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. Groundwater also supplies about 35 percent of the states municipal needs. The largest area of groundwater-level decline in the Ogallala aquifer was found in Gaines County to the southwest of Denver City, Texas. The Carrizo-Wilcox Aquifer has long been utilized by private well owners, municipalities, agricultural producers and industry. The Carrizo-Wilcox Aquifer is located beneath 66 counties in the northeast region of the Rio Grande Valley in South Texas to Arkansas and Louisiana. (Note that the National Aquifer Code uses a different numeric component than the geohydrologic unit names.). Irrigation was the principal use in Medina and Uvalde counties. We are the premier source for trusted information about Texas. In 2008, about 72 percent of pumpage from the aquifer was for municipal use. Click any position on the map to reveal attributes for a specific location. We'd love to hear from you. The aquifer consists of sand, gravel, clay, and silt and has a maximum thickness of 800 feet. The surface extent, or outcrop, of each aquifer is the area in which the host formations are exposed at the land surface.

Water in the aquifer occurs in fractures, honeycomb zones (or intergranular pores), and solution channels in the Edwards and associated limestone formations of Cretaceous age. The Trinity Aquifer consists of basal Cretaceous-age Trinity Group formations extending through 61 counties from the Red River in North Texas to the Hill Country of Central Texas. In scattered places in the United States, carbonate rocks are interbedded with almost equal amounts of water-yielding sandstone. Water level increases were found in the northern portion of the study area, near the Yoakum and Terry County boundary and in northeastern Gaines County. Aquifers are identified by a geohydrologic unit code - a three-digit number related to the age of the formation, followed by a 4 or 5 character abbreviation for the geologic unit or aquifer name. And so we've seen water levels drop in those aquifers and we've seen spring flows as a response also drop. The aquifer is primarily composed of sand locally interbedded with gravel, silt, clay, and lignite. Located in the upper Pecos River Valley of West Texas, this aquifer, formerly called the Cenozoic Pecos Alluvium, extends through 12 counties. Years of heavy pumpage have caused significant water-level declines in portions of the aquifer. 1700 North Congress Avenue, Austin, TX 78701TEL: 512-463-7847 / FAX: 512-475-2053, Asset Management

Secure .gov websites use HTTPS In 2019, more than 4.4 million acre-feet were pumped from the Ogallala Aquifer, accounting for 67 percent of the water sourced from all major Texas aquifers. Water to the north of the Canadian River is generally fresh, with total dissolved solids typically less than 400 milligrams per liter. Page Contact Information: Texas Water Data Maintainer Page Last Modified: 2023-02-25 01:14:50 EST The aquifer is one of the most extensive and highly used groundwater resources in Texas. It is the third most important groundwater resource in Texas after the Edwards and the Ogallala aquifers. Delineations of the downdip boundaries of such aquifers as the Edwards (BFZ), Trinity, and Carrizo-Wilcox are based on chemical quality criteria. These aquifers are located in El Paso and Hudspeth counties in far West Texas and occur in Tertiary and Quaternary basin-fill deposits that extend northward into New Mexico and westward into Mexico. Tell us about it! The groundwater information summarized in the Atlas was collected over many years by the USGS and other partner agencies,andprovides key descriptive information in a regional and national context. Water from the Antlers portion is used mainly for irrigation in the outcrop area of North and Central Texas. Aquifers are vital to the states economy and environment, highlighting the need for their proper management and conservation. Until recently, San Antonio was one of the largest cities in the world that relied solely on a single groundwater source for its municipal supply. Footer Social Media Navigation In 2008, irrigation accounted for 43 percent of water pumped from the aquifer, and municipal supply accounted for 47 percent. The Gulf Coast aquifer forms an irregularly shaped belt that parallels the Texas coastline and extends through 54 counties from the Rio Grande northeastward to the Louisiana border. This system has been divided into three major water-producing components referred to as the Chicot, Evangeline, and Jasper aquifers. The Texas Water Development Board (TWDB) has identified and characterized nine major and 20 minor aquifers in the state based on the quantity of water supplied by each.

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. The Texas Water Development Board (TWDB) recognizes 9 major aquifers aquifers that produce large amounts of water over large areas (see major aquifers map) and 22 minor aquifers aquifers that produce minor amounts of water over large areas or large amounts of water over small areas (see minor aquifers map ). The competition for ground water from the Edwards aquifer has created some controversial water issues in central Texas. It consists of sandstone and limestone formations of the Trinity formations, and limestones and dolomites of the Edwards and associated limestone formations. Search and browse the first 148 years of the Texas Almanac, hosted on the UNT Portal to Texas History. Aquifers are identified by a geohydrologic unit code-a three-digit number related to the age of the formation, followed by a 4 or 5 character abbreviation for the geologic unit or aquifer name. Irrigation accounts for more than half of the aquifer's discharge. Select the area, distance or location tool below. 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. They are grouped into four categories: basin-fill, blanket sand and gravel, glacial-deposit, and stream-valley aquifers. El Paso, however, has reduced its use of groundwater from the Hueco Bolson since 1989, and observation wells indicate that water levels have stabilized. The Wilcox Group and overlying Carrizo Sand form a hydrologically connected system of sand locally interbedded with clay, silt, lignite, and gravel. Irrigation, mainly in the northwestern portion of the region, accounted for about 79 percent of total aquifer use in 2008 and has resulted in significant water-level declines in Glasscock and Reagan counties.
