Beets will help keep Bexar County roads from freezing this week. Most water from aquifers is used for irrigation. The published maps contain base and cultural features not included in these data. Delineations of the downdip boundaries of such aquifers as the Edwards (BFZ), Trinity, and Carrizo-Wilcox are based on chemical quality criteria. The quality of groundwater used for public supply was assessed in 25 principal aquifers (PAs) that account for 84% of groundwater pumped for public supply in the U.S. (89.6 million people on a proportional basis). About 32 percent of water used to meet municipal demands is from groundwater. And so we've seen water levels drop in those aquifers and we've seen spring flows as a response also drop. 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. January 31, 2023. Share sensitive information only on official, secure websites. Sandstone aquifers can be highly productive and provide large volumes of water. (.pdf file). storage and recovery facility The areal and vertical location of major aquifers is fundamental to the determination of groundwater availability for the Nation. in Texas. Increased salinity may be associated with evaporative concentration of groundwater in saline playa lakes in the southern portion of the aquifer, up flow of more saline groundwater from the underlying Dockum Aquifer and other sources./p>. Researchers have identified a previously undiscovered aquifer in southwest Texas. See more information on Water Issues and the Texas economy.

Their combined freshwater saturated thickness averages about 600 feet in North Texas and about 1,900 feet in Central Texas. In Texas, a minor aquifer is defined as one that supplies large quantities of water in small areas or small quantities of water in large areas. Texas Water Development Board. 1, Management plan data for Llano Estacado UWCD, Management Plan Information for Hemphill County UWCD, Management plan information for Mesquite GCD, Management plan information for High Plains UWCD #1, Management plan information for Hemphil County UWCD, Proportion of aquifer with groundwater conservation districts: 86 percent, Number of counties containing the aquifer: 49. This system has been divided into three major water-producing components referred to as the Chicot, Evangeline, and Jasper aquifers. However, the salinity has increased in many heavily pumped areas to the point where the water has become unsuitable for domestic and municipal use. This is an important step in planning for water in Texas and Bastrop County for the next 50 years. Irrigation used the largest amount of ground water, 56,900 million gallons per day, foll, 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. It is absent in a broad area extending from the north central portion of the county continuing to the south, southwest part of Gillespie County. Water Tour | Aquifers Overview | Print Snapshot (PDF). This website compiles USGS resources and data related to principal aquifers including Aquifer Basics, principal aquifers maps and GIS data, and the National Aquifer Code Reference List. The aquifer system is composed of the Catahoula, Oakville, Fleming, Goliad, Willis, Lissie, Bentley, Montgomery, and Beaumont formations. Some of these declines have resulted in significant land-surface subsidence, particularly in the Houston-Galveston area. 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 . Does your community have an annual fair or festival you'd like to have listed on our site, or in the next Texas Almanac? The study area comprises about 2,000 square miles of out-crops of the Chicot and Evangeline aquifers in northwest Harris County, Montgomery County, and southern Walker County. Select the area, distance or location tool below. The aquifer also feeds several well-known recreational springs and underlies some of Texas most environmentally sensitive areas. Their combined freshwater saturated thickness averages about 600 feet in North Texas and about 1,900 feet in Central Texas. Total dissolved solids increase from less than 1,000 milligrams per liter in the east and southeast to between 1,000 and 5,000 milligrams per liter, or slightly to moderately saline, as the depth to the aquifer increases. Aquifers are vital to the states economy and environment, highlighting the need for their proper management and conservation. The aquifer underlies an extensive area in south-central Texas extending along the Balcones fault zone from Kinney County eastward to San Antonio, and thence northeastward to Hays County. Water Systems 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 aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. The Wilcox Group and overlying Carrizo Sand form a hydrologically connected system of sand locally interbedded with clay, silt, lignite, and gravel. Located west of the Franklin Mountains, the Mesilla Bolson reaches up to 2,000 feet in thickness and contains three separate water-producing zones. In 2008, municipal uses accounted for 62 percent and irrigation accounted for 25 percent of the total pumpage from the aquifer. This dataset documents the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston-Galveston region, Texas for 2019. These aquifers consist of limestones, sands, clays, gravels, and conglomerates. 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. 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.
