Explore Groundwater Level Changes in Arizona Sub-Basins

The Kyl Center for Water Policy developed this tool to show groundwater level changes across the state's sub-basins for 1-year (2017-18), 10-year (2008-18), and 20-year (1998-2018) time periods. The data for these features come primarily from the Arizona Department of Water Resources' Statewide Groundwater Level Changes report. Well point locations are symbolized by water level change and depth to water and include hyperlinks to site-specific well information and hydrographs. Factors to consider when thinking about the health of a basin include geology, depth to water, land subsidence, and depth to bedrock.
