“Infrastructure” in general can be defined as the components and
equipment needed to operate, as well as the structures needed
for, public works systems. Typical examples include roads,
bridges, sewers and water supply systems.Various dams and
infrastructural buildings have given Californians and the West
the opportunity to control water, dating back to the days of
Native Americans.
Water management infrastructure focuses on the parts, including
pipes, storage reservoirs, pumps, valves, filtration and
treatment equipment and meters, as well as the buildings to
house process and treatment equipment. Irrigation infrastructure
includes reservoirs, irrigation canals. Major flood control
infrastructure includes dikes, levees, major pumping stations and
floodgates.
On Wednesday, the Tahoe City Public Utility District celebrated
the Grand Opening of the West Lake Tahoe Regional Water
Treatment Plant. … The plant can currently deliver one
million gallons of water per day and may be further expanded to
reach more customers from Tahoma to Timberland. The utility
district stated that the approximately $30 million project was
made possible by grant funding as well as a loan from the CA
State Water Resources Control Board.
Gov. Gavin Newsom and some of California’s major water agencies
hit a setback this week when a proposal to fast-track plans for
a 45-mile water tunnel beneath the Sacramento-San Joaquin River
Delta died in the state Legislature. … Delta lawmakers
said they were pleased that the governor’s proposal failed to
move forward in the final days of the legislative session.
… Newsom and supporters of the project say the tunnel is
essential to modernize the state’s water system for more severe
droughts and deluges with climate change.
House lawmakers will hear from senior Army Corps of Engineers
officials Wednesday on the status of federal water
infrastructure studies and projects. The Transportation and
Infrastructure Subcommittee on Water Resources and Environment
hearing will focus on the Army Corps’ implementation of
projects to reduce flooding and improve navigation that
Congress approved under the Water Resources Development Act.
… The hearing, “Water Resources Development Acts
Implementation: Review and Oversight of Past Provisions,” comes
as Democrats have accused the agency of delaying construction
of dam repairs and other infrastructure projects in blue
states, including Washington and California.
A new report shows America’s water systems need more than a
trillion dollars in upgrades in the coming decades. In the
West, states are dealing with shrinking reservoirs, worsening
drought, and a lack of data to plan for the future. Many
Western states use outdated methods to measure their water
system needs according to an analysis by Pew Charitable Trusts,
a nonpartisan research group. Some states don’t even have
inventories of basic assets, like aging pipes, or where lead
service lines still exist. … Nationwide, the
Environmental Protection Agency estimates water and wastewater
systems will need more than a trillion dollars in upgrades over
the next 20 years.
The Imperial Irrigation District (IID) officially declared a
local emergency at its regular meeting on Sept. 2, in response
to the catastrophic August 2025 Monsoon Storms that battered
its service territory in Imperial and Riverside counties. The
IID Board of Directors ratified the emergency proclamation
initially issued by Power Manager Matthew Smelser on Aug. 24,
acknowledging the extreme peril to public safety and property.
… Water Manager Mike Pacheco reported damage to the
Highline Canal, saying most of the destruction was in the
northwestern part of the valley along the Trifolium Canal to
the Elmore Desert Ranch.
… The Imperial Irrigation District, which delivers water to
farmers in southeastern California, adopted a resolution
endorsing the proposed Delta Conveyance Project on Tuesday,
despite not anticipating getting any of the project’s water
because of its sole reliance on the Colorado River. Instead,
the resolution says the district will benefit indirectly from
the project because it could relieve pressure on the Colorado
River from other California water agencies that can tap more
into Northern California’s Sacramento-San Joaquin Delta
instead.
California’s biggest irrigation district is throwing its
support behind a controversial water diversion project that
aims to help relieve the Golden State’s historic battle with
drought but also faces widespread local opposition. The
Imperial Irrigation District — the biggest district not only in
California, but also the nation — declared on Tuesday that it
was issuing “a significant and unusual endorsement” for the
state’s proposed Delta Conveyance Project.
… Although Imperial County is the only county in
Southern California that does not receive State Water Project
water, as it draws exclusively from the Colorado River, the
district adopted a resolution this week stressing the
importance of the proposed plans.
Governor Gavin Newsom is advancing the Sites Reservoir project
to expand California’s water storage capabilities, as the state
braces for water shortages impacting western states and the
looming threat of a hotter and drier future. The California
Water Commission has approved a nearly $219 million funding
increase for the project to ensure it progresses swiftly. The
additional funding is necessary due to increased costs from
delays, including inflation and anticipated construction cost
hikes.
The effort to build California’s largest new reservoir in
decades received a welcome commitment of cash on Wednesday —
nearly $220 million — which will help keep the project on track
to break ground as soon as next year. Planned for 70 miles
northwest of Sacramento, the proposed Sites Reservoir won the
bulk of the funding because plans to expand the Los Vaqueros
Reservoir in Contra Costa County fell through, freeing up money
in the state’s 2014 water bond. The remainder of the money for
Sites came from last year’s state climate bond.
The Delta Conveyance Project (DCP) continues to
advance as a state-of-the-art upgrade to California’s water
delivery system, ensuring a reliable and affordable water
supply for millions of residents across the state. As this
project moves forward, we remain focused on how it’s built
differently, engineered to withstand earthquakes, floods, and
climate-driven challenges while responding to impacts
in Delta communities and the environment. This
includes a $200 million Community Benefits Program to
support locally driven initiatives that reflect the values and
priorities of Delta communities. These investments are meant
to provide lasting benefits for all those who live
and work in the region.
… Updated modeling this spring found that Sites [Reservoir]
could have stored more than 550,000 acre-feet in just five
months of the current water year. … South of the Delta, the
proposed Del Puerto Canyon Reservoir … could store up to an
additional 82,000 acre-feet of new storage every year. …
[B]ut when the House debated an energy and natural resources
package earlier this year that included $2 billion dollars for
Central Valley water storage, I was the lone Democrat to vote
yes because reliable water is critical to my district and the
state. Most of the $1 billion that ended up in the final bill
is expected to support the enlargement of existing facilities,
such as Shasta Dam and San Luis Reservoir. This is a good
start, but many more projects are needed. –Written by Rep. Adam Gray, who represents California’s
13th Congressional District and serves on the House Natural
Resources Subcommittee on Water, Wildlife and Fisheries.
… Removing the Scott Dam, alongside the removal of the
smaller Cape Horn Dam downstream, both on the picturesque Eel
River, is part of PG&E’s plan to retire a century-old
hydroelectric operation known as the Potter Valley Project,
which the company says has gotten too expensive to run.
… Downstream communities along the Eel River as well as
environmental groups and tribes have cheered dam removal as a
way to restore the river’s natural flows. Long-declining salmon
and steelhead runs stand to benefit from the
restoration. At the same time, the plan has raised
concerns about power and water supplies in Northern California.
… Much less talked about is the fate of Lake Pillsbury.
In a landmark investment in regional water infrastructure,
South San Joaquin Irrigation District (SSJID) and Oakdale
Irrigation District (OID) have officially launched the $84
million Canyon Tunnel Project—an ambitious initiative to
protect and modernize water delivery for thousands of Central
Valley residents and farmers. … The 12,000-foot tunnel
will bypass a vulnerable section of the century-old Joint
Supply Canal (JSC), which has been increasingly threatened by
landslides and rockfalls. … The two districts are
jointly funding the project, with SSJID contributing 72% and
OID 28%, based on historical water usage from the shared
JSC.
The Department of Water Resources and the Newsom Administration
reiterated support for fast-tracking the Delta Conveyance
Project on Wednesday, announcing a plan aimed at helping
affected communities and holding the state
accountable. The goal of the Accountability Action Plan is
to minimize, avoid, or offset the potential impacts of project
construction on residents, businesses, tribes, visitors to the
Delta and many others. … The plan establishes a $200
million Community Benefits Program for areas near the
construction site. It will include community grants, economic
development, leave-behind/repurposed infrastructure, and
agreements for community-specific projects.
A project nearly five years in the making by community
partners, and now 53 homes, which includes over a hundred
people, in West Goshen have access to clean, safe and reliable
drinking water through their faucets. … Thanks to a $3.4
Million state grant, through The Safe and Affordable Funding
for Equity and Resilience Program, SAFER, Goshen homes have now
been connected to Cal Water’s public water system. … The
Community Water Center has been providing water bottles and
jugs to locals for years. … The nonprofit says the
project should be complete within the next week and hopes to
continue reaching other communities in Tulare County, including
areas near Porterville and Cutler-Orosi.
Cities across California and the Southwest are significantly
increasing and diversifying their use of recycled wastewater as
traditional water supplies grow tighter.
The 5th edition of our Layperson’s Guide to Water Recycling
covers the latest trends and statistics on water reuse as a
strategic defense against prolonged drought and climate change.
As the permitting battle over the proposed Sites Reservoir
Project in Northern California heats up, it’s become clear that
the project would further heat up the atmosphere as well. Just
as California has made bold commitments to achieve carbon
neutrality in the next few decades, the state seems ready to
approve a dam project that would put that progress in jeopardy.
A new report, “Estimate of Greenhouse Gas Emissions for the
Proposed Sites Reservoir Project Using the All-Res Modeling
Tool,” created by a science team at my organization, Tell The
Dam Truth, exposes the climate impacts caused by this massive
dam and reservoir system. -Written by Gary Wockner, PhD, who directs Tell The
Dam Truth
Residents living below the Isabella Auxiliary Dam were thrilled
earlier this month with a temporary fix that finally dried up
excessive seepage from the dam that had been swamping septic
systems and breeding forests of mosquito-infested weeds around
their homes. The didn’t realize how temporary the fix would be,
however. After only 12 days without a river cutting through his
land, rancher Gerald Wenstrand woke up to see the seepage back
on Saturday.
It was exactly the sort of deluge
California groundwater agencies have been counting on to
replenish their overworked aquifers.
The start of 2023 brought a parade of torrential Pacific storms
to bone dry California. Snow piled up across the Sierra Nevada at
a near-record pace while runoff from the foothills gushed into
the Central Valley, swelling rivers over their banks and filling
seasonal creeks for the first time in half a decade.
Suddenly, water managers and farmers toiling in one of the
state’s most groundwater-depleted regions had an opportunity to
capture stormwater and bank it underground. Enterprising agencies
diverted water from rushing rivers and creeks into manmade
recharge basins or intentionally flooded orchards and farmland.
Others snagged temporary permits from the state to pull from
streams they ordinarily couldn’t touch.
Managers of California’s most
overdrawn aquifers were given a monumental task under the state’s
landmark Sustainable Groundwater Management Act: Craft viable,
detailed plans on a 20-year timeline to bring their beleaguered
basins into balance. It was a task that required more than 250
newly formed local groundwater agencies – many of them in the
drought-stressed San Joaquin Valley – to set up shop, gather
data, hear from the public and collaborate with neighbors on
multiple complex plans, often covering just portions of a
groundwater basin.
Martha Guzman recalls those awful
days working on water and other issues as a deputy legislative
secretary for then-Gov. Jerry Brown. California was mired in a
recession and the state’s finances were deep in the red. Parks
were cut, schools were cut, programs were cut to try to balance a
troubled state budget in what she remembers as “that terrible
time.”
She now finds herself in a strikingly different position: As
administrator of the U.S. Environmental Protection Agency’s
Region 9, she has a mandate to address water challenges across
California, Nevada, Arizona and Hawaii and $1 billion to help pay
for it. It is the kind of funding, she said, that is usually
spread out over a decade. Guzman called it the “absolutely
greatest opportunity.”
When you oversee the largest
supplier of treated water in the United States, you tend to think
big.
Jeff Kightlinger, general manager of the Metropolitan Water
District of Southern California for the last 15 years, has
focused on diversifying his agency’s water supply and building
security through investment. That means looking beyond MWD’s
borders to ensure the reliable delivery of water to two-thirds of
California’s population.
As California slowly emerges from
the depths of the COVID-19 pandemic, one remnant left behind by
the statewide lockdown offers a sobering reminder of the economic
challenges still ahead for millions of the state’s residents and
the water agencies that serve them – a mountain of water debt.
Water affordability concerns, long an issue in a state where
millions of people struggle to make ends meet, jumped into
overdrive last year as the pandemic wrenched the economy. Jobs
were lost and household finances were upended. Even with federal
stimulus aid and unemployment checks, bills fell by the wayside.
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.
Across a sprawling corner of southern Tulare County snug against the Sierra Nevada, a bounty of navel oranges, grapes, pistachios, hay and other crops sprout from the loam and clay of the San Joaquin Valley. Groundwater helps keep these orchards, vineyards and fields vibrant and supports a multibillion-dollar agricultural economy across the valley. But that bounty has come at a price. Overpumping of groundwater has depleted aquifers, dried up household wells and degraded ecosystems.
Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed
them.
It’s been a year since two devastating wildfires on opposite ends
of California underscored the harsh new realities facing water
districts and cities serving communities in or adjacent to the
state’s fire-prone wildlands. Fire doesn’t just level homes, it
can contaminate water, scorch watersheds, damage delivery systems
and upend an agency’s finances.
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.
For the bulk of her career, Jayne
Harkins has devoted her energy to issues associated with the
management of the Colorado River, both with the U.S. Bureau of
Reclamation and with the Colorado River Commission of Nevada.
Now her career is taking a different direction. Harkins, 58, was
appointed by President Trump last August to take the helm of the
United States section of the U.S.-Mexico agency that oversees
myriad water matters between the two countries as they seek to
sustainably manage the supply and water quality of the Colorado
River, including its once-thriving Delta in Mexico, and other
rivers the two countries share. She is the first woman to be
named the U.S. Commissioner of the International Boundary and
Water Commission for either the United States or Mexico in the
commission’s 129-year history.
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.
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.
There’s going to be a new governor
in California next year – and a host of challenges both old and
new involving the state’s most vital natural resource, water.
So what should be the next governor’s water priorities?
That was one of the questions put to more than 150 participants
during a wrap-up session at the end of the Water Education
Foundation’s Sept. 20 Water Summit in Sacramento.
New water storage is the holy grail
primarily for agricultural interests in California, and in 2014
the door to achieving long-held ambitions opened with the passage
of Proposition
1, which included $2.7 billion for the public benefits
portion of new reservoirs and groundwater storage projects. The
statute stipulated that the money is specifically for the
benefits that a new storage project would offer to the ecosystem,
water quality, flood control, emergency response and recreation.
It’s high-stakes time in Arizona. The state that depends on the
Colorado River to help supply its cities and farms — and is
first in line to absorb a shortage — is seeking a unified plan
for water supply management to join its Lower Basin neighbors,
California and Nevada, in a coordinated plan to preserve water
levels in Lake Mead before
they run too low.
If the lake’s elevation falls below 1,075 feet above sea level,
the secretary of the Interior would declare a shortage and
Arizona’s deliveries of Colorado River water would be reduced by
320,000 acre-feet. Arizona says that’s enough to serve about 1
million households in one year.
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

major water infrastructure projects.
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.
Contrary to popular belief, “100-Year Flood” does not refer to a
flood that happens every century. Rather, the term describes the
statistical chance of a flood of a certain magnitude (or greater)
taking place once in 100 years. It is also accurate to say a
so-called “100-Year Flood” has a 1 percent chance of occurring in
a given year, and those living in a 100-year floodplain have,
each year, a 1 percent chance of being flooded.
Mired in drought, expectations are high that new storage funded
by Prop. 1 will be constructed to help California weather the
adverse conditions and keep water flowing to homes and farms.
At the same time, there are some dams in the state eyed for
removal because they are obsolete – choked by accumulated
sediment, seismically vulnerable and out of compliance with
federal regulations that require environmental balance.
The proposed Sites Reservoir would
be an off-river storage basin on the west side of the Sacramento
Valley, about 78 miles northwest of Sacramento. It would capture
stormwater flows from the Sacramento River for release in dry
years for fish and wildlife, farms, communities and
businesses.
The water would be held in a 14,000-acre basin of grasslands
surrounded by the rolling eastern foothills of the Coast Range.
Known as Antelope Valley, the sparsely populated area in Glenn
and Colusa counties is used for livestock grazing.

The 24-page Layperson’s Guide to the State Water Project provides
an overview of the California-funded and constructed State Water
Project.
The State Water Project is best known for the 444-mile-long
aqueduct that provides water from the Delta to San Joaquin Valley
agriculture and southern California cities. The guide contains
information about the project’s history and facilities.
The 24-page Layperson’s Guide to Integrated Regional Water
Management (IRWM) is an in-depth, easy-to-understand publication

the various facilities, operations and benefits the water
project brings to the state along with the CVP
Improvement Act (CVPIA).
This printed issue of Western Water examines water
infrastructure – its costs and the quest to augment traditional
brick-and-mortar facilities with sleeker, “green” features.
Everywhere you look water infrastructure is working hard to keep
cities, farms and industry in the state running. From the massive
storage structures that dot the West to the aqueducts that convey
water hundreds of miles to large urban areas and the untold miles
of water mains and sewage lines under every city and town, the
semiarid West would not exist as it does without the hardware
that meets its water needs.
This printed issue of Western Water discusses low
impact development and stormwater capture – two areas of emerging
interest that are viewed as important components of California’s
future water supply and management scenario.
This printed issue of Western Water examines
groundwater banking, a water management strategy with appreciable
benefits but not without challenges and controversy.
This printed issue of Western Water examines the
changed nature of the California Water Plan, some aspects of the
2009 update (including the recommendation for a water finance
plan) and the reaction by certain stakeholders.
This printed issue of Western Water looks at some of
the pieces of the 2009 water legislation, including the Delta
Stewardship Council, the new requirements for groundwater
monitoring and the proposed water bond.
It’s no secret that providing water in a state with the size and
climate of California costs money. The gamut of water-related
infrastructure – from reservoirs like Lake Oroville to the pumps
and pipes that deliver water to homes, businesses and farms –
incurs initial and ongoing expenses. Throw in a new spate of
possible mega-projects, such as those designed to rescue the
ailing Sacramento-San Joaquin Delta, and the dollar amount grows
exponentially to billion-dollar amounts that rival the entire
gross national product of a small country.
This printed issue of Western Water examines the
financing of water infrastructure, both at the local level and
from the statewide perspective, and some of the factors that
influence how people receive their water, the price they pay for
it and how much they might have to pay in the future.
They are located in urban areas and in some of the most rural
parts of the state, but they have at least one thing in common:
they provide water service to a very small group of people. In a
state where water is managed and delivered by an organization as
large as the Metropolitan Water District of Southern California,
most small water systems exist in obscurity – financed by
shoestring budgets and operated by personnel who wear many hats.
This issue of Western Water looks at water
infrastructure – from the large conveyance systems to the small
neighborhood providers – and the many challenges faced by water
agencies in their continuing mission of assuring a steady and
reliable supply for their customers.
Chances are that deep within the ground beneath you as you read
this is a vast network of infrastructure that is busy providing
the necessary services that enable life to proceed at the pace it
does in the 21st century. Electricity zips through cables to
power lights and computers while other conduits move infinite
amounts of information that light up computer screens and phone
lines.
This issue of Western Water explores the question of whether the
state needs more surface storage, with a particular focus on the
five proposed projects identified in the CALFED 2000 ROD and the
politics and funding issues of these projects.
