The Kouhrang 3 Dam (سد کوهرنگ ۳, also known as Birgan dam بیرگان) is an
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 was 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.
