The Bureau of Reclamation announced Wednesday that
south-of-Delta water contractors are having their water
allocation increase from 35 percent to 40 percent of their
contracted amount. That five percent increase was
“incredibly disappointingly low” for Westlands Water
District. The big picture: South-of-Delta contractors
were initially allocated 15 percent of their contracted total
in February, but that number was boosted to 35 percent in
March. Farmers were hopeful that California’s above
average snowpack would result in a greater boost, considering
the state has had a good start to the year with precipitation.
Conservationists lost an appeal to the Ninth Circuit on
Wednesday as they attempted to force the federal government to
reconsider climate change studies in managing the Glen Canyon
Dam and Colorado River. Save the Colorado, Living River and the
Center for Biological Diversity initially asked the U.S.
Department of the Interior to consider emerging climate science
and the severe potential of climate change in updating its
management plan in 2016 for the Glen Canyon Dam on Lake Powell,
which has a water level 3,564 feet above sea level.
… [The judges] concluded that the Interior did not
violate environmental law when developing its 20-year plan for
managing water releases from the dam or the plan’s accompanying
environmental analysis.
Long-term weather models are hinting a wet storm could sweep
California in early May, but forecasters warn that people
shouldn’t arrange their plans around this potential system just
yet. On Tuesday, the National Weather Service’s Weather
Prediction Center told SFGATE that some models show the storm
could generally bring a chance of 0.5 to 1 inch of rain across
the entire state. An inch of rain is not a big deal in the
winter, but in May, it’s a little less typical.
… Weather models show the storm potentially arriving May
4, with rain chances continuing into Monday, May 6. Oravec
shared this information with a big caveat: The timing of the
storm is likely to change in the coming days, or the entire
forecast could shift.

Several environmental groups asked San Francisco on Tuesday to
reduce its diversion of Tuolumne River water. They said chinook
salmon and other wildlife suffer from the current operations,
especially the river stretch in and near Modesto. At a meeting
of the San Francisco Public Utilities Commission, the groups
urged more conservation and wastewater recycling. The agency
responded that these “single-issue activists” do not understand
the city’s needs. San Francisco secured rights in 1913 to about
an eighth of the Tuolumne, which arises at about 13,000 feet in
Yosemite National Park. Most of the water diversion is at Hetch
Hetchy Reservoir, built just inside the western park boundary
to the dismay of early preservationists.
The Biden administration announced a goal Tuesday to protect
and restore 8 million acres of wetlands over the next six years
in an effort to counter development pressures and recently
weakened federal regulations. The bold new target seeks to
reverse the ongoing loss of U.S. wetlands, which help keep
pollutants out of rivers and streams and act as a natural
buffer against flooding. Over 60 percent of wetlands now lack
protections under the Clean Water Act for the first time in
decades after the Supreme Court curtailed the law’s scope last
year. In addition to wetlands, the administration
committed to “reconnect, restore and protect” 100,000 miles of
rivers and streams nationwide by 2030, including by removing
impediments such as dams and by restoring stream banks
experiencing erosion.
Something spectacular is happening in the Golden State.
California—the fifth-largest economy in the world—has
experienced a record-breaking string of days in which the
combined generation of wind, geothermal, hydroelectric and
solar electricity has exceeded demand on the main electricity
grid for anywhere from 15 minutes to 9.25 hours per day. These
clean, renewable electricity sources are collectively known as
wind-water-solar (WWS) sources. … With the future growth
of both utility-scale and rooftop solar, however, California
will ultimately provide 100 percent WWS during summer daytime
hours as well. Solar, though, provides electricity during the
day only.
For the last 20 years, the Southern Nevada Water Authority has
been giving Las Vegas residents cash for each square foot of
grass they convert to a desert landscape. That incentive went
up just for 2024 from $3 a square foot to $5 a square foot of
grass converted. … Last year, over 12 million
square feet of grass was converted and that was when the
incentive was at $3 a square foot. Now this year at $5 a square
foot SNWA is seeing around a thousand applications each month
for the rebate program which has a budget of about $24
million.
The Del Norte City Council approved long-awaited Renovations on
the Wastewater Treat Plant (WWTP). The WWTP is operated via
contract with Jacobs Engineering. Jacobs Staff were on hand in
the audience and via Zoom to address technical questions by
councilors and the Public. The Resolution for amending the
agreement with the California State Water Resources Control
Board (SWRCB) amends the financial arrangements between the
City and the SWRCB. A second Resolution approved amending the
City budget for fiscal year 2023-24.
Emerald Bay is known for its beauty, with an island castle at
its center, and an underwater state park full of sunken boats.
But that’s not all that lies beneath the water’s surface. Two
defunct, lead-clad telecommunications cables run across the
mouth of the bay and along Tahoe’s southwestern shores. An
ongoing court battle and investigation by the Wall Street
Journal have brought the cables into the public eye. The
California Sportfishing Protection Alliance has sued AT&T
to have the cables removed, while competing studies by AT&T
and WSJ resulted in drastically different findings on whether
the lines pose any risk to the lake and its visitors.
California may be a leader in the fight against climate change,
but the state is years, even decades, behind other states when
it comes to granting environmental rights to its citizens.
While a handful of other state constitutions, including those
of New York and Pennsylvania, declare the people’s rights to
clean air, water and a healthy environment, California’s does
not. That could change as soon as November. Under a proposal
moving through the Legislature, voters would decide whether to
add one sentence to the state constitution’s Declaration of
Rights: “The people shall have a right to clean air and water
and a healthy environment.”
Fresno State is making waves in water education. The university
announced on Tuesday that it’s offering a new minor. The course
is part of a collaboration with the California Water Institute.
It will focus on water from an agricultural point of view, as
well as impacts on the environment and the effects on people
and society throughout the Central Valley, the state, and the
American West. This minor is unique because it requires
students to take classes in several different departments and
even other colleges at the university.
In the two decades to 2019, global plastic production doubled.
By 2040, plastic manufacturing and processing could consume as
much as 20% of global oil production and use up 15% of the
annual carbon emissions budget. Most of the plastic we make
ends up as waste. As plastic manufacturers increase production,
more and more of it will end up in our landfills, rivers and
oceans. Plastic waste is set to triple by 2060. Producers often
put the onus back on consumers by pointing to recycling schemes
as a solution to plastic pollution. … Our new
research found the relationship is direct – a 1% increase
in plastic production leads to a 1% increase in plastic
pollution, meaning unmanaged waste such as bottles in rivers
and floating plastic in the oceans. -Written by Kathryn Willis, Postdoctoral Researcher

In recently published research, a consortium of local, state,
and federal agencies including USGS and NOAA introduces the
Advanced Quantitative Precipitation Information (AQPI) system,
which aims to improve prediction and monitoring of
precipitation, streamflow, and coastal flooding in the San
Francisco Bay Area. Combining real-time observations with
state-of-the-art modeling, AQPI represents a significant
advancement in forecasting capability. Developed as a response
to the urgent need for better water-management tools in
California, this experimental system will bolster
decision-making processes for communities vulnerable to extreme
weather events. The Bay Area’s complex landscape, nestled
between coastal mountain ranges, has long posed challenges for
accurate precipitation monitoring.
With runoff from this year’s snow and rain boosting the levels
of California’s reservoirs, state water managers on Tuesday
announced plans to increase deliveries of supplies from the
State Water Project to 40% of full allotments, up from 30% last
month. The increased allocation, which had been widely
expected, means that suppliers serving 27 million Californians,
as well as some farming areas, will have substantially more
water available to use and store this year. But the Department
of Water Resources also said officials have had to limit
pumping from the Sacramento-San Joaquin River Delta this year
because of environmental protections for native fish.
Farmers in the critically overdrafted Tulare Lake Subbasin in
the San Joaquin Valley are bracing for escalating costs as
state and local agencies assess fees on wells and groundwater
pumped. For the first time, the California State Water
Resources Control Board last week placed the subbasin on
probationary status as part of regulations under the state’s
landmark 2014 Sustainable Groundwater Management Act, or SGMA.
… Kings County Farm Bureau Executive Director Dusty Ference
said new state and local groundwater-related fees will impact
farmers and communities.
Last fall, UC Riverside’s Dr. Hoori Ajami co-authored a study
looking at how long-term droughts are impacting river flows
across the US. We asked Dr. Ajami and The Nature Conservancy’s
lead river scientist, Dr. Bronwen Stanford, to tell us about
the study and its implications. First, what is a “baseflow
drought” and how is it distinct from a precipitation drought?
Hoori Ajami: Water in a stream has two sources: precipitation
and groundwater. “Baseflow” is groundwater’s contribution to a
stream’s flow. We were specifically interested to see how a
river’s baseflow changes after a precipitation drought. …”
From the Sacramento River to the coast, salmon populations have
struggled to survive, and fishing for salmon in California has
been canceled for the second season in a row, marking the third
season in the state’s history a fishing ban has been in place.
The heart of the problem: dams and climate change. …
Steve Lindley, director of NOAA’s Fisheries Ecology Division at
the Southwest Fisheries Science Center, said
the removal of dams from Oregon to Northern
California on the Klamath will help with survival even if
drought returns.
Perfluoroalkyl and polyfluoroalkyl substances, known as PFAS,
can be found in those items and hundreds of other household
products. the chemicals have made their way into our showers,
sinks and drinking glasses — a 2023 study detected PFAS in
nearly half of the nation’s tap water. … For the first time,
the Environmental Protection Agency is regulating PFAS. This
month, the E.P.A. announced that it would require municipal
water systems to remove six forever chemicals from tap
water. Lisa Friedman, a reporter on the Climate desk at
The New York Times, wrote about the new rules.
When Californians voted for Proposition 1 in 2014, they had
every reason to expect sound investments in climate-resilient
water projects. And all but one of the projects selected to
receive the proposition’s $2.7 billion in water supply funding
fulfill those criteria.They replenish groundwater basins and
enhance the storage capacity of existing reservoirs to better
withstand droughts — benefits that are realized by all people
across the state. Unfortunately, the one project that does not
measure up — the Sites Reservoir Project — would be publicly
funded to the tune of nearly $900 million. -Written by Max Gomberg, a former California
State Water Resources Control Board climate adviser and a
senior policy consultant and board member of the California
Water Impact Network.
