Geodatabase containing bathymetric and LiDAR data for Norfork Lake, Arkansas-Missouri, 2015.

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.
