Data from two bathymetric surveys of the Sandusky River near Bradys Island, Fremont, Ohio, March 2023 and May 2024.
As part of the Great Lakes Restoration Initiative (GLRI) project template 774-GC10 entitled, “Characterization of hydrology and sediment mobility to inform design and implementation of a seasonal barrier to disrupt invasive grass carp reproduction in the Sandusky River near Brady’s Island, Ohio”, two bathymetric surveys of the Sandusky River from the Hayes Avenue bridge to the Ohio State Route 6 bridge were completed. The first survey was done by the U.S. Geological Survey (USGS) on March 1, 2023 and the second was started on May 29, 2024 and was completed May 30, 2024. These data were collected to inform the feasibility of potentially installing a grass carp deterrent barrier on the Sandusky River near Bradys Island. The surveys consisted of measuring bathymetry at cross sections, spaced approximately 200 feet apart, and a streamwise transit of the study section. Surveys were completed using a manned survey vessel with a two-person survey crew. All data were georeferenced using a Global Navigation Satellite System (GNSS) receiver mounted on the survey vessel. Depths were measured using a Teledyne RD Instruments RiverPro acoustic Doppler current profiler (ADCP) deployed on a fixed mount from the survey vessel. Data were processed first in Teledyne RD Instrument's WinRiver II (TRDI, 2023) and then using the Velocity Mapping Toolbox's bathymetry batch mode (Parsons and others, 2012). The Velocity Mapping Toolbox exports the bathymetry data from the four individual beams of the ADCP, corrected for heading, pitch, and roll.
