St. Croix River - Bathymetry Hillshade- 2018

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 09:17 PM | Dataset Last Updated: November 03, 2021 at 12:00 AM
Hydroacoustic (sonar) data were collected for the Mississippi, St. Croix, and Minnesota Rivers for the development of high-resolution bathymetry and sidescan imagery. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. These information needs were highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution. The collaborative effort was funded by the Legislative-Citizen Commission on Minnesota Resources (LCCMR) Environment and Natural Resources Trust Fund (ENRTF), to help maintain and enhance Minnesota’s environment and natural resources.
