Over the past month, DWR has been holding scoping meetings in
the Delta and select locations throughout the state. At
meetings in Walnut Grove, Stockton, Clarksburg and Brentwood, a
diverse group of farmers, fishermen, elected officials,
climate/social justice activists, economists and engineers came
out in force to oppose what is often referred to as the
If our state wants to remain economically competitive, it must
re-engineer the troubled estuary that serves as the hub of
California’s elaborate water-delivery system — the
Sacramento-San Joaquin River Delta. The best and most viable
way to do this is via the single Delta tunnel project proposed
by Gov. Gavin Newsom…
The Sacramento splittail is a lovely, silvery-white fish that
lives primarily in Suisun Marsh, the north Delta and other
parts of the San Francisco Estuary (SFE; Moyle et al. 2004).
The name comes from its unusual tail, in which the upper lobe
is larger than the lower lobe. It is a distinctive endemic
species that for decades has fascinated those of us who work in
The message was loud and clear for state water officials at a
public meeting Monday evening in Redding: Don’t send any more
water south through a proposed Delta tunnel project. A group of
more than 100 Native Americans rallied on the lawn of the
Redding Civic Auditorium before they marched into a scoping
meeting held inside the Redding Sheraton Hotel across the
As Delta smelt continue to decline throughout the
Sacramento-San Joaquin Delta, novel approaches are being

Plumas supervisors reminded the state that the best way to
protect natural resources is by not depleting them, especially
when other natural resources are available, such as the Pacific

The Santa Monica City Council approved a water self-sufficiency
plan Tuesday that will double the price of water and wastewater
removal by 2024. The rate increases will finance about $42
million in infrastructure projects that will allow Santa Monica
to stop importing water from the Metropolitan Water District of
Southern California by 2023.
As I watch the way Governor Gavin Newsom is handling water
policy, I have two thoughts. First, the governor is on a track
that seems driven by adherence to some of Governor Jerry
Brown’s worst water policies. And, second, he’s not getting

For decades, California’s coastal aquifers have been plagued by
invading seawater, turning pristine wells into salty ruins. But
the state’s coastal water agencies now plan to get more
aggressive in holding back the invasion by injecting millions
of gallons of treated sewage and other purified wastewater deep
The problem with the theory is that a delta tunnel (state
officials like to call it a “conveyance”) would yield all those
benefits only if it were one piece of a larger complex of
projects, policies and agreements to keep water flowing through
the overly depleted San Joaquin River and limit the volume and
timing of water diversions. And those other parts of the puzzle
simply aren’t there.
On Friday, the California Department of Water Resources (DWR)
announced an increase in 2020 State Water Project (SWP)
allocations to 15 percent of requested supplies, up from the
year’s initial 10 percent allocation announced on December 2.
The Newsom administration appears to be a house divided on
water, as competing interests pull it in opposite directions.

Response to Wednesday’s action by the California Department of
Water Resources to initiate an environmental impact report for
a tunnel project in the Sacramento-San Joaquin River Delta was
not popular with the San Joaquin County Board of Supervisors.
As Gov. Gavin Newsom and his administration attempt to
establish a comprehensive and cohesive water policy for the
state, officials are seeking public input on the draft water
resilience portfolio released earlier this month. The document
was issued in response to Newsom’s April 2019 executive order
directing his administration to inventory and assess a wide
range of water-related challenges and solutions.
Even though water districts and cities throughout the San
Bernardino Valley rely on local rainfall and mountain runoff
for about 70 percent of their water supply, local supplies are
not enough. The region relies on Sierra snowmelt from Northern
California to meet the remaining 30 percent.
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
While Newsom has been forced to address climate change on many
fronts during the past year – think wildfires, blackouts and
automobile standards – the state’s myriad water challenges must
remain a priority. Our state’s water system is decades old and
needs to be re-envisioned for a new era.
California’s governor has restarted a project to build a giant,
underground tunnel that would pump billions of gallons of water
from the Sacramento-San Joaquin Delta to the southern part of
the state. Gov. Gavin Newsom’s administration on Wednesday
issued a Notice of Preparation for the project, which is the
first step in the state’s lengthy environmental review process.
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…
The factors causing the decline of many fish and fisheries in
the upper San Francisco Estuary have made their management
controversial, usually because of the correlation of declines
with increased water exports from the Delta and upstream of the
Delta… To address this problem better, the California Fish
and Game Commission is developing new policies for managing
Delta fish and fisheries, with a special focus on striped bass.
The Henry J. Mills Water Treatment Plant will be out of service
for nine days and the Western Municipal Water District will not
be able to import water, forcing the agency to rely on its
reserves, officials said. The work began Friday, Jan. 10, and
Metropolitan Water District of Southern California crews will
be fixing and modifying the facility until Jan. 19, according
to the agency.
South Coast Water District will gear up to undertake its next
milestone for desalination: financing the project. On Thursday,
Jan. 9, after press time, General Manager Rick Shintaku

analysis for the proposed desalination project.
Who can deny the value of potable water to every living thing
in this city, this county, this state? Four million residential
and industrial customers in 43 cities in the Los Angeles, San
Gabriel and San Fernando Basins are dependent on multiple water
sources – groundwater pumped from below them, by aqueduct from
the Colorado River, the Sierra Nevada snowpack, Mono Lake, the
Owens Valley and recycled from wastewater treatment plants.
Farm organizations welcomed a new water planning document from
state agencies while they analyzed the document’s proposed
strategies. Titled the California Water Resilience Portfolio

in a way that works for people, the environment and the
Consistent with the science developed over the last three
decades, the Newsom administration is pursuing comprehensive,
watershed-wide solutions that address the numerous factors that
limit the abundance of native fish in the Delta. These types of
solutions are the ones that are most likely to achieve the
state’s co-equal goals of the 2009 Delta Reform Act…
Governor Newsom’s administration recently released a draft
Water Resilience Portfolio plan… This plan also emphasizes
diverse relatively precise policy initiatives for state
agencies, often in support of local and regional water
problem-solving and with some aspirations to bring state
agencies together. It is a good read, clearly reflecting
intense and diverse discussions over several months.
As of Thursday, the statewide Sierra Nevada snowpack — a major
source of California’s water supply — stood at 90% of its
historical average. That’s the highest total in early January
in four years, when it came in at 101% on Jan. 2, 2016.

information is critical to the water managers who allocate
California’s natural water resources to regions downstream.
The governor’s apparent willingness to play into the hands of
monied, agri-business players at the expense of the health of
the Sacramento-San Joaquin River Delta remains the biggest
mystery of his short tenure. It also threatens to trash his
reputation as a strong protector of California’s environment.
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
to Central Valley farms and urban users in the Bay Area and
The Feather River Recovery Alliance has filed a motion to

safety concerns at the Oroville Dam.
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.
The California Department of Water Resources announced an
initial State Water Project allocation of 10% for the 2020
calendar year. According to a DWR announcement, the initial
allocation is based on several factors, such as conservative
dry hydrology, reservoir storage, and releases necessary to
meet water supply and environmental demands.
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.
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
Despite increased maintenance of Oroville Dam since the
spillway fell apart in February 2017, members of the
community-led Oroville Dam Ad Hoc Group have expressed concern
about the age and wear of mechanics within the spillway’s main
gates, citing similar failures on dams of the same era.
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…

The latest public relations effort cost California water
ratepayers $29,000 to produce an eight-page color advertising
insert that ran in recent days in six Sacramento Valley

In October, the Trump Administration released politically
manipulated “biological opinions” under the federal Endangered
Species Act that dramatically weaken protections for the
Bay-Delta, endangered fish species and commercially valuable
salmon runs. … However, in an uncharacteristically subdued
response, the Newsom Administration stated that it “will
evaluate the federal government’s proposal, but will continue
to push back if it does not reflect our values.”

The glaring light of extinction of the Delta smelt reveals
decades of treachery and deceit by corporate agribusiness,
metropolitan water districts, politicians and their
collaborators in the resource agencies charged by law to
protect wildlife species from extinction. The moral squalor
that has permitted this crisis is contemptible.
