The Gulf Coast Aquifer SystemGroundwater Availability Model (GAM) for groundwater management areas 15 and 16This map shows the extent and location of the southern portion of the Gulf Coast Aquifer System Groundwater Availability Model.

The Texas Water Development Board is developing a groundwater availability model of the Gulf Coast Aquifer System in groundwater management areas 15 and 16. The model is expected to be completed no earlier than at the end of August, 2021.
