Major aquifers, well yields, estimated natural recharge, number of index wells and date of last water-level sweep are shown in Table 8.1-6. Figure 8.1-6 shows aquifer flow direction and water-level change between 1991-1992 and 2002- 2003 for the entire Phoenix AMA.
Major aquifers, well yields, estimated natural recharge, estimated water in storage, number of index wells and date of last water-level sweep are shown in Table 2.1-6. Figure 2.1-7 shows aquifer boundaries, aquifer flow direction and water-level change between 1990-1991 and 2003-2004.
The first numerical groundwater flow model of the Pinal AMA was developed by the Arizona Department of Water Resources (ADWR) in 1990. This report documents an extensive update of the 1990 model.

As a result of high growth rates, physically and legally limited water supplies, drought, economic constraints and relatively little comprehensive water resource planning and management, water supplies are stressed in some parts of Arizona. The Arizona Department of Water Resources has collected and synthesized currently available water-related information for the State of Arizona into a “water atlas”, organized by planning area.
The process of updating the Pinal model geology was begun in 2007, and had not been addressed since Modeling Report No. 2 (Corkhill and Hill, 1990). The purpose of this provisional report is to document the data collection activities and findings of the hydrogeologic framework of the study area. This report will be finalized after the Pinal Active Management Area (AMA) Regional Groundwater Flow Model report which documents the update and recalibration of the groundwater flow model in Pinal County have been completed.
Managing regional aquifer systems within the arid southwestern U.S. basins requires an understanding of the extent to which aquifer recharge and withdrawal impacts the systems, both spatially and temporally.
The Assured and Adequate Water Supply Rules require applicants to submit hydrologic information to support certain aspects of their applications.
Section I of the Third Management Plan provides an overview of the Arizona Department of Water Resources' (Department) water management approach, a description of the physiologic and hydrologic conditions, and water resources of the Phoenix Active Management Area (AMA), and a detailed description of water use characteristics of the various water use sectors within the AMA.
