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.
Remember the parade of atmospheric-river storms that deluged
the Bay Area last winter, giving us the wettest rainy season in
20 years? There are a lot more of those on the way, scientists
say. But California will also experience more periods of
extreme dryness, according to a new study led by Scripps
Institution of Oceanography at UC San Diego.
The Department of Water Resources released the final guidelines
for the Riverine Stewardship Program on July 1, 2019. The grant
program supports planning and implementation of projects that
restore streams, creeks, and rivers to enhance the environment
for fish, wildlife, and people.
A massive flow of fresh water is being released from Friant Dam
on Tuesday as Millerton Lake reached capacity. … Officials
are releasing 1,700-1,000 cubic feet per second into the San
Joaquin River. Stroup said Millerton Lake has received above
average snow melt forcing them to release the water to make
room for more run off.
Santa Clara Valley Water District (Valley Water) has resumed
pre-construction activities in Alviso, California, delivering
on a long-made promise to protect shoreline communities in
Santa Clara County from devastating flooding.
It is a telling illustration of the precarious state of United
States dams that the near-collapse in February 2017 of Oroville
Dam, the nation’s tallest, occurred in California, considered
one of the nation’s leading states in dam safety management.
The original treaty was implemented before the 1970 National
Environmental Policy Act, the 1973 Endangered Species Act and a
host of legal shifts that bolstered Indigenous rights… These
hallmarks of change emphasize the need to include environmental
protection and equity in an updated treaty.
In 2016 California’s rainy season kicked off right on schedule,
at the beginning of October. … By February there was so much
water filling Northern California’s rivers that Oroville Dam,
the tallest in the country, threatened to break after its
spillway and emergency spillways both failed. It was a wake-up
call. In just a few months California had gone from
five-year-drought to deluge, ending up with the second wettest
year on record for the state.
Wildfire and drought dominate the climate change debates in the
state. Yet this less-talked-about reality has California
cornered. The coastline is eroding with every tide and storm,
but everything built before we knew better — Pacific Coast
Highway, multimillion-dollar homes in Malibu, the rail line to
San Diego — is fixed in place with nowhere to go.
We need a broad portfolio of solutions that includes storage
above and below ground, conservation, and other options such as
traditional recycled and potable reuse to help ensure we can
better manage this vital resource when the next inevitable
drought comes along. … One part of that solution is the
proposed Sites Reservoir.

A new bill is moving through the California Legislature that
may make it easier for veterans to get jobs within the state’s
water industry. Assemblymember Todd Gloria helped introduce AB
1588 to stem the phenomenon called the “silver tsunami”, in
which thousands of water workers are expected to retire from
the water industry in the coming years.
Rising sea levels caused by climate change are prompting the
city of Monterey to prepare for a worst-case scenario, which

The Obama administration violated the law when it issued its
embattled definition of “waters of the United States,” a
federal court ruled yesterday. In a long-awaited decision, the
U.S. District Court for the Southern District of Texas sided
with three states and a coalition of agriculture and industry
groups that have been trying to take down the joint EPA and
Army Corps of Engineers rule since 2015.
Before the threat of rising seas was widely understood,
California created an agency to protect its famous beaches from
overdevelopment. Now the state Coastal Commission is pouring
resources into a war against the effects of climate change, and
it could lead toward the removal of oceanfront homes.
Hermosa Beach, partnering with neighboring cities, was supposed
to receive the money from the State Water Resources Control
Board to help design and build the Greenbelt Infiltration
Project … meant to help clean the Herondo Drain Watershed,
which has consistently had elevated levels of bacteria. But the
city put the funding in jeopardy in March when the council
voted to dissolve a deal with neighboring cities and instead
find a new home for the project.
In order to address the impacts of climate change on the
state’s water resources, the Department of Water Resources

Although flooding hasn’t occurred in Clarksburg since the
construction of the levee system in the early 1900s, the
community is considered a moderate to high hazard flood area,
according to a county report. For that reason, a flood risk
reduction feasibility study has been prepared for the town
similar to those conducted for Yolo and Knights Landing with
funds from the California Department of Water Resources.
Slurries of mud increasingly threaten the water we drink. This
rush of sediment, known as “debris flow,” is a type of erosion
where mud and boulders in steep catchments suddenly tumble down
the stream channel, often traveling at speeds of several meters
per second. … Last year, California saw mudslides that
destroyed more than 100 homes and killed 21 people.
Del Puerto Water District and Central California Irrigation
District have developed the reservoir project without many
public concerns rising to the surface. That was until Patterson
city staff members showed up for Wednesday’s meeting. Maria
Encinas, a city management analyst, asked about a risk
assessment for adjacent communities like Patterson. A failure
in the dam on Del Puerto Creek, on the west side of Interstate
5, would appear to flood part of the city of 23,700, including
perhaps the downtown area in Patterson.
It took two consulting groups, but a project charter for the
Sierra Valley Flood Hazard Restudy Project is finished and now

Governor Newsom recently called for a state portfolio of
actions to manage water under rapidly changing climate and
other conditions. This post reviews the state of water
portfolio planning in California today.
In retrospect, it’s clear: We’ve misunderstood how rivers work.
They don’t follow wishful parameters of the Army Corps of
Engineers’ 100-year flood guidelines, or the routes we’ve
penciled in between levees, or even the climatic expectations
of the past. A national program that presumes we can
choreograph today the floods of tomorrow is fundamentally
flawed. It’s time to recognize that the rivers will have their
way. Therefore we need to get out of the way.
A beach closure that has been in place for months for the
southern part of the Imperial Beach was extended Sunday to
include the city’s entire shoreline. The San Diego County
Department of Environment Health issued the order to close the
coastline to swimmers as a result of sewage-contaminated runoff
in the Tijuana River.
A facility designed to increase water supply reliability for
the Inland area was dedicated in a light rain at the foot of
the hulking Seven Oaks Dam near Highland on Thursday, May 23.
Officials used a new concrete diversion box to move water
rushing from the dam to a new sedimentation basin and beyond.
The water is intended to spread out and seep into a groundwater
basin, which officials have said is historically low due to a
An investigation into the Bay Conservation and Development
Commission found mismanagement and disorganization so rampant
that the once-celebrated watchdog agency allegedly neglected
its primary responsibility — to protect San Francisco Bay. A
state audit of the regulatory agency known as the BCDC
describes slow and inefficient enforcement, a huge backlog of
cases and an inability to perform key duties.
There are more concerns over lake levels in Oroville as Butte
County leaders take initiative to explore alternative options
for safety measures. The Department of Water Resources (DWR), a
leg of the State Water Project, manages the Oroville Dam. On
Wednesday, DWR officials remained adamant in saying they have
no plans to release water from the Oroville Dam spillway.
Called the Monterey Bay Opportunistic Beach Nourishment
Program, the plan entails hauling beach-quality sand from other
inland locations as a result of construction, development or
dredging projects. The sand would be added to stockpiles at
different locations and then be applied to dry sand areas above
high tide marks…
The idea is simple, the task gargantuan: Remove 1.7 million
cubic yards of sediment to return the circa 1920 dam to full
functionality, protecting Pasadena, South Pasadena, Highland
Park and other northeast Los Angeles communities downstream —
including the Rose Bowl, Brookside Park and the Arroyo Seco
Parkway — from the potential flooding of a 100-year storm.
Legislation that would require the state to enhance its river
and stream gauging system has cleared the state Senate. … The
bill requires the Department of Water Resources and Water
Control Board to improve and enhance the monitoring system,
including filling those gaps that are found, as well as assess
a funding source to complete the work.
While Belvedere officials consider a series of flood control
projects that could cost up to $27.1 million, the city has
appointed a new advisory committee that represents some of the

The combination of droughts and floods has given rise to a
process known as saltwater intrusion — what San Jose Mayor Sam
Liccardo refers to as his city’s greatest climate threat. …
In coastal regions like San Jose, overpumping allows seawater
to seep into the city’s aquifers, exposing local residents to
excess sodium in their drinking water. The problem is
compounded by sea level rise, which pushes seawater inland
toward the city’s filtration system.
Residents whose homes were flooded will not be eligible for
financial aid from the Federal Emergency Management Agency
because state officials determined the amount of damage was
insufficient to qualify.
Two days of above-average spring rainfall in the North Bay have
forced Sonoma County officials to begin deflating the seasonal
dam across the Russian River, an about-face that comes less
than a week after the rubber dam was fully inflated to serve
the region’s drinking water system.
President Trump signed a disaster declaration Saturday for 17
Northern California counties that endured battering rains and
landslides this year, making them eligible for federal relief.
The move followed three emergency proclamations this year by
Gov. Gavin Newsom, who directed Caltrans to seek federal
assistance for a string of brutal February storms that doused
rural areas across the state, damaging roads and bridges.
The funding allows CalTrout to develop a broad team of agency
partners to restore a 950-acre tidal marsh estuary surrounding

A federal judge in San Francisco ruled Wednesday to block the
Federal Emergency Management Agency from moving forward with
its plans to offer flood insurance to developers and property
owners in 100-year flood zones in California, finding that the
agency failed to consider effects development might have on
endangered wildlife in those areas.
The commission, created in 1965 and comprised of 27 members
appointed primarily by state and local officials, is supposed
to protect the environmental health of the bay. If they won’t
take their job seriously, Gov. Gavin Newsom, legislative
leaders and local officials should replace them with people up
to the task.
The Mountain View City Council approved the water district’s
18-foot-deep basin project in 2013 in exchange for the park
upgrades. Designed to accommodate a 100-year flood, the
McKelvey Park basin is one of two basin projects of the larger
Permanente Creek Flood Protection Project, which water district
officials claim will provide natural flood protection for
approximately 2,200 properties in Mountain View and Los Altos.
Federal engineers are raising alarms that a “significant flood
event” could breach the spillway of Southern California’s aging
Prado Dam and potentially inundate dozens of Orange County
communities from Disneyland to Newport Beach. After conducting
an assessment of the 78-year-old structure earlier this month,
the U.S. Army Corps of Engineers announced that it was raising
the dam’s risk category from “moderate” to “high urgency.”
The San Francisco Bay Conservation and Development Commission
has “neglected its mission” to protect the bay and surrounding
wetlands, the California state auditor reported Tuesday. The

Estimates vary, and can change as the water year progresses,
but the Kern River basin, the rivers and streams that collect
the water that flows into Isabella Lake and downstream toward
Bakersfield, is estimated to be at 172 percent of normal,
possibly more. And all that ice and snow is starting to melt,
big time. Are local water managers ready?
People who live along the southern border all say the same
thing: When it rains, it stinks. The reason is a failing, aging
network of pipes that run from Mexico to wastewater treatment
plants in the U.S. When heavy rains fall, the pipes often break
and spill raw sewage on both sides of the border, causing not
only a putrid odor but public health and environmental
Rivers may seem especially appealing as the weather becomes
warmer in the spring and summer, but experts and local
officials warn that the waters may not be as welcoming as they
seem. The snowpack that accumulated during a wet and cold
winter is beginning to melt into rivers, making for extremely
cold water and fast currents. “It’s a very dangerous
combination,” said Chris Orrock, a spokesman for the state’s
Department of Water Resources.
After sunshine and pleasant weather grace California early this

coastal California will receive between 1 to 3 inches of rain.
The hardest-hit locations may receive as much as 4 or 5 inches
When people think of natural disasters in California, they
usually think of earthquakes, drought or wildfire. But the
worst disaster to ever hit the Golden State was the Great Flood
of 1862. When people of European descent first arrived in
California, the native people told them tales of great deluges
in which the rivers overran their banks and large areas of land
were inundated. The newcomers paid little heed to these
stories, and often settled in low-lying areas with easy access
to water sources.
There’s three roads that go up to the hill. Because of flooding
and mudslides, all three of them were blocked. So here we were,
an island. There was no way to get supplies. No way to get
medication. No way to get propane deliveries for heat. People
who work on and off the hill couldn’t go to their jobs. The
whole town was impacted, especially the businesses and
restaurants who depend on the tourism.

Reforestation will improve watershed conditions by restoring
severely burned areas to forested conditions, reducing
sedimentation and turbidity, and improving water quality for
downstream users. It will also improve habitat by providing
stabilization that reduces erosion of stream banks and meadows.
Sometimes erosion can be caused by fallen trees or rodents, but
now they’re finding faults intentionally caused by homeless
people carving out campsites. … Tim Kerr, general manager for

There are actions we can take today that will reduce the
pressure on struggling sea life and protect the industries and
communities that rely on a healthy ocean. … The Ocean
Resiliency Act of 2019 (Senate Bill 69) tackles a range of
threats facing our fisheries, from fertilizer runoff that feeds
harmful algae to sediment flowing downstream from logging
operations that violate clean water rules, which can silt up
the spaces between rocks where baby salmon shelter and feed.
A new category of El Niño has become far more prevalent in the
last few decades than at any time in the past four centuries.
Over the same period, traditional El Niño events have become
more intense. This new finding will arguably alter our
understanding of the El Niño phenomenon. Changes to El Niño
will influence patterns of precipitation and temperature
extremes in Australia, Southeast Asia and the Americas.
Only 37 percent of the world’s longest rivers remain unimpeded

In April 2019, the California State Water Resources Control
Board unanimously approved a comprehensive new legal framework
for protecting California’s wetlands. California has lost
approximately 90% of its historic wetland areas, which have
important water quality, species habitat and other
environmental and economic benefits. … California has never

Before California’s Central Valley became known as an
agricultural powerhouse, it contained one of the largest
expanses of streamside forest and wetland habitat in North
America. … Much of that landscape has been transformed into
farmland and urban areas, but at the Cosumnes River Preserve, a
unique partnership of nonprofits and state, federal and local
governments has conserved over 50,000 acres that provide
resources for a variety of wildlife.
Implementation of the Sustainable Groundwater Management Act
(SGMA) was always going to be tricky. Part of the necessary
growing pains of SGMA is determining how the revolutionary
statute interacts with traditional tenets of water law. As with
any other sweeping legislative change, SGMA does not provide
direct answers for every practical question which arises as the
law is put into place.
Snowpack in every part of Colorado’s high country is sporting
layers of dust, according to a new statewide survey of the
state’s winter accumulation. … Dust is darker than snow. Just
like a black T-shirt on a sunny day, it absorbs more sunlight,
causing what’s underneath it to heat up more rapidly.
We’ve made it through most of the prime water season and have
had a few blockbuster winter storms. For many large reservoirs
in California the mission for reservoirs switches from flood
control to water storage and there isn’t much room left for
storage. All major Northern California Reservoirs are more than
90 percent full and many will reach capacity in a month or so.
Across its multitude of neighborhoods, communities and
cultures, the City of Long Beach offers a diverse haven for

An ambitious California irrigation drainage deal is now mired
deeper than ever in legislative and legal limbo, alarming
farmers, spinning government wheels and costing taxpayers money
with no relief in sight. Though nearly four years have passed
since the Obama administration and the Westlands Water District

measured in inches.
There’s only one San Francisco Bay. But the Bay Area is made up
of nine counties and 101 cities, each with its own politics,
local rules and shorelines, differences that can make it

As California’s Central Valley grew into the nation’s leading
agricultural corridor, the region gradually lost almost all of
the wetlands that birds depend on during their migrations along
the West Coast. But a dramatic turnaround is underway in the
valley. Dozens of farmers leave water on their fields for a few
extra weeks each season to create rest stops for birds. The
campaign has not only helped salvage a vital stretch of the
north-south migration path called the Pacific Flyway but also
tested a fresh model for protecting wildlife.
The city of Escondido thought it had finally figured out how to

In 2017, a swarm of seismic activity occurred near California’s
Long Valley Caldera in the Mammoth Mountain area. During the
same period of seismic activity, the area had high levels of
flooding due to snowmelt. The 2016-2017 winter brought heavy
snow that created one of the largest snowpacks ever recorded in
California’s history. A record amount of snowfall occurred in
the same region this year, raising the question of whether the
same occurrence will happen in 2019.
This research will supply information needed for the U.S. Army
Corps of Engineers to update the 1970’s-era water control

manual approved about the same time the agency completes
construction of a new, planned secondary spillway at its New
Bullards Bar Dam, estimated for completion in 2024.

An automated gate was supposed to open once water levels got
high enough to overflow into the bypass, allowing fish to swim
back into the Sacramento River. But in February … too much
water was pouring through the passage, eroding the structure.
Officials had to close the gate almost entirely, meaning fewer
fish could escape. The Department of Water Resources is now
facing an expensive upgrade to an already multimillion
structure to make it ready for the next rainy season.
The San Rafael Canal needs dredging — again. That’s no
surprise. The waterway into Central San Rafael regularly
becomes clogged with silt and has to be dredged to assure
free-flowing boat traffic. But it’s also no surprise that
maintenance dredging of the canal is going to require a
mustering of political lobbying to get the U.S. Army Corps of
Engineers to include the job in its budget.

The February storms that swelled the Russian River to its
highest level in more than two decades did $23 million in
damage to Sonoma County roads, including more than 100
landslides and slipouts, leaving county crews and contractors
with a Herculean repair job that will take months to complete.
The Sierra Club and other conservationists have expressed
worries that without CEQA’s strict protections, next winter’s
first rains could result in mud flows into drinking water
supplies, or the disturbance of the range of an endangered or

will create air pollution that will impact people in
By the 1930s, the Leslie Salt Company had consolidated over a
dozen small producers into the world’s largest industrial salt
production company, and half of the South Bay’s extensive
marshes, whose ducks and salmon once far outnumbered humans,
were gone. Now, the south San Francisco bay shoreline’s next
mammoth transformation is well underway: a 50-year project to
return the salt ponds back to the bay, restoring them once
again into tidal marsh for the first time in 150 years.
For centuries, the Delta was a dynamic and rich ecosystem of
tidal wetlands, riparian forests, and vast seasonal
floodplains. But about 98 percent of the native habitat
disappeared after the Gold Rush and a population boom across
the Golden State.
Ten-acre Albion Riverside Park can get a lot done. The green
infrastructure built into the park can clean the stormwater

groundwater basins. The price tag on the park is about $40
million. The new park sits on the old Downey Recreational
Center and the Swiss Dairy site, bringing new athletic fields
and more to the community.
Napa County is still trying to open the door for federal money

readings (updated from a 2012 post) on California water.
Introduced by State Senator Scott Wiener (D-SF) and backed by a
diverse array of environmental and business interests, SB 69,
“The Ocean Resiliency Act,” tackles questions as big as the
ocean itself. How much waste does California put in the ocean?
How much more can our oceans take? And how will climate change
amplify our mistreatment of our natural resources?
Local river protection groups and a state regulatory board are

The National Flood Insurance Program provides coverage to more
than 5 million households and small businesses across the
United States, including more than 229,000 in California. The
program has been hard hit by payouts from major flood disasters
in recent years and is heavily in debt. The Federal Emergency
Management Agency (FEMA), which houses the program, has
recently announced significant changes. We talked to Carolyn
Kousky, a flood insurance expert at the Wharton Risk Center at
the University of Pennsylvania … about the program.
Frustration was evident, whether it was from a flooded
homeowner or a government agency trying to explain its
processes during Wednesday’s “listening session” regarding
flooding in north Chico. … Despite the anger, there seemed to
be some progress, whether it was the cleaning of Rock Creek
west of Highway 99 by the Rock Creek Reclamation District, or
more property owners funding efforts themselves. Lucero
suggested that property owners could pay more into the existing

Residents in north Chico say they have never seen flooding like
the deluge that came their way this year, and they want to know
how to stop it. Storm water from Rock Creek and Keefer Slough
surged into their backyards, front yards, and in some cases
into their homes. It crept into orchards and overtook Highway

It’s not clear how much water this year’s snowpack will
produce, but the record snowpack in 2017 produced about one
million acre feet of water. That’s too much for a funnel only
about one-third that size. That means that water managers have
to figure out where to put the excess water as it melts off the
mountains. And the problem becomes potentially worse if a warm
streak hits and melts the snow fast
All this reliance on an overallocated river has left its final

In California, the amount of water exiting aquifers under the
state’s most productive farming region far surpasses the amount
of water trickling back in. That rampant overdraft has caused
land across much of the region to sink like a squeezed out

For the millions of Californians who live and work far from the
Delta, it can be easy to overlook the splendor of the largest
estuary in western North America. Whether you are one mile or
hundreds of miles from the Delta, however, all Californians
have a stake in the survival and preservation of this fragile,
dynamic ecosystem that is also the keystone of the state’s
water supply system.
Among other ramifications, the new procedures largely duplicate

California received some good news on Tuesday for the state’s
water supply: The Sierra Nevada snowpack is well above normal,
at 162 percent of average. This amount of snow is thanks to the
more than 30 “atmospheric rivers” that brought storms this
winter and spring. Chris Orrock, with the California Department
of Water Resources, says … this is the fourth largest amount
of snow in recorded history.
It worked. Oroville Dam’s main flood-control spillway reopened
for business Tuesday morning, releasing a gentle sheet of water
into the Feather River for the first time since the 2017 crisis
that sent 188,000 people fleeing for their lives. … It was a
far cry from the scene two years ago, when the massive sinkhole
in the spillway turned water releases into an angry, boiling

Alongside auto wrecking yards and shipping centers off state
Route 905, a pop-up world has emerged with some of the
strangest creatures to swim in six inches of water. Here
aquatic plants grow next to cacti, and animals that have waited
for decades in the dust come to life. In this Otay Mesa
preserve are some of San Diego’s vernal pools, fleeting water
bodies that appear and vanish over the course of a season.
Officials predict they might need to open the gates to move
water that accumulated during the wet winter season from the
reservoir down into the Feather River. … Amy Rechenmacher, an
associate professor of engineering practice at USC, said the
spillway’s use is going to be a big test for the agency and

Fortunately, California has developed a forward-looking Central
Valley Flood Protection Plan to meet this challenge. In his
first state of the state address, Gov. Gavin Newsom highlighted
the central tenet of the flood plan—investing in floodplain
improvements that give rivers more room to safely bypass flood
waters around cities and infrastructure.
If it seems that wildfires are burning nearly all the time
these days, that there’s no longer a definable fire season in
California, you’re right. Fourteen of the 20 most destructive
fires in state history have occurred since 2007, and California
has 78 more annual “fire days” now than it had 50 years ago.
It’s been a big year for snow in the Sierra Nevada range. This
is the time of year—April 1—when the snowpack is typically at
its peak and on Tuesday, when surveyors do their monthly manual

of the average.
Hermosa Beach City Council has scrapped a large stormwater
infiltration project slated for the southern end of city’s
greenbelt, after more than a year of opposition from residents.
City officials will look for a new home for the project, meant

could potentially forfeit nearly $3.1 million in grant funding
from the State Water Resources Board.
Lawmakers are considering spending $150 million to fund new
high-tech measurements of the snowpack using lasers. … The
new hi-tech approach is meant to help water managers know
exactly how much water they can expect in water runoff from the
snowpack – and when that runoff will arrive in reservoirs,
rivers, and streams.
For the past year the state’s worked to eradicate the rodents
for a second time. The rodents were brought to California in
the 1900s for the fur trade and fur farming. “[The] challenge
is we keep looking and we keep finding more nutria,” said Peter
Tira with the California Department of Fish and Wildlife.
“However, we do know there’s about 1.8 million acres of
suitable nutria habitat. This is the largest nutria eradication
ever attempted in the United States.”
