Water for a thirsty Las Vegas has been building up over the
past month and a half and snowpack levels are 11% above normal
on April 1 — the date that snow normally peaks as warmer
weather begins to set in. … Two consecutive years above
normal snowpack levels is bucking the trend reported in a
July 2023 study that showed runoff has declined 10.3% over
the past 140 years because of increasing hotter
temperatures. Last year’s wet winter helped refill Lake
Mead and Lake Powell, the nation’s two largest reservoirs. But
they are still low. Lake Mead is currently at 37% of capacity,
and Lake Powell is at 33%.
Fog is central to life in California. … But climate
change is going to disrupt this quintessentially Californian
weather experience. We asked Todd Dawson, a scientist who has
long studied the relationship between fog and redwoods, to
divine the future of fog for us. Why does fog occur in
California, and why is it so important to the state’s
ecosystems? … Fog also provides an enormous, critical
water subsidy that sustains many coastal systems. Our coastal
fog has a high water content, so when it strikes surfaces such
as redwoods and grasses, it drips into the ecosystem. It
represents anywhere from 30–40% of all the water coastal
redwoods get each year.
The Solano County Water Agency will provide a presentation to
the Fairfield City Council in the wake of the draft Bay-Delta
Water Quality Control Plan that could see water allocations for
Solano County communities from Lake Berryessa cut
significantly. … The State Water Quality Control Board has
noted that diminished [flows in the Sacramento and San Joaquin
river watersheds] are harming fish habitats and are detrimental
to the water system as a whole ecologically.
…Gatorade, mayonnaise and Fireball bottles, soccer and golf
balls, Nerf bullets, ballpoint pens, hypodermic needles, nasal
sprays—you name it and Carol Shumate, the clean team director
at Russian Riverkeeper, has seen it. Not just here, [in Santa
Rosa Creek], but all over [Sonoma County]. … Despite
calls from environmentalists, legislators and scientists,
plastic has become more prevalent, not less.
The basin depends on 7,650 acre feet of natural inflow each
year but users pump out nearly 28,000 acre feet annually,
creating a severe overdraft. As the Authority has worked to
comply with the Sustainable Groundwater Management Act (SGMA)
to bring the basin into balance numerous legal actions have
erupted. The Authority restricted pumping for most users. The
U.S. Navy, which operates the China Lake Navale Weapons Base in
the basin, got the lion’s share of pumping. While agricultural
users, such as Mojave Pistachios, which started planting in the
high desert around 2010, received zero pumping allocation.
Envisioned as a haven for shoppers, golfers and globetrotting
sightseers, a $2 billion hotel and mega-resort under
construction in southwest Utah is already providing a home for
one of the state’s most endangered species. Black Desert
Resort is a 630-acre resort taking shape in Ivins about 8
miles northwest of St. George. In collaboration with
the Utah Division of Wildlife Resources and Utah Tech
University last week, resort officials released 400 Virgin
River chub into one of Black Desert’s six
lakes. The Virgin River chub, a silvery fish that
ranges in size from eight-to-18 inches, is protected under the
federal Endangered Species Act. The fish species, which is
native to the Virgin River, is under threat from habitat loss,
drought and the introduction of illegal fish species.
As mining operations ramp up across Arizona, two massive
projects facing opposition from environmental groups and Native
American tribes have public comment deadlines in the coming
weeks. The Arizona Department of Environmental Quality is
accepting comments on the proposed Resolution Copper project
near Superior through April 7 and for the Copper World project
in the Santa Rita Mountains, about 30 miles south of Tucson,
through April 10. … Oak Flat sits over one of the
largest remaining copper deposits in the world. The mine would
sink more than 7,000 feet into the ground, where temperatures
reach 180 degrees Fahrenheit. It would require large quantities
of water for cooling, dust control to remediation of mine
waste.
Federal salmon overseers say Oregon Coast Chinook face a low
risk of extinction, according to a recently concluded deep dive
into the health of runs stretching from the Necanicum in the
north to the Elk and Sixes in the south. It’s not the
final word on whether an Endangered Species Act listing is
needed or not, but the 195-page status review does
represent an assessment by the National Marine Fisheries
Service’s Northwest Science Center in response to a petition
filed in 2022 to list the stock and will be a relief to
fishermen and salmon managers. … However, the news
wasn’t as good for Chinook in the Southern Oregon and Northern
California ESU, which stretches from Bandon to the Klamath
River. Even as the overall population is also at low risk of
extinction, key components aren’t doing as well, raising the
risk for the entire stock.
Marin County and Novato are disputing a state water board’s
contention that they are doing too little to prevent the
discharge of fecal bacteria into the Petaluma River. The San
Francisco Bay Regional Water Quality Board notified both the
county and Novato in January that they are out of compliance
with a program that it adopted in 2019 to reduce the level of
fecal bacteria in the river. Both jurisdictions, however,
contend that they are not required to comply with the program
because the scheme has not yet been incorporated into their
municipal storm sewer system permits, which are issued by the
State Water Resources Control Board.
Five possible alternatives to the tire antidegradant 6PPD have
been identified, following a comprehensive preliminary analysis
completed by a consortium of 30 tire manufacturers March 25.
California’s State Water Board is wrestling with what terms to
set for water conservation regulation for urban areas. This
regulation implements state policy designed to Make
Conservation a California Way of Life. But the only way to make
that vision equitable is to ensure the needs of low-income
communities are taken into account. Unfortunately, the Water
Board is considering making it too easy to slow-walk
investments in conservation, not only in low-income
communities, but also in wealthy places like Beverly Hills that
use significantly more than their fair share. The proposed
regulation currently under consideration means that 72% of
Californians will not need to save a single additional drop
until 2035. -Written by Kyle Jones, Policy & Legal Director
at the Community Water Center.
In the Records Room of the CalEPA building in Sacramento are
some of the most important documents in the entire state of
California. Some date back to 1914. “Our files are organized in
ascending order,” explained Matthew Jay, an analyst with the
State Water Resources Control Board. “The oldest documents are
at the bottom and so you can see that some of the stuff is all
typewritten and in a lot of cases, handwritten.” … The
papers are what’s known as water rights – the backbone of life
in California and its multitrillion dollar economy. Water
rights are official documents validating who has the authority
to take water, from where, and how much of it.
With chronic water shortages afflicting the Colorado River,
discussions about how to cut usage have increasingly focused on
a thirsty crop that consumes an especially large share of the
river’s water: hay that is grown to feed cattle and produce
beef and dairy products. In a new study, researchers found that
alfalfa and other cattle-feed crops consume 46% of the water
that is diverted from the river, accounting for nearly
two-thirds of agricultural water use. The research also shows
that agriculture is the dominant user of Colorado River water,
accounting for 74% of the water that is diverted — about three
times the combined usage of all the cities that depend on the
river. The study presents the most detailed analysis of its
kind to date, including extensive data on where the river’s
water goes across seven Western states and northern Mexico.
… Over the next several years, Pacific Gas and Electric Co.,
the current owner of the Potter Valley Project, is planning to
retire the hydroelectric plant and remove two dams on the Eel
River that provide water for the facility. With power
production shut down, tunneling water into the Russian River
won’t be necessary. … The Potter Valley Project provides a
portion of the water supply for large swaths of Mendocino and
Sonoma counties. … Scores of vineyards here are tethered
to water rights that are subject to restriction when river
levels drop. During the recent drought, hundreds of
water-rights holders were forced to stop pumping — a
scenario many believe was a preview of a future where the Eel
River doesn’t continue to supplement the Russian.
As winter conditions wind down, the beginning of April is
always the most important time for California’s water managers
to take stock of how much snow has fallen in the Sierra
Nevada. This year, something unusual happened. After years
of extreme drought and several very wet flood years, the Sierra
snowpack, the source of one-third of the state’s water supply,
is shockingly average this year: 104% of normal on
Friday. And more is on the way.

… The season typically runs from May to October, but
California Chinook salmon populations have declined so severely
in recent years that fishery authorities are considering
whether to adopt severe restrictions this season or impose a
ban on fishing altogether for the second consecutive year.
… [Many salmon fishers lay] much of the blame on
California water managers, who [they say] send too much
water to farms and cities and deprive rivers of the cold flows
salmon need to survive.
A generational issue for the families living in San Lucas
continues as they’ve gone decades without drinking water. Soon
federal, state, and local leaders will secure nearly a million
dollars to build a pipeline to King City. … Plants not
growing, animals dying, young children unable to bathe, this is
the reality for those living in the unincorporated South
Monterey County town of San Lucas.
Attorney General Kris Mayes told La Paz County residents she’s
considering a lawsuit to stop corporate farms from overpumping
groundwater there and in Cochise County. Her investigators are
seeking examples of harm such as dry wells, cracked foundations
and dust on which to build a possible case using the state’s
nuisance laws, she said Thursday.
[Denise] Moreno Ramírez wasn’t surprised when she heard an
Australian mining company, South32, planned to open a
manganese, zinc, lead and silver operation in the same area
where her family had worked. … But this latest proposed mine
was alarming, she said, because Biden is fast-tracking
it in the name of the energy transition – potentially
compromising the mountain’s delicate ecosystems, many of which
have begun to be restored as mines have shut
down. … A growing network of Arizona residents say
that allowing the mine to proceed as planned could introduce a
grave new layer of environmental injustices.
…Conservationists say they worry that South32 is seeking to
use water irresponsibly amid long-term drought.
