Data from the bathymetric survey were merged with data collected during a March 2008 aerial LiDAR survey provided by the U.S. Army Corps of Engineers, Little Rock District.  Using Esri ArcGIS version 10.3.1, a feature dataset of the XYZ points from the merged LiDAR and bathymetry data was created within a file geodatabase and an associated terrain (digital terrain model, or DTM) created from the XYZ feature dataset.  Products derived from the DTM include a digital elevation model (DEM), bathymetric contours at 10-ft intervals, and surface area and storage capacity (volume) of the lake at 1-ft intervals in the range of elevation from 349-580 ft above the North American Vertical Datum of 1988 (NAVD88).
