Mohave, Coconino, Yavapai, & La Paz County

Mohave, Coconino, Yavapai, La Paz – 4 county boards of supervisors unanimously passed resolutions calling for the governor and the legislature to take action on advancing rural management of groundwater. 



ARIZONA'S WATER SUPPLIES: Over the last decade and a half, the Southwest has experienced significant drought conditions. These conditions can lead to changes in our state's water supply availability. Fortunately, Arizona has developed a diverse portfolio of water supplies and management strategies which serve as the foundation of our State's robust water system. This diversity allows Arizona to more effectively manage water resources, allows the state to subsist with the effects of existing drought conditions and provides more options in planning for our states future economic growth.



The Kyl Center for Water Policy developed this tool to show groundwater level changes across the state's sub-basins for 1-year (2017-18), 10-year (2008-18) and 20-year (1998-2018) time periods. The data for these features come primarily from the Arizona Department of Water Resources (ADWR) Statewide Groundwater Level Changes report (Open-File Report No.18, December 2020).

The operation of Lake Powell and Lake Mead in this July 2021 24-Month Study is pursuant to the December 2007 Record of Decision on Colorado River Interim Guidelines for Lower Basin Shortages and the Coordinated Operations of Lake Powell and Lake Mead (Interim Guidelines), and reflects the 2021 Annual Operating Plan (AOP). Pursuant to the Interim Guidelines, the August 2020 24-Month Study projections of the January 1, 2021, system storage and reservoir water surface elevations set the operational tier for the coordinated operation of Lake Powell and Lake Mead during 2021.

The iconic images of the bathtub ring around Lake Mead caused by falling water levels have been viewed by millions around the country and the world. Lake Mead has become the symbol of what happens when climate change meets over-allocation of a fragile water supply. Seeing is believing, and there is now a near-universal belief that changes are needed to help sustain the Colorado River.



The terms drought and shortage are routinely used together when talking about Arizona's hot and arid climate. While both drought and shortage involve a lack of water, their circumstances, impacts, and the challenges they bring differ.

ARIZONA – STRONGER TOGETHER. As we face the prospect of a hotter and drier future, we are confident that with our long history of successful collaboration among our diverse stakeholders – agriculture, tribes, cities, environment and industry – we will continue to find innovative and effective solutions to sustain Arizona’s Colorado River supply.

Arizona Institutes for Resilience

Perspectives on Regional Water Sustainability. Water for Arizona Coalition member, Haley Paul joins Arizona Institutes for Resilience to discuss how we should define water sustainability in an era of climate change, and shifts in socio-economic conditions and community priorities. What does water sustainability look like in the Colorado River basin? What are the paths forward to more inclusive solutions?



A joint message from the Arizona Department of Water Resources and Central Arizona Project. As the drought in the Colorado River Basin extends beyond its 20th year, we anticipate the first-ever shortage declaration on the Colorado River. The shortage will result in a substantial cut to Arizona’s share of the river, with reductions falling largely to central Arizona agricultural users.

Center for Colorado River Studies 

Alternative Management Paradigms for the Future of the Colorado and Green Rivers. 

Our ability to sustainably manage the Colorado River is clearly in doubt. The Bureau of Reclamation’s 2012 Water Supply and Demand Study demonstrated the precarious balance that currently exists between water supply and the amount consumptively used by society.



Jointly issued by: ADEQ, ADWR, AMWUA, CAP, SRP

Water is critical to public health, our quality of life, the desert environment and our economy. That is why we are all doing our part to ensure you always have water at your tap, even during times of concern.

We have planned and invested in robust and resilient water supplies, infrastructure and processes so that your local water provider can deliver you water every day of every year. 



CAP begins 2021 with eye on CAWCD’s new Board Strategic Plan

At its December board meeting, the Central Arizona Water Conservation District Board of Directors unanimously approved a new Strategic Plan.

The process to develop the Plan began in late 2019 and included Board interviews and retreats, stakeholder forums and employee surveys. More than 35 organizations participated and provided input into the strategic planning process.

Doing the Dishes

Arizona State University

New research director for Kyl Center focused on equity in water access. 

“Access to clean water is a fundamental need of every person on Earth, and yet we're still so far from fulfilling that need, even in Arizona. I want the research and teaching I do at ASU to help us overcome the barriers that prevent people from having secure access to safe water.”



Leading Through Collaboration and Cooperation. With foresight and an understanding of the water challenges that life in the desert can bring, mayors from Valley cities gathered to discuss how to work together on water issues more than 50 years ago. They then formed a unique and innovative partnership – the Arizona Municipal Water Users Association (AMWUA). Over time it would become a collaboration of ten member municipalities working for the common purpose of safeguarding water resources in the Valley.



2020 Year In Review: Overcoming Pandemic Hurdles To Continue Serving The Public. In terms of water management, the “success story” of 2019 couldn’t have been bigger. Arizona lawmakers and Gov. Doug Ducey approved the Arizona Drought Contingency Plan in January of that year, and, months later, Arizona joined the other Colorado River Basin states and the federal government in signing the agreements dedicated to help stabilize the vital river system.



To ensure we have water not only today, but for the long-term, our diligence and work never ends, and 2021 will certainly be no exception. While we know the Colorado River will receive much attention this year, other important issues must also be addressed, including our future groundwater management.


Walton Family Foundation

Colorado’s food producers are protecting water supply for the benefit of the economy and environment. Disruptions to our daily lives have a way of making us appreciate things that we might normally take for granted. In the midst of a global pandemic, access to clean water and healthy food seems more vital than ever. This extraordinary situation motivates us all to take a step back to examine what we can do to ensure the long-term security of our most precious natural resources.



The Central Arizona Water Conservation District Board of Directors (CAWCD) convened virtually on Thursday, Jan. 7, 2021 for its January 2021 board meeting. CAWCD Board President Lisa Atkins chaired the meeting from the headquarters boardroom and all other board members participated via WebEx. The public was invited to watch the livestream and to provide public comment. CAWCD Board meetings will be held virtually through at least March 2021, in accordance with CAP’s headquarters closure to keep employees safe and water flowing during the COVID-19 pandemic.

Attitudes and Opinions About Environmental Issues in Arizona. A representative sample of 800 Arizona registered voters was surveyed in March 2017 and again in January 2020 (separate samples) to gauge Arizona voters’ attitudes toward and beliefs about the environment and environmental protection. Morrison Institute for Public Policy at ASU designed the questionnaire, compiled the data and conducted the analysis for Nina Mason Pulliam Charitable Trust.



Healthy Infrastructure Makes our Communities Stronger. Our cities’ infrastructure is vital to making our daily lives function smoothly. Of all infrastructure types, water systems are the most fundamental to life by providing the delivery of safe and clean water to households, industries, and businesses. Water is critical to our health and is essential to our way of life and a thriving economy.



New ADWR Tool To Help AMA Stakeholders Participate In Development Of 5th Management Plans. When the nation’s most ambitious state law designed to protect groundwater resources came into being in 1980, a key element of that law was its series of “management plans.”



Behind every drop of water that comes from your tap is a vast and complicated system of technology, logistics, and engineering that ensures you always have water on-demand and at the highest levels of safety and quality. Once your water provider has treated water to safe drinking water standards, it is delivered to homes and businesses. An important part of this process is a complex tracking system for your water utility to account for the billions of gallons they deliver each year.

No Surprises: Drought Group Again Recommends Governor Extend Drought Emergency Declaration.

Other than sunrise and sunset, the world provides precious few “sure things.”So, maybe it was not an absolute sure thing that Arizona’s Drought Interagency Coordinating Group would recommend to the Governor that the State’s drought-emergency declaration should be extended once again.



The U.S. Bureau of Reclamation has issued its August 24-Month Study. The purpose of this study is to project the year-end elevation of Lake Mead, which in turn determines the 2021 Lower Basin water supply conditions for CAP. BOR projects the Lake Mead elevation will be 1085.3’ on Jan. 1, 2021, which signals the Tier Zero supply of Colorado River water will continue for 2021.



On July 25, 2019, the Glen Canyon Dam Adaptive Management Program, or GCDAMP, sponsored an eight-day Colorado River raft trip through the Grand Canyon for the organization’s stakeholders, which include members of government and science-oriented agencies whose duties include conditional analysis and research of the river.



All across the West, we are all feeling the effects of the record-breaking heat and lack of precipitation. In addition to the obvious consequences, what do the high temperatures and lack of moisture really mean for water sources such as the already compromised Colorado River?

The operation of Lake Powell and Lake Mead in this August 2020 24-Month Study is pursuant to the December 2007 Record of Decision on Colorado River Interim Guidelines for Lower Basin Shortages and the Coordinated Operations of Lake Powell and Lake Mead (Interim Guidelines), and reflects the 2020 Annual Operating Plan (AOP). 



Part II: Safe-yield has been a valuable goal to motivate water users to focus on groundwater sustainability, which has led to progress in the Phoenix Active Management Area (AMA) over the first 40 years following the Groundwater Management Act (GMA). Now is the time to consider if more comprehensive goals are needed for us to address all of our current groundwater issues effectively.



Now, the Arizona Department of Water Resources (ADWR) and Central Arizona Project (CAP) are using this same approach to develop an Arizona consensus on the “reconsultation” of the Colorado River Interim Guidelines for Lower Basin Shortages and the Coordinated Operations for Lake Powell and Lake Mead, known as the 2007 Guidelines. 



Through this two-part series on safe-yield, we will look back at the past, acknowledge how far we have come, and discuss the challenges we still collectively face as we move forward. The effectiveness of safe-yield as a water management goal has been periodically questioned throughout the 40 years that have followed the Groundwater Management Act (GMA). 



The Central Arizona Water Conservation District Board of Directors (CAWCD) convened virtually today for its June 2020 meeting. CAWCD Board President Lisa Atkins chaired the meeting from the headquarters boardroom and all other board members participated via WebEx. The public was invited to watch the livestream and to provide public comment via the Board’s online “Blue Card.”



ASU’s Kyl Center for Water Policy held design workshops with over 200 experts in water, land use, environmental and economic development. Input from these experts helped us to create the Arizona Water Blueprint. The Blueprint is a data-rich, interactive map of the state’s water resources and infrastructure. It also offers multimedia content on important water-related topics.



Former Arizona Governor and U.S. Secretary of the Interior Bruce Babbitt created this video to share with the CAWCD Board regarding his reflections on the 40th anniversary of the Groundwater Management Act, a milestone marked on June 12, 2020.



Press Release: A Statement on the 40th Anniversary of Arizona Groundwater Management Act of 1980. June 10, 2020 – Friday, June 12, marks the 40th  anniversary of the Arizona Groundwater Management Act of 1980, the law that changed the trajectory of water use in Arizona.



Wildfires Impact on our Water. Wildfires devastate forest vegetation. They leave behind large amounts of ash, heavy metals, organic materials, and sediments that then flow into the rivers and accumulate in reservoirs. The damage to the watershed significantly affects both the quality and sustainability of the water.



Cities Dedicated to Continued Delivery of Safe and Secure Water. The safety and security of Arizona’s water supplies is a top priority for the ten AMWUA cities. Each AMWUA municipality is committed to ensuring you have water service every day of every year. 



New Colorado River Basin Climate & Hydrology Report May Be Most Valuable Ever. When 40 million people and some of the most fruitful croplands in the world rely heavily on a single source of water, it seems only natural to want to know as much as possible about the source.



CAP faces a variety of biological challenges on a regular basis. While some of these challenges threaten our ability to deliver water, others focus on conserving fish and wildlife that share our resources.

This annual report highlights activities performed throughout the year and identifies future areas of need.



Arizona residents certainly know the value of water. Yet it is easy to forget the complex process and the extensive team of people it takes to get safe and secure water to our tap. And the important role all water professionals play has never been more evident than it is now.

Well Inspection


PHOENIX – The United States Bureau of Reclamation (Reclamation) has released its April 24 Month Study, which projects Colorado River operations for the next two years. The study projects the operating conditions of the Colorado River system, as well as runoff and reservoir conditions.
