The current water year, which began Oct. 1, has been wetter
than usual, with the Russian River watershed accumulating 119%
of the yearly average rainfall, totaling 49.38 inches since
October. In the past, we might have celebrated our good fortune
and watched lake levels rise only to watch much of it sent
downriver to the Pacific Ocean as reservoirs reached an
inflexible upper threshold. Today, we get to continue enjoying
that ample rainfall long after summer sunshine arrives. Grant
Davis With almost a decade of data under its belt, the Russian
River Forecast-Informed Reservoir Operations program has been
making great strides by demonstrating the viability of this
strategy to operate reservoirs more effectively using modern
technology and forecasting. -Written by Grant Davis, general manager of Sonoma

Insurers in California have sounded the alarm: A warming
climate has dramatically raised the risk of devastating
wildfires, and with it the cost of providing coverage. But now
a Peninsula lawmaker says those insurance companies should
credit the state and homeowners for the work done to reduce our
vulnerability to wildfires. State Sen. Josh Becker, a Menlo
Park Democrat, has introduced a bill that would require
insurers to consider the state’s efforts to thin flammable
brush and trees as well as property owners’ steps to make their
homes more fire resistant, such as covering vents and clearing
vegetation. Those efforts would need to be incorporated into
their risk modeling to determine coverage decisions and costs.
Four years ago, over 97% of Big Basin Redwoods State Park in
Santa Cruz County burned during the state’s worst wildfire
season in recorded history. Last year, unprecedented winter
storms caused an estimated $190 million in damages to coastal
parks. And at Seacliff State Beach, also in Santa Cruz County,
storms flooded the campground and destroyed the beach’s
historic pier. Climate change and the resulting severe
wildfires, extreme storms and rising sea levels are
increasingly threatening our beloved state parks. … To
address this unprecedented threat, we need to create
climate-resilient state parks that can prepare for, adapt to
and recover from climate impacts. -Written by Rachel Norton, the executive director
of the California State Parks Foundation.
President Biden has approved California’s request for a major
disaster declaration to support recovery efforts from a string
of February storms that drenched much of the state with
historic rainfall and mountain snow and resulted in numerous
deaths, officials announced Sunday. Nine California counties —
Butte, Glenn, Los Angeles, Monterey, San Luis Obispo, Santa
Barbara, Santa Cruz, Sutter and Ventura — will receive federal
aid as a result of the declaration, which also includes funding
for statewide hazard mitigation efforts, officials said. “

An interdisciplinary team of scientists and researchers from
University of California, Davis, are studying agave plants in
the Golden State as farmers are turning to the crop as a
potential drought-tolerant option of the future. The research
is centered on studying agave genetics, virus susceptibility,
pest control, soil management and crop productivity, said Ron
Runnebaum, a viticulture and enology professor who is leading
the team of researchers at the newly formed UC Davis Agave
Center. … Agave plants don’t require much water and
their hardy leaves are fire resistant. The crop can be used as
a fiber, distilled into spirits or converted into a sweetener.
That combination of traits could offer an alternative to
fallowing fields by switching from thirsty crops to one
requiring less water.
After being sanctioned by federal regulators for plowing up
protected wetlands on his California farm, a U.S. lawmaker is
now spearheading an effort to roll back federal water
protections — including the very same provisions that he once
paid penalties for violating. If the scheme is successful,
environmental groups say industrial polluters could more freely
contaminate wetlands, rivers, and other waters, harming both
the nation’s water resources and the communities depending on
them. It could also benefit the lawmaker spearheading the
attack, since he still owns the farm where he was found to be
destroying wetlands.
We gathered at Sierra Nevada Brewery on March 8 for our Annual
Meeting, and we continue to cherish the discussions and
insights shared during that event. Among the many highlights of
the gathering was a compelling address by Senator Alex Padilla,
whose remarks resonated deeply with our shared commitment to
safeguarding California’s water resources. Read the excerpt
from Chairman Bryce Lundberg’s introduction and watch Senator
Padilla’s address below.
Pasadena Water and Power (PWP) has launched a new multi-year
campaign called “The Ripple Effect” aimed at promoting water
sustainability and resilience in the community. Acting General
Manager David Reyes urged all PWP customers to become local
water stewards for Pasadena and the region by participating
in the campaign. “We invite every member of our
community to embrace their role as local water stewards,” said
Reyes. “Each one of us holds a vital place in shaping
Pasadena’s water future.” About one-third of
Pasadena’s water supply comes from local groundwater, with the
remaining two-thirds imported from other sources. PWP
emphasized that understanding where the community’s water comes
from helps foster a greater appreciation for
this critical resource.
Gov. Gavin Newsom has a new sales pitch for a tunnel to move
more water south from the Sacramento-San Joaquin River Delta
that past governors have tried and failed to build for five
decades. “The Delta conveyance is an adaptation project,” he
said last week in a snowy field in the Sierra Nevada, where a
winter that started out dry eventually delivered a
just-above-average snowpack that will soon melt into the
Sacramento River and its
tributaries. … Long-skeptical Delta lawmakers
aren’t convinced by the latest rationale. “He’s searching for a
reason,” said Representative John Garamendi, a Democrat
from the western part of the Delta.
California lawmakers want to establish the state’s position on
environmental health, taking a first step Monday in their
proactive approach to ensure processes for the state’s
environmental management remains secure, regardless of any
federal changes. … The Los Angeles Democrat is
propositioning a constitutional amendment that would enshrine
into law the Californian’s right to clean air, water and the
environment. Assembly Constitutional Amendment 16,
authored by Bryan, passed Monday out of the Assembly Natural
Resources Committee and into his chamber’s Appropriations
Committee. It must pass both houses by at least two-thirds and
then secure a majority vote at the polls.
Acronyms are so prevalent in the water industry that stringing
several together can form an impressive-sounding
sentence. That’s exactly what Hanford High School junior
Morgan Carroll did at an April 5 workshop in Sacramento called
Water 101 put on by the Water Education
Foundation. After winning a game of bingo no
less. The bingo game kept the audience of water managers and
government and nonprofit employees on its toes during a talk on
what could be a very dry topic, especially after lunch: The
role of regulatory agencies in state and federal water law.
… Part of being on the team is keeping tabs on current
events in the water industry. Students subscribed
to Aquafornia, the foundation’s daily
news summary, and found out about the workshop that way.
… This marked the second year in a row with above-average
snowfall and was a huge turnaround from conditions at the
beginning of 2024, when the snowpack across the state was
barely a quarter of the historic average. … The
relationship between snowfall and climate change is not as
simple as it might first appear. Though rising temperatures
will cause some would-be snow to fall as rain, this is partly
balanced out by the fact that precipitation will become more
intense overall, since warmer air can hold more water vapor.
Some parts of Alaska and Northern Canada have
seen increases in snowfall over the last 40 years; in
these frigid locales the amount of snow is more limited by cold
weather, which decreases the amount of moisture in the air. -Written by Ned Kleiner, a scientist and catastrophe
modeler at Verisk.

Microplastics are tiny, nearly indestructible fragments shed
from everyday plastic products. As we learn more about
microplastics, the news keeps getting worse. Already
well-documented in our oceans and soil, we’re now discovering
them in the unlikeliest of places: our arteries, lungs, and
even placentas. Microplastics can take anywhere from 100 to
1,000 years to break down and, in the meantime, our planet and
bodies are becoming more polluted with these materials every
day. Finding viable alternatives to traditional
petroleum-based plastics and microplastics has never been more
important. New research from scientists at the University of
California San Diego and materials science company Algenesis
shows that their plant-based polymers biodegrade — even at the
microplastic level — in under seven months.
In late March the Siskiyou County Board of Supervisors
proclaimed a local emergency related to concerns about heavy
metals like arsenic and lead being present in the Klamath
River. It was prompted by the ongoing removal of four
hydroelectric dams on the river. … Matt St. John, an
environmental program manager with the North Coast Regional
Water Quality Control Board, said it was expected that you’d
also have high metals concentrations. “Those metals
concentrations are not a threat to public health. It’s okay to
touch the water with those type of concentrations. And no water
in the state of California should be drunk without any without
treatment. And so, the Klamath River isn’t a source of drinking
water without treatment of that water.”

The Little Colorado River has a brilliant turquoise-blue color
due to the calcium carbonate minerals suspended in the water.
Travertine, a chalky limestone that settles out of the water
and coats the riverbed with a white hue, adds to the river’s
amazing color. The Little Colorado River can be divided
into the upper and lower reaches, with the boundary between the
two marked by a series of travertine waterfalls. The river is
one of the last remaining places where you can find the
endangered humpback chub. Science Moab talked with Phoebe
Brown, a river guide and researcher who as an undergraduate was
part of a larger study looking at the growth rates of the
humpback chub.
Zimbabwe declared a state of disaster Wednesday over a
devastating drought that’s sweeping across much of southern
Africa, with the country’s president saying it needs $2 billion
for humanitarian assistance. The declaration was widely
expected following similar actions by neighboring Zambia and
Malawi, where drought linked to the El Nino weather phenomenon
has scorched crops, leaving millions of people in need of food
assistance. … [President Emmerson Mnangagwa] appealed to
United Nations agencies, local businesses and faith
organizations to contribute towards humanitarian
assistance. El Nino, a naturally occurring climatic
phenomenon that warms parts of the Pacific Ocean every two to
seven years, has varied effects on the world’s weather. In
southern Africa, it typically causes below-average rainfall,
but this year has seen the worst drought in decades.
Canals in California may soon feature a new look — solar panel
canopies, designed to stop evaporation and soak up the sun’s
rays, created under a new project funded with help from the
federal government to boost green energy
infrastructure. Governor Gavin Newsom joined staff from
the U.S. Bureau of Reclamation on Thursday to highlight a new
“solar-over-canal” project along one of the state’s primary
aqueducts. The pilot project proposes placing a solar canopy to
“float” over a major waterway as a source of renewable energy
that can also prevent loss of precious water through
evaporation. Adam Nickels, Deputy Regional Director at the
Bureau of Reclamation, said that the Biden Inflation Reduction
Act helped make it possible to pick a portion of the
Delta-Mendota Canal for placement of a solar panel in Merced
County.
