A new cannabis industry-led program has launched to control
sediment and restore watersheds across Northern California, the
nonprofit Cannabis for Conservation said Thursday. The
Arcata-based organization is dedicated to conserving wildlife
and restoring habitats in cannabis-impacted areas. It recently
received a grant from the California Department of Fish and
Wildlife to implement the Sediment Reduction on Cannabis Farms
in Priority Northern Watersheds program starting this
month. According to CFC, over the next three years the
program will support projects on over 40 privately-owned
properties in watersheds that feed into the Eel, Mad, Trinity
and Mattole rivers. The goal of the program is to reduce
harmful sediment production and restore degraded watersheds,
CFC said. All the areas to be served through the project have
been impacted by cannabis cultivation and rural development.
… The CFC grant was awarded through the CDFW’s Cannabis
Restoration Grant Program, which is funded through cannabis tax
revenue.
The U.S. Army Corps of Engineers Los Angeles District joined
the City of Inglewood June 13 to officially sign a project
agreement that will strengthen the city’s emergency water
storage capacity and spotlight more than two decades of
interagency collaboration. The agreement, supported by federal
funding through Section 219 of the Water Resources Development
Act, will assist in the design and construction of the
Morningside Reservoir — the first and
highest-priority of four planned water infrastructure projects.
The overall program is expected to support up to $20 million in
improvements across Inglewood’s aging water system.
… The new reservoir, which will be constructed below
grade on the existing site, is designed to hold about 4 million
gallons of water. It will mix groundwater from Inglewood’s
treatment plant with supply from the Metropolitan Water
District and distribute it citywide.
President Donald Trump has tapped longtime water manager Ted
Cooke to be the next commissioner of the U.S. Bureau of
Reclamation. The nomination, submitted Monday to the
Senate Committee on Energy and Natural Resources, attempts to
fill a pivotal role at the top federal agency for Western
rivers, reservoirs and dams. If confirmed, Cooke will become
the main federal official overseeing Colorado River matters.
His nomination comes at a tense time for the river. The seven
states that use its water appear deadlocked in closed-door
negotiations about sharing the shrinking water supply in
the future. Cooke will likely try to push those state
negotiators toward agreement about who should feel the pain of
water cutbacks and when. If they can’t reach a deal ahead of a
2026 deadline, the federal government can step in and make
those decisions itself.
Other Reclamation and Colorado River negotiation news:
Tulare County farmers are incensed by a proposed new fee
structure that they say will put the entire burden of state
groundwater oversight across the San Joaquin Valley solely on
their shoulders. It costs the state Water Resources Control
Board about $5.5 million a year to oversee six basins in the
San Joaquin Valley that have been found to have inadequate
groundwater plans as part of the Sustainable
Groundwater Management Act (SGMA). Two of those
subbasins have been placed on probation, under which farmers
are required to pay fees to reimburse the state for those
oversight costs. One of those subbasins has, so far,
escaped the fees pending the outcome of a legal
action. … At a June 11 online Water Board workshop,
staff unveiled a new fee structure they say will repay state
costs and protect small farmers. Tule subbasin farmers say the
proposed fee structure, expected to raise $6.6
million, is unfair.
Aspen residents could face mandatory water restrictions this
month as the city responds to a drought parching western
Colorado. Water experts warn that the low snowpack could lead
to more severe drought as the summer progresses. Aspen is
already under Stage 1 Water Shortage, after the city council
voted to institute the measures last week. The goal is to
reduce water use by 10 percent by reducing use at public
facilities, and urging voluntary conservation by businesses and
residents in the 6,600-person resort community.
… Snowpack was low this winter, and high temps have
caused a faster melt. That’s resulted in lower stream runoff
forecasts, said Nagam Bell, a hydrologist at the USDA Natural
Resources Conservation Service, in a report. “Early monsoon
activity could improve moisture conditions, but consistent
summer rainfall will be critical moving forward,” they
said.
Other drought and water supply news around the West:
The first discovery of golden mussels in North
America at Rough and Ready Island near Stockton in San Joaquin
County has water managers throughout California on the alert,
including the Yuba Water Agency, which manages New Bullards Bar
Reservoir. On Tuesday, the Yuba Water Agency announced that it
will launch a new watercraft screening pilot program later this
summer at New Bullards Bar Reservoir in Yuba County. The pilot
program aims to prevent the spread of the golden mussel, a
highly invasive species found in the Sacramento-San
Joaquin Delta last fall that could pose a
significant ecological and economic threat to the Yuba River
watershed. … Thus far, all the sightings of golden
mussel have been concentrated in the delta, although five
additional sightings have been reported in the San Joaquin
Valley.
… For more than a century, hydroelectric dams have diverted
water through the valley from the northward flowing Eel River’s
watershed to the southerly Russian River’s east fork, where the
two wind within a mile of each other near the Lake County
border. The local ecology, economy and culture have adapted
accordingly. Now that the alteration is no longer
profitable, Pacific Gas & Electric is looking to undo the
diversion by removing the dams, with potentially devastating
ramifications for the communities that have grown to depend on
the water they store and divert. … A coalition of
considerable political force has aligned behind PG&E’s
effort to relinquish its license for the Potter Valley
Project. Environmental nonprofits, tribal
representatives and elected officials, including Rep. Jared
Huffman, have endorsed the removal of Scott Dam, citing seismic
risk, fish habitat restoration and historical justice for the
Round Valley Indian Tribes as core motivations.
Over 250 million acres of public lands could be eligible for
sale if the President’s budget reconciliation package,
something he has called the “big, beautiful bill,” is passed. A
map and analysis were created by The Wilderness Society using
source data from BLM, USFS, USGS, NPS, and SENR reconciliation
bill text (Senate Energy and Natural Resources) as of June
16, 2025. … The map includes Kiva Beach, much of Fallen Leaf
Lake, Tallac Historic Site, and even ski resorts who lease land
from USFS, including Alpine Meadows, Heavenly Valley, as well
as other treasured acreage through the Sierra and beyond.
… The mandates of the bill call for the sale of .5-.75
percent of each BLM and USFS land across 11 western states, or
about 3.3 million acres. It opens up 250 million acres for
“developers to pick from,” to get to the 3.3 million acres,
according to Oliva Tanager of the Sierra Club.
New data from Nasa has revealed a dramatic rise in the
intensity of weather events such as droughts and
floods over the past five years. The study shows that
such extreme events are becoming more frequent, longer-lasting
and more severe, with last year’s figures reaching twice that
of the 2003-2020 average. The steepness of the rise was not
foreseen. The researchers say they are amazed and alarmed by
the latest figures from the watchful eye of Nasa’s Grace
satellite, which tracks environmental changes in the planet.
They say climate change is the most likely cause of the
apparent trend, even though the intensity of extremes appears
to have soared even faster than global temperatures. A Met
Office expert said increases in extremes have long been
predicted but are now being seen in reality. He warned that
people were unprepared for such weather events, which would be
outside previous experience.
President Donald Trump recently addressed Mexico’s failure to
pay the water it owes the U.S. under a decades-old treaty.
Under the 1944 treaty, Mexico must send 1.75 million acre-feet
of water to the U.S. from the Rio Grande every five years, and
the United States is to pay Mexico 1.5 million acre-feet of
water annually via the Colorado River out West. Mexico,
however, has fallen behind on its payments. … The water
payments are just one of several water-related issues at which
the U.S. and Mexico are at odds. In San Diego, raw sewage has
been flowing in from Mexico for decades via the Tijuana River,
which runs from the south to the north. When it rains, tons of
debris and trash, in addition to millions of gallons of
sewage-tainted water, make their way north of the border and,
eventually, into the Pacific Ocean. The bacteria in the water
has forced the closure of beaches in southern San Diego that
have already been in place for years.
The Pima County Board of Supervisors voted 3-2 Tuesday to allow
a developer to purchase public land for a planned $3.6 billion
data center just southeast of Tucson, and approved a rezoning
of the parcel to allow for the construction project. After
being rezoned with a 3-2 vote, the board voted to sell the the
290-acre parcel, which will be acquired by the San
Francisco-based developers for nearly $20.8 million. The
controversial agenda items passed after dozens spoke in front
of the board about what they saw as problems with the planned
project, including the large amounts of water and electricity
the data center will require. … The developer, San
Francisco-based Beale Infrastructure, promises to remain 100
percent sustainable through reclaimed water
delivered by a pipeline built at the developer’s expense. They
also agree to replenish all potable water used. Despite these
promises, much of the public continued to voice their
frustration with the potential long-term negative impacts.
… Over the course of his (Alameda Creek Alliance founder Jeff
Miller’s) career, he has participated in lawsuits, protests,
and hundreds of board meetings, alongside hundreds of other
people. More than $100 million dollars have been spent across
state funding, federal grants, and agency money. Almost every
barrier to fish migration in Alameda Creek has been removed.
This week, the last barrier that can feasibly be removed in our
lifetimes—a concrete structure over a PG&E gas
pipeline—will begin coming down. By 2026, Alameda Creek will
flow free. This final barrier removal opens up some twenty
miles of creek—a new survival path for steelhead in the Bay.
But what is just as remarkable is the three-decade process that
got us to this point has reshaped not only the creek but our
public agencies, and their approach to fish and watershed
stewardship.
A major lithium extraction project in Imperial County,
currently blocked in state court, just got a boost from the
Trump administration aimed at helping the project navigate
federal hurdles. Controlled Thermal Resources’ Hell’s Kitchen
project was designated under the federal FAST-41 program, an
Obama-era initiative that helps coordinate and keep
environmental reviews on schedule. The designation is the first
show of support since Trump took office in January for projects
in Lithium Valley, named for the vast stores of lithium
estimated to be buried beneath the Salton Sea.
… Controlled Thermal Resources broke ground on the
Hell’s Kitchen project on the south end of the Salton Sea last
year, racing to be the first to extract lithium on a commercial
level in the region. But environmental groups sued to block the
project, which remains on hold after the groups appealed the
dismissal of their lawsuit. No companies have launched
commercial extraction yet.
A special fund set up by the Arizona Legislature and former
Gov. Doug Ducey in 2022 to provide $1 billion to secure new
water supplies in the desert state is once again being raided
to help balance the state budget. The move to use more than $70
million in the Long Term Water Augmentation Fund was called
shortsighted by a representative of the state agency charged
with using the cash to bring new water to the state.
… All that started with 2022 legislation championed by
former Republican Gov. Doug Ducey to set aside $333 million a
year in three successive years so the authority would have $1
billion dedicated to finding and developing new water sources —
mainly from outside of the state. Ducey was intent on having
the state develop a water desalination plant on the Gulf of
Cortez in Mexico and piping the water to Arizona. That plan
fell apart, at least in part because of the secrecy surrounding
it and in part because the Mexican government said it never was
consulted. That has left the WIFA fund with money that
lawmakers decided could be used for something else.
The first visitors to enter the renovated Hoover Dam Visitor
Center on Tuesday morning made their way slowly through the
building’s new exhibit, exploring each facet of life that made
the dam’s construction possible. For the people behind the
project, that meant illustrating both the dangers people put
themselves through during the Great Depression and the
typically ignored spouses who made life in Boulder City
possible. Terri Saumier, a facility services manager under the
U.S. Bureau of Reclamation, said the $15 million project had a
focus on telling the dam’s “story through the people who lived
it” from Day 1. … U.S. Rep. Dina Titus, D-Nev., and
Boulder City Mayor Joe Hardy joined reclamation officials for
the visitor center’s ribbon-cutting ceremony, which also
coincided with the bureau’s 123rd anniversary.
A pipeline project designed to provide clean, accessible water
to residents living in eastern Coachella Valley has been
completed, Coachella Valley Water District officials announced
today. The Avenue 66 Transmission project, also
known as the Saint Anthony Mobile Home Park Water Consolidation
project, involved the installation of more than 26,000 linear
feet of water pipes along Avenue 66. The project connects to
three mobile home parks — Saint Anthony, Seferino Huerta and
Manuela Garcia — and will supply water to the communities of
Mecca and North Shore. ”Access to safe, affordable water
and sewer services brings additional benefits, including new
housing opportunities and economic growth,” CVWD Board Vice
President Castulo Estrada said in a statement. Numerous eastern
Coachella Valley residents previously received water from
failing or at-risk private water systems and unreliable
sanitation systems, district officials said.
President Donald Trump has quietly nominated a veteran Arizona
water official to lead the Bureau of Reclamation. Ted Cooke, who
spent more than two decades at the Central Arizona Project (CAP)
— the state’s largest water delivery agency, which distributes
Colorado River water to Maricopa, Pinal and Pima counties — would
become Reclamation’s next commissioner if confirmed by the
Senate. Trump submitted Cooke’s nomination to
Congress on Monday.
President Donald Trump promised to break California’s water
rules wide open. So far, he’s mostly working within them. Five
months after Trump issued a pair of directives for federal
agencies to overturn state and Biden-era rules limiting water
deliveries, the federal government has done no such thing.
Instead, it’s quietly increasing water flows following the very
rules Trump once railed against — at least for
now. … What’s changed? For one, California had a
wet winter, which tends to smooth over political differences.
… Newsom has also aligned himself more with Trump on water,
as when he jilted Delta-area Democrats last month in pushing to
expedite a tunnel to move more supplies from Northern to
Southern California. More substantively, some of the water
districts that might be expected to agitate for Trump to
overturn Biden-era water rules concede that they actually allow
more deliveries than Trump’s version.
Other Trump administration and California water news:
… The Colorado River system rushes through
turbines inside Glen Canyon Dam on Lake Powell, producing
affordable, carbon-free hydropower. … Climate change and
chronic water overuse continue to constrict the mighty river’s
flows, though, jeopardizing the dam’s ability to produce
hydroelectric power. The lack of water has also created a slew
of environmental problems in the Grand Canyon’s ecosystem,
which sprawls below Glen Canyon Dam — most notably for an
ancient, threatened fish species, the humpback chub, which is
hunted by invasive smallmouth bass. Under Biden last year, the
U.S. Bureau of Reclamation finalized a decision that allows the
dam to periodically release surges of water that bypass the
machinery that generates power. These flows cool the river
below the dam, which curbs smallmouth bass reproduction. Utah
Republicans and power providers say that decision has only
further threatened the valuable energy source — and they hope
to undo it.
After sitting near capacity for almost a month, Lake Oroville
is beginning to slowly creep back down in water elevation as
the California Department of Water Resources steadily increases
outflows. Lake Oroville was reported at 896.35 feet in
elevation Monday and will likely lower more in the weeks to
come. DWR spokesperson Raquel Borrayo said the lake was once
again bolstered by a wet and snowy winter. “Thanks to
above-average precipitation and average snowpack levels in the
northern Sierra for the last three years, water levels at Lake
Oroville have been peaking in May and June and then slowly
declining to their low point around November,” Borrayo said.
Borrayo said the higher releases are sent into the Feather
River, though some of the water remains local. … On
Monday, inflows into Lake Oroville were estimated at 3,000
cubic feet per second.
