In this view to the south of the bridge, one sees Fullers River as it flows to its entrance into the Atlantic. The main flow of Fullers River is from the right of the photo to this side of the “island” (actually behind the beach at Framboise Cove and connected to it) left of centre and on out across the narrow channel east of the beach near Winging Point. The flow from MacKenzies River into Fullers River is at the far left of this photo and mostly outside its scope. If you look at the center of the photo on the far horizon, you will see Red Cape sticking up beyond Morrisons Beach.
I do not know whether the water here is fresh or brackish, but this scene has the look of many a salt-water estuary and the currently uncovered areas also seem to suggest a tidal variation, so I’d guess that there is some inflow from the Atlantic here.
The coastal terrain has already significantly changed its character here; east of St-Esprit Lake to Gabarus and on to Louisbourg, a plethora of bogs, marshes, lakes, and rivers lie just inland of the Atlantic coast, much of which consists of great sandy strands; to the west of the lake, the land is hillier and cliffs, though broken by brooks and rivers coming down to the sea, line the coast.
