In 2019 the National Park Service began preparing for the relocation and upgrade of the Osceola (WI) boat ramp in the St. Croix National Scenic Riverway. Prior to construction, hydrographic/topographic surveys and benthic maps of the river bottom were desired to mitigate potential impacts to mussels or benthic habitat. Multibeam Echosounder Systems produce high-resolution bathymetry and backscatter data that can be used to obtain information about the sediment composition and physical properties of the riverbed. A suite of hydroacoustic products (e.g., bathymetry, topobathy, backscatter mosaic, measured river current velocities (ADCP), sidescan mosaic, and underwater images (ground truthing)) were combined to map geomorphic landforms and the surficial sediment type of the river bottom.
