Most of the watershed is in Kent County with a small section to the southwest located in the Westmorland County. Water from the territory flows into the Northumberland Strait drainage basin, which is part of the Gulf of St. Lawrence ecosystem. This territory has an area of 400 km2 and includes the Cocagne River Watershed, the Cocagne Bay or Harbor as well as several small watersheds to the north of the Cocagne River, all flowing directly into the Northumberland Strait. To the east, the bay reaches Cap de Cocagne. Cocagne Island and Treasure Island (Île de Surette) as well as Barre de Cocagne are coastal characteristics of this watershed.
The aquatic boundaries of the Cocagne Bay Watershed are determined by the flow divide of the neighboring salt water watersheds of Bouctouche Bay to the north and Shediac Bay to the east.
A variety of habitats can be found in that region. Land close to the bay reveals several areas of salt marshes as well as low undulating hills with forested and agricultural areas. The region has many primary and secondary residences. Wetlands include also peatland, mostly in the upper part of the river watershed.
Several communities in South-East New Brunswick such as Cocagne, Notre-Dame, Irishtown,Saint-Antoineand Grande-Digue are part of the territory being studied. The local economy relies on natural resources as well as on goods and services the region has to offer because of its proximity to Moncton, Dieppe, Riverview, Shediac and Bouctouche.
