The Purpose of this dam is production of hydro-electric energy, and flood control of upstream flows.
This project was awarded one of the best concrete projects of Iran in 2010, in the eighth concrete day symposium of Iran.
The project was impounded in April 2010 and officially operated in June 2010.
