Dhauliganga River
Origin and Course of the Dhauliganga River
The Dhauliganga River originates near the Niti Pass, close to the India-Tibet border in the Garhwal Himalayas. Flowing southward for approximately 50 km (30 miles), it meets the Rishiganga River at Rini village in Chamoli district. From there, it continues westward for another 20 km (10 miles) before merging with the Alaknanda River at Vishnuprayag, near Joshimath—one of the Panch Prayags, the five sacred confluences in Hinduism.
Geographical Significance
The Dhauliganga River valley serves as a natural divider between two prominent Himalayan mountain ranges:
- Nanda Devi Range (on the left)
