Devastating floods are almost annual occurrences in the West and
in California. With the anticipated sea level rise and other
impacts of a changing climate, particularly heavy winter rains,
flood management is increasingly critical in California.
Compounding the issue are man-made flood hazards such as levee
stability and stormwater runoff.
The biggest storm of the season is barreling down on Northern
California. The Sacramento region could see up to 3 inches of
rain this week – perhaps doubling the amount of rain we’ve
received for the entire winter season – as an extreme storm
arrives Tuesday afternoon. The cold, wet system will bring
dangerous winds to the region, localized flooding and up to 80
inches of snow – yes, that’s nearly 7 feet – to the summits on
Interstate 80 and Highway 50.
Our 2020 Water Leaders class completed its year with a
report outlining policy recommendations for adapting California
water management to climate change. The class of
23 up-and-coming leaders from various stakeholder groups
and backgrounds – engineers, attorneys, planners, farmers,
environmentalists and scientists - had full editorial
control to choose recommendations.
Winter weather is finally arriving in Northern California. And
after weeks of dry, warm conditions and growing drought

After 10 days of protests, Britain’s Parliament did a
surprising thing: Its members approved a proposal to declare a
state of emergency in response to the rapidly overheating
planet. And while the U.K. was the first country to do so, it
wasn’t the last. Today, at least 38 countries around the world
— including the whole of the European Union, Japan, and New
Zealand — and thousands of towns, cities, and counties have
issued some kind of resolution declaring climate change a
crisis. … A week into his term, President Joe Biden is
already under pressure to do the same.
The U.S. Federal Emergency Management Agency (FEMA) estimates
that around 13 million Americans are living within a 100-year
flood zone. But over the last few years, researchers have found
that the government’s estimates are far lower than the ground
realities…. In a study published in the
journal Land Use Policy, researchers estimated that by 2050,
the number of houses in high-risk wildfire zones might increase
by nearly one million in California alone.
Baltimore may be a continent away from San Francisco, but the
coastal cities have at least one thing in common: rising seas.
Both are seeing more flooding, more shoreline erosion and more
battered infrastructure, and both want the oil industry to pay
for the damage. They blame fossil fuels for the global warming
that’s causing sea level rise. On Tuesday, Baltimore will lead
the campaign to recoup billions of dollars from oil companies
in a case before the U.S. Supreme Court.
On Wednesday, Los Angeles County officials released their
preliminary master plan for the river “reimagined” to
support both ecosystems and people who live along [the LA
River's] 51-mile corridor. … The long-awaited plan
— the result of five years of input from community residents,
organizations and people like renowned architect Frank Gehry —
will provide a foundation as the region balances its duty to
protect properties from flooding with the need for more access
to natural environments.
Dams built long ago to control floods or ease river transport
are gaining attention as a potential zero-carbon electricity
source in the US, as environmentalists and the hydropower
industry drop their longstanding antagonism in the face of
climate change. Hydroelectricity is like wind, solar and
nuclear power in that it emits no planet-warming carbon
dioxide, yet hydro capacity has not grown for decades after big
dams became impossible to build.
Large swathes of land in densely populated parts of the world
are subsiding rapidly as a result of groundwater depletion.
Paired with rising sea levels caused by global warming, this
could place many coastal cities at risk of severe flooding by
California has lost more than 90% of its wetlands since the
arrival of European settlers. Wetlands play an increasingly
crucial role in absorbing excess water and protecting coastal
and inland communities from flooding. They also provide
critical habitat for wildlife, including a variety of species

blinking out of existence…. we’ve identified three critical
lessons California has to offer the world to improve
restoration on a global scale… -Written by Julie Rentner, president of River Partners, and

Increasingly strong storms are responsible for more than a
third of the nation’s flood costs, swelling the tab by billions
of dollars a year as climate change continues to fuel more
extreme weather, according to new research at Stanford
University. The research, which is among the first to put a
price tag on heavier rainfall, found that the changing weather
is responsible for $75 billion of the cumulative $199 billion
of U.S. flood damage between 1998 and 2017. … Many of
the losses over that period were in California.
Water levels at the coastal mouth of the Russian River had
declined by late Thursday afternoon, eliminating the threat of
flooding in the town of Jenner, according to a release from
Sonoma Water, the county water agency. High waves pounded the
Sonoma Coast for days, creating a large mound of sand that
sealed the mouth of the river. The waves’ intensity initially
kept Sonoma Water from sending a heavy equipment operator to
dig a channel that would release the water from the river into
The Federal Emergency Management Agency has calculated the risk

By burning and brushing, nurturing important plants and
keeping lands around their homes clear of dead brush and
debris, Native peoples carefully stewarded the lands to sustain
the biodiverse ecologies California is known for. Their
work resulted in a richly productive landscape that provided
food and habitat for not only humans but many land, air and
water animals. That included the salmon, a staple of tribes in
the West for millennia. All that changed when California became
a U.S. state in 1850.

“King tides are about one-to-two feet higher than an average
tide, and it turns out that is about what we expect to see in
California in the next few decades from sea level rise,” said
Annie Cohut Frankel of the California Coastal Commission. “We

our public beaches, our beach access ways, wetlands, roads and
other coastal infrastructure.”
Whatever came down in the first rains of the season was a mere
drop in the bucket. The precipitation, the first for the rain
year that began Oct. 1, measured .15 inches in downtown
Sacramento, according to the National Weather Service. That
puts the city at 8 percent of normal for rainfall this year,
according to weather service records… A new storm system

A marine construction barge that apparently became stuck in the
mud at low tide in the Petaluma River on Saturday was inundated
by the rising tide overnight, becoming partially submerged and
leaking fluids into the tidal slough… Moving the barge out of
the navigation channel was expected to be a long-term
challenge, and a problem for large boats just starting to use
the river again after its recent, long-awaited dredging.
Scientists expect flooding to get worse because weather
extremes are growing as the climate crisis worsens globally,
said UCLA Climate Scientist Daniel Swain. … Waiting to
systematically address flooding issues, like California’s done
with wildfire, could mean breaching of levees, Central Valley

Burning rice straw after harvest was a traditional and
economical practice that was phased out in 2000. … The side
effect is it has created millions of acres of seasonal wetlands

when they are in synch, we get severe drought or inundation.
Wildlife in the upper Putah Creek watershed was devastated by
the LNU Complex Fire, which started on Aug. 17, was finally
extinguished on Oct. 2, and grew to be the fourth largest in

little support from local agencies, recovery is expected.
Judith Marshall joined the corps’ Portland office in 2011 to
manage several projects, including the agency’s 13 dams in the

concerns to her supervisors. Then she was harassed and bullied.
Now Marshall is blowing the whistle.
When driving over the Yolo Bypass in the winter, one can’t help
but notice the flooded fields. … Historically, the area used
to be wetlands and floodplain habitat, but now, farmers grow
rice there. After harvest, the fields are flooded to not only
help decompose the leftover rice straw but also, as a surprise
to many, recreate a surrogate habitat for many area wildlife,
most notably birds.
Recognizing the central role that atmospheric rivers play in

and their impact on the state’s water reservoirs.
The future of our existing dams, including 2,500 hydroelectric
facilities, is a complicated issue in the age of climate
change. Dams have altered river flows, changed aquatic habitat,
decimated fish populations, and curtailed cultural and treaty
resources for tribes. But does the low-carbon power dams
produce have a role in our energy transition?
Last year, the U.S. Army Corps of Engineers, which maintains a
database of all the nation’s dams and their risk levels, raised
the risk classification for the Mojave Dam in San Bernardino
County, California, to high. The 200-foot-high earthen dam was
built in 1971 and, if it fails, threatens communities as far
away as 140 miles.
In a review of Feather River fall-run Chinook salmon in
September 2019, I described their status through the 2018 run
and expressed optimism for the 2019 run. My assessment proved
overly optimistic, as the 2019 run numbers came in lower than
expected. The lower-than-expected returns appear to be the
consequence of the 2017 Oroville Dam spillway failures.
After the river was concretized, Indigenous People, activists,
and environmental organizations demanded the restoration of the

California has experienced record-breaking wildfires in 2020
with more than 4 million acres burned, increasing the risk of
flash flooding along with mud and debris flows to communities
and homes downslope of burn areas. The impacts caused by
wildfires can be drastic when it comes to flood risk.
Radically transformed from its ancient origin as a vast
tidal-influenced freshwater marsh, the Sacramento-San Joaquin
Delta ecosystem is in constant flux, influenced by factors
within the estuary itself and the massive watersheds that drain
though it into the Pacific Ocean. Lately, however, scientists
say the rate of change has kicked into overdrive…
Five California Conservation Corps (CCC) crews are assisting
Butte County Public Works and Department of Water Resources in
making sure that the watershed is protected from potential rain
water run-off from homes burned in the North Complex Fire.
What geologists call vertical land motion—or subsidence and
uplift—is a key reason why local rates of sea level rise can
differ from the global rate. California offers a good example
of how much sea level can vary on a local scale. “There is no
one-size-fits-all rule that applies for California,” said Em
Blackwell, a graduate student at Arizona State University.

Contra Costa County Flood Control Division officials told the
Oakley City Council recently that they’re still assessing the
issues of concern caused by beavers that built a dam in an area
of Marsh Creek near Creekside Park earlier this year. At the
time, the city and county received a lot of backlash from the
community and beyond because the county’s answer to the problem
was to kill two beavers that built the dam.
The fires burned thousands of square miles of land and left
scorched and barren hillsides vulnerable to an especially
dangerous fast-moving type of landslide that scientists call
“debris flow.” Known less formally as mudslides, these flows
are typically triggered by short, intense storms and can send
tides of soil, ash, vegetation, rocks and even cars and homes
careening downhill, destroying everything in their path.
Most states are doing a mediocre job – and some even a poor one
– of managing shorelines and preparing for sea-level rise,
according to a new study by the Surfrider Foundation.
California, on the other hand, is a “shining example” and has
excelled in responding to changes along the coast, earning the
only “A” grade in the nation — but the report found there are
still areas that need improvement…
The Del Puerto Water District is set to vote Wednesday on
approving a final environmental impact study on a much-disputed
storage reservoir in western Stanislaus County. … According
to proponents, the reservoir storing up to 82,000 acre-feet
will provide more reliable water deliveries to farmers south of
the Sacramento-San Joaquin Delta… Water pumped from the
nearby Delta-Mendota Canal would be stored behind the dam.
Working over the last year, construction crews expect to
complete a new 2-mile levee near Novato in the coming weeks. It
will allow bay waters to eventually reclaim nearly 1,600 acres,
or about 2.5 square miles, of former tidal marshes that had
been diked and drained for agriculture and development during
the late 19th and early 20th centuries.
Now in its second year, a long-term project intends to learn
whether rice farming in the Sacramento-San Joaquin Delta can
succeed economically while helping to preserve the region’s
uniquely carbon-rich peat soils.
Experts say it’s likely not a matter of if, but when, intense
rainfall triggers mudslides that threaten the properties and
lives of thousands of people in the Santa Cruz Mountains. The
area has seen these disasters before: In January 1982, the Love
Creek mudslide killed 10 people near Ben Lomond. But the CZU
Lightning Complex, larger than any fire in the region’s
recorded history, created an unprecedented hazard.

Protecting intact peatlands [such as those in California] and
restoring degraded ones are crucial steps if the world is to
counter climate change, European researchers said Friday. In a
study, they said peat bogs, wetlands that contain large amounts

over centuries, could help the world achieve climate goals like
the limit of 2 degrees Celsius of postindustrial warming that
is part of the 2015 Paris agreement.

2014’s King fire.
Californians are understandably focused on the wildfires that
have charred more than 3 million acres and darkened our skies –

When fires burn up vegetation, the charred remains become
hydrophobic—meaning they repel away any water. The soil is also
very dry, which counterintuitively makes it harder for water to
infiltrate. … Fires can also destroy the natural clumps in
soil, increasing their erodibility. Altogether, this means that
water is hitting the ground with more force and the soil is
unable to suck it up.
For years, a stretch of Chorro Creek near Hollister Peak ran
through active farmland, where its flow was diverted for
irrigation and its banks were shored up by levees, blocking the
water’s natural access to its floodplain. … After nearly two
decades of planning and fundraising, the Estuary Program and
its partners recently completed a major restoration of the
New mapping of salt concentrations in the world’s oceans
confirms what physics and climate models have long suggested:
Global warming is intensifying Earth’s water cycle, speeding up
the rate at which water evaporates in one area and falls as
rain or snow somewhere else. That intensification has enormous
implications because it worsens droughts and increases extreme
rainstorms and flooding.
Zone 7 Water Agency’s failed flood control system needs a total
revamp from the ground up, according to a consultant hired by
the agency. The system can’t be saved by adding touches here

At the August meeting of the Delta Independent Science Board,
the new members joined with the outgoing members for
reflections and discussion to bring the new members up to speed
on the Delta ISB’s ongoing work.
The idea was to lower the flows while temperatures were still
warm enough to dry out the caddis larvae. That required buy-in
from local merchants and the Bureau of Reclamation, local
tribes and others. They were able to do it, and on Aug. 27, the
first of two flow reductions took place. When the river
dropped, people pitched in for a day of river cleanup.
The San Francisco Bay-Delta is literally threatened from all
sides: rising sea levels from the ocean, disruptions to
sediment supply from upstream, and within the Bay-Delta itself,
development and other land use changes have left only a tiny

forced to bear.
People hoping to get a handle on future droughts in the
American West are in for a disappointment, as new University of
Southern California-led research shows El Niño cycles are an
