AuSable River

The Ausable River is a river in southwestern Ontario Canada which empties into Lake Huron at Port Franks, Ontario. The Ausable's initial source is in a moraine near the community of Staffa, Ontario located in the municipality of West Perth, Ontario at a point 328 meters (1075 feet) above sea level. Although the river has a total measured length of over 240 kilometers (150 miles), because of its meandering course, the mouth in actuality is only 64 kilometers (40 miles) from its source near Staffa. The Ausable drains 1142 square kilometers (665 square miles) of land, and falls 152 meters (500 feet) in elevation from source to outlet.
