Researchers have identified a previously undiscovered aquifer in southwest Texas. In general, groundwater is fresh but very hard in the outcrop of the aquifer. The Texas Water Development Board recognizes and names 15 such aquifers. This map, which was derived fromGround Water Atlas of the United Statesdata (published as part of the National Atlas in 1998, revised 2003) indicates the areal extent of the uppermost principal aquifers on a national scale. The Ogallala Aquifer is the largest aquifer in the United States and is a major aquifer of Texas underlying much of the High Plains region. Larry French, director of the groundwater division at the Texas Water Development Board, spoke to Texas Standard about its potential .

The Hueco Bolson, located on the eastern side of the Franklin Mountains, consists of up to 9,000 feet of clay, silt, sand, and gravel and is an important source of drinking water for both El Paso and Juarez, Mexico. 1, Management plan information for Gateway GCD, Predictive simulations for the Ogallala and Edwards-Trinity (High Plains) aquifers in Groundwater Management Area 7, Predictive simulation for the Ogallala and Edwards-Trinity (High Plains) aquifers in Groundwater Management Area 2, Management plan information for Llano Estacado UWCD, Management plan information for Garza County UWCD, Management plan information for Sandy Land UWCD, Predictive simulations for the Ogallala Aquifer in Groundwater Management Area 1, Predictive simulations for the Ogallala Aquifer in Groundwater Management Area2, Initial and final water volumes for the simulations presented in GAM Run 08-085, Predictive simulation for the Ogallala Aquifer in Groundwater Management Area 2, Management plan information for Garza County Underground and FWCD, Management plan information for Mesa UWCD, Management plan information for Permian Basin UWCD, Management plan information for Panhandle GCD, Management plan information for Glasscock GCD, Management plan information for South Plains UWCD, Predictive simulations for the Ogallala Aquifer in Groundwater Management Area 2, Volume calculations for the Ogallala Aquifer in Groundwater Management Area 1, Volume calculations and pump rates for the Ogallala Aquifer in Groundwater Management Area 1, Analysis using specified depletions for districts in Groundwater Management Area 1, Management plan information for North Plains GCD, Water budget and GIS information for the Ogallala Aquifer in Hemphill County, Saturated thickness shapefile for the Ogallala Aquifer in Hemphill County, Saturated thickness shapefile for the Ogallala Aquifer in Hemphill County (zip file), Saturated thickness maps for the Ogallala Aquifer in Region A, Groundwater volumes for the Ogallala Aquifer in Randall and Oldham counties, Comparison of groundwater volumes between GR 04-13 and GR 05-09 for the Ogallala Aquifer in Region A, Saturated thickness, groundwater volumes, and water level maps for the Ogallala Aquifer in Region A, Various pumping scenarios for the Ogallala Aquifer in Hemphill County, Water budget and volume of water in storage for Hemphill County using a predictive simulation, Saturated thickness map for the Ogallala (north) Aquifer, Recharge rates per model cell in the Ogallala (north) Aquifer GAM, Groundwater in storage for Region A using a 1.25% annual depletion rate, Hydraulic conductivity data for the Ogallala Aquifer GAMs, Volumetric calculations for all counties in Llano Estacado Regional Water Planning Group, Groundwater volume in each county-basin zone of Region O (Llano Estacado), Determine pumping rate equivalent to a volume depletion rate of no more than 1% per year, Predictive run with Region O provided increase in irrigation pumping, Water table declines and water budget in South Plains UWCD, Groundwater volume in each county-basin zone of Region O (Llano Estacado) Clarification memo, Water budget and total available storage for the Ogallala Aquifer in Permian Basin UWCD, Volume of water in storage and recharge information for the Ogallala Aquifer in High Plains UWCD No. Groundwater movement is generally toward the southeast. In most places where these two rock types are interbedded, the carbonate rocks yield much more water than the sandstone. Groundwater also supplies about 35 percent of the municipal needs of the state. Aquifers can contain fresh, brackish, or saline water; or, usually, all three There are several types of aquifers with very different characteristics Michael Conner: Understanding Aquifers 7 All the "science" about aquifers is a simplification, and it is frequently quite controversial.

The aquifer also feeds several well-known recreational springs and underlies some of Texas most environmentally sensitive areas. The availability of this water is critical to the economy of the region, as approximately 95 percent of groundwater pumped is used for irrigated agriculture. Barton SpringsEdwards Aquifer Conservation District provides aquifer management for the rest of Hays and southern Travis counties, and the Kinney County Groundwater Conservation District manages the aquifer segment within Kinney County.

Find out the correct way to pronounce Mexiaalong with hundreds of other places all across Texasby downloading our helpful Pronunciation Guide The appropriate component aquifer should be used instead of Northern Great Plains. 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). Get your free copy of the 20202021 Texas Almanac eBook. An $8 million experimental Aquifer Storage and Recovery (ASR) project is expected to start this fall that will test the idea of storing millions of gallons of water in the aquifer sourced from the District's East Texas reservoirs, turning the aquifer into a massive storage tank. A .gov website belongs to an official government organization in the United States. Water-level declines are occurring in part of the region because of extensive pumping that far exceeds recharge. This list of national principal aquifer codes and names are fixed values assigned by the National Water Information System (NWIS). Below are publications associated with national aquifers. These declines are primarily attributed to municipal pumping, but they have slowed over the past decade as a result of increasing reliance on surface water.

The Ogallala Aquifer is the largest aquifer in the United States and is a major aquifer of Texas underlying much of the High Plains region. The map layer was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series Ground Water Atlas of the United States. National Geographic Information Systems (GIS) layer of SSAs Information on sole source aquifers (SSAs) is widely used in assessments under the National Environmental Policy Act and at the state and local level. Although the Carrizo-Wilcox Aquifer reaches 3,000 feet in thickness, the freshwater saturated thickness of the sands averages 670 feet. PrefaceThe Ground Water Atlas of the United States presents a comprehensive summary of the Nation's ground-water resources and is a basic reference for the location, geography, geology, and hydrologic characteristics of the major aquifers in the Nation. The aquifer now provides approximately 90 percent of the citys drinking water. Irrigation pumpage accounted for 94 percent of the total use from the aquifer in 2008. Several agencies are investigating playa recharge and agricultural re-use projects over the aquifer. Water quality in the Carrizo-Wilcox Aquifer shows isolated areas of slightly saline to moderately saline groundwater in the eastern and central portions of the aquifer and more widespread areas of slightly to moderately saline groundwater in the southwest. To learn more, visit theNational Aquifer Code Reference List. He got the county through the crisis, and thanks to some heavy rains in 2012, the aquifer rebounded a little. Eastward-flowing streams during the Quaternary Period deposited discontinuous beds of poorly sorted gravel, sand, silt, and clay that were later dissected by erosion, resulting in the isolated remnants of the formation. These aquifers consist of limestones, sands, clays, gravels, and conglomerates. The areal and vertical location of major aquifers is fundamental to the determination of groundwater availability for the Nation. A poorly defined groundwater divide in Hays County hydrologically separates the aquifer into the San Antonio and Austin regions. 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. Additional aquifer data through the USGS web app Irrigation pumping accounts for slightly more than half the water pumped, and pumping for municipal supply accounts for another 40 percent. Their combined freshwater saturated thickness averages about 600 feet in North Texas and about 1,900 feet in Central Texas. Share sensitive information only on official, secure websites. A two-dimensionalmap representation of the principal aquiferswas derived from this data and published as part of the National Atlas in 1998 (revised 2003). Water-conservation measures by agricultural and municipal users are being promoted. Water levels in several counties in this region are very low due to over-pumping. County State Well Number Aquifer Aquifer Type Entity/Cooperator Period of Record Wheeler : 0529711 : Ogallala : Unconfined : Texas Water Development Board 2006-07-18 to 2012-08-15: Carson . Consisting of up to 1,500 feet of alluvial fill, the aquifer occupies two hydrologically separate basins: the Pecos Trough in the west and the Monument Draw Trough in the east. storage and recovery facility You may need to request the addition of Alluvial aquifers to the list of aquifers valid in your State. 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. It consists of the Hooper, Simsboro, and Calvert Bluff formations of the Wilcox Group and the overlying Carrizo Formation of the Claiborne Group. Computer models of the northern and southern portions of the Ogallala aquifer were completed by the Texas Water Development Board and its contractor. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. (February 2005), Valley and Ridge carbonate-rock aquifers were removed:these now should be included in Valley and Ridge aquifers. An official website of the United States government.

However, because these aquifers extend over large areas, large volumes of water can be withdrawn. 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.

Center the map where you want the center of your print, enter a title in the textbox and choose a page size for your print using the drop down. Aquifers play a major role in providing water to many parts of Texas. And so we've seen water levels drop in those aquifers and we've seen spring flows as a response also drop. The desired future conditions provide the foundation for estimating the amount of groundwater available to the region. the largest aquifer In cooperation with Harris-Galveston Subsidence District, the
