Edwards BFZ Aquifer (Barton Springs segment)Alternative Groundwater Flow ModelThis map shows the extent and location of the Barton Springs segment of the Edwards (Balcones Fault Zone) Aquifer Alternative Model.

In 2011, the Texas Water Development Board (TWDB) completed the recalibration of The Barton Springs segment of the Edwards (Balcones Fault Zone) Aquifer Groundwater Availability Model, following a request by Groundwater Management Area 10 to evaluate pumping that would result in specified spring flows, at Barton Springs, of 11, 9, 7, 5, 3 cubic-feet per second under drought-of-record conditions.
