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.
State legislators denied a local lawmaker’s bill to stop a
mining project that proposes to drill and blast a 600-foot pit
along the San Joaquin River and is undergoing its environmental
review. On Monday, the California Assembly Committee on Natural
Resources voted down AB 1425 from Assemblymember Joaquin
Arambula, D-Fresno, though it may come back up in January 2026
for absent committee members to consider, said committee chair
Isaac Bryan, D-Baldwin Hills. The “narrowly tailored” bill,
according to Arambula, would have stopped Mexico-based CEMEX
from emptying water from mining pits, which he said risks
contaminating the river and overdrafting water along the river.
By banning “dewatering,” the company’s plan to dig the 600-foot
pit would not only be stopped, but it would force the company
to cease its current operations as well, CEMEX representative
Scott Govenar said at the hearing.
If the San Joaquin River is to be protected from further harm
at the hands of a multinational mining company with a history
of environmental violations, help won’t be arriving from the
state capitol. A bill authored by Assemblymember Joaquin
Arambula (D-Fresno) aimed at squelching CEMEX’s controversial
blast mine failed to advance from its first committee hearing
Monday afternoon in Sacramento. Only one member of the Assembly
Natural Resources Committee voted “aye” on AB 1425 compared to
13 “noes” and no votes, killing the bill for this legislative
session. That does not mean CEMEX gets the green light to start
drilling and blasting 200 feet away from the river 3 miles
outside the Fresno city limits. Goodness no. It simply means
the process for potential approval will continue as prescribed
by the California Environmental Quality Act. –Written by Fresno Bee opinion columnist Marek
Warszawski.
A bill introduced by Assemblyman Joaquin Arambula aimed at
stopping a century-long mining project in Fresno County did not
make it out of committee Monday afternoon. That mining project
would drill a 600-foot deep pit near the San Joaquin River in
Fresno County. Arambula introduced a bill, AB1425, which went
before the Natural Resources Committee in Sacramento this
afternoon. It would have disqualified building materials
company CEMEX’s proposed 100-year mining expansion project
utilizing hard rock mining, blasting and drilling that deep
pit. … The San Joaquin River Parkway and Conservation Trust
has been strongly opposed to the project because of its
potential impact on the environment.
Fresno Assemblyman Joaquin Arambula will host a town hall
Thursday evening to rally opposition against CEMEX’s proposed
blast mine along the San Joaquin River, a project critics warn
could contaminate groundwater and damage critical habitat. The
April 24 event at the River Center will feature presentations
on the environmental impacts of the mining giant’s expansion
plans and highlight Arambula’s legislation aimed at blocking
the project. … “The CEMEX Rockfield Expansion poses a serious
threat to wildlife, water quality, air quality, and the
long-term vision for the San Joaquin River Parkway. This is a
critical moment for our community to get informed, get
involved, and make your voices heard,” the flyer for the event
reads.
Construction on a $2 billion levee project that will
effectively protect more than a third of Stocktonians’ homes
from flooding kicked off this week. Local government
officials took part in a groundbreaking ceremony Friday off
March Lane at the Tenmile Slough in Brookside to launch the
Lower San Joaquin River Improvement Project. … The first
phase of the project, slated for completion in late 2026, will
see improvements made to just over a mile of the Tenmile Slough
levee, which sits directly in the backyard of many homes in the
Brookside area of west Stockton, according to a presentation on
the project’s overview. About one mile of the levee will be
upgraded to have a seepage cutoff wall, which is an added layer
of material preventing water seeping through or under the
levee.
A mining company wants to dig hundreds of feet down on a site
along the San Joaquin River. With an environmental review of
the project released, the decision now lands on Fresno County
supervisors to approve or deny — and, if the project gets a
green light, decide how deep to allow the company to dig.
Mexico-based mining company CEMEX wants to dig a 600-foot hole
and blast hard rock from its quarry site about 200 feet from
the banks of the San Joaquin River, according to Fresno
County’s environmental impact report. The company already mines
aggregate at its quarry. A permit to operate expires in July
2026. However, a new California legislative bill may decide the
future of mining on the prime river land, bypassing the
supervisors. Assembly Bill 1425 from Joaquin
Arambula (D-Fresno) would ban dewatering from many sites along
the San Joaquin River — effectively killing the CEMEX proposal.
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.
For more than 100 years, invasive
species have made the Sacramento-San Joaquin Delta their home,
disrupting the ecosystem and costing millions of dollars annually
in remediation.
The latest invader is the nutria, a large rodent native to South
America that causes concern because of its propensity to devour
every bit of vegetation in sight and destabilize levees by
burrowing into them. Wildlife officials are trapping the animal
and trying to learn the extent of its infestation.
Along the banks of the
Sacramento-San Joaquin Delta in Oakley, about 50 miles southwest
of Sacramento, is a park that harkens back to the days when the
Delta lured Native Americans, Spanish explorers, French fur
trappers, and later farmers to its abundant wildlife and rich
soil.
That historical Delta was an enormous marsh linked to the two
freshwater rivers entering from the north and south, and tidal
flows coming from the San Francisco Bay. After the Gold Rush,
settlers began building levees and farms, changing the landscape
and altering the habitat.
