• Upper San Pedro Basin Active Management Area Review Report

  Arizona Department of Water Resources - March 2005.
  ( 219 pages. 26, 932 k.b. pdf)
  
  “The study described in this report is an evaluation of whether the conditions of the Upper San Pedro Basin satisfy the statutory criteria of an Active Management Area. This report contains a description of the current and projected water resources and water demand in the Basin, incorporating new information since the previous review in 1988. The report examines historic water use trends, evaluates the groundwater resources of the Basin, and projects impacts of future water use on Basin groundwater supplies. The report includes an evaluation of the incidence of subsidence or fissuring, and of the potential for groundwater quality degradation due to groundwater use. The report further describes and evaluates the impact that AMA practices would have on water use, and includes a summary of findings, the director’s determination of whether the Basin should be designated and recommendations”

• Water Atlas Volume III – Southeastern Arizona Planning Area

  Arizona Department of Water Resources – November, 2006 (54 pages)
  
  Volume 3 – a comprehensive review of the Department of Water Resources of water supply and demand conditions. The Atlas is data-focused, consisting primarily of maps, tables, figures and concise text. The purpose is to assist local and regional planning efforts; identify water resource issues facing rural AZ communities; compile recent information and update prior statewide water assessments; identify areas requiring further study; and, develop and maintain an online rural AZ database. Volume I-Introduction is a companion report to each of the other volumes. Volume IX is an Executive Summary not yet published.

• Hydrogeologic Investigation of the Middle San Pedro Watershed, Southeastern Arizona: A Project of the Rural Watershed Initiative

  2006 - 2012
  
  Seven-year study currently underway with data collection and analysis by the United States Geological Survey and Arizona Department of Water Resources. Primary objective is to improve the understanding of the hydrogeology of the Middle San Pedro Subwatershed. Specific Objectives are to:

  • Assess the current state of knowledge of the ground-water system
  • Describe and quantify the hydrogeologic framework
  • Describe and quantify the ground-water flow system, including recharge, discharge, water in storage, and historical changes in the system
  • Construct a predictive numerical model of the ground-water system that can be used to help guide decisions by planners and water managers about future development.

  Nonpoint Education for Municipal Officials, UofA Cooperative Extensions, 2007
  
  Plan includes a watershed characterization, watershed classification, and discussion of recommended nonpoint source Best Management Practices that may be implemented to achieve pollutant load reductions and other watershed goals. “The watershed characterization includes physical, biological, and social/economic data in a geographic information system database format, as both mapped and tabulated data, that has been collected from available existing and published data sources. (No new field data were collected for this plan). The watershed classification includes the identification and mapping of important resources and ranking of subwatersheds based on the likelihood of nonpoint source pollutant contribution to stream water quality degradation”.

• Arizona Department of Environmental Quality

  The agency's Water Quality Division is responsible for the carrying out the mandates of the Arizona Environmental Quality Act (EQA) and the federal Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). These regulations require the State to establish water quality standards for aquifers and surface waters, conduct water quality monitoring and assessments, develop total maximum daily load studies on impaired waterbodies and to develop watershed plans, with local stakeholders, aimed at improving water quality through both permitted and voluntary programs.

• Arizona Dept Water Resources

  “The Arizona Department of Water Resources works to secure long-term dependable water supplies for Arizona's communities. The Department administers and enforces Arizona’s groundwater code, and surface water rights laws (except those related to water quality); negotiates with external political entities to protect Arizona's Colorado River water supply; oversees the use of surface and groundwater resources under state jurisdiction; and represents Arizona in discussions of water rights with the federal government. In addition, the Department explores methods of augmenting water supplies to meet future demands, and develops policies that promote conservation and equitable distribution of water.”
