National Park Service St. Croix National Scenic Riverway - Osceola Bed Observations, 20191017

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-11-03T00:00:00Z
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). This dataset contains reference locations that were obtained while collecting ground-truth information for geologic substrate. For statistical analysis, the locations were selected using random point sampling. The shapefile contains sample location coordinates, a general description of interpreted surficial sediment type, and an indication of mussel presence/absence in the attribute table. These geospatial locations directly correspond to the "still-images" dataset.
