Delineations of the downdip boundaries of such aquifers as the Edwards (BFZ), Trinity, and Carrizo-Wilcox are based on chemical quality criteria. Aquifers shown on the 2003PrincipalAquifers map, with some additions, were used as the first National AquiferReferenceList in the USGSNational Water Information System(NWIS) in theAggregate Water Use Data System(AWUDS,database released in August 2001). storage and recovery facility The characterization of the state's groundwater resources and the development of the maps depicting these aquifers have been accomplished by many staff members of the TWDB over many years. Extensive development of the Trinity Aquifer in the Dallas-Fort Worth and Waco areas has resulted in water-level declines of 350 to more than 1,000 feet. A .gov website belongs to an official government organization in the United States. There are 13 major and 20 minor aquifers; in the Hill Country, the major aquifers are the Edwards and the three water-producing zones of the Trinity. We'd love to hear from you.

Although referred to differently in different parts of the state, they include the Antlers, Glen Rose, Paluxy, Twin Mountains, Travis Peak, Hensell, and Hosston aquifers. Aquifers play a major role in providing water to many parts of Texas. Water quality generally ranges from fresh to slightly saline. A poorly defined groundwater divide in Hays County hydrologically separates the aquifer into the San Antonio and Austin regions. In 2005,thenational aquiferinformationwas addedto NWIS, allowing users to search by national aquifer code and name from the reference list below. There are nine major aquifers and 22 minor aquifers that supply groundwater for municipal and irrigation needs throughout the state. In general, groundwater is fresh but very hard in the outcrop of the aquifer.

Texas Water Development Board. New and Environmentally Improved. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. Revisions to the reference list since it was first used by NWIS: Northern Great Plains aquifer system was removed:this umbrella term includes four national aquifers but is not considered a national aquifer itself. It consists of the Hooper, Simsboro, and Calvert Bluff formations of the Wilcox Group and the overlying Carrizo Formation of the Claiborne Group. He got the county through the crisis, and thanks to some heavy rains in 2012, the aquifer rebounded a little. Near the plateaus edge, flow is toward the main streams, where the water issues from springs. Some of the state's largest water level declines, ranging from 350 to more than 1,000 feet, have occurred in counties along the IH-35 corridor from McLennan County to Grayson County. Refer to the metadata for a complete description of the files and how they were generated. The Trinity Aquifer is a major aquifer that extends across much of the central and northeastern part of the state.

Municpal water use in 2008 accounted for 87 percent of total use from the Hueco-Mesilla Bolson. Click any position on the map to reveal attributes for a specific location.

The aquifer maps and reports undergo continual revision to reflect the latest information available. The pages below contain descriptionsand maps of these main aquifer types: These pages, formerly hosted at ourAquifer Basicswebsite,provide ageneral summary of information published in the Ground Water Atlas of the United States. Sulfate and chloride concentrations also tend to increase with depth. A two-dimensional map representation of the principal aquifers of the Nation is shown below. Page Contact Information: Texas Water Data Maintainer Page Last Modified: 2023-02-25 01:14:50 EST However, because these aquifers extend over large areas, large volumes of water can be withdrawn. Volcanic-rock aquifers have a wide range of chemical, mineralogic, structural, and hydraulic properties Aquifer maps often include large-to-small areas that are designated "minor aquifer," "not a principal aquifer," or "confining unit. These are usually areas are underlain by low-permeability deposits and rocks, unsaturated materials, or aquifers that supply little water because they are of local extent, poorly permeable, or both. Computer models of the northern and southern portions of the Ogallala aquifer were completed by the Texas Water Development Board and its contractor. The lower, more permeable part of the aquifer produces the greatest amount of groundwater. Irrigation was the principal use in Medina and Uvalde counties. ASR is the process of capturing water from heavy rainfall and injecting it into underground water wells where it is stored for later use. Water levels in several counties in this region are very low due to over-pumping. Aquifers in carbonate rocks are most extensive in the eastern U.S. Groundwater movement is generally toward the southeast. Declines continue in Ward County due to increased municipal and industrial pumping.
