This report describes bathymetric grid data and digitized shorelines compiled for the five Great lakes and Lake St. Clair. The bathymetric grids consist of an array containing the average lake depths in 2-km squares (1.2-km squares for Lake St. Clair). The digitized shorelines are lists of latitudes and longitudes for closed loops describing lake and island shorelines. Conversion equations for map-to-geographical and geographical-to-map coordinate transformations are given for all the bathymetric grids. An appendix details in the format of the data base.
