It is at the confluence of the Smir and El-lile wadis and has a 17 m (56 ft) saddle dam adjacent to the main dam. The primary purpose of the dam is water supply to the city of Tetouan, 12 km (7.5 mi) to the south. The dam was completed in 1991. The reservoir impounded by the dam has been designated as part of a Ramsar site since 2019.
