Bathymetry and Storage Capacity of Nimrod Lake, Arkansas

A bathymetric survey of Nimrod Lake, Arkansas, was conducted in late April to mid-May, 2016, by the Lower Mississippi-Gulf Water Science Center (LMG WSC) of the U.S. Geological Survey (USGS) using methodologies for sonar surveys similar to those described by Wilson and Richards (2006) and Richards and Huizinga (2018). Point data from the bathymetric survey were merged with point data from an...

Annual estimates of suspended-sediment concentration and load to support trend analysis on the Mississippi River and Atchafalaya River, 1980-2015

This data release contains annual estimates of suspended-sediment concentration and load for the Mississippi River, St. Francisville site and the Atchafalaya River, Melville site from 1980-2015. Annual estimates and flow-normalized estimates were generated using the Weighted Regressions on Time, Season and Discharge (WRTDS) model. Input data for the model included suspended-sediment...

Digital Elevation Model of the Bathymetry of Blue Mountain Lake, Arkansas

The dataset is a digital elevation model (DEM), in GeoTiff format, of the bathymetric surface of Blue Mountain Lake, Arkansas, within the extent of pool elevation 420 feet (ft) above the North American Vertical Datum of 1988 (NAVD88). The DEM was derived from a terrain dataset created by merging bare earth point data from an aerial LiDAR survey conducted in December 2010 for the U.S. Army...

Irrigated acreage in Tennessee Counties, 1934 to 2012

Understanding water use needed for irrigation is central to water-resource planning and public decision making. Meeting this basic need requires accurate estimates of water withdrawals for irrigated lands and an understanding of how factors driving water-use needs are likely to change in the future. In order to assist local decision makers in Tennessee, the U.S. Geological Survey (USGS), in...

Digital Dataset for the Geomorphology of the Lower Mississippi River Valley in Missouri, Kentucky, Arkansas, Tennessee, Louisiana, and Mississippi

A digital dataset of the geomorphology of the Lower Mississippi River Valley in Missouri, Kentucky, Arkansas, Tennessee, Louisiana, and Mississippi was developed from Roger T. Saucier’s “Geomorphology and Quaternary Geologic History of the Lower Mississippi Valley, Volumes I and II” (1994) as part of the Mississippi Alluvial Plain (MAP) Regional Water Availability...
