When wildfires scorch a landscape, the flames are just the
beginning. NASA is helping communities across the nation
foresee and prepare for what can follow: mudslides, flash
flooding, and contaminated surface water supplies. A new online
tool called HydroFlame, built with support from NASA’s Earth
Science Division, relies on satellite data, hydrologic
modeling, and artificial intelligence to predict how wildfires
could affect water resources, from tap water to the rivers and
streams where people fish.
The composition of fish populations in streams and rivers
across the U.S. has been severely altered as a result of
changing water temperatures and human-driven introductions of
fish, according to new research. Cold-water streams have
experienced disproportionate impacts, experiencing more than a
50% decrease in fish abundance over the last three decades,
according to a study published Wednesday in Nature. Some of the
largest threats include climate change and fish introductions
— both by invasive species or game fish stocking, scientists
say.
Ted Cooke, the former nominee for commissioner of the Bureau of
Reclamation, called the decision to scuttle his nomination
“feckless.” President Donald Trump had nominated Cooke, the
former director of the Central Arizona Project, in June to head
the bureau. … Cooke was an integral part of the
negotiations in the Colorado River’s 2019 Drought Contingency
Plan, an agreement among all seven Colorado River basin states
that aimed to protect water levels in Lake Mead and Lake
Powell. … Cooke’s nomination was greeted with applause
from the Lower Basin states, and a certain amount of skepticism
from the Upper Basin states.
The Stockton City Council voted to formally oppose the state of
California’s Delta Conveyance Project, known as the Delta
Tunnel, due to concerns about water quality and environmental
impacts. The city resolution states that the project would
degrade water quality for the Stockton region, threaten fish
and wildlife, increase harmful algae blooms, and increase
salinity intrusion in the Delta. … However, the
state says the project is needed to ensure the safety of
drinking water for millions of people.
Major construction on the Sunol Valley Fish Passage Project, an
effort intended to restore fish passage and ecological function
in the upper Alameda Creek, is expected to be completed this
year. The project involves the removal of an existing Sunol
Valley concrete erosion-control mat, which is protecting a
36-inch pipeline, L303, owned and operated by Pacific Gas and
Electric Company (PG&E). … Removal of this final
major barrier in the mainstem Alameda Creek was driven by
decades of work by the Alameda Creek Alliance and the Alameda
Creek Fisheries Restoration Workgroup to complete 16 other
fish-passage projects.
The Interior Department has stopped dozens of
environment-related grants to at least two nonprofit groups,
recipients said Wednesday. Interior agencies including the Fish
and Wildlife Service and Bureau of Land Management stunned two
organizations — California Trout and the
Institute for Applied Ecology — on Tuesday with the declaration
that their grants were canceled. California Trout has received
28 FWS grants since fiscal 2014, according to a federal
spending database. … All seven of California Trout’s
active grants were axed.
A conservation group on Wednesday formally petitioned for the
western spadefoot frog to receive protection under California’s
Endangered Species Act. The Center for Biological Diversity
petitioned for federal protection for two frog populations
separated by Southern California’s Transverse
Ranges. … The frogs depend on vernal pool
complexes, which are temporary wetlands connected to
upland grasslands or shrublands. Vernal pools are depressions
in a forest that hold water for part of each year, supporting
species like the western spadefoot. According to the
center, more than 90% of these pools have been lost to urban
development, intensive agriculture and roads.
I recently spoke with seventeen-year-old Keeya Wiki about the
first descent of the Klamath River, a 263-mile
river in Oregon and California. Keeya, who is Yurok and Māori,
was one of thirty youth who kayaked the river for the first
time in one hundred years. She reminded me of what it feels
like when you protect something sacred. In 2024, four dams came
down on the Klamath River, the largest dam removal in U.S.
history, and the river was free. The youth trained for the
descent on white waters throughout the region, and even in
Chile, to make sure they were safe. Then this summer they
joined the river and traveled for a month of freedom, joy, and
renewal.
As the San Diego City Council prepares to make major water rate
hikes, city staff clearly want weary councilmembers to blame
the San Diego County Water Authority and not the wastewater
recycling project the city is building. … On Friday,
city Public Utilities staff released a new cost analysis that
showed how Pure Water, a multi-billion-dollar wastewater
recycling project, could produce cheaper water than what the
San Diego County Water Authority provides. The city’s new Pure
Water numbers are the latest jab at the Water Authority over
growing water prices.
California is seeing a spike in cases valley fever — an illness
spread by fungal spores. Researchers speculate the
rise is tied to patterns of drought and
precipitation. … [Gail Sondermeyer Cooksey,
epidemiologist at the California Department of Public Health:]
When we see prolonged drought followed by heavy winter rains,
we see these surges in Valley Fever in the years that follow.
… There is a lot of concern that changes in climate and
environment are going to lead to these diseases occurring more
in the state of California, but also elsewhere in the United
States.
Following an extremely warm, dry summer on the Western Slope,
recent rainfall is beginning to chip away at the worst of
Colorado’s drought conditions. In mid-August,
“exceptional” drought conditions — the most severe among the
national drought monitor rankings — developed across nearly 7%
of the state in northwest Colorado for the first time since May
2023. … “Fortunately, the exceptional drought that we
had in early to mid-August is over in western Colorado with the
persistent rains of the last few weeks,” said Russ Schumacher,
Colorado’s state climatologist, at September’s Colorado Water
Conditions Monitoring Committee meeting on Tuesday.
The Department of Homeland Security issued a waiver Tuesday
allowing the federal government to bypass environmental laws in
order to fast-track construction of more barriers along the
U.S.-Mexico border in the San Diego area. … The waiver will
allow the federal government to bypass more than two dozen laws
including the Endangered Species Act, the Clean Water
Act and the Native American Graves Protection and
Repatriation Act. … Environmentalists and advocacy
groups say the waiver is inhumane and will further harm
migratory species and damage sensitive habitat.
Volunteers took to the Santa Ana River to clean up trash as
part of the 41st Annual California Coastal Cleanup
Day. More than 25 people joined to collect more than 145
pounds of trash during the Saturday, Sept. 20, effort at Martha
McLean-Anza Narrows Park in Riverside. The Santa Ana River
runs through the park. The event was organized by Caltrans and
the Inland Empire Waterkeeper and was one of hundreds across
the state that day at beaches, rivers, creeks, bays and
wetlands, a news release states.
Yuba Water Agency is set to increase the water flows on the
Yuba River below the New Bullards Bar Dam starting September
29. Officials say the change is part of the Colgate Tunnel and
Penstock Improvement Project. … Parker explained that
due to taking the powerhouse offline, the water flow will be
higher than normal. Yuba Water Agency urged local recreators to
avoid the area or exercise extreme caution. … Starting
Monday, the flow will increase to about 900 cubic feet per
second.
California’s largest drinking water supplier is trying to turn
the page. The Metropolitan Water District of Southern
California, which imports and sells water to 19 million people
in Los Angeles and the surroundings, earlier this month zeroed
in on Shivaji Deshmukh, the current general manager of the
Inland Empire Utilities Agency, to replace retiring General
Manager Deven Upadhyay. … The impending changeover comes
as the agency faces a series of pivotal decisions on how to
handle shrinking supplies and growing costs — and after years
of instability at the top of LA’s water world.
Colorado saw a record fiscal year in sports betting last year,
resulting in over $36 million in tax revenue after over $6.3
billion in bets were made, according to the Colorado Department
of Revenue. Of that, over $33 million will go to Colorado’s
Water Conservation Board, the department said. … About
93% of revenue from the tax on casinos helps fund the
implementation of Colorado’s water plan, according to Water for
Colorado, a coalition of nonprofits that work on water
conservation throughout the state. Water for Colorado calls the
agreement “a win for Colorado’s water.”
A new study, led by federal agencies in collaboration with the
University of Colorado Denver, shows that the whitebark pine
tree—an iconic, high-elevation tree that stretches from
California’s Sierra Nevada through the Cascades and
Rockies and into Canada—could lose as much as 80
percent of its habitat to climate change in the next 25 years.
… The threatened whitebark pine tree is a crucial food
source for squirrels and grizzly bears. It also acts as a
natural snow fence, holding snowpack in place
and releasing meltwater slowly throughout the summer. That
runoff supports entire watersheds, which
farmers and ranchers depend on.
… Once considered a relic of the 1930s Great Depression era,
dust storms are once again a growing challenge across the
western United States. … One contributor to these dust
events is the slow-motion drying of the massive inland lakes
across the western U.S. caused mainly by climate change and
intensive water use. Among them is Imperial Valley’s Salton
Sea. … Under pressure from intense water use and climate
change-fueled drought, the vast lake is steadily receding. …
[T]he Salton Sea is also laced with decades of agricultural
chemicals, pesticides and the remnants of military bomb testing
— which researchers have warned may be making it into the air
as well.
OpenAI is scouring the U.S. for sites to build a network of
huge data centers to power its artificial intelligence
technology, expanding beyond a flagship Texas location and
looking across 16 states to accelerate the Stargate project
championed by President Donald Trump. … The company’s
request for proposals calls for sites with “proximity to
necessary infrastructure including power and
water.” … Data centers also typically
draw in large amounts of water for cooling. … The other
states where OpenAI is actively looking include
Arizona,California, Florida,
Louisiana, Maryland, Nevada, New York, Ohio, Utah, Virginia,
Washington and West Virginia.
Many parts of the world are predicted to endure “day-zero
droughts,” periods of extreme and unprecedented water scarcity,
which could happen as soon as this decade in certain hotspots
including parts of North America, the Mediterranean and
southern Africa, according to a new study [in Nature
Communications]. … Day-zero droughts arise from the
confluence of various factors, including a prolonged dearth of
rain, low river levels and shrunken reservoirs, as well as
rocketing water demand to supply people, farms and industries.
… More than a third of these regions, including the
western United States, could face this situation as early as
the 2020s or 2030s.
