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.
Local growers and others met Friday for a triple tour of Madera
County water users and an on-farm groundwater recharge workshop
Wednesday. Participants visited AgriLand Farming Company in
Chowchilla, Galilee Missionary Baptist Church in Fairmead, and
the Ellis Recharge Basin in northeast Madera. These include
farmers struggling “to figure out how to farm” under the
state’s 2014 Sustainable Groundwater Management Act, which
requires the formation of local agencies to manage underground
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.

If California is going to prevent further depletion of aquifers
and survive droughts like the one that afflicted it from 2011
to 2017, the state will need to manage its groundwater usage.
In the central valley, a group of organizations is working on a
project that could stem the tide by combining two technologies:
the internet of things (IoT) and Blockchain.
A spectacular snowpack and a series of storms in the San
Joaquin Valley are bringing smiles to valley farmers’ faces. On
Friday, the Fresno Irrigation District started moving water to
farms in the cities of Fresno, Clovis, and their surrounding ag
land. While this isn’t an early start compared to typical
years, the water is especially welcome after several drought
It’s a treasure that is all too easy for Palo Alto to take for
granted — an abundant supply of pristine water that flows from
the Sierra Nevada snowpacks and passes through the Hetch Hetchy
system before splashing out of local showers and faucets. Palo
Alto is one of 25 cities that belong to the Bay Area Water
Supply and Conservation Agency (BAWSCA), which manages the
member cities’ supply agreement with the San Francisco Public
Utilities Commission. … Even so, the cities don’t always know
which projects they’re helping to fund.
Four new voting members, each appointed by representatives of
the Delta region, would be added to the Delta Stewardship
Council if a bill authored by Assemblyman Jim Frazier becomes
law. … Frazier introduced Assembly Bill 1194 this week. It

Funding awarded for the new Temperance Flat Dam may have fallen
short, but hopes for construction are still very much alive.
Jason Phillips, Director of Friant Water Authority and alumni
of the San Joaquin Valley Water Infrastructure Authority, has

To help build leadership capacity and acquire water management
tools for valley communities, Self-Help Enterprises invites
water board members and staff, water leaders, and residents
from rural communities to participate in the 2019 Rural
Communities Water Managers Leadership Institute. The six-month
program is scheduled for March through August, with sessions
held one Saturday per month at Self-Help Enterprises in
State Senator Melissa Hurtado (D-Sanger) said Senate Bill 559,
will “help secure California’s water supply by investing $400
million toward restoring lost (delivery) capacity on the
Friant-Kern Canal, one of the San Joaquin Valley’s most
critical water delivery facilities.” … The $400 million would
be appropriated from the state general fund to the Department
of Water Resources to administer the repairs.
Local groundwater regulatory agencies set up under 2014
legislation in California are discussing future rationing
schemes with irrigators as they scramble to submit long-term
aquifer sustainability plans to the state by a deadline of
early next year. Local regulators are discussing a combination
of new supplies and land-use conversions, says David Orth, a
principal at the Fresno-based New Current Water and Land, LLC,
a strategic planning firm.
The San Joaquin Valley—California’s largest agricultural region
and an important contributor to the nation’s food supply—is in
a time of great change. The valley produces more than half of
the state’s agricultural output. Irrigated farming is the
region’s main economic driver and predominant water user.
Stress on the valley’s water system is growing. Local water
supplies are limited, particularly in the southern half of the
The most eco-friendly wastewater treatment plant in the
Northern San Joaquin Valley will be Manteca’s by the time 2020
rolls around. Not only is the treated water returned to the San
Joaquin River meeting the latest standards established by the
state for water quality, but within six months or so methane
gas — a major byproduct of the treatment process that typically
has to be burned — will no longer contribute to valley air
This year, the water agency plans to inform farmers and the
community about not only the amount of water the Tuolumne River
Watershed has received so far this year, but also will provide
information regarding the final license application for Don
Pedro, which first began eight years ago, and the ongoing legal
battle surrounding the State Water Resources Control Board’s
decision to implement 40 percent unimpaired flows along the San
Joaquin River and its tributaries for the betterment of fish.
Since 2006, California has been releasing periodic reports on
how the state should adapt to the potential impacts of climate
change. The most recent report is unique in that it also looks
at key climate risks from a regional perspective. Our news
director Alice Daniel recently spoke with Joshua Viers, a
watershed scientist at UC Merced and one of the authors of the
San Joaquin Valley assessment.
Now stripped of its once vast wetlands and nearly sucked dry
from the overpumping of groundwater during the West’s
increasingly common droughts, the fertile valley is in need of
a reboot: Its aquifers have shrunk and the remaining water is
often contaminated with nitrate and salts. Citing a new water
law that will have major effects on water suppliers and
farmers, experts are calling for an “all hands on deck”
approach to fixing the valley’s water woes.
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.
