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.

Mexico has agreed to send water to the United States and
temporarily channel more water to the country from their shared
rivers, a concession that appeared to defuse a diplomatic
crisis sparked by yearslong shortages that left Mexico behind
on its treaty-bound contribution of water from the borderlands.
… In a social media post, Mr. Trump accused Mexico of
“stealing” water from Texas farmers by not meeting its
obligations under a 1944 treaty that mediates the distribution
of water from three rivers the two countries share: the
Rio Grande, the Colorado and the Tijuana. In an
agreement announced jointly by Mexico and the United States on
Monday, Mexico will immediately transfer some of its water
reserves and will give the country a larger share of the flow
of water from the Rio Grande through October.
The Federal Bureau of Reclamation is increasing the amount of
water available for Fresno County farmers through the Central
Valley Project dam and canal system. On Monday, the bureau said
it would boost the allocation for south-of-Delta water users,
including the Westlands Water District, to 50%, up from the 40%
announced in March. Acting California-Great Basin Regional
Director Adam Nickels said the increased allocation abides with
President Donald Trump’s executive order increasing water for
Central Valley farmers.
The Trump administration has dismissed the hundreds of
scientists and experts who had been compiling the federal
government’s flagship report on how global warming is affecting
the country. The move puts the future of the report, which is
required by Congress and is known as the National Climate
Assessment, into serious jeopardy, experts said. … Since
2000, the federal government has published a comprehensive look
every few years at how rising temperatures will affect human
health, agriculture, fisheries, water
supplies, transportation, energy production and other
aspects of the U.S. economy. The last climate assessment
came out in 2023 and is used by state and local governments as
well as private companies to help prepare for the effects of
heat waves, floods, droughts
and other climate-related calamities.
Despite pleas from leaders of regional farm bureaus, Lake
County and communities including Cloverdale and Lake Pillsbury,
President Donald Trump’s administration says it has no
intention of assuming control of the Potter Valley
hydroelectric power plant that’s slated for decommissioning by
PG&E. The decommissioning, if approved, is likely at least
a decade away and would involve tearing down the Cape Horn Dam
in Mendocino County and Scott Dam in Lake County. This would
alter the flow of the Eel River to the Russian River, with a
new multimillion-dollar diversion facility routing water from
both the Eel and Russian watersheds to Marin, Sonoma, Lake and
Mendocino counties. Many North Coast elected officials and
residents strongly oppose the plan, insisting it might not
provide the four counties with enough water ― especially during
dry, summer months punctuated by fire risk.
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.
