The Edwards-Trinity (High Plains) Aquifer is a minor aquifer that underlies about 9,000 square miles of the Ogallala Aquifer in western Texas and eastern New Mexico. Its water-producing units include sandstone of the Antlers Formation (Trinity Group) and limestone of the overlying Comanche Peak and Edwards formations.Water in this region comes largely from the High Plains Aquifer system, made up largely of the Ogallala aquifer. The High Plains Aquifer system is one of the largest freshwater aquifers in the world and underlies approximately 111 million acres in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, …The secondary aquifers discussed include the Chadron, Brule, and Upper Cretaceous aquifers in western Nebraska and the Western Interior Plains, Dakota, Codell, and Niobrara aquifers in eastern Nebraska. “More than one secondary aquifer is used in some counties,” Divine said. “The maps in this. publication are printed on transparent ...Amy Kremen, Ogallala Water CAP project manager, Department of Soil and Crop Sciences at Colorado State University, said a continuing theme throughout the meeting was, “With limited water in the High Plains, the question is less about production that needs to feed the world’s population of 8 billion, it’s about keeping rural communities ...McGuire, V. L. Water-level Changes and Change in Water in Storage in the High Plains Aquifer, Predevelopment to 2013 and 2011–13 Scientific Investigations Report 2014–5218 (US Geological ...The effects of groundwater pumping and water-level declines in east-central New Mexico are similar to those observed in the High Plains aquifer across northwest ...To illustrate the classification approach, a study of the High Plains aquifer system accounted for recharge as: precipitation sourced; groundwater-sourced irrigation-return flow; surface-water-sourced irrigation-return flow; canal leakage; and surface-water sourced recharge from natural landscape features (playas, lakes, and streams; Stanton …The Ogallala, or High Plains Aquifer, ranks as the largest such groundwater source in the U.S. Stretching from Texas and New Mexico to South Dakota and Wyoming, it underlies eight states and represents more than one-quarter of the nation’s entire irrigation water. In terms of agricultural output, it supplies an area that produces ...Jan 1, 2002 · The High Plains aquifer is the largest freshwater aquifer in the United States (Sophocleous, 2005), providing about 30% of the nation's irrigation groundwater (Dennehy et al., 2002) and more than ... The High Plains aquifer (HPA), which includes the Ogallala aquifer, is the primary source of water for western Kansas and is economically the most important groundwater resource in the state. This aquifer and the river-reservoir systems located principally in eastern Kansas are identified as the two most critical water resource components of ... In Castro County in 2022, the High Plains Water District reported Ogallala’s saturated thickness to be around 53 feet; in the last 10 years, Castro County has lost nearly 19 feet. Since 2021 ...To help protect this vital resource, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Project assesses groundwater quality in aquifers that are …McGuire, V. L. Water-level Changes and Change in Water in Storage in the High Plains Aquifer, Predevelopment to 2013 and 2011–13 Scientific Investigations Report 2014–5218 (US Geological ...The High Plains aquifer is the principal source of ground water for the High Plains region, which is one of the Nation's most important agricultural areas. In Nebraska, the aquifer underlies an area of about 63,650 square miles, and in Kansas, it underlies an area of about 30,500 square miles; only these parts of the aquifer are discussed in ...Irrigation is essential to much of this crop production. Irrigated agriculture across the High Plains accounts for 30% of all irrigated acreage in the U.S. (Dennehy et al., 2002), and 97% of High Plains irrigation water is extracted from the High Plains Aquifer (The High Plains Aquifer, USA, n.d, Maupin and Barber, 2005).This report contains the major findings of a 1999–2004 assessment of water quality in the High Plains aquifer. It is one of a series of reports by the National Water-Quality Assessment (NAWQA) Program that present major findings for principal and other aquifers and major river basins across the Nation.Jul 25, 2019 · The High Plains aquifer, also known as the Ogallala aquifer, is the largest aquifer in the United States. It stretches across approximately 174,000 square miles and 8 different states in the Midwest. This aquifer provides around 30% of the water used to irrigate agricultural crops in the U.S.

Furthermore, the lake’s residue’s estimated age is ~1.1 Ga (~3.2 Ga post-peak aquifer drainage during the Late Hesperian), enhancing the prospects for organic …Sep 11, 2017 · Nebraska is a groundwater-rich state. Nebraska has one primary aquifer, the High Plains Aquifer, and seven secondary aquifers. These secondary aquifers supply water to more than 4000 active wells spread across 30 counties. Agricultural Production from the High Plains Aquifer Is Worth Over $3 billion per Year. Recent research (Garcia, Fulginiti and Perrin, 2018) has shown that the extra agricultural production from irrigation across the High Plains Aquifer (HPA) was worth about $3.5 billion in 2007, $2 billion of which was produced in Nebraska.We restrict our analysis on the well-year combinations where (a) the well is located within the High Plains Aquifer extent and pumps from a groundwater source, and (b) water use is measured by state certified flowmeters (as opposed to being estimated by the irrigator). To reduce the effect of outliers, which may reflect faulty meters or ...

Water-level changes in the High Plains aquifer, predevelopment to 2015. Click on image for larger version. Water-level changes: A rise of 84 ft in Nebraska to a decline of 234 ft in Texas. Declines of 5 ft or more in about 36 percent of the aquifer area. Rises of 5 ft or more in about 8 percent of the aquifer area.but overuse has depleted aquifers around the globe (Wadaetal2010,Gleesonetal2012,Rodelletal2018). In the United States, the High Plains Aquifer (HPA, often labeled by its predominant geologic unit, the OgallalaFormation) supportsmore than $20 billion in annual economic activity (Ashworth 2006).However,Irrigation is essential to much of this crop production. Irrigated agriculture across the High Plains accounts for 30% of all irrigated acreage in the U.S. (Dennehy et al., 2002), and 97% of High Plains irrigation water is extracted from the High Plains Aquifer (The High Plains Aquifer, USA, n.d, Maupin and Barber, 2005).…
