… The Colorado River Basin is in dire straits: The water
supply for 40 million people has been dwindling, and
climatologists say the climate future is bleak. State officials
have spent months mired in thorny negotiations over things like
how to split painful water cuts in the driest conditions — with
scant progress to report publicly. … The final plan
could determine everything from how key reservoirs store and
release water to who takes cuts in dry years and how
environments, like the Grand Canyon, will be impacted for years
to come. It will impact water supplies for cities, like Denver,
Phoenix and Los Angeles, ecosystems, a multibillion-dollar
agricultural industry, hydroelectric power and more.
In California’s water wars, fishermen and farmers have long
been enemies. But now that federal and state regulators have
closed the salmon commercial fishing season for an
unprecedented third year in a row to protect declining
populations, at least one major commercial fishing group is
shifting its alliances. The Pacific Coast Federation of
Fishermen’s Associations teamed up with farmers for a
first-ever joint Washington, D.C., lobbying trip in early May.
They met with members of Congress and federal officials to ask
for more money for salmon hatcheries, which breed, raise and
release young fish. … For the Fishermen’s Associations, which
have sued for decades to keep water in California’s rivers for
fish instead of being diverted to farmers, the trip is part of
a larger pivot amid growing desperation as high temperatures
and low water levels kill their business.
More than 100 residents in the tiny unincorporated town of West
Goshen can weather the summer months knowing that by the end of
it, the water flowing through their faucets will be safe for
drinking, cooking and bathing thanks to a new connection to
California Water Service. Residents along with local and state
officials marked that monumental step at a groundbreaking
ceremony Thursday evening in West Goshen, west of Visalia and
Highway 99 in Tulare County. … California Water Service
provides water to Visalia residents. It was able to connect
West Goshen through an emergency consolidation project. West
Goshen residents had relied for years on bottled water after
they discovered groundwater from private wells was laced with
uranium, nitrates and other contaminants. The 60-day
connection project will require a crew of eight to lay more
than 8,000 feet of pipe.
… (T)hings only got worse on May 30, when the Trump
administration’s fiscal year 2026 budget request for NASA came
out. It proposes cutting the agency’s science funding by 47%,
and the agency’s workforce by about one-third — from 17,391 to
11,853. … According to the Planetary Society’s analysis
of the budget, that huge astrophysics reduction could mean
eight spacecraft dedicated to studying extreme events in the
universe (think, the Chandra X-ray Observatory) would be
terminated. This analysis also suggests 10 missions constructed
to study the region around Earth and the sun would be
cancelled, as well as about a dozen Earth-specific missions
that help scientists forecast natural disasters such as
hurricanes and track global
warming. … Per the budget proposal, the
White House also wants NASA to eliminate its “green aviation”
spending, dedicated to making airplanes better for the
environment, and instead work on “protecting the development of
technologies with air traffic control and defense
applications.”
One new legal filing and a raft of letters have been sent to
the California State Supreme Court alternately praising and
decrying the recent 5th District Court of Appeal opinion that
overturned a local court order that had kept the Kern River
flowing, at least for a few months. The response, filed by
several agricultural water districts with Kern River rights,
urges the Supreme Court to deny a petition to review the 5th
District’s opinion and let it remain published, which can set
precedent for how other courts rule in similar cases. The
letters all seek to have the Supreme Court “depublish” the 5th
District’s ruling, making it less potent. Two of the letters
were filed by the original plaintiffs. … The state Attorney
General and two environmental public interest groups also sent
letters beseeching the state’s top court to depublish the 5th
District’s opinion.
… Last year, the final of four hydroelectric dams on the
Klamath River were removed in the largest project of its kind
in US history. Forged through the footprint of reservoirs that
kept parts of the Klamath submerged for more than a century,
the river that straddles the California-Oregon border has since
been reborn. The dam removal marked the end of a
decades-long campaign led by the Yurok, Karuk and Klamath
tribes, along with a wide range of environmental NGOs and
fishing advocacy groups, to convince owner PacifiCorp to let go
of the ageing infrastructure. The immense undertaking also
required buy-in from regulatory agencies, state and local
governments, businesses and the communities that used to live
along the shores of the bygone lakes. As the flows were
released and the river found its way back to itself, a new
chapter of recovery – complete with new challenges – emerged.
A new science brief published today by Audubon California shows
that a number of factors have surprisingly resulted in an
increase in wetland habitat, and that an increasing number of
shorebirds are taking advantage of the changes—driving a growth
rate of 15 percent per year in waterbirds overall. This new
development comes as the Sea continues to witness the shrinkage
of deep-water habitats and fish-eating bird
populations. This finding and others are drawn from seven
years of Audubon’s bird surveys and habitat assessments at the
Salton Sea. … The science brief, which summarizes a
more comprehensive scientific study currently under peer review
in a scientific journal, points to significant shifts in
habitats, food availability, and bird populations. Newly formed
vegetated wetlands, for example, increased from 5,944 acres in
2019 to 7,312 acres in 2022, or by 23 percent.
The Navajo Nation Commission on Emergency Management (CEM)
unanimously approved Resolution No. 25-005, officially
declaring a State of Emergency in response to worsening drought
conditions across the Nation. All six commissioners voted in
favor of the resolution. … Resolution 25-005 addresses a
range of urgent concerns, including critically low
precipitation, deteriorating rangelands, declining water
infrastructure, and heightened wildfire risks. The declaration
calls on livestock owners to reduce herd sizes, instructs
Grazing Officials to update tally counts, and encourages
farmers to shift to drought-resistant crops. It also places
restrictions on irrigation to conserve dwindling lake and
reservoir supplies. … The resolution authorizes
$6,553,730 from the Agricultural Infrastructure Fund (AIF) to
be directed toward critical repairs to windmills and the
installation of water storage systems in drought-affected
communities.
Water scarcity, population growth and climate change are on a
collision course in the American West. That’s clear in cities
like St. George, a desert community surrounded by stunning red
rock cliffs and mesas in Utah’s southwest corner. The
population is booming and climate change is making heat more
intense and rain less reliable. But local leaders have a plan
to stretch the area’s water supply by turning to its sewage — a
solution that could help other drought-stricken cities,
too. … Reusing water that would have otherwise flowed
downstream to Lake Mead — the nation’s largest reservoir — is
the centerpiece of the district’s long-term water plan. But it
will come at a steep cost: over a billion dollars. … St.
George’s quandary is a microcosm of the challenges cities face
across the Western U.S. as overuse and drought strain the
Colorado River and the basin’s seven states fight over how the
river’s water gets distributed in the future.
The vastly different viewpoints around whether or not the
Potter Valley Project should be decommissioned — and dismantled
— took center stage at a special event in Lakeport at the end
of May. The Lake County Chamber of Commerce hosted the Lake
Pillsbury and Potter Valley Project town hall on the evening of
Wednesday, May 28, at the Soper Reese Theater in Lakeport. The
Potter Valley Project includes the Potter Valley powerhouse,
Cape Horn Dam and Van Arsdale Reservoir, Scott Dam and Lake
Pillsbury. Pacific Gas and Electric Co. has operated the
project for decades but in 2019 the corporation abandoned its
license for the hydroelectric facility after determining it was
“uneconomic” for its customers to maintain. The negotiations
about the future of the project, and in particular Lake
Pillsbury — located in northern Lake County — have seen Lake
County largely sidelined by larger regional and political
interests.
On the afternoon of May 22, a wildfire sparked next to Highway
395 near the Mono Lake Tufa State Natural Reserve in the
Eastern Sierra Nevada, causing major damage to the reserve’s
infrastructure. The Inn Fire took off quickly, fueled by
high and erratic winds that caused it to jump across the
highway, where flames burned into the reserve.
… Officials are still assessing the extent of the damage
caused by the Inn Fire. One home burned down soon after the
fire ignited, and flames destroyed vegetation in the Inyo
National Forest, burning up toward the mountains. In the state
reserve, Jackson said flames burned into protected wetland
habitat and around the tufas. But the tufas are undamaged, she
noted. … The California State Parks Sierra District is
working with local land managers and other partners to plan how
to rebuild the boardwalk and the interpretative signs that were
lost in the fire.
On May 29, 2025, the U.S. Supreme Court issued an 8-0 opinion
that clarifies the scope of environmental effects analysis
under the National Environmental Policy Act (NEPA) and requires
substantial judicial deference to federal agencies in NEPA
cases. This decision has broad implications for public agencies
and Tribal Nations involved in infrastructure and economic
development projects, natural resources management, water
supply project operations and other matters where there is a
federal nexus. … For local communities, water agencies,
and Tribal Nations with projects that depend on the NEPA
process, this ruling offers a couple of key takeaways. The
first is straightforward. The scope of environmental effects
analyzed in an EIS will continue to be limited by the authority
of the federal agency. … A more complex implication
relates to judicial deference—particularly deference to a
federal agency’s choice of alternatives and its feasibility
analysis.
The State Lands Commission of California has carried out the
largest-ever cleanup of abandoned commercial vessels at a
single site in its history. The operation took place at the
Sevenmile Slough area in the Sacramento-San Joaquin Delta, at a
location locally known as the Skarry site. This stretch of
water had been heavily affected by rotting, abandoned vessels
for years. For decades, abandoned vessels have been a
persistent issue across California’s waterways. However, the
problem has been especially severe in the Delta region. The
Commission said that the site contained several large and
deteriorating vessels that had remained untouched in the water,
continuing to break down and causing concerns for public safety
and the environment. … Workers cleared nearly 1,000 tons
of debris from the Delta. They also found and removed more than
1,000 gallons of diesel fuel from one of the largest crane
barges.
Richmond agreed to pay a $336,000 fine after it was found to
have released poorly treated sewage water into the San
Francisco Bay for more than a year. Half of that money will go
toward environmental education for children. Between July 31,
2022, and Dec. 31, 2023, inadequately treated wastewater was
released 112 times from the Richmond Municipal Sewer District
Water Pollution Control Plant at 601 Canal Blvd., the San
Francisco Bay Regional Water District announced Friday. Each
violation cost the city $3,000, according to a settlement
agreement between the city and water district. Richmond’s water
pollution control plant is responsible for reducing the amount
of harmful chemicals and pollutants flushed down toilets and
dumped in the drains of Richmond homes, businesses and
industrial operations before flowing into the San Francisco
Bay.
Gov. Gavin Newsom is up to his old tricks, trying to ram major
policy change through the state Legislature on short notice.
And again lawmakers are pushing back. Not only lawmakers, but
the Legislature’s nonpartisan, independent chief policy
analyst. The Legislative Analyst‘s Office has recommended that
legislators hold off voting on what the governor seeks because
they’re being pressed to act without enough time to properly
study the complex matter. Newsom is asking the Legislature to
“fast-track” construction of his controversial and costly water
tunnel project in the Sacramento-San Joaquin River
Delta. … Delta towns and farmers, environmental groups
and the coastal salmon fishing industry are fighting the
project and the governor’s latest move to expedite
construction. If there are any supporters at the state Capitol
outside the governor’s office for his fast-track proposal,
they’re not speaking up. –Written by Capitol Journal columnist George Skelton.
Facing its largest seasonal algal bloom in 20 years, the
Sweetwater Authority may need to buy water to address the
problem. At its May 28 board meeting, the South Bay agency
agreed to increase its budget for the year in case it must
purchase more water to dilute the water supply. The agency says
doing so would help mitigate changes to the water’s taste and
odor caused by the algae. … For the past six months
Sweetwater has been grappling with a number of pollutants in
its main reservoir and has been using its water surplus to
dilute the problem. Earlier this year, the authority
transferred water to the Sweetwater Reservoir from Loveland
Reservoir to lower levels of chemicals, known as PFAS, detected
in the water. Now, in what they say is a separate issue,
the agency would either use purchased water to dilute the algal
bloom, or may also sell the purchased water to customers rather
than diluting its own.
… (Bruce) Rittmann leads the Swette Center for Environmental
Biotechnology in ASU’s Biodesign Institute. For more than 20
years at ASU, Rittmann has been creating and refining a
technology that uses microbes like bacteria to remove harmful
substances from water. The technology is called membrane
biofilm reactor, or MBfR. … His team developed the
membrane catalyst-film reactor, or MCfR, to support the
bacteria in the MBfR. The MCfR uses a metal called palladium to
break the fluorine bonds in the chain. This step allows the
microbes to finish the job of turning harmful PFAS into its
harmless components. Rittmann says the combined MBfR and MCfR
system works on the top six PFAS chemicals targeted by the EPA
in drinking water. It can also work on others that are of
concern to environmental and human health.
Negotiations over a new operating plan for the Colorado River
are being hobbled by the federal government’s failure to take a
more aggressive role in the discussions, said current and
former state and federal officials Thursday. The critiques came
from a cadre of former water managers who took part in previous
deals on the waterway under both Democratic and Republican
administrations, speaking during the annual 45th Annual
Colorado Law Conference on Natural Resources at the University
of Colorado. “The current process kind of feels like the
conclave,” said Jim Lochhead, the former CEO of Denver Water
and former executive director of the Colorado Department of
Natural Resources, referring to the process of electing a new
Catholic pope. “We’re waiting for the black smoke or the white
smoke to come out of the seven-state negotiating meeting.”
After a two-year shutdown, fishing boats will fan out along the
California coast angling for Chinook salmon this weekend as
recreational fishing resumes under strict limits. Coastal
salmon fishing was banned in 2023 and 2024 in an effort to help
the population recover after years of declines. … The
California Department of Fish and Wildlife is limiting ocean
fishing under quotas in two windows in the summer and fall. The
first is set to open Saturday-Sunday and allow for up to 7,000
salmon to be caught statewide. … Biologists say salmon
populations have declined because of a combination of factors
including dams, which have blocked off spawning areas, the loss
of vital floodplain habitats, and global warming, which is
intensifying droughts and causing warmer temperatures in
rivers. … Those who work in fishing also blame California’s
water managers and policies, saying too much water has been
pumped to farms and cities, depriving rivers of sufficient cold
water at the times salmon need it.
An invasive species of mussels first discovered in the Port of
Stockton is now getting attention in Washington, D.C. Rep. Josh
Harder, D-Tracy, said this week he has joined other Delta-area
members of Congress in introducing a bill aimed at trying to
halt the spread of golden mussels. The mollusks have been found
in various parts of the Delta and as far south as Bakersfield.
The discoveries have prompted a variety of measures, including
closure of at least one popular San Joaquin County reservoir to
the launching of boats, kayaks and other watercraft. Perhaps
most alarming, officials at Lake Tahoe say their inspectors
found a boat that the owner had hoped to launch that was
encrusted with golden mussels. … Harder said the
bill that was introduced will protect Delta and
waterways by initiating a rapid response program to
contain and eradicate infestations. It also will fund new
technology and inspection stations and foster coordination
between local, state and federal agencies.
