A Joint ADWR/CAP Statement On CO River Shortage Preparedness

Stronger Together

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.  These reductions are painful, but we are prepared. We have long understood the risks to Arizona’s Colorado River supplies and have been planning for decades, including the successful efforts to create a Drought Contingency Plan for the Colorado River system in 2019. 

It’s important to note that a shortage means a reduction in the Colorado River supply available to Arizona. While we may have less water coming to Arizona from the Colorado River in 2022, the river will continue to be a vital source of water for generations to come.

In 2021, the river is currently operating in a “Tier Zero” status, requiring the state to contribute 192,000 acre-feet of Arizona’s 2.8 million acre-foot annual entitlement to Lake Mead. This contribution is coming entirely from the Central Arizona Project (CAP) system. 

Based on the current hydrology, it is likely that the U.S. Bureau of Reclamation will elevate the shortage level to a “Tier 1” in 2022. This would require Arizona to reduce uses by a total of 512,000 acre-feet, again, borne almost entirely by the CAP system. While significant, the high priority CAP water supply for cities and tribes is not affected due to the implementation of agreements among Arizona water users.

We are prepared for Tier 1 reductions because Arizona water users have been working collaboratively for many years to protect our Colorado River water supply.

Specifically, the seven states in the Colorado River Basin and the U.S., and the Republic of Mexico, developed plans for managing the Colorado River, known in the U.S. as the Drought Contingency Plan (DCP), which lasts until 2026. Arizona prepared a unique and innovative way to implement the plan in Arizona through its DCP Steering Committee. 

The DCP Steering Committee, which included more than 40 representatives of tribes, cities, agriculture, developers, environmental organizations, and elected officials, worked collectively to share the risks and benefits of the DCP.  Arizona’s DCP implementation plan represents the best of Arizona water management: collaboration, cooperation, and innovation. 

The plan shares resources and mitigates the impacts of shortage reductions.  In the plan, some are committing to leaving extra water in Lake Mead to reduce future risks, while others are sharing water with the most severely impacted of the state’s water users, central Arizona agriculture Together these efforts reduce the pain of the near-term reductions while addressing risks of future shortages.  The result is the Arizona water community is prepared, even in the midst of a decades-long drought.

The actions taken by Arizona’s water-community stakeholders, legislature and by Governor Ducey manage the immediate risk to supplies on the Colorado River, providing time while we develop new rules and programs to sustain the river after 2026.

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.

State Climatologist Nancy Selover to Participate in Final Drought Declaration Panel

After 14 years as Arizona’s top analyst of weather data, State Climatologist Nancy Selover has announced her retirement. Effectively if not literally, she has weathered the stormy challenges of being the top weather-and-climate expert in a state that has been dogged by persistent drought throughout her time in office.

A research professor in the School of Geographical Sciences and Urban Planning at Arizona State University, Selover also will retire from her ASU duties, which involve research into urban heat-island effects, microclimate and evaporation.

Her role as State Climatologist, however, is the one that has put her most prominently in the public eye. Appointed in 2007 by then-Governor Janet Napolitano, Dr. Selover has spent countless hours in public forums providing climate data and information about Arizona weather issues to the general public, government agencies, private industry and other researchers.

She has said that her greatest pleasure in the job has been her presentations to schools and community groups, discussing climate and weather topics that impact Arizona and, in her words, “communicating climate science to stakeholders in plain vanilla.”

On Tuesday, May 11 at 10 a.m., Dr. Selover will participate in her final meeting with the Drought Interagency Coordinating Group. At that meeting, the ICG will be asked to make a recommendation to Governor Doug Ducey about whether to maintain the official Drought Declarations that are currently in place.

Information about the May 11 ICG meeting may be found on the Arizona Department of Water Resources website at new.azwater.gov/drought

The following is a recording of a farewell discussion between ADWR’s Arizona Water News and Dr. Selover.

Joint statement from ADWR & CAP on results of the April 24 Month Study

Today the Bureau of Reclamation released its April 24-Month Study, which anticipates conditions on the Colorado River system for the next two years.  The study, while significant, is not a surprise.  It reflects the impacts of the dry and warm conditions across the Colorado River Basin this year, as well as the effects of a prolonged drought that has impacted the Colorado River water supply.  

The results continue to show a very high likelihood of Tier 1 reductions in 2022 and 2023, as well as an increasing risk of Tier 2 conditions in the near future.  We are prepared for these conditions, thanks in large part to Arizona’s unique collaborative efforts among water leaders including tribes, cities, agriculture, industry and environmental organizations that developed innovative conservation and mitigation programs as part of the implementation of the Drought Contingency Plan.  

The DCP was approved by the Arizona Legislature and signed by Governor Ducey in early 2019 and almost immediately demonstrated its value. Its implementation offset potentially deeper cuts in Arizona’s Colorado River allocation beyond the 192,000 acre-feet that the State annually has stored in Lake Mead for several years.

We will outline the details of those efforts at a joint public briefing on April 29. Arizona water leaders are continuing to work together within Arizona and with partners across the Colorado River basin to develop new approaches to protect and sustain our Colorado River water supply now and into the future.

On the frontlines with ADWR during National Groundwater Awareness Week

Before ADWR Field Services can conduct their examinations of the current condition and depth of wells drilled in Arizona, all the data about the wells themselves must be compiled and organized by the Department’s Groundwater Permitting and Wells division. That enormous task of compiling and organizing data on Arizona’s estimated 200,000 wells is managed by Stella Murillo, who spoke about her division’s duties during National Groundwater Awareness Week.

On the frontlines with ADWR during National Groundwater Awareness Week

More than perhaps any other state agency, the Arizona Department of Water Resources is committed to the protection of our State’s groundwater resources. We are a creation of one of the most far-sighted laws in the nation created in defense of its groundwater — the Arizona Groundwater Management Act of 1980 — and we take that mission to defend Arizona’s water resources seriously. No agency is more… aware of the importance of groundwater than ADWR.
In this podcast recognizing National Groundwater Awareness Week, we have asked an ADWR employee on the front lines of groundwater management about his duties, and about what those tasks mean to him. Scott Stuk is head of ADWR’s basic-data group in the Field Services Division. Scott took a few moments during Groundwater Awareness Week to talk about what he does for a living… and what he believes it means to Arizona.

Arizona Department of Water Resources field hydrologists conducting “basin sweep” to collect water level measurements in the Dripping Spring Wash, Aravaipa Canyon, Donnelly Wash and Lower San Pedro Basins

FOR IMMEDIATE RELEASE                                                         March 11, 2021

Arizona Department of Water Resources field hydrologists conducting “basin sweep” to collect water level measurements in the Dripping Spring Wash, Aravaipa Canyon, Donnelly Wash and Lower San Pedro Basins

PHOENIX – Beginning the week of March 8, 2021, and continuing for several months, Arizona Department of Water Resources (ADWR) field services staff will be making an extensive effort to measure water levels in wells in the Dripping Spring Wash, Aravaipa Canyon, Donnelly Wash and Lower San Pedro Basins.  ADWR staff will attempt to measure water levels at hundreds of wells in these groundwater basins.  This survey of wells – or basin “sweep,” as it is known — will be the first such basin survey since 2006 for the Lower San Pedro Basin and since 1996 for Dripping Spring Wash, Aravaipa Canyon, and Donnelly Wash Basins. The data collected will be analyzed and used to obtain a comprehensive overview of the groundwater conditions, as well as to support scientific and water management planning efforts. Data collected will be used for several purposes, including:

  • Analysis of water-level trends
  • Groundwater modeling
  • Water-level change maps
  • Hydrologic reports
  • Water resource planning and management.

This basin sweep covers an area generally in the southeastern portion of the state and extends east of Florence and Tucson, west of Safford, north of Benson and south of Globe-Miami. 

For more information regarding the planned basin sweep, see ADWR Public Information Officer Shauna Evans at smevans@azwater.gov or (602) 771-8079. Details about the nature of basin sweeps and groundwater modeling can be found here.


David Snider, long-time Pinal County leader on water issues, unexpectedly passes away

David Snider

David Snider, whose work on water issues for his constituents in Pinal County earned him the respect and admiration of water-community leaders throughout the state, passed away early January 22 following emergency surgery.

A member of the Pinal County Board of Supervisors for two terms, Mr. Snider also was a long-standing member of the Pinal Active Management Area Groundwater Users Advisory Council.

Groundwater user advisory councils were created as part of the landmark 1980 Groundwater Management Act. There are five such councils statewide – one in each of Arizona’s five Active Management Areas.

As gubernatorial appointees to the Pinal AMA council, Mr. Snider and his colleagues on the five-member council provided advice and recommendations on the groundwater management programs and policies within the AMA. Appointed to the GUAC in 2006, Mr. Snider during that time served as both vice-chair and chair of the council.

Mr. Snider was a long-standing member of the Pinal Active Management Area Groundwater Users Advisory Council.

Mr. Snider’s involvement in Pinal-area water issues was extensive.

He served for a time on the Local Drought Impact Group in Pinal County. LDIGs are county-level groups that coordinate drought public awareness, provide impact assessment information to local and state leaders, and implement and initiate local mitigation and response options.

In addition, he also served on the Pinal County Water Augmentation Authority, a group dedicated to supporting the development of responsible, collaborative, and sustainable water planning and management in the Pinal AMA.

Mr. Snider’s dedication to his Pinal County community extended well beyond his work on water-related issues.

The City of Casa Grande library director for 26 years, also served for many years on the Casa Grande Elementary School District Governing Board in addition to his service as a county supervisor.
