It is the easternmost branch of the Indus River. The source of the river is at Lake Rakshastal in Tibet,[1] near Mount Kailas. It flows generally west and southwest through the region of Punjab. The region to its south and east is dry, and is known as the Thar Desert.

In Punjabi, the river's name is written ਸਤਲੁਜ. In Sanskrit, it is शतद्रु or सुतुद्रीSuṭudri. In Urdu, it is written Urdu: ستلج, and Hindi: सतलुज.

In the Mahabharata, the river is named the Satadree.[2] It is also known as the Red River.
