Experts say it’s likely not a matter of if, but when, intense
rainfall triggers mudslides that threaten the properties and
lives of thousands of people in the Santa Cruz Mountains. The
area has seen these disasters before: In January 1982, the Love
Creek mudslide killed 10 people near Ben Lomond. But the CZU
Lightning Complex, larger than any fire in the region’s
recorded history, created an unprecedented hazard.
As the Colorado River Basin’s managers wrestle with thorny
questions around the proposed Lake Powell Pipeline, a colleague
who works for a Lower Colorado River Basin water agency
recently asked a question that goes to the heart of the future
of river management: With land in the Lower Colorado River
Basin, why doesn’t Utah have a Lower Basin allocation?
In 2011, heavy snows in the Rocky Mountains filled the Colorado
River, lifting reservoirs—and spirits—in the drought-stricken
U.S. Southwest. The following year, however, water levels
dropped to nearly their lowest in a century… Now, scientists
say they may have come up with a potential early warning system
for the Colorado’s water levels—by watching temperature
patterns in the Atlantic and Pacific oceans, thousands of
It all started with a 2002 state law demanding quake-resilient
water delivery. Nearly $5 billion later, San Francisco has
retrofit the system from Hetch Hetchy to the city, just now
crossing the finish line on the shore of Lake Merced.
Congressman John Garamendi, who represents the northern half of
Lake County, on Friday submitted a formal comment to the
Federal Energy Regulatory Commission opposing removal of Scott
Dam on the Eel River at Lake Pillsbury and demanding that Lake
County have an equal seat at the table for determining the
future of Potter Valley Project and the lake.
ACWA on Oct. 15 submitted “A Roadmap To Achieving the Voluntary

Aquatic ecologist Steve Lee is concerned that abundant water
may not always be part of the Sonoma Valley story. … So Lee’s
rebuilt home was designed to capture the runoff, and store it
in a series of 5,000-gallon gravity-fed tanks. He’s got 11 of
them scattered across his property, harvesting water from the

A critical piece of the Clean Water Act, known as Section 401,
allows states and tribes to work with the federal government to
ensure that rivers are protected and that projects meet the
needs of local communities. Unfortunately, the Environmental
Protection Agency recently created new rules for how states and
tribes can use their authority under Section 401.
President Donald Trump on Tuesday created what he called a
“subcabinet” for federal water issues, with a mandate that
includes water-use changes sought by corporate farm interests
and oil and gas. … The first priority set out by the
executive order is increasing dam storage and other water
storage, long a demand of farmers and farm interests in the
West in particular. That includes California’s Westlands Water
District, the nation’s largest agricultural water district.
A new California Biodiversity Collaborative will help determine
how to carry out an executive order from Gov. Gavin Newsom
aimed at conserving 30% of California’s land and marine areas
by 2030—and agricultural organizations said they would
participate to assure the collaborative recognizes stewardship
efforts carried out on the state’s farms and ranches.
The South Fork Eel River is considered one of the highest
priority watersheds in the state for flow enhancement projects.
Forested tributaries like Redwood Creek provide refugia habitat

cumulative impacts of legacy logging and unregulated water
The industry that operates America’s hydroelectric dams and
several environmental groups announced an unusual agreement
Tuesday to work together to get more clean energy from
hydropower while reducing the environmental harm from dams, in
a sign that the threat of climate change is spurring both sides
to rethink their decades-long battle over a large but
contentious source of renewable power. The United States
generated about 7 percent of its electricity last year from
hydropower, mainly from large dams built decades ago, such as
the Hoover Dam, which uses flowing water from the Colorado
River to power turbines.
The U.S. Environmental Protection Agency (EPA) has announced a
$108 million Water Infrastructure Finance and Innovation Act
(WIFIA) loan to the Stockton Public Financing Authority to help
modernize the city’s wastewater treatment facility and reduce
nitrogen discharges to the San Joaquin River.
The North Complex Fire has burned a large portion of Lake
Oroville’s watershed. This could lead to hazardous water
quality after winter rains run all of that sediment into the
lake and the effects could last decades. However, how water
quality could be affected by the fire is still largely unknown.
Prescribed burning … targets brush, grasses, and other
accumulated vegetation, along with dead and downed trees, to
improve ecosystem health and reduce the fuels that power
wildfires. … “We’re trying to encourage a cultural shift in
our relationship with wildfire,” says Sasha Berleman, a fire
ecologist who runs a prescribed burn training program based in
the San Francisco Bay Area. “Fire isn’t going away, so let’s
change how we’re living with it.”
Unbeknownst to many, some voters will pick five new members of
the Board of Directors of the Westlands Water District. GV Wire
had a chance to speak with two of those… Both offered
insights into how Westlands can change its reputation, how
farmers can change their approach, and what their biggest
adversaries are in the fight for water.
A new experiment is looking into how drought conditions, like
we’re currently in, can affect water traveling downstream in
the Colorado River. The pilot project involved shepherding
water from a high mountain reservoir to the Colorado-Utah state
The California Department of Water Resources (DWR) recently
launched an environmental justice community survey to gather
input to inform Delta Conveyance Project planning. The survey,
entitled, “Your Delta, Your Voice,” seeks direct input from
communities that may be disproportionately affected by the
Protecting intact peatlands [such as those in California] and
restoring degraded ones are crucial steps if the world is to
counter climate change, European researchers said Friday. In a
study, they said peat bogs, wetlands that contain large amounts
of carbon in the form of decaying vegetation that has built up
over centuries, could help the world achieve climate goals like
the limit of 2 degrees Celsius of postindustrial warming that
is part of the 2015 Paris agreement.
If certain hay species retain more nutrients than others when
on low-water diets, then ranchers know their cattle will
continue to eat well as they evaluate whether they can operate
their ranches on less H20…. Any water saved could be left in
the Colorado River, allowing it to become more sustainable,
even as the West’s population grows and drought becomes more
The Forest Service’s use of herbicides and pesticides has
raised occasional alarm from environmental groups, which point
to the chemical’s potential to harm wildlife or water supplies,
or to have long-term effects on people who apply them. In some
regions, they say, scarcely a tree-planting project occurs
without the use of chemical herbicides.
A team of scientists at Utah State University has developed a
new tool to forecast drought and water flow in the Colorado
River several years in advance. Although the river’s headwaters
are in landlocked Wyoming and Colorado, water levels are linked
to sea surface temperatures in parts of the Pacific and
Atlantic oceans and the water’s long-term ocean memory.
In the new study, scientists at The University of Texas at
Austin in collaboration with the Union of Concerned Scientists
found that leading climate projections used by the state
strongly agree that climate change will shift the timing and
intensity of rainfall and the health of the state’s snowpack in
ways that will make water management more difficult during the
Newsom, who made the announcement in a walnut orchard 25 miles
outside of Sacramento, said innovative farming practices,
restoring wetlands, better managing forests, planting more
trees and increasing the number of parks are all potential
tools. The goal is to conserve 30% of the state’s lands and
coastal waters in the next decade as part of a larger global
Despite that reduction in flow, total storage behind Glen
Canyon and Hoover dams has dropped only 2.6 million acre feet.
That is far less than you’d expect from 12 years of 1.2 maf per
year flow reductions alone. That kind of a flow reduction
should have been enough to nearly empty the reservoirs. Why
hasn’t that happened? Because we also have been using less
Water providers in California face myriad challenges in
sustainably providing high quality drinking water to their
customers while protecting the natural environment. In this
blog post, I explore the stresses
that surface and
groundwater quality challenges pose for California’s
retail water agencies.
On the heels of a historic drought, at the beginning of the
implementation of historic groundwater legislation, and in
light of potential flooding, Porterville will have more water
in the future and a larger dam to prevent it from damaging the
A relatively new water budgeting platform appears to be working
well for producers in Kern County. The Rosedale-Rio Bravo Water
Storage District has worked with multiple stakeholder partners
to develop the Water Accounting Platform to help growers more
accurately track water use.
The bill, which was written by state Sen. Ben Hueso, also aims
to address some of the binational challenges in managing the
watershed. The plan that the California EPA is putting together
will create a framework for how California can work with the

In California’s Placer County, an unusual partnership between a
county water utility, the U.S. Forest Service and
environmentalists is taking on the work to prevent catastrophic
fires on more than 11,000 hectares in the northern Sierra
Nevada Mountains. The partnership arose from the ashes of
2014’s King fire.
San Diego County Water Authority is looking into the
possibility of building a pipeline (aqueduct, more accurately)
to get its water directly from the Imperial Valley instead of
indirectly through the Metropolitan Water District (MWD) in Los
Angeles. SDCWA and MWD have a history of litigation about how
much MWD can charge for transporting water from Lake Havasu
through MWD’s Colorado River Aqueduct to reservoirs in northern
San Diego County.
Californians are understandably focused on the wildfires that
have charred more than 3 million acres and darkened our skies –
forcing us to find masks that protect us from both COVID-19 and
smoke. But Californians should also pay attention to the
multiple hurricanes that have devastated the Gulf Coast this
season. These disasters have much in common.
U.S. and tribal officials are celebrating completion of a $34
million fish bypass system at a Nevada dam that will allow a
threatened trout species to return to some of its native
spawning grounds for the first time in more than a century.
Construction of the side channel with fish-friendly screens is
a major step toward someday enabling Lahontan cutthroat trout
to make the same 100-mile journey — from a desert lake
northeast of Reno to Lake Tahoe atop the Sierra — that they did
before the dam was built in 1905.
The Georgetown Divide Public Utility District reported Sept. 23
that its release of 2,000 acre-feet of water from Stumpy

If you look closely in the waters of Deer Creek, near Nevada
City, Calif., something strange may catch your eye; lying in
globules amongst the gravel is quicksilver, or liquid elemental
mercury. Carrie Monohan, head scientist for the Sierra Fund,
lives next to Deer Creek, and became concerned about mercury
contamination in the waterways when she pulled liquid mercury
from the water in a turkey baster.
Linking floating solar panels with hydropower could produce the
equivalent of 40% of the world’s electricity, according to a
new study by researchers at the Department of Energy. … The

the technical potential of the hybrid concept.
The recent downgrade in the forecast for the flow of water in
the Colorado River should be a death punch to the proposal to
build a new pipeline out of Lake Powell. The pipeline was
already a major threat to Las Vegas and much of the rest of the
Southwest; now the threat risk is heading off the charts.
According to river flow data, there is currently almost no
water flowing into Walker Lake, a common condition. Today,
where the riverbed meets the lake is an ooze of mud. The lake
is all but biologically dead. But a decades-old public trust
lawsuit made a move forward in its glacial process through
federal courts last week, and advocates are hopeful Walker
Lake, a cornerstone of the regional economy and ecology, can
one day be revived.
On Wednesday, the Bureau of Reclamation joined its partners,
U.S. Fish and Wildlife Service and Farmers Conservation
Alliance, to celebrate the completion of the Derby Dam Fish

natural spawning grounds for the first time since 1905.
California Gov. Gavin Newsom vetoed a bill that would have
provided funding to fix the ever-sinking Friant-Kern
Canal. SB 559 would have required the Department of Water
Resources to report to the legislature by March 31, 2021, on
federal funding for the Friant Water Authority or any other
government agency to restore the capacity of the Friant-Kern
Canal. The bill would also have required DWR to include a
proposal for the state to pay up to 35 percent of the cost of
In December, the Metropolitan Water District Board of Directors
will be asked to support a motion to fund a portion of the
planning costs for the Delta Conveyance Project. In preparation
for the upcoming vote, staff began a series of presentations
for the special committee on the Bay-Delta to prepare the
directors for the vote.
Assessments of the worst-case scenario predict the Bay may rise
a damaging 1.9 feet by 2050 and as much as nearly 7 feet by
2100. Restoring even a fraction of the Bay’s lost wetlands
would provide long-lasting benefits.
Tensions between Mexico and the United States over water
intensified this month as hundreds of Mexican farmers seized
control of La Boquilla dam in protest over mandatory water
releases. The protesters came from parched Chihuahua state,
nearly 100 square miles of land pressed against the U.S.
border, where farmers are opposing the delivery of over 100
billion gallons of water to the United States by October 24.
Called the Three Creeks Parkway Restoration, the $9 million

In June, the Trump administration’s new version of which waters
are protected under the Clean Water Act took effect. The new
rule is an about-face from the Obama-era regulations, and
Arizona state regulators are trying to make sense of it.
Gov. Gavin Newsom on Tuesday added his signature to a new law
that orders the formation of a commission to study the
feasibility of lithium extraction around the Salton Sea. Local
politicians hope the commission will lead to the creation of a
green economy around the state’s largest lake, which is a
geothermal hotspot. It was one of several bills focused on
California’s environment that Newsom dealt with this week.
Santa Clara County’s largest reservoir will soon be nearly

Some of the largest users of the Ventura River recently
released their proposal to settle litigation and potentially
stave off a water-rights adjudication. The plan includes
multiple habitat restoration projects intended to help
endangered steelhead trout, but largely avoids any changes to
water use. Before it goes to a judge, however, other parties
likely will weigh in, including the state.
Regional water conservation groups and a Clark County
commissioner welcomed a request by Utah officials Thursday to

The Klamath Basin used to be the third most important
salmon-bearing watershed in the Pacific Northwest. Now, only a
fraction of those runs remain. The multiple reasons for their
decline are complex and interconnected, but they all have to do
with how water moves through the system.
Although droughts may not garner as much attention as acute
extreme events like hurricanes, floods or fires, their
multidimensional effects are vast. … A multi-year drought in
California has seen the number of breeding waterfowl dip 46%
below average as wetlands shrink and dry up.
The monsoon season — that period from mid-June through
September that each year brings rains to the Mojave Desert and
other areas of the Southwest from the tropical coast of Mexico
— has been a dud this year. Las Vegas is in the middle of a
record-breaking stretch without rain, and residents should be
prepared for it to stay that way, scientists say.
Three Coachella Valley high schoolers kayaked across the Salton
Sea Saturday to raise awareness about the social and ecological
crisis unfolding as California’s largest lake continues to

When the Creek Fire erupted on Sept. 5 and chewed through the
forest toward Southern California Edison’s Big Creek power
system, little did anyone know how that might affect grape
growers in Delano nearly a month later.
Stanford scientists have identified a new kind of “landfalling
drought” … that can potentially be predicted before it
impacts people and ecosystems on land. … They
found that droughts that make landfall in the region have been
associated with certain atmospheric pressure patterns that

Behind the apocalyptic wildfires in California and Oregon,
another ominous trend is creeping across the globe: Everywhere
in the world, trees are dying, with the biggest trees going
first. Entire forests are threatened worldwide.
Climate change is driving the scale and impact of recent
wildfires that have raged in California, say scientists. Their
analysis finds an “unequivocal and pervasive” role for global
heating in boosting the conditions for fire. California now has
greater exposure to fire risks than before humans started
altering the climate, the authors say.
In Utah, there is a significant effort underway to build a
water delivery pipeline from Lake Powell to transport part of

At the September meeting of Metropolitan’s Water Planning and
Stewardship Committee, Laura Lamdin, an associate engineer in
water resource management, gave a presentation on how the
United States and Mexico built a collaborative relationship,
the many accomplishments that have come as a result, and a look
at the work currently in progress.
Last week, the Nevada Supreme Court ruled that the state’s
fundamental obligation to protect natural resources for future
generations did not allow it to reallocate water rights issued
under state law. The decision appeared to rule against
litigants pushing to restore Walker Lake, where the use of
upstream water rights has decreased the amount of water that
reaches the lake.
A new study concludes that, by building dams, forming ponds,
and digging canals, beavers irrigate vast stream corridors and
create fireproof refuges in which plants and animals can
shelter. In some cases, the rodents’ engineering can even stop
fire in its tracks.
In 2012 a team of salmon researchers tried a wild idea: putting
pinky-sized Chinook on a rice field in the Yolo Bypass, a vast
engineered floodplain designed to protect the city of
Sacramento from inundation. … Now, after nearly a decade of
testing fish in fields, a new paper in San Francisco Estuary
and Watershed Science outlines lessons learned as well as next
steps in managing floodplains for salmon.
The Park and Natural Resource Manager for Chico and Butte
County Linda Herman confirmed the dead fish being reported are
on the back side of the pond near the fresh water area, saying
the fish have succumbed to lack of oxygen in the water due to a
thick layer of ash that has formed atop many parts of the pond.
The project would restore capacity from 1,600 cubic-feet-per
second to the original 4,000 cubic-feet-per second at what the

under the first plan of its kind in the Central Valley of
A crisis could be approaching. The two giant reservoirs on the
Colorado River are both below 50 percent of capacity. If
drought causes even more drastic drops, the Bureau of
Reclamation could step in to prioritize the making of
electricity by the hydro plants at lakes Mead and Powell. No
one knows what BuRec would do, but it would call the shots and
end current arrangements.
A House Agriculture subcommittee this week will examine the
response to Western wildfires, less than three months after its
chairwoman predicted the COVID-19 pandemic would make this fire
season like no other.
For this reason, public water agencies and DWR have publicly
negotiated amendments to their long-term water supply contracts
in order to better plan the future of their local water supply
portfolios. … The State Water Contractors applaud this
coordinated and collaborative effort, which provides
flexibility for single and multi-year non-permanent water
transfers and exchanges.
After years spent developing this project and making
adjustments to respond to stakeholder concerns, it became
obvious that we needed to take more time to address objections
raised by the community of Marina — namely that our project
would be built in their backyard without them receiving any
benefit from it.
Floodplains were the historic rearing areas for juvenile
salmon, and the remaining floodplains in California are an
important food-rich habitat as present-day salmon grow and
attempt to survive their trip out to the ocean. We sat down
with Hailey Wright, a Department of Water Resources
environmental scientist, to discuss the salmon lifecycle and
her work designing and implementing projects in the Yolo
Anderson Reservoir will be closed to boating, fishing and all
recreational activities for the next several years starting
Oct. 1. That’s when the local water district will begin
draining the lake in order to begin construction on a new
discharge tunnel and seismically retrofitted dam.
Along with being a global leader on addressing climate change,
California is the seventh-largest producer of oil in the
nation. And across some of its largest oil fields, companies
have for decades turned spills into profits, garnering millions
of dollars from surface expressions that can foul sensitive
habitats and endanger workers, an investigation by The Desert
Sun and ProPublica has found….Under state laws, it’s illegal
to discharge any hazardous substance into a creek or streambed,
dry or not.
The Embarcadero faces severe threats, with regionwide
repercussions from both earthquakes that could undermine the

A rapid-fire review of potential fixes to the Friant-Kern Canal
favors building a replacement canal for 20 miles alongside the
existing canal where land subsidence has caused it to sag,
severely restricting water flow, according to final
environmental documents released Friday.
Over the years, these groups united against a single cause: the
Southern Nevada Water Authority’s “Groundwater Development
Project,” a proposal to pump 58 billion gallons of water a year
300 miles to Las Vegas from the remote rural valleys of Nevada
and Utah. … In May, their three decades of resistance to the
pipeline ended in victory: The project was terminated.
For years, a stretch of Chorro Creek near Hollister Peak ran
through active farmland, where its flow was diverted for
irrigation and its banks were shored up by levees, blocking the
water’s natural access to its floodplain. … After nearly two
decades of planning and fundraising, the Estuary Program and
its partners recently completed a major restoration of the
When fires burn up vegetation, the charred remains become
hydrophobic—meaning they repel away any water. The soil is also
very dry, which counterintuitively makes it harder for water to
infiltrate. … Fires can also destroy the natural clumps in
soil, increasing their erodibility. Altogether, this means that
water is hitting the ground with more force and the soil is
unable to suck it up.
The main stormwater issue associated with solar arrays is the
concentrated discharge of stormwater runoff at the solar panel
drip line, which can act like un-guttered roofs that channelize
and accelerate stormwater flow. Instead of traveling as sheet
flow across a fallow field, capped landfill, or macadamized
parking area, stormwater now lands on the surface in
channelized sheets that must be carefully managed to prevent
soil scouring, erosion, and contamination…
A team of scientists, led by the University of Arizona, has
developed a new blueprint for arid-land agriculture using wild,
native crops and modern growing techniques. The 14 researchers

When the Creek Fire exploded to 160,000 acres in just 72 hours,
ripping through a jewel of the Sierra Nevada just south of
Yosemite National Park, California and the world looked on in
horror and surprise. But the stage had long been set for the
megablaze, one of a half-dozen transforming millions of acres
of Golden State landscapes to ash. Droughts supercharged
by climate change dried out vegetation, aiding its transition
Former U.S. Secretary of the Interior Bruce Babbitt writes that
a “Grand Bargain” in California water is needed to end the
“political culture of deferral” and allow major water projects
to advance. On the contrary, what’s needed is an adult
regulator that will make hard choices that water users refuse
The years-long fight between the Imperial Irrigation District
and farmer Michael Abatti over control of Colorado River water
could be nearing its grand finale in the California Supreme
Court. After Abatti requested last month that the state’s
highest judicial body take up his case, the water district
filed its opposition on Monday.
A top water regulator from New Mexico yesterday warned senators
that hardrock mines, wastewater facilities and other industrial

Poor erosion control on the 258-acre site unleashed soils into
streams of the Russian River watershed and put fish and other
other aquatic wildlife at risk, regulators found, counteracting
millions of dollars spent to improve habitat and restore
imperiled, protected runs of salmon and steelhead…
The right balance of nutrients is crucial for a healthy coastal
ecosystem. If rivers deposit too much nitrogen and phosphorus
in coastal areas, algae that flourish on those nutrients can
cause dead zones; if too little silicon flows downstream,
organisms that depend on it will die off.
For 75 years, through tensions and disputes over immigration,
narcotrafficking and trade, Mexico and the United States have
sent each other billions of gallons of water annually to
irrigate farms along the border under a treaty signed during
World War II. But today, the 1944 agreement is facing
increasingly violent opposition in drought-parched Chihuahua
state, where protesters have seized control of a major dam to
dramatize the plight of farmers…
Jacob Pounds, environmental program coordinator with the Blue
Lake Rancheria, told the Outpost this afternoon that the
bacteria — well established in other local waterways, such as
the Eel and the Klamath — has never been confirmed in the Mad
Wildfires started burning in California early again this dry
season—more than two million acres have burned so far. Larger
and larger wildfires are occurring as new heat records are
being broken each year. Firefighting efforts have leaned
heavily on aerial spraying of fire retardants, but their
environmental and health effects [including on fish and
waterways] are little studied …
Scientists at Salo Sciences, a startup that works on technology
for natural climate solutions, began creating the tool after
interviewing dozens of experts in California about the state’s
challenges with wildfires: They need more detailed, up-to-date
information about the forests so they can better predict how
fast and in what direction fires will spread…
Following a hot and extremely dry spring and summer, the Bureau
of Reclamation’s latest projections show that in a scenario of
continuing drought between now and 2025, the chances of Lake
Mead falling into a shortage has increased to nearly 80%. The
odds of the reservoir dropping to critically low levels by 2025
under this scenario was estimated at nearly 20%.
The Sierra Nevada provides more than 60 percent of California’s
water supply and sustains a globally important agricultural
region. Quantifying the water-related benefits can be critical
in showing the true value and cost-benefit of forest
management. But until now, there hasn’t been enough locally
relevant data to incentivize restoration projects.
Responding to the lack of progress in 2017, the State Water
Resources Control Board ordered the California Natural
Resources Agency to adopt a 10-year plan to implement projects
to suppress the harmful dust and restore habitat. … But in
the three years since the water board’s order, progress has
been dismal, even though there is more than $350 million
available to implement the plan.
Every September for the last 22 years, the South Yuba River
Citizens League has hosted a Yuba River Cleanup with the help
of the California Coastal Commission. This year, the river’s
need for some tender, loving care has only grown as the region
reckons with more visitors, more single-use plastics and less
accountability amidst the pandemic.
Mexico’s water wars have turned deadly. A long-simmering
dispute about shared water rights between Mexico and the United
States has erupted into open clashes pitting Mexican National
Guard troops against farmers, ranchers and others who seized a
dam in northern Chihuahua state.
Lake Powell isn’t in Southern Nevada. Rather, it’s about four
hours away by car in southern Utah. But some environmentalists
say the water consumption of St. George, Utah, and neighboring
communities could have a direct and deleterious impact on the
Las Vegas water supply.
One of the most severe examples is the San Lorenzo Valley Water
District, which serves parts of inland Santa Cruz County, in
central California. More than 7 miles of an HDPE plastic water
supply pipeline were destroyed in the CZU Lightning Complex
Fire, according to Rick Rogers, the district manager.
The cuts are a plan to keep Lake Mead, a reservoir at the
Arizona-Nevada boundary, functional. Water levels have
precipitously dropped as a result of historic overallocation
and a drought that started in 2000. … ASU Now checked in with
Sarah Porter of the Kyl Center for Water Policy at the Morrison
Institute on how these new developments will impact the Copper
State and its residents.
As wildfires burn across California, temperatures hit record
highs, and communities cope with the COVID-19 crisis,
biologist Caroline Brady is helping respond to a different
disaster: the worst avian botulism outbreak that anyone can
remember at the Klamath Basin National Wildlife Refuge Complex.
Roughly a thousand acre-feet of water won’t make or break the
Colorado River. But for many who live in counties that border
the river, even losing a few drops of water to central Arizona
poses a major threat to their way of life.
A major expansion of Los Vaqueros Reservoir took a step forward
with release of the final feasibility report by the U.S. Bureau
of Reclamation that concluded the initiative is economically
viable. The reservoir is owned and operated by the Contra Costa
Water District, and the project will increase its capacity by
more than 70% when complete.
California is on track to get drier over the coming decades.
But that doesn’t mean the golden state’s water woes come only
from too little rain. In a new study, researchers at UC Santa
Barbara and UCLA warn that flooding potential associated with
extreme precipitation events is set to sharply increase.
“When a forest burns in a wildfire, should we expect it to
return as it was before?” Research scientist Jonathan Coop and
his team pose this question. It addresses a critical conundrum
in ecology: How do ecosystems recover from disturbance and why?
The San Francisco Bay-Delta is literally threatened from all
sides: rising sea levels from the ocean, disruptions to
sediment supply from upstream, and within the Bay-Delta itself,
development and other land use changes have left only a tiny
fraction (5%) of marshland untouched. … A recent study by
scientists at the U.S. Geological Survey used historical
streamflow and sediment data to predict what will happen to the
Bay-Delta under varying levels of climate change.
Coal miners, stone quarrying companies, and other businesses
are rushing to lock down any exemptions to federal water
jurisdiction for at least five years, under changes the Trump
administration recently made to the nation’s water rule. … A
decision that might in some instances have taken multiple site
visits and nearly three years now can come as quickly as a day,
the data show.
Reclamation announces a virtual open house website for the
Shasta Lake Water Resources Investigation Draft Supplemental
Environmental Impact Statement. Website visitors will be able
to learn more about the project, review summaries of Draft
Supplemental EIS chapters, and submit comments.
The idea was to lower the flows while temperatures were still
warm enough to dry out the caddis larvae. That required buy-in
from local merchants and the Bureau of Reclamation, local
tribes and others. They were able to do it, and on Aug. 27, the
first of two flow reductions took place. When the river
dropped, people pitched in for a day of river cleanup.
Mike Halpert, deputy director of the Climate Prediction Center,
said that as a result of La Niña, Southern California, as well
as most of Arizona and New Mexico, could “tilt toward dry” this

The pending removal of the Upper York Creek Dam has put a stop
to a daily $70 fine that’s been levied against the City of St.
Helena for almost eight years. Thanks to rapid progress on the
long-awaited project, which will improve fish passage and
restore habitat along York Creek, the National Oceanic and
Atmospheric Administration has suspended the $70 per day
penalty the city has incurred since November 2012…
While California’s climate has always made the state prone to
fires, the link between human-caused climate change and bigger
fires is inextricable, said Park Williams, a bioclimatologist
at Columbia University’s Lamont-Doherty Earth Observatory.
The Mexican National Guard said Wednesday that two people had
died in a gunfight with military police near a protest at a dam
that diverts water away from an area hit by drought to the
United States. … The protest comes amid plans to divert more
to the United States due to a “water debt” Mexico has accrued
under a 1944 water-sharing treaty between the countries.
The most pressing risk is debris that could clog the San
Lorenzo River near River Street and Highway 1 where water
enters the city’s system, said Santa Cruz Water Director
Rosemary Menard. The San Lorenzo River is the city’s largest
water source. It represents about 45% of the water supply.
Less than two years after the most destructive fire in
California history tore through Paradise, the same region was
under siege from a second monster firestorm that quickly grew
to more than 250,000 acres, sweeping through mountain hamlets
and killing at least three people. … Across the state, 28
major wildfires have prompted more than 64,000 people to
Restoring specific “functional flows” would better support fish
migration and spawning, water quality, dry-season base flows,
and physical conditions that support aquatic species. A panel
of experts, moderated by PPIC senior fellow and study coauthor

Nevada officials raised numerous concerns Tuesday about a
proposed project to pipe large quantities of Colorado River
water roughly 140 miles from Lake Powell to southern Utah…
Six of the seven states that use the Colorado River also sent a
letter to federal water managers Tuesday asking them to refrain
from completing project permitting…
By killing millions of trees in the Sierra National Forest, the
historic drought that ended in 2017 left an incendiary supply
of dry fuel that appears to have intensified the fire that’s
ravaged more than 140,000 acres in the southern Sierra Nevada,
wildfire scientists and forestry experts said.
In 2010, tribes joined the company that owns the dams and other
stakeholders in an agreement to remove the dams in 2020. The
plan was later delayed to 2022, and now it may stall again
because of a recent decision by federal regulators.
The water wars are far from over, a point made clear in a
just-released feature-length documentary, “Until the Last
Drop.” If you can block from your mind the old Folgers “good to

combination of dripping water with a fight to the last drop of
Arizona’s top water regulator has endorsed a company’s proposal
to take water from farmland near the Colorado River and sell it
to the fast-growing Phoenix suburb of Queen Creek. The plan,
which still would require federal approval, has generated a
heated debate about whether transferring water away from the
farming community of Cibola could harm the local economy, and
whether the deal would open the gates for more companies to buy
land near the river with the sole aim of selling off the water
Creek Week (starting the fourth week of September), and
California’s Coastal Cleanup Day all coincide in September to

Groups in the Tahoe Basin are using new technology to fight
invasive species and decreasing lake clarity. Researchers at
University of Nevada, Reno and Tahoe Regional Planning Agency
have been testing a UV light equipped vessel to control aquatic
invasive plants in the Tahoe Keys.
Starting in mid-July, the flows in the Noyo River began
dropping faster than in any other summer on record. The river
flow is below 2015 low flows, when the entire state was in a
drought emergency. John Smith, director of Fort Bragg Public
Works, said staff had never before seen water levels in the
Noyo drop so precipitously.
Four aging dams on the Klamath River are coming down. Their
completion between 1921 and 1964 brought hydroelectric power to
Northern California. It also blocked hundreds of kilometers of
fish habitat, causing Chinook salmon to effectively disappear
from the upper river basin. But the removal of dams is no
guarantee the fish will return, so a team of wildlife
researchers hopes it can coax the fish to repopulate the river
by exploiting a new discovery about salmon genetics.
For the first time in years, boats will soon be able to travel
freely again down the Petaluma River. … Once a vibrant
waterway, Petaluma River is now silted in, full of mud. Lt.
Colonel John Cunningham says the river hasn’t had a full
cleaning by the Army Corps of Engineers for nearly 20 years.

EPA Administrator Andrew Wheeler said Wednesday the agency
would pay for more water treatment south of the border, and
work with San Diego to control trash coming into the United
States from Mexico by way of the Tijuana River. Wheeler made
the announcement during a visit to Southern California, a
region long plagued by sewage, water, trash, and other
contaminants flowing from Mexico.
Dams, diversions, and land conversion have substantially
altered California’s rivers and disrupted the processes that
