Water developments are a widely used wildlife management tool in the arid Southwest. The ecological effects of those facilities have received little study and remain a source of controversy. We studied direct and indirect effects of wildlife water developments in southwestern Arizona from 1999-2003. Our results did not support hypothesized negative impacts suggested by critics of wildlife water development programs.

On March 20, 2003, Governor Janet Napolitano established the Governor’s Drought Task Force to address the drought issues facing all Arizonans. The Task Force made several recommendations, documented in the "Arizona Drought Preparedness Plan", including that the Governor seek legislative authority for the Arizona Department of Water Resources to require water systems to develop a drought plan. The plan would include mitigation strategies, including a water conservation plan to reduce vulnerability to drought and plan for drought response actions. In addition, the Governor’s Drought Task Force recommended legislative authorization for ADWR to require all water systems to provide consistent and coordinated water supply information to ADWR. The Arizona Legislature passed House Bill 2277 during the 2005 legislative session, creating a requirement for community water systems to develop and submit a System Water Plan to ADWR. The development of these plans is an important step toward improving water resource management planning at both the state and local levels. They will enable the state to identify data gaps and gather much needed information.

In 2001, ADWR undertook a review of the Upper San Pedro Basin to determine if it met the statutory requirements for designation as an AMA. This report reviews the water supply and demand of the USP Basin in the context of the statutory criteria and includes a discussion of whether any of the criteria have been met. Previously, ADWR conducted a study of the USP Basin and issued a report in 1988 in which ADWR determined that the Basin did not meet the statutory criteria for AMA designation. ADWR indicated in the report that it would reassess conditions in the Basin in ten to fifteen years. The study described in this report is an evaluation of whether the conditions of the USP Basin satisfy the statutory criteria. 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. 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.
