Aux Rochers River

Aux Rochers River (French: Rivière aux Rochers, pronounced [ʁivjɛʁ o ʁɔʃe], Rocky River), is a river in Sept-Rivières Regional County Municipality, Côte-Nord, Quebec, Canada. It drains an area of 4,180 square kilometres (1,610 sq mi). It is a tributary of the Gulf of Saint Lawrence

The Aux Rochers River is in Port-Cartier, Sept-Rivières. It empties into the Gulf of Saint Lawrence in the town of Port-Cartier. One of its tributaries, the Gravel River, is sometimes also called the Aux Rochers River. The Gravel flows south to the long Lake Walker. The Aux Rochers River proper leaves the south end of Lake Walker and flows southeast for a further 30 kilometres (19 mi). The river is hard to navigate due to a strong current. It also contains many rocks, hence its name. Some of the smaller rocks move to different places in the river each year. The lower river valley is used by southern section of the Cartier Railway, which then runs along the east shore of Lake Quatre Lieues before following the valley of the MacDonald River, a tributary of the Aux Rochers.

A map of the Ecological regions of Quebec shows the river rising and flowing south through the eastern spruce/moss domain of the boreal zone. The last section of the river flows through the fir/white birch domain of the boreal zone.
