About Sutlej River

  • It is the longest of the five tributaries of the Indus River.
  • It is also known as "Satadree".
  • Origin: It rises on the north slope of the Himalayas in Lake Rakshastal in southwestern Tibet at an elevation above 15,000 feet (4,600 metres).
  • The Sutlej River is primarily located to the north of the Vindhya Range, east of the Pakistani Central Makran Range and south of the Hindu Kush region.
  • Course:
    • The river enters India by flowing west and southwestwards through the Shipki La Pass in Himachal Pradesh at an altitude of 6,608 metres. 
    • The river then flows through Punjab near Nangal before meeting the Beas River. The merger of these two rivers goes on to form 105 Km of the India-Pakistan border. 
    • The river continues to flow for another 350 Km before joining the Chenab River.
    • The combination of the Sutlej and Chenab Rivers form the Panjnad, which finally flows into the Indus River.

  • Tributaries: It has many tributaries, with Baspa, Spiti, Nogli Khad and Soan River being its main ones.
  • Water from the Sutlej River has been allocated to India according to the Indus Waters Treaty of 1960.
