Aquifer Data & Maps

The EAA collects a significant amount of data each year, maintains active research and GIS mapping programs, and provides real-time data for stakeholders, scientists, educators, and members of the community. Data consists of quality chemical analysis, groundwater levels and precipitation, groundwater recharge, discharge, and use. Additional data includes evapotranspiration measurements and stream flows. Reports are published and available for review in the Technical Reports document library in this section.  Additionally, up-to-date readings and historical data can be accessed here. Understanding how the aquifer works is essential to properly manage, enhance, and protect the Edwards Aquifer system.
