Nova Scotia's rivers all flow into the Atlantic Ocean through four unique watersheds: the Gulf of Maine, the Northumberland Strait, the Gulf of Saint Lawrence and into the Atlantic Ocean itself.
Gulf of Maine
The Gulf of Maine system includes the Bay of Fundy, which includes the Cumberland and Minas Basins. In Nova Scotia, the system occupies the shores from Fort Lawrence to Cape St. Mary (44°05′N).
Bay of Fundy
The Bay of Fundy coastline in Nova Scotia begins at Fort Lawrence and circles Cape Chignecto eastward to Truro. It then follows west along the Annapolis Valley as far as Brier Island on the Digby Neck. Within the Bay of Fundy are two basins: Chignecto Bay which begins at Fort Lawrence and ends at Cape Chignecto, and the Minas Basin that encompasses everything east of Ramshead Point (near Diligent River) and Cape Split.
