Rainy Lake and Namakan Reservoir shallow water bathymetric data, water surface elevations, and recovered high-water marks, 2022
Description
Bathymetric data were collected with a single-beam echosounder in 2022 for 18 selected shallow (0-3 meters) areas to improve a digital elevation model (DEM) for Rainy Lake and Namakan Reservoir created by Environment and Climate Change Canada. Bathymetric data were collected in transects spaced approximately 20 meters apart. In addition to the bathymetric data, the locations and elevations of observed water surface and recovered high-water marks are being provided at select locations because of the high water observed during bathymetric data collection after a spring flood in 2022.
