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.
In a much-needed break after multiple years of severe droughts
over the past two decades, California’s statewide Sierra Nevada
snowpack, which provides nearly one-third of the state’s water
supply, was at 96% of its historical average on Tuesday, up
from 83% a month before. The April 1 reading, considered the
most important of the year by water managers because it comes
at the end of the winter season, follows two previous years
when the snowpack reached 111% of normal on April 1 last year
and 237% in 2023. Although Tuesday fell just short of a third
year in a row above 100%, together the past three years
represent most bountiful three-year period for the Sierra
snowpack in 25 years. The last time there was this much snow
three years in a row came in 1998, 1999 and 2000.
California isn’t recycling nearly enough water, according to a
new report by UCLA researchers, who say the state should treat
and reuse more wastewater to help address the Colorado River’s
chronic shortages. Analyzing data for large sewage treatment
plants in seven states that rely on Colorado River water, the
researchers found California is recycling only 22% of its
treated wastewater. That’s far behind the country’s driest two
states: Nevada, which is recycling 85% of its wastewater, and
Arizona, which is reusing 52%. The report, based on 2022 data,
found other states in the Colorado River Basin are trailing,
with New Mexico recycling 18%, Colorado 3.6%, Wyoming 3.3% and
Utah less than 1%.
The first major development in Imperial County’s vaunted but
stalled Lithium Valley may have nothing to do with lithium.
Instead, a massive data server farm could replace hay fields on
a 315-acre patch along Highway 111 at West Sinclair Road, the
“gateway” to the proposed industrial zone in the Southern
California desert. CalETHOS president and chief operating
officer Joel Stone told The Desert Sun that the publicly traded
start-up aims to break ground on a 200,000-square-foot data
center by 2026. … Data centers, the physical backbone of
the Internet, are notorious for using huge amounts of
water and often polluting electricity. That
concerns some in a county dependent on the dwindling
Colorado River for all its water. … But
Stone said they want to build a cutting-edge campus that uses
the geothermal reserve for clean power and will require little
water.
… How best to get rid of PFASs is now a multibillion-dollar
question. The EPA estimated that US utilities might have to
spend up to $1.5 billion annually for treatment systems; an
industry group that is suing the agency argues that costs could
be up to $48 billion over the next 5 years. Utilities must have
systems in place by 2029. … And although the EPA has
focused on drinking water, scientists want to stop PFASs from
ever reaching the water by removing them from other
environmental sources. … With looming deadlines,
academic researchers and companies are developing methods to
gather and destroy PFASs from these sources.
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.
