As the single largest water-consuming industry, agriculture has
become a focal point for efforts to promote water conservation.
The drive for water use efficiency has become institutionalized
in agriculture through numerous federal, state and local
programs. Since the 1980s, some water districts serving
agricultural areas have developed extensive water conservation
programs to help their customers (From Aquapedia).
All residents and organizations within the Indian Wells Valley
will have to implement register their wells come Oct. 1
following the approval of an ordinance by the Indian Wells
Valley Groundwater Authority board of directors.
On the modern farm, soil sensors, well monitors and paperwork
abound. The trick is trying to keep all that data organized. To
that end, a Monterey County winegrape grower, Scheid Family
Wines of Greenfield, came up with its own system, first called
VitWatch, to digitize information previously recorded on paper.
Recent validation by state regulators of the effective and
sustainable management of Coachella Valley’s groundwater basins
speaks volumes about the importance of collaboration by local

The Lake Powell Pipeline (LPP) proposal arose from a belief
that Utah has an unused share of the Colorado River and a fear
of water shortages stifling Washington County’s rapid
population growth. Although many leaders across the state say
southern Utah needs the LPP, this statement is not based on
Arizona, Nevada and Mexico will be required to take less water
from the Colorado River for the first time next year under a
set of agreements that aim to keep enough water in Lake Mead to
reduce the risk of a crash.
During the drought of 2012-16 landowners pumped more and more
groundwater to compensate for the lack of rain. Thousands of
wells ran dry. As a result, California passed a law requiring
water users to organise themselves into local Groundwater
California was the last Western state to pass legislation
regulating groundwater: the Sustainable Groundwater Management
Act of 2014 arrived after more than a century of development,
intensive agriculture, bouts of drought and the looming threat
that our aquifers will dry up. But the details of who would get
to pump what – and the financial cost of achieving groundwater
sustainability – are only now becoming clear.
Some areas of the country are predicted to see increased
flooding from hurricanes and other storms, while climate models
show the West, particularly California, will be getting dryer.
This will especially affect the water supply in California and
here locally in the Santa Clarita Valley, where we have long
depended on water from the melting Sierra snowpack to get us
through our hot, dry summers.
The U.S. Bureau of Reclamation on Thursday will release its
projections for next year’s supply from Lake Mead, a key
reservoir that feeds Colorado River water to Nevada, Arizona,
California and Mexico. After a wet winter, the agency is not
expected to require any states to take cuts to their share of
water. But that doesn’t mean conditions are improving long
With the Indian Wells Valley Groundwater Authority Board of
Directors set to pass an ordinance requiring mandatory
groundwater well registration on Aug. 15, a looming question
remains: how to notify residents in the valley.
California could be the canary in the coal mine. Over the next
decade, 40 U.S. states are expected to experience water
shortages, according to the U.S. Government Accountability
Office. The situation is serious, but California’s
entrepreneurs, who are seeking to boost supply and tame demand,
offer a glimmer of hope.
In a 2018 Public Policy Institute of California (PPIC) survey,
80 percent of respondents said climate change is a serious
threat to California’s future. And 72 percent cited water as a
concern, with drought and water supply named most frequently as
our biggest environmental issue. If you see yourself in these
statistics, you should be cheering the efforts of California
The recently adopted Drought Contingency Plan (DCP) was an
important step toward addressing the Colorado Basin’s chronic
water shortages, but more work is needed to prepare for a
hotter, drier future. We talked to Doug Kenney, director of the
Western Water Policy Program at the University of Colorado and
a member of the PPIC Water Policy Center research network,
about managing the basin for long-term water sustainability.

of Denver, the partnership aims to make the river function
better for people and the environment.
What would happen if we ran out of water? For an increasing
number of people, that question is moving from a hypothetical
to a reality. New data from the World Resource Institute show
that a quarter of the world’s population is at high risk of
running out of water.
Many farmers probably haven’t read the new report from the
United Nations warning of threats to the global food supply
from climate change and land misuse. But we don’t need to read
the science — we’re living it. Here in the San Joaquin Valley,
one of the world’s most productive agricultural regions,
there’s not much debate anymore that the climate is changing.

Ample water resources in northern areas of California are
balanced by huge demands from Central Valley agriculture and
the large populations in hotter, drier southern areas such as
Los Angeles and San Diego. California uses the most water of
any state, according to the U.S. Geological Survey, up to 9
percent of all withdrawals from the national supply.

Holly Foster, whose family runs cattle in Butte and Plumas
counties, said her ranch lost power during a shutoff in June
that affected Butte, Napa, Solano, Yolo and Yuba counties. Her
cattle in Butte County are particularly vulnerable because she
relies on electricity to pump water from wells.
An important but not widely-publicized local planning process

Whether you are a water utility manager, elected official, or
homeowner, future water availability is a concern. There are
several factors fostering that concern and one of them is
climate change. … But as the empirical evidence mounts and a
once doubtful citizenry become more informed, it is instructive
to review what a changing climate fundamentally means to
California’s water resources; arguably our most important.
A Butte County project will expand its partnership with Chico

A San Luis Obispo County policy regulating pumping from the
Paso Robles Groundwater Basin has hamstrung how Robert
Galbraith can farm his land. For decades, the family grew corn
silage, Sudan grass, alfalfa, and grains on their few hundred

though he can see many a green vineyard down the road.
While it may not be obvious to some, sustainable groundwater
management is inherently connected to the long-term survival of
the Delta. Not only does the state’s most significant
groundwater use occur in regions that also rely upon water from
the Delta watershed, reduced reliance on the Delta and improved
regional self-reliance are central to many of the goals
outlined in the Delta Stewardship Council’s Delta Plan.
The Groundwater Sustainability Agency board will submit a
sustainability plan to the Department of Water Resources in
2021 and begin to implement that plan in 2022-2024. The board
last week heard a presentation about funding options to pay for

The report estimates there are a cluster of major California
crops that are particularly vulnerable to extreme temperature
changes: wine grapes, lettuce, almonds, strawberries, table
grapes, hay, oranges, cotton, tomatoes, walnuts, avocados, and
pistachios. Specifically, avocado production in California
could fall 40 percent by 2050 due to climate change factors.
More than 90% of U.S. wine comes from California, despite
growth in other states’ production, and it’s putting a strain
on the environment. Throughout the region, wine producers say
they’re striving to save water and use less pesticides, among
other measures aimed at sustainable growing, as they face the
challenges brought on by the advance of climate change.
The newly formed water market would create a place where
farmers in the Rosedale district can buy and sell water based
on their needs. So if one farmer has too much for his crops in
a certain year, he’d be able to sell it on the market to
another who might not have enough.
High-tech firms like Ceres, Prospera, Farmers Edge, and the
Climate Corporation are using artificial intelligence to help
famers decide when to plant, water, spray, and harvest their
crops. As climate change worsens rainstorms in the Midwest and
drought in California, the technology could also help growers
navigate more severe and volatile weather.
Thoughtfully implementing state law that requires local water
users to bring groundwater use to sustainable levels within the
next two decades will … result in withdrawal of large amounts
of land from agricultural production and the loss of economic
benefits. But we can repurpose those lands to support large
scale storage and solar, as well as other renewable energy
technologies that can help decarbonize our electric grid and

The Friant Water Authority is confident a parallel canal is the
best solution. This new one will be built in a way that
prepares for subsidence. A new canal would also benefit from
the Ground Water Management Act of 2014, which will regulate
how much and when water is pumped out of the ground, preventing
what some believe is the main cause of subsidence.
The state drought plans move gingerly toward encouraging
transfers of water by using clever euphemisms that avoid any
mention of water marketing. … These euphemisms are tools that
usher in a new frontier in western water law that will increase
resilience in the face of droughts, floods and forest fires
fueled by climate change.
How can the short memory of the public maintain the long-term
commitments of water projects and conservation behaviors? On
one hand, California’s recent extended drought demonstrated
that the public water users could reduce their water use, but
can it be maintained permanently?
The Indian Wells Valley Groundwater Authority board of
directors took the first step Thursday to require all
groundwater wells in the valley to be registered by Oct. 1. …
That first step also included a pumping fee to pay for the

sourcing ingredients from farms that have restored
salmon-inhabited streams and limited their use of water and
Many Delta problems are worsening. Climate change is raising
sea levels and temperatures, making floods and droughts more
extreme and will likely further alter the mix of species. State

Groundwater overdraft is a major problem globally and has been
a persistent and growing problem in California for decades.
This overdraft is predominantly driven by the economic value of
water for agricultural production and cities.
Agricultural scientists across the globe including at Stanford

this summer as the city’s mandatory water conservation program
continues to push through its first of eight phases.
Proponents have said SB 1 will keep Trump from delivering more
water to farms, thereby harming endangered fish. That sentiment
is exactly what makes SB 1 so dangerous. It relies on the
worn-out trope that California’s water issues boil down to
“farms versus fish.”
If we can make things just a bit easier and provide reliable

it’s intended for, has a great impact in our Central Valley.
An irrigation district may adopt and enforce reasonable rules
related to water service, and may terminate water delivery for
failure to comply with such rules, a California appellate court
ruled. Although this case involved an irrigation district, the
decision may also strengthen other water providers’ authority
to adopt and enforce rules relating to water service.
Agricultural water suppliers must develop annual water budgets
and drought plans that meet requirements of recently enacted

The plan is historic: It acknowledges that southwestern states
need to make deep water use reductions – including a large
share from agriculture, which uses over 70% of the supply – to
prevent Colorado River reservoirs from declining to critically
low levels. But it also has serious shortcomings. It runs for
less than a decade. And its name suggests a response to a
The Rosedale-Rio Bravo Water Storage District’s pilot program,

Pistachio trees require somewhere between one-third and
one-half as much water as almond trees. Unlike almond trees,
pistachio trees don’t die during extended droughts. Their
metabolism merely slows and when water returns, they start
producing nuts again. … Pistachios can also handle, as
Duarte’s team discovered, levels of salt that have already
killed many an almond tree.
We need a broad portfolio of solutions that includes storage
above and below ground, conservation, and other options such as
traditional recycled and potable reuse to help ensure we can
better manage this vital resource when the next inevitable
drought comes along. … One part of that solution is the
proposed Sites Reservoir.
Santa Barbara County’s water supply outlook has improved
significantly with a winter of strong rains, and this is

Oscar Meinzer (1942) credits Leonardo da Vinci (1452-1519) with
having advocated the infiltration theory slightly before
Palissy’s time, basing his theories on observations made when
he was in charge of canals in the Milan area. … Such a
scenario might explain why California DWR staff and like-minded
academics and nonprofits have all jumped on the bandwagon of
managed aquifer recharge.
With a big collective sigh of relief, Californians rejoiced
that we have largely recovered from 2012-2016 drought. But this
is not a time for complacency… This should thus be a time to
develop new and better strategies for reducing impacts of
severe drought on both natural and developed systems.
An important blueprint for the success of farming in the

In the long-term puzzle of ensuring that the Colorado River —
the main artery of the American West — provides water to the
millions of people in the basin who depend on it, the
challenges are mounting. Does 2019’s water stand a chance of
making a meaningful impact? Water experts say the answer is:
Sadly, not likely.
SGMA inevitably means less water for irrigating farms. … On
one path, the valley could become a patchwork of dusty barren
fields, serving a huge blow to the agriculture sector and rural
communities and further impairing already poor air quality. …
On another path, the valley could transform into a pioneering
agricultural region that not only puts food on our nation’s
plates but also supports thriving wildlife habitat, outdoor
recreation, soil health, groundwater recharge and flood
The update reported an excellent May in terms of Colorado River

Coordinating Group unanimously voted to inform the governor
that Arizona’s long-running drought declaration should
continue. This means Arizona has been in a state of drought for
more than 20 years, surpassing the worst drought in more than
110 years of record keeping. Now that our drought has been
extended yet again, it leaves many to wonder what it will take
to get us out of this drought.
Once again, a big thirsty metropolis is looking at buying
Central Valley farmland with an eye toward boosting its water
supplies. And once again, neighboring farmers are nervous about
it. … And any proposal involving the movement of groundwater
from a rural area creates controversy, especially as farmers
begin to implement the Sustainable Groundwater Management
Even though the Russian River watershed has received roughly
130 percent of the average rainfall this season, it is time to
discuss the impacts of overwatered landscapes as the dry
weather returns and irrigation controllers turn on.
As the Colorado River’s flow declines, water supplies in seven
states are imperiled by potential shortages. That includes
Arizona, which passed legislation outlining steps it would take
if water from the river continues to decrease. But what does a
water shortage mean for Phoenix?
It’s hard to respond effectively to a crisis when you don’t
have clearly defined priorities. This is true for sudden-onset
crises, like floods and wildfires, and also for slow-onset
crises, like droughts.
The Kern County Water Agency supports the state’s “reset” to a
one-tunnel approach because it is more cost effective and still
prepares California’s water system for earthquakes and climate
change while protecting the Delta’s fish and communities.
University of Colorado Professor Emeritus Charles Wilkinson …
described the Western icon and one-armed Civil War veteran as a
complex character, a larger-than-life person and an early
visionary of wise water use in an arid West. Wilkinson spoke
recently with Western Water about Powell and his legacy, and
how Powell might view the Colorado River today.
It appears Solano County and Vallejo have avoided a potentially
costly state shift in the groundwater sustainability priority
for the Napa-Sonoma Lowlands. While the final decision by the
Department of Water Resources has not been made, the state
agency has for now backed off its proposal to increase the
priority status from very low to medium for the lowlands.
The Bureau of Reclamation updated its 2019 allocation for the
Central Valley Project South-of-Delta, increasing the westside
water allocation to 70 percent of the contract total. Said
Mid-Pacific Regional Director Ernest Conant: “The late storms
provided an added boost to the already above average
precipitation for 2019. Snowpack throughout the state is still
about 150% of average for this time of year.”
The history of Traver, preserved in many books and archives, is
a study in land development, agriculture and irrigation. It
started when a civil engineer named Peter Y. Baker conceived a
plan to convert thousands acres of rangeland in northern Tulare
and southern Fresno counties into fields of wheat by diverting
water by canal from the Kings River.
A firm hired by the Indian Wells Valley Groundwater Authority
is already in the initial phase to find sources of imported
water for the valley, according to a progress report delivered
at a Thursday board meeting. … Capitol Core Group, retained
in March, is looking at what water supply options are available
and how to secure funding to ultimately purchase and develop
infrastructure to deliver into the valley.
As the focus on infrastructure retakes center stage in
Washington, we hope lawmakers don’t overlook a prime
opportunity to invest in Western water and irrigation systems.
Here in the West, our dams, irrigation systems, canals and
other infrastructure — much of it more than a century old — are
past due for modernization.
Last fall, a team of researchers at the Public Policy Institute
of California (PPIC) studied the state’s response to the
extreme drought conditions, distilling their findings down to
four essential reforms that will better prepare the state to
adapt to the impacts of climate change. At the Association of
Water Agencies of Ventura County’s Annual Symposium held in
April of 2019, Ellen Hanak, Director of Public Policy Institute
of California’s Water Policy Center gave this recap of their
The session, “Navigating the Waters,” drew a crowd of about 150
farmers to the International Agri-Center in Tulare last week,
where attendees heard from water-agency leaders, state water
officials, farmers and others on a range of topics with the
goal of helping almond growers make informed water decisions.
On Tuesday, May 21, the Board of Directors of the Sonoma County
Water Agencyand the Sonoma County Board of Supervisors approved
a plan to offset a fee that is likely to be imposed on
groundwater users in the Santa Rosa Plain… Under the plan,
the County and Sonoma Water would contribute up to $240,000
annually for three years to the Santa Rosa Plain Groundwater
Washington Gov. Jay Inslee has declared a drought emergency
across nearly half the state. The drought declaration covers
the Olympic peninsula, the North Cascades, the eastern Cascades
and most of southwest Washington. It allows local governments
to tap into $2 million in state funding to respond to hardships
caused by the drought. … Snowpack is now at its fourth-lowest
level in the past 30 years.
I ran down a quick summary this morning of the relevant data,
comparing recent use with the cuts mandated under the DCP. It
shows that, at this first tier of shortage, permitted use is
less than the voluntary cuts water users have been making since
2015. In other words, all of the states are already
using less water than contemplated in this first tier of DCP
In 2016, California became the first state to pass legislation
regulating dairy methane, requiring the farms to cut their
manure emissions 40% by 2030. … Enter Neil Black. Black’s
company builds multimillion-dollar projects at the state’s
largest dairies to capture the gas.
To Eastern Sierra residents, in most years, annual run-off
means the streams and canals rise and pasture lands start to
green-up. For Los Angeles Department of Water and Power,
run-off is the city’s life’s blood… So, how do they figure it
out? Eric Tillemans, LADWP engineer, gave the Inyo County Board
of Supervisors a beginner’s course in Run-Off 101 at a recent
The Humboldt County Board of Supervisors voted unanimously to
investigate becoming a stakeholder in the Potter Valley
project, a massive water development in the Eel and Russian
river basins. … The idea is to protect the Russian River’s
water supply for Potter Valley residents while mitigating the
effects of the Scott Dam on Eel River fish populations.
Contaminated groundwater is an ongoing problem in some of the
state’s poorest rural communities, particularly in the San
Joaquin Valley. One big threat is nitrate, caused mainly by
many decades of crop fertilization with chemical fertilizers
and dairy manure. We talked to Anja Raudabaugh of Western
United Dairymen about what can be done to address these
The Colorado River just got a boost that’s likely to prevent
its depleted reservoirs from bottoming out, at least for the
next several years. Representatives of seven Western states and
the federal government signed a landmark deal on Monday laying
out potential cuts in water deliveries through 2026 to reduce
the risks of the river’s reservoirs hitting critically low
Mission Springs Water District alleged that Desert Water
Agency, which also provides water to more than 100,000 Palm
Springs and Cathedral City residents, made a board decision
that violated a previous settlement between the two agencies.
… Last month, the issue over groundwater management in Desert
Hot Springs picked up steam when a study group
formed by Mission Springs published a 16-page report that
lambasted Desert Water Agency’s actions…
There is a unique partnership happening in Arizona between
farmers, those involved in the malting process, and brewers
that is saving thousands of gallons of water from being taken
from the Verde River.
It takes more than one wet year to not only refill reservoirs
but also recharge aquifers and return moisture in parched soils
to normal levels. … All this upstream snowpack and rain is
predicted to boost Powell to 47% of capacity by the end of the
year, another three or four feet, but there’ll still be plenty
of the “bathtub ring” visible. It’s been 36 years since Powell
was full. It’s not likely it’ll ever fill again.
After months of tense, difficult negotiations, a plan to spread
the effects of anticipated cutbacks on the drought-stricken
Colorado River is nearing completion. On Monday,
representatives of the seven states that rely on the river will
gather for a formal signing ceremony at Hoover Dam, the real
and symbolic center of the Lower Basin Drought Contingency
Napa County’s latest watershed symposium came at a time when
tensions are high over how to protect trees and reservoirs in
the area’s mountains. Close to 200 people from various
backgrounds came to Copia on Thursday for an A-to-Z look at
what’s happening in the watersheds. Scientists, elected
officials, wine industry members and citizen activists all
The Colorado River — of which the Green is the biggest
tributary — is the main water source for 40 million people.
It’s already overallocated, and climate change is predicted to
shrink flows by up to 50 percent by the end of the century.
We’re finally coming to grips with those forecasts and
beginning to heed Powell’s century-and-a-half-old warnings. But
it’s taken drought and desperation to get us there, and we have
to do better.
Arizona relies on groundwater for about 40% of its water
supply, yet groundwater resources outside of the state’s
biggest urban areas are largely unprotected and unregulated…
HB 2467, a bill that passed in the Arizona House and currently
awaiting a final vote in the Senate, takes an important step
forward to address groundwater challenges in Mohave and La Paz
In the ceaseless conflict over how to use the state’s available
water — and maybe then some — a varied group of water users and
lawmakers sang a refrain older than Nevada: “Everyone is going
to court in the end.” … The ghosts of litigation — past,
present and future — loomed over the Thursday Senate Natural
Resources Committee hearing that stretched until 8 p.m. and
offered insight into why it’s so difficult to update Nevada
When you hear news about ice loss from Greenland or Antarctica,
an aquifer in California that is getting depleted, or a new

Insisting the state made a commitment, a central Arizona
lawmaker and farmers he represents are making a last-ditch
pitch for $20 million from taxpayers to drill new wells and
water delivery canals. Rep. David Cook, R-Globe, said Thursday
the farmers in Pinal County agreed to give up their right to
Colorado River water to help the state come up with a plan to
deal with the drought. In exchange they were given the right to
take additional water out of the ground.
The Western-San Bernardino and Orange County judgments, signed
April 17, 1969, helped establish five watermasters and settle
water rights throughout the watershed that supplies the water
agencies within San Bernardino, Riverside and Orange counties.
The agreements settled decades of lawsuits over water rights…
Oregon Water Resources Department is in the process of
validating a call on Upper Klamath Lake tributaries, including
the Wood River, filed by senior water right holders — the
Klamath Tribes — on April 18. … Water users that irrigate can
call the watermaster’s office if they believe someone with a
junior water right to theirs is irrigating with water that
should be coming to them.
When asked about his priorities, California’s recently
appointed Natural Resources Secretary quickly rattles off a
range of topics: climate change; strengthening water supply
resilience; and building water capacity for communities,
agriculture, and the environment, among them.
Researchers at the University of California, Davis, looked at
using a “free” resource — rain water stored in the soil — and
found that optimizing its use could go a long way to help meet
demand for five California perennial crops. Their findings
appear in the journal Environmental Research Letters.
Stakeholders throughout the Colorado River Basin just wrapped
up arduous negotiations on a drought plan. There’s little time
to rest, however. Stakeholders are expected to begin the even
more difficult task of hammering out sweeping new guidelines
for delivering water and sharing shortages that could
re-imagine how the overworked river is managed.
At the 28th California Water Policy conference held in April of
2019, a panel discussed how tribal lands and tribal
representatives, as independent nations, can be integrated into
SGMA implementation, what some of the obstacles to doing so
are, and how those hurdles might be transcended.
California Trout, Mendocino County Inland Water & Power
Commission, and Sonoma Water have officially put a foot forward
to explore a planning agreement for the project’s future. The
coalition is championing a “two-basin solution” that could
mitigate the effects of the Scott Dam on fish populations in
the Eel River while ensuring that the Russian River basin
doesn’t lose its water supply, which Potter Valley residents
have relied on for over 100 years.
Over the short life of the Sustainable Groundwater Management
Act, Owens Valley has gone from medium to high and now low
priority. That prioritization would have had an impact three
years ago. Medium and high priority basins are required to form
an agency and sustainability plan; low basins are not.
The big conflicts are deeply interconnected and appear to be
reaching their climactic phases. How they are resolved over the
next few years will write an entirely new chapter in
California’s water history, changing priorities and perhaps
shifting water from agriculture to urban users and
This river provides water for one-third of Latinos in the
United States. Latinos make up the bulk of agricultural workers
harvesting the produce this river waters. We boat, fish, swim
and recreate along its banks. We hold baptisms in its waters.
Therefore, it is critical to engage the growing Latino
population on water-smart solutions.
With the administration’s leadership, representatives of
farmers, cities and conservation groups are having productive
negotiations on a complex package of actions that would
increase river flows and improve fish habitats, collectively
called a “voluntary agreement.” A possible final agreement is
months away, but we are making progress.
Five years ago, Deb Fallows and I made the first of what became
many visits to the farming town of Winters, California. …
When we first visited five years ago, the main question for the
area’s nut-tree farmers, and for California’s agricultural
economy as a whole, was whether the state’s drought-ravaged
water supplies could support such commercially valuable but
In reality, the WaterFix could not increase water exports while
protecting the Delta ecosystem. That’s because California’s
snow and rainfall are highly variable, making it unlikely that
existing supplies can meet increasing water demands reliably
into the future. Plus, the science demonstrates that San
Francisco Bay’s fish and wildlife need more water, not less, to
flow from the Central Valley to the Bay.
The DCP … provides assurance against curtailments for water
stored behind Hoover Dam. This is especially important for the
Southern California water agencies, whose ability to store
water in Lake Mead is crucial for managing seasonal demands.
Some significant challenges must still be addressed, however.
Because of the wet weather this winter, the district is
proposing to lower its Stage Two Drought Condition to a Stage
One Drought Condition, which would lift many mandatory drought
The lawsuit against the Fresno-based Westlands Water District
was filed in Shasta County Superior Court on Monday. State
officials have for years maintained that raising the height of
the dam would violate the Wild and Scenic Rivers Act because a
higher dam would further inundate the McCloud River, in
violation of state law.
Estimates vary, and can change as the water year progresses,
but the Kern River basin, the rivers and streams that collect
the water that flows into Isabella Lake and downstream toward
Bakersfield, is estimated to be at 172 percent of normal,
possibly more. And all that ice and snow is starting to melt,
big time. Are local water managers ready?
The West is still in the midst of a long-term water shortage in
Lake Powell and Lake Mead, primary reservoirs that serve 40
million people. For that reason, the Upper Basin states —
Colorado, Utah, Wyoming and New Mexico — have to also come up
with their own drought contingency plans. That means Colorado
might be heading into choppy waters as one of the requirements
of a drought contingency plan — demand management — could pit
communities and regions against each other …
In Ukiah Thursday, at least two dozen people who depend on the
Potter Valley Project for their farming operations gathered at
the Redwood Empire Fairgrounds to hear an update on the
facility’s future. “New information to come shortly, and a lot
of work still to do,” said Janet Pauli, chairwoman of the
Mendocino County Inland Water and Power Commission, a Joint
Powers Authority that is exploring the possibility of acquiring
the facility that Pacific Gas and Electric owns, but has
For rural communities in the central coast region of
California, the name “Harvard” does not connote excellence. For
these communities, where water is scarce and becoming scarcer,
it evokes greed and exploitation. As California takes its first
steps to regulate groundwater in the midst of a worsening water
crisis, Harvard’s endowment fund is investing millions into
vineyards that pump inordinate amounts of water from
California’s critically overdrafted groundwater basins.
A Q&A with Valerie Olson, assistant professor, and Emily
Brooks, post-doctoral researcher — both environmental
anthropologists at UC Irvine. They have a new project aimed at
getting a better understanding of how communities, particularly
the underserved, think about and use their water, and how the
agencies that provide water can better serve them.
Set to expire in 2026, the current guidelines for water
deliveries and shortage sharing, launched in 2007 amid a
multiyear drought, were designed to prevent disputes that could
provoke conflict. … But as the time for crafting a new set of
rules draws near, some river veterans suggest the result will
be nothing less than a dramatic re-imagining of how the
overworked Colorado River is managed…
Implementation of the Sustainable Groundwater Management Act
(SGMA) was always going to be tricky. Part of the necessary
growing pains of SGMA is determining how the revolutionary
statute interacts with traditional tenets of water law. As with
any other sweeping legislative change, SGMA does not provide
direct answers for every practical question which arises as the
law is put into place.
State Assembly Member Eduardo Garcia says he wants to
“facilitate” negotiations more than a decade early on a 99-year
compromise between the Imperial Irrigation District and a
Coachella water agency that spells out how IID provides
electric power to Coachella Valley. IID President Erik Ortega,
however, said he is not “comfortable” with Garcia’s sudden
The Imperial Irrigation District board of directors voted
Tuesday to allow access across its lands for critically needed
state wetlands projects at the Salton Sea, designed to tamp
down dangerous dust storms and give threatened wildlife a
boost. In exchange, California will shoulder the maintenance
and operations of the projects, and the state’s taxpayers will
cover the costs of any lawsuits or regulatory penalties…
Before California’s Central Valley became known as an
agricultural powerhouse, it contained one of the largest
expanses of streamside forest and wetland habitat in North
America. … Much of that landscape has been transformed into
farmland and urban areas, but at the Cosumnes River Preserve, a
unique partnership of nonprofits and state, federal and local
governments has conserved over 50,000 acres that provide
resources for a variety of wildlife.
By monitoring tiny changes to the Earth’s gravitational field,

In the past several years, Los Angeles-based Renewable
Resources Group has helped sell 33,000 acres of land to
California’s most powerful water agency, the Metropolitan Water
District of Southern California. Documents obtained by Voice of

Renewable may be working on another deal that could rearrange
the distribution of water in California forever.
In California, there are around 300 species at risk and 346
species in California, Nevada and Southern Oregon combined. A
handful of plants and animals have already disappeared from the
state, such as the Santa Barbara song sparrow and the the
California subspecies of the Grizzly Bear. … About a dozen
species are currently at risk of extinction, according to Dan
Applebee, an environmental scientist with the California
Department of Fish and Wildlife.
According to the Bureau of Reclamation, the snowpack in the
Upper Basin is nearly 140% above average as of April 15 and it
forecasts that seasonal inflow to Lake Powell will be at 128%
of average. … “These developments may lessen the chance of
shortage in 2020,” Terry Fulp, BOR’s Lower Colorado regional
director, said in a prepared statement.
Vertical farming also brings potential for solving our current
and projected water issues in California. By using hydroponic
system technology, water is constantly recycled and uses 98%
less water per item than traditional farming. Adopting this
technology would be greatly beneficial for our future,
considering that California’s agricultural sector uses 40% of
Once one of most extensive wetland areas in North America, the
edges of the San Francisco Bay have become covered with farms,
