[4] Varian village was originally located on the bed of the Amir Kabir Dam and beside the Karaj River.

It supplies the irrigation demand of over 50,000 hectares (120,000 acres) of farm land near Karaj.

The power plant has been connected to the national electricity network for over 46 years and has a capacity of 90 megawatts.

The lake behind the dam is a touristic attraction while being a natural habitat for rainbow trout.

With its sailing and water-skiing facilities, the dam is a popular weekend summer resort.
