Great Slave Lake, in the southern part of the District of Mackenzie, Canada, is an immense inland sea (area 11,821 square miles). It is navigable throughout its whole length and breadth. At its western end the Mackenzie River which flows into the Arctic Ocean (one of the eight largest rivers in the world) has its starting point. The southern shore of the lake has good agricultural prospects.
