Summary
A bathymetric survey of Norfork Lake, Arkansas-Missouri, was conducted in September-October, 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 (2013) and Huizinga (2016). Point (XYZ) data from the bathymetric survey were merged with XYZ data collected during a March 2008 aerial LiDAR survey provided by 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) was created from the XYZ data and stored in the geodatabase. Products derived from the DTM and stored in the geodatabase include a digital elevation model (DEM), [...]
Summary
A bathymetric survey of Norfork Lake, Arkansas-Missouri, was conducted in September-October, 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 (2013) and Huizinga (2016). Point (XYZ) data from the bathymetric survey were merged with XYZ data collected during a March 2008 aerial LiDAR survey provided by 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) was created from the XYZ data and stored in the geodatabase. Products derived from the DTM and stored in the geodatabase include a digital elevation model (DEM), a feature class of elevation contours, a table of surface area and storage capacity (volume) of the lake, and a Python script used to incrementally compute the storage capacity.

Purpose
The DTM in the Esri file geodatabase and products derived from it are intended to be used to update the published storage capacity and bathymetric maps of Norfork Lake and provide a foundation for interpretive work. The DTM can be used to create DEMs at various resolutions and bathymetric contours at various intervals.
