Lake St. Lawrence depth information

The bundled Ontario lake-profile record does not provide a maximum-depth value for Lake St. Lawrence. Depth contours may still appear on the interactive map where Ontario has surveyed bathymetry, but those contours are reference information and are not a navigational chart.
