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.
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.
The Department of Water Resources urged people to avoid
physical contact with the water at San Luis Reservoir in Merced
County until further notice due to blue-green algae. Boating is
allowed, but swimming and other water-contact recreation and
sporting activities are not considered safe under the warning
advisory due to potential adverse health effects.
At the May meeting of the California Water Commission,
Assistant Executive Officer Jennifer Ruffolo presented the
draft of the 2019 Annual Review of the Construction and
Operation of the State Water Project for the Commission’s
consideration and possible approval. Once approved, Commission
staff will distribute the review to DWR and the Legislature.
As part of an effort to modernize Pyramid Dam located in Los
Angeles County, the Department of Water Resources (DWR)
recently completed assessments for the dam’s gated and
emergency spillways. The Pyramid Dam Modernization Program is
now entering the investigations phase, which includes
structural and hydraulic analyses for the gated spillway and
erodibility analysis for the emergency spillway.
Two factors are believed to weigh heavily on the Delta smelt’s
fate. The biggest is the reduction in fresh water in the Delta
since water started flowing southward via the California
Aqueduct in the 1960s. … The other threat to Delta smelt are
larger fish particularly non-native striped bass and largemouth
bass that were introduced to the Delta by man.
Governor Newsom’s May Revisions to the 2020-2021 state budget
reflect … a $54.3 billion budget deficit and propose $18
billion in cuts to state expenditures. … This blog post
provides a short summary of the proposed budget changes and
their impacts on California water management.
The metric identifies the amount of carbon dioxide per
acre-foot of water transported by the State Water Project.
Water districts receiving water from the SWP can use this
metric to understand the emissions of their water supply
chains, and customers can better understand the ‘carbon
intensity’ of the water they purchase.
The State Water Project now expects to deliver 20 percent of
requested supplies in 2020 thanks to above-average
precipitation in May, the California Department of Water
Resources announced. An initial allocation of 10 percent was
announced in December and increased to 15 percent in January.
Today’s announcement will likely be the final allocation update
Most people in California receive some of their drinking water
supply from the State Water Project (SWP). The SWP also
supplies water to over 10% of California’s irrigated
agriculture. The SWP and its service area span much of
California, delivering water to 29 wholesale contractors

A water budget is an accounting of the rates of the inflows,
outflows, and changes in water storage in a specific area;
however, as simple as that might sound, developing an accurate
water budget can be a difficult and challenging endeavor. To
address this problem, the Department of Water Resources has
developed a water budget handbook…
Members of a committee designed to ensure Delta communities and
tribal groups have their say in a proposed, life-changing
tunnel project have been told to work through the coronavirus
pandemic—or be left out of the process. Some committee members
also claim that state officials misrepresented that fact to one
of the most important commissions monitoring their efforts.
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.
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.
Work to restore a damaged 9-foot diameter water pipeline in

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 …
The reduced-use directive was put in place after a contractor
punctured the 9-foot-diameter Santa Ana Valley Pipeline on
Thursday. The water flow in the line has been stopped while
repairs take place, and the moves by the districts were to help
ensure reserves are not depleted.
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

The Metropolitan Water District of Southern California on
Tuesday voted to sue the state of California over a permit one
state agency granted to another at the end of March. The permit
is related to operations of the State Water Project, which
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.
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 …
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.
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,

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

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 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.
The Newsom administration appears to be a house divided on

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.
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…

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.
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

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.

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 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.
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

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

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,

In a move that would boost water deliveries to San Joaquin
Valley agriculture and Southern California cities, federal
fishery agencies are weakening decade-old endangered species
protections for some of the state’s most imperiled native fish
The Delta smelt is such a small and translucent fish that it
often disappears from view when it swims in the turbid waters
of its home in the Sacramento-San Joaquin Delta. However, it’s
also been disappearing from the Delta entirely.
The state Department of Water Resources and Butte County
announced the settlement Tuesday, more than two years after
spillways at the Oroville Dam crumbled and fell away during
heavy rains. The repairs resulted in heavy truck traffic that
damaged Butte County roads. Butte County sued in August 2018.
Explore the Sacramento River and its tributaries through a scenic landscape as we learn about the issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of California’s water and feed into two major projects: the State Water Project and the federal Central Valley Project. Tour participants will get an on-site update of Oroville Dam spillway repairs.
Just how far will Gov. Gavin Newsom go in his high-profile
fight with the Trump administration over environmental
protections? The next few months will provide an answer, as
Newsom is forced to take a stand on Trump rollbacks in a
long-contested battleground — the Northern California Delta
that helps supply more than half the state’s population with
drinking water and fills irrigation canals on millions of acres
Santa Maria and several other Central Coast Water Authority
members are planning to claim an additional 12,214 acre-feet of
state water that was set aside decades ago. The move — which
would be funded by issuing a $42 million bond — would increase
Santa Maria’s annual right to state water from 17,820 to over
27,000 acre-feet each year.
The proposed water rates include a fixed meter charge per month
and a variable consumption charge per unit of water. The city
says most single family residences will see about a $15
increase in January of 2020. … The last rate increase was
approved by the city council five years ago, but he says a lot
has changed since then.
The southern part of California’s Central Coast from San Luis
Obispo County to Ventura County, home to about 1.5 million
people, is blessed with a pleasing Mediterranean climate and a
picturesque terrain. Yet while its unique geography abounds in
beauty, the area perpetually struggles with drought.
The southern part of California’s Central Coast from San Luis Obispo County to Ventura County, home to about 1.5 million people, is blessed with a pleasing Mediterranean climate and a picturesque terrain. Yet while its unique geography abounds in beauty, the area perpetually struggles with drought.
Indeed, while the rest of California breathed a sigh of relief with the return of wet weather after the severe drought of 2012–2016, places such as Santa Barbara still grappled with dry conditions.
At the August meeting of the California Water Commission, Karla
Nemeth, Director of the Department of Water Resources (DWR),
spoke to the commissioners about the Department’s strategic
plan and the work underway on the Delta conveyance project,
which she noted nests into the strategic plan as a key feature
of what needs to be done to modernize the State Water Project.
Newsom has said he won’t approve Senate President Pro Tem Toni
Atkins’ bid for a legal backstop against environmental
rollbacks by the Trump administration. And Washington is poised
to reduce protections for endangered fish species in the
state’s largest watersheds. The result may be the heightened
regulatory uncertainty that opponents of the bill said they
hoped to avoid…
Whatever satisfaction might be gained by telling the president
to pound sand is nowhere near as important as protecting the
water supply of Modesto and thousands of farmers depending on
the Stanislaus, Tuolumne and Merced rivers.
Newsom saw SB 1 as a mortal threat to something he’s been
supporting since shortly before he took office: a tentative
truce in California’s longstanding water wars. The truce
revolves around the flow of water in and out of the Delta from
California’s most important river systems, the Sacramento and
Today, the California Department of Water Resources began
assessment work on Pyramid Dam’s spillways in Los Angeles
County as part of a statewide effort to reduce seismic and
hydrologic risk to State Water Project facilities spanning 705
miles throughout California.
We applaud Gov. Gavin Newsom’s efforts in leading discussions
with the United States Department of the Interior, public water
agencies and environmental groups to craft voluntary agreements
that will restore the ecological health of the Sacramento-San

Recently, the Sacramento Press Club hosted a panel discussion
on the future of California water featuring Secretary Wade
Crowfoot, Metropolitan General Manager Jeff Kightlinger, and
State Water Contractors General Manager Jennifer Pierre.
While there’s no court action yet, the Water Authority is
gearing up for what in the water world amounts to a rare change
in relationship status. After decades buying water from the
Water Authority, Rainbow and Fallbrook want a divorce.
The Department of Water Resources is continuing to work on the
environmental planning and permitting to modernize State Water
Project infrastructure in the Delta. This effort is consistent
with Governor Newsom’s direction and support for a
single-tunnel project to ensure a climate resilient water
Here we provide an updated account of Suisun Marsh fishes to

upper San Francisco Estuary in general…and why we continue to
be enthusiastic about working there.
The City Council is split on how much to raise water rates over
the next five years to fund projects that will wean Santa
Monica off of imported water. … Bi-monthly water and
wastewater bills for single-family homes would increase by $23
on average under the lower rate structure and $36 under the
higher rate structure.
Computer models are in use every day, all around us. Car makers
use them to test the safety of vehicles, meteorologists use
them to predict the weather, and marketing professionals use
them to analyze connections between people and products. Rooted
in math and science and computer programming, models are also
an important tool in water management…
The State Water Project helped make Kern County the number one
agricultural county in the nation and ensures Bakersfield
always has a clean, high quality supply of drinking water while
protecting our region against drought. The State Water Project
reflects our past generation’s drive to make California the
great state it is today.
Ventura started paying for its right to state water in 1971. On
Monday night, policymakers took the biggest step yet to being
able to access it. The Ventura City Council voted 6-0 to
approve a study certifying no major environmental impacts would
result from building the 7-mile pipeline near Camarillo. The
action means the city’s next move is hiring a consultant to
draft the interconnection’s final design.
San Joaquin County has filed a lawsuit in Superior Court asking
the state Department of Water Resources to abide by local
drilling permit requirements to protect wildlife and water
quality in accordance with California law.
Opponents of the twin tunnels breathed a collective sigh of
relief in April when Gov. Gavin Newsom put a formal end to the
California WaterFix project, but that action also called for
the assessment of a single-tunnel project in the Delta. The
first major step in that direction took place last week when
the Department of Water Resources (DWR) initiated a series of
negotiations with public water agencies that participate in the
State Water Project (SWP)…
While it may not be obvious to some, sustainable groundwater
management is inherently connected to the long-term survival of
the Delta. Not only does the state’s most significant
groundwater use occur in regions that also rely upon water from
the Delta watershed, reduced reliance on the Delta and improved
regional self-reliance are central to many of the goals
outlined in the Delta Stewardship Council’s Delta Plan.
Are you planning a road trip this summer? Consider taking a
detour to one of the many beaches along the California State

natural beauty, and fun ways to spend your vacation.
An earthquake doesn’t have to happen in your neighborhood or
city, or even your region, for it to have an impact, especially
on Southern California’s water supply. According to UCLA
Professor Jon Stewart, the three main water systems that bring
water to Southern California each cross the San Andreas Fault
at least once.
For many years, federal “biological opinions” for delta smelt
and winter run chinook salmon have dictated restrictions on
operations of the pumps, reservoirs and canals of the federal
Central Valley Project and State Water Project… Informed by a
decade of science and on-the-ground experience with what we
know has not worked, long-awaited new federal biological
opinions are finally nearing completion.
The latest update of the California Water Plan was released
this past week. You may not have heard the news. You may not
even know there is a California Water Plan. And that’s just
fine, because it doesn’t mean a darn thing.
The Department of Water Resources (DWR) urged people to avoid
physical contact with the water at San Luis Reservoir in Merced
County until further notice and avoid eating fish from the lake
due to the presence of blue-green algae. DWR increased the
advisory from warning to danger after detecting an increased
amount of microcystins.
Secretary of Natural Resources Wade Crowfoot discussed the
Governor’s water resilience portfolio and reiterated the Newsom
administration’s support for modernized conveyance in the
Delta. That was followed by a robust discussion that included
Delta conveyance, water storage, emerging contaminants and
PFAS, among other things.
Many Delta problems are worsening. Climate change is raising
sea levels and temperatures, making floods and droughts more
extreme and will likely further alter the mix of species. State
legislation to end overdrafting of groundwater will increase
demands for water from the Delta from farmers in the San
Joaquin Valley struggling (mostly in vain) to find replacement
We estimate that nearly 20%—or 840,000 acres—of irrigated
cropland in the valley has no access to surface water. … With
groundwater cuts looming and no other water supply to fall back
on, groundwater-only areas are on the front line of the effort
to bring basins into balance.
It is a telling illustration of the precarious state of United
States dams that the near-collapse in February 2017 of Oroville
Dam, the nation’s tallest, occurred in California, considered
one of the nation’s leading states in dam safety management.
San Diego faces a hidden earthquake threat — to its water
supply. A quake, even one so far away that nobody in San Diego
feels it, could force mandatory water-use restrictions. That’s
because most of San Diego’s water comes from hundreds of miles
away through threads of metal and concrete that connect us to
distant rivers and reservoirs.
Industry veteran Gloria Gray took the helm at the Metropolitan
Water District of Southern California. In this interview, Gray
shares how she plans to steer the largest water supplier in the

The California Water Commission held the first listening
session at its June meeting with a panel of water management
experts offering their perspectives on what a climate-resilient
water portfolio might look like.
The standoff between Sacramento County and the California
Department of Water Resources over the Delta’s future took a
twist in June, moving from quiet canals and pear orchards along
the river to a courtroom in the central city. That’s where
county officials were granted a temporary restraining order
against DWR to halt what they call risky and illegal drilling.
On the last Saturday in June, a road in Butte County was
opened. That in itself isn’t anything unusual. Roads are opened
and closed regularly around here. But it was the significance
of this road that makes it a remarkable occurrence. It was the
road over Oroville Dam.
In 2016 California’s rainy season kicked off right on schedule,
at the beginning of October. … By February there was so much
water filling Northern California’s rivers that Oroville Dam,
the tallest in the country, threatened to break after its
spillway and emergency spillways both failed. It was a wake-up
call. In just a few months California had gone from
five-year-drought to deluge, ending up with the second wettest
year on record for the state.
A civilian watchdog panel called has upon several agencies to
clear up muddy communications to help end spats among members
receiving and distributing water as they move toward another
25-year deal for Lake Cachuma water.
Oroville Dam is officially back open to the public two years
after it was forced to close due to the failure of the dam’s
main and emergency spillways. People can now walk and bike the
more than one-mile-long road across the dam crest. Public
vehicles will still not be allowed.
The facility would serve two main purposes. In addition to
weaning Camarillo customers off imported water from Calleguas
Municipal Water District, it would also help filter out the
everincreasing amount of salt found in the plumes of water
beneath much of the eastern half of the city.
This tour travels deep into California’s water hub and traverses the Sacramento-San Joaquin Delta, a 720,000-acre network of islands and canals that supports the state’s water system and is California’s most crucial water and ecological resource. The tour will make its way to San Francisco Bay and includes a ferry ride.
In order to address the impacts of climate change on the

Delta smelt are poor swimmers. When they have to swim against
voluminous outflows, they struggle. They also lack endurance
for distance and swimming against currents. This was the result
of the taxpayer-funded swim performance test conducted more
than 20 years ago. Why is this important?
Governor Newsom recently called for a state portfolio of
actions to manage water under rapidly changing climate and
other conditions. This post reviews the state of water
portfolio planning in California today.
The Kern County Water Agency supports the state’s “reset” to a
one-tunnel approach because it is more cost effective and still
prepares California’s water system for earthquakes and climate
change while protecting the Delta’s fish and communities.
There are more concerns over lake levels in Oroville as Butte
County leaders take initiative to explore alternative options
for safety measures. The Department of Water Resources (DWR), a
leg of the State Water Project, manages the Oroville Dam. On
Wednesday, DWR officials remained adamant in saying they have
no plans to release water from the Oroville Dam spillway.
As part of efforts by Metropolitan Water District of Southern
California (MWD) to assess its 2014-2016 turf replacement
program during the California drought, we evaluated how yards

County. We also evaluated trends in participation across
On our August Edge of Drought Tour, we’re venturing into the
Santa Barbara area to learn about the water challenges and the
steps being taken to boost supplies. The region’s local surface
and groundwater supplies are limited, and its hydrologic
recovery often has lagged behind much of the state despite the
recent lifting of a drought emergency declaration following
this winter’s storms.
Well, apparently we’re all about to die again. The internet
says so. And while the internet often says we’re all about to
die, and we don’t, for some reason people still unquestionably
believe the next scare to come down the information highway. So
it is with the latest local scare, involving the Oroville Dam
Mission Springs Water District alleged that Desert Water
Agency, which also provides water to more than 100,000 Palm
Springs and Cathedral City residents, made a board decision
that violated a previous settlement between the two agencies.
… Last month, the issue over groundwater management in Desert
Hot Springs picked up steam when a study group
formed by Mission Springs published a 16-page report that
lambasted Desert Water Agency’s actions…
When asked about his priorities, California’s recently
appointed Natural Resources Secretary quickly rattles off a
range of topics: climate change; strengthening water supply
resilience; and building water capacity for communities,
agriculture, and the environment, among them.
Like everyone else in Santa Clara Valley who uses wells,
farmers will see their groundwater production charges go up 6.8
percent this year. But unlike the others, they’ll continue to
receive substantial subsidies. In approving the increased
charges for well users, the Santa Clara Valley Water District
board left intact for at least two years the current structure
that allows farmers to pay only 6 percent of the amount
residents and businesses pay.
The big conflicts are deeply interconnected and appear to be
reaching their climactic phases. How they are resolved over the
next few years will write an entirely new chapter in
California’s water history, changing priorities and perhaps
shifting water from agriculture to urban users and
In reality, the WaterFix could not increase water exports while
protecting the Delta ecosystem. That’s because California’s
snow and rainfall are highly variable, making it unlikely that
existing supplies can meet increasing water demands reliably
into the future. Plus, the science demonstrates that San
Francisco Bay’s fish and wildlife need more water, not less, to
flow from the Central Valley to the Bay.
Because of the wet weather this winter, the district is
proposing to lower its Stage Two Drought Condition to a Stage
One Drought Condition, which would lift many mandatory drought
The Los Angeles Department of Water and Power has turned two
big lakes into a monster battery capable of storing enough
energy to power tens of thousands of homes. It involves using
the excess wind and solar power L.A.’s renewable energy sites
produce during the day to pump water from Castaic Lake uphill
7.5 miles to Pyramid Lake.
The California Energy Commission is offering the city of San
Luis Obispo a $3 million loan to build a 261-kilowatt solar
photovoltaic system as well as a 264-kilowatt hydroelectric
generation system — both located at the city water treatment
plant on Stenner Creek Road behind Cal Poly. By generating its
own power at the treatment facility, SLO could earn savings of
$266,863 annually compared to its current power bill.
Gov. Gavin Newsom’s call on Monday for a new comprehensive
water plan for California looks like a smart timeout on one of
the state’s trickiest and most intractable battlefronts. As
with many political hot potatoes, there is no way to make
everyone happy when it comes to water management, because the
sides have mutually exclusive goals…
At first blush, Gov. Gavin Newsom’s latest action on water
seems fanciful and naive. But it has logic and conceivably
could work. Newsom wants to reexamine practically everything
the state has been working on — meaning what former Gov. Jerry
Brown was doing — and piece together a grand plan for
California’s future that can draw the support of longtime water
Santa Maria residents are being asked by the city to cut down
on the amount of water softeners used through the end of the
year. City officials say the city will begin delivering
better-quality municipal water with a lower mineral content.
… Using water softeners in addition to this new municipal
water could be damaging to pipes and fixtures.
Every day during the winter and spring, pumping operations for
the state’s two largest water projects in the Sacramento-San

regulations via the Endangered Species Act. These same
regulations provide no similar guidance on what flows are
appropriate through the Delta and out to San Francisco Bay
during this critical time in the lifespan of species such as
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
Gov. Gavin Newsom’s administration is taking unprecedented
steps to combat President Donald Trump’s efforts to ship more
water to his agricultural allies in the San Joaquin Valley.
Saying Trump’s water plans are scientifically indefensible and
would violate the state’s Endangered Species Act, the state
Department of Water Resources on Friday began drawing up new
regulations governing how water is pumped from the
Sacramento-San Joaquin Delta to the southern half of the state.
