 74% of the Zayandeh Rood dam volume is empty!

Isfahan (IMNA) - According to the information center of the Ministry of Energy and based on the released report, the situation of the Zayandeh-Rood is described as follow: Since late last year, the unprecedented drop in the country's rainfall, and consequently the reduction of water storage in the Zayadeh-Rood dam as an important source of drinking water for the cities of Isfahan, Yazd, Kashan, and the nearby villages, have raised many concerns about the way of supplying the drinking water for these areas in summer.  


The normal volume of the reservoir is about 1 billion and 239 million cubic meters. Currently, the water storage capacity behind the dam has been decreased to 318 million cubic meters that in comparison to the last year, has decrease by 15 %; practically, 74% of this dam is empty.
