The construction of Glen Canyon Dam in north-central Arizona also
created Lake Powell. Lake Powell serves as a holding tank for the

Avoiding a long-expected crisis on the Colorado River, a water
source for 40 million people, is coming down to a final few
days of frenzied negotiations. A 19-year drought and decades of
overuse have put a water shortfall on the horizon. If
California and six other states, all with deeply entrenched
interests, can’t agree on a plan to cut their water consumption
by Jan. 31, the federal government says it will step in and
decide the river’s future.
Water conservation in the Las Vegas Valley is imperative as the
city continues to grow. The resources provided by the Colorado
River are stretched thin, as the river is responsible for
supplying the majority of the water to Southern Nevada, six
other states—California, Arizona, New Mexico, Wyoming, Utah,
Colorado—and Mexico. Combine these existing allotments with
drought conditions that have reduced the river’s average flows
by 30 percent annually, and it’s clear that Las Vegas must be
proactive in its conservation efforts.
In Arizona, the Colorado River Drought Contingency Plan now
hinges on the approval of tribal nations. The plan is meant to
levy water cuts to seven Western states in order to prevent the
river and its reservoirs from reaching critical levels — but
after a state lawmaker introduced legislation that undermines
parts of the Gila River Indian Community’s water settlement,
the tribe has threatened to exit the plan. Without tribal
buy-in, Arizona’s implementation design will collapse….
Federal Reclamation Commissioner Brenda Burman has drawn a line
in the sand for Arizona and other Western states: Finish a deal
to take less water from the Colorado River by Thursday, or the
federal government will be forced to step in and decide how to
prevent reservoirs from falling to critical levels. … The
plan’s success or failure will turn on the actions of a
few key players, including leaders of the Legislature, tribes,
farmers, cities and the state’s water managers.
The Colorado River is not meeting its obligations.
Its Lake Powell bank account is in danger of running
dry. A 97-year-old agreement demands that the river
deliver 5.2 trillion gallons of water to seven states and
Mexico each year. That isn’t happening, and now — in the age of
climate change — the chance of ever meeting that demand is
fading. As a result, Utah’s plan to take more of its
Colorado River water — by building a pipeline from Lake Powell
to St. George — may be fading, too.
Arizona’s water leaders and lawmakers are running out of time
to complete the state’s Drought Contingency Plan, a
blueprint for how Arizona water users would share a likely
shortage on the Colorado River. … There are a lot of
moving parts to understand and a lot of concepts that may seem
overwhelming. Here are the things you need to know in advance
of the Jan. 31 deadline to finish the plan.
The restoration site is one of three south of the
U.S.-Mexico border, in the riparian corridor along the last
miles of the Colorado River. There, in the delta, a small
amount of water has been reserved for nature, returned to
an overallocated river whose flow has otherwise been
claimed by cities and farms. Although water snakes through
an agricultural canal system to irrigate the restoration sites,
another source is increasingly important for restoring these
patches of nature in the delta’s riparian corridor:
Arizona lawmakers and the governor are under the gun to come up
with a Drought Contingency Plan to deal with possible Colorado
River water shortages. Get an update from Kathleen Ferris of
the Kyl Center for Water Policy at Arizona State University’s
Morrison Institute for Public Policy. This Arizona Horizon
segment is part of Elemental: Covering Sustainability, a
multimedia collaboration between public radio and public
television stations in Arizona, California and Colorado.
The Gila River Indian Community is threatening to blow up the
drought-contingency plan because of efforts it says will
undermine its claim to water rights. House Speaker Rusty Bowers
is proposing changes to state laws in a way he said will
protect the rights of farmers in the Safford Valley who have
been “scratching it out” to water from the Gila River. But
attorney Don Pongrace, who represents the Gila River Indian
Community, said … courts have ruled those rights — and the
water that goes with it — belong to the tribe.
With the Southwest locked in a 19-year drought and climate
change making the region increasingly drier, water managers and
users along the Colorado River are facing a troubling question:
Are we in a new, more arid era when there will never be enough
Longstanding urban-rural tensions over a proposed drought plan
have escalated after Pinal County farmers stepped up their
request for state money for well-drilling to replace Colorado
River water deliveries. “Enough is enough,” responded 10
Phoenix-area cities through a spokesman. They say the state has
already pledged millions to the farms for well drilling, and
plenty of water to boot.
Without a change in how the Colorado River is managed, Lake
Powell is headed toward becoming a “dead pool,” essentially
useless as a reservoir while revealing a sandstone wonderland
once thought drowned forever by humanity’s insatiable desire to
bend nature to its will. … Absent cutbacks to deliveries
to the Lower Basin, a day could come when water managers may
have little choice but to lower the waters that have inundated
Utah’s Glen Canyon for the past half-century.
With Lake Mead now 39 percent full and approaching a first-ever
shortage, Western states that rely on the Colorado River are
looking to Arizona to sign a deal aimed at reducing the risk of
the reservoir crashing. The centerpiece of Gov. Ducey’s
proposed legislation is a resolution giving Arizona Department
of Water Resources Director Tom Buschatzke the authority to
sign the Drought Contingency Plan. The package of proposed
bills also would appropriate $35 million and
tweak existing legislation to make the plan work.
The draft legislation compiled by the Department of Water
Resources looks similar to how water leaders described the
measures at a Drought Contingency Plan Steering Committee
meeting last week. … But the legislation as drafted
barely delves into the nitty-gritty details of a far more
complex intrastate agreement that Arizona water users have been
hashing out for months.
A proposed Colorado River drought plan that will cost well over
$100 million is just the beginning of what’s needed to protect
the over-allocated river, says Bruce Babbitt, the former
governor who rammed through Arizona’s last big water
legislation nearly four decades ago. After Gov. Doug Ducey
urged legislators to “do the heavy lifting” and pass the
proposed drought-contingency plan for the Colorado, Babbitt
said Monday that authorities will have to start discussing a
much longer-term plan immediately after it’s approved.
Following one of the hottest and driest years on record, the
Colorado River and its tributaries throughout the western U.S.
are likely headed for another year of low water. That’s
according to a new analysis by the Western Water Assessment at
the University of Colorado Boulder. Researcher Jeff Lukas, who
authored the briefing, says water managers throughout the
Colorado River watershed should brace themselves for diminished
streams and the decreasing likelihood of filling the reservoirs
left depleted at the end of 2018.
Arizona legislators and staff are attending closed-door primers
on water policy in advance of a critical January 31 federal
deadline for the state to approve the Drought Contingency Plan.
The first of three meetings occurred on Friday afternoon and
lasted two and a half hours. The session was led by Central
Arizona Project general manager Ted Cooke and Arizona
Department of Water Resources Director Tom Buschatzke.
As the Southwest faces rapid growth and unrelenting drought,
the Colorado River is in crisis, with too many demands on its
diminishing flow. Now those who depend on the river must
confront the hard reality that their supply of Colorado water
may be cut off.
Up against a federal deadline to approve a Colorado River
drought plan — a “generational change” in Arizona water
management — four key legislators say they’re optimistic
they’ll meet it. Led by House Speaker Rusty Bowers, a Mesa
Republican, they see the Legislature as ready — finally — to
officially endorse the plan. That’s even though competing water
interest groups still have highly visible disagreements about
Gov. Doug Ducey will use his fifth State of the State speech
Monday, Jan. 14, to try to corral the votes to approve a
drought-contingency plan in the next 17 days or risk federal
intervention. “We’re in a position now where we have a sense of
urgency and focus on Arizona’s water situation,” the governor
told the business community Friday in previewing the speech
that kicks off the legislative session.
The Colorado River may not look like it, but it’s one of the
world’s largest banks. The river is not only the source of
much of the American West’s economic productivity – San Diego,
Phoenix and Denver would hardly exist without it – but its
water is now the central commodity in a complex accounting
system used by major farmers and entire states. … This
month, the nation’s largest water agency, the Metropolitan
Water District, began what amounts to a run on the bank.
With a federal deadline to sign a Colorado River drought deal
three weeks away, Arizona water managers are still
grappling with several unresolved issues that could get in the
way of finishing an agreement. The outstanding issues,
some of which are proving contentious, range from developers’
concerns about securing future water supplies to lining up
funding for Pinal County farmers to drill wells and begin to
pump more groundwater.
First, the good news: The negotiators of Arizona’s Drought
Contingency Plan have crafted the most detailed, concrete
proposal to date laying out how Arizona will deal
with expected cutbacks to its supply of Colorado
River. Now, the bad: The partial shutdown of the federal
government is squeezing these negotiators.
Gov. Doug Ducey used his second inaugural speech Monday to
exhort lawmakers and others with a claim to Colorado River
water to approve a drought contingency plan before a solution
is imposed by the Bureau of Reclamation. “It’s simple: Arizona
and our neighboring states draw more water from the Colorado
River than Mother Nature puts back,” the governor told his
audience. “And with critical shortfall imminent, we cannot kick
the can any further.”
A team of researchers concludes that the ongoing drought across
the western U.S. rivals most past “megadroughts” dating as far
back as 800 A.D. — and that the region is currently in a
megadrought. Using tree ring data as a proxy for drought
conditions, the researchers say the current drought ranks
fourth worst among comparable 19-year periods of megadroughts
of the past 1,200 years.
It has been called speculative, foolhardy and overly expensive,
but Aaron Million’s plan to pump water from the Utah-Wyoming
border to Colorado’s Front Range just won’t dry
up. Now seeking water rights from the Green
River in Utah for a new version of his plan, Million thinks he
has fashioned a winning proposal to feed Colorado’s thirsty,
Colorado River water managers were supposed to finish drought
contingency plans by the end of the year. As it looks now,
they’ll miss that deadline. If the states fail to do their job,
the federal government could step in. Luke Runyon, a
reporter with KUNC who covers on the Colorado River Basin
recaps what’s been happening and why it’s so important.
As stakeholders labor to nail down
effective and durable drought contingency plans for the Colorado
River Basin, they face a stark reality: Scientific research is
increasingly pointing to even drier, more challenging times

Water managers from seven Southwestern states that depend on
the Colorado River are close but haven’t finalized an
unprecedented drought contingency plan they may have to enact
in 2020. The federal government’s top water official, Brenda
Burman, is expected to urge action Thursday at a Colorado River
Water Users Association conference in Las Vegas where a pact
was supposed to be signed.
A property tax hike could be coming to Washington County, with
water managers saying they need to increase revenues to cover
the costs of developing new water resources for the St. George
area, including the proposed Lake Powell Pipeline. … A public
hearing on the plan is slated for 6 p.m. Wednesday at the
Washington County Water Conservancy District office.
With drought entering a second decade and reservoirs continuing
to shrink, seven Southwestern U.S. states that depend on the
overtaxed Colorado River for crop irrigation and drinking water
had been expected to ink a crucial share-the-pain contingency
plan by the end of 2018. They’re not going to make it — at
least not in time for upcoming meetings in Las Vegas involving
representatives from Arizona, California, Colorado, Nevada, New
Mexico, Utah, Wyoming and the U.S. government, officials say.
As the Colorado River Basin becomes
drier and shortage conditions loom, one great variable remains:
How much of the river’s water belongs to Native American tribes?
Native Americans already use water from the Colorado River and
its tributaries for a variety of purposes, including leasing it
to non-Indian users. But some tribes aren’t using their full
federal Indian reserved water right and others have water rights
claims that have yet to be resolved. Combined, tribes have rights
to more water than some states in the Colorado River Basin.
Western Slope water managers have doubled down on their
position that they will oppose federal legislation creating a
new regulated pool of water to boost the falling level of Lake
Powell unless Colorado adopts a policy that the pool should be
filled only on a voluntary basis. … Water managers from
Southern California to Wyoming are watching the ongoing debate
because if Colorado can’t reach a consensus, an ongoing effort
to establish a “drought contingency planning” program could
Key reservoirs along the Colorado River are collectively at
their lowest point at the start of a new water year since the
last one filled nearly 40 years ago. As of Oct. 1 reservoirs
that store the Colorado River’s water are at just under 47
percent of their capacity, according to recently released
data from the U.S. Bureau of Reclamation.
It was another bad year on the Colorado River, and the numbers
prove it. … “We had a pretty good year in 2017, with an
inflow into Powell of 110 percent of average. But unfortunately
we lost that storage and a little bit more in 2018,” said Dan
Bunk, a U.S. Bureau of Reclamation hydrologist.
After years of stop-and-go talks, California and two other
states that take water from the lower Colorado River are
nearing an agreement on how to share delivery cuts if a formal
shortage is declared on the drought-plagued waterway. Under the
proposed pact, California — the river’s largest user — would
reduce diversions earlier in a shortage than it would if the
lower-basin states strictly adhered to a water-rights pecking
The Colorado River Basin is more
than likely headed to unprecedented shortage in 2020 that could
force supply cuts to some states, but work is “furiously”
underway to reduce the risk and avert a crisis, Bureau of
Reclamation Commissioner Brenda Burman told an audience of
California water industry people.
During a keynote address at the Water Education Foundation’s
Sept. 20 Water Summit in Sacramento, Burman said there is
opportunity for Colorado River Basin states to control their
destiny, but acknowledged that in water, there are no guarantees
that agreement can be reached.
The federal agency that had been handling the permitting
process for the Lake Powell Pipeline announced Thursday it
doesn’t have jurisdiction to handle the entire project on its
own. The Federal Energy Regulatory Commission submitted an
order indicating it would only consider permitting for the
hydroelectric facilities proposed for the project, and not the
remaining 89 miles of connecting water delivery pipelines,
although it would continue as the lead agency in charge of
The intense drought in the Southwest is threatening
Colorado water supplies beyond just the lack of rainfall. State
wildlife officials report a record number of boats carrying
invasive mussels coming into Colorado from out of state. And
the arid summer and winter could be to blame.
Utah has some difficult financial decisions to make as it
considers the Lake Powell Pipeline. The governor-appointed
Executive Water Finance Board toured Washington County water
facilities Tuesday as part of its second and final
day of meetings in Southern Utah. Board members
are considering the pipeline and its potential
costs to both the St. George area and the state as a
Like rust slowly consuming the body of a car, drought has
spread upstream on the Colorado River. The river’s Upper Basin
– generally north of Lake Powell – has been largely insulated
from the 19-year drought afflicting the giant watershed, thanks
to the region’s relatively small water demand and heavy snows
that bury Colorado’s 14,000ft peaks each winter. But this year,
there was no salvation in the snowpack.
Water means life for all the Grand Canyon’s inhabitants, including the many varieties of insects that are a foundation of the ecosystem’s food web. But hydropower operations upstream on the Colorado River at Glen Canyon Dam, in Northern Arizona near the Utah border, disrupt the natural pace of insect reproduction as the river rises and falls, sometimes dramatically. Eggs deposited at the river’s edge are often left high and dry and their loss directly affects available food for endangered fish such as the humpback chub.
With Lake Mead dropping to levels that could trigger water
cutbacks in less than two years, there’s been a lot of
talk lately about negotiating a deal to keep the reservoir from
falling even further. But in a new report, scientists say
the situation is just as worrisome upstream at Lake
Powell. The declines there during the past 18 years, they
say, also reflect the Colorado River’s worsening
Utah wants the federal government to resume its work permitting
the Lake Powell Pipeline. Utah water officials in January
asked to press pause on the project, worried over
jurisdictional questions about whether the Federal Energy
Regulatory Commission (FERC) would continue to act as the
In the past two years, St. George has added nearly 12,000
new residents to a population of approximately 153,000 people,
many of them drawn by the city’s mild climate and access to
public lands. But all this growth has stoked some rising
tension over water and land in this former farm town. …
That’s why in 2006, the Washington County Water Conservancy
District announced plans to pursue a controversial pipeline
connecting Lake Powell to southwest Utah.
Two Western Slope water conservation districts are moving
forward with the third phase of a “risk study” exploring how
much water might be available to bolster water levels in Lake
Powell, and they are doing so without state funding to avoid
Front Range opposition to the study. Lake Powell today is half
full and dropping and water managers say several more years
like 2018 could drain the reservoir, which today contains 12.3
million acre-feet of water.
Amy Haas recently became the first non-engineer and the first woman to serve as executive director of the Upper Colorado River Commission in its 70-year history, putting her smack in the center of a host of daunting challenges facing the Upper Colorado River Basin.
Yet those challenges will be quite familiar to Haas, an attorney who for the past year has served as deputy director and general counsel of the commission. (She replaced longtime Executive Director Don Ostler). She has a long history of working within interstate Colorado River governance, including representing New Mexico as its Upper Colorado River commissioner and playing a central role in the negotiation of the recently signed U.S.-Mexico agreement known as Minute 323.
A conservation ethic is growing in the nation’s second-driest
state. … But Utah’s also pushing forward with a plan to tap
more water from the Colorado River to serve two counties in the
southwestern corner of the state.

the five members of the Upper Colorado River Commission
unanimously passed a resolution to that effect at a board
With rainfall at record lows, water is an increasingly precious
commodity in the deserts of southern Utah. But in the driest
reaches of redrock country, one long-waged water war thunders
even louder than the rest. Utah legislators and water managers
have spent nearly a decade trying to break ground on the
140-mile-long Lake Powell Pipeline, which will carry 77 million
gallons of water annually from the Colorado River to nearby
Washington and Kane Counties.
Reservoirs that store water along the Colorado River are
projected to be less than half full later this year,
potentially marking a historic low mark for the river system
that supplies water to seven U.S. states and Mexico.
Forecasters with the U.S. Bureau of Reclamation expect the
river’s reservoirs — Lakes Mead and Powell among them — to be
at a combined 48 percent of capacity by the end of September.
Nowhere is the domino effect in
Western water policy played out more than on the Colorado River,
and specifically when it involves the Lower Basin states of
California, Nevada and Arizona. We are seeing that play out now
as the three states strive to forge a Drought Contingency Plan.
Yet that plan can’t be finalized until Arizona finds a unifying
voice between its major water players, an effort you can read
more about in the latest in-depth article of Western Water.
Even then, there are some issues to resolve just within
It’s high-stakes time in Arizona. The state that depends on the
Colorado River to help supply its cities and farms — and is
first in line to absorb a shortage — is seeking a unified plan
for water supply management to join its Lower Basin neighbors,
California and Nevada, in a coordinated plan to preserve water
levels in Lake Mead before
they run too low.
If the lake’s elevation falls below 1,075 feet above sea level,
the secretary of the Interior would declare a shortage and
Arizona’s deliveries of Colorado River water would be reduced by
320,000 acre-feet. Arizona says that’s enough to serve about 1
million households in one year.
A bruising battle between the Central Arizona Project and many
states and water users has revitalized the push for a stillborn
plan to prepare for more drought on the Colorado River. The
original dustup was over whether the CAP was seeking to “game
the system” of reservoir operations at lakes Mead and Powell to
benefit itself at the expense of the river’s Upper Basin
states: Utah, Colorado, New Mexico and Wyoming.
Rivers are drying up, popular mountain recreation spots are
closing and water restrictions are in full swing as a
persistent drought intensifies its grip on pockets of the
American Southwest. … With the region’s water resources
strained, a top federal official has resumed pressure on states
in the Southwest to wrap up long-delayed emergency plans for
potential shortages on the Colorado River, which serves 40
million people in the U.S. and Mexico.
The National Oceanic and Atmospheric Administration said the
Colorado River is expected to carry only 43 percent of the
average amount of water into Lake Powell, one of two huge
reservoirs that store and distribute the river. It’s the
fifth-lowest forecast in 54 years.
In early April, federal forecasters came out with a sobering
but not surprising prediction for many Colorado River water
users after a grim snowpack across much of the Colorado River
basin this winter. They projected that as the snow melted and
entered the Colorado River system, much less water would flow
into Lake Powell this spring than is normal.
Central Arizona water managers, facing backlash from other
Colorado River users for allegedly undercutting regional
conservation efforts, will visit Utah later this month
aiming to smooth relations across a region struggling to agree
on a way to save a key water supply.
April is often a time of abundance in the mountains of the
American West, when snowpack is at or near its peak, and
forecasters work to determine how much runoff will course
through our rivers and fill reservoirs later in
the season. This year, across much of the West,
particularly the Southwest, there’s little in the way of
abundance. At Lake Powell, the second-largest reservoir in the
West, runoff is predicted to be only 43 percent of average.
Colorado River forecasters say the Southwest should brace for
the sixth-driest runoff season into Lake Powell since the
government erected Glen Canyon Dam there 55 years ago. …
River flow into Lake Powell is a key measure of water supplies
on the Colorado, a critical water source for millions of people
in seven Western states.
A formidable high-pressure ridge has settled off the West
Coast, deflecting storms northward in much the same pattern
observed in 2013, 2014 and 2015, and though scientists and
policy experts debate the definition of “drought,” few would
disagree that the American West is in the grip of another
extraordinary dry spell.
Lake Powell, which straddles Utah and Arizona, is expected to
get 47 percent of its average inflow because of scant snow in
the mountains that feed the Colorado River, said Greg Smith, a
hydrologist with the Colorado Basin River Forecast Center, part
of the National Oceanic and Atmospheric Administration.

After asking for fast-track review in 2017, officials in Utah
now want federal regulators to delay a decision on whether the
state can build its proposed Lake Powell Pipeline. Construction
of the billion-dollar-plus pipeline to deliver Colorado River
water to communities in southern Utah is already behind
schedule and has cost the state more than $30 million.
Lake Mead ends 2017 at elevation 1,082.5, almost two feet above
last year at this time. Lake Powell ends the year at 3,623, up
more than 20 feet from a year ago. Combined storage in the two
primary Colorado River reservoirs ends the year up more than 2
million acre feet.
