The final version of ADWR’s new  - Statewide Hydrologic Monitoring Report – and supplemental sub-basin water level change map book are now available to download. The report provides data and analysis of Arizona’s groundwater conditions over the last two decades. The period analyzed includes a time of significant variability in groundwater use trends, both inside and outside Arizona’s Active Management Areas (AMAs), and covers the first 20 years of Central Arizona Project (CAP) water deliveries for direct use and recharge in central Arizona. The last 20 years also includes an extended drought period that has affected groundwater and surface water resources throughout the state.

The report provides insight into the effectiveness of major water management strategies and programs, and also into the impacts of extended groundwater overdraft. The analysis presented also attempts, where possible, to identify the effects of drought on local groundwater conditions. The report appendix contains information on ADWR’s hydrologic data collection program and a discussion of current and future directions in ADWR’s data collection activities.
