Arizona water issues impact all residents of the state...
and surrounding states. Arizona's water supply is of vital importance.
Water not only sustains life, it makes
possible an enjoyable quality of life as it sustains the regional economy.
The strategic analysis report presented here speaks to these issues.

An amendment to a standing water treaty between
the United States and Mexico has received publicity over the past six
months as an example of progress in water sharing agreements. But the
amendment, called Minute 319, is simply a glimpse into ongoing
mismanagement of the Colorado River on the U.S. side of the border.
Over-allocation of the river's waters 90 years ago combined with
increasing populations and economic growth in the river basin have
created circumstances in which conservation efforts -- no matter how
organized -- could be too little to overcome the projected water deficit
that the Colorado River Basin will face in the next 20 years.
In 1922, the seven U.S. states in the Colorado
River Basin established a compact to distribute the resources of the
river. A border between the Upper and Lower basins was defined at Lees
Ferry, Ariz. The Upper Basin (Wyoming, Colorado, Utah and New Mexico)
was allocated 9.25 billion cubic meters a year, and the Lower Basin
(Arizona, California and Nevada) was allotted 10.45 billion cubic
meters. Mexico was allowed an unspecified amount, which in 1944 was
defined as 1.85 billion cubic meters a year. The Upper and Lower basins
-- managed as separate organizations under the supervision of the U.S.
Bureau of Reclamation -- divided their allocated water among the states
in their jurisdictions. Numerous disputes arose, especially in the Lower
Basin, regarding proper division of the water resources. But the use of
(and disputes over) the Colorado River began long before these treaties.
As the United States' territory expanded to the
west, the Colorado River briefly was considered a portal to the isolated
frontier of the southwestern United States, since it was often cheaper
to take a longer path via water to transport goods and people in the
early 19th century. There was a short-lived effort to develop the
Colorado River as the "Mississippi of the West." While places
like Yuma, Ariz., became military and trading outposts, the geography
and erratic flow of the Colorado made the river ultimately unsuitable
for mass transportation. Navigating the river often required maneuvering
around exposed sand banks and through shallow waters. The advent of the
railroad ended the need for river transport in the region. Shortly
thereafter, large and ambitious management projects, including the
Hoover Dam, became the river's main purpose.
Irrigation along the river started expanding in
the second half of the 19th century, and agriculture still consumes more
water from the Colorado than any other sector. Large-scale manipulation
of the river began in the early 20th century, and now there are more
than 20 major dams along the Colorado River, along with reservoirs such
as Lake Powell and Lake Mead, and large canals that bring water to areas
of the Imperial and Coachella valleys in southern California for
irrigation and municipal supplies. User priority on the Colorado River
is determined by the first "useful purposing" of the water.
For example, the irrigated agriculture in California has priority over
some municipal water supplies for Phoenix, Ariz.
Inadequate Supply and Increasing Demand
When the original total allocation of the river
was set in the 1920s, it was far above regional consumption. But it was
also more than the river could supply in the long term. The river was
divided based on an estimated annual flow of roughly 21 billion cubic
meters per year. More recent studies have indicated that the 20th
century, and especially the 1920s, was a time of above-normal flows.
These studies indicate that the long-term average of flow is closer to
18 billion cubic meters, with yearly flows ranging anywhere from roughly
6 billion cubic meters to nearly 25 billion cubic meters. As utilization
has increased, the deficit between flow and allocation has become more
Total allocations of river resources for the Upper
and Lower basins and Mexico plus water lost to evaporation adds up to
more than 21 billion cubic meters per year. Currently, the Upper Basin
does not use the full portion of its allocation, and large reservoirs
along the river can help meet the demand of the Lower Basin. Populations
in the region are expected to increase; in some states, the population
could double by 2030. A study released at the end of 2012 by the U.S.
Bureau of Reclamation predicted a possible shortage of 3 billion cubic
meters by 2035.
The Colorado River provides water for irrigation
of roughly 15 percent of the crops in the United States, including
vegetables, fruits, cotton, alfalfa and hay. It also provides municipal
water supplies for large cities, such as Phoenix, Tucson, Los Angeles,
San Diego and Las Vegas, accounting for more than half of the water
supply in many of these areas. Minute 319, signed in November 2012,
gives Mexico a small amount of additional water in an attempt to restore
the delta region. However, the macroeconomic impact on Mexico is
minimal, since agriculture accounts for the majority of the river's use
in Mexico but only about 3 percent of the gross domestic product of the
Baja Norte province.
There is an imbalance of power along the
international border. The United States controls the headwaters of the
Colorado River and also has a greater macroeconomic interest in
maintaining the supply of water from the river. This can make individual
amendments of the 1944 Treaty somewhat misleading. Because of the
erratic nature of the river, the treaty effectively promises more water
than the river can provide each year. Cooperation in conservation
efforts and in finding alternative water sources on the U.S. side of the
border, not treaty amendments, will become increasingly important as
regional water use increases over the coming decades.
Conservation Efforts Along the Colorado
The U.S. Bureau of Reclamation oversees the whole
river, but the management of each basin is separate. Additionally,
within each basin, there are separate state management agencies and,
within each state, separate regional management agencies. Given the
number of participants, reaching agreements on the best method of
conservation or the best alternative source of water is difficult. There
are ongoing efforts at conservation, including lining canals to reduce
seepage and programs to limit municipal water use. However, there is no
basin-wide coordination. In a 2012 report, the Bureau of Reclamation
compiled a list of suggested projects but stopped short of recommending
a course of action.
A similar report released in 2008 listed 12
general options including desalinization, vegetation management
(elimination of water-intensive or invasive plants), water reuse,
reduced use by power plants and joint management through water banking
(water is stored either in reservoirs or in underground aquifers to use
when needed). Various sources of water imports from other river basins
or even icebergs are proposed as options, as is weather modification by
seeding clouds in the Upper Basin. Implementation of all these options
would result in an extra 5 billion cubic meters of water a year at most,
which could erase the predicted deficit. However, this amount is
unlikely, as it assumes maximum output from each technique and also
assumes the implementation of all proposed methods, many of which are
controversial either politically or environmentally and some of which
are economically unviable. Additionally, many of the methods would take
years to fully implement and produce their maximum capacity. Even then,
a more reasonable estimate of conservation capacity would likely be
closer to 1 billion-2 billion cubic meters, which would fall short of
the projected deficit in 2035.
The Potential for New Disputes
Conflict over water can arise when there are
competing interests for limited resources. This is seen throughout the
world with rivers that traverse borders in places like Central
Asia and North
Africa. For the Colorado River, the U.S.-Mexico border is likely
less relevant to the competition for the river's resources than the
artificial border drawn at Lees Ferry.
Aside from growing populations, increased energy
production from unconventional hydrocarbon sources in the Upper Basin
has the potential to increase consumption. While this amount will likely
be small compared to overall allocations, it emphasizes the value of
water to the Upper Basin. Real or perceived threats to the Upper Basin's
surplus of water could be seen as threats to economic growth in the
region. At the same time, further water shortages could limit the
potential for economic growth in the Lower Basin -- a situation that
would only be exacerbated by growing populations.
While necessary, conservation efforts and the
search for alternative sources likely will not be able to make up for
the predicted shortage. Amendments to the original treaty typically have
been issued to address symptomatic problems. However, the core problem
remains: More water is promised to river users than is available on
average. While this problem has not come to a head yet, there may come a
time when regional growth overtakes conservation efforts. It is then
that renegotiation of the treaty with a more realistic view of the
river's volume will become necessary. Any renegotiation will be filled
with conflict, but most of that likely will be contained in the United

United States and Mexico Celebrate Partnership for
Historic Release of Colorado River Water to Delta,
Benefitting Both Nations
BAJA CALIFORNIA, MEXICO AND YUMA, AZ – Deputy
Secretary of the Interior Michael L. Connor and Assistant
Secretary of the Interior for Water and Science Anne
Castle today joined other senior officials of the United
States and Mexico to celebrate a historic first-time
intentional release of water—called a “pulse flow”—from
Morelos Dam near the U.S.-Mexico border. The water release—which
began on March 23, reaches its peak today and will
continue until mid-May— is part of a broad package of
joint cooperative treaty actions to ensure the Colorado
River system is able to continue to meet the needs of both
“The spirit of cooperation and commitment to protect and
preserve the Colorado River is exemplary, and these
partnerships will inspire future generations to take on
and solve complex challenges involving finite resources,”
said Deputy Secretary Connor, emphasizing the importance
of this experimental flow. “This is the first time in
history that water has flowed below Morelos Dam to aid in
the long-term restoration of the river, and I want to
thank the Mexican and U.S. Sections of the International
Boundary and Water Commission, Interior’s Bureau of
Reclamation, the Colorado River basin states, and all the
U.S. and Mexican organizations involved in making today’s
event happen. ”
The United States and Mexico agreed to the water release
as a result of joint efforts and investments in water
conservation projects in accordance with “Minute 319,”
a 2012 bi-national agreement adopted under the 1944
U.S.-Mexico Treaty framework for sharing the Colorado
River water. All Lower Colorado River Basin users in
theUnited States. and Mexico will continue to receive
their full allocations of Colorado River water in 2014.
The pulse flow, which began on Sunday with the lifting of
one gate at Morelos Dam, will run for eight weeks. More
control gates will open as the dam releases water at
varying amounts and speeds toward the delta, its estuary
and the Sea of Cortez. A volume of 105,392 acre-feet of
water will flow down the river’s channel to help
regenerate native cottonwood and willow habitat. The
experimental flow also is providing the scientific
community the opportunity to gather valuable data from
collaborative monitoring activities; these data will
inform both countries in developing future management
actions regarding water flows in the delta. Scientists
from Interior's U.S. Geological Survey are playing a key
role measuring the hydrologic and ecosystem
response to the pulse flow.
Representatives of federal, state and conservation
organizations from the United States and Mexico have
worked cooperatively since Minute 319 was signed in 2012
to establish a delivery plan for the timing and amounts of
water releases from Hoover Dam for the pulse flow.
“The pulse flow now underway is the first major step in
a series of anticipated actions and cooperative measures
outlined between our two countries,” said Assistant
Secretary Castle. “Today's event celebrates our shared
vision to work together as partners to address the
resources of the Colorado River and its parched Delta.”
Connor and Castle celebrated with other dignitaries
including: Director General for North America from the
Mexican Ministry of Foreign Affairs Ana Luisa Fajer;
Director General of Mexico’s National Commission for
Water, David Korenfeld; U.S. Commissioner Edward Drusina
and Mexico Commissioner Roberto F. Salmon from the
International Boundary and Water Commission; Baja
California Governor Francisco Vega; as well as
representatives from seven U.S. and two Mexican states
that use Colorado River water to sustain their
agriculture, economies, communities and environment.
“A lot of hard work by various teams from Mexico, the
United States, state governments, water districts, and
private organizations has gone into making this pilot
project a reality, and those partnerships are as historic
as this pulse flow,” added Castle. “The results of the
eight-week run of pulse flow will yield ground-breaking
new science for both countries and help improve our
understanding of the river, its delta, and potential

unprecedented water crisis of the American Southwest
A prolonged drought has sapped the
once-vigorous Colorado River, threatening the water supply
Why is the Colorado so important?
It's the lifeline of the arid Southwest. Starting off in
the snowy Rocky Mountains of northern Colorado, the
1,450-mile river snakes its way through the Grand Canyon
and southwest toward Mexico, supplying water to seven
states — California, Nevada, Arizona, Utah, Colorado,
New Mexico, and Wyoming. The river and its tributaries
provide water for 40 million people in hot, thirsty cities
such as Los Angeles, Las Vegas, San Diego, and Phoenix,
while irrigating 4 million acres of farmland stretching
from California's Imperial Valley to Wyoming's cattle
herds. But with the Colorado's flow now reduced to a muddy
trickle in parts, millions in the Southwest face the grave
prospect of acute, permanent water shortages. The river
"is a testament of what happens when we ask too much
of a limited resource," said PBS filmmaker Peter
McBride. "It disappears."
What's causing the problem?
The most immediate cause is 14 years of drought unrivaled
in 1,250 years. Low snowpack in the Rocky Mountains has
diminished the river at its source, while soaring summer
temperatures over 110 degrees have evaporated its waters,
depleted its reservoirs, and dried out huge swaths of soil
— crippling farmers in the process. "I've got corn
plants that are as brown as you could imagine," said
Weld County, Colo., farmer Dave Eckhardt last summer,
after losing more than 400 acres of his 1,400-acre crop.

Arizona’s continued economic prosperity and growth in
its next Century. The Strategic Vision assesses current
and projected demands and water supplies that have been
identified in recent reports and provides potential
strategies that will help Arizona meet its future needs.
Recent studies have identified the potential for a
long-term imbalance between available water supplies and
projected water demands over the next 100 years if no
action is taken. The Strategic Vision creates the
framework for addressing future water supply challenges
and helps to secure sufficient and dependable water
supplies for Arizona. The Strategic Vision has been

Bureau of Reclamation Forecasts Lower Water Release from Lake
Powell to Lake Mead for 2014
SALT LAKE CITY — As part of its ongoing management of Colorado
River reservoirs, the Bureau of Reclamation has determined that,
based on the best available data projections of Lake Powell and Lake
Mead reservoir elevations, under the 2007 Colorado River Interim
Guidelines for Lower Basin Shortages and Coordinated Operations for
Lake Powell and Lake Mead (2007 Interim Guidelines) a release of
7.48 million acre-feet (maf) from Lake Powell is required in water
year 2014 (Oct. 1, 2013 – Sept. 30, 2014).
An annual release of 7.48 maf is the lowest release since the
filling of Lake Powell in the 1960s. Lake Mead is projected to
decline an additional eight feet during 2014 as a result of the
lower Lake Powell annual release; however, Lake Mead will operate
under normal conditions in calendar year 2014, with water users in
the Lower Colorado River Basin and Mexico receiving their full water
orders in accordance with the 2007 Interim Guidelines and the 1944
Treaty with Mexico.
Conservation groups warned Thursday of drastic cutbacks
in water releases from Lake Powell into the Lower Colorado
River because of drought conditions, but state officials
and a Central Arizona Project spokesman sought to downplay
alarm over shortages.
The federal Bureau of Reclamation is expected to
announce today that Lake Powell has dropped for the first
time to a level that would trigger reduced flows into
the Grand Canyon and the Lower Colorado River Basin,
affecting mainly farmers.
Based on projections, CAP officials said water
shortages could hit the Lower Colorado River by 2014 and
trigger a 20 percent decrease in CAP water deliveries for

Environmental Group Names Colorado River "Most
The environmental activist group American Rivers has proclaimed
the top ten "Most Endangered Rivers" in the USA.
Their evaluation states... "Outdated water management
is threatening recreation, water supply, and wildlife habitat."
Their website advocates that citizens tell
Congress to support additional regulations...
Take Action For America's Most Endangered Rivers
Keep the Colorado Flowing
We need to put the Colorado River on the path to recovery. Tell
Congress to support critical programs that address water supply
sustainability in the Colorado River Basin and across the West.
Pumping May Continue to Reduce the Streamflow of the Verde
The streamflow of the Verde Riverone of Arizona's largest
streams with year-round flowdeclined from 1910 to 2005 as
the result of human stresses, primarily groundwater
pumping, according to a new U.S. Geological Survey study.
The study's findings suggest that streamflow reductions
will continue and may increase in the future.
Water demands in the Verde Valley
have increased because of the growing population in the
area. Water is pumped from the ground and diverted from
the Verde River to meet these needs, which has raised
concerns about past, present, and future human-induced
stresses on water resources.
"The results of the study
emphasize our basic understanding of hydrologic systems,
which is that when water is removed by being pumped
through wells, it is no longer available in other parts of
the system," said USGS hydrologist Bradley Garner.
"This study is important because it allows us to
examine human-caused stresses, namely groundwater pumping,
independently from other factors that change over time,
such as annual precipitation rates."
