Hydroelectric power is generated by the ability to turn falling
water into electricity and in California accounts for about 15
percent of the state’s power supply annually.
The second-largest river in California has sustained Native
American tribes with plentiful salmon for millennia, provided
upstream farmers with irrigation water for generations and
served as a haven for retirees who built dream homes along its
banks. With so many competing demands, the Klamath River has
come to symbolize a larger struggle over the increasingly
precious water resources of the U.S. West…
The falling cost of renewable energy and continued decline of
manufacturing renders many of these structures unnecessary.
Others require expensive maintenance. Seven in 10 are more than
50 years old and many are falling into disrepair, according to
the American Society of Civil Engineers…
If corporations can have the rights of people under the law,
why not rivers? The question made sense to Will Falk, and he
answered it yes. Falk is a lawyer, and he got to represent the
Colorado River in a lawsuit. So he spent time along the river,
in something of a conversation with it. Falk tells the story in
his book How Dams Fall.
Tuolumne Utilities District announced on Tuesday that it has
entered into exclusive negotiations with Pacific Gas and
Electric Co. to acquire the Phoenix Hydroelectric Project,
which would include pre-1914 water rights on the South Fork of
the Stanislaus River…
Tulare County-based Kaweah River Power Authority has requested
Federal Energy Regulatory Commission (FERC) approval to
transfer the license for their 20MW hydroelectric plant at
Kaweah Lake’s Terminus Dam to Canadian-based Ontario Power
Generation.
A proposal to pump water out of Nevada’s fragile Walker Lake to
generate hydropower to sell in California won preliminary
approval from federal regulators. On Friday, the Federal Energy
Regulatory Commission issued a preliminary permit and granting
priority to file for the proposed Walker Lake Pumped Storage
Project.
The pit was a bustling iron mine once, churning out ore that
was shipped by rail to a nearby Kaiser Steel plant. When steel
manufacturing declined, Los Angeles County tried to turn the
abandoned mine into a massive landfill. Conservationists hope
the area will someday become part of Joshua Tree National Park,
which surrounds it on three sides. Steve Lowe has a radically
different vision.
In a Feb. 28 filing, the Klamath River Renewal Corporation,
formed to shepherd the removal of four hydroelectric dams from
the Klamath River in Northeern California and Southern Oregon,
submitted key budget information to the Federal Energy
Regulatory Commission. … This filing is another concrete step
toward implementing the amended Klamath Hydroelectric
Settlement Agreement (KHSA), removing the dams and restoring a
free-flowing Klamath River, KRRC officials said.
Silicon Valley water officials assured the public Tuesday they
have enough water to avoid shortages this summer, even after
federal regulators announced that Anderson Reservoir, the
region’s largest, must be completely drained beginning this
fall because of the risk its dam might collapse in a major
earthquake.
The contraption, reminiscent of Rube Goldberg, would produce
two of Southern California’s most precious and essential
resources: water and electricity. … The idea, developed by
Silicon Valley-based Neal Aronson and his Oceanus Power & Water
venture, caught the attention of the Santa Margarita Water
District. The agency quickly saw the project’s viability to
fill a void.
Though the process leading to removal of the Klamath Dams
continues to march forward, numerous citizens in Siskiyou
County have continued fighting to keep the dams in place. Many
of those dam advocates are members of the Siskiyou County Water
Users Association, which in January hosted a presentation about
an alternative fish passage technology the association believes
could “make it possible” for the dams to remain.
State Sen. Scott Wiener will unveil legislation today to let
the state of California seize control of the embattled utility
PG&E. Wiener’s bill … would use eminent domain to force
the company’s stockholders to sell their shares to the state of
California, which would then take over operations.
Some local residents are organizing to oppose a twice-rejected
proposal for a Lake Elsinore hydroelectric plant. The Lake
Elsinore Advanced Pumped Storage project, more commonly known
as LEAPS, was tossed aside by the Federal Energy Regulatory
Commission nearly a decade ago in 2011.
The main focus of the program are the barriers to fish passage
for salmon from Friant Dam to the ocean and back again. There
are three key barriers: the East Side Bypass Control Structure
which is in the flood bypass; Sack Dam, which is the intake for
Arroyo Canal for Henry Miller irrigation system; and Mendota
Dam which controls Mendota Pool. The program also needs to
ensure enough habitat for the fish when they return to complete
their life cycle,
Stanislaus Superior Court Judge Roger M. Beauchesne issued his
decision Dec. 30 in the lawsuit filed by Andrew Hobbs and Dave
Thomas. Each sued the MID in 2016, and their lawsuits were
combined into one. … Beauchesne ruled the subsidy was an
illegal tax under California law because the MID had not sought
voter approval for electric customers to subsidize irrigation
water customers.
In the United States, many of the structures that were once
engineering marvels are nearing the age most humans decide to
retire. Despite steadily increased budgets for dam repair and
maintenance, over the past four decades more than a 1,000 have
failed … Although some dams are having critical maintenance
done, states and private entities are also coming up with a
different solution: take them down. California, once a
bastion of dam building, took down 35 dams just last year,
making it the leader in dam removals in 2018.
Two wildlife advocacy groups Wednesday announced their intent
to sue the Riverside County Flood Control & Water Conservation
District, as well as other regional and federal government
agencies, for allegedly putting a fish species’ habitat at risk
with the release of water from the Seven Oaks Dam.
Communities sprout up and sometimes wither away, but in 1972,
the small community of Cedar Springs met its demise when it was
swallowed up by a lake. The San Bernardino Mountains community
was located at the confluence of the west fork of the Mojave
River, Sawpit Canyon, and Miller Canyon, about 4 miles
northwest of Crestline. Today, the location is under the waters
of Silverwood Lake, near the boat launch ramp.
The Feather River Recovery Alliance has filed a motion to
intervene with the Department of Water Resources’ pending
application to re-license operation of the Oroville Dam. …
The motion requests that the Federal Energy Regulatory
Commission reopen the licensing process that was conducted over
a decade ago, and prior to the community becoming aware of
safety concerns at the Oroville Dam.
CalTrout has identified Scott Dam, which impounds Eel River
water in Lake Pillsbury, as one of five aging dams it considers
“ripe for removal,” especially in the wake of PG&E’s
license surrender. There is, however, a potential middle course
backed by Friends of the Eel River, a Eureka-based nonprofit
that has long called for the dam’s removal.
Native American tribes, environmentalists, state and federal
agencies, river rafters and others say they have significant
concerns about proposals to dam a Colorado River tributary in
northern Arizona for hydropower.
Exactly what the Potter Valley Project will look like in the
future is not set in stone. The partnership is committed to
identifying solutions that meet the needs of the communities
and wildlife affected by the project’s operations.
During days when solar panels feed more energy into the grid
than utilities want to buy, the projects would use the excess
power to pump water from Walker Lake or Pyramid Lake into the
newly constructed reservoirs. Once there, the water would sit
as a giant pool of potential energy. When demand for power
increased at night as solar production waned, the water could
be released downhill and run through a power plant.
Small shallow lakes dominate the world’s freshwater area, and
the sediments within them already produce at least one-quarter
of all carbon-dioxide, and more than two-thirds of all methane
released from lakes into our atmosphere. The new research,
published in the journal PNAS, suggests that climate change may
cause the levels of greenhouse gases emitted by freshwater
northern lakes to increase by between 1.5 and 2.7 times.
The U.S. Bureau of Reclamation spent months working with the
National Marine Fisheries Service and U.S. Fish and Wildlife
Service to mitigate potential harm to endangered sucker fish in
Upper Klamath Lake, as well as threatened coho salmon in the
lower Klamath River. … However, the bureau now says it
received “erroneous data” from an outside source during
consultation, meaning it must scrap the plans and start over
again.
Hydropower is broadly considered to be much more
environmentally friendly than electricity generated from fossil
fuels, and in many cases this is true. However, a new study
reveals that the climate impact of hydropower facilities varies
widely throughout the world and over time, with some facilities
emitting more greenhouse gases than those burning fossil fuels.
PG&E said Thursday that a small powerhouse at the reservoir
had been shut down since a canal at the reservoir had been
damaged during last winter’s storms. The utility has determined
that the costs to repair the canal “outweigh the economic
benefit of (power) generation at the Kilarc powerhouse.”
A local coalition formed in the hopes of maintaining the most
important aspects of the Potter Valley Project is making
progress toward a two-basin solution, Janet Pauli told the
Ukiah City Council at its last meeting.
The latest public relations effort cost California water
ratepayers $29,000 to produce an eight-page color advertising
insert that ran in recent days in six Sacramento Valley
newspapers including The Sacramento Bee. … Critics argue it’s
inappropriate for a state agency to be spending public money on
an advertisement that they say serves little purpose other than
to try to make the government look good.
After touring film festivals in two dozen cities across the
country, the documentary, Visions of the Lost Sierra, will be
released online Wednesday for all to view. … Visions is a
short film exploring how the Wild and Scenic Middle Fork
Feather River has connected communities and inspired outdoor
enthusiasts for generations.
Hydropower facilities store water in reservoirs in order to
release it in a constant flow and produce energy consistently.
If wind turbines and solar panels, paired with battery storage,
took the pressure off of these facilities to fill the needs of
the grid during a drought, more of that water could be released
downstream for agricultural use, preventing further groundwater
depletion.
The Mojave Water Agency on Thursday cut the ribbon on its Deep
Creek Hydroelectric Clean-Energy System, a project that
produces electricity from California Aqueduct water and
replenishes the groundwater in the Victor Valley.
Today, annual salmon runs in Eel River that once may have
totaled a million or so adults consist of a few thousand.
Lamprey eels, too, have dwindled. Now, there is serious talk of
removing Scott Dam, owned by PG&E since 1930. For fishery
proponents, such a river makeover is the optimal way to revive
the Eel’s salmon runs.
In a letter to the California Public Utilities Commission
shared Tuesday, the mayors and city supervisors argued that
PG&E ― beset by massive bankruptcy and public outrage over
its role in deadly wildfires and mismanaged forced power
outages ― would function better as a customer-owned utility
than a business focused on paying dividends to its
shareholders.
The effects of the last drought are still obvious in
California’s agricultural belt. … From this perspective, the
federal government’s plan to increase the storage capacity of
Lake Shasta, created by the Shasta Dam on the Sacramento River,
is both sensible and compassionate.
The U.S. Bureau of Reclamation can’t charge Central Valley
Project power customers disproportionately more than water
customers in order to fund its environmental efforts, the
Federal Circuit said Nov. 6. The law requires the Bureau to
charge customers in proportion to what they pay to fund the
network of dams, reservoirs, canals, and water power plants as
a whole, the U.S. Court of Appeals for the Federal Circuit
said.
The record of the hydropower industry on America’s rivers and
streams is not one of protecting and preserving natural
ecosystems. It is, in fact, exactly the opposite.
Just outside Grand Canyon National Park in Arizona, a
year-round, mineral-rich spring turns the Little Colorado River
a vivid turquoise. This final stretch, about 10 miles from the
river’s confluence with its larger relative, is one of the
West’s spectacular waterways, with bright water flowing below
steep red-rock cliffs. But the view will change dramatically if
a Phoenix-based company builds a proposed hydropower project.
Prior to a commission meeting earlier this year, the Commission
hadn’t met since 2010, according to Curtis Anderson, commission
member representing the California side of the river. …
“We’re seeing if we can be helpful by at least providing
information and providing an opportunity for people to raise
concerns concerning the Compact itself,” Anderson said.
Today’s noisy partisan divide concerns me and makes the thought
of meaningful collaboration across parties seem impossible.
However, the largest river restoration project in history,
spanning the California-Oregon border, tells a hopeful story
offering a blueprint for political, conservation and economic
progress.
The decadeslong Pacific Northwest salmon war may be nearing the
end. But it’s economics, not fish, that could be the demise of
four dams at the center of the fight. The dams on the Lower
Snake River — besieged by conservationists and biologists for
killing fish — are now battered by falling prices for renewable
energy, skyrocketing replacement costs for aging turbines and a
growing tab for environmental mitigation.
Aging water treatment systems, failing pipes and a slew of
unregulated contaminants threaten to undermine water quality in
U.S. cities of all sizes. … Still, with only a handful of
exceptions, “water systems aren’t designed to focus on health,
they’re focused on cost-containment,” says Seth Siegel, whose
book “Troubled Water,” released this month, examines the
precarious state of water infrastructure in the U.S.
The Colorado River serves over 35 million Americans before
reaching Mexico – but it is dammed at the border, leaving
locals on the other side with a dry delta.
Warmer-than-average temperatures are forecast for much of the
U.S. this winter according to NOAA’s Climate Prediction Center.
… Drier-than-average conditions are most likely for
Louisiana, parts of Texas, Mississippi, Arkansas and
Oklahoma as well areas of northern and central California.
The Bureau of Land Management (BLM) issued a right-of-way grant
(ROW) Wednesday that allows for the construction of various
facilities on 711 acres east of Klamath Falls, according to a
news release. … The ROW grant is part of the Swan Lake North
Hydro LLC proposal to develop a 393.3-megawatt hydropower
generating facility…
The White House has begun reviewing a plan to change the way it
issues environmental permits for infrastructure projects. If
the proposal is finalized, it could speed up National
Environmental Policy Act reviews for roads, bridges, ports,
pipelines, power lines, Internet trunks, and water systems.
Stop me if you’ve heard this one before: Critical U.S.
infrastructure is dilapidated and unsafe. Regulation is week,
and enforcement is weaker. Everyone agrees on the need for
action, and climate change will only make the problem worse.
but no one seems to do anything about it. Sadly, this has
become a familiar story. Take dams for instance.
Alicyn Gitlin, conservation coordinator for the Sierra Club’s
Grand Canyon Chapter, said the project would threaten an
endangered species, interfere with the Grand Canyon’s already
degraded hydrology and damage sites held sacred by two Arizona
tribes.
A staggering number of Chinook salmon are returning to a
California river that hasn’t sustained salmon for decades due
to agricultural and urban demands, giving biologists hope that
threatened fish are finally spawning in their native
grounds without human help.
Pumped Hydro Storage LLC is seeking approval from the Federal
Energy Regulatory Commission to study the sites east of Grand
Canyon National Park over three years. None of it will move
forward without permission from the Navajo Nation. Navajo
President Jonathan Nez said he’s been briefed by tribal
economic development officials about the proposals — but hasn’t
talked with anyone from Pumped Hydro Storage.
Anthony Burdock, Project Manager for the Isabella Dam Safety
Modification Project, presented a program outlining
catastrophic dam failures and how those failures were used to
mold the dam safety regulations that now govern the nation’s
dams, including Isabella Dam.
How does one achieve temperature and flow targets for listed
species with such different requirements, while also meeting
the needs of human water users? A recent study sought to
achieve an equitable solution by using a multi-objective
approach to identify trade-offs and model an optimal dam
release scenario to meet the needs of salmon, sturgeon, and
humans…
Environmental groups that have long pushed to bring down a huge
dam along the Colorado River are suing the federal government,
alleging it ignored climate science when approving a 20-year
operating plan for the dam near the Arizona-Utah border.
Following losses in court, a Fresno-based irrigation district
has backed off its plans to do an environmental study on
raising the height of Shasta Dam. The Westlands Water District
announced Monday that it has stopped working on the report
because it could not meet the U.S. Bureau of Reclamation’s
schedule for the project.
For years, the Interior Department resisted proposals to raise
the height of its towering Shasta Dam in Northern California.
The department’s own scientists and researchers concluded that
doing so would endanger rare plants and animals in the area…
But the project is going forward now, in a big win for a
powerful consortium of California farmers that stands to profit
substantially…
The California Natural Resources Agency is hosting an inaugural
public forum designed to address issues related to the Oroville
Dam, according to a press release from the CNRA.
A Phoenix company wants to build two hydroelectric dams less
than five miles from the eastern border of Grand Canyon
National Park, submerging several miles of the Little Colorado
River and the endangered fish habitat it protects.
Utah’s proposed Lake Powell pipeline will cost less to build
and be easier to permit under a decision announced Wednesday to
cut major hydropower components from the controversial project
that would move 86,000 acre-feet of Colorado River water to St.
George.
A plan to remove four dams on the Klamath River – one of the
most ambitious river restoration projects ever attempted – is
either mocked or praised depending on the audience. It will
expand salmon habitat or destroy a fishery. The only certainty
is that lives will change forever.
I’m writing to express our tribe’s dismay at Gov. Gavin
Newsom’s announcement that he plans to veto Senate Bill 1. …
Vetoing this bill will green-light President Trump’s plan to
divert even more water from our struggling rivers for
industrial agriculture. Many well-respected fish biologists and
environmentalists have concluded Trump’s attempt to ignore the
best science and rewrite the rules will essentially be an
“extinction plan” for Chinook salmon and other threatened fish.
Some 45,000 to 50,000 spring-summer Chinook spawned here in the
1950s. These days, the average is about 1,500 fish, and
declining. And not just here: Native fish are in free-fall
throughout the Columbia River basin, a situation so dire that
many groups are urging the removal of four large dams to keep
the fish from being lost.
Removing the four aging hydroelectric dams from the river would
significantly improve ecological and geomorphic conditions
throughout the Klamath watershed and play a key role in
returning salmon to stable population levels.
The Round Valley Indian Tribes announced this week that they
have signed an agreement to join with users of both the Eel
River and Russian River to seek a “Two-Basin Solution” for the
re-licensing of the Potter Valley Hydroelectric Project, which
diverts water from the Eel River into the Russian River.
Water managers across the state face new and more extreme
challenges as the climate warms—from balancing the sometimes
conflicting needs of urban, agricultural, and environmental
water users to reducing risks from fires, floods, and droughts.
We talked to Grant Davis, general manager of the Sonoma County
Water Agency, about how his agency is approaching these
challenges comprehensively, at the scale of the entire
watershed.
Today, the California Department of Water Resources began
assessment work on Pyramid Dam’s spillways in Los Angeles
County as part of a statewide effort to reduce seismic and
hydrologic risk to State Water Project facilities spanning 705
miles throughout California.
Now, some are arguing that the bill should be stripped of its
longstanding provision applying the State’s own Endangered
Species Act to the operations of the federal Central Valley
Project. Here’s why that’s a terrible idea.
In the Sacramento River near Redding this spring, water
districts, government agencies and others collaborated to
construct the Market Street Gravel Project to benefit fish. …
Reclamation District 108 Deputy Manager William Vanderwaal said
that to complete the $429,000 project, 12,000 tons of gravel
were placed into the river and developed as new spawning
habitat for chinook salmon and steelhead trout.
The Bonneville Power Administration, the independent federal
agency that sells the electricity produced by the dams, is
careening toward a financial cliff. BPA is $15 billion in debt,
facing a rapidly changing energy market increasingly dominated
by wind and solar and a desperate need to maintain aging
infrastructure that’s expected to cost $300 million to maintain
and upgrade by 2023.
Water users in the Colorado River Basin have survived the
drought through a combination of water storage infrastructure
and voluntary actions to protect reservoir storage and water
supply. Adoption of drought contingency plans this summer,
developed over years of collaborative negotiation, takes the
next step by implementing mandatory action to reduce risk and
protect limited water supplies.
The majestic beauty of the Sierra
Nevada forest is awe-inspiring, but beneath the dazzling blue
sky, there is a problem: A century of fire suppression and
logging practices have left trees too close together. Millions of
trees have died, stricken by drought and beetle infestation.
Combined with a forest floor cluttered with dry brush and debris,
it’s a wildfire waiting to happen.
Fires devastate the Sierra watersheds upon which millions of
Californians depend — scorching the ground, unleashing a
battering ram of debris and turning hillsides into gelatinous,
stream-choking mudflows.
Federal scientists pulled no punches in their report: The Trump
administration’s plan to send more water to San Joaquin Valley
farmers would force critically endangered California salmon
even closer to extinction, and starve a struggling population
of West Coast killer whales.
The Lake County Board of Supervisors approved an amended
resolution Tuesday that will open the door for Lake County to
join a group vying to take over responsibility for the Potter
Valley hydroelectric project.
Westlands Water District says a preliminary injunction ordering
it to stop work on an environmental impact report may prevent
it from helping to pay for raising the height of the dam,
according to the appeal filed last week.
California’s rivers and streams have experienced enormous
changes over the past 150 years, and a warming climate brings
new challenges. We talked to Ted Grantham—a river scientist at
UC Berkeley and a member of the PPIC Water Policy Center
research network—about the state of the state’s rivers.
In a joint statement, the local utility providers announced
that the Chili Bar Hydroelectric Project — a dam, reservoir,
spillway and powerhouse that generates electricity north of
Placerville on the South Fork of the American River — would be
changing hands after SMUD’s board of directors voted Thursday
evening to greenlight the purchase.
For five decades, PG&E paid for and operated the Colgate
Powerhouse in exchange for the revenue generated by the
hydroelectric generation. But now, instead of tens of millions
of dollars flowing out to the utility, that agreement has
expired and the revenue, potentially as much as $30 million per
year, is flowing back into the Yuba Water Agency.
Removing four hydroelectric dams along the lower Klamath River
in Southern Oregon and Northern California is expected to cost
just under $434 million and could happen by 2022, according to
a new filing with the Federal Energy Regulatory Commission.
A plan to raise and expand California’s largest reservoir is on
hold as federal officials look for partners to share in the
$1.4 billion cost. The federal Bureau of Reclamation also must
grapple with opponents who have sued, saying the Shasta Dam
project violates state law.
Environmentalists have raised concerns about the project’s
costs, and the fact that it would submerge 1,245 acres of oak
woodlands… But the Santa Clara Valley Water District, a San
Jose government agency that provides water to 1.9 million
Silicon Valley residents, says the reservoir is needed to store
more water as insurance against California’s next drought.
Next spring, the Yurok Tribe will begin its Redwood Canoe
Adventure Tour and it will utilize six hand-crafted redwood
canoes made using traditional tribal tools and techniques. …
According to the tribe, it’s an opportunity you won’t find
anywhere else in the world due to the unique relationship
between the Yurok people and the Klamath River.
In a weather anomaly verified for the first time, a weather
station in Siskiyou County recorded the highest annual
precipitation for California’s weather season. The weather
station at Stouts Meadow, located at an elevation of 5,400 near
the headwaters of the McCloud River, recorded 126.76 inches of
precipitation for the season.
A flexible, reliable water supply is essential to California’s
economy and to the job creation and job security goals of
California’s working families. … Of all the projects vying
for California’s attention, the proposed Sites Reservoir in
Northern California offers the most tangible benefits.
It is seen as a major move from one of the world’s biggest

During a recent trip to the Trinity River, I learned about the
many challenges facing its salmon and steelhead populations.
… A holistic approach to habitat restoration doesn’t rely on
a single silver bullet solution, but applies a comprehensive
set of actions that rely on collaboration
During a recent trip to the Trinity River, I learned about the
many challenges facing its salmon and steelhead populations.
… But there is hope and evidence of progress in realizing
ecological benefits of the past. A holistic approach to habitat
restoration doesn’t rely on a single silver bullet solution,
but applies a comprehensive set of actions that rely on
collaboration between local tribes, federal and state agencies,

In the appeal, DWR included updated reimbursement requests
totaling an estimated $1.11 billion to cover costs of the
Oroville spillways emergency response and emergency recovery
efforts. Final costs won’t be known until all project work is
complete, according to DWR officials.
The U.S. Army Corps of Engineers has granted Utah a 30-day
extension to provide desired documentation and plans related to
the Lake Powell Pipeline, according to state water officials.
As a small business owner who leads fishing tours for anglers
from within and beyond the region, I understand that taking
these dams out may lead to a short-term dip in business. But
the long-term benefits of dam removal outweigh the near-term
costs to my family and my livelihood.
The latest update of the California Water Plan was released
this past week. You may not have heard the news. You may not
even know there is a California Water Plan. And that’s just
fine, because it doesn’t mean a darn thing.
Cities such as San Francisco want to buy assets from the
bankrupt electricity provider to control the power supply for
their communities. An amendment inserted late in the
legislative process makes those purchases more difficult by
subjecting them to the approval of state regulators.
It’s not unusual to spot the national bird flying around Lake
Oroville every summer. What’s unusual this year is the amount
currently calling Lake Oroville home. Environmental scientists
from the Department of Water Resources Oroville Field Division
are keeping an eye on seven nesting pairs of bald eagles, four
of which are successfully raising a total of eight young
eaglets.
While California contemplates new dams for its thirsty future,
it’s also thinking about taking out old ones. Along with
advancing plans to demolish three dams atop the Klamath River,
there’s a movement to rethink and possibly take out a water and
power dam in the Mendocino County back country.
The updated guide contains dozens of best practices, grouped
into 15 main categories, that water and wastewater systems can
implement to reduce security risks to their IT and OT systems.
Each recommendation is accompanied by links to corresponding
technical resources.
The Eel River—once home to the state’s third-largest salmon and
steelhead runs, all of which are now listed as threatened―may
see the return of healthy fisheries in coming years. A unique
opportunity to remove a dam that blocks fish from reaching
spawning habitat has arisen. We talked to Curtis Knight,
executive director of CalTrout, about the situation.
For years, the people of the Northern San Joaquin Valley have
been trying to get hydropower recognized for what it is: the
original source of clean electricity. Our efforts have been
stymied by people who feel entitled to decide what is, or
isn’t, green enough. That’s why I have begun the process of
modifying our state Constitution to recognize safe, abundant,
carbon-free hydropower as a reliable source of renewable energy
in our fight against climate change.
Your perfect river might be one where you float gently along on
inner tubes, or maybe your style is to careen through raucous
rapids in an eight-person inflatable raft. No problem.
California has got it all when it comes to river rafting, from
gentle half-day float trips for first-timers and mellow family
adventures to adrenaline-pumping, white water, multi-day
thrillers.
Proponents have said SB 1 will keep Trump from delivering more
water to farms, thereby harming endangered fish. That sentiment
is exactly what makes SB 1 so dangerous. It relies on the
worn-out trope that California’s water issues boil down to
“farms versus fish.”
The water is coming straight from the Sierra Nevada Mountains
and is very cold, which is causing some concerns people hoping
to get into the water. But, the water itself, when used what
it’s intended for, has a great impact in our Central Valley.
There’s a new twist in the California-Trump brawl in the state
Legislature. It’s aimed at overriding the president’s power to
weaken environmental protections. Put simply, any federal
protections President Trump tried to gut would immediately
become state regulations in their original, strong form.
If you want to dam rivers, as we were inclined across much of
the 20th century, the location of the current Parker Dam on the
Lower Colorado River makes sense – a narrow gap just downstream
from the confluence of the Colorado and Bill Williams rivers on
the Arizona-California border.
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.
On the last Saturday in June, a road in Butte County was
opened. That in itself isn’t anything unusual. Roads are opened
and closed regularly around here. But it was the significance
of this road that makes it a remarkable occurrence. It was the
road over Oroville Dam.
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.
The Lake Hodges facility near San Diego, a relatively small 40
megawatt generating station, is one of 40 pumped storage
facilities around the United States, and its operator says it
is helping the state meet its ambitious goals. San Diego is
planning a larger system at another site, the San Vicente
reservoir, again using two water sources at different
elevations.
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.
The rapid proliferation of the quagga mussel has major
implications for power plant reliability. The U.S. Bureau of
Reclamation installed a groundbreaking solution at Parker Dam
in Arizona that virtually eliminated the invasive species from
hydropower cooling systems.
It will take as many as 13 water years exactly like this one to
erase the impacts of long-term drought in the West, Colorado
River District engineers say.
Since the turn of the 20th century, the Colorado River and its
tributaries have been dammed and diverted to sustain the growth
of massive cities and large-scale farming in the American
Southwest. Attempts to bend the river system to humanity’s will
have also led to all kinds of unintended consequences. In
Colorado’s Paradox Valley, those unintended consequences take
the form of earthquakes.
Oroville Dam is officially back open to the public two years
after it was forced to close due to the failure of the dam’s
main and emergency spillways. People can now walk and bike the
more than one-mile-long road across the dam crest. Public
vehicles will still not be allowed.
Last week three local entities — California Trout, Mendocino
County Inland Water and Power Commission (IWPC) and Sonoma
Water — announced they will be signing a project planning
agreement with the hopes of looking at pathways to relicense
the Potter Valley Project. The Potter Valley Project is a
hydropower project that sits in the middle of the Eel River and
Russian River watershed basins and is integral in providing
water to both Mendocino County and northern Sonoma County.
The city of San Diego and the San Diego County Water Authority
are assessing pumped-water energy storage as a way to integrate
more renewable power, stabilize the power grid, reduce
greenhouse gas emissions and foster economic growth. Their
proposed San Vicente Energy Storage Facility would take water
from the existing San Vicente Reservoir and use electricity to
pump it to a smaller, higher elevation reservoir.
In order to address the impacts of climate change on the
state’s water resources, the Department of Water Resources
(DWR) has been developing its own comprehensive Climate Action
Plan to guide how DWR is and will continue to address climate
change for programs, projects, and activities over which it has
authority.
Mono and Inyo counties were handed a reprieve by the Federal
Energy Regulatory Commission last Friday. The Commission’s
Division of Hydropower Licensing found Premium Energy’s
application for a closed loop system from reservoirs in the
Owens Gorge to the White Mountains “patently deficient.” That’s
the good news. The FERC did not find the project patently
deficient because of environmental or common sense reasons…
The plan calls for pumping 8 billion gallons of water in the
first few years, and more than 30 billion gallons over 50
years, from the aquifer adjacent to, and connected with, the
one beneath neighboring Joshua Tree National Park. … A better
use for the land, which ceased to be mined more than 30 years
ago, would be to return it to the fold and make it part of
Joshua Tree National Park.
In my 40 years at the California Department of Water Resources,
I have seen changes in climate that have convinced me that the
full picture is changing and our extrapolation methods are
losing value rapidly. This is especially true in extreme years,
wet or dry – such as 2015, when the statistics are just not
going to be accurate enough to meet our growing water
management needs.
States that share the river’s water finalized a big agreement
last month, but an even larger challenge determining the
river’s future is just around the bend, expert John Fleck
explains.
In an effort to combat climate change and reduce smog, former
Gov. Jerry Brown last year signed a landmark law that requires
California’s utilities to produce 60 percent of their
electricity from renewable sources like solar and wind by 2030.
But hydroelectric power from large dams doesn’t qualify as
renewable, because of another state law, passed nearly 20 years
ago, that aimed to protect salmon and other endangered fish.
That’s not right, says State Sen. Anna Caballero, D-Salinas.
The Humboldt County Board of Supervisors voted unanimously to
investigate becoming a stakeholder in the Potter Valley
project, a massive water development in the Eel and Russian
river basins. … The idea is to protect the Russian River’s
water supply for Potter Valley residents while mitigating the
effects of the Scott Dam on Eel River fish populations.
Members of Friends of the River and the Sierra Club are
planning a presentation on a controversial episode in Mother
Lode history, when activists unsuccessfully tried to prevent
flooding of a raftable section of the Stanislaus River by
rising water levels in New Melones Reservoir in the 1970s and
1980s. … The event is scheduled at 7 p.m. Wednesday this week
at Tuolumne County Library, 480 Greenley Road in Sonora.
An abandoned iron mine on the doorstep of Joshua Tree National
Park could be repurposed as a massive hydroelectric power plant
under a bill with bipartisan support in the state Legislature.
… The bill could jump-start a $2.5-billion hydropower project
that critics say would harm Joshua Tree National Park, draining
desert groundwater aquifers and sapping above-ground springs
that nourish wildlife in and around the park.
The Colorado River just got a boost that’s likely to prevent
its depleted reservoirs from bottoming out, at least for the
next several years. Representatives of seven Western states and
the federal government signed a landmark deal on Monday laying
out potential cuts in water deliveries through 2026 to reduce
the risks of the river’s reservoirs hitting critically low
levels.
Recently-appointed Interior Secretary David Bernhardt has
rescinded a letter of support that Obama-era Interior Secretary
Sally Jewell wrote in 2016. … Matt Cox is with the Klamath
River Renewal Corporation, the non-profit formed to implement
the dam removal agreement. He says rescinding Jewell’s letter
has no legal effect.
Tulare County Supervisors will vote to approve a letter of
support for proposed legislation that will bring up to $3.5
billion for water infrastructure improvements. The money comes
at a cost to California’s biggest undertaking — high-speed
rail.
After months of tense, difficult negotiations, a plan to spread
the effects of anticipated cutbacks on the drought-stricken
Colorado River is nearing completion. On Monday,
representatives of the seven states that rely on the river will
gather for a formal signing ceremony at Hoover Dam, the real
and symbolic center of the Lower Basin Drought Contingency
Plan.
Well, apparently we’re all about to die again. The internet
says so. And while the internet often says we’re all about to
die, and we don’t, for some reason people still unquestionably
believe the next scare to come down the information highway. So
it is with the latest local scare, involving the Oroville Dam
spillway.
Halting plans to remove four dams on the Klamath River was the
theme of a well-attended fundraising event hosted May 4 by the
Siskiyou County Water Users Association. Guest speakers,
including Congressman Doug LaMalfa, Siskiyou County Supervisor
Brandon Criss, former Klamath County Commissioner Tom Mallams
and Attorney James Buchal, author of “The Great Salmon Hoax”
discussed problems they foresee with dam removal which they
believe is far from a done deal.
California Trout, Mendocino County Inland Water & Power
Commission, and Sonoma Water have officially put a foot forward
to explore a planning agreement for the project’s future. The
coalition is championing a “two-basin solution” that could
mitigate the effects of the Scott Dam on fish populations in
the Eel River while ensuring that the Russian River basin
doesn’t lose its water supply, which Potter Valley residents
have relied on for over 100 years.
The DCP … provides assurance against curtailments for water
stored behind Hoover Dam. This is especially important for the
Southern California water agencies, whose ability to store
water in Lake Mead is crucial for managing seasonal demands.
Some significant challenges must still be addressed, however.
California Trout, Mendocino County Inland Water & Power
Commission and Sonoma Water announced that they have entered
into a planning agreement to explore pathways to relicense the
Potter Valley Project in the wake of Pacific Gas and Electric’s
decision to withdraw from the Federal Energy Regulatory
Commission relicensing process for the project.
Dig out that umbrella, and even the tire chains. It’s mid-May,
but a series of rare, winter-like storms will soak the Bay Area
and much of California through next week and bring up to 2 feet
of new snow to the Sierra Nevada.
The Los Angeles Department of Water and Power has turned two
big lakes into a monster battery capable of storing enough
energy to power tens of thousands of homes. It involves using
the excess wind and solar power L.A.’s renewable energy sites
produce during the day to pump water from Castaic Lake uphill
7.5 miles to Pyramid Lake.
In Ukiah Thursday, at least two dozen people who depend on the
Potter Valley Project for their farming operations gathered at
the Redwood Empire Fairgrounds to hear an update on the
facility’s future. “New information to come shortly, and a lot
of work still to do,” said Janet Pauli, chairwoman of the
Mendocino County Inland Water and Power Commission, a Joint
Powers Authority that is exploring the possibility of acquiring
the facility that Pacific Gas and Electric owns, but has
essentially abandoned.
Up a remote canyon in the towering eastern Sierra, a Southern
California company has an ambitious plan to dam the area’s
cold, rushing waters and build one of the state’s first big
hydroelectric facilities in decades. The project, southeast of
Yosemite near the town of Bishop (Inyo County), faces long
regulatory odds as well as daunting costs. But residents of the
Owens Valley downstream and state environmentalists are not
taking it lightly.
Counter-intuitively, the same environmental groups that have
championed the state’s climate goals want to kill all pumped
storage instead of evaluating each project on its own merits.
… Come hell or high water, there is no way that we can get to
100% renewable resources, which, by nature, are intermittent
and unreliable, without adequate storage.
The plan by PG&E Corp. comes after the bankrupt utility
said a transmission line that snapped in windy weather probably
started last year’s Camp Fire, the deadliest in state history.
While the plan may end one problem, it creates another as
Californians seek ways to deal with what some fear could be
days and days of blackouts.
Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.
Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.
Only 37 percent of the world’s longest rivers remain unimpeded
and free-flowing from their source to where they empty,
according to a study published today in Nature. Free-flowing
rivers are ecologically crucial — replenishing groundwater,
bolstering biodiversity, and reducing the impacts of droughts
and floods.
When California embarked on its quest to reduce emissions of
carbon dioxide and other greenhouse gases as a global model to
stave off climate change, its first target was the state’s
electric power industry. … But for purely political reasons,
the list omitted two power sources that are both free of
greenhouse gases and renewable: large hydroelectric dams and
nuclear plants.
The Ukiah City Council recently approved contributing another
$50,000 to a local group’s effort to explore the possibility of
buying the Potter Valley Project. … Sean White, the city’s
director of water resources, described the dam facility as
“essentially a diversion of Eel River water through a tunnel
that provides major benefits to Lake Mendocino, which provides
a significant amount of our water supply.”
Removal of the century-old dam is being watched closely around
the country as a potential model… In 2016, the first year
after it was removed, researchers found that no steelhead trout
swam past its former site to a tagging location seven miles
upriver. … So far this year, 123 steelhead have traveled
upriver.
A review of 170 years of water-related successes in California
suggests that most successes can be traced directly to past
mistakes. California’s highly variable climate has made it a
crucible for innovations in water technology and policy.
Failing power lines and crumbling roads are just some of the
major issues highlighted in the American Society of Civil
Engineers’ 2019 report card. It’s an analysis that comes out
every six years, grading 17 different areas of infrastructure
including waterways, aviation and schools.
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.
Ted Kennedy sums up what he sees along the river in the Grand
Canyon: “It’s buggy out there.” That is to say, an experiment
to change the flow of water from a dam near the Arizona-Utah
state line appeared to boost the number of aquatic insects that
fish in the Colorado River eat. Scientists are hoping to better
understand those results with a second bug flow experiment that
started this month and will run through August.
At first blush, Gov. Gavin Newsom’s latest action on water
seems fanciful and naive. But it has logic and conceivably
could work. Newsom wants to reexamine practically everything
the state has been working on — meaning what former Gov. Jerry
Brown was doing — and piece together a grand plan for
California’s future that can draw the support of longtime water
warriors.
The $800 million Swan Lake North Pumped Storage Hydroelectric
Project, 11 miles north of Klamath Falls, would move water
between two 60-plus-acre reservoirs separated by more than
1,600 vertical feet, pumping the water uphill when energy is
available and sending it downhill through generating turbines
when energy is needed.
Some lawyers say the Drought Contingency Plan, or DCP, may be
built on shaky legal ground and could be vulnerable to
litigation — depending on how the Bureau of Reclamation
implements it. One California water district has already sued
to block it.
The Don Pedro hydropower project, just west of Yosemite
National Park, has been churning out carbon-free electricity
for nearly a century. … None of the electricity is counted
toward California’s push for more renewable energy on its power
grid. A new bill advanced by state lawmakers last week would
change that — and it’s being opposed by environmental groups,
who say it would undermine the state’s landmark clean energy
law by limiting the need to build solar farms and wind
turbines.
This research will supply information needed for the U.S. Army
Corps of Engineers to update the 1970’s-era water control
manuals, which dictate the storm-season operations of both
reservoirs. Yuba Water’s goal is to have a new 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.
California is a wonderful place to study water. So many
interesting and important problems, thoughtful and insightful
authors, and much to be learned. Here is a selection of
readings (updated from a 2012 post) on California water.
A trio of federal wildlife management agencies said Friday that
listing the Northern California summer-run steelhead on the
Endangered Species Act may be warranted, but said more public
input is needed before a final determination is made.
The Department of Water Resources issued notice that it will
seek an updated environmental permit to operate the State Water
Project through a state-based approach in partnership with the
California Department of Fish and Wildlife. … Historically,
DWR has received environmental coverage for its pumping
operations through environmental parameters issued by the U.S.
Fish and Wildlife Service and National Marine Fisheries
Service.
Here’s what we know. The lower Klamath dams and reservoirs do
not provide multipurpose water storage, flood protection, or
irreplaceable energy. What they do provide are major barriers
to fish migration, toxic blue-green algae and fish disease (C.
shasta). The dwindling fish populations are proof. We must move
forward with removing the dams and restoring the Klamath to the
free-flowing river it once was.
The U.S. Court of Appeals for the 5th Circuit ruled on Friday
that the EPA’s 2015 power plant wastewater pollution rule was
not stringent enough, siding with environmentalists. Circuit
Judge Stuart Kyle Duncan ruled in favor of various
environmental groups that portions of the wastewater rule
regulating legacy wastewater and liquid from impoundments were
“unlawful.”
The area manager of the Shasta Dam, Don Bader said the image is
not a hole in the dam, but a spall, which is a small fragment
or a chip, that has broken off of a larger solid body.
Casey Hashimoto, general manager of the Turlock Irrigation
District since 2010, announced Tuesday that he will retire at
the end of 2019. The leader of one of Stanislaus County’s
largest water and power providers disclosed his plans at the
morning board meeting. Hashimoto, an electrical engineer,
joined TID in 1985 and was an assistant GM for 10 years.
A bill that would authorize the federal government to enact a
drought plan for Colorado River basin states in times of
shortage has passed Congress and is on its way to the White
House for the president’s signature. … Its aim is to
protect water users from deep losses and keep the
reservoirs and river healthy.
PG&E’s announcement it would no longer seek a new license
to operate the complex set FERC’s “orphan project” process in
motion… Prospective licensees have until July 1 to file
applications with FERC. … A new licensee must be able to pay
for the continued maintenance and operation of all project
facilities and be capable of monitoring and complying with
regulatory requirements arising from the project’s impacts.
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
engineers who worked on the project.
Whitewater rafting businesses are holding out hope of getting a
safe landing area near the Ward’s Ferry bridge over the
Tuolumne River, as a condition of relicensing the Don Pedro
hydroelectric project. At a Federal Energy Regulatory
Commission hearing Tuesday in Modesto, speakers said an
existing takeout for rafts on the Tuolumne, upstream from Don
Pedro Reservoir, is under water because of dam operations. And
the options for getting boats out of the water are not safe.
What image comes to mind when you think of Lake Mead? For most,
it’s likely the infamous “bathtub ring,” a troubling sign of
the depleted water supply in this life-sustaining reservoir.
But while this is one of the most frequently deployed images
associated with the decades long “drought” in the West, do we
really see it? Does it make an impact that’s strong enough to
shift our perceptions and motivate us to alter our personal
water consumption?
In the coming days, Congress will begin committee hearings on
unusually concise, 139-word legislation that would allow the
secretary of the interior to implement the Colorado River
Drought Contingency Plan, or DCP. … This agreement marks a
watershed moment in building our country’s resilience to
climate change.
To better understand how vineyard and housing development could
affect its Upvalley water sources, the city of Napa may join
forces with the county on a study of runoff and inflow into
Lake Hennessey and Milliken Reservoir.
Dozens of computer coding teams from around San Joaquin County
were tasked to create an app in roughly seven hours. The issue:
following the destruction caused by the malfunction of the
Oroville Dam in February 2017 and the evacuation of more than
180,000 people, could there be an app that can track dam
leakage, seismic activity and other structural impacts and
communicate with the appropriate individuals to help deter
another disaster?
A state environmental group is calling for the removal of an
old dam on the Eel River, contending it threatens the future of
protected salmon and steelhead while acknowledging it is a key
part of the North Bay’s water supply. Scott Dam, a 138-foot
concrete dam erected in 1922, is one of five aging dams
California Trout asserts are “ripe for removal” to benefit
their natural surroundings and communities.
It may be a unique situation when a dam removal might mean more
water for farmers instead of less, but the Klamath Basin is a
unique place. A report released last summer by the Bureau of
Reclamation (BOR) is leading more and more Basin farmers and
ranchers to believe that dam removal may have something big to
offer.
Firing live fish through the air may be rich fodder for
late-night television, but there are a surprising number of
situations where salmon and other fish sluice through tubes.
Still unconvinced Klamath River dam removal wouldn’t result in
excessive silt at Crescent City Harbor, Del Norte County
supervisors are asking the nonprofit organization behind the
effort to set aside mitigation dollars. With a 4-1 vote
Tuesday, the Board of Supervisors directed Community
Development Director Heidi Kunstal to draft a letter to the
Klamath River Renewal Corporation with its request.
It won’t arrive in time for this wet winter, but hopes are
rising that Central Valley politicians will soon deliver on one
of their top political goals in recent years: investment in
California water storage. Bills introduced last week by
Bakersfield Republicans in Sacramento and Washington, D.C.,
would redirect money from the state’s high-speed rail project
toward a series of reservoir projects, as well as repairs to a
canal serving Kern County farmers.
A system that transfers and diverts water from the Eel River
basin has been in Pacific Gas and Electric’s control for over
35 years, but the utility’s bankruptcy filing in January —
coupled with its interest in either selling or abandoning the
project — has Humboldt County officials intent on closely
following what happens next.
Oregon’s dam safety regulations are getting an overhaul, for
the first time in nearly a century. A bill pending in the
Legislature would rewrite the laws governing construction,
inspections and enforcement authority for hundreds of
state-regulated dams. The bill would increase the state’s power
to force owners of aging, dangerous dams to do maintenance and
make repairs. And it would require state approval and oversight
of all new dam construction and removal of old dams.
Plenty of snow in the Sierra and lots of rain just about
everywhere else in California have helped alleviate drought
conditions across the state. But there’s also another positive
byproduct of the wet winter — a likely boost in the amount of
hydroelectricity in California’s energy mix.
Bills introduced last week by Bakersfield Republicans in
Sacramento and Washington, D.C., would redirect money from the
state’s high-speed rail project toward reservoir projects, as
well as repairs to Friant-Kern Canal. … The proposals by U.S.
Rep. Kevin McCarthy and state Assemblyman Vince Fong seize upon
a common frustration among many valley Republicans that
billions of state and federal dollars dedicated to high-speed
rail would be better spent on capturing water from wet years…
Millions of Californians could end up with higher water bills
after the Trump administration on Friday announced that federal
emergency officials aren’t going to reimburse the state for
$306 million in repairs to Oroville Dam stemming from the 2017
spillway crisis. The Federal Emergency Management Agency said
federal taxpayers shouldn’t have to pay for problems that
existed prior to a massive hole forming in the dam’s concrete
spillway in February 2017…
Henry Ford said, “Failure is simply the opportunity to begin
again, this time more intelligently.” Rules enacted a decade
ago that were intended to protect California’s iconic salmon
and Delta smelt populations aren’t working and federal agencies
are now in the process of modernizing them, this time using
much better science.
Congressman Kevin McCarthy introduced legislation
Thursday to repurpose federal funding for the high-speed rail
project. The Repurposing Assets to Increase Long-term Water
Availability and Yield (RAILWAY) Act would take funding from
the high-speed rail project and use it for water infrastructure
projects in California and the West… McCarthy’s proposed
legislation is cosponsored by every Republican member of the
California Congressional Delegation.
The Federal Emergency Management Agency approved $205 million
to reimburse California for the Oroville Dam spillway
reconstruction costs, the state Department of Water Resources
announced Thursday. … However, FEMA has notified DWR that it
doesn’t think some of the reconstruction costs are eligible for
reimbursement,
The moment a lone duck was sucked into a 200ft-deep drain at a
reservoir in northern California – and reportedly survived –
has been captured on video. Known locally as the “Glory Hole”,
the giant spillway is designed to capture excess water at Lake
Berryessa reservoir in Napa County. Rick Fowler, the lake’s
water resources manager, filmed the bird as it drifted towards
the fast-swirling vortex and dropped down into the hole.
Deadly severe wildfires in California have scientists
scrutinizing the underlying factors that could influence future
extreme events. Using climate simulations and paleoclimate data
dating back to the 16th century, a recent study looks closely
at long-term upper-level wind and related moisture patterns to
find clues.
Water is starting to seep down the rebuilt Oroville Dam
spillway. California Department of Water Resources officials
said Wednesday this is common and will not affect the operation
of the dam’s gates, which are not watertight. … Both
spillways at the 770-foot earthen dam, the nation’s tallest,
collapsed in February 2017, forcing nearly 200,000 people
downstream to evacuate.
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. …
Dam by dam, owners of smaller hydroelectric projects around the
West look at them with a cold eye as relicensing looms. Created
with optimism a century ago, dams are now seen as fish-killers
and river-distorters. New energy sources are getting cheaper.
After decades of operation, owners approach relicensing knowing
that, if they are to continue generating a single watt of
electricity, they must fix the problems.
The state Department of Water Resources announced that releases
from the powerplant were being increased from 1,750 cubic feet
per second to 5,000 cfs. Ten-day projections show the lake
reaching 835 feet on March 14, according to DWR. The department
has said it does not anticipate that it will utilize the
rebuilt Oroville Dam spillway anytime soon; however, crews have
been making preparations in case its use becomes necessary. The
spillway becomes usable once water reaches its gates at 813
feet, which should happen Tuesday morning.
It’s a treasure that is all too easy for Palo Alto to take for
granted — an abundant supply of pristine water that flows from
the Sierra Nevada snowpacks and passes through the Hetch Hetchy
system before splashing out of local showers and faucets. Palo
Alto is one of 25 cities that belong to the Bay Area Water
Supply and Conservation Agency (BAWSCA), which manages the
member cities’ supply agreement with the San Francisco Public
Utilities Commission. … Even so, the cities don’t always know
which projects they’re helping to fund.
This tour explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs is the focus of this tour.

Funding awarded for the new Temperance Flat Dam may have fallen
short, but hopes for construction are still very much alive.
Jason Phillips, Director of Friant Water Authority and alumni
of the San Joaquin Valley Water Infrastructure Authority, has
insight as to why those involved with the project are still
optimistic.
It has occurred to me that the rush to remove the dams on the
Klamath River is lacking in a whole host of ways, and I commend
city Councilman Jason Greenough for being at least open to the
notion that the dam removal might not be in the best interests
of the community.
The water gushed from a valve near the base of the Loveland
Reservoir’s dam at 146,300 gallons per minute, cascading into
the Sweetwater River below. The impressive sight near Alpine
… marked the start of an ongoing transfer of water from the
Loveland Reservoir to the Sweetwater Reservoir, where the water
will be treated by the Sweetwater Authority and later supplied
to the water agency’s customers in National City, Chula Vista
and Bonita.
