Drought or no drought, California water regulators are pushing
ahead with a new conservation policy that could force some
communities to cut water use upward of 30% permanently — though
on more lenient terms than originally proposed. The
first-of-its-kind regulation is intended to help the state
confront chronic water shortages as climate change makes for
hotter, drier weather. The initial draft of the regulation,
released last year, was widely criticized for asking roughly
400 cities and water agencies to cut back too much too quickly.
The cost of compliance was also a concern. Acknowledging the
burden, the State Water Resources Control Board on Tuesday
unveiled a revised set of rules that would allow some
communities to use more water than originally planned as well
as extend deadlines for meeting the conservation mandates.
Across the parched West, there are signs the region’s
decades-long population and housing boom is confronting the
realities of dwindling water supplies. These have come in
recent months from court rulings and executive edicts alike, as
states crack down on the potential for new users to draw from
already oversubscribed aquifers and surface waters. The
skeleton of a would-be subdivision outside Las Vegas
illustrates the coming constraints, stymied by a lack of water
to support the new community. Water shortages also forced
difficult decisions in other places, such as new restrictions
in the Phoenix suburbs and a Utah town that halted all new
construction for more than two years until it could secure a
new well.
Still water in the Tijuana River Valley reflects the chirping
birds who live there, giving the impression it is as nature
made it — until you see the floating trash and smell the
stagnant, polluted water. For decades, activists tried to clean
up the Tijuana River’s watershed as it flowed from Tijuana into
San Diego’s coastal waters, which are contaminated with both
human and industrial waste. A recent study from the Scripps
Institution of Oceanography found that coastal pollution is
also transferring to the air. “This is nothing short of an
environmental and public health crisis, and it has been made
worse by the fact that California companies are part of the
problem,” said State Senator Steve Padilla Monday, while
announcing SB 1178, a bill to address cross-border pollution.
California citrus farmers are finding ways to adapt to the
changing landscape, as the challenges of this production year
come to light. Amid the harvest of California navels,
mandarins, and other specialty varieties, two industry leaders
share their perspectives on the prospects of the industry.
… Jim Phillips, President and CEO of Sunkist, expressed
similar concerns regarding production but also emphasized the
current state of affairs regarding the Sustainable Groundwater
Management Act (SGMA). California citrus farmers need the
support of the legislature regarding water access, as the issue
is outpacing almost every other concern for growers, said
Phillips. Both Bates and Phillips noted that the
substantial amount of rainfall and snowpack over the past two
winters are supporting growers in the fight for water access.
A dozen tire companies are asking a California federal judge to
toss a suit claiming a rubber additive is harming protected
salmon, arguing that the litigation stretches the Endangered
Species Act “beyond its breaking point” and that regulation of
the substance belongs with the U.S. Environmental Protection
Agency, not in courts.
Photos recently shared by the National Weather Service (NWS)
office in Las Vegas revealed a key difference in snowpack
levels between this year and last year. After years of drought,
an abnormally wet winter produced more than a dozen atmospheric
rivers that brought a deluge of rain and snow to the region. A
similarly wet winter has happened this year, with multiple
atmospheric rivers bringing torrential downpours to California,
Nevada, and other western states. However, despite the
storms, the region’s snowfall hasn’t been as impressive as it
was last year.
Giant sequoia trees, imported to the UK 160 years ago, are
flourishing despite the dramatically different climate to their
native California, a new study has found. The huge trees, which
are declining in numbers in California due to increasing heat,
are now adapting well to the UK’s climate and growing taller, a
study conducted by UCL researchers says. “The growth here
in the UK seems to be suited to our wetter climate, so there’s
far less chance of water stress here than in the Sierras in
California,” lead author of the study and professor of
geogrpahy, Mat Disney, told The Independent.
A new consulting firm is taking over construction management
services for the city’s Lake Wohlford Dam Replacement Project.
The Escondido City Council unanimously approved hiring GEI
Consultants, Inc. for $12.9 million to continue construction
management services for replacing the 129-year-old dam. Lake
Wohlford Dam was first constructed with earth and rock in 1895
to a height of 76 feet. About 30 years later, the dam was
raised to 100 feet using a slurry hydraulic fill process. In
2007, during a routine seismic evaluation of the dam, the
California Division of Safety of Dams determined that the
hydraulic fill section could liquefy and fail in the event of a
greater than 7.5-magnitude earthquake along the Elsinore Fault.
In response, the city lowered the water level of Lake Wohlford
to prevent surpassing the original dam height of 76 feet.
California State Parks’ Division of Boating and Waterways (DBW)
today announced the availability of grant funding to prevent
the further spread of quagga and zebra mussels into
California’s waterways. Funded by the California Mussel Fee
Sticker (also known as the Quagga Sticker), the Quagga and
Zebra Mussel (QZ) Infestation Prevention Grant Program expects
to award a total of up to $2 million across eligible
applicants.
A new study by Cal State Fullerton researchers shows evidence
of two epic floods that occurred within the past 500 years in
Southern California during the Little Ice Age. Their
research is the first-ever, land-based, flood-event evidence
from 1450 to 1850 — a documented period of above-average
wetness in Southern California, said Matthew E. Kirby,
professor of geological sciences. According to scientists,
floods — not earthquakes — represent California’s single most
significant socioeconomic natural hazard risk.
… Climate models predict that the frequency of
large flood-producing precipitation events will increase in the
21st century due to climate change.
A rusty red color in Lake Merritt that left lake stewards
scrambling to sample the water on Mar. 7 has tested positive
for the same algae that caused the devastating harmful algal
bloom in 2022. On Friday, lake stewards sent water
samples to labs run by the California Department of Public
Health and San Francisco Bay Regional Water Control Board.
Unofficial field testing initially detected no harmful algae.
However, lab testing confirmed over the weekend the presence of
Heterosigma akashiwo, a type of algae often associated with
harmful blooms. Harmful algal blooms, or HABs, occur when
certain types of algae grow rapidly and release toxins, lower
oxygen levels, and cause other changes in water quality that
can kill fish and other marine creatures.
The Friant-Kern Canal was called out specifically as one of the
reasons the state should take over pumping in the Tule
groundwater subbasin in Tulare County. The recommendation was
contained in a recently released staff report to the Water
Resources Control Board. While the report stated groundwater
management plans covering the subbasin didn’t adequately
address subsidence and continued depletion of the aquifer and
degradation of water quality in general, it also noted the
significant harm to the Friant-Kern Canal, which brings water
152 miles south from Millerton Lake to Arvin. Excessive
overpumping caused land beneath a 33-mile stretch of the
Friant-Kern Canal to collapse, creating a sag that reduced the
canal’s carrying capacity south of Pixley by 60%.
California’s fishing industry is bracing for another bad year
as federal managers today announced plans to heavily restrict
or prohibit salmon fishing again, after cancelling the entire
season last year. The Pacific Fishery Management Council
today released a series of options that are under
consideration, all of which either ban commercial and
recreational salmon fishing in the ocean off California or
shorten the season and set strict catch limits. The council’s
decision is expected next month; the commercial season
typically begins in May and ends in October. … [P]opulations
are now a fraction of what they once were — dams have
blocked vital habitat, while droughts and water diversions have
driven down flows and increased temperatures, killing large
numbers of salmon eggs and young fish.
In California and across the country, household water rates
have been rising as utilities invest to upgrade aging
infrastructure, secure future supplies and meet treatment
standards for clean drinking water. As monthly water bills
continue to increase, growing numbers of customers have been
struggling to pay. New federal legislation would establish a
water assistance program to help low-income families pay their
bills and prevent shutoffs of water service. The bill,
introduced by Democratic Sen. Alex Padilla, would make
permanent a federal program that Congress authorized in 2020
during the COVID-19 pandemic. The program provided more than $1
billion in assistance, but it’s expiring.
Monday marked a key cutoff time by which Colorado River states
had been tasked with proposing a consensus-based plant for
long-term water conservation in the overtaxed system. But
with the arrival of that deadline, set by the Department of the
Interior’s Bureau of Reclamation, no such agreement was on the
table. Instead, the river system’s two main contingents — the
Upper and Lower basins — submitted their own competing
plans. The proposals pertained to an upcoming update of
the rules — known as the 2007 Interim Guidelines for Lower
Basin Shortages — that govern where, when and how much the
seven basin states must conserve water from the 1,450-mile
river.
California has set ambitious climate goals, including phasing
out the use of fossil fuels and becoming carbon neutral by
2045. Our guest today is here to talk about the role nature can
play in meeting those goals. Laurie Wayburn is the co-founder
and president of the Pacific Forest Trust and the chair of the
California Natural and Working Lands Expert Advisory Committee.
She was also the lead author of a recent report suggesting the
state should invest “as much in nature-based climate solutions
as it has in clean energy and transportation.” With proper
forest management, California could capture 400 million tons of
carbon each year, lower wildfire risk and vastly improve flood
protection in the state.
Just south of Dos Rios Ranch, a much-praised effort at river
restoration, another such project is taking root. It will add
about 380 acres of floodplain and other habitat to the 1,600
acres at Dos Rios. They are near the confluence of the Tuolumne
and San Joaquin rivers, about eight miles southwest of Modesto.
The state-funded project, totaling about $20.8 million, is on
the former Hidden Valley Dairy. Annual feed crops are giving
way to oaks, cottonwoods, willows and other native plants. The
floodplain will take on high river flows that otherwise could
threaten nearby Grayson and downstream towns. The standing
water could recharge the aquifer below for use during droughts.
The place could offer food and shelter to fish, birds, mammals
and other creatures.
As floodwaters receded from the streets of southeastern San
Diego on Jan. 22, two things began to happen. Several local
nonprofits — not trained in disaster response — set up a victim
assistance center at the Jackie Robinson Family YMCA. At the
same time, county and city officials had a series of extreme
miscommunications that delayed the opening of a government-run
assistance center within city limits for nearly two weeks,
according to letters obtained by Voice of San Diego.
Normally in the wake of a disaster, government officials open
what they call a Local Assistance Center near the disaster
site. These assistance centers connect survivors with
government and non-government resources. A survivor could get
anything from a new driver’s license to food or unemployment
benefits.
A powerful winter storm buried the Sierra last weekend, with
wet weather continuing for days in the Bay Area and Central
Coast. Thunderstorms Wednesday drenched Salinas, dropping
an entire inch in just 25 minutes. After historic weather last
year, intense California storms have persisted this winter,
with strong downpours causing widespread flooding in San Diego
and damaging landslides in places like Los Angeles. Many
ingredients contribute to extreme storm activity, but
scientists agree that climate change is already amping up
winter rains — and may bring even wilder weather in the
future.
Cannon Michael has been re-elected as the chairman of the San
Luis & Delta-Mendota Water Authority. The San Luis &
Delta-Mendota Water Authority announced Michael’s re-election
on Monday. The big picture: Michael is the president
of family-owned Los Banos farming operation Bowles Farming
Company. He also serves as the chair of the Henry Miller
Reclamation District, as a board member of the Water Education
Foundation and as an advisory board member of the Public Policy
Institute of California.
