Geodatabase containing bathymetric and LiDAR data for DeQueen Lake, Sevier County, Arkansas, 2015.

A bathymetric survey of DeQueen Lake, Sevier County, Arkansas was conducted in July, 2015, by the Lower Mississippi-Gulf Water Science Center of the U.S. Geological Survey (USGS) using methodologies for multi-beam sonar surveys similar to those described by Lee, K.G. (2013) and Huizinga (2016). XYZ (point) data from the bathymetric survey were merged with XYZ (point) data from an aerial LiDAR survey conducted in March, 2008 for the U.S. Army Corps of Engineers, Little Rock District and stored in a feature dataset within the geodatabase. A terrain (digital terrain model, or DTM) of the lakebed below flood pool elevation 474 ft above the North American Vertical Datum of 1988 (NAVD88) was created from the XYZ (point) data and stored in the geodatabase. Child items derived from the DTM and stored in the geodatabase include a digital elevation model (DEM) in Esri GRID format with a cell size of 3 ft, a feature class of elevation contours at 10-ft intervals, a table of surface area and storage capacity (volume) of the lake at 1-ft increments in water surface elevation, and a python script used to incrementally compute the storage capacity.
