The Mendocino County Board of Supervisors has approved a
nonbinding resolution in support of PG&E’s plan to
decommission the Potter Valley Project’s dams. The resolution
was approved 3-2. … [Supervisor Ted] Williams’
resolution, included on the Oct. 21 Board of Supervisors
agenda, got new additions and edits and was moved forward to
last week’s meeting as an alternative to a separate resolution
sponsored by Cline and Norvell. Williams’ resolution outlines
the positive impacts of the removal of the dams, such as fish
restoration and support for local Native American communities,
including the Round Valley Indian Tribes.
General manager Deven Upadhyay has guided Metropolitan Water
District through major droughts and much more. As he prepares
to retire at the end of the year, we sat down with him to talk
about his experiences guiding an urban water agency through the
volatile 21st century. … [Upadhay:] Metropolitan is the
largest treated drinking water provider in the US. Just a few
years ago, 85% of our revenue came from volumetric fees on the
amount of water we delivered each year and just 15% of our
revenue came from fixed charges—but our costs were the
opposite. We’ve been struggling with that. … We’re looking at
multiple tools to raise revenue, including levying fixed
charges and property taxes and conducting water sales outside
of our service area.
Iran’s president has warned that the capital is facing an
unprecedented water and energy crisis as reservoirs have
plunged to historic lows, threatening supplies of drinking
water and electricity generation. … The city has entered
its sixth consecutive year of drought, with some dams at less
than 10% of capacity. Officials say that in the east of Tehran,
the Latyan Dam — one of five key reservoirs — is only about 9%
full. … Experts say the link between water availability
and electricity generation has become increasingly evident, as
hydropower output drops and thermal plants struggle with
cooling shortages.
Chemical-laden dust from southern California’s drying Salton
Sea is probably harming the lungs of people around the
shrinking body of water, and the effects are especially
pronounced in children, new peer-reviewed research from the
University of California, Irvine, shows. A separate
peer-reviewed study from the University of California,
Riverside, also found the Salton Sea’s contaminated dust seemed
to alter lung microbiome, which could trigger pulmonary
problems that have been reported around the lake. The two
new papers are part of a series of studies that are revealing
the environmental and public health risks of dust from the
drying Salton Sea.
Stockton’s downtown waterfront faces an annual takeover by
invasive water hyacinth, a fast-growing plant that can blanket
thousands of square feet of water in a single season. Deemed
“hopeless” by PBS in 2015, the plant returns each year to San
Joaquin County waterways, including McLeod Lake in Stockton,the
Calaveras River and the broader Sacramento-San Joaquin Delta.
Known as “the fastest-growing plant in the world,” a single
hyacinth can wreak massive ecological and economic damage,
making it one of California’s most destructive invasive
species. Unlike other invasive plants, experts say eradication
is nearly impossible, leaving ongoing control as the only
viable solution.
The County of San Diego has selected Olivewood Gardens and
Learning Center as the new operator of the Tijuana River Valley
Community Garden, ensuring continuity for hundreds of plot
owners at the region’s largest community garden. Olivewood
Gardens, a nonprofit founded in National City, will serve as
interim operator for up to one year following the Resource
Conservation District of Greater San Diego County’s decision to
terminate its lease in September due to health and safety
concerns related to the Tijuana River sewage crisis.
Water and sewer rate increases proposed in October to take
effect in 2026 for Oceanside residents and businesses were cut
in half Wednesday by the Oceanside City Council, but only for a
year. Water department employees initially asked for increases
of 6% for water and 4% for sewer in 2026 and again in 2027, but
the council pushed for belt-tightening and postponed a decision
after complaints from residents at the Oct. 1 meeting. The
revised proposal, approved 3-2 Wednesday with Mayor Esther
Sanchez and Councilmember Rick Robinson opposed, calls for a 3%
hike for water and 2% for sewer in 2026 and then the 6% and 4%
increases in 2027.
A federal project cutting trees on the American River Parkway
to fortify banks against flooding could be stalled as a judge
heard arguments Friday from environmental groups seeking a
preliminary injunction. The U.S. Army Corps of Engineers
planned flood protection measures at the lower American River,
Natomas East Main Drainage Canal, Arcade Creek and Magpie
Creek. … The American River Parkway is at the heart of a
lawsuit filed by Sacramento nonprofits and the Center for
Biological Diversity, a national environmental conservation
group. A judge will consider whether to block a 3.3-mile
portion of the Corps’ work, between Watt and Howe avenues.
Pacific Gas and Electric has announced it will stop diverting
water through the Miocene Canal. This change is taking effect
after the Butte County Board of Supervisors recently approved
an amendment to a 2014 water supply agreement between Butte
County, the Butte County District Attorney’s Office, and
PG&E. Currently, PG&E diverts water from the West
Branch Feather River at the Miocene Head Dam, runs it through
about 500 yards of the canal for measurement purposes, and then
returns the water back to the river. The water eventually flows
into Lake Oroville and is used in the State Water
Project.
Aquafornia is taking off Monday, Nov. 10, to
observe Veterans Day, but will return with a full slate of
water news on Tuesday, Nov. 11, on the official holiday.
California legislators considered dozens of bills related to
artificial intelligence this year. That’s a number that’s
climbed quickly over the last couple years as lawmakers grapple
with the technology’s increasing presence — and possible
negative impacts. And one growing point of concern
involves generative AI’s relationship with state resources as
the technology becomes everyday life for Californians. Experts
say generative AI is driving up energy and water
demands at data centers. But the question is: By
how much?
Progress appears to be happening in the high-stakes
negotiations over the future of the Colorado River. Ahead of a
Tuesday deadline by the Trump administration for a deal in
principle, the Colorado River Commissioner for Utah said in a
statement to FOX 13 News that they may get there. … “We’re
making steady progress on key issues the federal government has
identified, aiming to reach broad alignment by November 11—even
if the finer details come later,” said Gene Shawcroft.
… Despite the uncertainty, there is growing confidence that a
storm will impact much of California by
Thursday, potentially the rainiest of any storm so far
this season. … One potential outcome of the complex
weather pattern is a prolonged period of wet weather, not only
in Northern California, but across the entire state. … The
[National] weather service highlights two areas of California
for the greatest chances of heavy precipitation: the Sierra
Nevada and the Southern California coastline. It’s too early to
speculate whether precipitation will fall as rain or snow in
Tahoe, but the agency also predicts heavy snow in the
highest elevations of the Sierra.
Other weather and water supply news across the West:
A state legislative committee failed to pass a bill draft last
week that would have placed a 10-year moratorium on all cloud
seeding activities in the state. During the moratorium, the
Wyoming Department of Environmental Quality would have been
tasked with completing a study of cloud seeding impacts
compared to baseline conditions, according to the initial bill
proposal – but University of Wyoming Atmospheric Science
Department Head Jeff French said that plan wouldn’t be
“scientifically sound.” … “The only way I could see us
actually being able to measure the effectiveness of cloud
seeding is by doing a focused study that includes cloud
seeding.”
The Trump administration will soon propose changes to a Clean
Water Act regulation that allows states and tribes to veto
major energy projects over water pollution concerns. EPA’s
pending “Clean Water Act Section 401 Water Quality
Certification Improvement Rule” was sent Wednesday to the White
House Office of Management and Budget for interagency review,
according to a notice from the office. Section 401 of the
law requires companies seeking a permit from the Army Corps of
Engineers, the Federal Energy Regulatory Commission or other
agencies to also obtain a water quality certification from
states or tribes in which their project is located.
Two Kings County water agencies are holding public workshops
Nov. 12 and 14 to explain their pumping allocations. The
Mid-Kings River and South Fork Kings groundwater sustainability
agencies (GSAs) both passed draft sustainable yield pumping
allocations for their farmers in October. … But South Fork
farmers objected to Mid-Kings’ allocation of 1.43 acre feet per
acre of land, which is more than double what was set in South
Fork at .66 acre foot per acre of land.
It could cost $27 million, or more, to revamp and reopen
the Kernville hatchery as a Kern River rainbow trout
breeding facility, according to a report commissioned by the
California Department of Fish and Wildlife. Costs would be less
to rehab the hatchery as just a fish planting base but neither
the report nor CDFW had estimates for that lesser function. In
either case, those amounts are separate from what CDFW is
already spending to rebuild about a mile-long siphon to bring
Kern River water into the hatchery. The siphon project is
expected to cost $7 million and be completed in 2027.
U.S. Sens. Ted Cruz and John Cornyn want to limit the U.S.’s
engagement with Mexico after the country failed to deliver
water to Texas under a 1944 international water treaty. The
Texas senators filed legislation Thursday that would limit the
U.S. from sending Mexico future deliveries of water and would
allow the U.S. president to stop engaging with Mexico in
certain business sectors that benefit from U.S. water. The
treaty requires the U.S. to deliver 1,500,000 acre-feet of
water from the Colorado River to Mexico every
year.
The Board of Supervisors discussed a resolution requesting
equitable Proposition 4 funding distribution for the New River
during the regular board meeting Tuesday, Nov. 4. Deputy CEO of
General Services for the County of Imperial, Gil Rebollar …
said that within the water chapter of Proposition 4, a
$10-billion climate bond that voters approved in Nov. 2024,
“there’s a specific line for California-Mexico rivers and
coastal waters.” … Rebollar said the resolution places
Imperial County on record as saying that the New River and
Salton Sea projects are eligible for a funding allocation and
emphasizes that Imperial County is seeking an equitable share
of the funding.
State officials grilled Water Development Office Director Jason
Mead this week over ballooning costs and uncertainties dogging
three dam projects after he told them one project on the
Colorado border would cost $150 million, nearly double the
original estimate of $80 million. … The proposed
reservoir would release stored water into the Little Snake
River, which flows back and forth across the Colorado border
before leaving Wyoming for good, flowing into the Yampa, Green
and Colorado rivers. The dam and reservoir would allow Wyoming
to use more water from the Colorado River Basin.
