In 2019, more than 90 percent of the water pumped from the Ogallala was used for irrigation, while more than 90 percent of the Hueco-Mesilla pumpage served municipal purposes. Refer to the metadata for a complete description of the files and how they were generated. Total ground-water withdrawals were 76,500 million gallons per day, or 85,800 thousand acre-feet per year for these three uses. 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. Water-level declines are occurring in part of the region because of extensive pumping that far exceeds recharge. Throughout much of the aquifer, groundwater withdrawals exceed the amount of recharge, and water levels have declined fairly consistently through time. The name of N600NECRSN was changedfrom "New England crystalline-rock aquifers" to "New York and New England crystalline-rock aquifers" to better reflect the geographic extent (January 2015). The component aquifers are Lower Tertiary, Upper Cretaceous, Lower Cretaceous, and Paleozoic. These aquifers consist of limestones, sands, clays, gravels, and conglomerates. Latitude (DD) Longitude (DD) County. (Note that the National Aquifer Code uses a different numeric component than the geohydrologic unit names.). 9999--Areas that are not a national aquifer. Additional aquifer data through the USGS web app The aquifer consists of sand, gravel, clay, and silt and has a maximum thickness of 800 feet. This area corresponds to the principal recharge zone for the aquifers. (.pdf file). 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. Share sensitive information only on official, secure websites. For study or mapping purposes, aquifers are often combined into aquifer systems. Edwards (Balcones Fault Zone) (San Antonio-oriented) Groundwater also supplies about 35 percent of the states municipal needs. Most of the carbonate-rock aquifers consist of limestone, but dolomite and marble locally yield water. 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.

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. There are nine major aquifers and 22 minor aquifers that supply groundwater for municipal and irrigation needs throughout the state. 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. 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 span many counties and most of the major aquifers extend beyond Texas borders. The lower, more permeable part of the aquifer produces the greatest amount of groundwater. Well, in Central Texas, and particularly the Edwards Aquifer, it's an aquifer that has a lot of caves in it and fractures. Texas Gulf Coast Groundwater and Land Subsidence Over Forty Years of Research in the Houston-Galveston Region. For an overview ofprincipalaquifers:The principal water-yielding aquifers of North America can be grouped into five types by rock type and location: unconsolidated and semiconsolidated sand and gravel aquifers, sandstone aquifers, carbonate-rock aquifers, aquifers in interbedded sandstone and carbonate rocks, and aquifers in igneous and metamorphic rocks. The aquifer is used for municipal, industrial, and irrigation purposes. Their combined freshwater saturated thickness averages about 600 feet in North Texas and about 1,900 feet in Central Texas.

Throughout most of its extent in Texas, the aquifer yields fresh to slightly saline water that is used mainly for irrigation in the Winter Garden District of South Texas, and for public supply and industrial use in Central and Northeast Texas. Historical large-scale groundwater withdrawals, especially for the municipal uses of El Paso and Juarez, have caused major water-level declines and significantly changed the direction of flow, causing a deterioration of the chemical quality of the groundwater in the aquifer, according to El Paso Water Utilities and the USGS. Such sites will not be retrieved using this search criteria. 500--Sandstone and carbonate-rock aquifers. In general, groundwater is fresh but very hard in the outcrop of the aquifer. Groundwater movement in sandstone aquifers primarily is along bedding planes, but joints and fractures provide avenues for the vertical movement of water. Presented by For a deeper dive into principal aquifers:TheGround Water Atlas of the United States(USGS Hydrologic Atlas 730,published inchapters from 1990 to2000) describes the location, hydrologic characteristics, and geologic characteristics of the principal aquifers throughout thefiftyStates, Puerto Rico, and the U.S. Virgin Islands. He got the county through the crisis, and thanks to some heavy rains in 2012, the aquifer rebounded a little. 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. The Ogallala Formation of late Miocene to early Pliocene age consists of heterogeneous sequen-ces of coarse-grained sand and gravel in the lower part, grading upward into clay, silt, and fine sand.
