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.
Although ending groundwater overdraft will bring long-term
benefits, it entails near-term costs. We find that only about a
quarter of the Valley’s groundwater deficit can be filled with
new supplies at prices farmers can afford. The rest must come
from managing demand. We estimate that ending the overdraft
will require taking at least 500,000 acres of irrigated
cropland out of production.
When it floods in California, the culprit is usually what’s
known as an atmospheric river—a narrow ribbon of ultra-moist
air moving in from over the Pacific Ocean. Atmospheric rivers
are also essential sources of moisture for western reservoirs
and mountain snowpack, but in 1861, a series of particularly
intense and prolonged ones led to the worst disaster in state
history: a flood that swamped the state. What would happen if
the same weather pattern hit the state again?
In December, the city began delivering recycled water through
its purple pipeline to the Tulare Irrigation District (TID)
following approval by the Department of Drinking Water (DDW).
Under an agreement signed in 2013, the city is obligated to
deliver 11,000 acre feet of recycled water to TID per year in
exchange for 5,500 acre feet of surface water used to recharge
the city’s groundwater. Since 2016, the city has received
enough surface water from TID to off set one year of
groundwater pumping for the entire city.
It’s shaping up as a wetter-than-usual winter in California,
putting to rest fears of another drought hitting anytime soon.

A federal environmental analysis recommends relicensing the Don
Pedro hydroelectric project and accepts a Modesto and Turlock
irrigation district plan for well-timed flows to boost salmon
in the Tuolumne River. The flows, combined with other measures
to assist spawning and outmigrating young salmon, would commit
less water to the environment than a State Water Resources
Control Board plan that’s unpopular in the Northern San Joaquin
Felicia Marcus, whose push for larger river flows angered
farmers and community leaders in the Northern San Joaquin
Valley, won’t continue as chairwoman of the State Water
Resources Control Board. Gov. Gavin Newsom named Joaquin
Esquivel as chairman of the powerful water regulatory board.
… Laurel Firestone, co-founder of the Community Water
Center, was appointed as the replacement for Marcus.
… Firestone has been an advocate for addressing wells
contaminated with nitrates.
Despite many high priority issues on his plate, one of Gov.
Gavin Newsom’s first tests will be how he deals with
California’s water challenges and opportunities. Unfortunately,
in the last days of his term Gov. Jerry Brown made a bad
bargain with the Trump administration and special interests.
It’s yet another mess for the new governor to mop up.
An assortment of groups … joined the legal fray in courts
over the State Water Board decision in December to reduce water
diversions for farms and cities from the Tuolumne, Stanislaus
and Merced rivers. The emotions leading up to the Dec. 12
decision have touched off debate on what exactly could
restore a severely impaired delta estuary and depleted salmon
populations and what it will cost for Central Valley
While campaigning for president in 2016, Donald Trump promised
a cheering Fresno crowd he would be “opening up the
water” for Central Valley farmers… Trump took one of the
most aggressive steps to date to fulfill that promise Tuesday
by proposing to relax environmental regulations governing how
water is shared between fish and human uses throughout the
The California Farm Bureau Federation has filed a lawsuit to
block by the State Water Resources Control Board’s plans for
the lower river flow of San Joaquin River. In a press release,
the Farm Bureau said that the Board’s plan , which was adopted
last December, “misrepresents and underestimates the harm it
would cause to agricultural resources in the Central Valley”.
Maintaining functional wetlands in a 21st-century landscape
dominated by agriculture and cities requires a host of hard and
soft infrastructures. Canals, pumps, and sluice gates provide
critical life support, and the lands are irrigated and tilled
in seasonal cycles to essentially farm wildlife. Reams of laws
and regulations scaffold the system.
The City of Lathrop is one step closer to earning a permit that
will allow for the discharge of treated wastewater straight
into the San Joaquin River. … Currently the City of
Lathrop disposes of the effluent that is generated from the
Lathrop Consolidated Treatment Facility by storing it in basins
during the winter months, and then applying it to urban or
agricultural landscapes during the summer months.
The Santa Clara Valley Water District made a grave
miscalculation in suing the State Water Board over
the Bay Delta Water Quality Control Plan. By alienating the
remnants of the environmental community who have supported them
in recent years, they are jeopardizing future projects and
funding measures that will require voter approval.
In an unprecedented move, the Water Resources Control board
voted in December to require water users to leave more water in
the lower San Joaquin River to improve water quality and help
fish. “This decision represents the water board taking its job
to protect the public trust and our fisheries more seriously,”
said Regina Chichizola, salmon and water policy analyst for the
Institute for Fisheries Resources.
When it comes to water, the lifeblood of the Central Valley,
Democrats don’t have all the answers. So says freshman
Representative Josh Harder, suddenly one of the most powerful
Democrats in these parts. … “We need to make sure we’re
all working together to advance the agenda of the Central
Valley,” continued Harder, 32, of Turlock. “I was very
encouraged to see some of the measures the Trump
administration put forward on water.”
Since taking office Jan. 7, Gov. Gavin Newsom has not
indicated how he intends to approach one of the state’s most
pressing issues: water. Newsom should signal that
it’s a new day in California water politics by embracing
a more-sustainable water policy that emphasizes
conservation and creation of vast supplies of renewable
water. The first step should be to announce the
twin-tunnels effort is dead.
Citing what they say would be a disastrous decision for the
region, the Oakdale and South San Joaquin Irrigation Districts
have joined with other members of the San Joaquin Tributaries
Authority (SJTA) in a lawsuit challenging the state’s right to

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.
Land subsidence from overpumping of San Joaquin Valley
groundwater sank portions of the Friant-Kern Canal, the
152-mile conduit that conveys water from the San Joaquin River
to farms that help fuel a multibillion-dollar agricultural
economy. A plan to fix it helped sink the $8.8 billion
Proposition 3 bond measure last November. Now San Joaquin
Valley water managers are trying to figure out another way to
restore the canal, not only to keep farmers farming, but to aid
the valley’s overtaxed groundwater aquifers. By Gary
Pitzer in Western Water.
Most of the native habitat in California’s San Joaquin Desert
has been converted to row crops and orchards, leaving 35
threatened or endangered species confined to isolated patches
of habitat. A significant portion of that farmland, however, is
likely to be retired in the coming decades due to groundwater
overdraft, soil salinity, and climate change. A new study
… found that restoration of fallowed farmland could play a
crucial role in habitat protection and restoration strategies
