[4][5] This river takes its source in the heights of the current commune of Beni Amrane in the Khachna Massif which shelters the peak of Bouzegza Mount [ar].

[6][7] At an altitude of 590 meters above sea level near the villages of Beni Khelifa and Azela, Oued Meraldene is born to take its course on a river bed that juts out into the current town of Thénia.

[14] The Meraldene Dam was built between 1911 and 1913 to provide answers to economic questions related to the continuous supply of drinking water, often so difficult to achieve.

[17] This stored water was intended for supplying machine depots and railway workshops in the city of Thénia concurrently with the direct intake 300 meters upstream.

[19] Its final acceptance was made with the dam full, with all the conditions that were met such as the connection of electricity to operate its pumps.
