Sarnia is located on the eastern shore of Lake Huron at its extreme southern point, where it flows into the St. Clair River. Most of the surrounding area is flat, and the elevation ranges from 169 to 281 m (554 to 922 ft) above sea level. The soil mostly comprises clay. Despite this high percentage of clay, the soil is remarkably rich for cultivation.
