… The City’s aging combined sewer infrastructure – and the
increasing cost to maintain it – forced San Francisco into an
odd position on the wrong side of clean water advocacy. This
recently culminated in March 2025. In a 5-4 decision, the
Supreme Court ruled in favor of San Francisco in its case
against the EPA, significantly limiting the federal
government’s ability to enforce water quality standards
nationwide. The case began when San Francisco challenged
EPA regulations to avoid penalties for discharging sewage into
the Bay and Pacific Ocean from its combined sewer system. The
city argued that the Clean Water Act doesn’t authorize the EPA
to include broad “end-result” requirements in
permits—essentially fighting for less oversight of its
pollution. … While the Supreme Court decision represents
a significant setback for clean water protections nationwide,
it also creates an opportunity for grassroots action. Cities
across America, including San Francisco, can voluntarily
implement so-called “Green Infrastructure” solutions that
reduce pollution without waiting for federal mandates.
… The Inland Water & Power Commission had an all-boards’
meeting on May 29. Since the IWPC is composed of different
boards, this was an opportunity for all the boards to hear the
same update. My takeaways are: PG&E is going to take down
the dams. A coalition has formed to build a New Eel
Russian Facility (NERF) that will divert water during
high water times from the Eel River to the Russian River. The
current projection is that the NERF will cost $40 million to
build and $10 million annually to operate. The process will
take years, and people/groups in both basins have agreed to
this plan. Storage of water on the Russian River side is
critical to making it all work, and a feasibility study by the
United States Army Corps of Engineers is beginning to study the
raising of Coyote Dam. That will be a very expensive and long
process. There has been a lot of work done by very dedicated
people, coalitions have been formed from entities from both
basins, and continuing to work through the issues is the only
realistic path forward to keep water flowing in both
directions. –Written by John Haschak, chair of the Mendocino County
Board of Supervisors.
Visitors have five new trails at Dos Rios Ranch State Park,
nearly a year after it opened southwest of Modesto. The public
can enjoy them starting at 7 a.m. Friday, June 6. They go
farther out on the Tuolumne and San Joaquin
rivers than the initial two trails. They also provide
easy access for the first time to swimming and fishing spots.
… Dos Rios was created on about 1,600 acres of one-time
floodplain where the two rivers join. Restoration began in
2012, led by River Partners and aided by the Tuolumne River
Trust. The nonprofits had more than $40 million from numerous
public agencies. Former farm fields gave way to native
trees, brush and grasses. Fast-growing cottonwoods, willows and
other plantings shelter and feed wildlife. The place was
designed to absorb high river flows, protecting Grayson and
other towns downstream.
You may have heard of the term subsidence but what does it
mean? Subsidence is the sinking of land which can be caused by
various factors including groundwater pumping. In California,
subsidence has been documented for over a century and is a
growing issue that impacts our water infrastructure and the
communities who rely on it. This summer, DWR plans to release a
draft best management practices document to help local agencies
minimize subsidence impacts around the state. For more
information about DWR’s efforts to sustainable manage
groundwater and reduce the impacts of subsidence visit DWR’s
Groundwater Management page.
A serendipitous observation in a chemical engineering lab at
Penn’s School of Engineering and Applied Science has led to a
surprising discovery: a new class of nanostructured materials
that can pull water from the air, collect it in pores and
release it onto surfaces without the need for any external
energy. The research, published in Science Advances, is
conducted by an interdisciplinary team including Daeyeon Lee,
Russell Pearce and Elizabeth Crimian Heuer Professor in
Chemical and Biomolecular Engineering (CBE), Amish Patel,
professor in CBE, Baekmin Kim, a postdoctoral scholar in Lee’s
lab and first author, and others. Their work describes a
material that could open the door to new ways to collect water
from the air in arid regions and devices that cool electronics
or buildings using the power of evaporation.
Seeking to prevent the California State Water Resources Control
Board from stepping in to regulate groundwater in critically
overdrafted subbasins, local agencies are working to correct
deficiencies in their plans to protect groundwater. With
groundwater sustainability agencies formed and groundwater
sustainability plans evaluated, the state water board has moved
to implement the 2014 Sustainable Groundwater Management Act,
or SGMA. … Under probation, groundwater extractors in
the Tulare Lake subbasin face annual fees of $300 per well and
$20 per acre-foot pumped, plus a late reporting fee of 25%.
SGMA also requires well owners to file annual groundwater
extraction reports.
Last year’s snow deluge in California, which quickly erased a
two decade long megadrought, was essentially a
once-in-a-lifetime rescue from above, a new study found. Don’t
get used to it because with climate change the 2023 California
snow bonanza —a record for snow on the ground on April 1 — will
be less likely in the future, said the study in Monday’s
journal Proceedings of the National Academy of Sciences.
… UCLA climate scientist Daniel Swain, who wasn’t part
of the study but specializes in weather in the U.S. West, said,
“I would not be surprised if 2023 was the coldest, snowiest
winter for the rest of my own lifetime in California.”
Six tribes in the Upper Colorado River Basin, including two in
Colorado, have gained long-awaited access to discussions about
the basin’s water issues — talks that were formerly
limited to states and the federal government. Under an
agreement finalized this month, the tribes will meet every two
months to discuss Colorado River issues with an interstate
water policy commission, the Upper Colorado River Commission,
or UCRC. It’s the first time in the commission’s 76-year
history that tribes have been formally included, and the timing
is key as negotiations about the river’s future intensify.
… Most immediately, the commission wants a key number:
How much water goes unused by tribes and flows down to the
Lower Basin?
A group of Western lawmakers pressed the Biden administration
Monday to ramp up water conservation, especially in national
forests that provide nearly half the region’s surface water.
“Reliable and sustainable water availability is absolutely
critical to any agricultural commodity production in the
American West,” wrote the lawmakers, including Sens.
Michael Bennet (D-Colo.) and Martin Heinrich (D-N.M.), in a
letter to Agriculture Secretary Tom Vilsack. The 31
members of the Senate and House, all Democrats except for Sen.
Kyrsten Sinema (I-Ariz.), credited the administration for
several efforts related to water conservation, including
promoting irrigation efficiency as a climate-smart practice
eligible for certain USDA funding through the Inflation
Reduction Act.
A study led by NASA researchers provides new estimates of how
much water courses through Earth’s rivers, the rates at which
it’s flowing into the ocean, and how much both of those figures
have fluctuated over time—crucial information for understanding
the planet’s water cycle and managing its freshwater supplies.
The results also highlight regions depleted by heavy water use,
including the Colorado River basin in the United States, the
Amazon basin in South America, and the Orange River basin in
southern Africa.
State water management officials must work more closely with
local agencies to properly prepare California for the effects
of climate change, water scientists say. Golden State
officials said in the newly revised California Water
Plan that as the nation’s most populous state, California
is too diverse and complex for a singular approach to manage a
vast water network. On Monday, they recommended expanding the
work to better manage the state’s precious water resources —
including building better partnerships with communities most at
risk during extreme drought and floods and improving critical
infrastructure for water storage, treatment and distribution
among different regions and watersheds.
It’s the most frustrating part of conservation. To save water,
you rip out your lawn, shorten your shower time, collect
rainwater for the flowers and stop washing the car. Your water
use plummets. And for all that trouble, your water supplier
raises your rates. Why? Because everyone is using so much less
that the agency is losing money. That’s the dynamic in
play with Southern California’s massive wholesaler, the
Metropolitan Water District, despite full reservoirs after two
of history’s wettest winters. … Should water users be
happy about these increases? The answer is a counterintuitive
“yes.” Costs would be higher and water scarcer in the future
without modest hikes now.
A steady stream of water spilled from Lake Casitas Friday, a
few days after officials declared the Ojai Valley reservoir had
reached capacity for the first time in a quarter century. Just
two years earlier, the drought-stressed reservoir, which
provides drinking water for the Ojai
Valley and parts of Ventura, had dropped under 30%.
The Casitas Municipal Water District was looking at emergency
measures if conditions didn’t improve, board President Richard
Hajas said. Now, the lake is full, holding roughly 20 years of
water.
After nearly a century of people building dams on most of the
world’s major rivers, artificial reservoirs now represent an
immense freshwater footprint across the landscape. Yet, these
reservoirs are understudied and overlooked for their fisheries
production and management potential, indicates a study from the
University of California, Davis. The study, published
in the journal Scientific Reports, estimates that U.S.
reservoirs hold 3.5 billion kilograms (7.7 billion pounds) of
fish. Properly managed, these existing reservoir ecosystems
could play major roles in food security and fisheries
conservation.
California has unveiled an ambitious plan to help combat the
worsening climate crisis with one of its invaluable assets: its
land. Over the next 20 years, the state will work to transform
more than half of its 100 million acres into multi-benefit
landscapes that can absorb more carbon than they release,
officials announced Monday. … The plan also calls for
11.9 million acres of forestland to be managed for biodiversity
protection, carbon storage and water supply protection by 2045,
and 2.7 million acres of shrublands and chaparral to be managed
for carbon storage, resilience and habitat connectivity, among
other efforts.
The California Department of Fish and Wildlife recommended
Alternative 3 – Salmon Closure during the final days of the
Pacific Fisheries Management Council (PFMC) meeting mirroring
the opinions of commercial and recreational charter boat
anglers. The department’s position is a significant change from
early March. The PFMC meetings are being held in Seattle from
April 6 to 11, and the final recommendations of the council
will be forwarded to the California Fish and Game Commission in
May.
Sustaining the American Southwest is the Colorado River. But
demand, damming, diversion, and drought are draining this vital
water resource at alarming rates. The future of water in the
region – particularly from the Colorado River – was top of mind
at the 10th Annual Eccles Family Rural West Conference, an
event organized by the Bill Lane Center for the American West
that brings together policymakers, practitioners, and scholars
to discuss solutions to urgent problems facing rural Western
regions.
Today, Congresswoman Norma Torres and Congressman David Valadao
– members of the House Appropriations Committee – announced the
introduction of the bipartisan Removing Nitrate and Arsenic in
Drinking Water Act. This bill would amend the Safe Drinking
Water Act to provide grants for nitrate and arsenic reduction,
by providing $15 million for FY25 and every fiscal year
thereafter. The bill also directs the Environmental
Protection Agency (EPA) to take into consideration the needs of
economically disadvantaged populations impacted by drinking
water contamination. The California State Water Resources
Control Board found the Inland Empire to have the highest
levels of contamination of nitrate throughout the state
including 82 sources in San Bernardino, 67 sources in Riverside
County, and 123 sources in Los Angeles County.
Catastrophic weather events wreaked havoc on U.S. agriculture
last year, causing nearly $22 billion in crop and rangeland
losses, according to the American Farm Bureau Federation.
California accounted for $1.14 billion of that figure,
including nearly $880 million in damages from severe storms and
flooding. The figures represent a significant shift from
previous years, when drought and wildfires were California’s
biggest challenges. Since then, atmospheric rivers, Tropical
Storm Hilary and other weather events battered our farming
communities. - Written by Matthew Viohl, director of federal
policy for the California Farm Bureau
Water bubbles up in streets, pooling in neighborhoods for weeks
or months. Homes burn to the ground if firefighters can’t draw
enough water from hydrants. Utility crews struggle to fix
broken pipes while water flows through shut-off valves that
don’t work. … Across the U.S., trillions of gallons of
drinking water are lost every year, especially from decrepit
systems in communities struggling with significant population
loss and industrial decline that leave behind poorer residents,
vacant neighborhoods and too-large water systems that are
difficult to maintain.
