Serving as the “lifeline of the Southwest,” and one of the most
heavily regulated rivers in the world, the Colorado River
provides water to 35 million people and more than 4 million acres
of farmland in a region encompassing some 246,000 square miles.
From its headwaters northwest of Denver in the Rocky Mountains,
the 1,450-mile long river and its tributaries pass through parts
of seven states: Arizona, California, Colorado, New Mexico,
Nevada, Utah and Wyoming and is also used by the
Republic of Mexico. Along the way, almost every drop of the
Colorado River is allocated for use.
The Colorado River Basin is also home to a range of habitats and
ecosystems from mountain to desert to ocean.
Once criticized for being a profligate user of water,
fast-growing Phoenix has taken some major steps — including
banking water in underground reservoirs, slashing per-capita
use, and recycling wastewater — in anticipation of the day when
the flow from the Colorado River ends.
A notice published recently in the Federal Register is not
sitting well with Imperial Irrigation District. That
notice, submitted by the Department of Interior through the
Bureau of Reclamation and published on Feb. 1, calls
recommendations from the governors of the seven Colorado River
Basin state for protective actions the Department of Interior
should take in the absence of a completed drought contingency
A major deadline just passed without unanimous agreement among
Western states over the future of the Colorado River, so the
federal government is one step closer to stepping in on the
dwindling river that provides water for 1-in-8 Americans. The
path forward has become murkier for the drought-stricken region
now in its 19th year of low water levels after a January 31
deadline failed to garner signed agreements from Arizona and
Did the goalposts just move on us? … Media reports suggest
that Reclamation is lumping Arizona with California, which
clearly did not meet the deadline, in its reasoning for taking
an action that we had all hoped to avoid. It’s easy to feel
betrayed by that, to conclude that Arizona was asked to move
mountains and then when we did, we were told it still wasn’t
All eyes were on Arizona this week as state lawmakers took a
last-minute vote on their part of the pact. They approved the
plan Thursday afternoon, just hours before the deadline, but
Arizona officials still haven’t finalized a variety of
documents. In addition, a California irrigation district with
massive river rights has yet to sign off on the
agreement. On Friday, Bureau of Reclamation Commissioner
Brenda Burman … said the agency would start the
formal legal process of soliciting comments on how it should
Communities along the Colorado River are facing a new era of
drought and water shortages that is threatening their future.
With an official water emergency declaration now possible,
farmers, ranchers, and towns are searching for ways to use less
water and survive. Third in a series.
Gov. Doug Ducey signed a drought contingency plan Thursday
afternoon, six hours ahead of the deadline set by a key federal
official for the state to act or face having its Colorado River
water supply determined by her.That came despite objections
from some legislators who questioned why the state will allow
Pinal County farmers to once again pump groundwater for their
crops and will also provide cash to help them do it.
The Bureau of Reclamation, the Interior Department’s Western
water bureaucracy that saw its dam-building heyday in the
1960s, has risen in stature once again in the Trump
administration. Reclamation has flexed its muscles on Colorado
River drought management plans… And it has been the
administration’s key player in trying to fulfill President
Trump’s campaign promise to deliver more water to California
farmers, squeezing the state and forging ahead on a dam project
California says it doesn’t want.
California’s Imperial Irrigation District will get the
last word on the seven-state Colorado River Drought Contingency
Plans. And IID could end up with $200 million to restore the
badly polluted and fast-drying Salton Sea. Thursday, as the
clock ticked toward a midnight deadline set by a top federal
official, all eyes had been on Arizona. But lawmakers there
approved the Colorado River drought deal with about seven hours
to spare. IID, an often-overlooked southeastern California
agricultural water district, appears to have thrown a
last-minute monkey wrench into the process.
The 32-page Layperson’s Guide to the Colorado River covers the
history of the river’s development; negotiations over division
of its water; the items that comprise the Law of the River; and
a chronology of significant Colorado River events.
Arizona lawmakers appear on track to pass a Colorado River
drought plan, with less than 30 hours to go before a critical
federal deadline. A state Senate committee voted 6-1
Wednesday evening to pass a pair of measures that outline
how the state would share looming cutbacks on the
river’s water and work with other states to take less. The
bills now head to the full Senate and House. Both chambers are
expected to pass the bills Thursday, an effort that could
stretch into the night as they rush to meet a federal deadline.
The Colorado River Indian Tribes, or CRIT, have lands that
stretch along 56 miles of the lower Colorado River. The tribe’s
right to divert nearly 720,000 acre-feet from the river is more
than twice the water that is allocated to the state of Nevada.
By law, that water is to be used on the reservation. But if
CRIT convinces Congress to allow off-reservation leasing, the
change would free up a large volume of water that would be
highly desirable for cities and industries.
Warnings of doomsday on the river are nothing new. Too many
people, farms and factories depend on too little water, which
is why the Colorado now rarely flows to its end point at the
Gulf of California. The sprawling Southwest has sucked the
river dry. Yet the region has thrived in spite of the
naysayers. Until now, it appears.
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.
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….
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.
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.
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
Coachella Valley Water District board members on Tuesday
debated issuing a $40 million bond to pay for an extension of
the Oasis pipeline to bring imported water to about 40 farmers
and others in the irrigation district, who would pay the costs
back over 30 years. A small rate increase could be imposed as
well. The 17-mile pipeline and three pump stations would
provide Colorado River water to mostly longtime farmers in the
valley who already obtain much of their water from the river
via the All-American Canal, but get some from wells.
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.
A declining Colorado River in Arizona. Orcas and salmon stocks
in Washington state. Forest restoration in Idaho to protect
drinking water sources from wildfire. And renewable energy
seemingly everywhere. These are some of the water issues that
U.S. governors have mentioned in their 2019 State of the State
speeches. The speeches, usually given at the beginning of the
legislative session, outline budget or policy priorities for
the coming year.
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.
The Metropolitan Water District of Southern California …
began what is being referred to as “defensive withdrawals” from
Lake Mead. Remember, Lake Mead is severely low, and if L.A.
takes all of the water they’ve been allotted, it will trigger
emergency supply restrictions for everyone else. So, why are
they doing this with the agreement deadline so close? The Show
turned to Debra Kahn who covers California environmental policy
and broke the story for Politico Pro.
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.
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.
Everywhere you look new homes, hotels and master-planned
developments are appearing. It is wise to ask whether we
have enough water for these future desert residents and
visitors. Permits for new projects are under the
jurisdiction of cities or the county — not under the purview of
water agencies. Water agencies are tasked with supplying
the water. Balancing growth and water supplies is nothing new
to desert communities. It has always been a fact of life
in our desert and is one of Desert Water Agency’s most
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.
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
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.
In a 5-3 vote Wednesday that — intriguingly — fell along gender
lines, the Phoenix City Council approved an increase in water
rates, starting next month. “I thank the women to have the
leadership and courage to do the right thing. 5-3,”
Interim Mayor Thelda Williams said. … Wednesday’s
vote overturned the council’s previous rejection of
the proposed increase, on December 12, that was also 5-3.
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.”
At Monday’s meeting of the Metropolitan Water District’s
Planning & Stewardship Committee, officials said that with no
Drought Contingency Plan in place (Arizona being the hold out),
they are beginning to draw down their storage in Lake
Mead. “If there is no Drought Contingency Plan, we don’t
want to leave potentially half a million acre-feet or more
locked up in Lake Mead if we go into shortage,”
said General Manager Jeff Kightlinger.
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.
Southern Nevadans will see few noticeable consequences from a
soon-to-be-finalized drought contingency plan for states
that get most of their water supply from the Colorado River,
according to a Southern Nevada water resources expert.

With the water level in Lake Mead hovering near a point that
would trigger a first-ever official shortage on the Colorado
River, representatives of California, Arizona and Nevada are
trying to wrap up a plan to prevent the water situation from
spiraling into a major crisis. The plan is formally called
the Lower Basin Drought Contingency Plan.
The head of the federal agency controlling the Colorado River
said Thursday the U.S. government will impose unprecedented
restrictions on water supplies to the seven Southwestern U.S.
states that depend on the river unless everyone agrees by Jan.
31 on a plan to deal with an expected shortage in 2020.
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.
The Metropolitan Water District of Southern California on
Tuesday approved a plan for sharing Colorado River delivery
cuts if a shortage is declared on the drought-depleted river.
The vote by the district, which imports water to the Southland,
represents another step in a years-long attempt to forge a
shortage agreement among the seven states that depend on the
Colorado for drinking and irrigation supplies.
The Imperial Irrigation District, which holds some of the
oldest and largest rights to Colorado River water, on Monday
tentatively agreed to a one-time contribution of up to 250,000
acre-feet of surplus water if needed to stave off shortages in
Lake Mead. But they tacked on several last-minute conditions
aimed at easing farmers’ fears of permanently losing water, and
to force federal and state officials to guarantee funding for
clean-up of the Salton Sea.
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.
The agency that manages the Central Arizona Project canal
signaled its support for the latest outline of a Colorado River

Arizona says it’s one step closer to figuring out how to divvy
up water cuts as the supply from the Colorado River becomes
more limited. Several Western states that rely on the river are
working on drought plans. The federal government wants them
done by the end of the year.
A state judge on Thursday turned down a powerful Imperial
Valley farmer’s request for an injunction against his
irrigation district to stop them from signing a major Colorado
River conservation plan. Superior Court Judge L. Brooks
Anderholt denied the motion by Michael Abatti and his
attorneys, a court clerk told The Desert Sun.
Arizona’s water agencies, cities, farmers and tribes haven’t
quite sealed a Colorado River deal. But they’re getting
closer. The outline of a new compromise proposal emerged
this week and was presented at a meeting on Thursday.
In a chapter dedicated to climate change effects in the
southwest, climate scientists say “with very high confidence”
that warm temperatures are reducing the water content of
mountain snowpack and the flows of rivers and streams that
depend on snowmelt. The chapter’s landing page features a photo
of low water levels at the nation’s largest reservoir, Lake
Mead outside Las Vegas, Nevada, a near perfect symbol of the
region’s ongoing water challenges.
A group of powerful Imperial Valley farmers and their
irrigation district need to work together for the benefit of
the region, according to Superior Court Judge L. Brooks
Anderholt. He warned a fight between the two sides over rights
to Colorado River water and the need to address a prolonged
drought across the Southwest could spur action by Congress, or
end up in the U.S. Supreme Court.
A fierce local battle over water rights unfolding in a small
Southern California courtroom Wednesday could threaten federal
plans to replenish rapidly dwindling Colorado River water
supplies. A third-generation farmer is seeking an injunction to
block the Imperial Irrigation District from signing on to the
seven-state compact. The hearing comes a day-and-a-half after
the longtime general manager for the district, Kevin Kelley,
announced he will retire at year’s end, though he could stay on
as a consultant.
In the week following a controlled flood on the Colorado
River, Mick Lovett saw lots of fat fish near Lees
Ferry, about 15 miles down river from Glen Canyon Dam. The
fishing was expected to be excellent in that stretch of
the river after the four-day flood stirred up
extra food for the fish, according to the Arizona Game and
Colorado River water managers have plenty to argue about. But
there’s one thing on which nearly everyone who relies on the
southwestern river can agree. The foundational document that
divvies up the water — the Colorado River Compact — has some
big flaws. Discussion on how to fix the compact’s problems is
where that consensus breaks down, often with the invocation of
one word: renegotiation.
The Latest on drought contingency plans being considered by
states that rely on the Colorado River … Las Vegas-area water

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? Increasingly,
tribes are pressing to have the importance of their water
rights recognized and seeking the means to use them. An
impending tribal water study should shed light on the issue as
questions are raised about how to sustainably share water in an
already overallocated Colorado River Basin.
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.
Water managers along the Colorado River are trying to figure
out how to live with less. Climate change is growing the gap
between the river’s supply, and the demands in the communities
that rely on it, including seven western U.S. states and
A public agency and a powerful farmer are gearing up for a
high-stakes court battle to determine who owns the largest
share of Colorado River water in the
West, complicating the river’s future as seven western
states scramble to avoid severe water shortages. There’s a
long history of fighting over water in California’s Imperial
Valley, which has a legal right to more than 1 trillion
gallons of Colorado River water each
year — twice as much as the rest
of California, and as much as Arizona and
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

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
Nearly a decade ago, Gabriel Lozada, a man with a wiry frame
and waves of steel-gray hair who looks exactly like the
mathematician he is, set out to answer what he thought was a
relatively simple question: Could Utah’s proposed Lake Powell
Pipeline — a plan to ferry Colorado River water to southern
Utah — live up to the state’s rosy forecasts of growth and
With a deadline approaching for Arizona to finish a deal that
would divvy up cutbacks in Colorado River water deliveries, the
state’s cities, tribes and agricultural irrigation districts
are entering what should be the final stretch of negotiations.
In the 55 years since the federal government poured more than 5
million cubic yards of concrete across the Colorado River to
form Glen Canyon Dam, the demand for water and electricity in
Arizona, Nevada and California has turned the river’s ecology
upside down. A river once wild, muddy and warm now flows cold
and clear, every drop measured out to supply cities and farms
downstream. Water levels ebb and flow hourly, erasing the
spring surges and summer droughts innate in desert rivers.
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.
Mitt Romney took up the question of water shortage this week in
Utah, one of the driest states in the country, during a debate
as he runs for a U.S. Senate seat in his adopted home state
against Democrat Jenny Wilson. But federal water managers say
he oversimplified a complex issue when he said Utah’s unused
water allotment goes to California.
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
Seven Southwestern U.S. states that depend on the overtaxed
Colorado River have reached landmark agreements on how to
manage the waterway amid an unprecedented drought, including a
commitment by California to bear part of the burden before it
is legally required to do so, officials said Tuesday. The
agreements are tentative and must be approved by multiple
states and agencies as well as the U.S. government.
In 2007, years into a record-breaking drought throughout the
southwestern U.S., officials along the Colorado River finally
came to an agreement on how they’d deal with future water
shortages — and then quietly hoped that wet weather would
return. But it didn’t.
The phrase “climate change” did not appear on the agenda of a
recent three-day meeting of the Colorado Water Congress, but
the topic was often front and center at the conference, as it
increasingly is at water meetings around the state and the
region. Amy Haas, the new executive director of the Upper
Colorado River Commission, told the Water Congress audience of
about 300 water managers, irrigators, engineers and lawyers
that “hydrology is changing more rapidly than we once thought”
and that “it is primarily due to climate change.”
Snowmelt is shrinking and runoff is coming earlier on the Upper
Colorado River, the source of 90 percent of water for 40
million people in the West. This is leading to vegetation
changes, water quality issues and other concerns. But it may be
possible to operate reservoirs differently to ease some of
these effects. In September’s episode of Deeply Talks, we spoke

these changes on the river.
Another rare Colorado River fish has been pulled back from the
brink of extinction, the second comeback this year for a
species unique to the Southwestern U.S. The U.S. Fish and
Wildlife Service plans to announce Thursday that it will
recommend reclassifying the ancient and odd-looking razorback
sucker from endangered to threatened, meaning it is still at
risk of extinction, but the danger is no longer immediate.
The 20-year ban was meant to slow a flurry of mining claims
over concern that the Colorado River — a major water source
serving 30 million people — could become contaminated and to
allow for scientific studies.
Once considered pipe dreams, the concept of saving the Salton

BURMAN ADDRESSES COLORADO RIVER, CALIFORNIA WATER NEEDS IN
SUMMIT TALK; LEARN MORE ABOUT COLORADO RIVER WITH FOUNDATION
The Colorado River is likely headed to unprecedented shortage
in 2020 that could force water 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 at the Foundation’s Sept. 20 Water Summit in
Sacramento. Burman’s talk highlighted the challenges to the
Colorado River Basin from persistent drought, and the efforts
to come to terms on a drought contingency plan to stave off
more draconian supply cuts to those who depend on the river for

In increasingly dry conditions, cities from Australia and the
Middle East to the American Southwest are pursuing groundwater,
either as an integral piece of their future water supply or as
an emergency stopgap measure. Los Angeles, looking long-term,
aims to double the share of its water supply that comes from
groundwater by 2040 and cut reliance on distant and shrinking
sources like the Colorado River.
Monsoon storms in the desert Southwest are vital for recharging
groundwater – but it now appears likely this recharge effect
may be compromised by climate change. The major cities of the
Southwest – Phoenix, Tucson, Albuquerque, Las Vegas – currently
get most of their freshwater from the Colorado River or its
tributaries. That river, however, is experiencing its 19th
straight drought year, suggesting a new permanent dry state is
gripping the giant watershed.

Like rust slowly consuming the body of a car, drought has
spread upstream on the Colorado River. The river’s Upper Basin

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.

cross-border treaty organization.
Warming temperatures are sapping the Colorado River, the water
source for more than 40 million people in the southwest. A new
study finds over the last 100 years the river’s flow has
decreased by more than 15 percent. Colorado State University
researcher Brad Udall co-authored the study with UCLA
scientists Mu Xiao and Dennis Lettenmaier.
The White House plans to nominate Jayne Harkins, head of the

connecting Lake Powell to southwest Utah.
In a story Aug. 15 about the Colorado River, The Associated
Press, relying on information from the U.S. Bureau of
Reclamation, reported erroneously when potential cutbacks could
begin if a shortage is declared. A shortage could be declared
in the latter part of 2019, and cutbacks could begin in 2020,
not late 2019. A corrected version of the story is below:
Despite another dry winter on the Colorado River, Lake Mead and
the millions of people who rely on it will avoid a water
shortage for at least one more year. According to new
projections from the Bureau of Reclamation, there will be just
enough water in the reservoir east of Las Vegas at the end of
2018 to stave off a first-ever federal shortage declaration
that would trigger mandatory cuts in Nevada and Arizona.
A lawsuit in California’s Imperial Valley could

The mention of one plausible future scenario along the Colorado
River is enough to make some water managers in the West break
into a sweat. It’s called the Compact Call, and even though
it’s never happened — and is years away from ever happening —

Water leaders in Arizona are again trying to get to “yes” on a
deal that deals with drought. This would help prepare the state
for future cuts to its water supply if — and likely when –
Lake Mead drops below specific levels. A renewed effort to
achieve an agreement comes after a year of anxiety and gridlock
over the future of the Colorado River.

Despairing over the impending loss of hundreds of jobs and 85
percent of its governmental revenue, the Hopi Tribe recently

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.

In California, awareness of groundwater’s importance resulted in the landmark Sustainable Groundwater Management Act in 2014 that aims to have the most severely depleted basins in a state of balance in about 20 years.
In a pointed message Wednesday, U.S. Bureau of Reclamation
Commissioner Brenda Burman said drought and low flows continue
on the Colorado with no end in sight, so it’s up to those who
rely on the river to stave off a coming crisis.
The U.S. Bureau of Reclamation, which manages the [Colorado]
river, released projections showing a 52 percent chance the
river’s biggest reservoir, Lake Mead in Arizona and Nevada,
will fall low enough in 2020 to trigger cutbacks under
agreements governing the system. … The shortage
projection prompted Bureau of Reclamation Chief Brenda Burman
to prod the seven river states to finish long-delayed
contingency plans for worsening conditions.
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.
Anticipating years of drought, officials built the Yuma

proponents—including scientists, activists, journalists, and
government officials—have cited everything from ecology to

northern Arizona and restore that part of the Colorado River,
very little has been said about the impacts such an action
would have on the house-of-cards-like network of compacts,

A dry winter for the region feeding the Colorado River means
Lake Mead’s water level could drop, but not enough to trigger
an emergency shortage declaration that would force water
cutbacks in Nevada and Arizona.
Near-record low snow levels remained at 60 percent of the
median or less Sunday in the southern half of Colorado in the
Arkansas, Rio Grande, San Miguel, Animas, Dolores and San Juan

half of Colorado, snowpack hovered around 84 percent of the
median in the Upper Colorado River and South Platte River

On our Lower
Colorado River Tour, April 11-13, you will meet with water
managers from the three Lower Basin states: Nevada, Arizona and
California. The three states are working to finalize a Drought
Contingency Plan to take voluntary cuts to keep Lake Mead, the
nation’s largest reservoir, from hitting critical levels and
causing a shortage declaration.
Last year, farmers who lead the irrigation district in Blythe
sued the biggest urban water district in the country to
challenge what they called a “water grab.” Now the Palo Verde
Irrigation District has dropped that lawsuit, looking to smooth
the way toward a possible settlement with the Los Angeles-based
Metropolitan Water District of Southern California.
For years, Colorado River states have been negotiating a plan
to avoid the worst – a shortage in Lake Mead so bad it could
trigger unprecedented cutbacks. With the region experiencing
drought conditions since 2000, even California, which has
senior rights, came to the negotiating table.
An already dry winter for the Colorado River has gotten worse
in recent weeks, but it won’t be enough to send Lake Mead to a
record low — at least not right away. Despite worsening
conditions in the mountains that feed the Colorado, forecasters
still expect the reservoir east of Las Vegas to contain just
enough water by the end of the year to avoid a first-ever
federal shortage declaration.
Arizona will be hardest hit if 17 years of drought keep drying
up a reservoir serving much of the Southwest, but the state’s
lawmakers and governor don’t agree on how to keep water in the
lake or who should be in charge. Lake Mead, a man-made
reservoir fed by the Colorado River, is an essential water
supply for several western states that will take a hit if lake
levels dip much lower.

policy experts debate the definition of “drought,” few would
disagree that the American West is in the grip of another
extraordinary dry spell.
The Colorado and the San Pedro rivers’ futures are on the line
at the Legislature due to a controversial water bill. … But
what’s not in the bill is also stirring conflict, particularly
between the warring Arizona Department of Water Resources and
the Central Arizona Project.
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.
Be prepared for some of the West’s biggest and most important
rivers and streams to see record low flows this spring and

Center’s latest water supply forecast released Monday.
The agency that runs the CAP [Central Arizona Project] is
setting aside Colorado River water for new development that by
all rights should go to the Tohono O’odham and other Indian

Every spring in the western United States, snow melts off
mountains, feeding rivers with surges of water that can cause
disastrous floods. But warm weather isn’t the main culprit, a

For [Celeste] Cantú, who has managed water agencies for more
than two decades, the extraordinary winter heat is also a stark
reminder of how the warming climate is compounding the strains
on water supplies in the West. … The amount of snow
on the ground is also far below average across the Colorado
River Basin, where a 17-year run of mostly dry years has left
reservoirs at alarmingly low levels.
There’s a term for what’s going on right now in the Sierra
Nevada and the mountains that feed the Colorado River. It’s
called a “snow drought,” and Nevada climate scientists warn
that Westerners had better get used to the phenomenon.
Drought conditions persist in Arizona. At the same time, people
in the water policy world are trying to keep the Colorado River
at healthy levels. The Colorado is considered a lifeline for
A controversial pipeline project that would pump Colorado River
water to a rapidly growing corner of Utah passed a regulatory
goal and also hit a regulatory snag on the same day, prompting
the state to ask the federal government to delay further
