Since the 1940's, commercial, academic and government hydrologists have used aquifer tests to estimate the hydrogeologic properties of an aquifer near test wells. Results from these tests are recorded in various files, databases, reports, and scientific publications. The U.S. Geological Survey (USGS), Lower Mississippi-Gulf Water Science Center (LMG) is aggregating all aquifer test results from Alabama, Arkansas, Louisiana, Mississippi, and Tennessee into a single dataset that is publicly available in a machine-readable format. This dataset contains information and results from 2,245 aquifer tests compiled for aquifers located in Arkansas, Louisiana, and Mississippi. Descriptive statistics for the December 2020...

Water-borne towed transient electromagnetic method, commonly referred to as FloaTEM, was acquired along a single survey track on the Ouachita River during October 2018. During the survey, 39.75 line-kilometers were collected near Blankston, Louisiana study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, and Lower-Mississippi Gulf Science Center and the Aarhus University Hydrogeophysics Group. FloaTEM data acquired along the approximately 40 line kilometers of the Ouachita River in Caldwell County, in Louisiana,were collected to characterize the subsurface resistivity structure in support of a U.S. Geological Survey groundwater investigation of the Mississippi Alluvial...
As demands on groundwater continue to increase, decision-makers need all available information to ensure the sustainability of this important natural resource. Since the 1940's, commercial, academic, and government hydrologists have used aquifer tests to estimate the hydrogeologic properties of an aquifer near test wells. Results from these tests are recorded in various files, databases, reports, and scientific publications. The Lower Mississippi-Gulf (LMG)-Hydrogeologic Aquifer Test dataset aggregates aquifer test results from Alabama, Arkansas, Louisiana, Mississippi and Tennessee into a single dataset that is publicly available in a machine readable format. The dataset includes the following information: Location...

Electrical resistivity results from four regional airborne electromagnetic (AEM) surveys (Burton et al. 2024, Hoogenboom et al. 2023, Minsley et al. 2021 and Burton et al. 2021) over the Mississippi Alluvial Plain (MAP) were combined by the U.S. Geological Survey to produce three-dimensional (3D) gridded models and derivative hydrogeologic products. These products were first published using data from the first two AEM regional surveys, labeled with the year “2020” (Minsley et al. 2021, Burton et al. 2021). The 3D resistivity models and select derivative products were later updated by incorporating additional data from the two subsequent AEM surveys, labeled with the year “2022” (Burton et al. 2024, Hoogenboom et...

This data release consists of two .csv files of inverted models of electrical resistivity created from the processed resistivity data in the accompanying two data releases: (Miller and Others, 2018) and (2018 Raw and Processed, in progress). During 2016, 17, and 18, the U.S. Geological Survey conducted continuous resistivity profiling along 15 rivers or lakes in the Mississippi Alluvial Plain of Mississippi, Arkansas, Louisiana, and Missouri to characterize streambed hydraulic conductivity values. These techniques characterize the near surface geomorphology of the streambed that controls the recharge to the alluvial aquifer. These data can be used to map changes in the lithology of the streambed and identify areas...
