Alborz Storage Dam


Alborz Storage Dam Project is located in 45 km southeast of the city of Babol located in Mazandaran Province and on the River Babolrud and its basin. It is located in 52o 48' of longitude and 36o 14' of latitude.


The studies of the water resources development plan of the Rivers Talar, Babol and Haraz were carried out by Mahab Ghodss Consulting Engineering Co. in 1989. In these studies, Alborz Dam was selected as the optimal alternative. Afterwards, the new dam axes were suggested to Mahab Ghodss Consulting Engineering Co. and a Chinese company in the name of Kanic. The dam construction activities were commenced in 1991 and the last powerhouse unit was brought into operation in 2003.
