Apart from the passage of the river near hamlet and near the village of Saint-Basile, the Rivière des Sept Îles flows mainly in agricultural and forestry areas, being the main economic activities of this small valley .

[1] The surface of the Sept Îles river (except the rapids areas) is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally from late December to early March.

The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.

This area is south of Mount Laura-Plamondon (summit at 251 m), north of another mountain (altitude 253 m) and west of the Paquet airfield.

[2] The toponym "Rivière des Sept Îles" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
