Explore groundwater level changes in Arizona sub-basins

Groundwater is a critical resource in Arizona, and changes in demand for groundwater have given rise to growing concern about the long-term resilience of some of the state’s aquifers.

The Kyl Center for Water Policy’s new Arizona Groundwater Level Change App shows what’s happening in sub-basins across the state – where groundwater levels are rising or declining and where more data may be needed.

The data for this powerful new tool are derived from the Arizona Department of Water Resources’ Statewide Groundwater Level Changes report (Open-File Report No.18, December 2020).
