These data are bathymetry (river bottom elevation) in XYZ format, generated from the April 4-5, 2017, bathymetric survey of the Rolling Fork and Beech Fork near Boston, Kentucky. The bathymetry was collected from approximately 1.9 miles upstream from Kentucky State Highway 62 on the Beech Fork and approximately 1.5 miles upstream from Kentucky State Highway 62 on the Rolling Fork, to 2.6 miles downstream from Kentucky State Highway 62 on the Rolling Fork. Hydrographic data were collected using an acoustic Doppler current profiler (ADCP) with integrated Differential Global Positioning System (DGPS). Data were collected as the surveying vessel traversed the river, approximately perpendicular to the velocity vectors at 70 cross sections which were spaced approximately 500 feet apart along the river. Data collection software integrated and stored the depth and DGPS data from the ADCP. Real-time kinematic GPS was collected recording the water-surface elevation. Data processing required computer software to extract bathymetry data from the raw data files and to compile the information. The final csv file contains columns of Easting and Northing in meters WGS84 - UTM Zone 16N, and Elevation in feet NAVD88.
