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.
Calling all future water leaders! Are you an emerging leader
passionate about shaping the future of water in California
or across the Colorado River Basin?
The Water Education Foundation will
be hosting two dynamic water leadership programs in 2026 – one
focused on California water
issues and the other on the Colorado River
Basin. These competitive programs are designed for
rising stars from diverse sectors who are ready to deepen their
water knowledge, strengthen their leadership skills and
collaborate on real-world water challenges.
Are you an
up-and-coming leader in the water world? The application
window is now open for our 2026 California Water
Leaders cohort, and submissions are due no later than Dec.
3, 2025.
If interested in applying, start by checking out the
program
requirementsand look at the
frequently asked questions and mandatory
dates on
the application page. Make sure you have the time to
commit to the program next year and approval from your
organization to apply.
Then sign
up here to join a virtual Q&A
session on Nov. 5 at noon with Jenn Bowles,
our executive director, and other Foundation team members to get
an overview of the program and advice on applying.
Evacuation warnings were issued across Los Angeles County on
Thursday evening as an atmospheric river approached Southern
California, bringing with it the potential to put an early end
to fire season while also bringing fresh risks of
flooding and mudslides. Under the storm
scenario deemed most likely by forecasters, downtown L.A. would
see 2.62 inches of rain Friday morning through Sunday. … Rain
of that extent would also make this L.A.’s wettest November in
40 years. … In Sierra Nevada, snow levels are
expected to fall to around 8,000 feet above sea level
around Tahoe and in Mono County from Thursday night into Friday
morning.
Delta Caucus co-chairs, Assemblywoman Lori Wilson and Sen.
Jerry McNerney on Thursday called on the Delta Protection
Commission to file an official appeal of the certification “of
the costly and destructive Delta Tunnel Project.” “The
Legislature established the Delta Protection Commission to
‘protect, restore, and enhance the Delta ecosystem,’ so we call
on the commission to appeal the certification of the Delta
Tunnel Project because it will devastate communities, farms,
the environment, and historic and cultural resources
surrounding the largest and most important estuary on the West
Coast,” Wilson, D-Suisun City, and McNerney, D-Pleasanton, said
in a joint statement.
A late fall storm that soaked the North State and brought high
wind gust is padding rain totals for what has been a wet start
to Northern California’s water year. … November is
typically the month when Lake Shasta, the state’s
largest manmade reservoir, drops to its lowest level
for the year. But the lake’s level is trending higher so far
this year. Lake Shasta is at 106% of the historical average and
57% full, the California Department of Water Resources said.
Trinity Lake was 71% full, which is 123% of the historical
average.
Two Northern California tribes announced Wednesday that they
signed a treaty last month, committing to jointly restore the
Eel River and its fish populations. Leaders from the Round
Valley Indian Tribes in Mendocino County and the Yurok Tribe in
Del Norte and Humboldt counties met at the Eel River Canyon
Preserve in Trinity County last month to sign the “Treaty of
Friendship.” The agreement commits the tribes to restoring
the river and rebuilding its declining fish populations as
PG&E moves to decommission the Potter Valley Project
hydroelectric system’s Scott Dam in Mendocino County and Cape
Horn (also known as Van Arsdale) Dam in Lake County.
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.
