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.
Time is running out to register for next week’s Water
101 Workshop and go beyond recent national headlines
to gain a deeper understanding of how water is managed and moved
across California. Plus, only a handful of spots remain for the
opportunity to extend your ‘beyond the headlines’ water education
experience on our Central Valley
Tour! And come one, come all to our annual Open
House & Reception on May 1.
Go beyond the stream of recent
national headlines and gain a deeper understanding of how water
is managed and moved across California during our Water
101 Workshop on April 10.
One of our most popular events, the daylong workshop at
McGeorge School of Law in Sacramento offers anyone new to
California water issues or newly elected to a water district
board — and really anyone who wants a refresher — a chance to
gain a solid statewide grounding on the state’s water
resources.
Some of state’s leading policy and legal experts are on the
agenda for the workshop that details
the historical, legal and political facets of water management in
the state.
California is only halfway through the rain year, and in
Redding’s case, the rainfall and snowfall amounts exceed what
the area typically receives in total precipitation, making 2025
one of the wettest years since 2019. …Wet winter storms
left waters in California’s largest reservoir,
Lake Shasta, less than 16 feet from the top on Tuesday.
Precipitation in March pushed the lake level more than 18 feet,
according to data from the California Department of Water
Resources, boosting the top almost as high as Shasta Dam was
after torrential rains in early February. It is expected the
lake may be full by end of May.
In a wide-ranging ruling that could have larger implications
for public interest lawsuits throughout California, the 5th
District Court of Appeal reversed a preliminary injunction that
had required water in the Kern River through the heart of
Bakersfield. … Bring Back the Kern, Water Audit California
and several other public interest groups sued the City of
Bakersfield in 2022 for dewatering the river. They are
demanding the city study the environmental impacts of its river
operations. That lawsuit is set for trial in December. The
preliminary injunction was an outgrowth of that 2022 lawsuit.
It was an attempt to keep water in the river for fish that had
come teeming back with high flows in 2023. The 5th
District’s ruling, issued Wednesday, reversed the injunction
but didn’t close the door to a possible future injunction and,
in fact, gave lengthy direction for how that could be done.
The Trump administration is considering rolling back a major
Biden-era regulation on “forever chemicals” in drinking water,
a move that could leave people more exposed to the substances
linked to cancer, high blood pressure and fertility problems.
But any attempt to weaken the rule would run into a formidable
statutory standard, experts say — the same one that has gotten
EPA into legal messes in the past. Finalized last spring, EPA’s
current rule requires water utilities to remove the man-made
chemicals from drinking water starting in four years. Formally
called per-and polyfluoroalkyl substances or PFAS, “forever
chemicals” are known for their virtual indestructibility and
have been found in approximately half the nation’s tap water.

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.
