In 2013, the average elevation of Lake Superior was 601.71 ft (183 m). The St. Lawrence River begins at the outlet of Lake Ontario at an elevation of 74.7 m (245 ft) and flows to the Atlantic Ocean where the elevation is zero (sea level). So the difference in elevation between the Lake and the River ranges from about 357 feet to about 602 feet, depending on where on the River you measure.
