Chignecto Bay

Chignecto Bay is an inlet of the Bay of Fundy located between the Canadian provinces of New Brunswick and Nova Scotia and separated from the waters of the Northumberland Strait by the Isthmus of Chignecto. It is a unit within the greater Gulf of Maine Watershed. Chignecto Bay forms the northeastern part of the Bay of Fundy which splits at Cape Chignecto and is delineated on the New Brunswick side by Martin Head.

At its head, Chignecto Bay itself subdivides into two basins, separated by Cape Maringouin:

• Cumberland Basin - the northeast arm of Chignecto Bay (and the Bay of Fundy) between the two provinces, terminating at the Tantramar Marshes and the estuaries of the Tantramar River and Maccan River.
• Shepody Bay - the north arm of Chignecto Bay and is wholly within New Brunswick. Its northern limit is formed at the estuaries of the Petitcodiac and Memramcook Rivers.

Many small named bays line the Bay's coast including Salisbury Bay at the mouths of the Upper Salmon river and Cleveland Bk, site of the Village of Alma, NB.

Chignecto Bay is a northern extension of a rift valley that forms much of the Bay of Fundy.
