Nacatoch Aquifer Groundwater Availability Model (GAM)

This map shows the extent and location of the southern portion of the Nacatoch Aquifer GAM.In 2006, the Texas Water Development Board contracted with LBG-Guyton & Associates (who teamed with INTERA, Inc. and Dr. Graham Fogg) to develop a Groundwater Availability Model for the Nacatoch Aquifer. The project was completed and delivered in 2009.

In 2021, TWDB scientists commenced work on the update for the Nacatoch Aquifer GAM.
