Description: The lake contours were digitized by a number of different sources, but largely through the GIS group at the Institute for Fisheries Research. Lakes are associated with a New Key, a unique identifier that is a combination of a country code with a unique lake code (Breck, 2004; Humphrys and Green, 1962). They are also associated with unique identifiers linking them to the USGS NHDPlus HR and MDNR Hydrography frameworks.Each contour has a maximum and minimum depth. The minimum depth is the value of the contour line and the max value is either the value of the next deepest contour or the deepest point within the contour if there is no next deepest contour.
