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.
The Kern County Water Agency filed a motion May 30 seeking to
remove Kern County Superior Court Judge Gregory Pulskamp from
the long-running Kern River lawsuit saying it believes he is
prejudiced against the agency. It’s highly unusual – one
opposing attorney said improper – to try and get a judge
removed from a case without a ruling, much less one that hasn’t
even gone to trial yet. Disqualification efforts are typically
filed if one side gets a negative ruling at trial that’s later
overturned at a higher level and then sent back down to the
original judge. … The Kern County Water Agency is
making its case to Kern County’s Presiding Judge John Lua that
Pulskamp is biased against it because his preliminary
injunction, which had required enough water in the
river to support fish, was overturned by the 5th
District Court of Appeal. “The term ‘new trial’ is
interpreted broadly to include any reexamination of actual or
legal issues in controversy in the prior proceeding,” the
agency’s motion states.
Four bills authored by State Sen. Melissa Hurtado
(D-Bakersfield) have cleared the California Senate, advancing
to the State Assembly as part of what she calls her “Common
Sense Plan” to address affordability, infrastructure, and
corporate accountability in the Central Valley. … The
advancing legislation includes Senate Bill 224, the Preventing
Artificial Water Shortages Act, which would require the
Department of Water Resources to adopt better
forecasting tools to avoid unnecessary water releases.
Hurtado said the bill is aimed at avoiding the kind of
mismanagement that led to skyrocketing water prices in some
communities. … Senate Bill 556, the Flood Protection and
Groundwater Recharge Act, would direct funding toward
floodplain restoration projects in flood-prone
areas such as McFarland. The measure is intended to reduce
flood risks while helping to replenish groundwater supplies in
Kern, Kings and Tulare counties.
Other California water and environmental legislation news:
The Bureau of Reclamation announced an investment of $1.1
million to the Colorado River Indian Tribes to assess the
Colorado River Indian Irrigation Project. The funding will
assist the tribe to review existing infrastructure and identify
necessary maintenance. It will also be used to identify
potential opportunities to install new equipment and utilize
updated technology to modernize the project. “We appreciate the
Colorado River Indian Tribe’s collaboration for many years on
implementing its decreed water rights and the Water Resiliency
Act,” said Acting Commissioner David Palumbo. “We look forward
to utilizing this funding to further this partnership.” This
assessment is intended to assist the Colorado River Indian
Tribes as they evaluate a potential title transfer of the
project in order to take direct ownership. This could allow for
water leasing and other opportunities that could
contribute to overall water savings in the Colorado River
Basin.
The Yurok Tribe, California’s largest federally recognized
tribal nation, was given 73 square miles of land — or
47,097 acres — along the eastern side of the lower Klamath
River on Thursday. The land exchange is being called the
largest single “land back” deal in California history. … The
73 square miles of land is now owned and managed by
the Yurok Tribe as the Blue Creek Salmon Sanctuary and
Yurok Tribal Community Forest. … These lands — comprising
forests, river corridors, and prairies — support essential
habitat for many imperiled species, including coho and Chinook
salmon, marbled murrelets, northern spotted owls, and Humboldt
martens. In the face of climate change, Blue Creek remains a
crucial cold-water refuge for salmon, steelhead, and other
native fish.
Every year, boating enthusiasts across the Southwest hitch
watercraft to their vehicles and haul them down to Lake Mead,
a Colorado River reservoir straddling Arizona and
Nevada. This year, though, they’ll have to contend with
dramatically low water levels. According to the U.S. Bureau of
Reclamation, the reservoir’s 2025 elevation is the third lowest
it’s seen in a decade, and the Colorado’s
meager snowpack isn’t expected to help
matters. In response, the National Park Service is taking
steps to ensure that visitors can still recreate on the lake
this summer and beyond. But the future remains uncertain for
the country’s largest reservoir. … With reduced
supply, Lake Mead’s elevation is dwindling. At the end of May,
the reservoir sat at just 1,057 feet above sea level, according
to the Bureau of Reclamation. That’s 5 feet lower than the end
of April, which was another 4 feet lower than in March.
The small city of Lemoore recently joined the legal fight
against the powerful state Water Resources Control Board over
groundwater sanctions issued against Kings
County farmers by the state last year. The Lemoore City Council
on May 22 submitted an “amicus brief,” or friend of the court
motion, in support of an injunction that has, so far, held
those groundwater sanctions at bay. The injunction was
ordered by a Kings County Superior Court judge as part of a
lawsuit filed against the Water Board by the Kings County Farm
Bureau. The state appealed the injunction, which is now under
review by the 5th District Court of Appeal. … Because of
that injunction, local farmers have avoided having to meter and
register their wells at $300 each, report extractions and pay
$20 per acre foot pumped to the state. The sanctions were
issued after the Water Board placed the region on probationary
status in April 2024 for not having an adequate groundwater
plan.
The latest U.S. Drought Monitor shows growing dryness in
California. Parts of the northwest corner of the state are now
in the abnormally dry category. The typical impacts in this
category include growing fire risk, dry soils, and more
required irrigation. Other areas in the state remained
unchanged as of June 3, 2025. Much of Central and Southern
California are in some drought category. The Central and
Southern San Joaquin Valley from Merced County to parts of Kern
County is in moderate drought. Surrounding hill areas remain
abnormally dry. Farther south, from Santa Barbara to San
Diego Counties, coastal and inland communities remain in severe
drought. Dryness intensifies in parts of Inyo County, San
Bernardino County, Riverside County, San Diego and Imperial
County where extreme drought conditions are present. The most
intense category is exceptional drought which only covers a
small portion of the southeast corner of Imperial County.
After months of deliberation, the New Mexico Water Quality
Control Commission on May 14 voted to prohibit any discharge of
treated “produced water” from oil and gas extraction to ground
and surface waters. Produced water flows back to the
surface during fracking and conventional oil and gas drilling
and contains chemicals used in the extraction process as well
as numerous other hazardous compounds, including arsenic and
benzene, both human carcinogens. New Mexico creates around
two billion barrels—84 billion gallons—of this toxic wastewater
each year. Cleaning through multi-stage filtration,
desalination and other processes could allow for the reuse of
produced water for irrigation and other commercial
applications, saving precious water resources. But
environmental advocates, scientists and the New Mexico
Environmental Department (NMED) have urged that proper
regulations are not yet in place to make such reuse safe.
… The Groundwater Replenishment System facility in Orange
County, California, houses the pipes, filters and pumps to move
up to 130m gallons each day – enough for 1 million people –
processing it from dark to clear. The facility, which opened in
2008, is part of broader moves to help conserve water.
… The idea is to take the water from the sanitation
district next door and to push it through a three-step process
– microfiltration, reverse osmosis and ultraviolet light
purification – to make clean water. The facility provides 45%
of central Orange County’s water and helps manage storm water
inflows and reduce reliance on imported water. … In
general, once sewage has been treated, the water is returned to
our rivers, but extreme droughts and climate breakdown are
pushing cities to consider using recycled sewage for drinking
water. It is already done in Israel, Singapore and Kuwait, but
Orange County has been a US pioneer in this area, hoping to
reduce dependence on water piped from faraway rivers or pumped
from shrinking aquifers under the ground.
A collapsing coastal bluff is imperiling a key part of San
Clemente’s sewer system, the Linda Lane pump station, like
never before. Ten years ago, the city put up a retainer wall to
guard the pump station. An active, ever-encroaching landslide
has since forced San Clemente to scale the wall up to 8 feet in
height and reinforce it with raker system supports. Despite all
efforts, the slow-moving landslide has breached the wall around
the pump station and the city now faces the threat of a sewer
spill. The San Clemente City Council on Tuesday weighed
whether to approve a $2.3-million emergency contract to armor
the pump station with caissons and tiebacks before the arrival
of significant rainstorms or gamble by delaying the project for
a few months to solicit competitive bids. … According to
a city staff report, the pump station and beach trunk sewer
line transport about a million gallons of raw
wastewater every day to San Clemente’s water
reclamation plant to be treated.
A power outage caused by a vehicle collision, combined with a
backup system failure, has resulted in a massive fish die-off
at the Fish Springs Trout Hatchery near Big Pine. Both the
California Department of Fish and Wildlife (CDFW) and the Los
Angeles Department of Water and Power (LADWP) have confirmed
details of the May 20 incident, which could impact
recreational fish stocking across the Eastern Sierra
for the next two seasons. The hatchery—operated by CDFW—lost
electricity after a vehicle struck a power pole in the Owens
Valley. … While Fish Springs is equipped with diesel
backup motors designed to continue pumping water during
outages, a software malfunction rendered the motors inoperable
at the time. … CDFW estimates that between 75 to 80
percent of the hatchery’s fish stock—ranging from eggs and
fingerlings to catchable-size trout—was lost during the outage.
The hatchery raises rainbow trout, brown trout, and Lahontan
cutthroat trout, which are vital to recreational fishing in
Inyo and Mono County waters.
… 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.
