This data release supports the publication in the Soil and Tillage Research journal titled "Multiyear Crop Residue Cover Mapping Using Narrow-Band vs. Broad-Band Shortwave Infrared Satellite Imagery" by Lamb and others (2025) (https://doi.org/10.1016/j.still.2025.106524) The dataset includes field sampling data comprising in-field nadir photographs collected from a collaborating farm in...

This dataset contains site information and results of flood frequency analysis for 64 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Alabama and Mississippi. Site information and annual peak-flow data from the 1885 - 2024 water years were obtained from the USGS National Water Information System (NWIS) database (U.S. Geological Survey, 2025...

Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed...

Datasets includes groundwater well locations and 2015 water-level measurements for 31 wells, 20-foot contours, and water-level change for 31 wells measured in 2009 and 2015 of the Cockfield (upper Claiborne) aquifer. Data also includes groundwater well locations and 2015 water-level measurements for 37 wells, 10-foot contours of the northern Wilcox aquifer, 20-foot contours of the...

This dataset contains site information and results of flood-frequency analysis for 422 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in parts of the Upper Mississippi and Souris-Red-Rainy basins and surrounding areas in the United States. Annual peak-flow data from the 1844 - 2013 water years were used in the study (U.S. Geological Survey, 2024)...

Karst is a landscape where the hydrology of surface water systems is intricately connected to groundwater systems through the development of conduits and solutional opening in soluble bedrock, such as limestone, marble, or dolomite. This connectivity can present challenges to preserving water quality and quantity for karst aquifers, as activities that occur in karst areas can often have...

The Mississippi River Valley alluvial aquifer (MRVA) in eastern Arkansas is a major source of groundwater for public, industrial, agricultural, and aquaculture uses. Estimated withdrawals from the MRVA increased from 1,063 million gallons per day in 1965 (Halberg and Stephens, 1966) to 7,252 million gallons per day in 2005 (Holland, 2007). Potentiometric-surface maps, which represent the...

Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage...

This data release contains tracer data and estimated age distributions of groundwater samples collected as part of a water availability study for the Mississippi alluvial plain (MAP). The MAP is the floodplain of the lower Mississippi River and its main tributaries and distributaries. The soils, climate, and irrigation water resources of the MAP have made it a highly productive...

Data about the top and bottom altitude, depth from land surface and/or the thickness of three geologic units in Tennessee were converted into geospatial format for this USGS data release from previously published paper maps and converted into digital formats for use by the public. The three geologic units were the Chattanooga Shale of Mississippian-Devonian age (Moore and Horton, 1999)...

The state of Tennessee is divided into 805 individual 7.5-minute topographic quadrangle maps. The Tennessee Department of Environment and Conservation (TDEC) maintains an archive of paper maps that were utilized for estimating groundwater well locations. Each well location was plotted by hand and marked with corresponding water well data. These hand-plotted locations represent the most...

Degradation of water quality from nutrient pollution continues to be a challenge for water resource managers. The development of effective management strategies begins with tools that facilitate an understanding of nutrient sources and transport. SPARROW (SPAtially Referenced Regression On Watershed attributes) is a spatially explicit model platform that correlates water-quality...
