Kaushalya river

The Kaushalya river, a tributary of Ghaggar river, is a river in Panchkula district of Haryana state of India.

Origin and route
The Kaushalya river rises in the Shivalik hills on the border of Haryana and Himachal Pradesh State, and flows through Panchkula district and converges with Ghaggar river near Pinjore just downstream of Kaushalya Dam.

The basin is classified in two parts, Khadir and Bangar, the higher area that is not flooded in rainy season is called Bangar and the lower flood-prone area is called Khadar.

Several archaeologists have identified the old Ghaggar-Hakra River with the Sarasvati river, on the banks of which the Indus Valley civilisation developed.
