Shaded Relief of the Bathymetry near Shorty's Island and Myrtle Bend, 2010, Kootenai River near Bonners Ferry, ID

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: August 25, 2025 | Last Modified: 20201117
The shaded relief raster data was created based on bathymetry obtained in the meander reach collected in about a one month period extending from 6/3/2010 - 6/19/2010. This subset data extends from river kilometer designator 228 upstream to 237. Similar methods used to collect and process the bathymetry are described in Fosness (2013). The shaded relief was created from a surface raster (also referred to as digital elevation model) of the bathymetry data and displays the illumination angle of the surface raster. The shaded relief data provides an appearance of three-dimensional space through the use of shading and lighting.
