About
The Karaj runs roughly 152 miles (245 km) in length. Its headwaters are in the Central Alborz mountain range, north of Tehran in Alborz Province. It flows south past the city of Karaj, and then flows eastward with its tributary Jajrood River joining in Tehran Province, to flow into the endorheic Namak Lake basin in the Qom Province.
The Amir Kabir Dam is constructed across the river in the foothills of the Alborz mountain range.
