Spatial data set of the potentiometric surface contours, Mississippi River Valley alluvial aquifer, spring 2016, in feet
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the 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...
Coosa River Bank Topography and Comparisons at Neely Henry Dam sites NH104 and NH108, near Gadsden, Alabama, January 2015 - July 2017
These datasets contain XYZ locations and other attributes of points from topographic bank surveys of sites NH104 and NH108 downstream from H. Neely Henry Dam near Gadsden, Alabama, from January 30, 2015, through July 19, 2017. Topographic data were collected using a motion-compensated LiDAR (MC-LiDAR) system mounted on a marine survey vessel equipped with an inertial navigation system (INS)....
Groundwater altitude data, from monitoring-networks wells, considered for the potentiometric surface map, Mississippi River Valley alluvial aquifer, spring 2016
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the 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...
Generalized regions of the Mississippi Alluvial Plain
As part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program study of the Mississippi Alluvial Plain (MAP), a shapefile representing seven generalized regions of the MAP extent as defined by Painter and Westerman (2018) was compiled. The generalized regions provide a framework for analysis, visualization, and regional comparisons of local data within the MAP....
Groundwater withdrawal zones for drinking water from the Mississippi River Valley alluvial aquifer and Mississippi embayment aquifers
Of the approximately 6.6 million people living in the Mississippi embayment (MISE) region in the central United States, approximately 65 percent rely on groundwater for their drinking water (Dieter, Linsey, and others, 2017). Regional assessments of water quality in principal aquifer systems provide context for the long-term availability of these water resources for drinking-water supplies. To...
Groundwater altitude data, from driller-measured wells, considered for the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2016
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages.

Surface-water altitude data, from streamgages, considered for the potentiometric surface map, Mississippi River Valley alluvial aquifer, spring 2016
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages.

Water-borne continuous resistivity profiling data from select streams of the Mississippi Alluvial Plain in northwestern Mississippi
This data release consists of two different datasets, waterborne resistivity profiling data and water quality data collected during profiling. In fresh water aquifers, the geoelectric resistivity of earth materials commonly has a positive correlation with hydraulic conductivity. In June 2016, continuous resistivity profiling data were collected, as a proxy for streambed hydraulic...
Estimated baseflow and runoff using estimated and measured streamflow, five selected sites, Mississippi Delta
This data set provides estimated and measured streamflow data and hydrograph-separation results for five sites located in northwest Mississippi. Streamflow data were collected by the U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers. Hydrograph-separation results provide runoff and baseflow estimates at each site that were calculated using four methods: PART, HYSEP Fixed,...
Lake St. Joseph
Nutrient and phytoplankton data indicate poor environmental health in four oxbow lakes in central Louisiana suggesting that long-term agriculture practices and increases in shoreline development have accelerated eutrophication. Surface-water quality and phytoplankton indicators of eutrophication were examined at Lake Bruin, Lake St. John, Lake St. Joseph, and False River Lake along an...
Potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2016, raster format, in meters
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages.

Digitized Contours from Georeferenced Plate from "Analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment" (Reed, 1972)
A digital dataset of analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment in Missouri, Kentucky, Arkansas, Tennessee, Louisiana, and Mississippi was developed from J.E. Reed's "Analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment" (1972). The plate was georeferenced to North American Datum 1983 and projected to USA Contiguous...
