Unable to get Colorado River states to hash out a new 20-year
deal to share in worsening water shortages, the U.S. Bureau of
Reclamation has told them it’s now aiming for a 10-year
plan with prescribed cutbacks to be reassessed every two
years. Federal officials informed the seven states of
their new preference late last week, and Arizona’s lead
negotiator made it public on Wednesday, May 13, during a
meeting of a committee representing the cities, tribes and
other water users who meet to develop a unified state position.
The shift to what could effectively become five two-year plans
carries both opportunities and risks for Arizona.
A bipartisan group of lawmakers wants to create a new tax
credit for water recycling projects in a bid to reduce
water use from industrial facilities and artificial
intelligence data centers. Sens. Ben Ray Luján
(D-N.M.) and Katie Britt (R-Ala.) on Wednesday introduced the
“Advancing Water Reuse Act.” The bill would offer companies
a 30 percent investment tax credit for
installing or expanding water recycling systems at
manufacturing sites, including food processing facilities and
data centers. Water recycling or reuse refers to efforts to
treat wastewater so that it can be used again for industry,
irrigation or drinking. The idea is gaining steam across the
nation, especially in the arid West and in
places seeing a resurgence in manufacturing or a growing number
of data center projects.
Seven years ago, California Gov. Gavin Newsom signed a law to
bring safe and affordable drinking water to the state’s most
disadvantaged communities. Last week, Newsom celebrated
the program’s accomplishments. … But that work could
lose critical funding as the Newsom administration overhauls
its source: California’s carbon market. The changes to
the program’s funding priorities and revenue threaten efforts
to bring clean drinking water to schools, homes and communities
across California. … The cuts began in
September, when Newsom and lawmakers struck a deal to
reauthorize the state’s carbon market after weeks of tense and
chaotic negotiations — renaming it “cap and invest.” The
new laws deprioritized funding lawmakers had promised to safe
drinking water.
From farmers to winemakers, commercial water users pumping from
the Paso Robles Area Groundwater Basin may soon need to pay for
their water use — and this time, they won’t be able to protest
the fees. On Friday, the Paso Robles Area Groundwater Authority
released a draft rate study that proposed charging
$22.90 per acre-foot of groundwater used by water
systems, farmers and commercial pumpers. … Meanwhile,
domestic well owners would not be charged water use fees, the
report said. The city of Paso Robles is the largest water
system that would pay fees, but this wouldn’t impact the city’s
ratepayers, Mayor John Hamon told The Tribune.
The Water Education Foundation’s 2025 Annual
Report is now available in an interactive,
digital format and recaps how we accomplished a lot of “firsts”
last year. A standout moment was our first-ever Klamath
Basin River Tour, where we brought 45 participants
into the heart of the watershed that underwent the nation’s
largest dam removal project. In 2025, the Foundation also
elected, for the first time, a graduate of our
California Water Leaders program to serve as Board
President – Alfred E. Smith
II. Check out our
2025 Annual Report to learn more about our
accomplishments and to find out which journalist received the

Rainfall across much of California and the West has become more
clustered in heavier storms, with longer dry spells in between.
The net effect is a drying out, researchers found in a new
study. It isn’t just the western United States; the same is
true in much of the rest of the world. The research is
the first to reveal how this concentration of rainfall into
fewer, heavier events dries out the landscape.
… The trend is less clear in Southern California and
more pronounced in the North. The America West is one of the
places where rainfall has become most clustered or
concentrated. The analysis, published Wednesday in the journal
Nature, offers new insight into how rainfall is shifting as the
climate warms.
The Trump administration will release $47 million in
long-awaited federal funding for four Colorado water projects
aiming to fight the Colorado River Basin’s prolonged drought.
The Biden administration promised Coloradans up to $152 million
in January 2025 to restore ecosystems, repair
infrastructure and address drought impacts. The Trump
administration immediately froze the grants pending review.
… This week’s announcement is the latest in a slow
trickle of released funding from the federal agency. In
addition to $25.6 million for the southwestern Colorado water
projects, the Bureau of Reclamation also released $4.6 million
for wetland restoration, floodplain improvements, erosion
control and more on conserved lands in western Colorado.
Yesterday, the Klamath National Forest released the final snow
surveys of the season which found that snowpack in the Scott
River watershed had almost entirely disappeared by May 1. State
and federal water officials have described this year’s snowpack
conditions as among the worst California has seen in modern
recordkeeping. According to the U.S. Forest Service, snow depth
and snow water equivalent — the amount of water stored in the
snowpack — measured just 0.8% of historical average.
… The findings mirror statewide trends documented this
spring. The California Department of Water Resources announced
on April 1 that surveyors found “no measurable snow” during the
critical Phillips Station snow survey in the Sierra Nevada
after what officials described as a record-hot and
exceptionally dry March.
Golden mussels may be small, but experts say they could create
major problems for California’s water systems, prompting urgent
warnings to local water agencies across Kern County.
… Local water agencies, engineers, and industry leaders
gathered on Wednesday to learn more about the invasive species
and possible mitigation efforts. Experts say the mussels were
first discovered in California’s Delta in 2024 and are believed
to have arrived from Asia on ships. They say the species
reproduces quickly. … Experts say preventing the spread
of golden mussels will also depend on the public, especially
boaters, by making sure boats and equipment are properly
cleaned, drained, and dried before entering another waterway.
In the wake of one of the hottest, driest winters on record,
communities in the Roaring Fork Valley are bracing for summer
with more-severe water restrictions, fines for the worst
offenders and a water conservation outreach campaign. At its
regular meeting Tuesday, Aspen City Council approved staff’s
recommendation of moving to a Stage 3 Water Shortage in a 4-1
vote. The city had been in Stage 2 since September. Stage 3
restricts outdoor irrigation to just two days a week: Tuesday
and Friday for even addresses; Wednesday and Saturday for odd
addresses; and no watering at all on Mondays, Thursdays or
Sundays.
Sustainable food and water policy leader Paula Daniels was
seated Tuesday as the City of Los Angeles’ newest
representative on the board of directors of the Metropolitan
Water District of Southern California. Daniels has spent more
than two decades working to advance public policy on food
systems and sustainability in the government, academic and
non-profit sectors. She is currently the inaugural executive
director of the Los Angeles County Office of Food Systems, a
partnership between the County of Los Angeles and local
philanthropic organizations to build a fair, resilient and
healthy food system for residents. Daniels is also co-founder
of the Center for Good Food Purchasing, which aims to guide how
public institutions purchase food to support sustainability,
equity and transparency.
In a clear sign that California is not facing water shortages
or a drought this summer, Lake Oroville, the state’s
second-largest reservoir and a key component of California’s
water system, has nearly filled to the top. The massive
reservoir, contained behind America’s tallest dam, was 99% full
on Tuesday afternoon, at 122% of its historical average for
mid-May and still slowly rising, with just two feet to go to
fill entirely. … The water from Oroville and the State
Water Project is sent hundreds of miles to cities and farms
across the state, serving 27 million people from San
Jose to San Diego. … The very low snowpack
[this year, however] means that as Oroville and other massive
reservoirs are slowly drawn down … they won’t be topped up in
the coming months by melting snow. So although this year’s
reservoir levels are good news, experts say, another wet winter
will be needed next year because by this fall,
reservoir levels may be lower than normal.
An environmental organization is floating a concept that could
help the Colorado River system during extremely dry years like
this one and keep the nation’s two largest reservoirs above
critical thresholds. Boulder-based Western Resource Advocates
has released a concept paper that explores the idea
of a flexible pool of water that can be moved wherever it’s
needed most among the basin’s biggest reservoirs. Water
users in the Lower Basin states — California, Arizona
and Nevada — currently have about 3.2 million
acre-feet stored in Lake Mead through voluntary conservation
and efficiency measures. Water users bank water in this
pool, known as the Intentionally Created Surplus, and can take
this water back out again to use under certain
circumstances.
Tucson leaders unanimously rejected a massive data center
dubbed Project Blue last year amid outcry from the community
with concerns about water, power and resources
that they didn’t want put toward a data center. It was a heated
moment that came to a head during an August council meeting.
But despite that vote, the project is still being built.
Developer Beale Infrastructure got the zoning they needed from
Pima County instead and announced they would build the data
center to be air-cooled instead of
water-cooled. But now Tucson says a contractor working
on the construction of Project Blue has been using Tucson water
anyway and they’ve revoked their permit to do it.
… As utilities cope with weather extremes by scrambling to
repair their infrastructure and tapping new water sources, the
cost is beginning to show up in residents’ bills. Between 1998
and 2020, the average cost of water, sewer and trash collection
services increased more than twice as much as the overall U.S.
consumer price index. … Longer and more intense
droughts have triggered restrictions on water use from Florida
to Colorado. … Water has long been one of the most
affordable utility bills for American households. … But
climate change is increasingly battering utilities with weather
— and costs — they did not plan for. … Amid a
decades-long megadrought that has diminished aquifers and
caused a catastrophic decline in river flows, residents
of Southern California have seen rate increases of up to 17
percent over the past two years.
Scientists said this week that a developing El Niño is likely
to amplify heatwaves, droughts and floods this
year, but warned that the long-term warming caused by
burning fossil fuels remains the main driver of climate
extremes. El Niño is the warm phase of a semi-regular
temperature oscillation in the tropical Pacific Ocean, during
which massive amounts of heat stored in the ocean are released
into the atmosphere, temporarily raising the average annual
global surface temperature by as much as 0.3 degrees
Fahrenheit. … Hotspots at the confluence of El
Niño-driven droughts and ongoing planetary heating are expected
in wildfire-prone regions, including … the
western United States. … [T]he combination of El
Niño on top of ongoing warming has driven a “whiplash” between
extreme moisture and extreme drought in some regions.
Yuba Water Agency has awarded an engineering contract worth up
to $8 million as it begins planning to rebuild the penstock
pipe that ruptured above New Colgate Powerhouse in February.
The agency selected GFT Inc. to conduct engineering and design
services related to the damaged penstock. A penstock is a
large, pressurized pipe that carries water from a reservoir
into a hydropower plant and then back into the river. The
penstock rupture occurred Feb. 13, when a 15-foot-diameter
section of pipe failed above New Colgate Powerhouse, releasing
an estimated 400 acre-feet of water down the hillside.
… It also led to the deaths of hundreds, possibly
thousands, of juvenile salmon after lower Yuba’s river flows
dropped by more than half.
Friant Water Authority is planning an “aggressive” outreach
campaign before Memorial Day weekend in an effort to keep
golden mussels out of several eastside reservoirs, including
Millerton Lake. The campaign includes social media and
handouts urging boaters “Clean, Drain and Dry” all
watercraft and trailers. This is especially important
for boaters who have visited the Sacramento-San Joaquin Delta,
ground zero for the golden mussel
infestation. Friant is working with California
State Parks and the Bureau of Reclamation to remind boaters to
check and clean watercraft before launching into Millerton
Lake. … Friant is also working on similar messaging with
the U.S. Army Corps of Engineers, which manages dam
infrastructure at Pine Flat, Kaweah Lake, Lake Success, Lake
Isabella.
After three consecutive years of closures and restrictions,
Chinook salmon fishing is set to return to major Northern
California river systems this summer and fall. … The
California Fish and Game Commission approved new sportfishing
regulations at its May 6 meeting, reopening salmon fishing on
the Klamath, Trinity and Sacramento river systems following
improved returns of adult Chinook salmon from the ocean.
… [L]ate spring-run Chinook salmon fishing in the
Klamath Basin will open July 1 and continue through Aug. 14 on
the Klamath River and through Aug. 31 on the Trinity River.
Fall-run Chinook fishing will begin Aug. 15 on the Klamath
River and Sept. 1 on the Trinity River, continuing through Dec.
31.
On Monday, May 11, Congressman Dr. Raul Ruiz (CA-25) convened a
federal roundtable at the Hector Mario Esquer Building in
Calexico bringing together EPA Region 9 leadership, federal and
state agency representatives, and Imperial County stakeholders
to advance solutions to the New River crisis. …
Congressman Ruiz pressed federal and binational partners to
expedite action ahead of the release of the International
Boundary and Water Commission-led binational water quality
study, expected in June 2026. … The New River originates
south of Mexicali, Mexico, carrying raw sewage, industrial
waste, pesticides, and heavy metals across the international
border into Calexico before traveling 60 miles through Imperial
County and emptying into the Salton Sea.
