The Beaver River in in Grey County flows from the Niagara Escarpment to empty into Nottawasaga Bay, an inlet of Georgian Bay, at Thornbury, Ontario at 44°33′54″N 80°26′52″W. The Beaver Valley is a deep wedge on the western side of the escrarpment, formed by a much larger ancestor of this river. A fish ladder near Thornbury allows fish to reach spawning areas up river. The river is also a popular recreational canoe route. The Boyne River joins this river near Eugenia Falls where the Beaver River falls over the escarpment. There is a hydroelectric plant at these falls; Lake Eugenia was formed when the river was dammed to control river flow. The Beaver River valley is home to a number of downhill ski clubs. The river's drainage basin is under the auspices of Grey Sauble Conservation.
