Southern California’s Salton Sea—approximately 232 feet (70 m)
below sea level— is one of the world’s largest inland seas. It
has 130 miles of shoreline and is larger than Lake Tahoe.
The sea was created in 1905 when the Colorado River broke through
a series of dikes, flooding a salty basin known as the Salton
Sink in the Imperial Valley. The sea is an important stopping
point for 1 million migratory waterfowl, and serves as critical
habitat for birds moving south to Mexico and Central America.
Overall, the Salton Sea harbors more than 270 species of birds
including ducks, geese, cormorants and pelicans.
At the Salton Sea’s western edge, near Salton City, the efforts
of the Salton Sea Management Program are starting to show
promise. But as the western side of the lake begins to
stabilize, a different story is unfolding at Bombay Beach on
the eastern shore. At the Clubhouse Site of the SSMP’s
Vegetation Enhancement Project just outside of Salton City,
grass bales laid out across acres of exposed lakebed have begun
to serve their intended purpose. Vegetation is now sprouting
between them and slowly covering the dusty landscape. This
success has fueled optimism among SSMP officials, who believe
they are seeing the kind of progress needed to combat the dust
storms and environmental degradation that have plagued the area
for years.
The California Legislature has passed and sent to Gov. Gavin
Newsom a bill to create the Salton Sea Conservancy to lead
multi-million-dollar efforts to restore the shrinking and
increasingly toxic inland sea. The new conservancy would be the
state’s 11th and the first established in over 15 years. The
goal would be to protect residents’ health, foster ecological
recovery of the area, and empower local stakeholders.
… The Salton Sea formed in 1905 after overflow from the
Colorado River spilled into a basin in the desert, creating the
largest lake in California. Over the past several decades,
evaporation exacerbated by droughts has reduced the sea,
exposing a toxic lake bed.
Six years after breaking ground, progress at the Salton Sea
Management Project is rapidly accelerating. Now, as the
initiative gathers momentum, a vast reclamation of lost habitat
begins to emerge. In the dusty landscape at the south end of
the Salton Sea, the SSMP is hard at work building the Species
Conservation Habitat, one of the largest conservation
engineering projects in the country. The Salton Sea has been
receding rapidly, exposing more of the lakebed, sending more
dust into the air and removing thousands of acres of habitat
for the many species that call this desert home. In 2018, the
SSMP began its 10-year project to replace 30,000 acres of lost
habitat, and now, six years into this ambitious effort, the
work is beginning to bear fruit.
… Something in the environment — in the water, the land, the
air, or all three — appears to be making people in the region
sick with a respiratory disease that presents like asthma. …
And although residents of the area have long believed the
Salton Sea to be toxic, … researchers at UC Riverside are
only now beginning to zero in on a culprit. And it’s one that
nobody expected. The Salton Sea, the largest lake in California
by surface area, has been drying up in recent years, the result
of drought and water management decisions on the Colorado River
and in the Imperial and Coachella valleys, whose agricultural
runoff feeds the lake. … Scientists have long
understood there to be a connection between the dust and the
region’s poor respiratory health. But after years of research,
recent findings have offered surprising new insights: The prime
suspect now is a naturally occurring toxin, embedded in the
dust. The discovery holds far-ranging implications — not only
for the Salton Sea, but for other drying lake systems around
the world.
The air quality is notoriously bad near the Salton Sea. As
California’s largest lake has continued to evaporate, it’s
become saltier and dustier, causing breathing problems for
locals like Clark. Alongside the health problems is what she
describes as a “putrid dead smell” emanating constantly from
the water. A soon-to-be published study by UC Riverside shows
that the Salton Sea’s rotting odors have become a yearlong
nuisance for residents in cities near the lake. The South Coast
Air Quality Management District recently issued another odor
advisory for parts of the Coachella Valley just north of the
Salton Sea, a warning that covered the last six days.
People living near California’s Salton Sea were used to
experiencing unpleasant odors coming off the lake in the late
summer. But now, according to new research, that smell seems to
be blanketing the area for almost half the year. The
stench, caused by high hydrogen sulfide levels that emanate
from the decaying, rapidly shrinking sea, has been
detected in higher frequency for as many as five or six months
per year as opposed to just once a year, according to a new
study from UC Riverside that was first reported on by
the Palm Springs Desert Sun.
Humidity, hot winds and the decaying Salton Sea have long been
been a recipe for nostril and stomach misery during the summer
across large swaths of the eastern Coachella Valley. But now,
an analysis of 20 years worth of records by a UC Riverside
laboratory shows a disturbing new trend: The noxious odor is
hanging around at detectable lower levels year-round.
… Since Friday, hydrogen sulfide levels have repeatedly
exceeded the state recommended level of 30 parts per billion
average per hour, in some cases more than double that
recommended limit. Air regulators issued an extended odor
advisory for the eastern Coachella Valley through Wednesday
evening, citing shifting winds off the Salton Sea.

The Layperson’s Guide to the Colorado River Basin introduces the
1,450-mile river that sustains 40 million people and millions of
acres of farmland spanning seven states and parts of northern
Mexico.
The 28-page primer explains how the river’s water is shared and
managed as the Southwest transitions to a hotter and drier
climate.
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

For more than 20 years, Tanya
Trujillo has been immersed in the many challenges of the Colorado
River, the drought-stressed lifeline for 40 million people from
Denver to Los Angeles and the source of irrigation water for more
than 5 million acres of winter lettuce, supermarket melons and
other crops.
Trujillo has experience working in both the Upper and Lower
Basins of the Colorado River, basins that split the river’s water
evenly but are sometimes at odds with each other. She was a
lawyer for the state of New Mexico, one of four states in the
Upper Colorado River Basin, when key operating guidelines for
sharing shortages on the river were negotiated in 2007. She later
worked as executive director for the Colorado River Board of
California, exposing her to the different perspectives and
challenges facing California and the other states in the river’s
Lower Basin.
State work to improve wildlife habitat and tamp down dust at California’s ailing Salton Sea is finally moving forward. Now the sea may be on the verge of getting the vital ingredient needed to supercharge those restoration efforts – money.
The shrinking desert lake has long been a trouble spot beset by rising salinity and unhealthy, lung-irritating dust blowing from its increasingly exposed bed. It shadows discussions of how to address the Colorado River’s two-decade-long drought because of its connection to the system. The lake is a festering health hazard to nearby residents, many of them impoverished, who struggle with elevated asthma risk as dust rises from the sea’s receding shoreline.
Out of sight and out of mind to most
people, the Salton Sea in California’s far southeast corner has
challenged policymakers and local agencies alike to save the
desert lake from becoming a fetid, hyper-saline water body
inhospitable to wildlife and surrounded by clouds of choking
dust.
The sea’s problems stretch beyond its boundaries in Imperial and
Riverside counties and threaten to undermine multistate
management of the Colorado River. A 2019 Drought Contingency Plan for the
Lower Colorado River Basin was briefly stalled when the Imperial
Irrigation District, holding the river’s largest water
allocation, balked at participating in the plan because, the
district said, it ignored the problems of the Salton Sea.
This event explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.

Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.
Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
For the bulk of her career, Jayne
Harkins has devoted her energy to issues associated with the
management of the Colorado River, both with the U.S. Bureau of
Reclamation and with the Colorado River Commission of Nevada.
Now her career is taking a different direction. Harkins, 58, was
appointed by President Trump last August to take the helm of the
United States section of the U.S.-Mexico agency that oversees
myriad water matters between the two countries as they seek to
sustainably manage the supply and water quality of the Colorado
River, including its once-thriving Delta in Mexico, and other
rivers the two countries share. She is the first woman to be
named the U.S. Commissioner of the International Boundary and
Water Commission for either the United States or Mexico in the
commission’s 129-year history.

California voters may experience a sense of déjà vu this year when they are asked twice in the same year to consider water bonds — one in June, the other headed to the November ballot.
Both tackle a variety of water issues, from helping disadvantaged communities get clean drinking water to making flood management improvements. But they avoid more controversial proposals, such as new surface storage, and they propose to do some very different things to appeal to different constituencies.

Scientifically and legislatively, lakes are indistinguishable
from
ponds, but lakes generally are considered to be longer and
deeper lentic, or still, waters. In the 18th and
19th centuries, scientists attempted to distinguish
the two more formally, stating that ponds were shallow enough to
allow sunlight to penetrate to the bottom, but this exists
today as an unofficial point.
Fearing an imminent public health threat, the director of the
University of California, Irvine’s Salton Sea Initiative said the
State Water Resources Control Board should step in and regulate
the rate of water transferred from the Imperial Valley to coastal
California as part of the Quantification Settlement Agreement.
The shallow, briny inland lake at the southeastern edge of
California is slowly evaporating and becoming more saline –
threatening the habitat for fish and birds and worsening air
quality as dust from the dry lakebed is whipped by the constant
winds.

Our 24×36-inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
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.
The Pacific Flyway is one of four
major North American migration routes for birds, especially
waterbirds, and stretches from Alaska in the north
to Patagonia in South America.
Each year, birds follow ancestral patterns as they travel the
flyway on their annual north-south migration. Along the way, they
need stopover sites such as wetlands with suitable habitat and
food supplies. In California, 95 percent of historic
wetlands have been lost, yet the Central Valley hosts some of the
world’s largest populations of wintering birds.
The Imperial Valley in the
southeastern corner of California receives the Colorado River
Basin’s single-largest share of water to support much of the
nation’s fruit and vegetable supply and hay for the
cattle and dairy industries.
Water from the Colorado River transformed the sagebrush and
desert sands of the Imperial, Coachella and Palo Verde valleys
into lush, green agricultural fields. The growing season is
year-round, the water plentiful and the local economies are based
almost entirely on farming. As the waters of the Colorado River
allowed the deserts to bloom, they allowed southern California
cities like Los Angeles and San Diego to boom. Suburbs, jobs and
people followed, and the population within the six counties
served by Metropolitan Water District of Southern California
(MWD) grew from 2.8 million in 1930 to more than 17 million
today.
