The Dhauliganga River is a powerful Himalayan river that originates near the India-China border and flows through Uttarakhand, India. It is a major tributary of the Alaknanda River, which later forms the Ganges River. The river is known for its turbulent flow, scenic landscapes, and religious importance.
Origin and Course of Dhauliganga River
The Dhauliganga River originates near the Niti Pass, located at the India-Tibet border in the Garhwal Himalayas. It flows southward for 50 km (30 miles) before meeting the Rishiganga River at Rini village in Chamoli district.
After this, it continues westward for 20 km (10 miles) before merging with the Alaknanda River at Vishnuprayag, near Joshimath. This confluence is one of the Panch Prayags, which are sacred confluences in Hinduism.
Geographical Significance
The Dhauliganga River valley divides two important Himalayan mountain ranges:
Nanda Devi Range (to the left).
Kamet Range (to the right).
This region is rich in biodiversity and is home to rare Himalayan flora and fauna.
Major Tributaries of Dhauliganga River
- Rishiganga River – A key tributary that joins the Dhauliganga at Rini village.
- Girthi Ganga River – Another tributary that contributes to the flow of the Dhauliganga.
These rivers enhance the water volume and power of the Dhauliganga, making it one of the most forceful rivers in Uttarakhand.
