The Oued Harr is a river located in Salamat. It forms at Mount Khabbani, at more than 2150 meters above sea level, and flows in the provinces of Jabal Zalzabiya and Douarani. It flows in the city of Zalzab, and provides water to the local populations in the mountains. It flows eastward into the Douarani Province, then reaches its maximum width at 573 meters, north of El Kheroubi. The river flows into the Harr Lake. The river loses water due to excessive cotton farming in the area and experts predict that the Oued Harr will become a small irrevelant oued by 2080 if the situation doesn't improve.
