Oroville Dam is the centerpiece and largest water storage
facility of the State Water Project. Located about 70 miles north
of Sacramento at the Feather River confluence, Oroville Dam
creates a reservoir that can hold 3.5 million acre-feet of water.
Features such as a fish barrier dam and pool at Oroville Dam made
the SWP one of the first major water projects built with
environmental protections as a major consideration.
Besides storing water, the dam also protects downstream residents
from the floodprone Feather River—the main feeder of the SWP— and
provides major water recreation facilities such as boating,
fishing and camping.
California is in the second year of a drought. Governor Newsom
this week made his first drought declaration. Just how dry is
this drought, so far? What are some likely
implications? And what might State and local governments
do about it?
The Yuba Water Agency manages water storage and deliveries to
downstream customers while having a hand in preserving fish
habitats and recreational areas. Currently, the agency has
already begun doubling its reservoir releases at a time when
visitors to the river are also expected to go up. Due to
the time of year, those releases from upstream reservoirs are
dictated by irrigation needs of downstream growers.
On Wednesday, March 3rd, the Northern California Water
Association (NCWA) Board of Directors officially adopted our
2021 Priorities. The water leaders in this region look forward
to working with our many partners in 2021 to cultivate a shared
vision for a vibrant way of life in the Sacramento River Basin.
We will continue to re-imagine our water system in the
Sacramento River Basin as we also work to harmonize our water
priorities with state, federal, and other regions’ priorities
to advance our collective goal of ensuring greater water and
climate resilience throughout California for our communities,
the economy, and the environment.

U.S. Agriculture Secretary Tom Vilsack designated 50 California
counties as natural disaster areas last month because of the
drought. And, over the weekend, Fresno Congressman Jim Costa
said on KSEE-24’s Sunday Morning Matters program that Gov.

California’s hottest commodity could become even more scarce as
state and federal officials announce water cutbacks on the
brink of another drought. Now, state legislators are banding
together to ask Governor Newsom to declare a state of emergency
amid what they call a water crisis. … [State Senator Andreas]
Borgeas authored a letter alongside the Assembly agriculture
committee chair and several other state lawmakers to send to

growers in late March.
San Francisco Bay’s life support systems are unravelling
quickly, and a wealth of science indicates that unsustainable
water diversions are driving this estuary’s demise. Yet,
with another drought looming, federal and state water managers
still plan to divert large amounts of water to their
contractors and drain upstream reservoirs this summer.
Meanwhile, the state’s most powerful water districts are
preparing yet another proposal to maintain excessive water
diversions for the long-term. By delaying reforms that the
law requires and that science indicates are necessary, Gov.
Gavin Newsom encourages wasteful water practices that
jeopardize the Bay and make the state’s water future
precarious. -Written by Jon Rosenfield, a senior scientist for SF
Updated water supply allocations announced last week would
still drain upstream reservoirs in order to deliver 4.5 million
acre feet of water to the contractors of the federal Central
Valley Project (CVP) and State Water Project (SWP), devastating
fish and wildlife. This week, the fisheries biologists at the
National Marine Fisheries Service projected that these planned
operations are likely to result in lethal water temperatures
that will kill 89% of endangered winter-run Chinook salmon
below Shasta Dam this year. This mortality estimate is even
worse than what was observed in 2014 and 2015, when salmon
populations were devastated by warm water in their spawning
State and federal water officials have delivered their most
dire warning yet of California’s deepening drought, announcing
that water supply shortages are imminent and calling for quick
conservation. Among a handful of drastic actions this week, the
powerful State Water Board on Monday began sending notices to
California’s 40,000 water users, from small farms to big cities
like San Francisco, telling them to brace for cuts. It’s a
preliminary step before the possibility of ordering their water
draws to stop entirely.
If you were around here in 2014 or 2015, you were likely
inundated with images of dried up reservoirs that looked like
dirt canyons with little ponds in them, when a punishing
drought forced the state to institute restrictions on water
usage. Well, we’re likely headed for another summer of dried-up
lawns (and wildfires) if Mother Nature continues to withhold
the rain and snow that we need to make up for a super-dry
November, December, and February.
We’re facing another very dry year, which follows one of the
driest on record for Northern California and one of the hottest
on record statewide. The 2012-16 drought caused
unprecedented stress to California’s ecosystems and pushed many
native species to the brink of extinction, disrupting water
management throughout the state. Are we ready to manage
our freshwater ecosystems through another drought? -Written by Jeffrey Mount, senior fellow,
and Caitrin Chappelle, associate director, at
the Public Policy Institute of California Water Policy
As March begins to drag on with little precipitation in the
forecast and few weeks left in California’s traditional wet
season, we are in another dry year. This is California’s second
dry year in a row since the 2012-2016 drought.
Statistically, California has the most drought and flood years
per average year than anywhere in the US. This
statistical fact seems to becoming increasingly extreme, as
predicted by many climate change models.
Dwindling Chinook salmon runs have forced the Pacific Fishery
Management Council to shorten the commercial salmon fishing

higher than the 2020 but is still significantly lower than the
long-term average. During a press briefing on Friday morning,

On the tail end of the second dry winter in a row, with water
almost certain to be in short supply this summer, California
water officials are apparently planning to largely drain the
equivalent of the state’s two largest reservoirs to satisfy the
thirst of water-wasting farmers. Gov. Gavin Newsom must stop
this irresponsible plan, which threatens the environmental
health of the Sacramento-San Joaquin Delta and the water supply
for about one-third of the Bay Area residents. We should be
saving water, not wasting it.
Water levels in the world’s ponds, lakes and human-managed
reservoirs rise and fall from season to season. But until now,
it has been difficult to parse out exactly how much of that
variation is caused by humans as opposed to natural cycles.
Analysis of new satellite data published March 3 in Nature
shows fully 57 percent of the seasonal variability in Earth’s
surface water storage now occurs in dammed reservoirs and other
water bodies managed by people. … The western United
States, southern Africa and the Middle East rank among regions
with the highest reservoir variability, averaging 6.5 feet to
The American Society of Civil Engineers (ASCE) gave America’s
infrastructure a C- grade in its quadrennial assessment issued
March 3. ASCE gave the nation’s flood control infrastructure –
dams and levees – a D grade. This is a highly concerning
assessment, given that climate change is increasingly stressing
dams and levees as increased evaporation from the oceans drives
heavier precipitation events. … Climate scientists at
Stanford University found that between 1988 and 2017, heavier
precipitation accounted for more than one-third of the $200
billion in [flood] damage…
California will face another critically dry year, and residents
will need to adapt quickly to cope with water shortages and a
warmer, drier climate that has helped fuel destructive
wildfires. Officials with the state’s department of water
resources announced on Tuesday they had found that the water
content of the overall snowpack for 2 March amounted to 61% of
the average. The state’s largest reservoirs were storing
between 38% and 68% of their capacity, officials said, meaning
that the state would have a lot less water to carry it through
the rest of the year.
The winter storms that dumped heavy snow and rain
across California early in 2021 are likely not enough to negate
what will be a critically dry year, state water officials
believe. California’s Department of Water Resources on
Tuesday recorded a snow depth of 56 inches and water content of
21 inches at Phillips Station in the Sierra Nevada. The water
content of the overall snowpack was 61% of the average for
March 2 and 54% of the average for April 1, when it is
historically at its maximum.
The Bureau of Reclamation and Department of Water Resources
plan to allocate approximately 5 million acre feet of water
this year – as long as California allows them to effectively
drain the two largest reservoirs in the state, potentially
killing most or nearly all the endangered winter-run Chinook
salmon this year, threatening the state’s resilience to
continued dry conditions, and maybe even violating water
quality standards in the Delta.
The process to recoup over $1 billion in repairs to Oroville
Dam’s spillways after the 2017 crisis is receiving more federal
funds. The Department of Water Resources announced Feb. 1 that

approximately $308 million in requested funds for the Oroville
Dam spillways reconstruction and emergency response. These
funds are in addition to over $260 million that FEMA has
already committed to …
Although the 1971 San Fernando earthquake and the near failure
of the Lower Van Norman Dam have given rise to construction
improvements … the overwhelming majority of California dams
are decades past their design life span. And while earthquakes
still loom as the greatest threat to California’s massive
collection of dams, experts warn that these aging structures
will be challenged further by a new and emerging hazard:
“whiplashing shifts” in extreme weather due to climate change.
California Water Service (Cal Water) has announced temporary
leadership changes for its Oroville District. Evan Markey has

Tens of thousands of large dams across the globe are reaching
the end of their expected lifespans, leading to a dramatic rise
in failures and collapses, a new UN study finds. These
deteriorating structures pose a serious threat to hundreds of
millions of people living downstream…. In 2017, a
spillway collapsed at the 50-year-old Oroville Dam in
California’s Sierra Nevada foothills. It caused the evacuation
of around 180,000 people. The 770-foot dam is the highest in
the U.S. and, after repairs to the spillway, remains critical
to the state’s water supply.
The California Department of Water Resources has secured $308
million in funding to pay for reconstruction and repair work
that has been done on the Oroville Dam’s spillways. The funds,
released by FEMA, are in addition to the $260 million that the
agency provided for repairs on the lower portion of the dam’s
main spillway. Repair work on the damaged emergency and main
spillways has been ongoing for nearly four years following
February 2017’s spillway crisis. The $308 million announced
Monday was at first rejected but later approved by FEMA
following an appeal from the DWR last year.

The Department of Water Resources recently published a summary
report of a comprehensive needs assessment of safety at
Oroville Dam. It comes after the reconstruction of the
spillways that were damaged and failed in 2017.
A 19-month study of the safety of the Oroville Dam project has
found no “unacceptable risks.” The Department of Water
Resources released its Comprehensive Needs Assessment on Oct.
30, and notes its findings generally agree with those of an
Independent Review Board and a regular five-year review by the
Federal Energy Regulatory Commission…
A team of experts released their findings Monday, concluding
that no urgent repairs are needed right now on the Oroville
Dam. The report goes on to say that the largest earthen dam in
America is safe to operate. However, the Oroville Dam is not
completely in the clear.
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.
The North Complex Fire has burned a large portion of Lake

In February 2017, damage to the Oroville Dam’s spillways
prompted the evacuation of more than 180,000 people living
downstream along the Feather River. The raging muddy waters
also triggered an emergency decision to relocate millions of
young salmon from the Feather River Hatchery to the Thermalito
Annex Hatchery to be raised and held until river water
conditions improved. … Those fish survived and were later
released to the wild – helping fuel a record class salmon
harvest in the ocean two years later.

The California Department of Water Resources announced an
initial State Water Project allocation of 10% for the 2020
calendar year. According to a DWR announcement, the initial
allocation is based on several factors, such as conservative
dry hydrology, reservoir storage, and releases necessary to
meet water supply and environmental demands.
There were questions about the gates that release the water
from Lake Oroville, even before the spillways broke up in
February 2017. Those questions never really got answered. The
focus was on fixing the obvious damage. We could get around to
talking about the gates after that. Maybe.
Despite increased maintenance of Oroville Dam since the
spillway fell apart in February 2017, members of the
community-led Oroville Dam Ad Hoc Group have expressed concern
about the age and wear of mechanics within the spillway’s main
gates, citing similar failures on dams of the same era.

The state Department of Water Resources and Butte County

This past December, DWR reconnected electricity to the Ronald
B. Robie Thermalito Pumping-Generating Plant in Oroville, a
major step towards returning the plant to full operation. A
fire in November 2012 destroyed the plant’s operating capacity,
requiring closure of the facility and its disconnection from
the state’s electrical grid. …
Lake Oroville, currently at 773-foot elevation, could rise to
780-785 feet by the end of the month based on current
projections. DWR and crews with Kiewit Infrastructure West Co.,
the contractor for the spillways construction project, would
remove equipment from the main spillway if the lake elevation
reached 780 feet.
Major dams in California are five times more likely to flood
this century than the last one due to global warming, a new
study finds, possibly leading to overtopping and catastrophic
failures that threaten costly repairs and evacuations. That
means Californians can expect more disasters like the Oroville
Dam, whose overflow channel failed in 2017 after days of
flooding had filled state reservoirs to 85% of their capacity.
Lawyers representing the state Department of Water Resources
will make their case Friday for striking portions of lawsuits

Water Resources, alleges he saw something he would never
forget. A legally deaf woman was assigned to drive a truck
down the spillway and listen for hollow sounds in the concrete
as her colleagues performed what’s known as “chain drag
testing,” Hopkins wrote in a declaration filed last week in
Sacramento Superior Court.
Several areas of the Oroville Dam and lake are undergoing
extensive renovations and improvements, and the Oroville
Recreation Advisory Committee met Friday to hear reports from
the various member organizations overseeing them.
… Aaron Wright of the California Department of Parks and
Recreation said that several of the recently reopened areas
near the dam have received a good amount of traffic.
The earthquakes hit just days after last year’s
near-catastrophe at Oroville Dam, when the spillway cracked
amid heavy rains and 188,000 people fled in fear of flooding.
The timing of the two small tremors about 75 miles north of
Sacramento was curious, and frightening.
The new year will mark a half-century since a “seismic” shift
in geology unfolded. Eldridge Moores was a key thinker in that
shift. … I [Craig Miller] got another dose of that
enduring youthfulness two years ago, chasing after him as he
led me – at a brisk pace — down to the Yuba River bank.
We were in search of the kind of “incompetent” rock that
contributed to the catastrophic collapse of two spillways at
Dam inspectors overlooked technical details during safety
evaluations that could have identified structural problems with
the Oroville Dam spillway before it broke during heavy rains in
February 2017, according to an assessment ordered by the
Federal Energy Regulatory Commission. FERC assembled an
independent, six-person panel to assess the safety inspections
that are required every five years for the roughly 2,500
hydropower facilities that FERC regulates.
Employees of the state Department of Water Resources, with the
help of firefighting crews, were cutting brush and watering
down landscapes around Lake Oroville to prevent the
117,000-acre blaze from damaging the reservoir’s
infrastructure, including the 770-foot-tall Oroville Dam.
A trial date has been set to hear several lawsuits against the
state Department of Water Resources over the Oroville Dam
crisis. The court scheduled the trial for June 1, 2020 during
the second case management conference Friday in the Sacramento
County Superior Court.
Federal regulators are raising new concerns about the troubled
Oroville Dam, telling California officials their recently
rebuilt flood-control spillways likely couldn’t handle a
mega-flood. Although the chances of such a disastrous storm are
considered extremely unlikely — the magnitude of flooding in
the federal warning is far greater than anything ever
experienced — national dam safety experts say the Federal
Energy Regulatory Commission’s concerns could have costly
repercussions for California.
State officials said Wednesday the damaged Oroville Dam
flood-control spillway is ready for the rainy season, and will
be able to fully blast water down its half-mile long concrete
chute for the first time in nearly two years if lake levels
rise. Work on the adjacent emergency spillway is ongoing.
A request from the state Department of Water Resources to
temporarily make more than 50 miles of trails in Oroville open
to multiple user groups has been denied by the Federal Energy
Regulatory Commission. DWR proposed this with backing from the
Oroville Recreation Advisory Committee, or ORAC, as a
compensation for trail closures as a result of the 2017
Oroville Dam spillway emergency.
This tour explored the Sacramento River and its tributaries
through a scenic landscape as participants learned about the
issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of
California’s water and feed into two major projects: the State
Water Project and the federal Central Valley Project. Tour
participants got an on-site update of Oroville Dam spillway
The state Department of Water Resources still expects to meet
its quickly approaching Nov. 1 deadline to have all concrete
placed on the Oroville Dam’s main spillway. Crews began by
placing permanent concrete slabs at the bottom of the spillway
of the nation’s tallest dam, making their way to the top. Now,
the upper chute is about three-quarters of the way complete,
DWR reported in a moderated media call on Wednesday.
Gov. Jerry Brown has signed into law Sen. Jim Nielsen’s bill to
form a citizens advisory commission for the Oroville Dam.
Senate Bill 955 creates a 19-member commission to provide a
forum for residents and state officials to discuss reports,
maintenance and other ongoing issues related to the dam.
Fixing the Oroville Dam spillway wrecked by storms in 2017 will
cost $1.1 billion — a $455-million hike from initial estimates
— the state Department of Water Resources announced Wednesday.
The swelling cost can be blamed on design changes that have
been made over the last 16 months and damage to the facility
near Oroville, Calif., that was far more extensive than
initially presumed, the department said.
The north side of the Oroville Dam Diversion Pool will be open
to hikers and bicycles for the Labor Day weekend, and the pool
itself will be open for kayakers. … On Saturday from 8
a.m. to noon, a walk guided by State Parks staff will explore
vestiges of pioneer settlements, grandiose Gold Rush schemes,
and the train tunnel during the construction of the dam, as
well as native plants and animals seen along the way.
Butte County has filed another lawsuit against the state
Department of Water Resources, this time for damages from the
Oroville Dam crisis that continue to increase. The county is
seeking compensation for damage to its roads, which heavy
equipment is still utilizing for construction efforts, and also
for costs associated with responding to the spillway emergency
in February 2017.
A 30-foot-wide section of temporary wall on the upper chute of
the Oroville Dam spillway fell over late last week, the state
Department of Water Resources confirmed on Monday. The collapse
did not impact construction deadlines and resulted in no
injuries, according to the department.
The local oversight committee spearheaded by Assemblyman James
Gallagher and Sen. Jim Nielsen had some suggestions this week
for the state Department of Water Resources on its assessment
of the Oroville Dam. This comes about a month after the
committee met for the first time on July 18.
Eighteen months after the dramatic failure of the spillways at
Oroville Dam in Northern California, a disaster that led to the
evacuation of 188,000 people, construction is on schedule to
complete the concrete work in the main spillway by Nov. 1.
… On Monday, Lake Oroville was 51 percent full, or 73
percent of its historic average for this date.
Crews have begun to place the final layer of concrete this week
on the upper portion of the Oroville Dam spillway chute. This
marks a “crucial milestone,” said Tony Meyers, project manager
for the recovery project for the state Department of Water
Resources, in a moderated media call on Wednesday.
Another attempt by the state Department of Water Resources to
have the Butte County District Attorney’s lawsuit against the
department thrown out was thwarted Friday. The civil suit stem
from the Oroville Dam crisis and the alleged 3.4 billion to 5.1
billion pounds of debris which fell from the collapsing
spillway into the Feather River in February 2017.
The independent review board hired by the state Department of
Water Resources to put outside eyes on an assessment which will
play a large role in the future operations of the Oroville Dam
has released its first report. Suggestions for infrastructure
changes like the construction of a second gated spillway are
expected to be considered through what DWR is calling a
comprehensive needs assessment.
Fran Obrigewitsch pulled up the most recent photo on her iPhone
of the Oroville Dam spillway, taken just two days before it
started to collapse last year. Her first chance to catch
another glimpse was Monday, as the state Department of Water
Resources reopened the stretch of Oro Dam Boulevard East that
offers views of the spillway to the general public for the
first time since the crisis began.
A historic first meeting between state Department of Water
Resources officials and local leaders as a committee solidified
that the community will have a say in the future of Oroville
Dam operations. … The committee is being led by co-chairs
Assemblyman James Gallagher, Sen. Jim Nielsen and DWR’s John
Enhancements to several Lake Oroville recreation areas are in
the works this summer as the state Department of Water
Resources makes good on its promise to improve lake access
ahead of the Oroville Dam relicensing. Some means of getting
more people out on the water include adding boat launch lanes
and parking spots and providing free shuttle services.
Phase two of construction on the Oroville Dam’s main and
emergency spillways is speeding along, as the Oroville
Mercury-Register got to see up close in a tour on Wednesday
guided by state Department of Water Resources officials. With
half of the main spillway currently a work in progress, the
department’s goal is to have the structure ready to use, if
needed, by Nov. 1 — just under four months away.
A local oversight committee will get to have a say as long-term
changes are considered for the Oroville Dam, after Sen. Jim
Nielsen and Assemblyman James Gallagher recently came to an
agreement with the state Department of Water Resources.
Concrete pouring is due to start Monday on the second half of
the Oroville Dam emergency spillway “splash pad.” That’s the
only milestone reported Wednesday during a media call on
progress to repair the emergency spillway and main spillway,
which sustained serious damage in February 2017.
An Inland Empire water wholesaler is poised to get a boost in
state funding for its effort to create a new local water supply
that would provide ecological benefits in Northern California.
The California Water Commission has tentatively approved nearly
$207 million in Prop. 1 water bond funds for the Inland Empire
Utilities Agency’s Chino Basin Conjunctive Use Environmental
Water Storage/Exchange Program.
Heading to Lake Oroville for the holiday weekend? It can be
tricky to keep track of what areas are open to the public, with
construction ongoing at the Oroville Dam spillways. To help
with your plans, here is some information on the accessible
trails, boat launches and other recreational areas.
A Butte County Superior Court judge will determine where
lawsuits against the state Department of Water Resources for
the Oroville Dam crisis will be considered in a written ruling.
This comes as Judge Tamara Mosbarger heard arguments on Friday
from plaintiffs and the defendant.
The largest proposal is an $8.8-billion bond for water supply
and storage efforts including water recycling, stormwater
capture, restoring fish habitats and repairing the spillways of
the Oroville Dam that were damaged in 2017.
The Diversion Pool below Oroville Dam and the trails on both
sides of it will be partially open Friday through the Fourth of
July, the Department of Water Resources announced Wednesday.
The report came during a conference call to update media on the
status of work to repair the spillways, which were heavily
damaged in February 2017.
The U.S. Senate passed on Monday the 2019 Energy and Water
Development appropriations bill, which requires an
independent risk analysis of Oroville Dam. Additionally, the
bill would order the Federal Energy Regulatory Commission to
report the findings of an independent panel reviewing the state
Department of Water Resources’ dam safety practices to the
The state Department of Water Resources announced plans on
Friday to draw Lake Oroville down to 808 feet elevation by
early next week. This is to provide a second point of access to
the upper chute of the Oroville Dam spillway, through the
radial gates, for construction.
The state Department of Water Resources has beefed up its
response to the independent forensic report on what caused the
Oroville Dam spillway failure last year. The report, released
on Jan. 5, described how insufficient maintenance and repairs
and faulty original design allowed water to seep through the
spillway’s cracks and joints. It also blamed “long-term
systemic failure” on the part of DWR, regulators and the dam
safety industry at large.
A lawsuit filed by Butte County District Attorney Mike Ramsey
against the state Department of Water Resources over
environmental damages resulting from the Oroville Dam spillway
crisis is moving forward in court. Butte County Superior Court
Judge Stephen Benson overruled DWR’s demurrer, which is
essentially a plea to have a case dismissed, through a written
ruling filed on May 31.
An excavator slid down the Oroville Dam spillway slope on
Sunday morning, resulting in minor injuries to its operator,
the state Department of Water Resources confirmed on Wednesday.
Erin Mellon, assistant director of public affairs for DWR, said
that the operator immediately got back to work after the
accident, which is currently under investigation by the
department and Kiewit Infrastructure West Co., the lead
contractor for the construction project.
Bald eagles booted out of their nest last year during the
Oroville Dam spillway crisis have proven to be quite the
resilient pair, making a new home for themselves and
successfully hatching two little ones. During the incident last
February, the state Department of Water Resources had to
reroute powerlines that used to cross the spillway slope.
The Oroville Strong! advocacy group is going by a new name and
hoping to increase its reach to those in the greater area who
have been affected by the spillway crisis. The new entity
called the Feather River Recovery Alliance will be headed by
some of the same leaders; however, it will be disassociated
from the Oroville Chamber of Commerce.
The opening of the Diversion Pool last weekend to kayakers and
hikers appears to have been a big success according to all
involved, and it may happen again. “We’ve already been
discussing it with our partners and probably will,” State Parks
District Superintendent Aaron Wright said Thursday, “but I
can’t commit to that now.”
Two bills proposed by Assemblyman James Gallagher, one of which
would have taken the State Water Project from the state
Department of Water Resources and another which would have
provided funding for school resource officers, failed on Friday
to pass through the Assembly Appropriations Committee.
The second and final phase of reconstruction continues at the
Oroville Dam spillways. … A flight over the location last
week during a break in Butte County Sheriff’s Office helicopter
training exercise, showed that much original concrete at the
top of the chute has been removed, along with the walls.
Californians this year will vote on not one but two water bond
measures totaling $13 billion. Given that the state still
hasn’t spent all of the $7.5 billion from the Proposition 1
water bond passed in 2014, it raises a crucial question: Does
California really need another $13 billion in water bonds?
In order to get boaters and swimmers back to Lake Oroville
after the Oroville Dam spillway was damaged in 2017, state
agencies have announced they will waive fees for the
recreational area on select days over the summer.
While work to repair the main Oroville Dam spillway will
largely be done by Nov. 1, in response to a question, the
Department of Water Resources clarified that work on the
emergency spillway will continue into 2019.
Construction work began just after midnight Tuesday morning on
phase 2 of the repairs to the Oroville Dam main spillway. The
Department of Water Resources had been granted permission by
federal and state regulators to start work May 8, and
contractor Kiewit Infrastructure West didn’t waste any time.
The Federal Emergency Management Agency recently told north
state congressmen Doug LaMalfa and John Garamendi that the
agency is still reviewing whether the state Department of Water
Resources is eligible for further reimbursement to fix the
Oroville Dam spillway.
The NOR-CAL Guides and Sportsmen’s Association and other
fishing groups had spent more than a year pressuring state dam
and fish-hatchery managers to raise extra fish to make up for
the ones the fishing groups say were lost after the Oroville
Dam spillway collapsed in February 2017.
A bill proposed by Assemblyman James Gallagher which would take
the State Water Project out of the hands of the state
Department of Water Resources passed unanimously on Tuesday
through a legislative committee. Assembly Bill 3045 passed 15-0
through the Assembly Water, Parks, and Wildlife Committee and
is now headed to the Assembly Appropriations Committee.
The extreme weather swings experienced by Californians the past
six years — a historic drought followed by drenching winter
storms that caused $100 million in damage to San Jose and
wrecked the spillway at Oroville Dam — will become the norm
over coming generations, a new study has found.
The U.S. Geological Survey over the last year has recorded
dozens of weak and shallow earthquakes near Oroville Dam and
its spillways. And nearly all the tremors — including a
magnitude-0.8 quake recorded Wednesday — share the same
designation: “Chemical explosion.”
While some construction continues at Oroville Dam, the bulk of
work under phase two is expected to begin May 8, state
Department of Water Resources officials said Wednesday in a
monthly media update call. This comes as DWR submitted an
updated 2017-2018 Lake Oroville operations plan on Tuesday to
the Federal Energy Regulatory Commission and the California
Division of Safety of Dams for approval.
After a spring storm system dumped 5 to 7 inches of rain into
the Feather River basin over the weekend, state officials said
Sunday they likely won’t have to use the partly rebuilt flood
control spillway at Oroville Dam after all.
Northern California is bracing for a major spring storm that is
expected to dump several inches of rain on burn-scarred areas
of wine country and could present the first test of the
partially repaired spillway at the nation’s tallest dam.
Flash floods, rising rivers and mudslides are possible across
Northern California as a storm that’s more January than April
barrels in from the Pacific, the National Weather Service
warns. “This is not the time of year when we see these big
precipitation events,” said Daniel Swain, a climate scientist
Oroville Dam operators said Tuesday they may have to release
water over a partially rebuilt spillway for the first time
since repairs began on the badly damaged structure last summer.
Department of Water Resources officials said anticipated storms
could trigger releases this week or next.
With a pounding storm headed for California, state water
officials said Tuesday that Oroville Dam’s crumbled spillway
could get its first test since being rebuilt in the wake of
last year’s near-catastrophe.
The flows have been shut off through the Hyatt Powerhouse at
the base of Oroville Dam, and the lake is beginning to rise.
And that’s all by design, according to the state Department of
Kiewit Infrastructure West Co. said on Wednesday that
construction of the underground wall below the Oroville Dam
emergency spillway completed in early March. The 1,450 feet
long wall, drilled 35-65 feet into bedrock, is one preventative
measure against the type of erosion that occurred there last
year, should the emergency spillway ever be used again.
A bill introduced by Sen. Jim Nielsen that would create a
citizens advisory commission for the Oroville Dam was amended
in the Senate last week. This comes as the Oroville Dam
Coalition has been lobbying over the past year for more
community involvement, including through a citizens oversight
committee, as a reaction to the spillway crisis in February
State Parks workers were pulling cable up a launch ramp at
Bidwell Marina Thursday because the water level in Lake
Oroville is on the rise. March’s storms have brought the lake
level up almost 13 feet since the start of the month, according
to the Department of Water Resources website.
The state Department of Water Resources submitted its plan to
the Federal Energy Regulatory Commission on Tuesday to address
findings in the independent forensic report. The extensive
forensic report, released on Jan. 5, blamed “long-term
systematic failure,” including faulty design and insufficient
maintenance, for the Oroville Dam crisis in February 2017.
On the 90th anniversary of the catastrophic failure of the St.
Francis Dam, dam safety experts worry that the Oroville Dam
crisis showed that some of those crucial lessons have been
forgotten — or were never retained in the first place.
California Gov. Jerry Brown signed legislation Monday that
seeks to beef up dam inspections following a near disaster that
caused the evacuation of almost 200,000 people living
downstream from the tallest one in the United States. The
measure implements several recommendations from experts who
reviewed the crisis at Oroville Dam last year.
Though the final phase of repair work on the main spillway at
Lake Oroville is now on the back burner until spring,
Department of Water Resources officials said crews are making
significant progress on repairing the emergency spillway.
Until February 2017, the calls that came to Butte 2-1-1 ranged
from quelling stress, and finding support organizations, to
locating low-cost diapers. But for a few weeks after the
Oroville Dam spillway disaster, the calls were desperate,
seeking evacuation routes, hunting for surviving relatives, and
wondering when residents could return home.
Assemblyman James Gallagher rounded up a group of bipartisan
legislators to visit Oroville on Thursday, where they met with
community members and toured the now-infamous dam.
Representatives of districts ranging from southern to northern
California came to better understand the place where the
evacuation of about 188,000 people occurred just over a year
Locals who lost business or saw their property value decrease

dam in a generation, federal regulators who oversee
California’s half-century-old, towering Oroville Dam say they
are looking hard at how they overlooked its built-in weaknesses
Butte County District Attorney Michael Ramsey has filed a
lawsuit against the California Department of Water Resources
seeking $34 billion to $51 billion in civil penalties for
environmental damage following the failure of the Oroville Dam
spillways last February.
Butte County prosecutors are seeking up to $51 billion in fines
and penalties against California’s water agency for damage
caused to local river-based wildlife after the Oroville dam
spillway failure last year, officials said.
Butte County District Attorney Mike Ramsey announced Wednesday
that his office filed a lawsuit against the state Department of
Water Resources for environmental damages to the Feather River
as a result of the Oroville Dam crisis.
Nine individuals or entities from Yuba-Sutter are suing the
California Department of Water Resources for more than $27
million in damages suffered as a consequence of the Lake
Oroville spillway crisis last February.
Last winter, California’s Democratic leaders were feeling
cautiously optimistic that they could work with President
Donald Trump to spur desperately needed infrastructure
investment in the state. One year into the Trump
administration, the prospects for bipartisan partnership on the
issue have dimmed.
Oroville Dam’s battered flood-control spillways have been
largely rebuilt, but the cost of last February’s near-disaster
keeps rising. On Friday, state officials put the total price
tag at $870 million.
Local leaders are pressing the state Department of Water
Resources for details on how residents will be involved in the
community needs assessment. Department officials have said that
constructing additional infrastructure at Oroville Dam,
including a second gated spillway and a fully lined emergency
spillway, would be considered as part of the assessment.
The state Department of Water Resources could have lost control
of the spillway radial gates for days during the Oroville Dam
crisis if crucial power lines had gone down, according to
department officials. DWR leaders Cindy Messer and Joel Ledesma
stated this Jan. 10 during a legislative oversight hearing on
the dam at the State Capitol.
After a 5-month stint running California’s Department of Water
Resources, Grant Davis was reappointed Tuesday to his prior job
as general manager of the Sonoma County Water Agency. The Board
of Supervisors, acting as directors of the Water Agency,
unanimously agreed to reinstate Davis, commending him as a
trusted leader with a proven track record in the area.
An investigation into last winter’s near catastrophe at
Oroville Dam uncovered a litany of problems with how the dam
was built and maintained, but one of them stands out: Even as
workers built the dam, they were raising alarms about the
eroded, crumbling rock on which they were directed to lay
concrete for the 3,000-foot-long main flood control spillway.
The city of Oroville filed a lawsuit against the state
Department of Water Resources Wednesday which alleges
fabricated maintenance reports, racial discrimination and
decades of mismanagement led to the Oroville Dam spillway
failure last February.
Signaling what could be a wave of lawsuits arising from last
year’s spillway crisis, the city of Oroville is planning to
file a complaint Wednesday against the state Department of
Water Resources for damages it says it suffered during and
after the emergency. About 188,000 people were evacuated from
communities along the Feather River after the failure of
Oroville Dam’s main spillway last Feb. 7.
The verdict is in and California stands convicted of gross
negligence in the construction and maintenance of the nation’s
highest dam, Oroville. The dam on the Feather River came very
close to failing last year, forcing the evacuation of a
quarter-million people living downstream. … Clearly, for
decades there was no willingness at DWR [California Department
of Water Resources] to acknowledge the fundamental nature of
the flaws and spend money to repair them.
Grant Davis, director of the California Water Resources
Department, was replaced Wednesday just days after an
independent investigation of the Oroville dam spillway incident
last year found that a flawed safety culture contributed to the
disaster. The agency said Gov. Jerry Brown replaced Davis with
Karla Nemeth, who has been deputy secretary and senior advisor
for water policy at the California Natural Resources Agency
Starting with the damaged Oroville Dam, California seemed to
careen from disaster to disaster in 2017. The dam’s spillway
alone is projected to cost more than $500 million to repair.
… [Gov. Jerry] Brown maintains that the state will face more
weather-related extremes in years ahead because of climate
California water officials have always insisted public safety
was their only concern as they struggled with the crisis
unfolding last February at Oroville Dam. The forensic team
investigating what happened at Lake Oroville, however, has
pinpointed another factor guiding the decisions made by the
Department of Water Resources: the state’s desire to continue
shipping water to faraway farms and cities that rely on
deliveries from the reservoir.
The spillway failures at Oroville Dam that prompted tens of
thousands to flee for their lives last winter were the result
of years of mistakes, lax inspections and lazy repairs by the
state’s water agency, a team of independent dam experts
reported Friday. Their conclusions: State water managers should
not have built the dam’s primary spillway on faulty
Less than nine months after two massive holes formed in Lake
Oroville’s main spillway, construction crews wrapped up their
first phase of rebuilding it. Some local residents have
expressed concerns that the quick turnover could result in
faults or design flaws, but an official with the Department of
Water Resources said if any crew can accomplish the feat, it
would be Kiewit Infrastructure West Co.
The independent team of experts investigating the dramatic
failure of the spillways last February at Oroville Dam that led
to the evacuation of 188,000 people has concluded that
California water officials were “overconfident and complacent”
and gave “inadequate priority for dam safety,” according to a
final report released Friday.
