The Sacramento Valley, the northern part of the Central Valley,
spreads through 10 counties north of the Sacramento–San Joaquin
River Delta (Delta). Sacramento is an important agricultural
region, growing citrus, nuts and rice among many other crops.
Water flows from the Sierra Nevada Mountain Range to the region’s
two major rivers — the Sacramento and American – and west into
the Delta. Other rivers include the Cosumnes, which is the
largest free-flowing river in the Central Valley, the lower
Feather, Bear and Yuba.
The Sacramento Valley attracts more than 2 million ducks and
geese each winter to its seasonal marshes along the Pacific
Flyway. Species include northern pintails, snow geese, tundra
swans, sandhill cranes, mallards, grebes, peregrine falcons,
heron, egrets, and hawks.
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.
Rather than physically move water hundreds of kilometers across
earthquake country between Northern California and San
Bernardino, the plan involves reallocating water virtually,
just as you would electronically transfer funds from one bank
account to another. Once the Chino Basin Program is
operational, in times of drought the southern region can draw
water from the new reserve instead of from the State Water
Project… That will mean water impounded by Oroville Dam can
be released into the Feather River, benefitting endangered
chinook.
Back in 2016, California Water Service Co. took two of its
groundwater wells in Chico out of service after tests showed
they were contaminated with toxic flourinated chemicals known
as PFAS—or per- and polyfluoralkyl substances—that have been
linked to cancer and other adverse health effects. The move was
done quietly.
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.
Reliable water is critical to every aspect of the economy as
more than 40 percent of the nation’s fruits, nuts and
vegetables are grown in the Central Valley, much of that using
water from the Central Valley Project (CVP) and its largest
reservoir — Shasta Lake.
Water in the vault will go the Regional Wastewater Treatment
Plant in Elk Grove. This new system is designed to stop
flooding on East Sacramento streets.
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.
In the forecast stretching from Tuesday through Friday are
plummeting temperatures, hurricane-force gusts that could reach
or exceed 100 mph in some locations, giant waves of up to 37
feet, as much as four feet of snow in the Sierra Nevada and
heavy rain in lower elevations between San Diego and Salem.
With winter rains on their way, officials worry a dam that
creates a small lake 17 miles west of Redding could collapse,
inundating downstream homes with up to 20 feet of water if
sediment and debris clogging two outlet pipes is not cleared.
Two 30-inch outlet pipes at Misselbeck Dam have been clogged
with silt and debris since last summer, forcing water from
Rainbow Lake to flow over the top of a deteriorated
100-year-old spillway…
The annual opening of the hatchery’s ladder provides a window
into the wonders of science, but also shows the key role the
hatchery system plays in keeping California’s salmon fishery
healthy.
Work on the Rio Vista Side Channel Habitat Project in Red Bluff
has been completed, marking another milestone for the Upper
Sacramento River Anadromous Fish Habitat Restoration Program,
with immediate results observed… Within one week of opening
the side channel, endangered winter‐run Chinook juveniles were
observed making use of it.
The American Society of Civil Engineers has recognized the
Oroville Dam rebuild as one of 10 outstanding civil engineering
projects. Two runners-up and a winner will be chosen at the
2020 Outstanding Civil Engineering Achievement gala in
Washington D.C. on March 13.
On Thursday (11/21) we may find out whether the California
Department of Water Resources (DWR) is proposing operations of
the State Water Project that are significantly more protective
than the Trump Administration’s biological opinions, or whether
DWR will be aligning with the Trump Administration.
The Sacramento-San Joaquin Delta is hitched to so many things.
Our estuary is a critical habitat for fish and wildlife, home
to millions of people, and the hub of our state’s water
delivery system. From the Sierra Nevada to the mouth of the San
Francisco Bay, what happens in one part of the Delta watershed
affects the entire estuary.
The extra 90 cubic feet per second are designed, in part, to
attract salmon up the creek – and the flows start a little
later than in recent years due to the failure of state
Department of Fish and Wildlife pumps in the Yolo Bypass. Rich
Marovich, streamkeeper for the Solano County Water Agency
and Lower Putah Creek Coordinating Committee, said because
it has been so dry this fall, the later release may be
beneficial.
City Council members – sitting as the directors of the
Vacaville Groundwater Sustainability Agency – approved a
collaboration agreement Tuesday with the other sustainability
agencies in the Solano Subbasin in order to keep the
groundwater grant funding flowing.
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.
The district’s decades-long election drought occurred as a
result of an insufficient number of candidates to require
elections. … Changes in the district’s operations led to a
greater number of candidates for the recent election. The
district’s biggest issue is implementing the Sustainable
Groundwater Management Act …
This fall run, while late, is about average in terms of the
number of fish coming up the river. And, in terms of their
condition, Crawshaw said the fish are “very healthy” and “good
sizes.”
Ponds at wastewater treatment plants are like magnets for birds
and bird-watchers, especially those along the migration flyway
in California’s Central Valley area. Among them is the Clear
Creek plant in Redding, along the Sacramento River, which
serves as its receiving stream.
The nation’s largest water agency signed an agreement that
legally bars it from participating in a controversial plan to
raise Shasta Dam, a move applauded by environmental groups that
fiercely opposed the proposal out of fears enlarging the
state’s biggest reservoir would swamp a stretch of a protected
Northern California river and flood sites sacred to a Native
American tribe.
Woodland city officials are continuing to build the case for
Cache Creek flood control, recently approving $900,000 for
another study that could be yet another downpayment on a
multi-million dollar project ultimately paid for by federal,
state and local governments.
On a secluded corner of Marywood Drive in Paradise sit two
vacant lots, side by side. The empty space used to hold
single-family residences surrounded by Ponderosa pines. That
was until the November 2018 Camp Fire — California’s deadliest
and most destructive wildfire — leveled the Butte County town
and destroyed more than 13,000 homes. Now, one year later,
these lots are being rebuilt by two Paradise natives, Christine
and Dave Williams, who bought the properties after the fire.
A little-known, local water district – the Omochumne-Hartnell
Water District – will hold their first board member election in
43 years on Nov. 5. … The district was established in 1953,
mainly to help supply surface water off the Cosumnes River to
the landowners in this area.
On a cool and misty morning somewhere south of Redding,
California, jet boats roar across the tranquil Sacramento
River. Armed with tridents, machetes and poleaxes, it seems
akin to a scene from an action movie; except that “California
Department of Fish and Wildlife” is painted on the boats.
Solano County has filed requests for water and sewer hookups at
the Brown Street location of the proposed Tiny Shelter homeless
pilot project – services that will cost the county thousands of
dollars to reconnect the property to Vacaville’s main lines.
Last year, the worst wildfire in California history nearly
leveled a town called Paradise. Since then, residents have
scattered and a lawsuit simmers. Can recovery efforts ever
return a community to its old self?
The California Water Service Co. may have just shot itself in
the foot, with tens of thousands of residents in Paradise,
Chico and northwestern Butte County as collateral damage.
Jim Brobeck, water policy analyst for AquAlliance, said the
Agricultural Groundwater Users of Butte County may not have the
public’s best interests in mind. The priority of farmers,
Brobeck said, is to make sure they have water in their wells,
not to protect the shallowest portion of an aquifer. Water
purveyors, he said, like to “exercise” aquifers and may well do
so to the point where the public suffers.
The state Department of Water Resources and Butte County
announced the settlement Tuesday, more than two years after
spillways at the Oroville Dam crumbled and fell away during
heavy rains. The repairs resulted in heavy truck traffic that
damaged Butte County roads. Butte County sued in August 2018.
A bacteria outbreak at a state prison in Stockton has cost
California $8.5 million and doesn’t appear to be going away
seven months after it infected two inmates, one of whom died.
A provider of drinking water in Sacramento County is seeking
reimbursement from the U.S. Air Force for a filtration system
it installed to take contaminants out of groundwater near the
former Mather Air Force Base.
A major fish restoration project is underway on private
property near Cottonwood. River Partners shared a video of new
side channels that are being built to help the recovery of
struggling wild salmon populations in the Sacramento River.
Sacramento Metro Fire has a new tool to assist in their
firefighter trainings, which also helps recycle millions of
gallons of water at the same time. The Pump Pod is a mobile
tank that assists in catching and recycling thousands of
gallons of water during firefighter training exercises.
To survive the next drought and meet
the looming demands of the state’s groundwater sustainability
law, California is going to have to put more water back in the
ground. But as other Western states have found, recharging
overpumped aquifers is no easy task.
Successfully recharging aquifers could bring multiple benefits
for farms and wildlife and help restore the vital interconnection
between groundwater and rivers or streams. As local areas around
California draft their groundwater sustainability plans, though,
landowners in the hardest hit regions of the state know they will
have to reduce pumping to address the chronic overdraft in which
millions of acre-feet more are withdrawn than are naturally
recharged.
Explore the Sacramento River and its tributaries through a scenic landscape as we learn 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 will get an on-site update of Oroville Dam spillway repairs.
Building on the Governor’s call to “position California to meet
broad water needs through the 21st Century” there are unique
opportunities in the Sacramento River Basin to more effectively
integrate 21st Century infrastructure into our multi-benefit
water management approaches to help achieve resiliency.
After morning services, Florin Ciuriuc joined the line of
worshipers waiting to fill their jugs with gallons of free
drinking water from a well on the property, a practice church
leaders had encouraged. Church leaders boasted it was the
cleanest water in Sacramento, according to Ciuriuc. In fact,
test results showed the water contained toxic chemicals from
firefighting foam used for decades on a now-shuttered Air Force
base a mile away.
A salmon habitat project will get underway Monday just outside
the city of Red Bluff. One of several such projects in the
North State, the Rio Vista Side Channel Habitat Project will
offer protection for juvenile salmonids, including endangered
winter-run Chinook…
Katie Fyhrie, a grower at Cloverleaf Farm in Davis, Calif.,
worries that the farm won’t be able to keep producing stone
fruits—which depend on the timing and duration of winter
chill—in the long-term. … With that in mind, Fyhrie and her
team have started growing elderberries.
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…
California isn’t in an official drought and under mandatory
water conservation, but climate change means that saving water
is always crucial. That’s why a recent announcement should not
go unnoticed: The Sacramento Regional County Sanitation
District won state approval to deliver recycled water to
agricultural and habitat conservation land in the southern part
of the county.
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.
By century’s end, Sacramento is expected to feel much like
Tucson or even Phoenix, Arizona, according to the state’s 2018
Climate Assessment for the Sacramento Valley. Daily
temperatures are projected to rise 10 F in the valley by 2100,
and the number of days topping 104 F are on track to increase
from four days a year to 40.
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.
If there is a hell for salmon, it probably looks like this.
There were many more golf balls in the water than salmon this
summer, whacked there by enthusiasts at Aqua Golf, a driving
range on the bank of the Sacramento River. Below the surface,
the gravel salmon need to make their nests had been mined
decades ago to build Shasta Dam, 602 feet tall and with no fish
passage. The dam cut off access to all of the cold mountain
waters where these fish used to spawn.
There are nut festivals. There are fruit and vegetable
festivals. Hot sauce and spicy food are cheered in other
places. There are wine and beer events. All are fun and bring
entertainment to our lives. But for all of that, there is
something extraordinary about Saturday’s Salmon Festival in
Oroville.
At the August meeting of the California Water Commission, Karla
Nemeth, Director of the Department of Water Resources (DWR),
spoke to the commissioners about the Department’s strategic
plan and the work underway on the Delta conveyance project,
which she noted nests into the strategic plan as a key feature
of what needs to be done to modernize the State Water Project.
Lawns cool the air, reduce urban heat-island effect, remove
pollutants, and provide play spaces. … From a design
standpoint, they make uncluttered views, provide background and
contrast for flowers, and create our outdoor living spaces.
Historically, lawns provided all those benefits at high cost,
literally and environmentally.
Trucking juvenile hatchery salmon downstream is often used in
the California Central Valley to reduce mortality during their
perilous swim to the ocean. But is it all good? Researchers …
published an article in Fisheries this month exploring the
history and implications of salmon trucking in a changing
climate.
A project to restore a portion of Brentwood’s Marsh Creek got a
big boost with a new $1.4 million U.S. Environmental Protection
Agency grant. … The Three Creeks Parkway Restoration project
aims to improve the creek’s floodplain, provide quality habitat
for Chinook salmon and Swainson’s Hawk as well as expand
recreational opportunities in the area.
All of September, crews have been dumping rocks into the bed of
the river to create an ideal habitat for salmon to spawn. Dams
along the American River cut off access to the salmon’s natural
breeding ground.
Before all those thousands of miles of levees went in, the
Central Valley had one of the West Coast’s largest salmon runs,
with a million or more of these mighty fish returning each
year. A big reason for the salmon’s suc-cess was that the
valley was among the most extensive floodplains in the world.
It appears that Woodland is now in the “advancement” stage with
the Army Corps of Engineers willing to work on a plan for
longterm flood protection along the city’s northeast side.
However, the effort could just as quickly be reversed,
according to members of the City Council, if they don’t get
farmers on board with their efforts.
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.
The law said schools had to test by July, but many schools
still hadn’t submitted the results by the deadline. As of
September 9, about a quarter of California schools now report
detectable levels of lead in school drinking water but it
appears many schools in our area still haven’t submitted the
results.
The Sacramento–San Joaquin Delta has more non-native species
than native ones, and its estuary is considered the most
invaded in the world. We talked to Jim Cloern—an emeritus
scientist with the US Geological Survey and an adjunct fellow
at the PPIC Water Policy Center—about this challenge.
Residents say the system is outdated because it combines 7.4
million gallons of sewage and storm water to be stored
underground, and they want a more modern system that splits the
two.
Something is amiss on Sherman Island, a whale-shaped swath of
farm and grazing land at the confluence of the Sacramento and
San Joaquin rivers. If you don’t know what ails the place, it
might be hard to pinpoint the problem.
Newsom saw SB 1 as a mortal threat to something he’s been
supporting since shortly before he took office: a tentative
truce in California’s longstanding water wars. The truce
revolves around the flow of water in and out of the Delta from
California’s most important river systems, the Sacramento and
San Joaquin.
Gov. Gavin Newsom plans to veto a bill passed by California
lawmakers that would have allowed the state to keep strict
Obama-era endangered species protections and water pumping
restrictions for the Sacramento-San Joaquin Delta. Newsom’s
intentions … comes less than 24 hours after state lawmakers
passed the sweeping legislation.
There’s no certain answer as to how the nutria population
re-emerged after being declared eradicated in California
decades ago but the population is spreading and causing serious
concern. The Department of Fish and Wildlife was recently
awarded $10 million to wipe out the large, invasive rodents and
that effort is now well underway.
Efforts to increase recycled water use in California got a
significant boost this week with the State Water Board’s
issuance of an order authorizing the Sacramento Regional County
Sanitation District’s program to deliver an average of 45
million gallons per day of recycled water from the Sacramento
Regional Wastewater Treatment Plant …
At the Association of California Water Agencies‘ spring
conference, a panel of lawyers covered the basics of the legal
framework for the Delta. The panel was billed as ‘All the
Acronyms You Need to Know”, but no 1.5 hour panel discussion
could possibly cover all that. However, the panel did a good
job of hitting the main ones and highlighting current issues.
Tiscornia Beach, an area on the lower American River frequented
by summer visitors, tested 7.5 times higher than the safety
threshold on Tuesday, according to data from the county and the
Central Valley Regional Water Quality Control Board. Samples of
river water taken two weeks earlier at nearby Discovery Park
tested almost 5.5 times higher than the safety threshold.
A popular Elk Grove neighborhood destination has tested
positive for the toxic blue-green algae that fatally sickened
dogs across the country this summer.
The western pond turtle in Butte County is currently shaking in
its shell, due to habitat alteration and introduced species
that are killing off the local reptile. … The turtle is being
evaluated for listing as threatened or endangered, according to
California Department of Fish and Wildlife officials.
A Sacramento Bee investigation found high levels of E. coli
bacteria — a sign of fecal contamination — along the lower
stretch of the American, where homeless camps line the banks,
residents walk their dogs, and where thousands of swimmers dip
into the water to escape Sacramento’s summer heat.
The deadliest and most destructive
wildfire in California history had a severe impact on the water
system in the town of Paradise. Participants on our Oct. 2-4
Northern California
Tour will hear from Kevin Phillips, general manager of
Paradise Irrigation District, on the scope of the damages, the
obstacles to recovery and the future of the water district.
The Camp Fire destroyed 90 percent of the structures in Paradise,
and 90 percent of the irrigation district’s ratepayer base. The
fire did not destroy the irrigation district’s water storage or
treatment facilities, but it did melt plastic pipes, releasing
contaminants into parts of the system and prompting do-not-drink
advisories to water customers.
The Bureau of Reclamation, in coordination with the California
Department of Water Resources, today announced its decision to
move forward with a restoration project to improve fish passage
and increase floodplain fisheries-rearing habitat in the Yolo
Bypass.
A major groundwater sustainability study was approved by the
Butte County Board of Supervisors which will look at different
aspects into future water allocations and conservation in Butte
County, including the possibility of building a pipeline from
Paradise to Chico.
Residential graywater offers up a huge potential for our city
to offset potable water use. When the next drought rolls
around, and it will, we could be sitting pretty with healthy
trees and landscapes using less water from the Sierra than we
do now.
When the next drought rolls around, and it will, we could be
sitting pretty with healthy trees and landscapes using less
water from the Sierra than we do now. How could we accomplish
this? The answer is graywater, defined in California as the
discharge from laundry wash water, showers, and bathroom sinks.
Of all the chicken-or-the-egg dilemmas that will determine
Paradise’s recovery from the Camp Fire, water may be the most
critical. To rebuild, the town needs water from the Paradise
Irrigation District. To survive, PID needs the town to rebuild.
One can’t happen without the other, and it’s been tough to
figure out how it’s going to work.
When the salmon are healthy, the world is healthy. That means
the waters are clean and fast-running and the bottom gravel is
clean. It means the rivers … are pouring as they should into
our oceans, bringing nutrients and sediments into the salt- and
fresh-water interplay.
If you see something hopping around in Big Chico Creek, chances
are it could be the foothill yellow-legged frog. This frog is
currently being evaluated by the California Department of Fish
and Wildlife to possibly be placed on the state’s endangered
species list.
Recently, the Sacramento Press Club hosted a panel discussion
on the future of California water featuring Secretary Wade
Crowfoot, Metropolitan General Manager Jeff Kightlinger, and
State Water Contractors General Manager Jennifer Pierre.
A 10-acre island in Isleton, an hour south of Sacramento in the
California Delta’s fresh-water Seven Mile Slough, is changing
hands for $1.195 million. (SF’s median condo price is about
$1.25 million.) The buyer is Thai Tran, who owns a mini-chain
of Vietnamese pho restaurants in Sacramento, and listing agent
Tony Wood of KW Commercial says Tran and his family plan to
transform the property into a destination.
DWR is currently overseeing five habitat restoration projects
in Suisun Marsh. In October 2019, one of these projects, the
Tule Red Tidal Habitat Restoration Project – which converts
approximately 600 acres of existing managed wetland into tidal
habitat – is expected to finish construction.
An idea to pipe water from Paradise to Chico took its first
step Wednesday, when the Paradise Irrigation District board
signed off on a feasibility study for the proposal. The plan
might seem far-fetched at first glance, but it would solve a
couple of problems.
The Colusa and Glenn groundwater authorities will host a pair
of public workshops about local groundwater conditions and
areas of concern in portions of Glenn and Colusa counties…
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.
Get an up-close look at some of
California’s key water reservoirs and learn about farming
operations, salmon habitat restoration, flood management and
wetlands on our Northern California Water Tour Oct. 2-4.
Each year, participants on the tour enjoy three days exploring
the Sacramento Valley during the temperate fall. Join us as we
travel through a scenic landscape along the Sacramento and
Feather rivers to learn about issues associated with storing
and delivering the state’s water supply.
Woodland is sitting atop what is essentially an underground
reservoir containing millions of gallons of freshwater. And for
much of the past three years, the city has been banking excess
water during the winter months to use during the summer when it
isn’t allowed to make withdrawals from the Sacramento River.
The small channel island near Brannan Island can be found about
one hour south of Sacramento in the Delta’s fresh-water Seven
Mile Slough, in Sacramento County. The marina and resort have
been in operation for more than 60 years.
Senate Bill 1 is seen as a pre-emptive strike by California
lawmakers before the Trump administration ushers in new
biological opinions to alter water deliveries through the
Sacramento-San Joaquin Delta.
A proposal by the California Department of General Services to
remove the fountain at the head of Capitol Mall has distressed
preservationists, who say it is a historic icon that should
remain.
A state court of appeal has upheld a Shasta County Superior
Court decision to stop a Fresno-based water district from doing
an analysis of the effects of raising the height of Shasta Dam.
The Westlands Water District had asked the California Third
District Court of Appeal to overturn the lower court’s
preliminary injunction that ordered the district to stop work
on an environmental impact report.
Last week, the Delta Stewardship Council held a public hearing
to review proposed changes to how spending decisions on the
maintenance of Delta levees are made, and the plan — known as
the Delta Levee Investment Strategy — has drawn criticism from
several sources.
The Department of Water Resources is continuing to work on the
environmental planning and permitting to modernize State Water
Project infrastructure in the Delta. This effort is consistent
with Governor Newsom’s direction and support for a
single-tunnel project to ensure a climate resilient water
system.
Managing a river is no easy feat. Consider the needs for water
released at Shasta Dam into the Sacramento River: salmon need
cold water, sturgeon need warm water, and irrigators just need
water. Recent research shows that all three needs can be met in
all but the most drought-stricken years. How?
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.
Commercial salmon catches have surpassed official preseason
forecasts by about 50%, said Kandice Morgenstern, a marine
scientist with the California Department of Fish and Wildlife.
Harvests have been particularly strong in Morro Bay, Monterey
and San Francisco, but weaker along California’s northern
coast.
A panel of experts discuss how reactivating the floodplains can
provide habitat and food for native fish and for migrating
birds, and highlights the many projects and opportunities in
the Sacramento Valley.
Outside the walls of the lab lies an environment increasingly
unfit for fish like delta smelt. The Sacramento-San Joaquin
Delta, some 40 miles inland from the San Francisco Bay, is a
1,100-square-mile tidal marsh that for millennia teemed with
salmon, shellfish, tule elk, deer, and waterfowl — all of which
supported a Native American population of about 300,000 people.
The plan affecting Sacramento River tributaries has not been
released, but water-resource managers in the region said they
have been collaborating with government agencies and
environmental groups to develop voluntary agreements that would
accomplish the goals of the state board’s flows-only
methodology.
In a paper published Tuesday in the Journal of Applied Ecology,
scientists at the University of California, Santa Cruz and the
National Marine Fisheries Service used statistical modeling to
determine an optimal water management plan that would protect
both species and ensure other water users would benefit as
well.
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.
Butte County, California Water Service and Paradise Irrigation
District are kicking off the lengthy process on a project to
pipe water from Paradise to Chico. The project would seek to
restore some viability to PID, which lost most of its customers
after the Camp Fire. It would also reduce demands on the
groundwater basin currently used for water in Chico to boost
long-term sustainability.
The Delta smelt is practically extinct in the wild already. So
could the Delta be repopulated by taking up the farmers’ offer
to “hatch and repopulate the fish,” as Jack Fowler says in
National Review? That certainly sounds like common sense!
Except that the Delta smelt war has never really been about the
Delta smelt at all.
The Sacramento-San Joaquin Delta has been extensively studied
in terms of its biology, chemistry, and physics, but this
wealth of data leaves out a crucial piece of the puzzle:
people.
Steven and Cindy Bolt couldn’t have been happier. For the first
time since February of 2017 and the Oroville Dam spillway
crisis they could launch their houseboat from the spillway’s
boat ramp. “It’s been our favorite place to come,” said Cindy.
“And it’s been a long time.”
The Sacramento County Water Agency says customers have alerted
the agency to the scheme, in which the caller claims county
officials will shut off their water within 30 minutes if they
don’t make a payment, the county Department of Water Resources
said Tuesday in a news release.
Local land owners have an opportunity to get their irrigation
systems inspected free of charge as part of a program offered
across Northern California. Jay Thomas, engineering technician
for the Irrigation Training Facility at California State
University, Chico, said this program is part of a mobile
irrigation laboratory that services the growers of Northern
California.
A Butte County project will expand its partnership with Chico
State and Stanford University to analyze available groundwater
systems. … It’s a groundbreaking project for water management
in the county, according to Paul Gosselin, director of the
county’s water and resource management department.
A Butte County project will expand its partnership with Chico
State and Stanford University to analyze available groundwater
systems. The project involves analysis of well logs, and hopes
to expand the analysis using magnetics and a grid to fill in
holes in the data.
San Joaquin County has filed a lawsuit in Superior Court asking
the state Department of Water Resources to abide by local
drilling permit requirements to protect wildlife and water
quality in accordance with California law.
Opponents of the twin tunnels breathed a collective sigh of
relief in April when Gov. Gavin Newsom put a formal end to the
California WaterFix project, but that action also called for
the assessment of a single-tunnel project in the Delta. The
first major step in that direction took place last week when
the Department of Water Resources (DWR) initiated a series of
negotiations with public water agencies that participate in the
State Water Project (SWP)…
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.
The five-year project will clear sedimentation and vegetation
to restore flow capacity of a four-mile stretch of the
state-maintained Elder Creek in Tehama County. With a goal of
clearing approximately one mile per year, the project reduces
flood risk for the nearby town of Gerber and surrounding
farmland, which includes fruit and nut orchards.
The Westlands Water District, which provides irrigation water
to farmers on the west side of the San Joaquin Valley, was
working on a report assessing the environmental impacts of
raising the height of the dam. But a judge ruled Wednesday that
Westlands’ work violated a state law that prohibited local and
state agencies from participating in any projects that would
have an adverse impact on the McCloud River.
Sutter County has been ordered to reduce arsenic levels in its
drinking water or face some steep penalties from the
Environmental Protection Agency. … If the county doesn’t
comply, it could be fined more than $32,000 for each violation.
California’s biggest river—the Sacramento—needs a lot of room
to spread in big water years. A floodplain project called the
Yolo Bypass allows it to flood naturally, while also providing
habitat for waterbirds, fish, and other aquatic species. We
talked to Ted Sommer, lead scientist for the Department of
Water Resources (DWR), about this versatile landscape.
Sacramento remains one of the two most flood-prone cities in
the nation along with New Orleans, according to experts. Now
the River City faces a new water threat: homeless people
setting up camp on—and digging into—the 1,100 miles of earthen
levees that Sacramento and surrounding areas count on to
protect them from devastation.
The center, being built at North Natomas Regional Park, will
feature the city’s first 50-meter competition pool with 13
diving boards and lanes. It will also feature a 25-meter pool,
four water slides, a shallow kids’ pool, and a kids’ rope
course and play area…
Pacific salmon that spawn in Western streams and rivers have
been struggling for decades to survive water diversions, dams
and logging. Now, global warming is pushing four important
populations in California, Oregon and Idaho toward extinction,
federal scientists warn in a new study.
Water is the lifeblood of the Sacramento Valley. Yet, the best
methods for storing and using the precious resource are often
elusive. A new water system in operation in Roseville treats
underground aquifers like a bank, making deposits in times of
surplus for withdrawal in times of drought.
The community wanted to create flood relief for the people of
Hamilton City; The Nature Conservancy wanted to find a way to
restore native habitat. Area farmers wanted to reduce damages
from flows that scoured their property along the edge of the
river. The Hamilton City Flood Damage Reduction and Ecosystem
Restoration project was able to address these problems with one
solution.
The Sacramento-San Joaquin Delta is arguably the most
extensively studied and monitored ecosystem in the world. This
has generated mountains of data on everything from the
locations of the smallest fish to the water quality conditions
of the largest reservoir. Knowing where to access the most
up-to-date information can be a real challenge, but fortunately
several online dashboards can help
The Coleman National Fish Hatchery is expecting good returns of
their fish in the foreseeable future after a few lean years of
comebacks. … Mother Nature worked with the hatchery this year
providing high water levels and spring storms, said Galyean.
When nature was not working in the hatchery’s favor was during
the recent drought.
For many years, federal “biological opinions” for delta smelt
and winter run chinook salmon have dictated restrictions on
operations of the pumps, reservoirs and canals of the federal
Central Valley Project and State Water Project… Informed by a
decade of science and on-the-ground experience with what we
know has not worked, long-awaited new federal biological
opinions are finally nearing completion.
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.
A judge has rejected a San Joaquin Valley irrigation district’s
request to move a lawsuit against raising the height of Shasta
Dam to Fresno County. Westlands Water District, based in
Fresno, wanted to move the lawsuit against it to its home
county, but a judge has ruled the case will remain in Shasta
County.
The project is a part of the restoration of salmon habitat
stemming from the Central Valley Improvement Act and will take
place on the left bank of the Sacramento River at the East Sand
Slough… It reconnects the East Sand Slough to the Sacramento
River during minimal flows by excavating the main channel and
entrances.
The Department of Water Resources has secured final state and
federal approval for a project that will expand a migration
corridor for fish to the Yolo Bypass, the Sacramento Valley’s
main floodplain. The project is part of the largest floodplain
restoration action on the West Coast…
The Solano County Planning Commission on Thursday was told that
a proposal to more stringently protect agricultural uses in the
Cache Slough area could negatively affect the goals of the
Delta Plan.
The initial objectives of the restoration project were to:
improve habitat for the Delta smelt, reduce saltwater
intrusion, reduce submerged aquatic weeds and reduce invasive
non-native fish species that feed on native fish. Carl Wilcox,
a CDFW policy advisor explained the objectives are now more
broad and include accommodations for recreational and economic
activities that are key to the region’s residents.
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.
Assembly member Jim Cooper, D-Elk Grove, authored AB 137, which
would prohibit people from altering the stability of levees or
bypasses, as well as prohibit people from living and camping on
the structures. The legislation would make it a misdemeanor
charge.
Faced with mounting opposition to its $315 million plan to
restore the tidal marshland on Franks Tract in the
Sacramento-San Joaquin Delta, the state has begun seeking input
from residents, boaters, fishermen and others on possible
alternatives.
Crews are digging and removing 66,000 yards of dirt to make
room for an underground vault. It will be used to catch
rainwater during a storm in order to alleviate flooding around
the park. Behind the fence, crews are hauling away dirt.
Workers will eventually put the 6 million-gallon water vault 22
feet underground.
On Monday the Glenn Groundwater Authority passed an operation
fee increase for water service, despite meeting some
opposition. Anyone within the Glenn County portion of the
Colusa subbasin except for Willows and Orland will have to pay
the fee. The board set the operation fee at $1.61 per acre, per
year for the fiscal 2019-2020 year.
New legislation authored by Assemblymember Jim Frazier,
D-Discovery Bay, and signed into law by Gov. Gavin Newsom,
calls for the development of a plan to deal with abandoned and
derelict commercial vessels in the Delta. A draft of that plan
is now available for review and public comment.
The standoff between Sacramento County and the California
Department of Water Resources over the Delta’s future took a
twist in June, moving from quiet canals and pear orchards along
the river to a courtroom in the central city. That’s where
county officials were granted a temporary restraining order
against DWR to halt what they call risky and illegal drilling.
In 2016 California’s rainy season kicked off right on schedule,
at the beginning of October. … By February there was so much
water filling Northern California’s rivers that Oroville Dam,
the tallest in the country, threatened to break after its
spillway and emergency spillways both failed. It was a wake-up
call. In just a few months California had gone from
five-year-drought to deluge, ending up with the second wettest
year on record for the state.
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 visitors call the “gem of Chico,” the local go-to
location for a quiet and relaxing day trip on the waterfront,
is infested with toxic algae, officials say. The Butte County
Public Health Department warned people on Monday to stay away
from Horseshoe Lake after colonies of microscopic cyanobacteria
grew out of control…
In their analyses, they write that the plan poses risks to
threatened fish; that the process is rushed; that they didn’t
receive enough information to provide a complete scientific
review; and that the Trump administration may be skewing the
science to make the environmental impact look less serious.
The Sacramento-San Joaquin Delta historically has been an
agricultural paradise. But sometimes there is a disconnect
between the agricultural community and the urban culture. A
fourth generation farmer has made it her mission to reconnect
the two in hopes of inspiring the next generation to consider
farming as a career.
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.
Nearly one in five California schools found detectable
levels of lead in the drinking water, according to recent data
from the State Water Board. … Monday was the deadline, under
a 2017 law, for local water districts to test school drinking
water for lead. CBS13 found there is still no testing data for
at least 100 schools in our area, but many local schools tested
well above the limit.
The Newsom Administration and the State Legislature approved a
commitment of $70 million in the 2019-2020 State Budget for a
comprehensive series of innovative fish and wildlife habitat
enhancement actions identified in the collaborative Bay-Delta
Voluntary Agreement proposals. This is a significant, early
investment in the success of the Voluntary Agreements.
The 2019 Water Summit will take place in a new location on the
Sacramento riverfront on Oct. 30, 2019. At this event,
attendees will have the opportunity to hear the latest
information on key issues affecting water in California and the
West from leading experts and top policymakers.
Delta smelt are poor swimmers. When they have to swim against
voluminous outflows, they struggle. They also lack endurance
for distance and swimming against currents. This was the result
of the taxpayer-funded swim performance test conducted more
than 20 years ago. Why is this important?
Although flooding hasn’t occurred in Clarksburg since the
construction of the levee system in the early 1900s, the
community is considered a moderate to high hazard flood area,
according to a county report. For that reason, a flood risk
reduction feasibility study has been prepared for the town
similar to those conducted for Yolo and Knights Landing with
funds from the California Department of Water Resources.
The Center for Biological Diversity and San Francisco Baykeeper
sued the Trump administration to force the addition of the
longfin smelt, the Sierra Nevada red fox and six other species
to the Endangered Species List… According to the lawsuit, the
agency had previously found the species worthy of endangered
species protections under the Obama administration but
the Trump administration had slow-walked the process…
There are more concerns over lake levels in Oroville as Butte
County leaders take initiative to explore alternative options
for safety measures. The Department of Water Resources (DWR), a
leg of the State Water Project, manages the Oroville Dam. On
Wednesday, DWR officials remained adamant in saying they have
no plans to release water from the Oroville Dam spillway.
Barbara Vlamis is smiling. Often, the executive director of the
Chico-based advocacy group AquAlliance wears a steely
expression, as her work involves David-versus-Goliath battles
against powerful interests—namely, government agencies and
water brokers. Now, she’s satisfied, even a bit celebratory.
The planned improvements include replacing six of the lake
pumps and three booster pumps with four new, higher-powered
pumps capable of pumping water directly to the treatment plant
without the use of booster pumps.
For years fisheries experts have watched the number of
winter-run Chinook salmon dwindle as they suffered through
drought and adverse conditions in the Sacramento River. But
this year a small crop of the endangered salmon have made their
way back from the ocean to return Battle Creek in southern
Shasta County, something that hasn’t happened in some 25 years.
And officials hope the fish are the beginning of a new run of
salmon in the creek.
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.
Five years ago, Deb Fallows and I made the first of what became
many visits to the farming town of Winters, California. …
When we first visited five years ago, the main question for the
area’s nut-tree farmers, and for California’s agricultural
economy as a whole, was whether the state’s drought-ravaged
water supplies could support such commercially valuable but
water-intensive crops.
The lawsuit against the Fresno-based Westlands Water District
was filed in Shasta County Superior Court on Monday. State
officials have for years maintained that raising the height of
the dam would violate the Wild and Scenic Rivers Act because a
higher dam would further inundate the McCloud River, in
violation of state law.
The 1,700-acre off-the-grid health retreat, where clothing is
optional in the pools, went up for sale quietly last year for
$10 million. Now, the property near Williams (Colusa County) is
officially listed with Sotheby’s International Real Estate.
In response to a story that aired Thursday night on CBS13, the
City of Sacramento is now responding and creating a task force
to combat a growing public safety concern. Homeless campers are
carving into levees that protect Sacramento from flooding, a
break in the levee could be devastating.
When people think of natural disasters in California, they
usually think of earthquakes, drought or wildfire. But the
worst disaster to ever hit the Golden State was the Great Flood
of 1862. When people of European descent first arrived in
California, the native people told them tales of great deluges
in which the rivers overran their banks and large areas of land
were inundated. The newcomers paid little heed to these
stories, and often settled in low-lying areas with easy access
to water sources.
Sometimes erosion can be caused by fallen trees or rodents, but
now they’re finding faults intentionally caused by homeless
people carving out campsites. … Tim Kerr, general manager for
the American River Flood Control District, said his engineers
find about two new trenches a month. The danger comes during
flood season when fast-moving water nears the top of a 22-foot
tall levee.
Following Gov. Gavin Newsom’s decision to withdraw permits for
the proposed Twin Tunnels project in favor of a smaller single
tunnel, Rep. John Garamendi, D-Solano, issued a letter to the
governor expressing support for the decision while also
outlining alternative water plans.
Before California’s Central Valley became known as an
agricultural powerhouse, it contained one of the largest
expanses of streamside forest and wetland habitat in North
America. … Much of that landscape has been transformed into
farmland and urban areas, but at the Cosumnes River Preserve, a
unique partnership of nonprofits and state, federal and local
governments has conserved over 50,000 acres that provide
resources for a variety of wildlife.
Paddlers of every skill and age from the U.S. and abroad will
be making their way down the Sacramento River on May 26 in the
California River Quest. … The course flows through riparian
forests and oak woodlands “teaming with wildlife and plants” as
well as a section that runs through a lava canyon, said
Matthews.
DWR has not yet disclosed whether it intends to withdraw the
WaterFix bond resolutions, which are subject to numerous
challenges in litigation DWR filed to validate the bonds. It
remains unclear what will happen with the validation action now
that the project and cost estimates these items are based on no
longer exist.
Gov. Gavin Newsom killed the divisive twin tunnels project
Thursday, calming fears that have roiled the delta communities
and dominated California water politics for more than a decade.
It is a signature decision for the young administration.
The Newsom administration announced it is withdrawing permit
applications that the Brown administration had submitted to the
State Water Resources Control Board, California Department of
Fish and Wildlife, and several federal agencies. Instead, the
administration said it will begin environmental studies on a
one-tunnel project.
Yes, some fish died — including endangered Chinook salmon — but
overall rebuilding the Fremont Weir has done its job and saved
hundred of others. That was the response of Allen Young, public
information officer for the California Department of Water
Resources, after reports surfaced last week that at least 13
Chinook salmon and other fish couldn’t make it through the weir
designed to get them safely into the Sacramento River and died.
Part of sustaining salmon populations is improving the survival
and fitness of young salmon as they grow for weeks to months
before out-migrating to the Ocean. … This year, UC Davis
Center for Watershed Sciences and California Trout have four
different studies over approximately 100 miles using floating
cages with baby salmon inside.
An automated gate was supposed to open once water levels got
high enough to overflow into the bypass, allowing fish to swim
back into the Sacramento River. But in February … too much
water was pouring through the passage, eroding the structure.
Officials had to close the gate almost entirely, meaning fewer
fish could escape. The Department of Water Resources is now
facing an expensive upgrade to an already multimillion
structure to make it ready for the next rainy season.
In Solano County, near Sacramento, [Alex] Johnson is working on
what he says could be a model for parched ag regions around the
state. … Last month, working with IBM and a company
called SweetSense, Johnson’s team began deploying simple,
solar-powered sensors, originally developed to monitor creaky
groundwater pumps in East Africa. The sensors will be used to
detect how much water is flowing in real-time. … Farmers will
use that data to trade their water on (what else?) a blockchain
platform.
Rep. Josh Harder, D-Turlock, thinks there is a better way to
find water solutions for California’s Central Valley and to
stop squandering water in wet years that’s needed in dry years.
His bipartisan water legislation unveiled Wednesday promises
federal support for storage and innovation projects to address
shortages that too often plague Valley agriculture and
communities.
In California, the amount of water exiting aquifers under the
state’s most productive farming region far surpasses the amount
of water trickling back in. That rampant overdraft … has
ignited interest in replenishing aquifers in California’s
Central Valley through managed flooding of the ground above
them. But until now there has been no reliable way to know
where this type of remedy will be most effective.
For centuries, the Delta was a dynamic and rich ecosystem of
tidal wetlands, riparian forests, and vast seasonal
floodplains. But about 98 percent of the native habitat
disappeared after the Gold Rush and a population boom across
the Golden State.
Despite a decades-long rescue effort, the tiny delta smelt
appears closer than ever to vanishing from its only natural
home, the Sacramento-San Joaquin Delta. Now, some worry it
won’t be long before the only place the once-abundant species
exists is within the confines of an artificial tank.
Frustration was evident, whether it was from a flooded
homeowner or a government agency trying to explain its
processes during Wednesday’s “listening session” regarding
flooding in north Chico. … Despite the anger, there seemed to
be some progress, whether it was the cleaning of Rock Creek
west of Highway 99 by the Rock Creek Reclamation District, or
more property owners funding efforts themselves. Lucero
suggested that property owners could pay more into the existing
county service areas set up for drainage maintenance.
A total of 300,000 salmon were released into the Sacramento
River on Saturday. Half were dropped at their usual location at
Coleman Fish Hatchery near Anderson in Shasta County, and the
other half were released 75 miles downstream, at Scottys
Landing on River Road near Chico. Surgeons fit the fish with
tiny radio transmitters so they can more easily study their
survival chances and homing instincts.
Residents in north Chico say they have never seen flooding like
the deluge that came their way this year, and they want to know
how to stop it. Storm water from Rock Creek and Keefer Slough
surged into their backyards, front yards, and in some cases
into their homes. It crept into orchards and overtook Highway
99, north of Chico and continued westward.
Eldorado Irrigation District staff said the proposed
improvements and replacements are needed because the existing
equipment does not allow selective temperature withdrawal at
multiple elevations for the benefit of downstream fisheries. In
addition the existing pumps and boosters have reached the end
of their useful life, having undergone multiple repairs over
the years.
Bruce Babbitt, the former Arizona
governor and secretary of the Interior, has been a thoughtful,
provocative and sometimes forceful voice in some of the most
high-profile water conflicts over the last 40 years, including
groundwater management in Arizona and the reduction of
California’s take of the Colorado River. In 2016, former
California Gov. Jerry Brown named Babbitt as a special adviser to
work on matters relating to the Sacramento-San Joaquin Delta and
the Delta tunnels plan.
Assemblyman Jim Frazier spoke out in frustration Wednesday when
his bill to increase local representation on the Delta
Stewardship Council died Tuesday in a committee hearing. Unable
to get his bill past the Assembly Water, Parks and Wildlife
Committee, Frazier blamed Southern California water special
interests
Will hatchery-raised salmon have a better chance of surviving
their journey to the Pacific Ocean and back if they get a
75-mile head start? That’s the question a three-year study
hopes to answer for the U.S. Fish and Wildlife Service and four
partner organizations. The plan Saturday is to release 180,000
salmon fry into the Sacramento River 75 miles downriver from
the Coleman National Fish Hatchery.
The Anderson Cottonwood Irrigation District, or ACID, Canal was
covered in tree debris after the snow and rain storms. The
workload was enough that Congressman Doug Lamalfa called in the
California Conservation Corps.
People living in flood-prone areas throughout Shasta County
seemed to be breathing easier Friday after a long winter
dealing with high water threats. For months, many have been
watching the rivers and creeks around their homes, in case the
waters started to rise. However, despite wet weather and
increased water releases from Keswick Dam this week, the
residents we spoke with Friday say their waterways are staying
at manageable levels.
Administered by the National Park Service (NPS), NHAs are
defined by NPS as a grassroots, community-driven approach to
heritage conservation and economic development. They differ
from national parks in several significant ways. Primarily, NPS
does not take ownership of the land encompassed within an NHA
and no land-use restrictions are placed upon landowners.
Specifically, the Feather River Recovery Alliance is asking
FERC to not reissue a license to the state Department of Water
Resources to operate the Oroville Dam until terms of the
agreement are renegotiated, including a new recreation plan.
The group says it received 6,469 local signatures on the
petition.
Tehama and Butte counties teamed up Friday to host a Northern
Sacramento Valley forum on sustainable groundwater held at
Rolling Hills Casino. … The forum was a chance to look at
neighboring agencies and see similarities and differences as
well as how they are progressing in the planning, Fulton said.
It was a place to connect with the agency in their area so they
would know where to go if they had questions.
Sacramento County homeowners living in flood-prone areas may be
eligible for a grant to elevate their houses above identified
flood levels. The Federal Emergency Management Agency announced
it will fund a $2.6 million flood mitigation grant, which could
help dozens of homeowners in the county.
Four months after the Camp fire destroyed the northern
California towns of Paradise and Magalia, city council members
in the neighboring town of Chico voted this week to declare a
climate emergency that threatens their lives and well-being.
One video follows Matthew Sligar on a “typical 14-hour workday”
during the planting season. Another offers a step-by-step
explanation of how rice is planted in Butte County. In others,
he takes viewers on virtual tractor rides and demonstrates
important tools, like his autonomous agriculture drone. Sligar
doesn’t shy away from controversial topics, either, such as
weed and pest control management and water usage.
It worked. Oroville Dam’s main flood-control spillway reopened
for business Tuesday morning, releasing a gentle sheet of water
into the Feather River for the first time since the 2017 crisis
that sent 188,000 people fleeing for their lives. … It was a
far cry from the scene two years ago, when the massive sinkhole
in the spillway turned water releases into an angry, boiling
mess…
An oversight at the Coleman National Fish Hatchery
resulted in the death of some 390,000 fall Chinook salmon this
week. Water was shut off to one of the hatchery’s raceways and
wasn’t turned back on during fish-tagging operations Thursday
night..
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.
On our Bay-Delta Tour June 5-7, participants will hear from a
diverse group of experts including water managers,
environmentalists, farmers, engineers and scientists who will
offer various perspectives on a proposed tunnel project that
would carry water beneath the Delta, efforts to revitalize the
Delta and risks that threaten its delicate ecological balance.
