Tang Shemiran (Kangir) Storage Dam Project

Project Purpose / Layout

The purposes of the dam are to utilize the irrigated flow in order to irrigate 2000 hectares of farmland in Dasht Zarrineh plain, supply 5x106-m3 water for industrial consumption, prevent exit of boundary water, create job in the poor regions and to improve the environment.

Geographic Location

The dam site is situated near the city of Ivan in Ilam province. The access road to the dam site is 6.5 km long that branches off from the Sumar road (5 km after Zarneh).
