GAM's Mission:

to provide reliable, timely data on groundwater availability to the citizens of Texas to ensure adequacy of supplies or recognition of inadequacy of supplies throughout the 50 year planning horizon.

GAM will result in publicly available numerical groundwater flow models for the major and minor aquifers of Texas.
