At the mouth of the river the Pakuashipi ("sand river") Innu community is on the west shore and the village of Saint-Augustine is spread over hills on the east shore. The two communities are accessible only by sea or air. A barge is used to carry goods across the river, and a hovercraft takes passengers. A new barge was due to be delivered in 2020.

Louis Jolliet (1645–1700) called the river Pegouasiou, and Jean-Baptiste-Louis Franquelin (1650–1712) called it Pegouachiou, meaning "deceptive river", probably given that name by the indigenous people because of it is shallow and the sandbars in its mouth are unstable. The name Saint-Augustin was given to the river in the 18th century, and then to the village on the east shore of its mouth. The name may refer to Augustin d'Hippone, a priest, or to Augustin le Gardeur de Courtemanche (1663–1717), first concessionaire of a strip of land that extended "from the river called Kegaska to that named Kesesakion". ==Basin==
