Watch our series of short videos on the importance of the
Sacramento-San Joaquin Delta, how it works as a water hub for
California and the challenges it is facing.
When a person opens a spigot to draw a glass of water, he or she
may be tapping a source close to home or hundreds of miles away.
Water gets to taps via a complex web of aqueducts, canals and
groundwater.

Unlike California’s majestic rivers and massive dams and
conveyance systems, groundwater is out of sight and underground,
though no less plentiful. The state’s enormous cache of
underground water is a great natural resource and has contributed
to the state becoming the nation’s top agricultural producer and
leader in high-tech industries.
A new era of groundwater management began in 2014 in California
with the Sustainable Groundwater Management Act. The landmark law
turned 10 in 2024, with many challenges still ahead.
Our 41ˢᵗ annual Water
Summit, an engaging day of discussions addressing
critical water issues in California and across the West, will be
held on Wednesday, Oct. 1, in Sacramento with the theme,
Embracing Uncertainty in the West.
Speakers and conversations will explore how to move forward with
critical decisions despite myriad unknowns facing our most
precious natural resource, including updates and insights
from leadership at both the state and federal levels in shaping
water resource priorities in California and across the West.

Secretary Wade Crowfoot will be the keynote speaker at our
2025 Water
Summit where leading experts and top
policymakers will explore how to move forward with critical
decisions despite myriad unknowns facing the West’s most precious
natural resource.
Now in its 41ˢᵗ year, the Foundation’s premier annual event on
Oct. 1 in downtown Sacramento will focus on the theme,
Embracing Uncertainty in the West. A
full agenda featuring a slate of engaging panelists will be
available soon, but the day will be filled with lively
discussions on topics such as:
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.
In late July, PG&E officially submitted its plans to tear
down the Potter Valley Project, a century-old piece of
water infrastructure built to siphon flows from the Eel River
into the Russian River. The utility’s pending abandonment
of the project has led to fierce debates over agriculture,
tourism and healthy river ecosystems. … Yet as California
enters the height of its now never-ending fire season, one more
consequence of letting the Eel River run free looms: the
seasonal drying of the Russian River and the dissolution of
Lake Pillsbury, two water sources that fire chiefs in the
region have argued are crucial for wildfire-fighting efforts.
Lawyers for the Eastern Tule Groundwater Sustainability Agency
(GSA) recently fired a fusillade of legal arguments against
Friant Water Authority’s contention that the GSA shorted its
obligation to help pay for repairs to the sinking
Friant-Kern Canal. … Friant says Eastern Tule was
supposed to charge its landowners enough in pumping fees to
both pay Friant a minimum of $200 million and
disincentivize excessive pumping, which is what sank the canal
in the first place. But after four years, Friant collected only
$23 million because of what it says were Eastern Tule’s lenient
use of groundwater credits.
When most Californians think about where their water comes
from, they likely think of the state’s dams and reservoirs—and
they’re largely correct. … But another natural reservoir is
also essential to the state: snowpack. At the start of spring,
California’s snowpack has historically contained about 70% as
much water, on average, as all the state’s reservoirs combined.
… But warmer temperatures will result in more
precipitation falling as rain instead of snow, and snowpack
will melt earlier.
Operated by the U.S. Army Corps of Engineers, the
Bay Model is a giant hydraulic replica of San Francisco
Bay and the Sacramento-San Joaquin
Delta. It is housed in a converted World II-era
warehouse in Sausalito near San Francisco.
Hundreds of gallons of water are pumped through the
three-dimensional, 1.5-acre model to simulate a tidal ebb
and flow lasting 14 minutes.
As part of the historic Colorado
River Delta, the Salton Sea regularly filled and dried for
thousands of years due to its elevation of 237 feet below
sea level.
The most recent version of the Salton Sea was formed in 1905 when
the Colorado River broke
through a series of dikes and flooded the seabed for two years,
creating California’s largest inland body of water. The
Salton Sea, which is saltier than the Pacific Ocean, includes 130
miles of shoreline and is larger than Lake Tahoe.
Drought—an extended period of
limited or no precipitation—is a fact of life in California and
the West, with water resources following boom-and-bust patterns.
During California’s 2012–2016 drought, much of the state
experienced severe drought conditions: significantly less
precipitation and snowpack, reduced streamflow and higher
temperatures. Those same conditions reappeared early in 2021
prompting Gov. Gavin Newsom in May to declare drought emergencies
in watersheds across 41 counties in California.
