It is located about {{Convert|12|km|mi|abbr=on}} northwest of Dashtak. The purpose of the dam is water supply and river regulation. Upstream of the dam will be the intake for the {{Convert|23|km|mi|abbr=on}} Kouhrang 3 Tunnel which will transfer water northeast to the Zayandeh River for use in major cities like Isfahan.[2][3] Sabir Co. was awarded the contract for the dam's construction in February 2011 and construction began that same year.[4] The diversion tunnels for the dam were completed in March 2013. The project is scheduled for completed in 2015.[5] As of July 2017, the project was not yet complete, though the tunnel was considered 97% finished, and newly allocated funds were expected to allow imminent completion [6]. It is claimed that construction of the tunnel in difficult geological conditions has led to drying up of springs, and the estimated transfer volume has been reduced from 270-300 to 40-130 million cubic metres per year.
