Lake Simcoe
Lake Couchiching ( ), from the Ojibwe "gojijiing" meaning "inlet", is a medium-sized lake in Central Ontario separated from Lake Simcoe by a narrow channel. The Trent-Severn Waterway enters Lake Simcoe by the Talbot River and exits this lake by the Severn River which empties into Georgian Bay. The lake is 16 km long and slightly less than 5 km wide. The city of Orillia is located on the narrow channel connecting this lake with Lake Simcoe.
