Mexico’s national university and a U.S. NGO comprising water
management experts have agreed to jointly develop a digital
platform with information on the water resources that the two
neighboring countries share. The National Autonomous University
of Mexico (UNAM)’s Institute of Geography will work with the
Permanent Forum on Binational Waters (PFBW) to create and run
the platform that will include scientific data, maps and other
key information in Spanish and English about the shared water
sources in the border region, most prominently the Río Bravo
(Rio Grande on the U.S. side), the Colorado
River and the Tijuana River basin.
After Colorado River negotiators missed a mid-November
deadline, Colorado water experts ranged from disappointed to
optimistic. But they agreed on one thing: State negotiators
need to break their current impasse — whether that’s by
hiring a mediator or taking a hard look at conservation.
… Water watchers are buzzing about the potential for big
announcements at the Colorado River Water Users Association
conference in Las Vegas next month, the largest gathering of
Colorado River professionals each year.
Nearly 5.5 billion gallons of water were captured during one of
the wettest Novembers on record in Los Angeles, the LADWP said.
After a dry start to the water year, November
brought several days of rain. The city captures water
through its stormwater system, residential rain barrels and
cisterns, and expansive spreading grounds where water collects
to recharge underground aquifers. That groundwater can be
pumped and treated to meet water quality standards for homes
and businesses. The LADWP’s stormwater system has the
capacity to capture more than 27 billion gallons under average
conditions, the agency said.
What will life be like for farmers in the Russian River
Watershed after the Potter Valley Project is decommissioned and
its dams removed? “An absolute disaster,” said one
attendee of a forum held in Ukiah Monday to update the public
on the process of dismantling the Pacific Gas and Electric
Company’s hydroelectric plant in Mendocino County. … As
for which storage options might be pursued, [IWPC legal council
Scott] Shapiro said that was not something the IWPC was
prepared to address at this point, as the first step was
“making sure the water continues to flow, the second part is
figuring out how to maximize water storage.”
The deadline for landowners in the North Kings Groundwater
Sustainability Agency (GSA) in north Fresno County is Sunday,
Nov. 30. Otherwise, well owners will be subject to a $100
penalty per well. The GSA has been on a quest to identify an
estimated 7,000 wells within its boundaries since May. … The
registry will help the agency fill “data gaps,” get a better
handle on groundwater management and demonstrate a desire to
maintain local control to state regulators. It stems from the
Sustainable Groundwater Management Act (SGMA),
which requires local agencies bring aquifers into balance by
2040.
Now that the former Motel 6 building, restaurant, and parking
lot have been demolished from the Upper Truckee Marsh in South
Lake Tahoe, planning is underway to bring this wetland back to
life. To support the next phase of this project, the Tahoe Fund
announced “A Million for the Marsh” campaign to raise the first
$1 million of private funds to help secure the public funds the
California Tahoe Conservancy will need to revive this area and
bring significant improvements to Lake Tahoe’s clarity.
The state of California has announced funding for several
salmon and steelhead recovery projects as part of a USD 87
million (EUR 75 million) investment in conservation. … The
grant funding – which was approved at the WCB’s November
meeting – will be spread across 16 projects, several of which
directly tie into the California Salmon Strategy for a Hotter,
Drier Future – a plan released by Governor Gavin Newsom in
January 2024 to coordinate the state’s response to declining
salmon populations. … The bulk of the funding – roughly
USD 71 million (EUR 61 million) – will go directly to projects
supporting salmon health and habitat in California’s rivers.
For years, farmers have struggled with water supplies.
Sometimes, because of drought. Other times, because of
government red tape. But now, they are facing a new threat that
requires all hands on deck— from laboratories to the
legislature. “The potential impact is significant,” says Kelly
Vandergon, Deputy General Manager for Operations and
Maintenance at Westlands Water District. FOX26 was there
Friday, as crews carried out maintenance on a pump near Five
Points along the California Aqueduct. As they removed the
traveling water stream pump you could see shell after shell–
Golden Mussels— attached to the pipe.
Ventura officials have warned hundreds of residents in the
Pierpont neighborhood not to use their tap water after trace
amounts of gasoline was detected in the city’s water supply
near Harbor Boulevard and Monmouth Way. … It was unclear
exactly how the gasoline may have gotten into the drinking
water supply. Over a year ago, a gas-like odor spread through
the beachside Pierpont neighborhood, prompting two evacuations
in four days. More than a week after initial reports, agencies
said they traced the source to the Sinclair gas station on
Harbor Boulevard.
Data centers are notoriously thirsty. Researchers at Lawrence
Berkeley National Laboratory have found that, in 2023, the
facilities consumed roughly 17 billion gallons of water for
their operations in the U.S. alone. But that’s only a small
part of the picture: A much, much larger share of data center
water-intensity is indirect, a byproduct of the facilities’
enormous appetites for energy. … However, new research
from Cornell University shows that there’s a way to mitigate
both the climate and water footprints of these
facilities: Build them in places with lots of wind and solar
energy.
Colorado Parks and Wildlife has expanded the area of the
Colorado River labelled “infested” with zebra mussels. The area
extends from the confluence of the Eagle River down to the
Colorado-Utah border. The designation comes after CPW sampled
four Western Slope rivers — the Eagle, Gunnison, Roaring Fork
and Colorado rivers — on Oct. 29. The Yampa River feeds the
Colorado through the Green River, and faces threats of its own,
apart from zebra mussels. …. Of the five main aquatic
nuisance species closely monitored by CPW — Eurasian
watermilfoil, New Zealand mudsnails, quagga
mussels, rusty crayfish and zebra mussels — only the crayfish
is identified in the Yampa, and has been since 2009.
… In my district in California’s Central Valley, we see
the need for massive investments in new water infrastructure to
meet the needs of our growers and disadvantaged communities,
yet we seem incapable of moving beyond the endless planning and
discussion phases. … A clear example is the Los
Banos Creek Detention Project in western Merced
County. … Instead of being fast-tracked, the project,
first proposed in 2012, has since wound its way through
separate approval processes at the U.S. Bureau of Reclamation,
California Department of Water Resources and State Water
Resources Control Board. –Written by Rep. Adam Gray, who represents the 13th
District of California in Congress.
Threats due to drought and overuse continue to threaten water
availability in the Rio Grande River Basin in Southern Colorado
and all along its entire 1,900-mile-long course. That’s
according to a new study by the World Wildlife Fund,
Sustainable Waters and various universities.
… Researchers say 52 percent of the basin’s water used
directly for human activities isn’t replenishable from
renewable sources like snow melt. The study points to irrigated
agriculture, which comprises about 87 percent of the use in the
entire river basin, combined with lower snowfall, as the
primary causes of depletion.
Colorado Parks and Wildlife wants to see more beavers back at
their historic range in the state. That’s clear from the
“overarching goal” stated in a recently released draft
strategy: “Increase beaver populations and beaver-occupied
wetland habitats in Colorado until social or ecological
carrying capacity is reached.” Those social and ecological
factors are complicated — also clear from the 125-page document
called the Beaver Conservation and Management Strategy.
… In building dams, beavers are known to affect stream
flows in a way that guards against flooding, protects
water quality by controlling debris and combats drought by
recharging groundwater.
A string of early-season storms that drenched Californians last
week lifted much of the state out of drought and significantly
reduced the risk of wildfires, experts say. … Overall,
the state is at 186% of its average rain so
far this water year, according to the Department of
Water Resources. … The [Central Sierra Snow Lab]
research station at Donner Pass has recorded 22 inches
of snow. Although that’s about 89% of normal for this
date, warmer temperatures mean that much of it has already
melted. … The snow water equivalent, which measures how
much water the snow would produce if it were to melt, now
stands at 50%.
Other weather and water supply news around the West:
Efforts to improve the revitalization of Battle Creek were
recently achieved through River Partners’ acquisition of the
historic 1,721-acre Battle Creek Ranch in Tehama County. The
acquisition was made possible through a $15.05 million grant
approved by the California Wildlife Conservation Board (WCB),
which also awarded nearly $600,000 to retire a water-right
diversion associated with the property. The goal is to restore
one of California’s most important salmon-bearing waterways,
according to WCB. The acquisition will conserve the last
unprotected lands along lower Battle Creek, which would
complete a nearly three-decade-long effort to preserve all
properties along the waterway’s 7.5-mile lower reach.
The Trump administration is struggling to head off a crisis
along the West’s most critical river, but the pollution
regulation it proposed last week could make the problems worse,
according to water experts. The EPA proposal would dramatically
restrict the number of streams and wetlands that receive
protection under the federal Clean Water Act
even though the agency itself acknowledges it would exclude
many of the mountain streams and wetlands that are the source
of more than 70 percent of the flow of the Colorado
River. … If the EPA proposal moves forward, those
diminishing supplies could face increased pollution.
Arizona Governor Katie Hobbs joined governors from Hawaii,
Montana, Idaho and Utah to talk about water, energy,
agriculture and healthcare at Western Governor’s Association’s
winter meeting in the Phoenix area on Thursday, Nov.
20. The conference brought state leaders together less
than two weeks after the seven basin states who rely on
Colorado River water failed to come to an
agreement on new management guidelines. … ”I’m sure I
would have the exact same views as Governor Hobbs if I was a
Lower Basin state,” [Utah Gov. Spencer] Cox said during the
press conference. … While Cox has pushed for resolving a new
agreement without federal intervention–despite the missed
federal deadline–Hobbs continued campaigning in favor of it.
The Department of Water Resources (DWR) has released a
comprehensive new assessment of water conveyance in the San
Joaquin Valley. … The study, an action in Governor Newsom’s
2020 Water Resilience Portfolio, finds that the top priority
for improving conveyance in the San Joaquin Valley is stopping
or minimizing land subsidence, especially near State
Water Project and Central Valley
Project conveyance facilities. This can only be
achieved over the long term by raising groundwater levels above
critical thresholds. The study also finds that repair of
existing conveyance infrastructure is more important than
expanding or building new conveyance because the region has
limited surface water supplies.
A city consultant recently discovered PFAS chemicals in the
soil and groundwater of the Livermore Municipal Airport,
spurring the regional water board to call for additional
evaluation of the site. The PFAS Investigation Report published
Oct. 13 by Geosyntec Consultants, Inc. was meant to determine
whether PFAS — an abbreviation for perfluoroalkyl and
polyfluoroalkyl substances — have been released at the airport
and whether a discharge has contributed to PFAS plumes in the
Livermore Valley Main Basin or contamination in municipal
drinking water supply wells operated by the Zone 7 Water
Agency.
