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.
The Trump administration is proposing a jaw-dropping $609
million cut to the massive Central Utah Project, which supplies
water to millions of people in northern Utah. … “The Budget
provides $1.2 billion for the Bureau of Reclamation and the
Central Utah Project. The Budget reduces funding for programs
that have nothing to do with building and maintaining water
infrastructure, such as habitat restoration. Instead, the
Budget focuses Reclamation and the Central Utah Project on
their core missions of maintaining assets that provide safe,
reliable, and efficient management of water resources
throughout the western United States,” the reduction item says.
The U.S. Department of Interior said Wednesday it extended more
than a dozen contracts with water-rights holders in California
and Arizona that aim to boost water funding and conservation
efforts in the Colorado River system for its seven western
states. Interior officials say it marked “major progress” with
the Bureau of Reclamation in securing a continuation of 18
short-term agreements with tribal, municipal and agricultural
water users in the lower Colorado River basin that will, they
said, “result in additional water savings” through 2026 and,
likewise, secure its short-term health as the region looks to
its post-2026 water-use guidelines for Lake Powell and Lake
Mead. … Scott Cameron, a senior adviser to U.S. Interior
Secretary Doug Burgum, said the Trump administration
was focused on strengthening the Colorado River system’s
drought response and “safeguarding the interests of western
communities” for more than 40 million citizens and hydropower
fuel resources in its seven states.
Layers of snowpack melted rapidly in Colorado in April, which
could lead to less water supply in the summer and higher
wildfire potential, according to data from the National
Integrated Drought Information System. The federal data,
released on May 1, indicate that “substantial and rapid”
snowmelt occurred throughout broad swaths of Colorado between
April 10-17. Several weather stations maintained by the U.S.
Department of Agriculture logged record snowmelt during that
week, compared to the same period in prior years. … How
quickly snow melts, and when it happens, can impact water
availability during hot summer months and affect how likely
wildfires are to occur in a region. An area that’s seen rapid
snowmelt in early spring could have dried-out vegetation by
summer, a potential fuel for blazes.
Environmental groups are demanding that the Trump
administration exercise the federal government’s authority to
curb wasteful water use in an effort to address the Colorado
River’s chronic water shortages. In a petition submitted
Tuesday, the Natural Resources Defense Council and nine other
groups called for the U.S. Bureau of Reclamation to enforce a
provision of federal regulations stating that water deliveries
in California, Arizona and Nevada “will not exceed those
reasonably required for beneficial use.” … The petition
takes aim in particular at wasteful water practices in
agriculture. … Leaders of the groups that submitted the
petition … suggested in it that the government should also
consider wasteful water use in cities and industries.
This article documents the current status of tribal water
rights
in California and explains why they differ from other
states. … In 1908, the U.S. Supreme Court affirmed in
Winters v. U.S. that through the creation of reservations,
tribes are entitled to water rights sufficient to meet their
homeland needs. … The Klamath Tribes in Oregon, the
Pyramid Lake Paiute Tribe (PLPT) in Nevada, and five
reservations along the California-Arizona border hold
high-priority Winters rights to surface water crossing the
California state line. In each case, the sovereignty tribes
were able to exert over their rights increased when tribal
priorities aligned with state or federal interests.
… Many experts are calling for a collective reframing of
water as a scarce and essential common good.
… Extraction rights and pricing systems that fail to
account for the hidden effects (or ‘externalities’) that come
from using this common good lead to inefficient consumption and
can direct water-intensive activities to regions that are
already water-stressed. … Better pricing through targeted
water-use taxes and subsidies could help to manage demand,
improve access and support more sustainable use. For example,
chip manufacturers like Intel and TSMC have invested in
building semiconductor factories (or ‘fabs’) in Arizona – a
state known for its dry climate. … Better pricing could
have given these companies the incentives to locate their
facilitates in more water-abundant regions, easing pressure on
Arizona’s water system.
… Across Colorado, the snowpack peaked lower in major river
basins than the 30-year median, according to federal data from
1991 to 2020. The peaks were often earlier than usual, and the
snowpack is melting quickly — several weeks earlier than the
norm in some areas. Water managers and climatologists are
hoping for a rainy May and active summer thunderstorm season.
In dry years, farmers and ranchers can be short on irrigation
water in late summer. Reservoirs can have less extra water to
carry over into the next year. Fish and aquatic ecosystems can
suffer with less water in warmer rivers. Water managers across
the desert Southwest are in similar situations. Western
Colorado is a key water source for the Colorado River
Basin, where rivers and streams send water into an
immense reservoir, Lake Powell.
Snowpack was near normal for much of the upper Colorado River
basin this winter. By April 1, which is what hydrologists
typically consider to be the end of winter for water
measurement, the upper basin had received about 90% of its
historical median snowpack. … Despite the overall positive
snowpack report, hydrologists and drought forecasters are not
optimistic about runoff. Forecasters predict that through July,
runoff will be at 67% of average above Lake Powell, the largest
reservoir on the Upper Basin. “Dry soils across the West,
both going into the winter season and during the spring,
combined with a relatively hot, dry March have really
diminished our predicted streamflow for the summer,” said Nels
Bjarke, a hydrologist with the Western Water Assessment.
Housing developers and conservation advocates clashed over a
bill Thursday that would encourage the federal government to
open thousands of acres of public land in Clark County for
development, a move critics say will encourage sprawl and
supporters argue would lower housing costs. … The
resolution’s opponents cited concerns about water scarcity,
utility costs, urban sprawl, and the urban heat island effect.
… A joint study by Clark County and the City of Henderson
found that development under the Clark County Lands Bill could
increase daily water demand by 49 million gallons, or about 18%
of Nevada’s total allocation from the Colorado River.
Rapid melts across the U.S. West have caused snowpack to
disappear up to four weeks early in some areas — wreaking
potential havoc on the region’s water supply, federal
meteorologists warned Thursday. These conditions have
particularly affected parts of Utah, Colorado and New Mexico,
causing some basins to shift from above-average snowpack to
“snow drought,” according to an update from the
National Integrated Drought Information System
(NIDIS). That transition occurred in under a month, with
snow disappearing one to four weeks earlier than usual, the
NIDIS updated stated. … As for the Colorado
River Basin, the NIDIS update said that supply
forecasts for this region declined in comparison to April 1
projections, presumably due to dry conditions and early, rapid
snowmelt.
Interior Department veteran Andrea Travnicek on Wednesday
identified Colorado River policies, critical minerals
development and infrastructure as her top three priorities if
she is confirmed as Interior’s assistant secretary for water
and science. With a background that includes service in the
first Trump administration’s Interior Department and leadership
of North Dakota’s Department of Water Resources, Travnicek
noted that there are “a lot of discussions right now” related
to the 1,450-mile river and the allocation of its water. “We’ve
got some looming deadlines that are in front of us next year,
so we’re going to have to work really closely with those seven
states in the [Colorado River] basin,” Travnicek told the
Senate Energy and Natural Resources Committee.
Across the country, the data collected at stream gauges managed
by the U.S. Geological Survey are used to implement drought
measures when streamflows are low, alert local authorities of
floods, help administer water to users on rivers and issue
pollution discharge permits required by the Clean Water Act for
communities across the country. But more than two dozen USGS
Water Science Centers that house the employees and equipment to
manage those gauges and equipment will soon have their leases
terminated after being targeted by the Department of Government
Efficiency. … The Moab (Utah) office operates and
monitors more than 30 stream gauges, eight water quality sites,
five meteorological sites, two groundwater monitoring sites and
one sediment monitoring site. Many of those … send
information in real time to federal, tribal, state and local
partners about floods and the flows of streams and rivers in
the Colorado River Basin.
Although the top post at the Bureau of Reclamation remains
without a nominee more than 100 days into the second Trump
administration, state officials say the empty seat will not
slow negotiations over a new Colorado River
operating plan. President Donald Trump has yet to put forth a
leader for Reclamation, which is responsible for dams,
reservoirs, canals and other infrastructure across 17 Western
states. David Palumbo, the agency’s deputy commissioner, is
currently serving in an acting capacity. But state
officials said the lack of a Senate-confirmed leader is
unlikely to hamper ongoing talks about how to share the
Colorado River, as well as any potential cuts when flows are
too low to meet the demands of some 40 million people and 5.5
million acres of farmland.
Mexico has agreed to send water to the United States and
temporarily channel more water to the country from their shared
rivers, a concession that appeared to defuse a diplomatic
crisis sparked by yearslong shortages that left Mexico behind
on its treaty-bound contribution of water from the borderlands.
… In a social media post, Mr. Trump accused Mexico of
“stealing” water from Texas farmers by not meeting its
obligations under a 1944 treaty that mediates the distribution
of water from three rivers the two countries share: the
Rio Grande, the Colorado and the Tijuana. In an
agreement announced jointly by Mexico and the United States on
Monday, Mexico will immediately transfer some of its water
reserves and will give the country a larger share of the flow
of water from the Rio Grande through October.
With seven states, 30 tribes and Mexico, the Central Arizona
Project and the Gila River Indian Community addressed the
uncertainty of the Colorado River Basin water
shortage at the 2025 Society of Environmental Journalist
Conference. Facing water shortages in the Colorado River Basin
in the early 200s, the 2007 Colorado River Interim Guidelines
and later the 2019 Drought Contingency Plans were created to
mitigate water use. These plans expire in 2026. New agreements
could potentially lead to less availability of water. “We’re
looking at a new water supply someday. It might not only be
Colorado River water going through the canal system,” said
DeEtte Person, communications strategist for the Central
Arizona Project.
A group* of my Colorado River collaborators
has put together what we hope can be a useful set of
foundational principles as the basin states and federal
leadership search for a path toward a negotiated agreement for
post-2026 Colorado River management. They’re based on a number
of key premises: The Colorado River Compact will remain the
foundation of the river’s management, but we have to find a way
past the deep disagreement between Upper and Lower basin states
on what the Compact actually says.
As the deadline to renegotiate Colorado River
water use agreements approaches, Democratic
Senator John Hickenlooper says he is “frustrated”
with the lack of progress on a consensus between the seven
basin states. … New guidelines are needed by 2026 to
replace the current set of rules. Federal officials previously
released five conceptual alternatives, including a “no action”
option required under environmental law, to determine how to
allocate dwindling water resources. One proposal emphasizes
infrastructure protection and strict limits on water deliveries
during shortages, while another promotes expanded conservation
and flexible storage solutions.
… Water users across the (Colorado River Basin) have for
years been talking about what to do next. They agree that water
use should be cut deeper and for the longer haul than we have
before. There are even proposals to do so. But no one knows
which — if any — are still on the table. … It’s telling that
while state negotiators continue to meet (and make no real
progress), no one from the Bureau of Reclamation — the federal
agency tasked with operating Lake Mead and Lake Powell — has
attended those negotiation sessions since the Trump
administration took office. In fact, Reclamation still doesn’t
even have a commissioner. The administration has been dragging
its feet on getting the leadership in place to finally break
this logjam. And time is running short. –Written by Arizona Republic columnist Joanna
Allhands.
During a tour of the Western Slope last week, U.S. Sen.
John Hickenlooper, D-Colo., said he was frustrated with the
pace of negotiations that could determine how the
Colorado River is shared in the future and
that the Upper Basin states may be pushing back too hard. A
deal should have been reached last summer, he said. “Colorado
should have a right to keep the water that we have been using
the way we’ve been using it, and I don’t think we should
compromise that,” Hickenlooper said. … The seven states that
use water from the Colorado River – Arizona, California and
Nevada comprise the Lower Basin – have just over a month left
to agree on how the nation’s two largest reservoirs would be
operated and cuts shared in the future before the federal
government may decide for them.
Humans have the technology to literally make snow fall from the
clouds. In the drought-stricken Southwest, where the
Colorado River needs every drop of water it
can get, there are calls to use it more. Utah, home to the
nation’s largest cloud seeding program, is at the crossroads of
the technology’s past and future. The state has become a
proving ground for cloud seeding in the West, with water
managers, private sector investors, and conspiracy theorists
keeping a close eye on their progress. … Utah’s
cloud seeding program is being closely watched by others around
the region. Its efforts cover more ground than any other state
in the nation, and it has one of the strongest bases of state
funding. For that reason, other water-short states in the
Western U.S. are keeping an eye on how much return on
investment Utah is getting from a $5 million annual cloud
seeding budget and those efficiency-boosting tech upgrades.
With drought conditions worsening in southern Utah, Gov.
Spencer Cox says he’s working on issuing an emergency
declaration. Despite northern Utah seeing average snow
this year, counties in the south are exceptionally dry. Cox
said he’s currently working with local officials on the
declaration, which could extend to a handful of counties in the
southwestern corner of Utah that have seen a meager snowpack
this winter. … Statewide, the snow water equivalent —
which is basically the amount of water currently in the
snowpack — is at about 78% of normal, according to the Natural
Resources Conservation Service, or NRCS, which tracks the
snowpack at sites around the state. Much of northern Utah is
between that or higher, with Snowbird’s site at 96%, and a site
in Big Cottonwood Canyon at 115%.
… Today, more than 27 million people in the three states rely
on water from the Colorado River—roughly two-thirds of the
total population that the river serves. Yet even as that
dependence on the river grew, a collision between human and
environmental needs was brewing. … For municipal and
agricultural water managers who depended on the Colorado, the
growing list of endangered species was a wakeup call. It
spurred a decade-long effort to craft a multi-party agreement
that allowed water agencies to continue delivering water to
their users while staying ahead of the mounting endangered
species issues. That effort has largely proven successful, but
as the program now crosses the 20-year mark, new questions are
arising about how to keep it strong for the next three decades
in the face of grinding drought, contentious negotiations over
the river’s future, and new uncertainties about the federal
government’s role in its continued implementation.
Before the construction of Hoover Dam on the lower Colorado River, as well as a slew of smaller sisters downstream, the stretch downriver served as a biological oasis in the middle of the unrelenting Mojave and Sonoran deserts. The marshes and backwaters along the river’s edge provided sheltered areas for fish to spawn and rear their young, and mesquite and cottonwood-willow forests provided important habitat for numerous species of birds and other animals.
Democratic Gov. Katie Hobbs vetoed a swath of bills on water
issues this week, calling them “political cover” for what she
says is the Legislature’s inaction on water security. Hobbs
vetoed seven bills in total, all sponsored by Rep. Gail Griffin
(R-Hereford), who has a history of blocking Hobbs’ and
Democrats’ policy proposals. The bills would have made multiple
policy changes, like modifying definitions of terms and giving
voters an option for removing groundwater protections in parts
of the state under Active Management Areas. Hobbs wrote in a
veto letter that all the bills Griffin sent her either weaken
water protections or make “pointless trivial statutory changes”
that Hobbs argued demean Arizonans who want real groundwater
management.
If any of the Colorado River management options were used to
manage this year’s sub-par snowpack, Arizona, California and
Nevada would be forced to slash 17% to 43% of their legal
share. Coloradans would be focused on voluntary conservation.
Colorado River officials are debating six options for how to
manage the overstressed river after 2026 with the goal of
reaching a seven-state agreement by May. Under this year’s
water conditions, all of the proposed plans would call for
mandatory cuts in the three Lower Basin states with reductions
ranging from 1.3 million to 3.2 million acre-feet. The basin’s
legal share of the river is 7.5 million acre-feet, although
estimates say its actual use is higher. Under most of the
different management options, Colorado and its sister states in
the Upper Basin would be asked to voluntarily conserve up to
500,000 acre-feet of water.
Along the U.S.–Mexico border in Arizona, the Cocopah Indian
Tribe is accustomed to change. Over centuries, they have seen
borders drawn that intersect their homeland. They’ve watched
their traditional way of life adapt and survive with each new
generation. The Cocopah are known as “the river people,” a name
given long before the Colorado River was diverted through
modern canals and dams. As the water disappeared, so did sacred
animals that dwelled in the riverside habitat. … To reconnect
to this cultural power source, the Cocopah have partnered with
the National Audubon Society on two significant restoration
projects on the reservation’s North and West sections. Federal
grant funding is helping the Tribe transform more than 400
acres in the Colorado River floodplain.
Mexico’s President Claudia Sheinbaum on Tuesday denied reports
that Mexico had capitulated to U.S. demands for immediate water
deliveries required by a 1944 treaty that allocates surface
water along their shared border. One of the reports, published
by the Mexican newspaper Reforma, stated that the Coahuila dam
“La Amistad” had increased its extractions by
600%. Calling the published reports “false,” Sheinbaum
said her administration is negotiating with northern states to
send more water to the U.S. while recognizing that pervasive
drought conditions have made it impossible to keep up with
deliveries. “Talks are underway with the governors of
Tamaulipas, Coahuila and Chihuahua to reach a joint agreement
to determine how much water can be delivered … without
affecting Mexican producers, while also complying with the 1944
treaty,” Sheinbaum said at her daily press conference.
Last month, the Wyoming Game and Fish Department (WGFD)
celebrated a rebound of native fish in the Big Sandy water
basin after 20 years of planning and treatment. The project
aimed to restore populations of flannelmouth suckers and
bluehead suckers, which are listed as species of greatest
conservation need in Wyoming and the Colorado River Basin. …
When the dams were built in the 1950s, they trapped some of the
large river species that were upstream from returning to the
Colorado River. As most Colorado River
tributaries were dammed, these species struggled to reproduce,
which resulted in declining populations throughout the mountain
states. … This project focused on removing illegally
introduced burbot, which were eating the smaller native
suckers, and invasive suckers, which were hybridizing with the
native suckers.
Every year, when snow from the Rocky Mountains melts into
water, it finds its way into Lake Powell, the country’s
second-biggest reservoir. But with each passing season, less
snowmelt becomes reservoir water that 40 million people can use
to drink, plant crops or satiate their
lawns. … Atmospheric demand from climate change is
one piece of the puzzle, as Schumacher puts it, as to why
federal projections show that runoff into Lake Powell will
reach about 67 percent of a historic average this season. Other
reasons include dry soils and hotter temperatures accelerating
sublimation, the process where solid snow turns only into gas
instead of liquid, Schumacher said. Snowpack itself above the
reservoir has hovered between around 84 and 91 percent of
average in this month’s readings — another poor showing that
continues over two decades of Western drought.
Hours after President Donald Trump threatened Mexico with
additional tariffs over a massive water debt, that country’s
president publicly vowed to make a substantial payment soon.
Under a 1944 treaty, Mexico must send 1.75 million acre-feet of
water to the U.S. from the Rio Grande every five years, and the
United States is to pay Mexico 1.5 million acre-feet of water
annually via the Colorado River out West. The
current five-year cycle ends in October and Mexico, so far, has
paid only 512,604 acre-feet of water to the United States —
about one-third of what it owes — according to the latest IBWC
data published Friday. … On Friday morning, Mexican President
Claudia Sheinbaum Pardo said her country doesn’t have enough
water to give to the United States but will make payments.
U.S. President Donald Trump on Thursday threatened Mexico with
sanctions and tariffs in a dispute over water sharing between
the two countries, accusing Mexico of breaking an 81-year-old
treaty and “stealing the water from Texas Farmers.” Under the
1944 treaty, Mexico must send 1.75 million acre-feet of water
to the U.S. from the Rio Grande through a network of
interconnected dams and reservoirs every five years.
… The treaty also requires that the U.S. deliver 1.5
million acre-feet of water annually to Mexico from the
Colorado River, an obligation that the U.S.
has largely fulfilled, although recent deliveries have been
reduced due to severe drought, something the 1944 accord allows
for. While Mexico sends far less water to the U.S., it has
struggled to fulfill its end of the bargain due to a
combination of factors including droughts, poor infrastructure
and growing local demand.
The Arizona Department of Water Resources (ADWR) has been
tasked with developing a model which will enable staff to
determine just how much water is in all the nooks and crannies
of the Willcox basin and others around the state. Rep. Gail
Griffin (R–LD14) tasked the agency, which oversees water issues
within the various basins in the state, to prepare a report so
legislators can make more informed decisions before making
rural groundwater policies, she stated. “Are groundwater levels
decreasing in certain basins? Yes, but the first step should be
to stop the bleeding to prevent the rate of decline from
getting worse. Then we can develop tools to help stabilize the
aquifer and find ways to put more water back in the basin, such
as groundwater recharge, reuse and new technology for farming,”
she stated.
The United States is holding back water payments to Mexico in
order to send a message, the U.S. International Boundary and
Water Commissioner told Border Report. “The first action
that the State Department has done is in denying water
deliveries to Mexico in the Tijuana area,” U.S. IBWC
Commissioner Maria-Elena Giner told Border Report last
week. Under a 1944 international treaty, Mexico is
supposed to send 1.75 million acre-feet of water to the United
States via the Rio Grande over five-year
cycles. … The United States, likewise, under the
treaty is required to send to Mexico 1.5 million acre-feet of
water from the Colorado River. But Giner says requested
deliveries to Tijuana, Mexico, south of San Diego, were not
recently fulfilled. And she says more holding back of water,
and other resources, could come next if Mexico fails to send
the U.S. water.
Water and environmental groups in southwestern Colorado have
not heard a peep from the federal government since their $25.6
million grant got caught up in a widespread funding freeze,
officials say. Southwestern Water Conservation District pulled
together a unique collection of partners in 2024 to tap into an
immense stack of federal cash for environmental projects in the
Colorado River Basin. The partners were “ecstatic” Jan. 17 when
they found out their application to fund 17 projects was
accepted, Steve Wolff, district manager, said. Three days
later, President Donald Trump paused spending, and the
district’s partnership has been in limbo ever since. Other
Colorado groups are in the same boat with millions of dollars
of awarded grant funding on the line. … The uncertainty
has impacted a slew of environmental projects across the Upper
Colorado River Basin — Colorado, New Mexico, Utah and Wyoming.
Utah lawmakers have given the state more voice in negotiations
over the Colorado and Bear rivers. The move, however, has some
environmentalists concerned about the sensitive multi-state
agreements that govern the rivers. Utah water agent Joel
Ferry’s job is to help secure his state’s future water needs.
Ferry, whose position was created during the 2024 legislative
session, said he’s looking at everything from conservation to
new sources. Previous legislation prevented him from
negotiating with other states tied to interstate water
compacts. Now, a new Utah law gives Ferry the power to
collaborate on water issues with states in the Colorado and
Bear river basins. But Kyle Roerink, executive director of the
Great Basin Water Network, a water policy nonprofit, is
concerned Ferry could be a wild card in sensitive talks over
the rivers’ futures.
California isn’t recycling nearly enough water, according to a
new report by UCLA researchers, who say the state should treat
and reuse more wastewater to help address the Colorado River’s
chronic shortages. Analyzing data for large sewage treatment
plants in seven states that rely on Colorado River water, the
researchers found California is recycling only 22% of its
treated wastewater. That’s far behind the country’s driest two
states: Nevada, which is recycling 85% of its wastewater, and
Arizona, which is reusing 52%. The report, based on 2022 data,
found other states in the Colorado River Basin are trailing,
with New Mexico recycling 18%, Colorado 3.6%, Wyoming 3.3% and
Utah less than 1%.
As the possibility of legal battles on the Colorado River
grows, competing states could use water data to back up their
arguments, including claims that Arizona should bear the most
water cuts in future shortages The Upper Colorado River
Commission — a body that represents the four states in the
upper Colorado River basin — is in its third year beefing up
the measurement of stream flows, water consumption by
crops, and water diversions that its states use to regulate
their water use. Though the Trump administration is reviewing
the federal funding designated for the projects, the commission
says it has continued its work. … The new data will help
the Upper Basin fine-tune its water management, but it could
also play a role in lawsuits between Colorado River states if
ongoing negotiations break down.
… The Colorado River in the United States is one of the main
arenas in the global water crisis. In the summer of 2022, Lake
Mead, formed by the Hoover Dam, was holding just a quarter of
its potential water capacity. The Colorado River arises in the
Rocky Mountains and supplies water to seven US states.
California is the largest consumer. Cities with millions of
inhabitants, such as Los Angeles and San Diego, depend on its
water but most of it flows into this agricultural zone in the
middle of the desert. The All American Canal carries 80% of
California’s share of Colorado water to the Imperial Valley
along the Mexican border. Until the early 20th century, the
Imperial Valley was an uninhabited desert. Now it’s one of the
key cultivation zones in the US, all thanks to the waters of
the Colorado River. The most important crop is clover, or more
precisely alfalfa, animal feed.
Colorado River states have weeks remaining to resolve deep
divides over how to manage the river for years to come,
officials at a water conference in southwestern Colorado said
Friday. … Basin officials must submit a joint management
proposal by May for it to be considered in the larger federal
process that will decide how the river is managed. A
seven-state agreement would send a clear signal to federal
decision-makers about how the basin wants to manage its own
water future. But for months, basin state officials at the
center of negotiations have been at odds. … The current
river management agreement lapses fully in September 2026, and
there are many steps left in a larger federal process before a
new management plan is finalized.
A new aquatic invader, the golden mussel, has penetrated California’s ecologically fragile Sacramento-San Joaquin Delta, the West Coast’s largest tidal estuary and the hub of the state’s vast water export system. While state officials say they’re working to keep this latest invasive species in check, they concede it may be a nearly impossible task: The golden mussel is in the Golden State to stay – and it is likely to spread.
The 2024 Colorado River Water
Leaders cohort completed its seven-month program
with policy recommendations involving ”augmentation” –
projects that increase the availability and supply of water – as
the Colorado River Basin grows hotter and drier.
The cohort of
12 up-and-coming leaders included engineers,
lawyers, resource specialists and others working for public,
private and non-governmental organizations from across the
river’s basin. The cohort had full editorial control to choose
its recommendations.
State water management officials must work more closely with
local agencies to properly prepare California for the effects
of climate change, water scientists say. Golden State
officials said in the newly revised California Water
Plan that as the nation’s most populous state, California
is too diverse and complex for a singular approach to manage a
vast water network. On Monday, they recommended expanding the
work to better manage the state’s precious water resources —
including building better partnerships with communities most at
risk during extreme drought and floods and improving critical
infrastructure for water storage, treatment and distribution
among different regions and watersheds.
Six tribes in the Upper Colorado River Basin, including two in
Colorado, have gained long-awaited access to discussions about
the basin’s water issues — talks that were formerly
limited to states and the federal government. Under an
agreement finalized this month, the tribes will meet every two
months to discuss Colorado River issues with an interstate
water policy commission, the Upper Colorado River Commission,
or UCRC. It’s the first time in the commission’s 76-year
history that tribes have been formally included, and the timing
is key as negotiations about the river’s future intensify.
… Most immediately, the commission wants a key number:
How much water goes unused by tribes and flows down to the
Lower Basin?
Sustaining the American Southwest is the Colorado River. But
demand, damming, diversion, and drought are draining this vital
water resource at alarming rates. The future of water in the
region – particularly from the Colorado River – was top of mind
at the 10th Annual Eccles Family Rural West Conference, an
event organized by the Bill Lane Center for the American West
that brings together policymakers, practitioners, and scholars
to discuss solutions to urgent problems facing rural Western
regions.
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

The Layperson’s Guide to the Colorado River Basin introduces the
1,450-mile river that sustains 40 million people and millions of
acres of farmland spanning seven states and parts of northern
Mexico.
The 28-page primer explains how the river’s water is shared and
managed as the Southwest transitions to a hotter and drier
climate.
A much-anticipated water bill brought by one of the most
powerful lawmakers on Capitol Hill became public Thursday.
Senate President Stuart Adams’s SB 211, titled “Generational
Water Infrastructure Amendments,” seeks to secure a water
supply for decades to come. It forms a new council comprised of
leadership from the state’s biggest water districts that will
figure out Utah’s water needs for the next 50 to 75 years. It
also creates a new governor-appointed “Utah Water Agent” with a
$1 million annual budget that will “coordinate with the council
to ensure Utah’s generational water needs are met,” according
to a news release. But combing through the text of the bill
reveals the water agent’s main job will be finding an
out-of-state water supply. … The bill also notes the
water agent won’t meddle with existing water compacts with
other states on the Bear and Colorado rivers.
Moab is a growing town of 5,300 that up to 5 million people
visit each year to hike nearby Arches and Canyonlands national
parks, ride mountain bikes and all-terrain vehicles, or raft
the Colorado River. Like any western resort town, it
desperately needs affordable housing. What locals say it
doesn’t need is a high-end development on a sandbar projecting
into the Colorado River, where groves of cottonwoods, willows
and hackberries flourish. “Delusional,” shameful” or
“outrageous” is what many locals call this Kane Creek
Preservation and Development project. - Written by Mary Moran, a contributor to Writers on
the Range
The attention is on Southern California right now, but an
atmospheric river’s path will extend inland with potential
flooding — and possible drought relief. If you’re watching the
weather, it’s still a little early to tell whether these storms
will go where they can hope Las Vegas the most. That’s anywhere
in the Upper Colorado River Basin, where there’s a chance they
could produce snow to help the river that supplies 90% of the
water used in Southern Nevada. … The paths of this
year’s atmospheric rivers are unlike the ones that slammed
the Sierras last year. Those storms carried snow straight
east through Northern Nevada and Utah, feeding the Rocky
Mountains with snowpack levels that reached 160% of normal by
the end of winter.
Water regulation in Arizona has devolved into a game of
chicken. The governor and farmers are rivals revving their
engines, hoping their opponent will flinch first. Caught
in the middle is Gila Bend, a groundwater basin south of
Buckeye, where the state could decide to impose its most
stringent form of regulation, whether folks like it or not.
Both sides are using Gila Bend as a bargaining chip to win
support for competing legislative proposals. But to what
end? - Written by Joanna Allhands, Arizona Republic digital
opinions editor
Colorado legislators in 2022 passed a bill that delivered $2
million to programs across the state for removal of turf in
urban areas classified as nonfunctional. By that, legislators
mean Kentucky bluegrass and other thirsty-grass species that
were meant to be seen but rarely, if ever, otherwise
used. Now, they are taking the next step. The Colorado
Senate on Tuesday, Jan. 30 voted in favor of a
bill, Senate Bill 24-005, that would prevent thirsty turf
species from being planted in certain places that rarely, if
ever, get foot traffic, except perhaps to be mowed.
The U.S. Senate Indian Affairs Committee is holding an
important hearing Thursday on S. 2385, a bill to
refine the tools needed to help Tribal communities gain access
to something that most non-Indian communities in the western
United States have long taken for granted: federally subsidized
systems to deliver safe, clean drinking water to our homes.
… This is the sort of bill (there’s a companion on the
House side) that makes a huge amount of sense, but could easily
get sidetracked in the chaos of Congress. The ideal path is for
the crucial vetting to happen in a process such as Thursday’s
hearing, and then to attach it to one of those omnibus things
that Congress uses these days to get non-controversial stuff
done. Clean water for Native communities should pretty clearly
be non-controversial.
For as long as he can remember, Rob Sowby has heard people call
Utah the second-driest state in the nation. Over the years,
that claim has become nearly inescapable, echoed by everyone
from state departments, city governments and water conservancy
districts to national news outlets without a clear citation for
what data it’s based on. … Now a Brigham Young
University civil engineering assistant professor focused on
sustainable water supplies, he decided to get to the bottom of
it. Using precipitation data, he found that Utah is actually
the nation’s third-driest state, behind Nevada and
Arizona.
The Topock Marsh has seen a significant drop in water levels
recently, with dry patches visible and locals concerned about
the effects on wildlife. The 4,000-acre Bureau of Reclamation
marsh is adjacent to the Colorado River in the Havasu National
Wildlife Refuge. Managed by the U.S. Fish and Wildlife Service,
it serves as a recreation area and wildlife habitat for the
Tri-state.

After more than two decades of
drought, water utilities serving the largest urban regions in the
arid Southwest are embracing a drought-proof source of drinking
water long considered a supply of last resort: purified sewage.
Water supplies have tightened to the point that Phoenix and the
water supplier for 19 million Southern California residents are
racing to adopt an expensive technology called “direct potable
reuse” or “advanced purification” to reduce their reliance on
imported water from the dwindling Colorado River.
Join a
virtual Q&A session Dec. 7 to learn more about
applying for our 2024 Colorado River Water
Leaders cohort.
The biennial
program, which will run from March to September next
year, selects about a dozen rising stars from the
seven states that rely on the river – California, Nevada,
Arizona, Colorado, Wyoming, Utah and New Mexico.
The climate-driven shrinking of the
Colorado River is expanding the influence of Native American
tribes over how the river’s flows are divided among cities, farms
and reservations across the Southwest.
The tribes are seeing the value of their largely unused river
water entitlements rise as the Colorado dwindles, and they are
gaining seats they’ve never had at the water bargaining table as
government agencies try to redress a legacy of exclusion.
The application window is now open
for our Colorado River Water
Leaders program, which will run from March to
September next year.

The states of the Lower Colorado
River Basin have traditionally played an oversized role in
tapping the lifeline that supplies 40 million people in the West.
California, Nevada and Arizona were quicker to build major canals
and dams and negotiated a landmark deal that requires the Upper
Basin to send predictable flows through the Grand Canyon, even
during dry years.
But with the federal government threatening unprecedented water
cuts amid decades of drought and declining reservoirs, the Upper
Basin states of Wyoming, Utah, Colorado and New Mexico are
muscling up to protect their shares of an overallocated river
whose average flows in the Upper Basin have already dropped
20 percent over the last century.
They have formed new agencies to better monitor their interests,
moved influential Colorado River veterans into top negotiating
posts and improved their relationships with Native American
tribes that also hold substantial claims to the river.
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

This special Foundation water tour journeyed along the Eastern Sierra from the Truckee River to Mono Lake, through the Owens Valley and into the Mojave Desert to explore a major source of water for Southern California, this year’s snowpack and challenges for towns, farms and the environment.
When the Colorado River Compact was
signed 100 years ago, the negotiators for seven Western states
bet that the river they were dividing would have ample water to
meet everyone’s needs – even those not seated around the table.
A century later, it’s clear the water they bet on is not there.
More than two decades of drought, lake evaporation and overuse of
water have nearly drained the river’s two anchor reservoirs, Lake
Powell on the Arizona-Utah border and Lake Mead near Las Vegas.
Climate change is rendering the basin drier, shrinking spring
runoff that’s vital for river flows, farms, tribes and cities
across the basin – and essential for refilling reservoirs.
The states that endorsed the Colorado River Compact in 1922 – and
the tribes and nation of Mexico that were excluded from the table
– are now straining to find, and perhaps more importantly accept,
solutions on a river that may offer just half of the water that
the Compact assumed would be available. And not only are
solutions not coming easily, the relationships essential for
compromise are getting more frayed.
With 25 years of experience working
on the Colorado River, Chuck Cullom is used to responding to
myriad challenges that arise on the vital lifeline that seven
states, more than two dozen tribes and the country of Mexico
depend on for water. But this summer problems on the
drought-stressed river are piling up at a dizzying pace:
Reservoirs plummeting to record low levels, whether Hoover Dam
and Glen Canyon Dam can continue to release water and produce
hydropower, unprecedented water cuts and predatory smallmouth
bass threatening native fish species in the Grand Canyon.
“Holy buckets, Batman!,” said Cullom, executive director of the
Upper Colorado River Commission. “I mean, it’s just on and on and
on.”
As water interests in the Colorado
River Basin prepare to negotiate a new set of operating
guidelines for the drought-stressed river, Amelia Flores wants
her Colorado River Indian Tribes (CRIT) to be involved in the
discussion. And she wants CRIT seated at the negotiating table
with something invaluable to offer on a river facing steep cuts
in use: its surplus water.
CRIT, whose reservation lands in California and Arizona are
bisected by the Colorado River, has some of the most senior water
rights on the river. But a federal law enacted in the late 1700s,
decades before any southwestern state was established, prevents
most tribes from sending any of its water off its reservation.
The restrictions mean CRIT, which holds the rights to nearly a
quarter of the entire state of Arizona’s yearly allotment of
river water, is missing out on financial gain and the chance to
help its river partners.
Momentum is building for a unique
interstate deal that aims to transform wastewater from Southern
California homes and business into relief for the stressed
Colorado River. The collaborative effort to add resiliency to a
river suffering from overuse, drought and climate change is being
shaped across state lines by some of the West’s largest water
agencies.

program in 2022, which marks the 100th anniversary
of the Colorado River Compact.
The biennial program is modeled after our highly successful
Water Leaders

Our Colorado River program will select rising stars from the
seven U.S. states and tribal nations that rely on the river -
California, Nevada, Arizona, Colorado, Wyoming, Utah and New
Mexico – to participate in the seven-month class designed for
working professionals. Class members will explore issues
surrounding the iconic Southwest river, deepen their water
knowledge and build leadership skills.
Climate scientist Brad Udall calls
himself the skunk in the room when it comes to the Colorado
River. Armed with a deck of PowerPoint slides and charts that
highlight the Colorado River’s worsening math, the Colorado State
University scientist offers a grim assessment of the river’s
future: Runoff from the river’s headwaters is declining, less
water is flowing into Lake Powell – the key reservoir near the
Arizona-Utah border – and at the same time, more water is being
released from the reservoir than it can sustainably provide.

For more than 20 years, Tanya
Trujillo has been immersed in the many challenges of the Colorado
River, the drought-stressed lifeline for 40 million people from
Denver to Los Angeles and the source of irrigation water for more
than 5 million acres of winter lettuce, supermarket melons and
other crops.
Trujillo has experience working in both the Upper and Lower
Basins of the Colorado River, basins that split the river’s water
evenly but are sometimes at odds with each other. She was a
lawyer for the state of New Mexico, one of four states in the
Upper Colorado River Basin, when key operating guidelines for
sharing shortages on the river were negotiated in 2007. She later
worked as executive director for the Colorado River Board of
California, exposing her to the different perspectives and
challenges facing California and the other states in the river’s
Lower Basin.
Known for our popular Water Leaders
program in California – about to mark its 25th anniversary – we
are now launching a Colorado
River Water Leaders program in 2022, the 100th
anniversary of the Colorado River Compact.
The biennial program will select rising stars from the seven
U.S. states that rely on the river – California, Nevada, Arizona,
Colorado, Wyoming, Utah and New Mexico – to participate in the
seven-month class designed for working professionals. Class
members will explore issues surrounding the iconic Southwest
river, deepen their water knowledge and build leadership
skills.
Water is flowing once again
to the Colorado River’s delta in Mexico, a vast region that
was once a natural splendor before the iconic Western river was
dammed and diverted at the turn of the last century, essentially
turning the delta into a desert.
In 2012, the idea emerged that water could be intentionally sent
down the river to inundate the delta floodplain and regenerate
native cottonwood and willow trees, even in an overallocated
river system. Ultimately, dedicated flows of river water were
brokered under cooperative
efforts by the U.S. and Mexican governments.
Las Vegas, known for its searing summertime heat and glitzy casino fountains, is projected to get even hotter in the coming years as climate change intensifies. As temperatures rise, possibly as much as 10 degrees by end of the century, according to some models, water demand for the desert community is expected to spike. That is not good news in a fast-growing region that depends largely on a limited supply of water from an already drought-stressed Colorado River.
When you oversee the largest
supplier of treated water in the United States, you tend to think
big.
Jeff Kightlinger, general manager of the Metropolitan Water
District of Southern California for the last 15 years, has
focused on diversifying his agency’s water supply and building
security through investment. That means looking beyond MWD’s
borders to ensure the reliable delivery of water to two-thirds of
California’s population.
Twenty years ago, the Colorado River
Basin’s hydrology began tumbling into a historically bad stretch.
The weather turned persistently dry. Water levels in the system’s
anchor reservoirs of Lake Powell and Lake Mead plummeted. A river
system relied upon by nearly 40 million people, farms and
ecosystems across the West was in trouble. And there was no guide
on how to respond.
Managing water resources in the Colorado River Basin is not for the timid or those unaccustomed to big challenges. Careers are devoted to responding to all the demands put upon the river: water supply, hydropower, recreation and environmental protection.
All of this while the Basin endures a seemingly endless drought and forecasts of increasing dryness in the future.
Practically every drop of water that flows through the meadows, canyons and plains of the Colorado River Basin has reams of science attached to it. Snowpack, streamflow and tree ring data all influence the crucial decisions that guide water management of the iconic Western river every day.
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.
The Colorado River Compact of 1922
marked the first time in U.S. history that more than three states
negotiated an agreement among themselves to apportion the waters
of a stream or river.
The compact is the cornerstone of the “Law of the River” – a
complex set of interstate compacts, federal laws, court decisions
and decrees, contracts and federal actions that regulate use of
the Colorado River.
Out of sight and out of mind to most
people, the Salton Sea in California’s far southeast corner has
challenged policymakers and local agencies alike to save the
desert lake from becoming a fetid, hyper-saline water body
inhospitable to wildlife and surrounded by clouds of choking
dust.
The sea’s problems stretch beyond its boundaries in Imperial and
Riverside counties and threaten to undermine multistate
management of the Colorado River. A 2019 Drought Contingency Plan for the
Lower Colorado River Basin was briefly stalled when the Imperial
Irrigation District, holding the river’s largest water
allocation, balked at participating in the plan because, the
district said, it ignored the problems of the Salton Sea.
Colorado is home to the headwaters
of the Colorado River and the water policy decisions made in the
Centennial State reverberate throughout the river’s sprawling
basin that stretches south to Mexico. The stakes are huge in a
basin that serves 40 million people, and responding to the water
needs of the economy, productive agriculture, a robust
recreational industry and environmental protection takes
expertise, leadership and a steady hand.
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.
This event explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.

Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed
them.
The Colorado River is arguably one
of the hardest working rivers on the planet, supplying water to
40 million people and a large agricultural economy in the West.
But it’s under duress from two decades of drought and decisions
made about its management will have exceptional ramifications for
the future, especially as impacts from climate change are felt.
Every other year we hold an
invitation-only Colorado River Symposium attended by various
stakeholders from across the seven Western states and Mexico that
rely on the iconic river. We host this three-day event in Santa
Fe, N.M., where the 1922 Colorado River Compact was signed, as
part of our mission to catalyze critical conversations to build
bridges and inform collaborative decision-making.
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. They argue that stakeholders who are
preparing to rewrite the operating rules of the river should plan
now for how to handle these so-called “black swan” events so
they’re not blindsided.
Dates are now set for two key
Foundation events to kick off 2020 — our popular Water 101
Workshop, scheduled for Feb. 20 at McGeorge School of Law in
Sacramento, and our Lower Colorado River Tour, which will run
from March 11-13.
In addition, applications will be available by the first week of
October for our 2020 class of Water Leaders, our competitive
yearlong program for early to mid-career up-and-coming water
professionals. To learn more about the program, check out our
Water Leaders program

High in the headwaters of the Colorado River, around the hamlet of Kremmling, Colorado, generations of families have made ranching and farming a way of life, their hay fields and cattle sustained by the river’s flow. But as more water was pulled from the river and sent over the Continental Divide to meet the needs of Denver and other cities on the Front Range, less was left behind to meet the needs of ranchers and fish.
“What used to be a very large river that inundated the land has really become a trickle,” said Mely Whiting, Colorado counsel for Trout Unlimited. “We estimate that 70 percent of the flow on an annual average goes across the Continental Divide and never comes back.”
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
We have an unknown distance yet to run, an unknown river to explore. What falls there are, we know not; what rocks beset the channel, we know not; what walls ride over the river, we know not. Ah, well! We may conjecture many things.
~John Wesley Powell
Powell scrawled those words in his journal as he and his expedition paddled their way into the deep walls of the Grand Canyon on a stretch of the Colorado River in August 1869. Three months earlier, the 10-man group had set out on their exploration of the iconic Southwest river by hauling their wooden boats into a major tributary of the Colorado, the Green River in Wyoming, for their trip into the “great unknown,” as Powell described it.
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.
Bruce Babbitt, the former Arizona
governor and secretary of the Interior, has been a thoughtful,
provocative and sometimes forceful voice in some of the most
high-profile water conflicts over the last 40 years, including
groundwater management in Arizona and the reduction of
California’s take of the Colorado River. In 2016, former
California Gov. Jerry Brown named Babbitt as a special adviser to
work on matters relating to the Sacramento-San Joaquin Delta and
the Delta tunnels plan.
For the bulk of her career, Jayne
Harkins has devoted her energy to issues associated with the
management of the Colorado River, both with the U.S. Bureau of
Reclamation and with the Colorado River Commission of Nevada.
Now her career is taking a different direction. Harkins, 58, was
appointed by President Trump last August to take the helm of the
United States section of the U.S.-Mexico agency that oversees
myriad water matters between the two countries as they seek to
sustainably manage the supply and water quality of the Colorado
River, including its once-thriving Delta in Mexico, and other
rivers the two countries share. She is the first woman to be
named the U.S. Commissioner of the International Boundary and
Water Commission for either the United States or Mexico in the
commission’s 129-year history.

Imported water from the Sierra
Nevada and the Colorado River built Southern California. Yet as
drought, climate change and environmental concerns render those
supplies increasingly at risk, the Southland’s cities have ramped
up their efforts to rely more on local sources and less on
imported water.
Far and away the most ambitious goal has been set by the city of
Santa Monica, which in 2014 embarked on a course to be virtually
water independent through local sources by 2023. In the 1990s,
Santa Monica was completely dependent on imported water. Now, it
derives more than 70 percent of its water locally.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
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
ahead.
The latest sobering assessment landed the day after Thanksgiving,
when U.S. Global Change Research Program’s Fourth National Climate
Assessment concluded that Earth’s climate is changing rapidly
compared to the pace of natural variations that have occurred
throughout its history, with greenhouse gas emissions largely the
cause.
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.
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.
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.
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.
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
California.
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.
As California embarks on its unprecedented mission to harness groundwater pumping, the Arizona desert may provide one guide that local managers can look to as they seek to arrest years of overdraft.
Groundwater is stressed by a demand that often outpaces natural and artificial recharge. 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.
We explored the lower Colorado River where virtually every drop
of the river is allocated, yet demand is growing from myriad
sources — increasing population, declining habitat, drought and
climate change.
The 1,450-mile river is a lifeline to 40 million people in
the Southwest across seven states and Mexico. How the Lower Basin
states – Arizona, California and Nevada – use and manage this
water to meet agricultural, urban, environmental and industrial
needs was the focus of this tour.

Dramatic swings in weather patterns
over the past few years in California are stark reminders of
climate variability and regional vulnerability. Alternating years
of drought and intense rain events make long-term planning for
storing and distributing water a challenging task.
Current weather forecasting capabilities provide details for
short time horizons. Attend the Paleo Drought
Workshop in San Pedro on April 19 to learn more about
research efforts to improve sub-seasonal to seasonal
precipitation forecasting, known as S2S, and how those models
could provide more useful weather scenarios for resource
managers.
A drought has lingered in the
Colorado River Basin since 2000, causing reservoir storage to
decline from nearly full to about half of capacity. So far this
year, a meager snowpack in the Rocky Mountains hasn’t helped
much.
In fact, forecasters say this winter will likely go down as the
sixth-driest on record for the river system that supplies water
to seven states, including California, and Mexico.
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.
California’s 2012-2016 drought
revealed vulnerabilities for water users throughout the state,
and the long-term record suggests more challenges may lie ahead.
An April 19
workshop in San Pedro will highlight new information about
drought durations in Southern California watersheds dating
back centuries.
Most people see the Grand Canyon from the rim, thousands of feet above where the Colorado River winds through it for almost 300 miles.
But to travel it afloat a raft is to experience the wondrous majesty of the canyon and the river itself while gaining perspective about geology, natural beauty and the passage of time.
Beginning at Lees Ferry, some 30,000 people each year launch downriver on commercial or private trips. Before leaving, they are dutifully briefed by a National Park Service ranger who explains to them about the unique environment that awaits them, how to keep it protected and, most importantly, how to protect themselves.
They also are told about the pair of ravens that will inevitably follow them through the canyon, seizing every opportunity to scrounge food.
Tickets are now on sale for the Water Education Foundation’s April 11-13 tour of the Lower Colorado River.
Don’t miss this opportunity to visit key sites along one of the nation’s most famous rivers, including a private tour of Hoover Dam, Central Arizona Project’s Mark Wilmer pumping plant and the Havasu National Wildlife Refuge. The tour also visits the Salton Sea, Slab City, the All-American Canal and farming regions in the Imperial and Coachella valleys.
Drought and climate change are having a noticeable impact on the
Colorado River Basin, and that is posing potential challenges to
those in the Southwestern United States and Mexico who rely on
the river.
In the just-released Winter 2017-18 edition of River
Report, writer Gary Pitzer examines what scientists
project will be the impact of climate change on the Colorado
River Basin, and how water managers are preparing for a future of
increasing scarcity.
Rising temperatures from climate change are having a noticeable
effect on how much water is flowing down the Colorado River. Read
the latest River Report to learn more about what’s
happening, and how water managers are responding.
This issue of Western Water discusses the challenges
facing the Colorado River Basin resulting from persistent
drought, climate change and an overallocated river, and how water
managers and others are trying to face the future.
This three-day, two-night tour explored the lower Colorado River
where virtually every drop of the river is allocated, yet demand
is growing from myriad sources — increasing population,
declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in
the Southwest across seven states and Mexico. How the Lower Basin
states – Arizona, California and Nevada – use and manage this
water to meet agricultural, urban, environmental and industrial
needs is the focus of this tour.

The Colorado River Delta once spanned nearly 2 million acres and
stretched from the northern tip of the Gulf of California in
Mexico to Southern California’s Salton Sea. Today it’s one-tenth
that size, yet still an important estuary, wildlife habitat and
farming region even though Colorado River flows rarely reach the
sea.
Since 2000, the Colorado River Basin has experienced an historic,
extended drought causing reservoir storage in the Colorado River
system to decline from nearly full to about half of capacity. For
the Lower Basin, a key point has been to maintain the level of
Lake Mead to prevent a shortage declaration.
A healthy snowfall in the Rockies has reduced the odds of a
shortage this year, but the basin states still must come to terms
with a static supply and growing demands, as well as future
impacts from climate change.
On our Lower
Colorado River Tour, April 5-7, you will meet with water
managers from the three Lower Basin states: Nevada, Arizona and
California. Federal, state and local agencies will update you on
the latest hydrologic conditions and how recent storms might
change plans for water supply and storage.
A troublesome invasive species is
the quagga mussel, a tiny freshwater mollusk that attaches itself
to water utility infrastructure and reproduces at a rapid rate,
causing damage to pipes and pumps.
First found in the Great Lakes in 1988 (dumped with ballast water
from overseas ships), the quagga mussel along with the zebra
mussel are native to the rivers and lakes of eastern Europe and
western Asia, including the Black, Caspian and Azov Seas and the
Dneiper River drainage of Ukraine and Ponto-Caspian
Sea.
This issue of Western Water examines the ongoing effort
between the United States and Mexico to develop a
new agreement to the 1944 Treaty that will continue the
binational cooperation on constructing Colorado River
infrastructure, storing water in Lake Mead and providing instream
flows for the Colorado River Delta.
As vital as the Colorado River is to the United States and
Mexico, so is the ongoing process by which the two countries
develop unique agreements to better manage the river and balance
future competing needs.
The prospect is challenging. The river is over allocated as urban
areas and farmers seek to stretch every drop of their respective
supplies. Since a historic treaty between the two countries was
signed in 1944, the United States and Mexico have periodically
added a series of arrangements to the treaty called minutes that
aim to strengthen the binational ties while addressing important
water supply, water quality and environmental concerns.
Lake Havasu is a reservoir on the Colorado River that supplies
water to the Colorado River
Aqueduct and Central Arizona Project. It is located at
the California/Arizona border, approximately 150 miles southeast
of Las Vegas, Nevada and 30 miles southeast of Needles,
California.
Situated in southwest Riverside County near the Santa Ana
Mountains – about 60 miles southeast of Los Angeles – Lake
Mathews is a
major reservoir in Southern California.
As one of the most productive agricultural regions in the world,
the Imperial Valley
receives its water from the Colorado River via the
All-American Canal. Rainfall is scarce in the desert region at
less than three inches per year and groundwater is of little
value.
This issue looks at the historic drought that has gripped the
Colorado River Basin since 2000 and discusses the lessons
learned, the continuing challenges and what the future might
hold.
The dramatic decline in water levels in Lake Mead and Lake Powell
is perhaps the most visible sign of the historic drought that has
gripped the Colorado River Basin for the past 16 years. In 2000,
the reservoirs stood at nearly 100 percent capacity; today, Lake
Powell is at 49 percent capacity while Lake Mead has dropped to
38 percent. Before the late season runoff of Miracle May, it
looked as if Mead might drop low enough to trigger the first-ever
Lower Basin shortage determination in 2016.

This issue looks at the dilemma of the shrinking Salton Sea. The
shallow, briny inland lake at the southeastern edge of California
is slowly evaporating and becoming more saline – threatening the
habitat for fish and birds and worsening air quality as dust from
the dry lakebed is whipped by the constant winds.

After much time, study and investment, the task of identifying
solutions to ensure the long-term sustainability of the Colorado
River is underway. People from the Upper and Lower basins
representing all interest groups are preparing to put their
signatures to documents aimed at ensuring the river’s vitality
for the next 50 years and beyond.
This 3-day, 2-night tour followed the course of the
lower Colorado River through Nevada, Arizona and California, and
included a private tour of Hoover Dam.
This issue updates progress on crafting and implementing
California’s 4.4 plan to reduce its use of Colorado River water
by 800,000 acre-feet. The state has used as much as 5.2 million
acre-feet of Colorado River water annually, but under pressure
from Interior Secretary Bruce Babbitt and the other six states
that share this resource, California’s Colorado River parties
have been trying to close the gap between demand and supply. The
article – delayed to include the latest information from
Babbitt’s Dec.
This issue updates progress on California’s Colorado River Water
Use Plan (commonly called the 4.4 Plan ), with a special focus on
the Salton Sea restoration/water transfer dilemma. It also
includes information on the proposed MWD-Palo Verde Irrigation
District deal, the Colorado River Delta, and the legislative
debate in the national and state capitals.
With passage of the original Dec. 31, 2002, deadline to have a
Quantification Settlement Agreement (QSA) in place for the
Colorado River, California suffered a cutback in the surplus
Colorado River flows it had relied upon by years. Further
negotiations followed in an attempt to bring the California
parties to an agreement. This issue examines the history leading
to the QSA, the state of affairs of the so-called 4.4 Plan as of
early March, and gives readers a clearer crystal ball with which
to speculate about California’s water future on the Colorado
River.
This issue of Western Water provides the latest information on
some of the philosophical, political and practical ideas being
discussed on the river. Some of these issues were discussed at
the Water Education Foundation’s Colorado River Symposium, “The
Ties that Bind: Policy and the Evolving Law of the Colorado
River,” held last fall at The Bishop’s Lodge in Santa Fe, New
Mexico – site of negotiations on the 1922 Colorado River Compact.
This issue of Western Water explores the issues
surrounding and the components of the Colorado River Basin
seven-state proposed agreement released Feb. 3 regarding sharing
shortages on the river, and new plans to improve the river’s
management. The article includes excerpts from the Foundation’s
September 2005 Colorado River Symposium held in Santa Fe, New
Mexico.
This issue of Western Water marks the 85th anniversary of the
Colorado River Compact and considers its role in the past and
present on key issues such as federal funding for water projects
and international issues. Much of the content for this magazine
came from the Foundation’s September Colorado River Symposium,
The Colorado River Compact at 85 and Changes on the River.
This card includes information about the Colorado River, who uses
the river, how the river’s water is divided and other pertinent
facts about this vital resource for the Southwest. Beautifully
illustrated with color photographs.
In 1997, the Foundation sponsored a three-day, invitation-only
symposium at Bishop’s Lodge, New Mexico, site of the 1922
Colorado River Compact signing, to discuss the historical
implications of that agreement, current Colorado River issues and
future challenges. The 204-page proceedings features the panel
discussions and presentations on such issues as the Law of the
River, water marketing and environmental restoration.

Redesigned in 2017, this beautiful map depicts the seven
Western states that share the Colorado River with Mexico. The
Colorado River supplies water to nearly 40 million people in
Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming
and Mexico. Text on this beautiful, 24×36-inch map, which is
suitable for framing, explains the river’s apportionment, history
and the need to adapt its management for urban growth and
expected climate change impacts.
This 24×36 inch poster, suitable for framing, illustrates the
water resources available for Nevada cities, agriculture and the
environment. It features natural and manmade water resources
throughout the state, including the Truckee and Carson rivers,
Lake Tahoe, Pyramid Lake and the course of the Colorado River
that forms the state’s eastern boundary.
The 28-page Layperson’s Guide to Water Rights Law, recognized as
the most thorough explanation of California water rights law
available to non-lawyers, traces the authority for water flowing
in a stream or reservoir, from a faucet or into an irrigation
ditch through the complex web of California water rights.
The 20-page Layperson’s Guide to Water Marketing provides
background information on water rights, types of transfers and
critical policy issues surrounding this topic. First published in
1996, the 2005 version offers expanded information on
groundwater banking and conjunctive use, Colorado River
transfers and the role of private companies in California’s
developing water market.

The 24-page Layperson’s Guide to California Water provides an
excellent overview of the history of water development and use in
California. It includes sections on flood management; the state,
federal and Colorado River delivery systems; Delta issues; water
rights; environmental issues; water quality; and options for
stretching the water supply such as water marketing and
conjunctive use. New in this 10th edition of the guide is a
section on the human need for water.

Our 24×36-inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
This 3-day, 2-night tour follows the course of the lower Colorado River through Nevada, Arizona and California, and includes a private tour of Hoover Dam.
As part of the historic Colorado
River Delta, the Salton Sea regularly filled and dried for
thousands of years due to its elevation of 237 feet below
sea level.
The most recent version of the Salton Sea was formed in 1905 when
the Colorado River broke
through a series of dikes and flooded the seabed for two years,
creating California’s largest inland body of water. The
Salton Sea, which is saltier than the Pacific Ocean, includes 130
miles of shoreline and is larger than Lake Tahoe.
The Quantification Settlement Agreement (QSA), signed in 2003,
defined the rights to a portion of Colorado River water for the San
Diego County Water Authority, Coachella Valley Water District,
Imperial Irrigation District and the Metropolitan Water District
of Southern California.
The QSA responded to California consistently using more than its
annual Colorado River entitlement of 4.4 million acre-feet.
Additionally, the water needs of six other Colorado River Basin
states had grown, making the river’s shared use increasingly
crucial.
The Mexican Water Treaty of 1944 committed the U.S. to deliver
1.5 million acre-feet of water to Mexico on an annual basis, plus
an additional 200,000 acre-feet under surplus conditions. The
treaty is overseen by the International Boundary and Water
Commission.
Colorado River water is delivered to Mexico at Morelos Dam,
located 1.1 miles downstream from where the California-Baja
California land boundary intersects the river between the town of
Los Algodones in northwestern Mexico and Yuma County, Ariz.
The Colorado River Delta is located
at the natural terminus of the Colorado River at the Gulf of
California, just south of the U.S.-Mexico border. The desert
ecosystem was formed by silt flushed downstream from the Colorado
and fresh and brackish water mixing at the Gulf.
The Colorado River Delta once covered 9,650 square miles but has
shrunk to less than 1 percent of its original size due to
human-made water diversions.
In 2005, the Interior Department launched a program to recover 27
species in the lower Colorado
River, including seven the federal government has deemed
threatened or endangered or threatened with extinction. The
species include fish, birds, bats, mammals, insects, amphibians,
reptiles, rodents and plants
The Lower Colorado River Multispecies Conservation Program has a
50-year plan to create at least 8,132 acres of new habitat
and restore habitat that has become degraded.
Lee Ferry on the Arizona-Utah border is a key dividing point
between the Colorado River’s Upper and Lower basins.
This split is important when it comes to determining how much
water will be delivered from the Upper Basin to the Lower Basin
[for a description of the Upper and Lower basins, visit the
Colorado River page].
The construction of Glen Canyon Dam
in 1964 created Lake Powell. Both are located in north-central
Arizona near the Utah border. Lake Powell acts as a holding tank
for outflow from the Colorado River Upper Basin States: Colorado,
New Mexico, Utah and Wyoming.
The water stored in Lake Powell is used for recreation, power
generation and delivering water to the Lower Basin states of
California, Arizona, and Nevada.
John Wesley Powell (1834-1902) was historic and heroic for being
first to lead an expedition down the Colorado River in 1869. A major
who lost an arm in the Civil War Battle of Shiloh, he was an
explorer, geologist, geographer and ethnologist.
California’s Colorado River Water Use Plan (known colloquially as
the 4.4 Plan) intends to wean the state from its reliance on the
surplus flows from the river and return California to its annual
4.4 million acre-feet basic apportionment of the river.
In the past, California has also used more than its basic
apportionment. Consequently, the U.S. Department of
Interior urged California to devise a plan to reduce its water
consumption to its basic entitlement.
In 2005, after six years of severe
drought in the Colorado River Basin, federal officials and
representatives of the seven basin states — California, Arizona,
Nevada, New Mexico, Colorado, Utah and Wyoming — began building a
framework to better respond to drought conditions and coordinate
the operations of the basin’s two key reservoirs, Lake Powell and
Lake Mead.
The resulting Interim Guidelines for Lower Basin Shortages and
the Coordinated Operations for Lake Powell and Lake Mead (Interim
Guidelines) identified the conditions for shortage determinations
and details of coordinated reservoir operations. The 2007 Interim
Guidelines remain in effect through Dec. 31, 2025.
The turbulent Colorado River is one
of the most heavily regulated and hardest working rivers in the
world.
Geography
The Colorado falls some 10,000 feet on its way from the Rocky
Mountains to the Gulf of California, helping to sustain a range
of habitats and ecosystems as it weaves through mountains and
deserts.
This printed issue of Western Water examines how the various
stakeholders have begun working together to meet the planning
challenges for the Colorado River Basin, including agreements
with Mexico, increased use of conservation and water marketing,
and the goal of accomplishing binational environmental
restoration and water-sharing programs.
This printed issue of Western Water examines the
Colorado River Basin Water Supply and Demand Study and what its
finding might mean for the future of the lifeblood of the
Southwest.
The Colorado River is one of the most heavily relied upon water
supply sources in the world, serving 35 million people in seven
states and Mexico. The river provides water to large cities,
irrigates fields, powers turbines to generate electricity,
thrills recreational enthusiasts and serves as a home for birds,
fish and wildlife.
This printed issue of Western Water explores the
historic nature of some of the key agreements in recent years,
future challenges, and what leading state representatives
identify as potential “worst-case scenarios.” Much of the content
for this issue of Western Water came from the in-depth
panel discussions at the Colorado River Symposium. The Foundation
will publish the full proceedings of the Symposium in 2012.
This printed issue of Western Water examines the
Colorado River drought, and the ongoing institutional and

This printed issue of Western Water explores some of the major
challenges facing Colorado River stakeholders: preparing for
climate change, forging U.S.-Mexico water supply solutions and
dealing with continued growth in the basins states. Much of the

panel discussions at the September 2009 Colorado River Symposium.
This printed copy of Western Water examines the Colorado River
Delta, its ecological significance and the lengths to which
international, state and local efforts are targeted and achieving

This issue of Western Water asks whether a groundwater
compact is needed to manage this shared resource today. In the
water-stressed West, there will need to be a recognition of
sharing water resources or a line will need to be drawn in the
sand against future growth.
“In the West, when you touch water, you touch
everything.” – Rep. Wayne Aspinall, D-Colorado, chair,
House Interior and Insular Affairs Committee, 1959-1973
Rapid population growth and chronic droughts could augur dramatic
changes for communities along the lower Colorado River. In
Arizona, California and Nevada, a robust economy is spurring
communities to find enough water to sustain the steady pace of
growth. Established cities such as Las Vegas and Phoenix continue
their expansion but there is also activity in smaller, rural
areas on Arizona’s northwest fringe where developers envision
hundreds of thousands of new homes in the coming decades.
With interstate discussions of critical Colorado River issues
seemingly headed for stalemate, Secretary of the Interior Gale
Norton stepped in May 2 to defuse, or at least defer, a
potentially divisive debate over water releases from Lake Powell.
With interstate discussions of critical Colorado River issues
seemingly headed for stalemate, Secretary of the Interior Gale
Norton stepped in May 2 to defuse, or at least defer, a
potentially divisive debate over water releases from Lake Powell.
In a letter to governors of the seven Colorado River Basin
states, Norton preserved the status quo of river operations for
five months, giving states and stakeholders a chance to move back
from the edge before positions had hardened on two key issues:
(1) shortage guidelines for the Lower Basin and (2) Upper Basin/
Lower Basin reservoir operations, particularly at Lake Powell.
But Norton served notice that she wants discussions on those two
issues to continue, possibly outside of the annual operation plan
(AOP) consultation process, which at least one observer described
as unwieldy.
Drawn from a special Colorado River stakeholder symposium held in
January 2002 at The Bishop’s Lodge in Santa Fe, New Mexico, this
article provides an overview of several Colorado River issues
that may or may not be resolved through consensus. Some of these
issues include providing water for the Colorado River Delta,
endangered species, dam re-operation and potential future trends
around the basin as they relate to the California 4.4 Plan,
drought and governance.
The situation is true anywhere: when resources are stretched,
tensions rise. In the arid Southwestern United States, this
resource is water and tensions over it have been ever present
since the westward migration in the 18th Century. Nowhere in this
region has the competition for water been fiercer than in the
Colorado River Basin. Whether it is more water for agriculture,
more water for cities, more water for American Indian tribes or
more water for the environment – there is a continuous quest by
parties to obtain additional supplies of this “liquid gold” from
the Colorado River. Sometimes the avenue chosen to acquire this
desert wealth is the court system, as exemplified by the landmark
Arizona v. California dispute that stretched for over 30 years.
Drawn from a special stakeholder symposium held in September 1999
in Keystone, Colorado, this issue explores how we got to where we
are today on the Colorado River; an era in which the traditional
water development of the past has given way to a more
collaborative approach that tries to protect the environment
while stretching available water supplies. Specific topics
addressed include the role of the Interior secretary in the
basin, California’s 4.4 plan, water marketing and future
challenges identified by participants.
