The area near Shellmound, Mississippi is the focus of a U.S. Geological Survey (USGS) hydrologic mapping and modeling effort to support a managed aquifer recharge pilot study being conducted by the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) and other local stakeholders. The pilot study is investigating the use of bank filtration from a gallery of extraction wells adjacent to the Tallahatchie River. This extracted water could be used as a source of focused aquifer recharge via injection wells in an area of groundwater decline in the Mississippi River Valley alluvial aquifer (MRVA). To support this investigation, the USGS Mississippi Alluvial Plain (MAP) Regional Water Availability Study carried out airborne and ground-based geophysical studies in the area to improve understanding of the geology and structure of the aquifer system.
This animation shows a 3D fly-through of the aquifer represented by the top and bottom elevation surfaces developed from the airborne geophysical survey and shown in the "Derived Aquifer Properties" tab above. Locations of proposed injection and extraction wells for the managed aquifer recharge pilot study are also indicated. Together, these data help to visualize the detailed aquifer geometry in the vicinity of these wells.

Mississippi Alluvial Plain (MAP): Water Availability Study
The Mississippi Alluvial Plain is one of the most productive agricultural regions in the Nation and depends on groundwater for irrigation. The MAP area constitutes the third largest area of irrigated cropland in the United States. The area is approximately 29,000 square miles (19 million acres) and includes parts of the States of Missouri, Tennessee, Arkansas, Mississippi, and Louisiana.The U.S...Mississippi Alluvial Plain (MAP): Water Use and Availability Program

Airborne electromagnetic, magnetic, and radiometric survey, Shellmound, Mississippi, March 2018
Airborne electromagnetic (AEM), magnetic, and radiometric data were acquired in late February to early March 2018 along 2,364 line-kilometers in the Shellmound, Mississippi study area. Data were acquired by CGG Canada Services, Ltd. with three different helicopter-borne sensors: the CGG Canada Services, Ltd.

The Mississippi Alluvial Plain (MAP) Project contains several geologic units which act as important aquifers. We collected several sets of time-domain electromagnetic (TEM) data consisting of two higher-density surveys and six regional-scale transects. The higher density surveys were collected to compare and contrast to other geophysical data not included in this data release, such as airborne ele - Maps
High-resolution airborne geophysical survey of the Shellmound, Mississippi area
In late February to early March 2018, the U.S. Geological Survey acquired 2,364 line-kilometers (km) of airborne electromagnetic, magnetic, and radiometric data in the Shellmound, Mississippi study area. The purpose of this survey is to contribute high-resolution information about subsurface geologic structure to inform groundwater models, water resource infrastructure studies, and local decisionPotentiometric surface of the Mississippi River Valley alluvial aquifer, spring 2016
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer using selected available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time after installation, but some wells were measured more than one time or continually; streamgages are typically operated coGeostatistical estimation of the bottom altitude and thickness of the Mississippi River Valley alluvial aquifer
The Mississippi River Valley alluvial aquifer (MRVA) caps a shallow system of aquifers and confining units in the Mississippi Alluvial Plain (MAP) that extends across 45,000 square miles of the midwestern and southern United States from Illinois to Louisiana. Irrigation water from the MRVA is required to sustain extensive crop production, which has resulted in groundwater-level declines since the
