The San Joaquin River, which helps
drain California’s Central Valley, has been negatively impacted
by construction of dams, inadequate streamflows and poor water
quality. Efforts are now underway to restore the river and
continue providing agricultural lands with vital irrigation,
among other water demands.
After an 18-year lawsuit to restore water flows to a 60-mile dry
stretch of river and to boost the dwindling salmon populations,
the San Joaquin River Restoration Settlement is underway.
Water releases are now used to restore the San Joaquin River and
to provide habitat for naturally-reproducing populations of
self-sustaining Chinook salmon and other fish in the San Joaquin
River. Long-term efforts also include measures to reduce or avoid
adverse water supply impacts from the restoration flows.
The Sacramento Superior Court has ruled in favor of the State
Water Board’s 2018 Bay Delta Plan update, denying all 116
claims by petitioners. In December 2018, the State Water
Resources Control Plan adopted revised flow
objectives for the San Joaquin River and its three major
tributaries, the Stanislaus, Tuolumne, and Merced rivers. The
new flow objectives provide for increased flows on the three
tributaries to help revive and protect native fall-run
migratory fish populations. The Board also adopted a revised
south Delta salinity objectives, increasing the level of
salinity allowed from April to August. Several petitions
were filed in several counties challenging the Board’s
action.
Just south of Dos Rios Ranch, a much-praised effort at river
restoration, another such project is taking root. It will add
about 380 acres of floodplain and other habitat to the 1,600
acres at Dos Rios. They are near the confluence of the Tuolumne
and San Joaquin rivers, about eight miles southwest of Modesto.
The state-funded project, totaling about $20.8 million, is on
the former Hidden Valley Dairy. Annual feed crops are giving
way to oaks, cottonwoods, willows and other native plants. The
floodplain will take on high river flows that otherwise could
threaten nearby Grayson and downstream towns. The standing
water could recharge the aquifer below for use during droughts.
The place could offer food and shelter to fish, birds, mammals
and other creatures.
California has lost most of its natural wetlands as rivers have
been cut off from their natural floodplains. And it’s pretty
remarkable what can be achieved when rivers are given space to
reconnect with floodplains. I learned more about opening up
spaces for rivers to roam while working on an article about
floodplain restoration efforts in the Central Valley. These
types of projects have received broad-based support in recent
years as an effective nature-based solution that can bring
various interrelated benefits. They include: reducing the risks
of flooding in vulnerable communities downstream; capturing and
storing more water underground in aquifers; improving water
quality; and helping to repair ecosystems.
… Natural floodplains — the lush green lands along
rivers that historically flooded, retained water, and nourished
life in the heart of the valley — were mostly drained and
converted to farmland generations ago as the state’s waters
were dammed and diverted. Today, an effort to bring back
some of those floodplains is flourishing at the 2,100-acre Dos
Rios Ranch Preserve near Modesto, where workers years ago
planted native trees on retired farm fields and removed berms
to create space for water to spread out again. … By making
room for the rivers to overflow, the restoration project has
created an outlet for high flows that helps to reduce the risk
of dangerous flooding in low-lying communities nearby.
The Bay Delta Plan should focus more on the amount of water
flowing through rivers and less on habitat restorations to
restore its ecosystems, according to Environmental Protection
Agency (EPA) comments submitted to the State Water Resources
Control Board. The Water Board, which is in the process of
revising its draft Bay Delta Plan for public review, will
decide what river-flow requirements and water-quality controls
will govern uses within the Sacramento River watershed. The
EPA’s comments came as part of the plan’s public comment
period, which closed on Jan. 19.
A motion that challenged four claims made in a lawsuit against
the City of Bakersfield over how it operates the Kern River got
a half-and-half ruling from Kern County Superior Court Judge
Gregory Pulskamp Monday evening. However, the heart of the
lawsuit – that Bakersfield breached its duties under the Public
Trust Doctrine by dewatering the river through town – will
remain intact. “The City does not have the discretion to ignore
its statutory and public trust duties,” Pulskamp’s ruling
states. The judge also overruled opponents’ arguments that the
Kern River isn’t subject to California Fish and Game Code 5937,
which requires dam owners to allow enough water to pass those
structures to keep downstream fish in good conditions.
Opponents had argued that structures used to divert water out
of the Kern River are weirs, or “conduits,” not dams. Pulskamp
noted the code includes “all artificial obstructions” in its
definition of dams.
Residents of Woodlake in Tulare County, traumatized by the
devastation of last year’s floods, watched in fear last week as
storms dumped water on their town, flooding streets. When
his street flooded last week, Joshua Diaz got word while he was
at work teaching at Porterville High School. He rushed
home to blockade his home with sandbags. Even though his home
wasn’t damaged again, the experience was too close for
comfort. “I honestly thought it was going to be a repeat
of last year,” said Diaz … Diaz’s house was inundated
last year, destroying much of the structure and his family’s
belongings.
Though the Delta Conveyance Project was only recently
approved by the Department of Water Resources after completing
the lengthy California Environmental Quality Act (CEQA)
process, the project faces new obstacles to implementation.
Nine lawsuits challenging DWR’s December 21, 2023 approval of
the Project were recently filed in Sacramento County Superior
Court by a total of thirty-three plaintiffs representing all
the Delta counties, the City of Stockton, environmental and
other nongovernmental organizations, and tribe[s]. Resolution
of that litigation could take several years.
Growing up in the shadow of the
Rocky Mountains, Andrew Schwartz never missed an opportunity to
play in – or study – a Colorado snowstorm. During major
blizzards, he would traipse out into the icy wind and heavy
drifts of snow pretending to be a scientist researching in
Antarctica.
Decades later, still armed with an obsession for extreme weather,
Schwartz has landed in one of the snowiest places in the West,
leading a research lab whose mission is to give California water
managers instant information on the depth and quality of snow
draping the slopes of the Sierra Nevada.
This tour traveled along the San Joaquin River to learn firsthand
about one of the nation’s largest and most expensive river
restoration projects.
The San Joaquin River was the focus of one of the most
contentious legal battles in California water history,
ending in a 2006 settlement between the federal government,
Friant Water Users Authority and a coalition of environmental
groups.

This tour ventured 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.
Land and waterway managers labored
hard over the course of a century to control California’s unruly
rivers by building dams and levees to slow and contain their
water. Now, farmers, environmentalists and agencies are undoing
some of that work as part of an accelerating campaign to restore
the state’s major floodplains.
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.
California is chock full of rivers and creeks, yet the state’s network of stream gauges has significant gaps that limit real-time tracking of how much water is flowing downstream, information that is vital for flood protection, forecasting water supplies and knowing what the future might bring.
That network of stream gauges got a big boost Sept. 30 with the signing of SB 19. Authored by Sen. Bill Dodd (D-Napa), the law requires the state to develop a stream gauge deployment plan, focusing on reactivating existing gauges that have been offline for lack of funding and other reasons. Nearly half of California’s stream gauges are dormant.
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.
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 whims of political fate decided
in 2018 that state bond money would not be forthcoming to help
repair the subsidence-damaged parts of Friant-Kern Canal, the
152-mile conduit that conveys water from the San Joaquin River to
farms that fuel a multibillion-dollar agricultural economy along
the east side of the fertile San Joaquin Valley.
The Sacramento and San Joaquin
rivers are the two major Central Valley waterways that feed the
Delta, the hub of California’s water supply
network. Our last water tours of
2018 will look in-depth at how these rivers are managed and
used for agriculture, cities and the environment. You’ll see
infrastructure, learn about efforts to restore salmon runs and
talk to people with expertise on these rivers.
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.
