National Park Service St. Croix National Scenic Riverway - Osceola Bathymetry Hillshade, elevation in feet, 20191016

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 07:35 PM | Dataset Last Updated: November 03, 2021 at 12:00 AM
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. These datasets were desired by the NPS to help inform and mitigate potential impacts to mussels or benthic habitat.
