As a professor of civil and environmental engineering at
Stanford, as well as director of a National Science Foundation
center to re-invent urban water supply (known as ReNUWIt),
Richard Luthy he has spent decades studying the state’s
metropolitan areas. In a new journal article, he argues that
California cities can no longer rely on their three traditional
water-coping strategies: over-drafting groundwater, depleting
streams and importing water from far away.
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.
Despite its reputation as a conservative owner, the
Metropolitan Water District of Southern California is piloting
a bold new initiative to produce an additional regional water
source through its Regional Recycled Water Program, which aims
to take treated sanitation water and purify it to produce
high-quality drinking water. … The $3.4-billion plan could
produce up to 150 million gallons of purified water daily,
addressing the needs of more than 500,000 homes and industrial
facilities.
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.
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.
When the Los Angeles Better Buildings Challenge award was
presented April 29, city officials credited Scottsdale-based
Dynamic Water Technologies for saving more than 1.5 million
gallons, or 20%, of annual water usage and reducing sewer
discharge by 85% in the 530,000-square-foot city hall building.
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…
Unlike water production wells, monitoring wells do not remove
groundwater, but instead use one or more small diameter pipes
placed anywhere from 50 feet to 2,000 feet deep. The pipes
house electronic equipment that continuously measures
groundwater level information. Groundwater samples can also be
manually collected from these wells to check for water quality.
My colleagues and I worked with Assemblymember Rudy Salas
(D-Bakersfield), to craft AB 2642, which will create the
Multibenefit Land Conversion Incentive Program… This new
program will provide incentive payments to farmers and
landowners who voluntarily repurpose their agricultural land to
other less water-intensive uses for a minimum of 10 years.
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.
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
quality…
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..
Dr. Aliashgar ‘Ali’ Montazar, a University of California,
Riverside researcher, heads up irrigation and water management
in Imperial and Riverside counties for the University of
California Cooperative Extension system. … He’s kicking the
tires for growers so they can decide if drip is the way to go
even in crops that traditionally haven’t had drip. And he’s
finding it has benefits beyond conserving water.
A new article by the U.S. Geological Survey (USGS) calls
efforts to mitigate land subsidence in the Coachella Valley “an
emerging success story,” a finding that is echoed by analysis
completed by local water agencies.
In principle, evaluating the adequacy of these plans to achieve
sustainability should also be simple: Does the anticipated
reduction in pumping plus increase in recharge equal or exceed
the basin’s long-term rate of overdraft? In practice, however,
it’s not so simple.
New research shows that carbon capture and storage (CCS) could
stress water resources in about 43% of the world’s power plants
where water scarcity is already a problem. Further, the
technology deployed in these water-scarce regions matters, and
emerging CCS technologies could greatly mitigate the demand CCS
places on water consumption.
Following passage of SGMA, The Nature Conservancy received a
$1.8 million Conservation Innovation Grant from USDA’s Natural
Resources Conservation Service to develop the Fox Canyon Water
Market. TNC, supported by project partners Fox Canyon
Groundwater Management Agency and California Lutheran
University, sought to establish a market-driven approach to
reduce groundwater pumping.
The Bureau of Reclamation has released a funding opportunity
for communities to take a proactive approach to drought through
building projects that increase water supply reliability,
improve water management, or provide benefits for fish,
wildlife and the environment.
Work to restore a damaged 9-foot diameter water pipeline in
Moreno Valley continued Monday, May 4, and outdoor watering
restrictions will be lifted for Western Municipal Water
District customers starting Tuesday. … The reduced-use
directive had been in place since Thursday after a contractor
punctured the Santa Ana Valley Pipeline.
The reduced-use directive was put in place after a contractor
punctured the 9-foot-diameter Santa Ana Valley Pipeline on
Thursday. The water flow in the line has been stopped while
repairs take place, and the moves by the districts were to help
ensure reserves are not depleted.
There are 29 federally recognized tribes across the Colorado
River Basin. Together, these tribes have water rights to
roughly 20% of the water that flows through the river annually.
In Arizona, the Colorado River Indian Tribes (CRIT) and the
Gila River Indian Community (GRIC) were critical partners in
making the Drought Contingency Plan possible.
Emergency repairs to a state-operated water pipeline prompted
officials Friday morning to ask 250,000-plus customers in
Moreno Valley and western Riverside County communities to
immediately stop outdoor water use. … Customers were asked to
not water plants or grass, wash cars or fill pools until
repairs on the Santa Ana Valley Pipeline, which brings water to
the region from Northern California, are completed, the MWD
said.
The Mojave Water Agency is looking for residents to produce
creative home videos that will deliver an important message
about water conservation. A $200 Visa gift card will be awarded
for first place, with a $100 card going to second place and $50
for third place, agency officials said in a statement.
Fairness – or at least the perception of fairness – could play
a determining role in the future of California’s groundwater,
according to new research. The study, published in Society and
Natural Resources, evaluated 137 surveys of Yolo County farmers
to gauge their perceptions of fairness for groundwater
allocation strategies and dispute resolution options.
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.
As of March, the East Valley Water District’s Sterling Natural
Resource Center construction project reached the halfway point
to scheduled completion⎯about 18 months in and 18 months left
to work. The water recycling plant will be capable of treating
up to 10 million gallons per day, depositing the clean water
into percolation ponds in order to recharge the Bunker Hill
Basin groundwater.
As Siskiyou County slips back into severe drought, members of
Siskiyou County’s Groundwater Advisory Committees met last week
to continue drafting groundwater management plans as
conservation groups, farmers and other special interest groups
brace for another dry summer.
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
River.
The Pajaro Valley Water Management Agency has been working
toward sustainable management of the Pajaro Valley’s water
resources. At the 2019 Western Groundwater Congress, General
Manager Brian Lockwood discussed the projects and programs the
Agency is implementing as they work towards achieving
groundwater sustainability.
The US Drought Monitor update released Thursday morning lists
far Northern California as the most impacted by a lackluster
rain and snow season. Some areas such as Eureka and Mount
Shasta are down more than 15″ of rain from their averages for
the season so far.
To develop the rankings, the state took into account numerous
factors, including each water system’s vulnerability to climate
change and projected temperature changes, projected sea level
rise, recent water shortages, whether the system is in an
overdrafted groundwater basin or was located in an area with
underlying fractured rock.
Samantha Ying and Michael Schaefer, both from the Department of
Environmental Sciences at University of California (UC)
Riverside, are part of a team set on untangling the mystery of
a practice upon which farmers have relied for centuries to
reduce water use—cover crops.
In January, water users in 21 critically overdrafted basins
delivered their groundwater sustainability plans to the state
Department of Water Resources. In this series, we examine the
36 plans submitted for 11 critically overdrafted basins in the
San Joaquin Valley—California’s largest farming region, where
excess pumping is a major challenge.
California’s 410 urban water suppliers will be required to
report monthly use and conservation data to state regulators,
under a resolution the State Water Resources Control Board
passed Tuesday. The vote makes permanent a voluntary program
that dates back to California’s devastating 2012-2016 drought.
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.
From the safety of their coronavirus shelters, the water
warriors of the Monterey Peninsula carry on the fight, and so
can you. … The environmental merits of removing the local
water system from private ownership and placing it under the
control of a government agency will be discussed in a virtual
public scoping meeting on April 21 at 5pm, via Zoom video
conference.
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.
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 Southern Nevada Water Authority is ending a decades-long
effort to build a controversial 300-mile pipeline to pump rural
groundwater from eastern Nevada to Las Vegas. On Thursday
afternoon, the water authority confirmed in a statement that it
would not appeal a recent court ruling that denied the agency a
portion of its water rights.
The Department of Water Resources has released a draft report
with recommendations and guidance to help small water suppliers
and rural communities plan for the next drought, wildfire, or
other natural disaster that may cause water shortages.
Local agencies in the most depleted groundwater basins in
California spent months putting together plans to show how they
will achieve balance in about 20 years. Now, after submitting
those plans to the state in January, groundwater sustainability
agencies (GSAs) must figure how to pay for them.
If you’re a Central Valley farmer and haven’t yet been hit up
by someone about reusing crummy water for irrigation — just
wait. Companies are springing up all over with the latest gizmo
they believe will take nasty, salty water, mostly from shallow
aquifers on the valley’s west side or oilfield produced water,
and make clean “new” irrigation water.
Eric Averett is General Manager with the Rosedale-Rio Bravo
Water Storage District, which is one of several water districts
within Kern County. … In this presentation from the Western
Groundwater Congress, Mr. Averett discusses how his district
and Kern County have been grappling with how to establish
groundwater pumping allocations.
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

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.
More than three dozen atmospheric rivers made landfall on the
West Coast from fall through early spring, but a lack of strong
events in California led to the development of drought
conditions in parts of the state.
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 time when many people in the world are inside their houses
to stop the spread of covid-19, it is easy to forget that good
news still exists. The Environmental Protection Agency’s
National Water Reuse Action Plan is a bit of good news. The
Plan, announced on February 27, 2020, by EPA Administration
Andrew Wheeler, prioritizes the use of recycled water.
In January, water users in 21 critically overdrafted basins
delivered groundwater sustainability plans to the state

What does a Central Valley almond farmer have in common with a
San Diego homeowner? The answer is simple: Water. More
specifically, the amount of water they need to sustain their
respective lifestyles — which is a lot.
At the 2019 Western Groundwater Congress, Gilbert Barth, PhD,
provided quantitative assessments of groundwater resources to
address questions associated with water planning, and
specializes in model development and calibration with a focus
on quantifying changes between surface water and groundwater
systems. He’s developed and applied models throughout the
Western US for regional, interstate, and international
deliberations.
Snow surveyors will head into the Sierra on Wednesday to take
the most important measurements of the season. … Statewide,
the snowpack and the water it holds is just 53% of average,
according to the daily report on the California Data Exchange.
While many residents across the US may want a traditional patch
of green carpet, Jodie Cook, a landscape designer from San
Clemente, California, explained over email that West Coast
homeowners are growing increasingly aware of how innovative
models for lawns can benefit natural ecosystems, while
providing a new dimension to the family home.
The Indian Wells Valley Groundwater Authority signed off on an
ordinance and related resolution officially requiring all major
pumpers needing metering on all groundwater extraction
facilities and pumps during a board meeting on Thursday.
While snow cover has increased thanks to a series of March
storms, the Northern Sierra 8-Station Index stands at 56% of
normal for the season. As of March 24, another 29.25 inches
would be needed to reach the season normal of 54.52 inches. But
the area normally gets just 9.42 inches from March 24 through
June 30. So a daunting 310% of normal precipitation would be
required to make up the deficit, according to Jan Null of
Golden Gate Weather Services.
After a very wet and snowy early 2019, which pumped up the
state’s reservoirs, California has averaged less than half of
average precipitation and snowpack so far in its rain year
Evapotranspiration data has historically been limited in scope
and expensive to access. A new project seeks to change that.
Researchers from NASA, the Desert Research Institute and the
Environmental Defense Fund, with support from Google Earth

The report by David Sunding and David Roland-Holst, professors
at University of California, Berkeley, estimates that one-fifth
of cultivated farmland in the San Joaquin Valley will be
permanently lost as groundwater plans take hold and water
supplies are severely restricted.
“Water management is one of the most important farming
practices you or your clients should be practicing, full stop,”
wrote Phoebe Gordon, UC Cooperative Extension orchard systems
advisor in Madera and Merced counties. Born and raised in
California, Gordon is excited to share her knowledge with
growers to improve orchard production and sustainability in the
San Joaquin Valley and beyond.
The Infrastructure Retrofit Project would mitigate earthquake
hazards currently threatening the Redwood Valley County Water
District and protect infrastructure against significant damage
in the future. The 2017 Redwood Complex fire also destroyed
parts of the water infrastructure in the valley and increased
the need for the reconstruction project.
The changes in groundwater levels in this report illustrate how
groundwater changes over time based on hydrologic conditions. A
one-year comparison of groundwater levels provides information
about the short-term effects of a single wet or dry year, while
a multi-year comparison of groundwater levels provides
information about trends in groundwater storage. Groundwater is
an important component of water budgets throughout the state

The most recent U.S. Drought Monitor released Thursday shows
that although recent rains have provided some relief for
Southern California, Northern California remains locked in
moderate drought or abnormally dry conditions.
David Orth is the principal of New Current Water and Land,
which offers strategic planning, program implementation, and
water resource development services. At the California

When county Board of Supervisor member Peggy Judd asked former
Gov. Bruce Babbitt to share his thoughts on rural counties
taking on responsibilities relating to groundwater management,
he responded, “I couldn’t say no.”
I remember being surprised when attending a local Groundwater
Sustainability Agency meeting and I first saw a schematic that
visually depicted the various levels of groundwater underneath
one of the Central Valley’s numerous subbasins.
Researchers with the University of Nevada, Reno, have been
working to evaluate and commercialize crops that use less
water. Professor John Cushman and his team think they’ve found
an alternative. It’s called teff.
Now, Big Ag and the water agencies that do its water will want
to also divert streamflow during the winter wet season. For
folks who believe that any water “diverted” to the ocean is
wasted water, winter storm and snow-melt high flows have become
the target.
While the first draft of the governor’s draft Water Resilience
Portfolio wasn’t the transformational vision many had hoped it

Former Gov. Bruce Babbitt is speaking out about widespread
problems of excessive groundwater pumping in rural areas of
Arizona, saying the state Legislature should give counties and
communities the power to protect their rapidly declining
aquifers. Babbitt appealed for action during a visit this week
to the Willcox area, where heavy pumping for farms has led to
falling water tables and left a growing number of families with
dry wells.
To the extent that new science requires new approaches in the
Delta, existing new science indicates that restoration of the
Delta will require more water to be left in the Delta, not
less.
The case, titled Baley v. United States, was filed 19 years ago
when the U.S. Bureau of Reclamation re-allocated Klamath River
irrigation water to threatened and endangered species. A
favorable outcome would mean upwards of $30 million
collectively in compensation for irrigators named in the case.
“It’s a huge problem, especially in the cities,” said Daniel
Tartakovsky, a professor of energy resources engineering at
Stanford University in California. Tartakovsky and his former
student Abdulrahman Alawadhi from the University of California,
San Diego have proposed a way to improve a traditional method
of detecting these leaks.
Given the wide swings in the availability of State Water
Project water from year to year as well as the possibility of
even more severe and lasting droughts, the San Bernardino
Valley Municipal Water District hired The Rand Corporation to
independently analyze the long-term demand forecasts of local
waters.
Stanford researchers have developed a machine learning model
that detects unexpected water-use consumption patterns – data

infrastructure needs around the state and helping to determine
the state role in rehabilitating that infrastructure.
San Joaquin Valley farmers say they hope a newly released
report will capture the attention of Californians about the
potential impact of water shortages in the region. The report,
released last week, said water shortages could cause 1 million
acres of San Joaquin Valley farmland to be fallowed and cost as
many as 85,000 jobs.
In a part of the country where freshwater supplies are often
scarce, the Olivenhain (California) Municipal Water District is
doing its part. The 4S Ranch Water Reclamation Facility
recycles some 1 million gallons of high-quality effluent each
day for irrigation and shares even more with neighboring
communities.
The largest reservoir in the Western U.S., Lake Mead, is rising
again after more than a decade of decline, and at least some

If agriculture in the valley is going to survive, water leaders
need to get cozy with new ideas and new allies. And, yes, that
means environmentalists.
The organizers of camp residency programs Space Saloon and
Designers on Holiday have announced the launch of DeSaturated,
an eight-day design-build festival in California’s Cuyama
Valley, a two-hour drive north of Los Angeles. With the rugged
high desert landscape as its backdrop, the
“community-in-residence” program will draw attention to the
state’s water scarcity.
An important new study finds that irrigated crop production
accounts for 86 percent of all water consumed in the western US
— and of all the water used on western farms, by far the
largest portion goes to cattle-feed crops such as alfalfa and
grass hay. To alleviate the severe shortage of water in the
region, study authors suggest rotational fallowing farmland
could be a simple and affordable means of dramatically reducing
water use in the region.
If you followed the news about the Colorado River for the last
year, you’d think that a political avalanche had swept down
from Colorado’s snow-capped peaks and covered the Southwest
with a blanket of “collaboration” and “river protection.” I
won’t call it fake news, but I will point out errors of
omission.
The Cuyama Valley is the driest agricultural region in the
county; the valley floor gets just a little more rain than the
Sahara. Yet for the past 75 years, this high desert region has
been a mecca for water-intensive farming on an industrial scale
— first alfalfa, and now carrots, a $69 million annual crop.
… Now, to the rescue — belatedly — comes the state
Groundwater Sustainability Act of 2014…
One day after President Trump tweeted his support, Senate
Majority Leader Mitch McConnell (R-Ky.) is expected to take
steps today to bring to the floor legislation that would
permanently fund the Land and Water Conservation Fund and
address the national parks maintenance backlog, senators said.
… Trump’s tweet was an election-year about-face from his
latest budget proposal, which recommended virtually eliminating
the popular, bipartisan program.
California’s Sustainable Groundwater Management Act of 2014 is
now “the law of the land (state)” and as such there will be
restricted agricultural groundwater pumping throughout the San
Joaquin Valley…
Forecasters and water managers keeping a close eye on
precipitation are hopeful that a wet month, a phenomenon known
by weather experts as “miracle March,” may help bolster
lackluster winter rain totals.
In 2019, California’s use of the Colorado River—a major water
source for Southern California’s cities and farms—dropped to
the lowest level in decades. We asked John Fleck—director of
the University of New Mexico’s Water Resources Program and a
member of the PPIC Water Policy Center research network—about
the ongoing changes in California’s use of this water, and what
it means going forward.
A judge on Thursday granted a six-month extension for roughly
14,000 Ojai Valley and Ventura property owners facing a
potential water adjudication. In January, the city of Ventura
sent thousands of legal notices and summonses to people with
property near the Ventura River or one of the area’s
groundwater basins.
In criticizing California for how it has managed its water
supplies, President Donald Trump falsely said that residents
“very shortly” will “get 50 gallons” of water to use a day.
That’s a distortion of two state water laws, which set
efficiency targets for water agencies, not individuals.
A major contributor to the Southern California water supply is
the Colorado River, which pumps in about 26 percent of the
region’s water supply via the Colorado Aqueduct, which was
built in the 1930s. … There’s a problem, and it’s happening
at the source. Years of multiple water allocations and
persistent drought have put the Colorado River under stress.
Northern California has just concluded one of its normally
wettest months without a drop of rainfall. Even with an extra
day on the calendar, February – a month that usually brings 20%
of San Francisco’s annual rainfall – just added to the streak
of dry days dating back to late January.

The idea was that people living in Mediterranean-type climates
(moist winters and dry summers) should landscape with plants
suited to dry landscapes rather than plants that need lots of
water to survive… Unfortunately, the term “xeriscape” quickly
became synonymous with austere landscapes.
When the top official overseeing the Environmental Protection
Agency’s WaterSense program first heard President Donald
Trump’s rant about toilets that must be flushed a dozen times
and modern faucets that provide only drips of water, she was at
a loss for words.
The Central Valley is America’s fruit bowl, and the heart of
California’s $50bn agriculture industry. But the 2011-2017
drought raised serious questions about the future of that
industry and forced the state to grapple with regulating the
one thing fueling much of it: groundwater.
Two bills that would make it easier for state regulators and
county officials to limit well-drilling and groundwater pumping
have died in the Arizona Legislature despite support from
lawmakers and pleas from county officials who are asking for
help to protect their rapidly declining aquifers.
Drought has expanded to nearly a quarter of the state, mainly
in central California, the heart of the state’s agricultural
sector, according to a U.S. Drought Monitor map made public
Thursday. The map shows 70 percent of the state is abnormally
dry.
Climate change has dramatically decreased natural flow in the
Colorado River, jeopardizing the water supply for some 40
million people and millions of acres of farmland, according to
new research from the USGS. The decline is expected to continue
unless changes are made to alleviate global warming and the
impacts of drier, hotter temperatures.
Oceanside celebrated the start of construction Wednesday on a
project that could make it the first city in San Diego County
to be drinking recycled water by 2022. At least two other
cities or water districts are close behind on similar projects,
and several more agencies are considering plans to make potable
recycled water a significant portion of their supply.
This is an approximate 24% reduction in residential water use,
and a 7% reduction for non-residential water use from today’s
levels. This will be implemented through the existing permit
review process and any project that requires a building,
grading, or discretionary permit and would result in more than
500 sq/ft new irrigated landscaping (ex. permitting for new
addition, new garage) would be subject to this water allowance.
What’s scarier than a malevolent clown under your bed? More

California is doing more to preserve its groundwater levels
than ever before, but a new, interactive tool by a local water
advocacy group suggests it may not be enough. Last Wednesday,
Visalia-based Community Water Center … argued that California
will experience longer, more severe droughts due to climate
change.
The Colusa Groundwater Authority, the California Department of

Marking a historic moment for the city of Oceanside and the
region, city officials and water industry leaders will break
ground on Pure Water Oceanside on Wednesday, Feb. 19 at 10 a.m.
at the San Luis Rey Water Reclamation Facility. Scheduled to be
completed before the end of 2021, Pure Water Oceanside will be
on the map as the first operating recycled water project in San
Diego County.
Water supply concerns, regulations, labor issues, tariffs,
climate change, and other challenges have prompted some rather
dire predictions about the future of California agriculture. We
talked to Dan Sumner—director of the UC Davis Agricultural
Issues Center and a member of the PPIC Water Policy Center
research network—about his research on California agriculture
in 2050.
The National Weather Service tweeted satellite images of the
Sierra on Tuesday, showing the stark difference between this
year and the above-average snowfall from 2019. The mountain
snowpack — a crucial element in the state’s annual water supply
— is 53 percent of normal for this time of year, according to
the Department of Water Resources.
David joins me today to discuss the water economy and where we
are right now as a civilization. He shares why we should be in
a global state of panic and why we’re no longer in a world
where water is sustainable. He explains the need for water to
be priced and how it can positively affect the ag industry.
David also discusses water rights, “free water,” the water
market, and possible solutions to water scarcity.
While the Arizona Legislature considers how to respond to
problems of falling groundwater levels in rural areas, the
agriculture industry is pushing back against proposals that
would require owners of large wells across the state to measure
and report how much water they’re pumping.
New federal data show that California may be sliding back into
drought, just as the Legislature is starting to pursue ways to
make sure residents are prepared for water shortages. Due to
weeks of dry weather about 10 percent of California and more
than half of Nevada are in drought mode, the federal government
reported Thursday.
As the county reports advances in water protection and
conservation technologies, water use continues to remain lower
that previous years, the Santa Cruz County Water Resources
Management Status Report shows.
City staff recommends Pleasanton sign on to a potentially $1
million task order with three other Tri-Valley public water
agencies for preliminary studies and community outreach … to
explore the possibility of supplementing the local water supply
with recycled water treated for drinking purposes, better known
as potable reuse water.
This rain-year has brought an alarmingly dry winter in
California so far, according to climate change experts. Now,
there’s a new tool to help Californians navigate your water
supply. It’s an online tool that allows a person to see the
groundwater levels in their area. The tool then gives a
representation of what could be at risk or impacted if a
drought hits.
By the most conservative estimate, 500,000 acres of agriculture
land are expected to go fallow in the San Joaquin Valley as
SGMA is implemented over the next 20 years, [David] Orth said,
while some studies say it could be as much as 1 million acres.
Since this process is just starting in the Sacramento Valley,
it’s unclear how the area might be impacted, but in general,
north of the Delta is in better shape.
Both Republicans and Democrats are backing measures in the
Legislature that would enable Arizona to start measuring how
much groundwater is pumped in unregulated rural areas where
aquifers have been rapidly declining.
First things first: you’d be wise to forget everything you’ve
read or heard recently about “voluntary agreements,” which
according to the usual suspects, will bring a just and peaceful
end the seemingly never-ending battle over California water.
Not true. Not even close.
California is stuck in a dry spell amid what is historically
the wettest time of the year. But while the Sierra snowpack is
dwindling and rainfall totals are below normal, weather
watchers are not concerned about a drought. “One dry year
doesn’t make a drought,” said Chris Orrock, a spokesperson for
the California Department of Water Resources.
One of the top priorities outlined in the Newsom
Administration’s recently released draft Water Resilience
Portfolio is reducing reliance on any one water source and
diversifying supplies – key strategies for making our water
supply systems more flexible, adaptable, and resilient to the
impacts of climate change.
Jan. 31 marked a major milestone for building groundwater
sustainability and climate resilience into California’s complex
and increasingly stressed water systems. It was the first major
planning deadline for implementing the state’s historic
Sustainable Groundwater Management Act.
Diaz Lake and the Laws Railroad Museum will be getting some
major fixes to their water systems, thanks to an anticipated
$400,000 in Prop. 68 Per Capita funds.
The Ventura City Council announced Monday that it may request a
six-month extension from the court for the thousands who were
sent legal notices or served with a court summons in the case.
… The litigation dates back to 2014 when Santa Barbara
Channelkeeper filed a lawsuit alleging the city of Ventura
was taking too much water from the Ventura River,
hurting habitat for steelhead trout and other wildlife.
Lawmakers in Arizona have proposed a new bill that would
require toilets, faucets and other plumbing fixtures sold in
the state to work more efficiently in an effort to save water.
… If passed into law, HB 2737 would emulate rules in states
like Texas, Colorado, California, Oregon, and New York state
that all require WaterSense certified fixtures in all new
construction.
The San Diego County Water Authority’s Board of Directors
visited the Imperial Valley January 30 for a day-long tour that
highlighted areas critical to the agency’s Regional Conveyance
System Study.
Vast amounts of valuable energy, agricultural nutrients, and
water could potentially be recovered from the world’s
fast-rising volume of municipal wastewater, according to a new
study by UN University’s Canadian-based Institute for Water,
Environment and Health.
On the heels of a seemingly perpetual drought that has slowed
surface water deliveries to a trickle and made water transfers
complicated and expensive, Joe Del Bosque and other growers
face new pumping restrictions under the Sustainable Groundwater
Management Act. … The farm’s water costs have already more
than doubled in the past 10 years…
Kiara Nirghin, ’22, developed a unique polymer that can keep
crops hydrated during dry spells. The innovative research has
garnered her global recognition, including top honors at the
Google Science Fair.
People crowded into an Ojai junior high school auditorium
recently after thousands received legal notices or a court
summons from the city of Ventura. The city notified 14,000-plus
property owners in the Ventura River watershed of a potential
adjudication of water rights. That move came years after the
city faced legal action over its own water use.
Large lawns and backyard pools were once common features of new
homes in the Phoenix area, but not anymore. A recent study of
single-family homes in the Phoenix metropolitan area showed
that nearly two-thirds of homes do not have a swimming pool.
The Santa Monica City Council approved a water self-sufficiency
plan Tuesday that will double the price of water and wastewater
removal by 2024. The rate increases will finance about $42
million in infrastructure projects that will allow Santa Monica
to stop importing water from the Metropolitan Water District of
Southern California by 2023.
Trump’s frequent allusions to a bygone era filled with superior
appliances misses what is largely a story of American ingenuity
and continued progress. Several manufacturers and trade groups
said these items work better than ever today — while also using
less water and power, the result of years of corporate
investment and testing. Industries that might normally cheer
reduced regulation say they don’t want government efficiency
standards eased.
Formally called a Direct Recirculating Apparatus Firefighting
Training & Sustainability (DRAFTS) Unit, the pump pod is a
self-contained unit that recirculates water used during
firefighter training and pump testing.
As I watch the way Governor Gavin Newsom is handling water
policy, I have two thoughts. First, the governor is on a track
that seems driven by adherence to some of Governor Jerry
Brown’s worst water policies. And, second, he’s not getting
good advice.
For many businesses in drought-ridden states like California,
water supply issues aren’t a problem for the future—they’re
happening right now. … For the Cloverdale-based Bear Republic
Brewing Company, the impact was especially devastating, due to
the city’s heavy reliance on the water supply of the Russian
River.
Time and time again seemingly well-intentioned initiatives and
repeated attempts to develop a comprehensive water management
solution have failed, despite cautionary tales. However, 2019
witnessed the horizon of a new initiative called the Voluntary
Agreements that could do what few, if any, past plans, efforts,
or reports could do – unite water management and develop
collaboration.
Despite growing concerns of a below-average rainfall season,
the city of Ontario revoked mandatory conservation measures
this week, setting a 0% water conservation target with state
regulators. … The City Council approved the change from
mandatory Stage 2 water conservation to voluntary conservation
on Tuesday, Jan. 21.
If President Trump wants to understand the risk of rolling back
water efficiency standards that have been in place for almost
30 years, he can turn to a member of his own Cabinet.
Agriculture Secretary Sonny Perdue has signed off on
regulations that treat water-efficient toilets and shower heads
as effective tools to save Americans from droughts and other
risks.
A single almond takes about three and half litres of water to
produce. Most almonds – an estimated 82 per cent – are grown in
drought-afflicted California, where it constitutes a
multibillion-dollar industry. The number of almond orchards has
doubled in the last 20 years in California.
Demand for water from 2002-2015 was down 36%, and demand for
2019 was only about half of what it was for 2015, city staff
said at a planning commission meeting Jan. 22.
New state-of-the-art water meters that will provide accurate,
real-time readings of how much water Lathrop’s residential
customers use are on the way. The Lathrop City Council approved
a consent calendar item that will allow city staff to purchase
the remaining 3,506 water meters in the city that have not yet
been updated – approving the expenditure of $436,760 and a
contingency of $43,676 to modernize the aging system.
January’s rainfall has been unimpressive to date, and Jan Null,
veteran meteorologist with Golden Gate Weather Services, agrees
that the last week of the month looks relatively dry. Seasonal
precipitation totals for Northern and Central California
continue to fall behind normal.
Americans are flushing toilets 10 times, showers aren’t
cleaning people like they used to and dishwashers must run five
times to be effective. That’s President Trump’s latest twist on
environmental messaging as he makes his pitch for a second
term. And it’s one that political strategists said is
reflective of so many aspects of Trump’s political career.
A joint workshop hosted by the Department of Water Resources
and the State Water Board provides details on how incoming
plans will be evaluated and what State Water Board intervention
might look like.
We are on the brink of a historic accomplishment in California
water to resolve longstanding conflicts through comprehensive
voluntary agreements that substitute collaboration and creative
solutions for perpetual litigation. For anyone to abandon this
transformative effort in favor of litigation would be a tragic
mistake…
Farmers, large and small, are beginning to grapple with what
the Sustainable Groundwater Management Act means for them. One
by one, local sustainability plans are starting to go public.
Many farmers expect to see cutbacks on pumping once the program
is fully implemented in 2040.
Although water purified at the Silicon Valley Advanced
Purification Center is not currently part of Santa Clara
County’s supply of drinking water, the goal is to make that a
reality within the next decade or so.
The Santa Fe Irrigation District approved three percent water
rate increases for the next three years at a Jan. 16 hearing.
… The rate increases aim to help meet the district’s
objectives to ensure equity across customer classes, encourage
conservation and maintain financial stability as it faces
challenges such as the rising costs of imported water.
Utah first proposed building a 140-mile pipeline from Lake
Powell on the Utah-Arizona border more than a decade ago. The
plan, however, was waylaid by environmental and other reviews
during the Obama administration. … Reclamation signaled to
the state that it wants to move swiftly on the plan, in
recognition of how it was stalled at FERC…
In another valley, the disagreement might have blown over
without fanfare. But in Napa, which has been wrestling with
tensions between viticulture and environmental preservation,
the fight over Igor Sill’s vineyard took on a larger
significance.
President Trump yesterday touted his repeal of key Clean Water
Act regulations as more than three dozen current and former
government officials called for an investigation into the
scientific basis of his forthcoming replacement rule.
Gov. Doug Ducey is touting Arizona’s record on water while also
acknowledging the state has “more to do” in some areas. Ducey
talked about water policies this week in an interview for The
Arizona Republic’s podcast The Gaggle.
Mediterranean climates include California, and dry-farming of
cannabis is catching on in the Emerald Triangle as a part of
the general trend toward sun-grown and organic product.
Now Trump’s team is set to impose new environmentally damaging
Bay-Delta water diversion and pumping rules. … These new
rules would wipe out salmon and other wildlife by allowing
wholesale siphoning of water from Northern California rivers to
a few agriculture operators in the western San Joaquin
Valley.
Stamping out incorrect social-media information is like trying
to halt those computer viruses that multiply bad files every
time you close one. You can sometimes convince someone that the
story isn’t quite right – only to see it pop up on myriad other
feeds. … The specific story involved water rationing.
In a groundbreaking vote, California has allocated nearly $45
million toward boosting highly efficient electric heat pump
technology that can help avoid burning fossil fuels to heat our
water, as well as store California’s abundant pollution-free
solar energy to give us piping-hot showers when the sun isn’t
shining.
State water officials are blaming almond and pistachio orchards
for sinking the California Aqueduct before all the evidence is
in, according to one western Kern County water district
manager.
As Gov. Gavin Newsom and his administration attempt to
establish a comprehensive and cohesive water policy for the
state, officials are seeking public input on the draft water
resilience portfolio released earlier this month. The document
was issued in response to Newsom’s April 2019 executive order
directing his administration to inventory and assess a wide
range of water-related challenges and solutions.
Inside the dome on top of the Penitencia Water Treatment plant
in San Jose is the first permanent x-band weather radar system
in the Bay Area. “The radar system that you see up there is
collecting crucial data as we speak,” said Norma Camacho, CEO
of Valley Water.“ Camacho joined the San Francisco P.U.C.,
Sonoma Water and other partners in unveiling the new system,
which will improve weather forecasting across the region.
The Hyperion Water Reclamation Plant, located just south of
LAX, purifies water and injects it into the ground to act as a
barrier between seawater and fresh groundwater. … But the
idea is to one day recycle wastewater into drinking water and
put it right back into the system. The industry is moving
cautiously, though, given what you might call a considerable
“ick” factor for the public.
In order to provide ongoing funding for Sebastopol’s water and
sewer system, the Sebastopol City Council unanimously approved
an increase to water and sewer rates at its Jan. 7 meeting. …
The average ratepayer’s bill is expected to increase by $3 or
$4 per month, according to Mayor Patrick Slayter.
Even though water districts and cities throughout the San
Bernardino Valley rely on local rainfall and mountain runoff
for about 70 percent of their water supply, local supplies are
not enough. The region relies on Sierra snowmelt from Northern
California to meet the remaining 30 percent.
While Newsom has been forced to address climate change on many
fronts during the past year – think wildfires, blackouts and
automobile standards – the state’s myriad water challenges must
remain a priority. Our state’s water system is decades old and
needs to be re-envisioned for a new era.
SDSU, with the help of its landscape architect Schmidt Design
Group, hopes to engineer ties to the oft-overlooked San Diego
River, which runs behind the Mission Valley property currently
home to SDCCU Stadium. Although park-goers won’t be able to
access the river — a landscaped buffer will be used to keep
people away from the natural habitat — they should get a
river-like feel from the park.
In December, the boards of the Fallbrook Public Utility
District and the Rainbow Municipal Water District voted to
begin detachment from the San Diego County Water Authority in
order to join Riverside’s Eastern Municipal Water District.
Will those left behind pay more as others tap new supplies?
Questions are flying in Valley Center, where farms are the main
customers, even as avocado turf keeps shrinking.
If you manage a data center, you need smart water management
strategy. Fortunately, practical solutions to make that happen
are available today. Smart water management is a growing
necessity because of two colliding challenges: the need for
more data centers around the world and increasing global water
scarcity.
When was the last time that you heard a water district in
California complaining that in the future, they will have too
much water supply? Remarkably, that’s the future that the
Metropolitan Water District of Southern California (MWD)
outlined at their October 2019 Board of Directors’ retreat.
Because zone changes have the potential to impact many well
users, Valley Water conducted extensive stakeholder engagement
on the preliminary study recommendations. … The board of
directors agreed and directed our team to prepare the survey
description to modify the two existing zones, and create two
new zones in South County. The board will consider these
changes in a public hearing later this year.
Plenty of work is on the docket for 2020 and beyond to manage
and preserve Arizona’s water supply, even if that work might
not write history the way last year’s signing of the Drought
Contingency Plan did. … The state’s water managers are known
for prioritizing predictability and making careful, gradual
changes, not erratic or sudden ones. Here are five key
issues to watch this year in Arizona water.
Severe droughts have happened simultaneously in the regions
that supply water to Southern California almost six times per
century on average since 1500, according to new research. The
study is the first to document the duration and frequency of
simultaneous droughts in Southern California’s main water
sources—the Sacramento River basin, the Upper Colorado River
Basin, and local Southern California basins.
The Henry J. Mills Water Treatment Plant will be out of service
for nine days and the Western Municipal Water District will not
be able to import water, forcing the agency to rely on its
reserves, officials said. The work began Friday, Jan. 10, and
Metropolitan Water District of Southern California crews will
be fixing and modifying the facility until Jan. 19, according
to the agency.
Right now, the April-July runoff is supposed to be 82% of
average. That compares to 145 % of average in 2019, the
second-best runoff season in the past 20 years, says the
federal Colorado Basin River Forecast Center. Despite last
year’s excellent river flows, most experts also say the
Colorado still faces long-term supply issues…
San Francisco city officials and employees will no longer be
sipping bottled water, but instead tap water provided by the
San Francisco Public Utilities Commission under a new pilot
program announced Thursday. The program aims to install new
reusable five-gallon containers at nine departments with
offices within City Hall, filled with tap water from the city’s
water system.
Yes, aggregate mining on the San Joaquin has been going on for
more than a century. But with production tapering off and newer
operations opening on the nearby Kings River, it was generally
assumed the poor San Joaquin would finally be given a break…
Unfortunately, a proposal by Cemex threatens to dash those
hopes while ensuring another century of heavy industry on
California’s second-longest river…
Who can deny the value of potable water to every living thing
in this city, this county, this state? Four million residential
and industrial customers in 43 cities in the Los Angeles, San
Gabriel and San Fernando Basins are dependent on multiple water
sources – groundwater pumped from below them, by aqueduct from
the Colorado River, the Sierra Nevada snowpack, Mono Lake, the
Owens Valley and recycled from wastewater treatment plants.
Because the amount of groundwater pumped out far exceeds what
is naturally replenished by rainfall, Valley Water’s
groundwater management activities are critical to maintaining
healthy groundwater basins.
Every year since 2014, I have petitioned the State Water
Resources Control Board to end the widespread practice of
irrigation, especially of cattle pastures, outside the legal
irrigation season. So far, however, State Water Board staff
have not taken effective action to end the illegal water use
and the resulting degradation of Scott River stream
ecosystems…
When most think of the possible impacts of sea level rise, they
think of coastal flooding and the growing risks to shore-based
infrastructure — but there’s another sea level rise-related
threat that is much less talked about. As sea level rises, so
too will groundwater levels in coastal aquifers, and some
recent studies have concluded that in some coastal areas, as
much or more land could flood as a result of rising groundwater
tables than will flood directly from rising tides.
Along with long-term drought and climate change, the
overcommitment of the Colorado River is a big reason why Lake
Mead has dropped to historic levels in recent years. Fixing it
could be a big problem for Arizona.
As groundwater sustainability agencies prepare their plans to
meet the requirements of the Sustainable Groundwater Management
Act (SGMA), they will likely utilize a variety of tools to
achieve sustainability. … At ACWA’s fall conference, a panel
discussed the legal framework, different types of groundwater
rights, lessons learned from existing groundwater production
allocation programs, and potential pitfalls …
The Riverside County Sheriff’s Department says deputies were
dispatched Monday when a person in the city of Perris reported
they had not seen their neighbor for several days and a steady
flow of water coming out of the residence was flooding yards.
Farm organizations welcomed a new water planning document from
state agencies while they analyzed the document’s proposed
strategies. Titled the California Water Resilience Portfolio
and released last week, Gov. Gavin Newsom’s administration
described the document as an effort to guide water management
in a way that works for people, the environment and the
economy.
Consistent with the science developed over the last three
decades, the Newsom administration is pursuing comprehensive,
watershed-wide solutions that address the numerous factors that
limit the abundance of native fish in the Delta. These types of
solutions are the ones that are most likely to achieve the
state’s co-equal goals of the 2009 Delta Reform Act…
California will impose new limits on water usage in the
post-drought era in the coming years — but a claim that
residents will be fined $1,000 starting this year if they
shower and do laundry the same day isn’t true. It wasn’t true
when the state’s new conservation laws were enacted in 2018,
and it isn’t true now — despite a recent report on a Los
Angeles television station …
The Fresno County Board of Supervisors adopted a plan on
Tuesday meant to maintain groundwater and keep users from
pumping too much from underground basins. … Officials said
the plan also lays out efforts to try to recharge groundwater —
in other words, replace water sucked out from underground.
These changes will be substantial, multi-faceted, and often
rapid. Some changes will be irreversible. Many changes are
inevitable. Some will say today’s Delta is doomed. It will be
important for California to develop a scientific program that
can help guide difficult policy and management discussions and
decision-making through these challenges.
In the early years of the 20th century, leaders across the West
had big dreams for growth, all of which were tied to taking
water from the Colorado River and moving it across mountains
and deserts. In dividing up the river, they assigned more water
to users than the system actually produces.
Evaporation ponds, which are commonly used in many industries
to manage wastewater, can span acres, occupying a large
footprint and often posing risks to birds and other wildlife.
… Now researchers at the Department of Energy’s Lawrence
Berkeley National Laboratory have demonstrated a way to double
the rate of evaporation by using solar energy and taking
advantage of water’s inherent properties.
