Summary

The U.S. Geological Survey (USGS) collected hydroacoustic data of the St. Croix River adjacent to the Osceola (WI) boat ramp for hydrographic and benthic mapping prior to the reconstruction project implemented by the National Park Service (NPS). High-resolution bathymetry data was surveyed using a multibeam sonar. The depth and characteristics of the riverbed are important parameters of habitat for benthic (bottom-dwelling) organisms, and are a fundamental parameter for riverine ecosystems. A terrestrial lidar unit was used to collect shoreline elevation points. These datasets were desired by the NPS to help inform and mitigate potential impacts to mussels or benthic habitat.

Purpose

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.
