Adopt the TX Town or County of your choice and share your message with the world. Extending from the Rio Grande in South Texas northeastward into Arkansas and Louisiana, the Carrizo-Wilcox aquifer provides water to all or parts of 66 counties. About 60 percent of the approximately 16 million acre-feet of water used yearly in Texas is derived from underground formations that make up 9 major and 22 minor aquifers. This aquifer underlies the Edwards Plateau, extending through 40 counties from the Hill Country of Central Texas westward to the Trans-Pecos region. The Ogallala aquifer extends through 48 counties of the Texas Panhandle and is the southernmost extension of the largest aquifer (High Plains aquifer) in North America. Presented by The Catahoula Aquifer is considered an Alternative Water Source (AWS) in Montgomery County. Declines continue in Ward County due to increased municipal and industrial pumping. (March 2005). We are the premier source for trusted information about Texas. In 2008, 72 percent of groundwater pumped from the aquifer was used for irrigation, and the rest is withdrawn for industrial uses, power supply, and municipal use. However, because these aquifers extend over large areas, large volumes of water can be withdrawn. The Texas Water Development Board recognizes and names 15 such aquifers. This dataset, published in 2003, contains the shallowest principal aquifers of the conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, portrayed as polygons.

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 aquifer system is composed of the Catahoula, Oakville, Fleming, Goliad, Willis, Lissie, Bentley, Montgomery, and Beaumont formations. Individual accumulations vary greatly in thickness, but most of the Seymour is less than 100 feet. The Maverick Aquifer, as it's been named, lies more than a mile deep under parts of Maverick, Uvalde, Dimmit and Kinney Counties. 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). Please note that the maps do not show the entire extent of an aquifer, only itssubcropor outcrop area. Local aquifer: Not all groundwater sites have been associated with a local aquifer. Water levels in several counties in this region are very low due to over-pumping. 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. Years of heavy pumpage have caused significant water-level declines in portions of the aquifer. Aquifers are shown in the States of Maine, Vermont, New Hampshire, Connecticut, Massachusetts, Rhode Island, New Jersey, New York, Pennsylvania, Ohio, Indiana, Michigan, Wisconsin, Illinois, Minnesota, Iowa, Missouri, Kansas, Nebraska, South Dakota, North Dakota, and Montana. Several agencies are investigating playa recharge and agricultural re-use projects over the aquifer. Water-level declines in excess of 200 feet have occurred in Reeves and Pecos counties but have slowed since the mid-1970s with the decrease in irrigation pumpage. Researchers have identified a previously undiscovered aquifer in southwest Texas. 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. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. Irrigation pumping accounts for slightly more than half the water pumped, and pumping for municipal supply accounts for another 40 percent. Select the area, distance or location tool below. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. Last fall while exploring for oil and gas deposits in southwest Texas, a driller instead found a huge freshwater deep aquifer. 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. Footer Social Media Navigation Historically, Texas has had a wealth of fresh to slightly saline water, which underlies more than 81 percent of the state. Although the Carrizo-Wilcox Aquifer reaches 3,000 feet in thickness, the freshwater saturated thickness of the sands averages 670 feet. General Information Letters and Private Letter Rulings, State Tax Automated Research (STAR) System, Historically Underutilized Business (HUB), Vendor Performance Tracking System (VPTS), Texas Procurement and Contract Management Guide, Minnie Stevens Piper Foundation College Compendium.

These aquifers, which are in rocks that range in age from Pleistocene to Cambrian, Water quality generally ranges from fresh to slightly saline. Guadalupe runs dry with rainfall scarce. Because of the scar-city of measurable water-table wells, depth to the water table below land surface was estimated using Summary The Carrizo-Wilcox Aquifer is a major aquifer extending from the Louisiana border to the border of Mexico in a wide band adjacent to and northwest of the Gulf Coast Aquifer. The Hickory aquifer occurs in parts of 19 counties in the Llano Uplift region of Central Texas. We'd love to hear from you. The largest area of groundwater-level decline in the Ogallala aquifer was found in Gaines County to the southwest of Denver City, Texas. The competition for ground water from the Edwards aquifer has created some controversial water issues in central Texas. The San Antonio River Authority also has a number of flood-control structures that effectively recharge the aquifer. Groundwater also supplies about 35 percent of the states municipal needs. 1700 North Congress Avenue, Austin, TX 78701 TEL: 512-463-7847 / FAX: 512-475-2053. Computer models of the northern and southern portions of the Ogallala aquifer were completed by the Texas Water Development Board and its contractor. Although its primary use is for municipalities, it is also used for irrigation, livestock, and other domestic purposes. About 55 percent of all water used in Texas was sourced through aquifers in 2019. The aquifer now provides approximately 90 percent of the citys drinking water. ; Metadata - The Edwards Aquifer maps were developed from official printed maps that contain regulatory boundaries based on geologic interpretations of the Edwards Aquifer zonesthat is, the recharge, transition, and contributing within the transition zones, as . 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. Irrigation was the principal use in Medina and Uvalde counties. Groundwater in the unconfined area is hard and typically has total dissolved solids concentrations less than 1,000 milligrams per liter. Aprincipal aquiferis defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a source of potable (drinkable) water. In scattered places in the United States, carbonate rocks are interbedded with almost equal amounts of water-yielding sandstone. Texas Water Development Board works best with JavaScript enabled. In 2008, about 72 percent of pumpage from the aquifer was for municipal use. Groundwater also supplies about 35 percent of the municipal needs of the state. 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. This dataset, published in 2002, represents the extent of the alluvial and glacial aquifers north of the southern-most line of glaciation. There are nine major aquifers and 22 minor aquifers that supply groundwater for municipal and irrigation needs throughout the state. The first 62 editions of the Texas Almanac are fully searchable to aid researchers and students of Texas history. AWUDS has a graphical user interface that facilitates data entry, revision, review, and approval. An official website of the United States government.
