Chenab River

  • Source: It rises in the upper Himalayas in the Lahaul and Spiti district of Himachal Pradesh state.
    • The river is formed by the confluence of two rivers, Chandra and Bhaga, at Tandi, 8 km southwest of Keylong, in the Lahaul and Spiti district.
      • The Bhaga river originates from Surya taal lake, which is situated a few kilometers west of the Bara-lacha la pass in Himachal Pradesh.
      • The Chandra river originates from glaciers east of the same pass (near Chandra Taal).
  • Flows Through: It flows through the Jammu region of Jammu and Kashmir into the plains of Punjab, Pakistan, before flowing into the Indus River.
  • Some of the important projects/dams on Chenab:
    • Ratle Hydro Electric Project
    • Salal Dam- hydroelectric power project near Reasi
