# Sept-Rivières Regional County Municipality

Sept-Rivières (French pronunciation:, "Seven-Rivers") is a regional county municipality of Quebec, Canada, in the Côte-Nord region. Its county seat is Sept-Îles.
The census groups Sept-Rivières RCM with neighbouring Caniapiscau Regional County Municipality into the single census division of Sept-Rivières—Caniapiscau. In the 2021 Canadian census, the combined population was 38,240. The population of Sept-Rivières RCM itself was 34,358, of whom the vast majority live in the city of Sept-Îles.

## Geography

Sept-Rivières is located in the central part of Côte-Nord. It is bordered by the regional county municipalities of Manicouagan, Caniapiscau, and Minganie, as well as by the southwest corner of Labrador and by the Gulf of Saint Lawrence. It is mostly covered by the Laurentian Mountains. It is a very sparsely populated and undeveloped region with its population highly concentrated along the coast, mostly at Sept-Îles (about three-fourths of the population).
It allegedly takes its name from seven major rivers that join the Saint Lawrence within the territory: Moisie, Sainte-Marguerite, Trinité, Pentecôte, aux Rochers, Pigou and Manitou. But neither the Trinité River nor the Manitou River reaches the Saint Lawrence within the limits of the regional county municipality, and many other rivers could be amongst those "seven rivers".

## River basins

There are a number of large rivers that flow in a generally north-south direction through Sept-Rivières to enter the Gulf. Near the coast the river basins tend to narrow in towards the river mouth, and between their mouths are areas that drain into the Gulf through smaller streams. From west to east, the larger river basins, which may cover parts of neighboring regions, are:
