Edwards Aquifer Map


The Edwards Aquifer is a unique groundwater system and one of the most prolific artesian aquifers in the world. It is one of the greatest natural resources on Earth, serving the diverse agricultural, industrial, recreational, and domestic needs of almost two million users in south central Texas.

The Barton Springs/Edwards Aquifer Conservation District is committed to conserving, protecting, recharging, and preventing waste of groundwater and preserving all aquifers in the District. The Barton Springs/Edwards Aquifer Conservation District was created in 1987 with a directive to conserve, protect, and enhance the groundwater resources in.

Edwards aquifer map. The Edwards Aquifer is a large aquifer, located in central/southern Texas. It covers an area of 4,350 square miles. The Edwards Aquifer has served and continues to serve central/southern Texas. Its uses have ranged from recreation to drinking water, and industry. This aquifer also faces environmental pressures. Edwards aquifer, the Edwards aquifer, the upper zone of the Trinity aquifer, and the middle zone of the Trinity aquifer. The Pecan Gap Formation (Taylor Group), Austin Group, Eagle Ford Group, Buda Limestone, and Del Rio Clay are generally considered to be the upper confining unit to the Edwards aquifer. The map, which is derived from the Ground Water Atlas of the United States, indicates the areal extent of the uppermost principal aquifers on a national scale. In this map, a principal aquifer is defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a source of potable water.

The Edwards aquifer in south-central Texas is one of the most productive aquifers in the Nation and is the primary source of water for the rapidly growing San Antonio area. Springs issuing from the Edwards aquifer provide habitat for several threatened and endangered species, serve as locations for recreational activities, and supply downstream.

It is part of a much larger system that spans approximately 8,800 square miles. The Edwards Aquifer Authority manages the San Antonio segment of the Balcones Fault … Continue reading "Maps"

Edwards Aquifer Viewer. version 4.1. Skip to Header Controller; Skip to Map. Describes regulatory boundaries of Edwards Aquifer Recharge Zone based on the adoption of the Texas Commission on Environmental Quality (TCEQ) Recharge Zone Boundary, defined in September of 2005. The recharge zone is a 1,250 square mile area where highly faulted and fractured Edwards limestones outcrop at the land surface, allowing large quantities of water to flow into the Aquifer. For this reason, the Edwards is often called a fault-zone aquifer (see section on Faults & Caves for fault map and photos).

The Edwards (Balcones Fault Zone) Aquifer is a major aquifer in the southcentral part of the state. It consists primarily of partially dissolved limestone that creates a highly permeable aquifer. Aquifer thickness ranges from 200 to 600 feet, and freshwater saturated thickness averages 560 feet in the southern part of the aquifer. Current Edwards Aquifer Level: 0 ' 2020 Statistic Summary.

The Edwards Aquifer maps come from official printed maps, containing regulatory boundaries based on previous geologic interpretations of the Edwards Aquifer zones—that is, the recharge, transition, and contributing within the transition zones, as defined in 30 TAC 213. The Edwards-Trinity (Plateau) Aquifer is a major aquifer extending across much of the southwestern part of the state. The water-bearing units are composed predominantly of limestone and dolomite of the Edwards Group and sands of the Trinity Group. The Edwards Aquifer Authority is a groundwater district, mandated by the 1993 Edwards Aquifer Authority Act. The Act grants all of the powers, rights, and privileges necessary to manage, conserve, preserve, and protect the aquifer.

The Edwards Aquifer is one of the most prolific artesian aquifers in the world. Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer's region.In addition, the Edwards Aquifer feeds the Comal and San Marcos springs, provides springflow. Edwards-Trinity (High Plains) Aquifer Quick Facts. Minor aquifer that underlies southern and eastern counties in the HPWD. Recharge to the aquifer is primarily due to downward leakage from the younger Ogallala Aquifer. Freshwater saturated thickness in the aquifer averages 126 feet. Water quality is generally slightly saline
