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.
Since 1977, the Water Education
Foundation has worked to inspire better understanding
and catalyze critical conversations about our most vital
natural resource: water.
This is not a mission our nonprofit can carry out alone.

The federal government is limiting which bodies of water are
eligible for protection under the Clean Water
Act. Now, Colorado is working on its own set of rules
for places that will no longer be federally protected,
following a 2024 bipartisan law. … The Sackett
ruling, along with the new proposal to only protect permanent
rivers and wetlands directly connected to them, poses a problem
for Colorado and other Mountain West states. Because of the
region’s reliance on snowmelt for much of its water supply,
bodies of water are often ephemeral, or intermittent.
… The Tahoe-Reno Industrial Center has a sprawling
landmass greater than the city of Denver. It is home to the
largest data center in the US, built by the company Switch. …
The Truckee River supplies the industrial center with water and
also serves as the primary source of water for Pyramid
Lake. … And as data centers continue to proliferate
in water-stressed areas around the globe, which can offer cheap
land and energy as well as low humidity for easier chip
cooling, one of the central concerns in local communities is
what happens if the water runs dry.
A federal district court in California failed to consider
impacts to other endangered species before
ordering San Luis Obispo County to develop a flow and release
plan for local steelhead trout, a federal appeals court ruled
Wednesday. The injunction blocking the Lopez Dam expansion “may
benefit one protected species at the expense of other protected
species,” and the US District Court for the Central District of
California didn’t consider this factor or the public interest,
the US Court of Appeals for the Ninth Circuit said.
… The Tribal Council of the Colorado River Indian Tribes
decided to recognize the river as a legal person under tribal
law. It’s the second time a Native tribe has declared legal
personhood for a river in the United States. The Yurok Tribe in
Northern California in 2019 declared the Klamath River a legal
person. I was interested to learn more about why the leaders of
the Colorado River Indian Tribes, or CRIT, wanted to take this
step, and Chairwoman Amelia Flores agreed to talk with
me.
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.
