Long Lake
Long Lake is a narrow body of water approximately 80km long with outlets at the north (Kenogami Dam) and south (Long Lake Control Dam) ends. The town of Longlac and the Indigenous communities of Ginoogaming and Long Lake 58 are at the north end of Long Lake. Historically, the lake flowed from south to north passing through the Kenogami and Albany Rivers before flowing into James Bay. However in 1939 the Longlac Diversion was constructed which reversed the flow of water redirecting the water flow through a series of engineered channels into the Aguasabon River and then into Lake Superior at the Town of Terrace Bay. During wet times on Long Lake the Kenogami Dam is opened to release additional water out of Long Lake and into the Kenogami River.
