Abstract: 

This website provides Great Lakes bathymetric data to the public and especially to the communities concerned with Great Lakes science, pollution, coastal erosion, response to climate changes, threats to lake ecosystems, and health of the fishing industry. This program was managed by NGDC and relied on the cooperation of NOAA/Great Lakes Environmental Research Laboratory, NOAA/National Ocean Service, the Canadian Hydrographic Service, other agencies, and academic laboratories.

Please note that the bathymetric data for Lake Superior is incomplete

Attributes associated with this data:  Aquatic Environment, Depth, Digital Elevation Model, Erie, Huron, Michigan, Ontario.

A tutorial explaining how to retrieve data from the website and how to convert it into a usable DEM is available at the following link: http://library.mcmaster.ca/maps/Accessing_Great_Lakes_Bathymetry_Data.pdf
