  1. Groundwater Management Area 7

  2. GAM 7-32 • Change in water levels in the Edwards layer if current pumping is extended over 50 years under normal rainfall conditions

  3. GAM 7-37 • Change in water levels over 50 years in the Edwards layer of the Edwards-Trinity aquifer projecting current pumping under drought of record conditions

  4. Minor Aquifers of GMA 7

  5. Section 36.108 of the Texas Water Code Requires GCDs in a GMA to submit DFC’s to the TWDB, which uses a GAM to determine MAGs!

  6. GROUNDWATER AVAILABILITY MODELS Computer models which simulate the operation of aquifers when various inputs are changed

  7. MANAGED AVAILABLE GROUNDWATER (MAG) • The amount of water: • available for permitted production in an aquifer • which will implement the attainment or maintenance of the Desired Future Condition
