Constructed long ago by federal effort to help create farmland,
the Central Valley Project is one of the biggest water and
transport systems in the entire world.
In years of normal precipitation, it stores and distributes about
20 percent of the state’s developed water through its massive
system of reservoirs and canals.Water is transported 450 miles
from Lake Shasta in Northern California to Bakersfield in the
southern San Joaquin Valley.
Along the way, the CVP encompasses 18 dams and reservoirs with a
combined storage capacity of 11 million acre-feet, 11 power
plants and three fish hatcheries. As part of this, the Delta
Mendota Canal and Friant Dam on the San Joaquin River deliver
water to farms in the Central Valley.
California water regulators will be delivering the bare minimum
of water supplies to the state’s municipalities via the State
Water Project, the Department of Water Resources announced to
water users on Wednesday. For Valley farmers, who hoped for an
ounce of good news related to water supplies heading into 2022,
they will see a zero-percent water allocation from state water
agencies to start the year. It’s the first time in the history
of the State Water Project for officials to kick off a water
year with a zero initial allocation.
The California Department of Water Resources (DWR) amended a
federal permit application last week to change to the preferred
tunnel route for the proposed Delta Conveyance Project (DCP), a
move that has Delta advocates questioning DWR’s long-term plans
for the South Delta. The agency said the move was necessary to
align the federal permit application – known as a Section 404
and filed with the U.S. Army Corps of Engineers (USACE) – and a
draft environmental impact report that is currently being
prepared by DWR.
At the November meeting of Metropolitan’s Bay-Delta Committee,
Bay-Delta Initiatives Manager Steven Arakawa briefed the
committee members on recent communications from elected
officials and others regarding the operations of the federal
and state water projects and the voluntary agreements.
California water agencies that serve 27 million residents and
750,000 acres of farmland won’t get any of the water they’ve
requested from the state heading into 2022 other than what’s
needed for critical health and safety, state officials
announced Wednesday. It’s the earliest date the Department of
Water Resources has issued a 0% water allocation, a milestone
that reflects the dire conditions in California as drought
continues to grip the nation’s most populous state and
reservoirs sit at historically low levels.
The state Department of Water Resources has designated $100
million for repairs on four major canals that flow through the
[San Joaquin] Valley. In an announcement made Monday, the
agency said that the goal is to restore the canals’ carrying
capacity. Portions of the California Aqueduct, San Luis Canal,
Delta-Mendota Canal, and Friant-Kern Canal can’t convey as much
water as they used to because of land subsidence.
A coordinated effort between the Biden and Newsom
administrations to drop two-year-old environmental rules
governing water deliveries to the Central Valley and Southern
California reached a new benchmark two days before
Thanksgiving. In a flurry of pre-holiday filings, Federal
officials, in consultation with Newsom administration
officials, requested that a Fresno-based Federal judge adopt a
hastily-arranged plan to govern water pumping in the
Sacramento-San Joaquin Delta.
As planning and environmental review efforts continue to
support the Department of Water Resources’ (DWR) determination
of whether a single tunnel option to modernize Delta conveyance
should be approved, an important component of the environmental
review process is to assess environmental resource impacts
within the Sacramento-San Joaquin Delta’s (Delta) estuary.
I have reported every year for over a decade on the results of
the California Department of Fish and Wildlife’s Fall Midwater
Trawl Survey. For the past three years, no Delta smelt,
once the most abundant fish in the entire Sacramento-San
Joaquin River Delta, have been found in this survey. None have
been found in the first two months of the four-month survey
this year either.
Congressman David Valadao (R-21) sent a letter signed by
several other congress members requesting federal and state
emergency declarations in the wake of the drought and recent
storms in California. Valadao, with Rep. Kevin McCarthy (R-23)
and other Republican representatives sent a letter to President
Biden and Governor Newsom requesting that all limitations on
Delta pump operations be lifted to allow water from the recent
storm to be used to help the many farms that have been
devastated by the drought.
This weekend’s atmospheric river brought record-breaking
amounts of rain to drought-plagued California. But they didn’t
give the state’s water supply much of a boost, data shows. The
state Department of Water Resources compared the amount of
water in select reservoirs across the state as of midnight Oct.
25 to the capacity of each reservoir and to historic levels for
the same date. The data shows that, even after all of Sunday
and Monday’s rainfall, many of California’s largest reservoirs
are still holding less water than the historic level for this
time of year.
This tour guided participants on a virtual exploration of the Sacramento River and its tributaries and 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.
This tour guided participants on a virtual journey deep into California’s most crucial water and ecological resource – the Sacramento-San Joaquin Delta. The 720,000-acre network of islands and canals support the state’s two major water systems – the State Water Project and the Central Valley Project. The Delta and the connecting San Francisco Bay form the largest freshwater tidal estuary of its kind on the West coast.
A government agency that controls much of California’s water
supply released its initial allocation for 2021, and the
numbers reinforced fears that the state is falling into another
drought. The U.S. Bureau of Reclamation said Tuesday that most
of the water agencies that rely on the Central Valley Project
will get just 5% of their contract supply, a dismally low
number. Although the figure could grow if California gets more
rain and snow, the allocation comes amid fresh weather
forecasts suggesting the dry winter is continuing. The National
Weather Service says the Sacramento Valley will be warm and
windy the next few days, with no rain in the forecast.
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. The goal is to provide river flows
and habitat for fish while still allowing enough water to be
diverted for farms and cities in a way that satisfies state
regulators.
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
Bruce Babbitt, the former Arizona
governor and secretary of the Interior, has been a thoughtful,
provocative and sometimes forceful voice in some of the most
high-profile water conflicts over the last 40 years, including
groundwater management in Arizona and the reduction of
California’s take of the Colorado River. In 2016, former
California Gov. Jerry Brown named Babbitt as a special adviser to
work on matters relating to the Sacramento-San Joaquin Delta and
the Delta tunnels plan.
The San Joaquin Valley, known as the
nation’s breadbasket, grows a cornucopia of fruits, nuts and
other agricultural products.
During our three-day Central Valley Tour April
3-5, you will meet farmers who will explain how they prepare
the fields, irrigate their crops and harvest the produce that
helps feed the nation and beyond. We also will drive through
hundreds of miles of farmland and visit the rivers, dams,
reservoirs and groundwater wells that provide the water.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
In the universe of California water, Tim Quinn is a professor emeritus. Quinn has seen — and been a key player in — a lot of major California water issues since he began his water career 40 years ago as a young economist with the Rand Corporation, then later as deputy general manager with the Metropolitan Water District of Southern California, and finally as executive director of the Association of California Water Agencies. In December, the 66-year-old will retire from ACWA.
The Colorado River Basin is more
than likely headed to unprecedented shortage in 2020 that could
force supply cuts to some states, but work is “furiously”
underway to reduce the risk and avert a crisis, Bureau of
Reclamation Commissioner Brenda Burman told an audience of
California water industry people.
During a keynote address at the Water Education Foundation’s
Sept. 20 Water Summit in Sacramento, Burman said there is
opportunity for Colorado River Basin states to control their
destiny, but acknowledged that in water, there are no guarantees
that agreement can be reached.
Get a unique view of the San Joaquin Valley’s key dams and
reservoirs that store and transport water on our March Central
Valley Tour.
Our Central Valley
Tour, March 14-16, offers a broad view of water issues
in the San Joaquin Valley. In addition to the farms, orchards,
critical habitat for threatened bird populations, flood bypasses
and a national wildlife refuge, we visit some of California’s
major water infrastructure projects.
This tour explored the Sacramento River and its tributaries
through a scenic landscape as participants learned 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 got an on-site update of repair efforts on the
Oroville Dam spillway.
One of the wettest years in California history that ended a
record five-year drought has rejuvenated the call for new storage
to be built above and below ground.
In a state that depends on large surface water reservoirs to help
store water before moving it hundreds of miles to where it is
used, a wet year after a long drought has some people yearning
for a place to sock away some of those flood flows for when they
are needed.
Our tours are famous for not only being packed with diverse
educational opportunities about California water, but showcasing
local culture. Our Central Valley Tour on March
8-10 lets you unwind at a few San Joaquin Valley treasures and
hear stories that go back generations.
The San Joaquin Valley has been hit hard by the six-year drought
and related surface water cutbacks. Some land has been fallowed
and groundwater pumping has increased. What does this year hold?
Will these recent heavy storms provide enough surface water for
improved water deliveries?
Your best opportunity to see and understand this vital
agricultural region of California is to join us on our annual
Central Valley Tour,
March 8-10.
Whiskeytown Lake, a major reservoir in the foothills of the
Klamath Mountains nine miles west of Redding, was
built at the site of one of Shasta County’s first Gold Rush
communities. Whiskeytown, originally called
Whiskey Creek Diggings, was founded in 1849 and named in
reference to a whiskey barrel rolling off a citizen’s pack mule;
it may also refer to miners drinking a barrel per day.
This 25-minute documentary-style DVD, developed in partnership
with the California Department of Water Resources, provides an
excellent overview of climate change and how it is already
affecting California. The DVD also explains what scientists
anticipate in the future related to sea level rise and
precipitation/runoff changes and explores the efforts that are
underway to plan and adapt to climate.
Salt. In a small amount, it’s a gift from nature. But any doctor
will tell you, if you take in too much salt, you’ll start to have
health problems. The same negative effect is happening to land in
the Central Valley. The problem scientists call “salinity” poses
a growing threat to our food supply, our drinking water quality
and our way of life. The problem of salt buildup and potential –
but costly – solutions are highlighted in this 2008 public
television documentary narrated by comedian Paul Rodriguez.
A 20-minute version of the 2008 public television documentary
Salt of the Earth: Salinity in California’s Central Valley. This
DVD is ideal for showing at community forums and speaking
engagements to help the public understand the complex issues
surrounding the problem of salt build up in the Central Valley
potential – but costly – solutions. Narrated by comedian Paul
Rodriquez.
This 3-day, 2-night tour travels the length of the San Joaquin
Valley, giving participants a clear understanding of the State
Water Project and Central Valley Project.
15-minute DVD that graphically portrays the potential disaster
should a major earthquake hit the Sacramento-San Joaquin Delta.
“Delta Warning” depicts what would happen in the event of an
earthquake registering 6.5 on the Richter scale: 30 levee breaks,
16 flooded islands and a 300 billion gallon intrusion of salt
water from the Bay – the “big gulp” – which would shut down the
State Water Project and Central Valley Project pumping plants.
30-minute DVD that traces the history of the U.S. Bureau of
Reclamation and its role in the development of the West. Includes
extensive historic footage of farming and the construction of
dams and other water projects, and discusses historic and modern
day issues.
Water truly has shaped California into the great state it is
today. And if it is water that made California great, it’s the
fight over – and with – water that also makes it so critically
important. In efforts to remap California’s circulatory system,
there have been some critical events that had a profound impact
on California’s water history. These turning points not only
forced a re-evaluation of water, but continue to impact the lives
of every Californian. This 2005 PBS documentary offers a
historical and current look at the major water issues that shaped
the state we know today. Includes a 12-page viewer’s guide with
background information, historic timeline and a teacher’s lesson.
This beautiful 24×36 inch poster, suitable for framing, features
a map of the San Joaquin River. The map text focuses on the San
Joaquin River Restoration Program, which aims to restore flows
and populations of Chinook salmon to the river below Friant Dam
to its confluence with the Merced River. The text discusses the
history of the program, its goals and ongoing challenges with
implementation.
Water as a renewable resource is depicted in this 18×24 inch
poster. Water is renewed again and again by the natural
hydrologic cycle where water evaporates, transpires from plants,
rises to form clouds, and returns to the earth as precipitation.
Excellent for elementary school classroom use.
The 28-page Layperson’s Guide to
Water Rights Law, recognized as the most thorough explanation of
California water rights law available to non-lawyers, traces the
authority for water flowing in a stream or reservoir, from a
faucet or into an irrigation ditch through the complex web of
California water rights.
The 20-page Layperson’s Guide to Water Marketing provides
background information on water rights, types of transfers and
critical policy issues surrounding this topic. First published in
1996, the 2005 version offers expanded information on
groundwater banking and conjunctive use, Colorado River
transfers and the role of private companies in California’s
developing water market.
Order in bulk (25 or more copies of the same guide) for a reduced
fee. Contact the Foundation, 916-444-6240, for details.
The 24-page Layperson’s Guide to
Flood Management explains the physical flood control system,
including levees; discusses previous flood events (including the
1997 flooding); explores issues of floodplain management and
development; provides an overview of flood forecasting; and
outlines ongoing flood control projects.
The 24-page Layperson’s Guide to
California Water provides an excellent overview of the history of
water development and use in California. It includes sections on
flood management; the state, federal and Colorado River delivery
systems; Delta issues; water rights; environmental issues; water
quality; and options for stretching the water supply such as
water marketing and conjunctive use. New in this 10th edition of
the guide is a section on the human need for water.
The 24-page Layperson’s Guide to the Central Valley Project
explores the history and development of the federal Central
Valley Project (CVP), California’s largest surface water delivery
system. In addition to the project’s history, the guide describes
the various CVP facilities, CVP operations, the benefits the CVP
brought to the state and the CVP Improvement Act (CVPIA).
With irrigation projects that import water, farmers have
transformed millions of acres of land into highly productive
fields and orchards. But the dry climate that provides an almost
year-round farming season can hasten salt build up in soils. The
build-up of salts in poorly drained soils can decrease crop
productivity, and there are links between drainage water from
irrigated fields and harmful impacts on fish and wildlife.
The 24-page Layperson’s Guide to the Delta explores the competing
uses and demands on California’s Sacramento-San Joaquin Delta.
Included in the guide are sections on the history of the Delta,
its role in the state’s water system, and its many complex issues
with sections on water quality, levees, salinity and agricultural
drainage, fish and wildlife, and water distribution.
A new look for our most popular product! And it’s the perfect
gift for the water wonk in your life.
Our 24×36 inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
California’s central coast is home to the San Felipe Division of
the federal Central
Valley Project. Authorized in the 1960s and completed in
1988, San Felipe Division includes a 5.3-mile-long tunnel (the
Pacheco Tunnel), pumping plant and other conduits.
It transports water west from the Central Valley’s San Luis
Reservoir near Los Banos to supply Santa Clara and the high-tech
Santa Clara Valley as well as parts of Santa Cruz, Monterey and
San Benito counties.
The Red Bluff Diversion Dam, its gates raised since 2011 to allow
fish passage, spans the Sacramento River two miles
southeast of Red Bluff on the Sacramento River in Tehama County.
It is owned by the Bureau of Reclamation and operated and
maintained by the Tehama-Colusa Canal Authority.
A part of the federal Central Valley Project, the Nimbus Dam and
its after bay, Lake Natoma, are located 7 miles downstream of
Folsom Dam on the American River.
The dam regulates American River flows. Other associated
facilities are the Nimbus Powerplant, the Nimbus Salmon and
Steelhead Hatchery and the Folsom South Canal. [see also Northern
California Water Tours.]
Construction began in 1937 to build the Contra Costa Canal, the
first part of the federal Central Valley
Project. The Contra Costa Canal runs from the Sacramento-San Joaquin
Delta, where it draws its water near Knightsen, to the
eastern and central parts of Contra Costa County. It is about 30
miles from San Francisco.
The Central Valley Project Improvement Act supports a major
federal effort to store and transport water in California’s
Central Valley.
The 1992 Act changed operations of Central Valley Project; a
major project that addresses flooding, storage and irrigation
issues in the valley [see also Central Valley Project].
Birthed in part by a long-ago federal effort to create farmland,
today the Central Valley Project is one of the largest water and
transport systems in the world. In years of normal precipitation,
it stores and distributes about 20 percent of the state’s
developed water through its massive system of reservoirs and
canals.
The C.W. Bill Jones Pumping Plant (formerly known as the Tracy
Pumping Plant) sits at the head of the 117-mile long Delta-Mendota Canal.
Completed in 1951, the canal begins near Tracy, Calif. and
follows the Coast Range south, providing irrigation water to the
west side of the San
Joaquin Valley along its route and terminating at Mendota
Pool.
This issue of Western Water looks at the BDCP and the
Coalition to Support Delta Projects, issues that are aimed at
improving the health and safety of the Delta while solidifying
California’s long-term water supply reliability.
This printed issue of Western Water features a
roundtable discussion with Anthony Saracino, a water resources
consultant; Martha Davis, executive manager of policy development
with the Inland Empire Utilities Agency and senior policy advisor
to the Delta Stewardship Council; Stuart Leavenworth, editorial
page editor of The Sacramento Bee and Ellen Hanak, co-director of
research and senior fellow at the Public Policy Institute of
California.
This printed issue of Western Water examines the issues
associated with the State Water Board’s proposed revision of the
water quality Bay-Delta Plan, most notably the question of
whether additional flows are needed for the system, and how they
might be provided.
This printed issue of Western Water examines the area
of origin laws, what they mean to those who claim their
protections and the possible implications of the Tehama Colusa
Canal Authority’s lawsuit against the Bureau of Reclamation.
This printed issue of Western Water provides an overview of the
idea of a dual conveyance facility, including questions
surrounding its cost, operation and governance
This printed copy of Western Water examines the native salmon and
trout dilemma – the extent of the crisis, its potential impact on
water deliveries and the lengths to which combined efforts can
help restore threatened and endangered species.
This printed copy of Western Water examines California’s drought
– its impact on water users in the urban and agricultural sector
and the steps being taken to prepare for another dry year should
it arrive.
The Reclamation Act of 1902, which could arguably be described as
a progression of the credo, Manifest Destiny, transformed the
West. This issue of Western Water provides a glimpse of the past
100 years of the Reclamation Act, from the early visionaries who
sought to turn the arid West into productive farmland, to the
modern day task of providing a limited amount of water to homes,
farms and the environment. Included are discussions of various
Bureau projects and what the next century may bring in terms of
challenges and success.
