Multibeam bathymetry and sediment depth data at select locations on the Des Plaines River near Joliet, Illinois, February 1314, 2017

These data are high-resolution bathymetry (river bottom elevation) in XYZ format and measurements of sediment depth in CSV format, generated from the February 1314, 2017, topographic and hydrographic survey of the Des Plaines River near Brandon Road Lock and Dam at Joliet, Illinois. Hydrographic data were collected in three separate areas (approach channel, mooring area, and upstream pool) using a multibeam echo-sounder (MBES) with integrated inertial navigation solution (INS) mounted on a marine survey vessel. Sediment depth data were collected in the approach channel using navigational software and probing equipment mounted on a marine survey vessel.
