Bathymetry and Storage Capacity of Nimrod Lake, Arkansas

September 4, 2018

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 aerial LiDAR survey conducted in December, 2010, that were provided by the U.S. Army Corps of Engineers (USACE), Little Rock District. From the combined point dataset, a terrain dataset (a type of triangulated irregular network, or TIN, model) was created in Esri ArcGIS, version 10.5, for the area within the approximate extent of the flood pool of the lake as defined by the 374-ft contour of the LiDAR data. Products in this data release are stored within an Esri file geodatabase and include the following: Feature classes of point data from the bathymetric and LiDAR surveys; the terrain dataset; a feature class of bathymetric contours at 4-ft intervals; and a table of storage capacity (volume) of the lake at 1-ft increments in water surface elevation from 301-373 ft above the North American Vertical Datum of 1988 (NAVD88), seasonal conservation pool elevations 342.13, 344.63, and 345.13 NAVD88, and flood pool elevation 373.13 ft NAVD88.
