The Arizona Department of Water Resources is the State agency responsible for managing and allocating the State's groundwater supplies.  This is accomplished through data collection, data management, and data analysis, resulting in groundwater policies and management for the entire State, including Active Management Areas and rural groundwater basins.

ADWR has developed interactive maps and a simple search wizard of the Department's entire Groundwater Site Inventory database (GWSI) and Wells Registry database (Wells55) including automated sites and index wells. The interactive map can be used to identify groundwater levels and well information as well as to create custom hydrographs and locate wells around the State.
