E. coli levels in the Tijuana River watershed are often 30,000
times higher than the federal standard for freshwater bodies,
according to a new report San Diego Coastkeeper released last
week. And chemicals researchers said they can’t find thresholds
for because they’re not expected to be found in water are also
being detected in the binational river. … Coastkeeper’s
findings come ahead of what could be another public health
report on the Tijuana River crisis. San Diego County announced
last week that it’s launching a second survey with the Centers
for Disease Control and Prevention (CDC). … CDC and
county volunteers conducting the survey are expected to select
households randomly Sept. 17 and 18 between 2 p.m. and 7 p.m.
and Saturday from 10 a.m. to 7 p.m.
Approximately $158.2 million of bond money approved in 2024
will pay for projects in the State Water Project and
Sacramento-San Joaquin Delta levees, according to an
announcement from state Sen. Jerry McNerney, D-Stockton. The
money was approved as part of the budget bill Assembly Bill
113, which passed the legislature in August and is on the
governor’s desk. According to McNerney’s office, the funding
comes from Proposition 4, which California voters passed in
2024. … Part of that money, $90.2 million, will go to
paying for fortification of the Delta’s aging levees, while $68
million will pay for the State Water Project’s California
Aqueduct and canals. … According to a 2025 report from
the California Department of Water Resources, the State Water
Project has suffered from underinvestment and deterioration.
People visiting parks in San Jose and other cities across
California will soon see less grass and more bark as part of an
effort to save water. Cities are making the move to the more
brown look in order to comply with Assembly Bill 1572, which
goes into effect January 1, 2027. “Basically it says cities
generally cannot use potable or drinking water to irrigate
grass that does not serve a recreational, community or public
use function,” said Ed Bautista with San Jose Parks, Recreation
and Neighborhood Services. In San Jose, sections of
non-functional turf at about 50 city parks will be replaced
with tanbark or mulch. ”We’re turning off the irrigation
in areas that are on the periphery of parks, that are not
really recreation areas that are used for sports or designated
picnic areas,” Bautista said.
Stand beside almost any mountain creek in Colorado,
and there’s a good chance no one has ever measured
how much water is flowing past your boots. Of the thousands of
small headwater streams that lace the state’s high country,
feeding its rivers, irrigating its farms, and sustaining fish
and wildlife, only a small fraction has a
streamflow gauge. For the rest, knowing whether a stream is
running high, low, or somewhere in between has traditionally
meant a trip into the field and an educated guess.
Researchers in the Department of Ecosystem Science and
Sustainability, ESS, have built a new tool designed
to close that gap. CSUFlow25, a free, publicly
available web application, lets anyone drop a pin on a Colorado
stream and get a statistically modeled estimate of how that
stream flows across the year, no gauge
or field visit required.
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.
A much-anticipated water bill brought by one of the most
powerful lawmakers on Capitol Hill became public Thursday.
Senate President Stuart Adams’s SB 211, titled “Generational
Water Infrastructure Amendments,” seeks to secure a water
supply for decades to come. It forms a new council comprised of
leadership from the state’s biggest water districts that will
figure out Utah’s water needs for the next 50 to 75 years. It
also creates a new governor-appointed “Utah Water Agent” with a
$1 million annual budget that will “coordinate with the council
to ensure Utah’s generational water needs are met,” according
to a news release. But combing through the text of the bill
reveals the water agent’s main job will be finding an
out-of-state water supply. … The bill also notes the
water agent won’t meddle with existing water compacts with
other states on the Bear and Colorado rivers.
