The Sous River, Sus River or Souss River (Berber: Asif en Sus, Arabic: واد سوس) is a river in mid-southern Morocco located in the Sous region. It originates in the High Atlas and flows west passing Aoulouz, Taroudannt, Oulad Teima, Inezgane and Aït Melloul. It forms a basin which is protected from the desertic climate of the Sahara by the Anti-Atlas mountains and is one of Morocco's most fertile regions.[1]
The Aoulouz Dam is the main dam on this river.
