About This Publication
This map encompasses major impoundments of the Colorado River and includes the western urban edges of Austin and extensive suburban areas interspersed with undeveloped land.  The map area is underlain by Cretaceous bedrock units that are displaced by normal faults composing the Balcones Fault Zone.  Local Quaternary alluvial deposits cover bedrock at various topographic levels.  The Balcones Escarpment extends across the southeastern corner of the map area and separates complex faulted terrain to the east from the Hill Country and dissected remnants of the Edwards Plateau to the west.  In addition to showing surface-water resources provided by the lakes, the map area also depicts important groundwater resources, including Barton Springs and part of the recharge zone and upstream contributing watersheds that feed the springs.  North of the Colorado River, extensive plateau uplands recharge the northern Edwards aquifer.  In summary, this map presents geologic information pertinent to engineering, environmental, and resource issues related to rapid population growth west of Austin.
