The gravity-fed Friant-Kern Canal that is key to survival for
15,000 east side San Joaquin Valley farms continues to be
impacted by subsidence. Land near Porterville appears to be
most worrisome where the land has sunk so much due to adjacent
water pumping that the canal has lost 60% of its capacity. As
of July 2018, it was estimated the canal is approximately 12
feet below the original constructed elevation.
The metric identifies the amount of carbon dioxide per
acre-foot of water transported by the State Water Project.
Water districts receiving water from the SWP can use this
metric to understand the emissions of their water supply
chains, and customers can better understand the ‘carbon
intensity’ of the water they purchase.
The latest dustup In California’s water wars, as noted in Dan
Walters’ commentary, revolves principally around the federal
government’s efforts to increase the amount of water supplied
to farms and cities by the Central Valley Project, and a
breakdown in cooperation between the state and federal
government. It seems like everyone is suing each other. But
what are they really fighting over?
Two factors are believed to weigh heavily on the Delta smelt’s
fate. The biggest is the reduction in fresh water in the Delta
since water started flowing southward via the California
Aqueduct in the 1960s. … The other threat to Delta smelt are
larger fish particularly non-native striped bass and largemouth
bass that were introduced to the Delta by man.
It was during the drought in the late-1980s that Robin Kulakow
and her fellow birdwatchers began noticing that Putah Creek was
running dry. The same observation was being made at places such
as Camp Davis, a popular site near the university where youth
paddled their canoes and participated in other activities.
This winter’s decent snowfall has turned into an abysmal runoff
on the Colorado River, thanks to the dry soils heading into the
winter, along with a warm spring. … Our bigger concern is
what happens next year. Are we headed for a multi-year drought?
In 2014, the Cleveland National Forest (CNF) initiated an
effort to restore the migratory corridors for fish and other
aquatic species in the San Juan and Santiago Watersheds by
removing the remnants of small (approximately 2 – 15 ft) dams
constructed by Orange County (California) between 1940-70s.
The gene-editing technology CRISPR has been used for a variety
of agricultural and public health purposes — from growing
disease-resistant crops to, more recently, a diagnostic test
for the virus that causes COVID-19. Now a study involving fish
that look nearly identical to the endangered Delta smelt finds
that CRISPR can be a conservation and resource management tool,
Agricultural runoff is one of the largest sources of pollution
in the nation’s waterways. In recent years, scientific journals
and the media have been filled with reports of toxic algae
blooms and dead zones near and far… Unfortunately, in today’s
highly politicized federal climate, it is unlikely that an
effective solution to this problem will emerge from the U.S.
EPA – at least not at the moment. So efforts by state
regulators are particularly important.
Clear Lake is one of the richest lakes in the state when it
comes to nutrients. That is one reason we have algae blooms as
well as a massive amount of aquatic weeds. Some of the species
of aquatic weeds have been in the lake for more than a million
years and others only a few years. These new arrivals are
classed as foreign invasive weeds.
The Klamath Project, a U.S. government-operated waterworks that
steers runoff from the towering Cascades to more than 200,000
acres of potatoes, alfalfa, wheat, onions and other produce on
both sides of the state line, is running low on supplies. The
local water agencies served by the project say they may not
have water to send to farms beyond next month.
The researchers discovered that salmon survival depends in part
on how long isolated pools spend disconnected from flowing
water: the longer the dry period, the fewer salmon were able to
hang on until the wetter months of fall and winter. And though
fewer salmon overall survived the drought years, the
researchers did find reason for hope. In certain streams and
pools, which the researchers call drought “refuges,” salmon
survival was similar in both drought and non-drought years.
Construction crews will soon begin work to restore Marsh Creek
along a nearly one-mile, treeless stretch near downtown
Brentwood. Crews are expected to close off the trail in the
area from Sungold Park to Dainty Avenue on Tuesday in the first
phase of a project to improve habitat and water quality for
fish and birds and to create a shady, natural creek corridor
for residents while keeping the community protected from floods
Thursday, the Redwood Coast Land Conservancy announced that it
has received three grants totaling over $2.1 million for the
Gualala River Mill Bend Conservation Project that they are
stewarding for the community.
A local non-profit is suing the U.S. Bureau of Reclamation and
a Southern California water district, over a long term water
transfer program. AquAlliance works to protect the Sacramento
River watershed. It is the main plaintiff in a lawsuit that
charges the proposed transfer would send too much water out of
Northern California and would cause severe impacts on area
communities, farms, and the environment.
The State Water Project now expects to deliver 20 percent of
requested supplies in 2020 thanks to above-average
precipitation in May, the California Department of Water
Resources announced. An initial allocation of 10 percent was
announced in December and increased to 15 percent in January.
Today’s announcement will likely be the final allocation update
Outbreaks of E. coli illness that sickened 188 people who ate
romaine lettuce grown in California probably came from cattle
grazing near the farms, the U.S. Food and Drug Administration
said in a report released Thursday. … Investigators concluded
that the illness was centered on ranches and fields owned by
the same grower and that were located downslope from public
land where cattle grazed.
Danika Tsao and a team of surveyors have been working to
complete pre-construction monitoring for the Grant Line Canal
Barrier Project in San Joaquin County. The project is
considered essential for agricultural water use along the
Sacramento-San Joaquin Delta … The area of the Grant Line
Canal is known for being a natural habitat for the Swainson’s
Hawk, which is on the state’s threatened species list.
To address the challenges atmospheric rivers present, the
Center for Western Weather and Water Extremes (CW3E) was
established at the Scripps Institute of Oceanography to advance
scientific understanding of atmospheric rivers and their role
in extreme events and to improve forecasting capabilities.
Earlier this year, a webinar hosted by the Scripps Corporate
Alliance highlighted the Center’s accomplishments.
No one can say yet whether the intense rainfall that preceded
this disaster [in central Michigan] was made worse by climate
change. But global warming is already causing some regions to
become wetter, and increasing the frequency of extreme storms,
according to the latest National Climate Assessment. … That
puts more of the nation’s 91,500 dams at risk of failing,
engineers and dam safety experts said.
The interest is based on the versatility of hemp, which can be
made into different products — biodiesel, fiber, textiles,
clothing, food and nutritional supplements. It’s also because
cotton is no longer grown in the Imperial Valley, and hemp
could be a potential replacement crop that consumes a lot less
water than cotton.
Though the last couple of weekends have seen wet weather, it
hasn’t been enough to keep up with the yearly average in time
for summer in California. The Sierra Nevada snowpack, which is
tested regularly by employees of the California Department of
Water Resources, has yielded some grim results so far in 2020
in terms of snow-water equivalent.
In letters addressed to Interior Secretary David Bernhardt and
Gov. Gavin Newsom, the Association of California Water Agencies
is urging state and federal officials to rejoin talks on
voluntary agreements to address ecosystem needs in the
Sacramento-San Joaquin Delta.
The Agribusiness and Water Council of Arizona likes to say it
represents Arizona agriculture “from ditch bank to dinner
plate” indicative of the fact that its members range from
farmers and ranchers to irrigation groups and trade
associations — all of them concerned about water flow along
the 1,450-mile-long Colorado River.
In her moving series, The Salton Sea, American photographer
Debbie Bentley documents the last days of a dying California
lake that used to be a popular holiday spot in the 1950s,

Following spring storms, the Bureau of Reclamation today issued
updated allocations for Central Valley Project contractors for
the 2020 contract year. … The allocation for south-of-Delta
agricultural water service contractors is increased from 15% to
20% of their contract total. Municipal and Industrial water
service contractors south-of-Delta are now allocated 70% of
their historic use, up from 65%, or health and safety needs,
whichever is greater.
Cornell engineers have used advanced modeling to simulate more
than 1 million potential futures – a technique known as

Over the past six months, scientists have been flying high over
the Pacific Ocean, into the stratosphere to study weather
phenomena called atmospheric rivers. These rivers in the sky
can deliver huge amounts of rain and snow to the west coast.
And they may be getting more intense. NPR’s Nathan Rott joined
them for a flight.
For Indians, confronting economic uncertainty and food
shortages has been part of life since Europeans arrived in our
lands. … This is why the Yurok Tribe is fighting so hard to
remove Klamath River dams and restore the salmon runs that have
fed our people since the beginning of time.
A 17-state coalition on Monday asked the U.S. District Court
for the Northern District of California to block the Navigable
Waters Protection Rule while they spar with government lawyers
over its legality. The Environmental Protection Agency and Army
Corps of Engineers published the rule in April, and it
officially takes effect June 22, tightening the federal
definition for the types of wetlands and waterways the Clean
Water Act covers.
The agreement between property owners, nonprofits and multiple
governmental agencies outlines a plan to remove the weir, or
low wooden dam at the mouth of the lagoon, and excavate the
entire 220-acre preserve to restore tidal flushing. … Without
intervention, the lagoon would continue to fill with sediment
and vegetation until it eventually disappears.
Increased frequency and severity of droughts threatens
California’s endangered salmon population — but pools that
serve as drought refuges could make the difference between life
and death for these vulnerable fish, according to a study by
researchers from UC Berkeley and California Sea Grant…
As forests in California and the Western U.S. are hit by rising
numbers of fires and disease outbreaks related to climate
change, some experts argue that using dead and diseased trees
to produce biomass energy will help to restore forests and
reduce CO2 emissions.
Foothill Yellow-legged Frogs have begun to spawn, laying small
snow-globe sized egg masses in streams and rivers. They are one
of the few stream-breeding frogs endemic to California and
Oregon. This species is a good indicator of stream health
because they link aquatic and terrestrial ecosystems and are
strongly tied to natural seasonal cues associated with local
On the same day Gov. Gavin Newsom announced $19 billion in
budget cuts to his 2020-2021 budget, two of California’s
environmental protection agencies filed a request to fund a
lawsuit against the Federal government over its boost in water
supplies sent to the San Joaquin Valley.
Northern California will have its most soaking rain from this
storm into Monday. Through Tuesday, with the cold upper-level

thunderstorms, some possibly with small hail, can be expected
in Northern California.
Sprawled across a desert expanse along the Utah-Arizona border,
Lake Powell’s nearly 100-foot high bathtub ring etched on its
sandstone walls belie the challenges of a major Colorado River
reservoir at less than half-full. How those challenges play out
as demand grows for the river’s water amid a changing climate
is fueling simmering questions about Powell’s future.
A new study led by Adam Schreiner-McGraw, a postdoctoral
hydrology researcher at University of California, Riverside,
modeled shrub encroachment on a sloping landscape and reached a
startling conclusion: Shrub encroachment on slopes can increase
the amount of water that goes into groundwater storage. The
effect of shrubs is so powerful that it even counterbalances
the lower annual rainfall amounts expected during climate
The Trump administration’s long-anticipated water jurisdiction
rule has already drawn a half-dozen legal challenges since its
April release, with more on the way. The Navigable Waters
Protection Rule narrows which types of wetlands and waterways
trigger federal Clean Water Act oversight, replacing
interpretations by Obama-era officials and earlier
administrations. … Here’s a breakdown of key legal arguments:
A water budget is an accounting of the rates of the inflows,
outflows, and changes in water storage in a specific area;
however, as simple as that might sound, developing an accurate
water budget can be a difficult and challenging endeavor. To
address this problem, the Department of Water Resources has
developed a water budget handbook…
For decades, sediment buildup in California’s Butano Creek
caused an array of issues for both fish and people. It flooded
roads and local communities, prevented steelhead and coho
salmon from migrating, and contributed to substantial die-offs
of fish. In October 2019, the NOAA Restoration Center and
partners finished a $7 million effort to remove the sediment
and restore the creek.
The Round Valley Indian Tribes, California Trout, Humboldy
County, the Mendocino Inland Water and Power Commission and

Gov. Gavin Newsom used his daily coronavirus briefing Thursday
to outline an austerity budget with deep cuts to cover a
massive $54.3 billion deficit. Newsom’s proposal includes major
cuts to environmental programs, including a $681 million slash
in spending for environmental protection compared to last year,
and a $224 million cut to the state’s natural resources
Water could soon be shut off to farmers in the Klamath Basin,
triggering major financial losses. Klamath Project farmers
began hiring, and ordering supplies based on Bureau of
Reclamation forecasts of 140,000 acre feet of water. Gene Souza
of the Klamath Irrigation District says that water allocation
The conflict over California water, often compared to a war,
rather resembles a geological process. As along an earthquake
fault, surface spasms come and go. The latest twitch is an
injunction momentarily halting some Trump Administration water
plans. But the underlying pressures are a constant. They never
stop exerting themselves.
In March, the California Department of Water Resources released
a nearly completed draft report on the risk of water shortage
in rural areas and the drought vulnerability of small systems.
… Across the state, Monterey County is among the most
vulnerable counties, with one of the largest numbers of highly
impacted rural communities, according to the report. Also, the
county’s small water systems are on average the 13th most
vulnerable out of those of 58 counties.
This year’s changes to the Clean Water Act have made the
already-challenging work of scientists and engineers in water
planning and management exponentially more difficult. Questions
abound, from jurisdictional issues to definitions and
classifications, as a result of the “Navigable Waters
Protection Rule,” which, among other things, removes federal
protections from ephemeral waterways.
A partnership of numerous Northern California agencies intends
to file an initial plan to acquire the Potter Valley project
from the Pacific Gas and Electric Co., multiple sources

of complex water infrastructure dividing the Eel and Russian
A new study published in Nature Climate Change indicates that
about 50 percent of current runoff comes directly from Sierra
snowmelt, and the Valley stands to lose between 13 percent and
50 percent of snowmelt runoff as the climate warms.
A spring storm had retreated inland during the night, leaving a
canopy of unbroken clouds over San Diego’s Mission Bay. About
20 engineering students and others gathered in the morning
chill to launch a cockeyed-looking vessel, mechanical guts
fully visible, into the still water.
The U.S. Environmental Protection Agency has proposed spending
$300 million to address the problem of toxic sewage flowing
across the border into San Diego County, legislators announced
Tuesday. The money would be part of the United
States-Mexico-Canada Agreement Implementation Act, and will be
used for the engineering, planning, design and construction of
wastewater infrastructure at the border, officials said.
As a result of compliance with conservation measures through
lower indoor water use, the amount of wastewater effluent was
reduced. This reduction means less water for recycling and
reuse — a source of water often thought of as drought-proof —
and less water for stream augmentation, with a consequence of
potentially impacting streamflow and downstream water
The return of drought to California has been widespread—58% of
the state now experiences some level of dryness, according to
the U.S. Drought Monitor—with extreme drought concentrated in
4% of the state, primarily in the northwestern region of
Siskiyou, Trinity and Humboldt counties.
The event was the first weather balloon launch from a Yuba
Water Agency site near Beale Air Force Base. But it will not be
the last. During atmospheric rivers, scientists plan to release
a balloon every three hours from this point to collect data.
And the more data, the better, because understanding the
structure of these storms can help with forecasting and flood
There is a better, more equitable pathway for reducing the
deficit without forcing arbitrary cuts. It involves 3 million
acres of irrigated agriculture, mostly alfalfa and forage
crops, which consume more than 80% of total water use in the
basin. By retiring less than 10% of this irrigated acreage from
production, we could eliminate the existing million acre-foot
overdraft on the Colorado River..
A $4.1 million contract for the long-awaited dredging of
Phoenix Lake reservoir, identified as necessary more than 15
years ago, has been awarded to Steve Manning Construction, Inc.
of Redding by the Tuolumne Utility District. … Phoenix is the
primary drinking water source for Sonora, Jamestown, Scenic
View, and Mono Village.
A judge issued a preliminary injunction in two lawsuits brought
against the administration by California’s Natural Resources
Agency and Environmental Protection Agency and by a half-dozen
environmental groups. The order bars the U.S. Bureau of
Reclamation until May 31 from going ahead with expanding the
amount of water it pumps from the San Joaquin Delta through the
federal Central Valley Project.
The Center for Biological Diversity petitioned today to protect
the Santa Ana speckled dace, a small minnow native to Southern
California streams, under the Endangered Species Act. Speckled
dace have been eliminated from three-quarters of their former
stream habitats in Southern California due to dams, water
diversions and urbanization.
Water is flowing through the heart of Bakersfield in the Kern
River and local water managers are shaking their heads in
disbelief and frustration. Except, that is, for Art Chianello.
Chianello is Bakersfield’s Water Resources Department director
and the man behind the healthy flow currently being enjoyed by
numerous residents as springtime temperatures heat up.
An ambitious plan to build the largest new reservoir in
California in 40 years to supply water to homes and businesses
from the Bay Area to Los Angeles, along with Central Valley
farmers, is being scaled back considerably amid questions about
its $5 billion price tag and how much water it can deliver.
Being born from an engineering miscalculation on the part of
the California Development Company means the Salton Sea has
been written off as an “accident” in histories inked on many
pages, ranging from The Washington Post to the Daily Mail. But
that framing is too simplistic, new research suggests, arguing
that the sea’s formation was inevitable, regardless of the
famous canal breach in 1905.
The Bureau of Reclamation and Friant Water Authority seek
public input on alternatives to repair a 33-mile stretch of the
Friant-Kern Canal in California’s eastern San Joaquin Valley.
This stretch of canal has lost over half of its original
capacity to convey water due to subsidence—a sinking of the
earth from groundwater extraction.

billion, is the largest in the history of Reclamation’s Dam
A strange thing happens during particularly wet winters in
California: farmers flood their fields. … Aquifers are the
last line of defense against drought conditions. By flooding
their fields in January, farmers hope to fill these underground
reservoirs with water they can use in August. If a trio of
recent studies prove accurate, one can expect to see this
method deployed more regularly.
For California, the findings could have positive ramifications
for the state’s struggling commercial and recreational salmon
fishing industry. In recent years, state and federal officials
have relied more and more on fish raised in hatcheries that are
hauled downriver via boat or in a truck. The hauling somehow
throws salmon GPS systems out of whack.
The University’s Adrian Harpold recently led a team in
developing a modeling tool to focus on the issue of water
quantity. The tool predicts how different approaches to
thinning the forest impact snowpack accumulation in Lake Tahoe,
which controls how much water is available for downstream
communities such as Reno.
Following passage of SGMA, The Nature Conservancy received a

As a Science Fellow placed in the California Natural Resources
Agency, I hear a lot about these snow surveys; however, it’s
one thing to read about the data and the program, and another
thing entirely to go outside and participate in sampling. It
was fascinating to survey the snow course and follow the same
techniques that surveyors have been using for decades to track
and manage the snow.
The survey data indicated that shotgun wads, the plastic piece
inside a shotgun shell that separates the shot from the powder,
are one of the top ten most commonly found plastic items on all
surveyed beaches. These shotgun wads likely come from waterfowl
hunting, year-round shooting ranges, and target shooting fields
along the San Francisco Bay and Delta.
Last week, environmental groups, states, and cities filed three
complaints in differing federal district court challenging The
Navigable Waters Protection Rule: Definition of Waters of the
United States, which was published in the Federal Register on
April 21, 2020, and is currently scheduled to become effective
on June 22, 2020.
Rather than soaking into the ground, the water is swept quickly
into rivers and streams where it increases flood hazards. But
how much of a hazard are these impervious surfaces? A new study
has estimated the size of the effect. For every additional
percentage point of impervious surface in a watershed — going
from 5 percent coverage to 6 percent coverage, for instance —
the peak of the highest flood flow of the year increases by 3.3

The Court decision introduces the concept of a “functional
equivalent of a direct discharge” as a guideline for when a
point source discharge must obtain a permit. It cites the case
of an injection well receiving pollutant discharge that then
travels a few feet through groundwater into navigable waters as
a clear case of “functional equivalent” to direct discharge.
Following poor rainfall this winter and rising water demand in
recent years, the Marin Municipal Water District is considering
a major purchase of Sonoma County water as insurance for a
potential dry period.
As expected, irrigators in the Klamath Project are getting less
water than they will likely need this summer thanks to a
combination of dry weather and more water being kept in-stream
to protect threatened coho salmon.
For the past decade, Kane County leaders have argued their
southern Utah community will need water piped from the Colorado
River to meet future needs, but the local water district
abruptly announced Thursday it was pulling out of the costly
Lake Powell pipeline project, leaving Washington County as the
only remaining recipient of the water.
Oregon Water Resources Director Thomas Byler sent a letter to
Reclamation’s Klamath Basin Area Office manager Jeff Nettleton
on Thursday, confirming it has taken exclusive charge of Upper
Klamath Lake… The order said it prohibits U.S. Bureau of
Reclamation from diverting stored water in Upper Klamath Lake
through Link River for purposes of a 50,000 acre-feet flushing
flow without a water right.
It wasn’t exactly a “March Miracle,” but the precipitation
Santa Barbara County received this spring rescued what
otherwise had been a fairly sorry rain season, and gave a
healthy boost to local water supplies. As of Monday, the county
as a whole had received 95 percent of its average rainfall to
date, according to the county Flood Control District.
When the Water Forum Agreement was officially signed 20 years
ago, the occasion marked an unprecedented show of regional
cooperation. For years, interests representing business, the
environment, water suppliers and others had sparred over the
water needs of people vs. the environment of the lower American
Over the past several months, the Authority has undertaken a
rigorous Value Planning effort to review the project’s proposed
operations and facilities in an effort to develop a project
that is “right sized” for current participants while still
providing water supply reliability and enhancing the
environment.The process has resulted in a project that includes
facilities and operations that are different than originally
The Supreme Court ruled on Thursday that the Clean Water Act
applies to some pollutants that reach the sea and other protected
waters indirectly through groundwater. The case, County of Maui
v. Hawaii Wildlife Fund, No. 18-260, concerned a wastewater
treatment plant on Maui, Hawaii, that used injection wells to
dispose of some four million gallons of treated sewage each
The Bureau of Reclamation, in coordination with PacifiCorp,
plans to increase flows below Iron Gate Dam to reduce the risk
of disease for coho salmon in the Klamath River. Starting
Wednesday, April 22, flows below Iron Gate Dam will increase
from approximately 1,325 cubic feet per second up to 6,000 cfs.
With the realization that California has decades worth of
opposition to building reservoirs on its record, it now makes
sense to take the dam application, submitted and approved by
them, to the federal government for help instead.
Pacific Gas and Electric Company (PG&E) announced that it
will be upgrading the Lower Bucks Lake Dam this year by
attaching a waterproof membrane to the upstream surface of the
dam to prevent seepage and extend the dam’s service life.
Publication starts a 60-day clock before the rule goes into
effect and waves a green flag for an onslaught of lawsuits
likely to be filed around the country. The litigation will
undoubtedly run beyond Election Day, so the future of the rule
likely depends on whether Trump wins a second term.
Lewis MacAdams, a poet and crusader for restoring the concrete
Los Angeles River to a more natural state and co-founder of one
of the most influential conservation organizations in
California, has died. He was 75.
Although it is clear that river discharge is the major source
of plastic pollution entering the oceans, there remains
uncertainty around how plastic pollution is transported through
rivers and coastal marine waters. How important is stormflow
for delivering plastic pollution from rivers to the coastal
ocean? How are microplastics transported through coastal
environments? How much is eventually sinking and settling on
Pulling the plug on the eve of Earth Day, the Environmental
Protection Agency eliminated critical pollution rules from the
Obama era that had safeguarded at-risk ecosystems and drinking
water across the country. The new Navigable Waters Protection
Rule, in the works since President Donald Trump’s inauguration,
was finalized Tuesday.
Today, the Bureau of Reclamation updated the water supply
allocation for Friant Division Central Valley Project contracts
for the 2020 contract year. The Friant Division provides water
for 15,000 family farms and several cities in the Central
Valley. … Given the current hydrologic conditions,
Reclamation is increasing the Class 1 allocation from 40% to
55%; Class 2 remains at 0%.
Now, just as the first Earth Day in 1970 gave U.S. policymakers
a chance to chart a fresh course for conservation, this year’s
50th anniversary offers lawmakers an opportunity to act on a
growing body of evidence that free-flowing, well-protected
rivers serve the greater public good.
California Attorney General Xavier Becerra filed a motion
Tuesday evening seeking to stop implementation of new Federal
environmental guidelines aimed at boosting water supplies for
the Central Valley and Southern California from the
Sacramento-San Joaquin Delta.
Counts of Chinook salmon in the Eel River were lower during the
2019 – 2020 ocean runs than any previous count conducted by the
Eel River Recovery Project since the organization began
tracking in 2012, according a new report, with estimates the
entire Chinook salmon run below 10,000 fish.
Under the drought contingency plan hammered out by Colorado
River Basin states last year, Arizona agreed to voluntarily
reduce its water use by 192,000 acre-feet, or about 7%, leaving
that water in Lake Mead to help reduce the likelihood of
greater cutbacks down the road. Tom Buschatzke, director of the
Arizona Department of Water Resources, says data from a new
Bureau of Reclamation report show that plan is working.
Two separate letters sent to President Donald Trump and members
of Congress highlight the importance of providing support for
enhancing water management, particularly in light of the
tumultuous conditions created by COVID-19.
It has been 30 years since the last time a dam was seriously
considered on the East Fork [of the Carson River] as a means to
reduce flooding and increase water for agriculture and other
uses. … The East Fork begins near the base of Sonora Peak in
California. The river’s upper gorge was carved out by a 16-mile
glacier coming off the 11,500-foot high mountain. It is one of
only two major free-flowing rivers in the Eastern Sierra.
The case was filed in late 2001, the year there was an
announcement that no water would be available for Klamath
Project irrigation from Upper Klamath Lake. The plaintiffs
claim that if the water is taken under the Endangered Species
Act, the fifth amendment of the U.S. Constitution requires
payment of compensation for the water right, a form of
property, that has been taken.
The whole San Francisco Bay ecosystem—that enormous estuary
with its maze of bays, rich delta, and associated rivers and
streams—is in the midst of an ecological calamity. Decades of
dam building and water extraction to quench the thirst of
California’s growing population and the needs of its mighty
agriculture industry have starved the state’s waterways, as
well as the bay itself, of crucial freshwater supplies. As a
result, the entire estuary is under enormous stress.
Voluntary agreements in California have been touted as an
innovative and flexible way to improve environmental conditions
in the Sacramento-San Joaquin Delta and the rivers that feed
it. … Yet, no one said it would be easy getting interest
groups with sometimes sharply different views – and some, such
as farmers, with livelihoods heavily dependent on water — to
reach consensus on how to address the water quality and habitat
needs of the Delta watershed.
Yolo Basin Foundation’s Board of Directors announced this week
that Chelsea Martinez has been named the Foundation’s new
executive director. … Martinez joined the Foundation in 2017
as the Community Outreach & Volunteer Coordinator and has grown
and sustained the Foundation’s volunteer base to over 200
volunteers as well as helped to increase community involvement
in its programs.
The U.S. Bureau of Reclamation released projections for the
Colorado River’s water supply for the next two years. … Lake
Mead is projected to fall into “Tier Zero” conditions for 2021
and 2022. That’s a new designation under the Drought
Contingency Plan which requires Arizona, Nevada and Mexico take
cuts in their water supply.
The US Bureau of Reclamation is to resume a seismic safety
modification project at Boca Dam near Truckee in California
today, following its seasonal closure in November 2019, with
social distancing guidelines recommended by the Centers for
Disease Control and Prevention and other COVID-19 precautions
to be followed during construction.
U.S. Representative T.J. Cox, Senator Dianne Fenstein and
Represenatives Jim Costa, Josh Harder and John Garamendi on
Thursday called on Interior Secretary David Bernhardt and Gov.
Newsom to come up with a coordinated effort to manage the State
Water Project and the federal Central Valley Project.
For the last four years, our team at UC Davis has been
conducting scientific studies on reintroduced spring-run
Chinook salmon in the San Joaquin River and we wanted to take a
minute to share some of what we’ve learned. Plus, everyone
loves a good comeback story right?
On March 13, 2020, water users in the Klamath Reclamation
Project (Project) petitioned the United States Supreme Court to
review the Federal Circuit Court of Appeals’ decision in Baley,
et al. v. United States, et al. (Baley). The decision denied
the water users’ takings claims for the 2001 Project water
shutoff on water law grounds.
President Donald Trump and California Gov. Gavin Newsom may
have set aside their incessant squabbling over most issues to
cooperate on the pandemic, but they are poised for showdown
over who controls the state’s vital water supply.
In the past decade, environmental groups have had success
bringing back patches of life in parts of the river delta. In
these green islands surrounded by the desert, water delivered
by canals and pumps is helping to nourish wetlands and forests.
Cottonwoods and willows have been growing rapidly. Birds have
been coming back and are singing in the trees.
The U.S. Forest Service has suspended controlled burns on
public lands in wildfire-prone California because of the
coronavirus pandemic, upsetting officials who see the program
as key to preventing seasonal infernos like those that
devastated parts of the state in 2018.
Officially, California’s most recent drought lasted five
painful years and ended in 2017. But a new study released
Thursday says California and the rest of the West are enduring
a continuing megadrought that ranks among the worst on record.
Record-breaking April rains eliminated all drought and abnormal
dryness from Southern California and up the Central Coast
through Monterey County, but drought has worsened in
northwestern California, the U.S. Drought Monitor said
Kristin Sicke is Assistant General Manager for Yolo County
Flood Control and Water Conservation District, which manages
water supplies for 200,000 acres in western Yolo County, which
encompasses Woodland, Davis, and the surrounding area. In this
presentation from the 2019 Western Groundwater Congress, Ms.

The Klamath River Renewal Corporation’s plans to remove four
dams on the Klamath River in the US has taken a major step
forward with the issuance of key documents from the California
State Water Board. The plan – the largest dam removal project
in the US – would re-open 360 miles of the Klamath River and
its tributaries to salmon.
A rare, wild green sturgeon was found on the San Joaquin River
upriver from the confluence of the Merced this past weekend by
U.S. Bureau of Reclamation crews checking salmon traps at Hills
Ferry. The discovery caused some excitement as this endangered
fish had not been seen that far up the San Joaquin in many
years, according to National Marine Fisheries Service staff.
The Metropolitan Water District of Southern California on
Tuesday voted to sue the state of California over a permit one
state agency granted to another at the end of March. The permit
is related to operations of the State Water Project, which
serves 27 million people and irrigates 750,000 acres of
The models show drought is expected to keep its hold over the
mountains along the New Mexico-Colorado border that feed the
Rio Grande, while California, Nevada and other southwestern
states aren’t likely to see a reprieve from dry conditions
Southern California Edison, the operators of the San Onofre
Nuclear Generating Station, is still investigating what caused
the release of 7,000 gallons of sewage into the ocean last
month but it appears the culprits were a blockage in the
facility’s sewage treatment plant and a worn out pump switch.
The U.S. Bureau of Reclamation announced a water allocation
update Monday and it had disappointing news for some San
Joaquin Valley farmers, as well as wildlife refuges. The San
Joaquin River Exchange Contractors saw their allocation cut
from February’s announced 100% to 75%, which is their contract
minimum. Wildlife refuges likewise were reduced from 100% to
How critical are Sacramento Valley floodplains for a vibrant
fishery? A California Fish and Game Bulletin from 1930 gives us
a clue. The report documents the Sacramento River commercial
salmon catch declining from 6 million pounds in 1918 to less
than 1 million pounds by 1927.
The state recently got a new permit for water delivery
operations from its wildlife agency. In the past, that kind of
authority came from adhering to federal rules. Now, with a
dispute between the state and federal government over water
management and endangered species act protections, the state
issued its own permit. Critics of the state’s move say they
plan to file lawsuits.
Without the river, there would not have been an Emigrant Trail
through this site, gold would not have been discovered in
Dayton and who knows when the Comstock Lode would have been
discovered and Nevada might not even be Nevada today!
Since March 10, the weather station on the University of
Southern California’s campus has seen just under seven inches
of rain, or nearly half of all taken in for the entire water
year. If that sounds like a lot for March and April, it is.
According to historic norms, the average rainfall during those
two months is 3.34 inches.
Our guests discuss what the WOTUS rule is and how it was
developed, what was formerly protected under the Obama era rule
and what water bodies and ecosystem services have lost federal
protection under the new rule. They also discuss whether state
level protections are sufficient and whether science backs the
new rule (it doesn’t).
Given the historical resources dedicated to monitoring and
studying striped bass in the San Francisco Estuary, the
question must be asked: Why don’t we know more about what
they’re doing in the Pacific Ocean?
The largest dam removal project in U.S. history came one step
closer to fruition this week, as California issued permits for
breaching the four dams on the Klamath River. The State Water
Resources Control Board issued a Clean Water Act certification
and environmental assessment for the proposal to remove three
dams in Northern California and one in southern Oregon.
The agreement pays Antioch $27 million, which guarantees that
they will be able to utilize its 150-year old water rights and
remain in the Delta for the long-term. The $27 million, in
addition to $43 million in State grants and loans, completes
the financing for the $70m Brackish Water Desalination Plant.
A lawsuit over the El Dorado Irrigation District’s plan to pipe
the Upper Main Ditch was denied by Superior Court Judge Dylan
Sullivan in a final ruling issued March 27. The lawsuit filed
by a Pollock Pines-based group called Save the Canal challenged
approval of the project and certification of the project’s

Southern Resident killer whales have long pursued the biggest
and most nourishing Chinook salmon from coastal Pacific waters.
Chinook salmon fishing is also a mainstay of the West Coast
economy, generating nearly $72 million in income last year. Is
there room for both? The answer is yes, with safeguards.
While the coronavirus is giving the planet’s environment a
respite from pollution, not all resources are getting a break.
Groundwater supplies, particularly in drier parts of the U.S.,
are being tapped more than ever by the enormous data centers
run by Microsoft, Google and other tech giants, which require
vast quantities of water for cooling and power generation.

Several Congressional leaders sent a letter to Governor Gavin
Newsom expressing disappointment in the decision to issue an
incidental take permit for long-term operations of the State
Water Project. … The letter was signed by Representatives
Kevin McCarthy, Devin Nunes, Ken Calvert, Tom McClintock, Doug
LaMalfa, and Paul Cook.
The $650 million project at Lake Mead was finished on time and
came in under budget, marking a big step in new infrastructure
that is critical in preserving reliable water delivery for the
valley. The pumping station holds a capacity to deliver 900
million gallons of water per day to two of Southern Nevada
Water Authority’s treatment facilities.
Farms and ranches in the Klamath Project will likely have far
less water during the 2020 irrigation season than they did a
year ago, with at least one forecast predicting water supplies
will be less than half of typical demand.
At the 2020 California Water Law Symposium, a panel discussed
the history of the project. Speaking on the panel was Chief
Caleen Sisk with the Winnemem Wintu Tribe, Doug Obegi with the
Natural Resources Defense Council, and Darcie Houck who is
currently General Counsel with California Energy Commission,
but formerly represented the Winnemem Wintu Tribe when she was
in private practice.
The water transfers could occur on an annual basis sending
water from willing sellers north of the Sacramento-San Joaquin
Delta to water users south of the Delta and in the San
Francisco Bay Area. Based on annual approvals, the transfers
could occur through 2024. In addition, the transfers could
occur by various methods, including groundwater substitution,
cropland idling, reservoir releases and conservation.
This report, “Scaling Corporate Water Stewardship to Address
Water Challenges in the Colorado River Basin,” examines a set
of key corporate water stewardship actions and activities, with
associated drivers and barriers, to identify how the private
sector could help tackle Colorado River water challenges.
According to the Washington Post’s fact checker, as of January,
2020, President Trump had made 16,241 false or misleading
claims during his first three years in office. Sadly, this lack
of regard for truth seems to be trickling down and infecting
the Trump Administration’s management of the federal Central
Valley Project in California, one of the largest water storage
and diversion projects in the country.
Taking advantage of recently approved rules, the federal
government is quickly following through on President Donald
Trump’s promise to quiet environmentalists and “open up the
water” to California farmers. … The pumps in the south of the
Sacramento-San Joaquin River Delta aren’t just whizzing during
what will likely end up being classified a “critically dry”
hydrological year, they are churning — and killing — endangered
salmon during a critical migration period.
In the century-long “us-versus-them” mentality of California
water, a plan released by Gov. Gavin Newsom’s Department of
Water Resources last week achieved something perhaps never
accomplished before in the Golden State’s water industry. It
incited universal scorn.
The State Water Board today issued key documents that move the
Klamath River Renewal Corporation significantly closer to
removing four dams and re-opening 360 miles of the Klamath
River and its tributaries to imperiled salmon.
Stormwater is the rain and other water that runs off of streets
and sidewalks into nearby gutters or waterways. Communities
throughout the western U.S. are expanding efforts to collect
this valuable water resource. These projects range from
capturing water from a single rooftop or driveway to developing
large infiltration basins that recharge billions of gallons of
water each year in groundwater basins.
In a recent announcement from the U.S. Bureau of Reclamation
(USBR), Friant Division contractors will be receiving an
increased water allocation. USBR has doubled the Class 1
allocation to 40 percent for Friant Division Central Valley
Project contracts for the 2020 contract year.
An analysis led by Stanford University found that temperatures
rose about 1.8 degrees Fahrenheit statewide while precipitation
dropped 30% since 1980. That doubled the number of autumn
days—when fire risk is highest—with extreme conditions for the
ignition of wildfires.
A slow-moving storm system will bring more rain and mountain
snow to parts of California through Thursday, and could trigger
flash flooding in the Mojave Desert, including some of
America’s typically driest places.
Unprecedented efforts by leaders at the state and national
level have led to the kind of cooperation that will provide
valuable benefits to water users and the environment. I know
because that’s what we’ve been doing in the Sacramento Valley
for many years. The kinds of success we’ve achieved can be
replicated in other parts of the state.
An empty lot on a 70-foot-high bluff above the ocean seemed
like the perfect place to build a house when the owners bought
the parcel for $1.8 million. Now a state ruling means they’ll
have to put the house farther away from the water, where they
won’t see the shore. It’s a result of climate change and
California’s response to it.
Today, responding to a global pandemic is every governor’s top
priority. When we emerge from this crisis, Gov. Gavin Newsom
will face a challenge to ensure California’s future economic
and environmental health. In this context, his water policies
will represent critical decisions.
The Los Angeles River is special to Ed Reyes, who considers it
an integral part of his childhood. Reyes, 60, the executive
director of River LA and a former Los Angeles City councilman,

The Wildlife Conservation Board has approved approximately
$24.3 million in grants to help enhance flows in streams
throughout California. … The approved projects will lead to a
direct and measurable enhancement of the amount, timing and/or
quality of water in streams for anadromous fish or special
status, threatened, endangered or at-risk species, or to
provide resilience to climate change.
At the 2019 Western Groundwater Congress, Gilbert Barth, PhD,
