Lake Couchiching (// KOO-chə-ching), 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.
In a 2012 study, the lake showed a microalgae density of 2.4 × 10^7/cm^2, with a high species diversity. The lake showed low total phosphorus and high organic carbon content, when compared to Lake Simcoe.
