Larry French, director of the groundwater division at the Texas Water Development Board, spoke to Texas Standard about its potential . Edwards (Balcones Fault Zone) (San Antonio-oriented) The Texas Water Development Board recognizes and names 15 such aquifers. In Harris, Galveston, Fort Bend, Jasper, and Wharton counties, water level declines of as much as 350 feet have led to land subsidence. 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. See more information on Water Issues and the Texas economy. (February 2005), Valley and Ridge carbonate-rock aquifers were removed:these now should be included in Valley and Ridge aquifers. A .gov website belongs to an official government organization in the United States. Years of heavy pumpage have caused significant water-level declines in portions of the aquifer. The Geologic Atlas of Texas illustrates the surface extent of geologic formations (and aquifers) across the state. Texas Water Development Board works best with JavaScript enabled. January 31, 2023. Aquifers play a major role in providing water to many parts of 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>. 500--Sandstone and carbonate-rock aquifers. Five GCD's (Red on the map), the GMA12, are required to work together to set these conditions for the Carrizo-Wilcox Aquifer. Irrigation accounts for more than half of the aquifer's discharge. It is the third most important groundwater resource in Texas after the Edwards and the Ogallala aquifers. 600--Igneous and metamorphic-rock aquifers. Alluvial aquifers--consist of stream-valley aquifers and other aquifers of unconsolidated alluvial materials, not included in another named national aquifer, south of the limit ofQuarternarycontinental glaciation and east of the Rocky Mountains. This list of national principal aquifer codes and names are fixed values assigned by the National Water Information System (NWIS). These aquifers span many counties and most of the major aquifers extend beyond Texas borders. There are nine major aquifers and 22 minor aquifers that supply groundwater for municipal and irrigation needs throughout the state.

The Aggregate Water-Use Data System (AWUDS) is the database management system used to enter, store, and analyze state aggregate water-use data. He got the county through the crisis, and thanks to some heavy rains in 2012, the aquifer rebounded a little. Click any position on the map to reveal attributes for a specific location. Find out the correct way to pronounce Mexiaalong with hundreds of other places all across Texasby downloading our helpful Pronunciation Guide For the distance tool click points on the map to build line segments to measure and double click to complete the measurement. Aquifers play a major role in providing water to many parts of Texas. In 2008, about 72 percent of pumpage from the aquifer was for municipal use. In 2008, irrigation accounted for 43 percent of water pumped from the aquifer, and municipal supply accounted for 47 percent. About 32 percent of water used to meet municipal demands is from groundwater. A two-dimensionalmap representation of the principal aquiferswas derived from this data and published as part of the National Atlas in 1998 (revised 2003). Elsewhere, water from the Trinity Aquifer is used primarily for municipal and domestic supply. 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 pumping accounts for slightly more than half the water pumped, and pumping for municipal supply accounts for another 40 percent. Last fall while exploring for oil and gas deposits in southwest Texas, a driller instead found a huge freshwater deep aquifer. Beets will help keep Bexar County roads from freezing this week. Elevation (ft) Well Depth (ft) Water Level Observation Type. Texas Water Development Board works best with JavaScript enabled. 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. Groundwater also supplies about 35 percent of the states municipal needs. 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. Click any position on the map to reveal attributes for a specific location. 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 dataset, published in 2002, represents the extent of the alluvial and glacial aquifers north of the southern-most line of glaciation.
