The Alaknanda is a turbulent Himalayan river in the Indian state of Uttarakhand and one of the two headstreams of the Ganges, the major river of Northern India and a river considered holy in Hinduism. In hydrology, the Alaknanda is considered the source stream of the Ganges on account of its greater length and discharge; ^[1] while, in Hindu tradition and culture, the other headstream, the Bhagirathi, is considered the source stream.

Course

The Alaknanda rises at the confluence and foot of the Satopanth and Bhagirath Kharak glaciers in Uttarakhand. ^{[2] [3]} From its origin, it travels to the village of Mana, meets with the Saraswati River, a right bank tributary, and continues downstream through narrow valleys. It reaches the Badrinath valley, arrives at Hanumanchatti, and meets with the Ghrit Ganga, a right bank tributary. From Hanumanchatti, the river goes to Pandukeshwar and flows through wide valleys and steep terrains. At Vishnuprayag it meets Dhauliganga, a left bank tributary, and travels west to the town of Joshimath. From Joshimath, the Alaknanda crosses the Main Central Thrust near Helang. It then meets with Birahi Ganga, a left bank tributary at Birahi. The river reaches the town of Nandprayag and joins with the Nandakini River, a left bank tributary. At Karanprayag, the Pindar River, a left bank tributary, meets with the Alaknanda River. At Rudraprayag, it meets with the Mandakini River, a right bank tributary. As the Alaknanda flows past Rudraprayag, it enters a wide valley near Srinagar, Garhwal. At Devprayag the Alaknanda River converges with the Bhagirathi River and travels onward as the Ganges River. ^[4]

The Alaknanda contributes a significantly larger portion to the flow of the Ganges than the Bhagirathi. ^[4] The Alaknanda system drains parts of Chamoli, Tehri, and Pauri districts. ^[5]

Religious significance

The Alaknanda is of special interest to the pilgrims who visit the important pilgrimage places in Uttarakhand. The Ganges as Alaknanda rises in the southern Himalayas on the Indian side of the Tibet border with China. On the Satopanth Glacier 6 km (3.73 mi) up from Alaknanda's origin at its snout, the triangular Lake Satopanth is found at a height of 4,350 m (2.70 mi). It is named after the Hindu trinity, Brahma, Vishnu, and Shiva.

Badrinath Rishi Ganga River meet Alaknanda

Badrinath, one of the holy destinations for Hindus in India is located near to the bank of the Alaknanda River. This place is surrounded by two mountain ranges of Nar and Narayan on either sides and Neelkanth peak located at the back of Narayan range.

Panch Prayag

Several rivers in the Garhwal region merge with the Alaknanda at places called prayag or 'holy confluence of rivers'. These are: ^[6]

1. Vishnuprayag, where the Alaknanda is met by the Dhauliganga River
2. Nandaprayag, where it is met by the Nandakini River
3. Karnaprayag, where it is met by the Pindar River
4. Rudraprayag, where it is met by the Mandakini River
5. Devprayag, where it meets the Bhagirathi River and officially becomes the Ganges

Recreation

The Alaknanda river is among the best for river rafting in the world due to its high rafting grade. ^[7]

Dams

There are 37 hydroelectric dams in operation, under construction or planned to harness the energy of the Alaknanda river and its tributaries and generate electricity. ^[8]
