As adjacent Western states, California and Nevada share similar
issues related to drought and limited water resources. Both
states are participants in the 1922 Colorado River Compact and
the 2003 and 2007 Quantification Settlement Agreements to
allocate Colorado River deliveries. Also, about two-thirds of
Lake Tahoe lies in California and one-third in Nevada, and the
two states have formed a compact to work together on
environmental goals for the lake.
Located at the Knudtsen Resource Center at the University of
Nevada, Reno, the lab will provide agriculture-focused
analytical services to support faculty- and student-led
research at the University. The lab is also offering analytical
services for a fee to the general public, including property
owners and homeowners, who may need to have soil or water
samples analyzed.
A team of scientists at Utah State University has developed a
new tool to forecast drought and water flow in the Colorado
River several years in advance. Although the river’s headwaters
are in landlocked Wyoming and Colorado, water levels are linked
to sea surface temperatures in parts of the Pacific and
Atlantic oceans and the water’s long-term ocean memory.
Despite that reduction in flow, total storage behind Glen
Canyon and Hoover dams has dropped only 2.6 million acre feet.
That is far less than you’d expect from 12 years of 1.2 maf per
year flow reductions alone. That kind of a flow reduction
should have been enough to nearly empty the reservoirs. Why
hasn’t that happened? Because we also have been using less
water.
On September 17, 2020, the Nevada Supreme Court issued a
decision on whether Nevada’s public trust doctrine permits
reallocation of water rights previously settled under Nevada’s
prior appropriation doctrine. The majority found that the
public trust doctrine does not permit such reallocation.
In the area that the Moapa Valley Water District serves, water
users are facing an uncomfortable future: People are going to
have to use less water than they were once promised. Over the
last century, state regulators handed out more groundwater
rights than there was water available. Today state officials
say that only a fraction of those rights can be used, which
could mean cuts.
U.S. and tribal officials are celebrating completion of a $34
million fish bypass system at a Nevada dam that will allow a
threatened trout species to return to some of its native
spawning grounds for the first time in more than a century.
Construction of the side channel with fish-friendly screens is
a major step toward someday enabling Lahontan cutthroat trout
to make the same 100-mile journey — from a desert lake
northeast of Reno to Lake Tahoe atop the Sierra — that they did
before the dam was built in 1905.
According to river flow data, there is currently almost no
water flowing into Walker Lake, a common condition. Today,
where the riverbed meets the lake is an ooze of mud. The lake
is all but biologically dead. But a decades-old public trust
lawsuit made a move forward in its glacial process through
federal courts last week, and advocates are hopeful Walker
Lake, a cornerstone of the regional economy and ecology, can
one day be revived.
On Wednesday, the Bureau of Reclamation joined its partners,
U.S. Fish and Wildlife Service and Farmers Conservation
Alliance, to celebrate the completion of the Derby Dam Fish
Screen Project. The infrastructure modernization project at
Derby Dam will provide Lahontan Cutthroat Trout access to
natural spawning grounds for the first time since 1905.
The recent downgrade in the forecast for the flow of water in
the Colorado River should be a death punch to the proposal to
build a new pipeline out of Lake Powell. The pipeline was
already a major threat to Las Vegas and much of the rest of the
Southwest; now the threat risk is heading off the charts.
The monsoon season — that period from mid-June through
September that each year brings rains to the Mojave Desert and
other areas of the Southwest from the tropical coast of Mexico
— has been a dud this year. Las Vegas is in the middle of a
record-breaking stretch without rain, and residents should be
prepared for it to stay that way, scientists say.
Regional water conservation groups and a Clark County
commissioner welcomed a request by Utah officials Thursday to
extend the federal environmental review of a controversial plan
to divert billions of gallons of water from the Colorado River
to southwest Utah.
Lawyers representing Mineral County and the Walker Lake Working
Group announced this week they intend to take a water rights
case with broad implications back to federal appeals court to
ask whether Nevada can adjust already allocated water rights to
sustain rivers and lakes long-term.
We analysed data reported by the Bureau of Reclamation and the
U. S. Geological Survey that describe the primary inflows to
Lake Powell and the Colorado River between Glen Canyon Dam and
Lake Mead, as well as the losses from both reservoir and the
releases from Hoover Dam. … The significance of the
uncertainties we identify can be measured by reminding the
reader that the annual consumptive uses by the state of Nevada
cannot exceed 300,000 acre feet/year…
In Utah, there is a significant effort underway to build a
water delivery pipeline from Lake Powell to transport part of
Utah’s Colorado River entitlement to Utah’s St. George area. As
the federal environmental review for the proposed Lake Powell
Pipeline in Utah continues, Utah’s six fellow Colorado River
Basin states weighed in as a group, cautioning that unresolved
issues remain.
Last week, the Nevada Supreme Court ruled that the state’s
fundamental obligation to protect natural resources for future
generations did not allow it to reallocate water rights issued
under state law. The decision appeared to rule against
litigants pushing to restore Walker Lake, where the use of
upstream water rights has decreased the amount of water that
reaches the lake.
Over the years, these groups united against a single cause: the
Southern Nevada Water Authority’s “Groundwater Development
Project,” a proposal to pump 58 billion gallons of water a year
300 miles to Las Vegas from the remote rural valleys of Nevada
and Utah. … In May, their three decades of resistance to the
pipeline ended in victory: The project was terminated.
The Nevada Supreme Court ruled Thursday that the state cannot
reshuffle existing water rights to prevent environmental
damage, despite recognizing a legal principle that requires the
government to preserve natural resources for future
generations… The Nevada court, in a 4-2 decision, separated
itself from the California Supreme Court, which reached the
opposite conclusion in a landmark 1980s case.
The housing developer and the powerful water utility, locked
into past contracts, are caught in a fight, playing out in
hydrologic reports and hearing rooms, over what might seem a
simple question: How much water is there? That answer is
complicated by how much is at stake — a Colorado River
tributary, the survival of an endangered Nevada fish and the
future of development in a sweeping area outside Las Vegas.
Dizzying in its scope, detail and complexity, the scientific
information on the Basin’s climate and hydrology has been
largely scattered in hundreds of studies and reports. Some
studies may conflict with others, or at least appear to. That’s
problematic for a river that’s a lifeline for 40 million people
and more than 4 million acres of irrigated farmland.
Lake Powell isn’t in Southern Nevada. Rather, it’s about four
hours away by car in southern Utah. But some environmentalists
say the water consumption of St. George, Utah, and neighboring
communities could have a direct and deleterious impact on the
Las Vegas water supply.
The cuts are a plan to keep Lake Mead, a reservoir at the
Arizona-Nevada boundary, functional. Water levels have
precipitously dropped as a result of historic overallocation
and a drought that started in 2000. … ASU Now checked in with
Sarah Porter of the Kyl Center for Water Policy at the Morrison
Institute on how these new developments will impact the Copper
State and its residents.
The idea was to lower the flows while temperatures were still
warm enough to dry out the caddis larvae. That required buy-in
from local merchants and the Bureau of Reclamation, local
tribes and others. They were able to do it, and on Aug. 27, the
first of two flow reductions took place. When the river
dropped, people pitched in for a day of river cleanup.
Nevada officials raised numerous concerns Tuesday about a
proposed project to pipe large quantities of Colorado River
water roughly 140 miles from Lake Powell to southern Utah…
Six of the seven states that use the Colorado River also sent a
letter to federal water managers Tuesday asking them to refrain
from completing project permitting…
Nevada and California joined forces last week at the 24th
annual Lake Tahoe Summit to advance the states’ shared
priorities to protect and restore Lake Tahoe. … There is a
long history of collaboration between Nevada and California to
restore and protect the spectacular natural treasure of Lake
Tahoe and its surrounding environment. This spirit of
collaboration was a pillar of the 24th annual Lake Tahoe Summit
A developer is suing Nevada’s Division of Water Resources after
the state again denied plans to construct new homes at Coyote
Springs, the latest setback in a decades-long effort to build a
sprawling master-planned community about 50 miles north of Las
Vegas. Coyote Springs Investment alleges state officials made a
series of decisions that amount to an “unconstitutional taking”
of the water rights it owns and planned to use.
The new suit, filed Tuesday on behalf of three different tribal
groups and the Sierra Club, argues states and tribes have a
right to place conditions on federal projects that could
degrade waters within their borders or to reject them
altogether. “These changes that cut into the tribe’s ability to
protect its waters and fish harm us all,” Anthony Sampson,
chairman of the Pyramid Lake Paiute Tribe in Nevada, said in a
release.
A group of residents in Laughlin, Nev., which sits along the
Colorado River, are organizing a campaign to oppose a pipeline
that would divert billions of gallons of river water to
southwest Utah, reflecting intensifying struggles over water in
the U.S. West.
Above-average temperatures in spring resulted in a paltry 57%
runoff, nowhere near enough water to refill the reservoirs that
remain half-empty. Based on these conditions, the U.S. Bureau
of Reclamation recently determined that 2021 will be a “tier
zero” year under the Lower Colorado River Basin Drought
Contingency Plan, with reduced water deliveries for Arizona,
Nevada, and Mexico.
A friend last week pointed out something remarkable. Arizona,
California, and Nevada are forecast this year to use just 6.8
million acre feet of their 7.5 million acre foot allocation of
water from the main stem of the Colorado River. And that’s not
just a one-off.
Nevada and Utah share more than borders. We share the coveted
and much-fought-over Colorado River. But it seems as if only
one state — Nevada — is doing the difficult work to protect our
most valuable resource
The snow along the mountains of Nevada’s Great Basin trickle
down when the spring turns into summer. This produces a flurry
of wildlife and natural resources in our area ponds, rivers,
and lakes. … Along the majestic Truckee River, fishermen
would collect thousands of trout from the late 1800’s to the
1900’s. Eventually, this would cause the near extinction of our
state’s native species, the Lahontan cutthroat trout.
The latest forecast from the U.S. Bureau of Reclamation,
released last week, predicts that by the end of 2020, Lake
Mead, which furnishes Central Arizona Project water, will be at
1,085 feet elevation. While that’s 5 feet lower than the lake
stood at the end of 2019, it’s still 10 feet higher than the
water level that would trigger the first major shortage,
slicing more than 520,000 acre feet of water, roughly one-third
of the state’s total supply.
The U.S. Bureau of Reclamation released projections Friday that
suggest Lake Powell and Lake Mead will dip 16 feet and 5 feet,
respectively, in January from levels recorded a year earlier.
Despite the dip, Lake Mead would stay above the threshold that
triggers severe water cuts to cities and farms, giving
officials throughout the Southwest more time to prepare for the
future when the flow will slow.
Arizona, Nevada and Mexico will again receive less water from
the Colorado River next year under a set of agreements intended
to help boost the level of Lake Mead… The federal Bureau of
Reclamation released projections Friday showing that Lake Mead,
the nation’s largest reservoir, will be at levels next year
that continue to trigger moderate cutbacks in the two U.S.
states and Mexico.
The U.S. Bureau of Reclamation is expected to release
projections Friday that suggest Lake Powell and Lake Mead will
dip slightly in 2021. … Despite the dip, Lake Mead’s levels
are expected to stay above the threshold that triggers
mandatory water cuts to Arizona and Nevada, giving officials
throughout the Southwest more time to prepare for a future when
the flow will slow.
Water-efficient succulents and nitrogen-fixing tree legumes may
take five to 12 years to produce their first nutritional
harvests. Nevertheless, they can produce more edible biomass
over a decade with far less water than that used by
conventional annual crops, while sequestering carbon into the
soil to mitigate climate change…
We deserve complete, dependable information and accurate cost
data including well-reasoned analysis that demonstrates the
need and economic viability of the pipeline. Instead, studies
by the Utah Division of Water Resources and the Washington
County Water Conservancy District are biased, incomplete and do
not fairly consider feasible, much less costly alternatives.
The newly passed Drought Contingency Plan spurred additional
conservation and left more water in the lake. An unusually wet
year also helped, because it allowed states to fall back on
other supplies. But the fundamental problem remains: The river
still isn’t producing the amount of water we use in a typical
year. We’re still draining the mighty Colorado.
The average annual flow of the Colorado River has decreased 19
percent compared to its 20th century average. Models predict
that by 2100, the river flow could fall as much as 55 percent.
The Colorado River, and the people it sustains, are in serious
trouble.
Legal scholars believe that the Lake Powell pipeline would
likely violate the 1922 Colorado River Compact as a
transfer of upper basin water (WY, UT, CO, NM) for lower basin
use (CA, NV, AZ). The lower basin has priority, and the compact
arguably prohibits transfers from the upper to lower basin
absent explicit congressional authorization
The Imperial Irrigation District and farmer Michael Abatti have
been locked in a years-long legal battle with as many twists as
the river over which it has been fought. The saga might finally
come to an end, though, after a California appellate court
handed down a ruling on Thursday that found IID is the rightful
manager of the portion of the Colorado River guaranteed to the
Imperial Valley.
The Imperial Irrigation District has filed its opening brief in
a case against the Metropolitan Water District of Southern
California that it launched last year in an attempt to halt the
implementation of the Lower Basin Drought Contingency Plan for
the Colorado River. IID wants to see it paused until the Salton
Sea is also considered.
The public last week had its first opportunity to pepper
officials with questions about the Lake Powell Pipeline’s
recently-released draft environmental impact statement, a
313-page document from the Bureau of Reclamation examining how
the controversial project could impact a myriad of resources in
several scenarios.
Researchers in the Grand Canyon now spend weeks at a time,
several times a year, monitoring humpback chub, which has
become central to an ecosystem science program with
implications for millions of westerners who rely on Colorado
River water.
In 2013, Nevada was in a dry spell in more ways than one. The
aftershocks of the Great Recession lingered, and the state was
in the midst of 20 years of drought. In response, the Desert
Research Institute branch in Las Vegas, with funding through
the Governor’s Office of Economic Development’s Knowledge Fund,
launched a startup called WaterStart, which set out to deploy
new water technologies and make the Silver State a hub for
water innovation.
After several years of experimentation, scientists have
engineered thale cress, or Arabidopsis thaliana, to
behave like a succulent, improving water-use efficiency,
salinity tolerance and reducing the effects of drought. The
tissue succulence engineering method devised for this small
flowering plant can be used in other plants to improve drought
and salinity tolerance with the goal of moving this approach
into food and bioenergy crops.
The Trump administration has decided a chemical with a
notorious legacy in Nevada will not be regulated in drinking
water, but state officials say the reversal of the Obama-era
policy shouldn’t result in any decline in drinking water
standards across the state.
Arizona, New Mexico, Colorado, California, Utah, Wyoming and
Nevada have been operating under a set of guidelines approved
in 2007. Those guidelines and an overlapping drought
contingency plan will expire in 2026. Arizona water officials
are gathering Thursday to start talking about what comes next,
while other states have had more informal discussions.
While these remarkable giants have been only a distant memory
in most of their range, recently, fish carrying the ancestral
genes of Pyramid Lake Lahontan cutthroat trout migrated to the
waters of the Truckee River in 2014 to spawn for the first time
in 80 years. The return of these fish … represents the
culmination of years of conservation efforts by local, state,
and federal agencies, as well as the Pyramid Lake Paiute Tribe.
There’s a reckoning coming, unless cities and farm districts
across the West band together to limit consumption. The coming
dealmaking will almost certainly need to involve the river’s
largest water user, the Imperial Irrigation District. But at
the moment, it’s unclear to what extent the district actually
controls the Imperial Valley’s Colorado River water. That was
the issue debated in a San Diego courtroom last week
Nevada restricted groundwater pumping Tuesday in an area north
of Las Vegas, potentially killing a real estate project that
threatens an endangered fish clinging to existence in a handful
of spring-fed desert pools…
Nevada is in a new era of water management. As the driest state
in the nation, responsible and sustainable management of
Nevada’s limited water resources is the foremost priority of
the Nevada Division of Water Resources. As part of this
commitment, Monday the Nevada State Engineer issued Order No.
1309 for one of Nevada’s most important and unique hydrographic
basins called the Lower White River Flow System.
Although the Clean Water Act will still protect heavily used
waterways in Nevada, including the Colorado River and the
Truckee River, it excludes many wetlands and most seasonal
streams. As a result, the rule has set off a flurry of legal
challenges from environmental groups. And in recent months,
several Democrat-led Western states, including Colorado,
California and New Mexico, have sued the Trump administration
to challenge the final rule. Nevada has not joined those suits.
In his time with the commission, which has the responsibility
for applying the boundary and water treaties between the United
States and Mexico, the two nations have taken huge steps
forward in assuring that commitments to the primary binational
water agreement in the Southwest – the 1944 Mexico-U.S. Water
Treaty – were faithfully upheld.
When former Interior Secretary Bruce Babbitt suggested in a
recent opinion piece that a portion of agricultural water
rights on the Colorado River should be transferred to urban
areas, it no doubt conjured up some strong emotions… But
Babbitt’s proposal makes sense and he is right about the need
to recognize the mismatch in population between the urbanized
West and rural areas where most of the basin’s water is
allocated.
On May 21, the Southern Nevada Water Authority board of
directors voted to indefinitely defer its groundwater
development project, which opponents had dubbed the “water
grab.” The unanimous vote brought an end to more than three
decades of acrimonious battle with the Great Basin Water
Network.
While Imperial Irrigation District has the largest right within
California, it was not the Imperial Valley that was responsible
for California’s overuse. That was the Metropolitan Water
District. We are among the very oldest users on the Colorado
River and have built a community, ecology, and way of life here
in the desert dependent upon the waters of the Colorado that
have sustained us since 1901.
Las Vegas water use decreased rapidly starting in mid-March,
around the same time that Gov. Steve Sisolak instituted a
stay-at-home order and closed most nonessential businesses. But
since late April, it has gradually been increasing to more
typical levels, Las Vegas Valley Water District data shows.
Across the Southwest, investors are banking on water scarcity.
They are buying up farms and ranches as states explore new
programs that could make it easier to sell and transfer water.
… Today a new type of investor has started eyeing water in
the basin, less intent on building a new community than on
supporting existing ones within one of the nation’s fastest
growing states.
The imbalance on the Colorado River needs to be addressed, and
agriculture, as the biggest water user in the basin, needs to
be part of a fair solution. But drying up vital food-producing
land is a blunt tool. It would damage our local food-supply
chains and bring decline to rural communities that have
developed around irrigated agriculture.
This winter’s decent snowfall has turned into an abysmal runoff
on the Colorado River, thanks to the dry soils heading into the
winter, along with a warm spring. … Our bigger concern is
what happens next year. Are we headed for a multi-year drought?
Citing conservation gains and a third straw to the bottom of
Lake Mead, the Southern Nevada Water Authority on Thursday
voted to shelve a proposal for a multi-billion pipeline that
would have moved water from Northern and Eastern Nevada to Las
Vegas. The vote means the pipeline staunchly opposed by rural
communities, American Indian tribes and conservationists is
dead – or at least going into a long, deep coma.
The Southern Nevada Water Authority voted Thursday to withdraw
all pending groundwater importation applications, return a
right-of-way associated with groundwater importation plans to
the Bureau of Land Management and take other actions to move
the multibillion-dollar groundwater development project —
sometimes referred to as the water pipeline project — into
“indefinite deferred status.”
Cornell engineers have used advanced modeling to simulate more
than 1 million potential futures – a technique known as
scenario discovery – to assess how stakeholders who rely on the
Colorado River might be uniquely affected by changes in climate
and demand as a result of management practices and other
factors.
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.
As of Monday, the National Oceanic and Atmospheric
Administration’s forecast for this year’s expected water
supplies in the Colorado River is at 59% of average. That’s not
good news. If that prediction proves true, this will be one of
the driest water years since Lake Powell was constructed nearly
60 years ago.
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..
Nevadans and Utahns won a major economic and environmental
victory in mid-April that will help protect air quality along
the Wasatch Front and the Great Basin’s fragile water supply ––
including Great Salt Lake.
Southern Nevada has been in a drought for about 20 years. But
now, we’re learning this isn’t just drought – it’s a
megadrought. That’s a one in 500 years drought.
The University’s Adrian Harpold recently led a team in
developing a modeling tool to focus on the issue of water
quantity. The tool predicts how different approaches to
thinning the forest impact snowpack accumulation in Lake Tahoe,
which controls how much water is available for downstream
communities such as Reno.
Rural and urban Nevada can both rest a little easier now that
the massive pipeline project is not at the forefront of the
Southern Nevada Water Authority’s plans. But there is still
plenty of work to do to protect and expand the water supply in
Las Vegas while doing the same in rural parts of the state.
It has been 30 years since the last time a dam was seriously
considered on the East Fork [of the Carson River] as a means to
reduce flooding and increase water for agriculture and other
uses. … The East Fork begins near the base of Sonora Peak in
California. The river’s upper gorge was carved out by a 16-mile
glacier coming off the 11,500-foot high mountain. It is one of
only two major free-flowing rivers in the Eastern Sierra.
The US Bureau of Reclamation is to resume a seismic safety
modification project at Boca Dam near Truckee in California
today, following its seasonal closure in November 2019, with
social distancing guidelines recommended by the Centers for
Disease Control and Prevention and other COVID-19 precautions
to be followed during construction.
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.
We know one thing for sure: We need to wash our hands well and
often. And for that we need clean, running water. But so far
the federal legislative responses to the novel coronavirus
crisis have not included financial support for water utilities,
most of which are public agencies. And there’s been no federal
mandate to prevent water shutoffs for households unable to pay
their bills.
Opponents of the mine expansion in Elko County are worried
about phase two of the Long Canyon Mine near Wells that
includes a dewatering plan that would pump billions of gallons
of water annually from an aquifer deep below the Pequop Range
and Goshute Valley.
The models show drought is expected to keep its hold over the
mountains along the New Mexico-Colorado border that feed the
Rio Grande, while California, Nevada and other southwestern
states aren’t likely to see a reprieve from dry conditions
through June.
Without the river, there would not have been an Emigrant Trail
through this site, gold would not have been discovered in
Dayton and who knows when the Comstock Lode would have been
discovered and Nevada might not even be Nevada today!
This report, “Scaling Corporate Water Stewardship to Address
Water Challenges in the Colorado River Basin,” examines a set
of key corporate water stewardship actions and activities, with
associated drivers and barriers, to identify how the private
sector could help tackle Colorado River water challenges.
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.
The latest research about the Colorado River is alarming but
also predictable: In a warming world, snowmelt has been
decreasing while evaporation of reservoirs is increasing. Yet
no politician has a plan to save the diminishing Colorado
River.
A District Court judge has once again scuttled the Southern
Nevada Water Authority’s plans to obtain and pump rural
groundwater about 300 miles from eastern Nevada, prompting one
Clark County commissioner to call on the water authority “to
look in a different direction.”
A $3 billion package of water projects recommended for approval
by the Southern Nevada Water Authority this month could raise
average residential bills by $10, while providing a boost to
the Apex Industrial Park in North Las Vegas.
As the waters of Lake Mead have risen and fallen over the
years, the remains of the village of St. Thomas have
reappeared, then disappeared again, only to re-emerge years
later. It’s a sort of Brigadoon for the southwestern United
States.
The Nevada Supreme Court heard arguments Tuesday in a case
weighing how state regulators should consider “public trust”
values — the environment or recreation — when the
sustainability of lakes or rivers could be harmed by how the
state has allocated water rights.
A proposal to pump water out of Nevada’s fragile Walker Lake to
generate hydropower to sell in California won preliminary
approval from federal regulators. On Friday, the Federal Energy
Regulatory Commission issued a preliminary permit and granting
priority to file for the proposed Walker Lake Pumped Storage
Project.
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.
I have long argued that a robust governance network, both
formal and informal, around the management of the Colorado
River provides the necessary conditions for managing the
problems of the river’s overallocation and the increasingly
apparent impacts of climate change. … But as we approach the
negotiation of the next set of Colorado River management rules
– a process already bubbling in the background – it is not hard
to see how my thesis could break down.
The Nevada Supreme Court heard arguments Tuesday in a case
weighing how state regulators should consider “public trust”
values — the environment or recreation — when the
sustainability of lakes or rivers could be harmed by how the
state has allocated water rights.
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.
The Colorado River’s average annual flow has declined by nearly
20 percent compared to the last century, and researchers have
identified one of the main culprits: climate change is causing
mountain snowpack to disappear, leading to increased
evaporation.
The Bureau of Land Management may stop studying how its
long-term blueprints for millions of acres of public lands
would affect the environment, according to a document shared
with Bloomberg Environment. … The BLM may propose a land use
planning rule that will “remove NEPA requirements from the
planning regulations,” referring to the National Environmental
Policy Act,
The 2018 Four Corners drought — centered on the junction
between Arizona, Utah, Colorado and New Mexico — put the region
deep in the red. An abnormally hot spring and summer indicated
that climate change was clearly at work, but that was about as
much as most people could say… Climate scientists from UC
Santa Barbara have now distilled just how strong an effect
human-induced warming had on that event.
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…
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.
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.
The Lower Basin states of Arizona, California and Nevada need
to cut total water use by 18% from their 2000-2018 average to
bring Lakes Mead and Powell into a long-term state of balance,
says Brian Richter. Richter is president of the nonprofit group
Sustainable Waters and a former director and chief scientist
for the Nature Conservancy’s Global Water program.
The river is a powerful example of Mexico’s failure to protect
its environment: A New York Times analysis of 15 years of
efforts to clean up the Santiago found that attempts floundered
in the face of legal loopholes, deficient funding and a lack of
political will.
In theory, a demand management program would pay users to
conserve in the midst of a crisis in order to boost the river’s
big reservoirs. How it would work, who would participate and
how it would be funded are still unanswered questions. Another
concern is how to make the program equitable — so it doesn’t
burden one user over another.
The Colorado River Commission of Nevada unanimously voted this
week to intervene into a lawsuit between the U.S. Department of
the Interior and a group of environmental activists led by the
nonprofit Save the Colorado River. The lawsuit alleges the
department, in drafting a long-term plan for the Glen Canyon
Dam in northern Arizona, did not fully consider the impacts of
climate change…

nonprofit Save the Colorado River. The lawsuit alleges the
department, in drafting a long-term plan for the Glen Canyon
Dam in northern Arizona, did not fully consider the impacts of
climate change…
Federal water managers are about to start reexamining a
12-year-old agreement among Western states that laid down rules
for dealing with potential water shortages along the Colorado
River. Interior Secretary David Bernhardt said he asked the
Bureau of Reclamation to start the review at the beginning of
2020, rather than by the end of 2020, which is the deadline
under the existing agreement.

States in the U.S. West that have agreed to begin taking less
water next month from the drought-stricken Colorado River got
praise and a push for more action Thursday from the nation’s
top water official. U.S. Bureau of Reclamation Commissioner
Brenda Burman told federal, state and local water managers that
abiding by the promises they made will be crucial to ensuring
that more painful cuts aren’t required.
U.S. Bureau of Reclamation Commissioner Brenda Burman said
Wednesday that Nevada has been a national leader in water
conservation by reducing demand on the Colorado River and
investing in infrastructure over the past two decades. In Las
Vegas for the Colorado River Water Users Association’s annual
conference, Burman declined to say, however, whether she sees
Nevada’s share of the river’s water increasing…
Arizona, Nevada and Mexico will start taking less water from
the Colorado River in January as a hard-fought set of
agreements kicks in to reduce the risk of reservoirs falling to
critically low levels. The two U.S. states agreed to leave a
portion of their water allotments in Lake Mead under a deal
with California called the Lower Basin Drought Contingency
Plan, or DCP…
Net groundwater pumping peaked in 1968 at 86,000 acre-feet and
started to go down in the 1980s, ’90s and 2000s, according to
the state’s 2018 groundwater pumpage inventory for the aquifer.
Thanks to the water authority’s efforts to reduce pumping, only
10% of the water used in the valley now comes from groundwater,
while the rest comes from Lake Mead, Mack said.
As conventional wisdom has it, the states were relying on bad
data when they divided up the water. But a new book challenges
that narrative. Turn-of-the-century hydrologists actually had a
pretty good idea of how much water the river could spare, water
experts John Fleck and Eric Kuhn write in Science be Dammed:
How Ignoring Inconvenient Science Drained the Colorado River.
They make the case that politicians and water managers in the
early 1900s ignored evidence about the limits of the river’s
resources.
Native American tribes, environmentalists, state and federal
agencies, river rafters and others say they have significant
concerns about proposals to dam a Colorado River tributary in
northern Arizona for hydropower.
During days when solar panels feed more energy into the grid
than utilities want to buy, the projects would use the excess
power to pump water from Walker Lake or Pyramid Lake into the
newly constructed reservoirs. Once there, the water would sit
as a giant pool of potential energy. When demand for power
increased at night as solar production waned, the water could
be released downhill and run through a power plant.
Nevada’s director of the Department of Conservation and Natural
Resources said Nevada has already reached the point of
“critical mass” or the breaking point when it comes to the
problem of water scarcity. … “We are up against that much
strain in our water resources across the state,” Director Brad
Crowell said.
Ambiguity exists in the language of the river’s foundational
document, the Colorado River Compact. That agreement’s language
remains unclear on whether Upper Basin states, where the
Colorado River originates, are legally obligated to deliver a
certain amount of water over a 10-year period to those in the
Lower Basin: Arizona, California, and Nevada.
The Southern Nevada Water Authority is proposing a 10-year
marketing deal with the future Las Vegas Raiders that will pay
the NFL franchise more than $30 million in tax dollars over the
next decade, enabling the agency to use team logos and place
advertising in the $1.9 billion Allegiant Stadium.
After blurring the line between a private and public utility
for nearly two decades, the water district that serves the
world’s largest industrial park is looking to part ways with a
developer. That action comes after The Nevada Independent
reported this month that the public water district … is
operated by a private entity and governed by three board
members who report income from companies connected to Lance
Gilman, the face of the industrial park. The board members also
reside at Gilman’s brothel, the Mustang Ranch.
Declining flows could force Southwest water managers to
confront long-standing legal uncertainties, and threaten the
water security of Upper Basin states of Colorado, Wyoming, Utah
and New Mexico.
The problem in the 1920s was neither the lack of good science
nor the inability of decision-makers to understand the basin’s
hydrology. … In an era driven by politics of competition for
a limited supply of river water and federal dollars, those
decision-makers had the opportunity to selectively use the
available science as a tool to sell their projects and vision
for the river’s future to Congress and the general public.
In this episode, we explore a carcinogen called 1,2,3
Tetracholorpropane, which ended up in the water below
California’s Central Valley. … We also hear from John Hadder
and Dr. Glenn Miller, with Great Basin Resource Watch, about
how some of the groundwater in Nevada became contaminated due
to mining operations near Yerington.
The Southern Nevada Water Authority’s Las Vegas water grab and
pipeline –– which has been in various stages of development
since 1989 –– would forever tarnish public lands and waters in
Eastern Nevada and Western Utah. The idea is a direct
descendant to the Los Angeles Aqueduct.
Arizona’s portion of the Drought Contingency Plan became a
unique example in the basin of tribal leaders asserting
themselves in broader discussions about the river’s management.
… With the drought plan done, some tribal leaders say their
water rights can’t be ignored any longer.
Here’s the nut: Water supply in the Colorado River could drop
so far in the next decade that the ability of the Upper
Colorado River Basin states – Colorado, Utah, Wyoming, and New
Mexico – to meet their legal obligations to downstream users in
Nevada, Arizona, California, and Mexico would be in grave
jeopardy.
The Goshute, Ely and Duckwater Shoshone tribes all consider the
site, known as the swamp cedars, sacred and believe the trees
are threatened by a proposal to pipe groundwater to Las Vegas.
… Tribal members are pushing for greater recognition of
the site in order to strengthen their case against Southern
Nevada Water Authority’s proposal to pipe groundwater
from the area to Las Vegas.
Shrinking water resources due to climate change are driving
major declines in Mojave Desert bird populations, according to
a new study from researchers at University of California,
Berkeley.
Officials who oversee a water district exempt from state
regulation work and live at a brothel owned by the public face
of the world’s largest industrial park, raising questions about
whether governmental powers such as eminent domain are being
wielded by a private entity.
EDF created an online story map … to provide a more holistic
view of groundwater supplies and challenges in the seven-state
Colorado River Basin (Arizona, California, Colorado, New
Mexico, Nevada, Utah and Wyoming), drawing from recent
research. Here are four key highlights from the story map that
demonstrate the importance of groundwater and the challenges of
groundwater management in the arid West:
Almost 50 years after the Lahontan cutthroat trout was listed
under the Endangered Species Act, agencies are investing in a
game-changing, fish-friendly infrastructure project at Derby
Dam to help bring back the legendary fish to the Truckee River.
Announced on Sept. 11, 2019, construction of a fish passage
structure will allow Lahontan cutthroat trout to complete their
natural migration, swimming back and forth between Pyramid Lake
and historic spawning grounds.
The Colorado River serves over 35 million Americans before
reaching Mexico – but it is dammed at the border, leaving
locals on the other side with a dry delta.
We now have an opportunity to build on the successful Arizona
process that led to the DCP signing. Arizona is stronger
together. And that will serve us well as we work toward the
next step – maintaining a stable, healthy Colorado River system
as we face a hotter and drier future.
Lake Powell’s long decline may be on hiatus after this year’s
snowy winter, but activists still are raising concerns that
climate change could render Glen Canyon Dam inoperable. This
time, they are taking their concerns to court, asking a federal
judge to invalidate the federal Bureau of Reclamation’s 20-year
operating plan for the towering dam..
As populations in the West rise, managers of our precious water
supplies have to figure out how to deal with increasing demand
in the midst of climate change. In Southern Nevada, we rely on
the Colorado River. But the Truckee River is the lifeline in
Northern Nevada, and climate change is affecting them in a much
different way.
There was more buzz this week at two big Colorado River Basin
events about the idea of a “grand bargain” to deal with coming
collisions between water overallocation and the Law of the
River.
Total and per-capita water use in Southern Nevada has declined
over the last decade, even as the region’s population has
increased by 14%. But water use among the biggest water users —
some of the valley’s wealthiest, most prominent residents — has
held steady.
There is not enough water to support important wetlands and
springs in a semi-arid desert ecosystem that straddles the
Nevada-Utah border if all permitted and proposed groundwater
rights are put to use, according to a U.S. Geological Survey
study of the Snake Valley. There also may not be enough
groundwater to satisfy the desires of the Las Vegas area, whose
water agencies have eyed the valley for decades…
The Colorado River Basin’s 20 years of drought and the dramatic
decline in water levels at the river’s key reservoirs have
pressed water managers to adapt to challenging conditions. But
even more extreme — albeit rare — droughts or floods that could
overwhelm water managers may lie ahead in the Basin as the
effects of climate change take hold, say a group of scientists.
I’ve spent half a day tormented by a problem that has already
tormented me many times before in my career: Where can one find
a Colorado River Basin map that is accurate? It seems like such
a simple task, but as others have noted before, it is an
ongoing problem. The list of problem areas is long, and many
seem to have a strong political motivation.
Nevada and Arizona, concerned that a 20-year drought has dried
up much of the river, are trying to rein in water use in an
effort to save the disappearing river. The river’s water levels
next year are projected to be just below the threshold of 1,090
feet laid out in the Drought Contingency Plan that was signed
earlier this year…
A quarter-cent sales tax raising $100 million annually for
water and wastewater projects will remain in place indefinitely
following a decision Tuesday by the Clark County Commission.
… The 6-1 vote removes a sunset clause that would have made
the tax expire in 2025.
Water users in the Colorado River Basin have survived the
drought through a combination of water storage infrastructure
and voluntary actions to protect reservoir storage and water
supply. Adoption of drought contingency plans this summer,
developed over years of collaborative negotiation, takes the
next step by implementing mandatory action to reduce risk and
protect limited water supplies.
There are a lot of reasons our watershed is unique. It’s a high
elevation terminal watershed, what could be more special? Well,
another contributing factor is that the terminus of the Truckee
River watershed exists on the largest Native American
Reservation in Nevada.
ASU Now spoke to Sarah Porter, director of the Kyl Center for
Water Policy at ASU’s Morrison Institute for Public Policy,
about the cutbacks and what they will mean for Arizona’s
agriculture and the state’s roughly 7 million residents.
Environmental groups are raising concerns over a provision in
draft legislation they believe could exempt the Las Vegas
pipeline — a proposal to pump eastern Nevada groundwater about
300 miles to Southern Nevada — from further litigation and
federal environmental review.
The Colorado is the most significant water supply source in the
West, but it carries an annual salt load of nine to 10 million
tons, said Don Barnett, executive director of the Colorado
River Basin Salinity Control Forum. … For the past 40 years,
the the forum has been “silently working away” at improving
water quality and lowering salt content on the Colorado, which
supplies water to 40 million people in seven states and Mexico.
Rocky Mountain water managers worried about climate-driven
depletion across the Colorado River Basin are mulling a “grand
bargain” that would overhaul obligations among seven
southwestern states for sharing the river’s water. This
reflects rising concerns that dry times could turn disastrous.
Just a few months after completing the Drought Contingency Plan
for the Colorado River states, water managers in the southwest
will likely have to implement it starting in 2020. That’s
according to new projections for the levels of key reservoirs
in the southwestern river basin, and Arizona is first in line
to take water cutbacks.
Arizona and Nevada will face their first-ever cuts in Colorado
River water next year, but the changes aren’t expected to be
overly burdensome for either state.
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.
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
term.
With big western cities clamoring for a share of the
river’s diminishing supply, desert farmers with valuable claims
are making multimillion dollar deals in a bid to delay the
inevitable. … But if the river’s water keeps
falling, more radical measures will be needed to protect
what remains.
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.
Described in a comprehensive new study published Wednesday in
the journal Science Advances, scientists now understand the
causes of the megadroughts common during the medieval period.
With climate change, they predict more megadroughts in the
future.
On July 5, for the first time since Europeans settled the
remote and scenic Walker Basin, there’s water flowing through
the Walker River exclusively for the benefit of the lake’s fish
and wildlife.
Water managers on the Colorado River are facing a unique
moment. With a temporary fix to the river’s scarcity problem
recently completed, talk has begun to turn toward future
agreements to manage the water source for 40 million people in
the southwestern U.S. … Some within the basin see a window of
opportunity to argue for big, bold actions to find balance in
the watershed.
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.
In black and white, John Trotter documents the use of water
from the Colorado River, tackling the social, political, and
environmental impact of the way it’s dealt with. Spanning over
years and kilometres, his ongoing essay is a dire political
outcry.
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
temporary problem.
The unusually wet winter (with an assist from new Colorado
River Drought Contingency Plan water reduction rules) has
substantially reduced the near-term scare-the-crap-out-of-me
risks on the Colorado River for the next few years, according
to new Bureau of Reclamation modeling.
It will take as many as 13 water years exactly like this one to
erase the impacts of long-term drought in the West, Colorado
River District engineers say.
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.
The Lower Basin will not drop into a Tier One shortage next
year because Lake Mead will almost certainly remain above 1,075
feet in elevation. At the same time, Mead will likely remain
under 1,090 feet. That triggers a Tier Zero shortage. “Under
Tier Zero conditions, Arizona takes a reduction of 192,000
acre-feet in its annual Colorado River entitlement,” said
Suzanne Ticknor, assistant general manager at the Central
Arizona Project.
Leaving more water in the Colorado River Basin could help
rivers resume their natural role. But amid this push for upper
basin residents to use less, Colorado’s booming Front Range
economy is driving cities in the opposite direction: of
manipulating rivers more by installing new dams, reservoirs and
diversions.
The Colorado River Drought Contingency Plan, divided into plans
for the river’s upper and lower basins, is the product of years
of interstate negotiations, business transactions and political
dealings. What, though, does it mean for Nevada and other
Western states as a whole?
Most of the seven states that get water from the Colorado River
have signed off on plans to keep the waterway from crashing
amid a prolonged drought, climate change and increased demands.
But California and Arizona have not, missing deadlines from the
federal government.
The question of whether the Colorado River system is a reliable
source of water for the future was the topic of a presentation
held at the Washington County Water Conservancy District on
Thursday. … Utah is entitled to 23%, or about 1.4 million
acre feet under the compact. Utah currently uses 1 million acre
feet, Millis said. This leaves the state with 400,000 acre feet
to left to develop.
The states that share the river completed a drought plan
earlier this year that brings them closer to living within
currently available supplies, and a new round of negotiations
on long-term management of the river is due to begin next year.
However, a new report warns that planning for gradually
declining water supplies, as difficult as that is, may not be
enough to adequately prepare for the future.
States that share the river’s water finalized a big agreement
last month, but an even larger challenge determining the
river’s future is just around the bend, expert John Fleck
explains.
Rather than unquestioningly celebrating Powell and his legacy,
this year gives us the chance to think about a couple of
points: First, how are we telling Powell’s story now, and how
have we told it in the past? Is it, and has it been, accurate
and useful? Second, whose stories have we excluded, ignored,
and forgotten about in the focus on Powell?
Nevada ranchers, environmental groups and American Indian
tribes are sounding the alarm over legislation they say could
drain the water supply from rural areas throughout the state.
They’re worried about Assembly Bill 30 in the Nevada
Legislature after negotiations over arcane language in the bill
broke down in recent days.
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
reductions.
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
levels.
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.
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.
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
Plan.
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
water law.
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.
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.
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.
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…
Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.
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.
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.
The giant reservoir, formed by Glen Canyon Dam, was under 40
percent full the last week of April. And a lot of water is
still being released from the reservoir, more demands on the
water are expected, and the water supply above the reservoir,
in the sprawling Colorado River system, is expected to
decrease.
Set to expire in 2026, the current guidelines for water
deliveries and shortage sharing, launched in 2007 amid a
multi‐year 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…
DCP puts safeguards in place to help manage water use now and
better deal with a potential shortage. Utah, Arizona and the
five other Colorado River basin states wisely chose to include
conservation measures in the DCP — and shared in their
sacrifice to avoid costly litigation and imposed cuts. Congress
and the states should be commended for this bipartisan,
collaborative process.
Some lawyers say the Drought Contingency Plan, or DCP, may be
built on shaky legal ground and could be vulnerable to
litigation — depending on how the Bureau of Reclamation
implements it. One California water district has already sued
to block it.
Tracy Hall says she’s lucky to have friendly neighbors who
allow her to live in an RV on their property while water laps
at a temporary barrier on the edge of her property. But Hall
and others are tired of the disruption to their lives that
started more than two years ago when the formerly dry lake in
Lemmon Valley filled with stormwater runoff and urban effluent.
A federal official is attempting to “obstruct” the flow of
water to restore habitat at Walker Lake, the conservancy
responsible for administering federal restoration funds alleged
in District Court last week. After years of litigation, lawyers
for the Walker Basin Conservancy said that “at some point, the
court must put a stop to the federal water master’s
obstruction.” The receding desert lake outside of Hawthorne is
fed by the Walker River, which rises in California and snakes
through Western Nevada.
For the third year in a row, Lake Tahoe is expected to fill.
This is noteworthy for the sixth-largest lake in the United
States that flirted with record-low levels amid a five-year
drought that ended in 2017.
The Colorado River Sustainability Campaign has been an
important behind-the-scenes player for environmentalists
working on the waterway, which provides water to 40 million
people. … When asked who funds his project, Sam Tucker listed
five foundations. Those foundations’ grant databases showed
that his campaign has received at least $8.6 million since
2016. … Almost half — $4 million — of the campaign’s money
came from one source: the Walton Family Foundation. (Second of
two parts.)
Arizona’s top water official says a lawsuit filed Tuesday by
California’s Imperial Irrigation District could pose a threat
to the newly approved multistate drought contingency plan. But
Tom Buschatzke, director of the Department of Water Resources,
said he’s not worried the plan will fall apart — at least not
yet.
There are at least six high-profile projects in Utah, Colorado,
and Wyoming that combined could divert more than 300,000
acre-feet of water from the beleaguered Colorado River. That’s
the equivalent of Nevada’s entire allocation from the river.
These projects are in different stages of permitting and
funding, but are moving ahead even as headlines about the
river’s dwindling supply dominate the news.
An unlikely advocate seems to be around every bend of the
Colorado River these days: the Walton Family Foundation. The
$3.65 billion organization launched by Walmart founder Sam
Walton has become ubiquitous in the seven-state basin that
provides water to 40 million people, dishing out $100 million
in grants in the last five years alone. … The foundation’s
reach is dizzying and, outside the basin, has received scant
attention. (First of two parts.)
The petition, filed in Los Angeles Superior Court,
alleges violations of the California Environmental Quality
Act by the Metropolitan Water District of Southern California,
and names the Coachella Valley, Palo Verde and
Needles water districts as well. It asks the court to
suspend the Lower Basin Drought Contingency Plan until a
thorough environmental analysis has been completed.
