Alaknanda River
Template:Short description Template:Use dmy dates Template:Use Indian English Template:Infobox river
The Alaknanda is a 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;<ref>Template:Cite book</ref> 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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>In Hindu culture {{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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.<ref name=":0">Template:Citation</ref>
The Alaknanda contributes a significantly larger portion to the flow of the Ganges than the Bhagirathi.<ref name=":0" /> The Alaknanda system drains parts of Chamoli, Tehri, and Pauri districts.<ref name=singh>Singh Negi, Sharad (1995).

Religious significance
In ancient Hindu texts, the Alaknanda river has been used synonymously with the Ganges river. In the Vishnu Purana, the Ganges river which surrounds the city of Brahma divides into four and one of rivers is called Alaknanda, which flows south to India.<ref>Template:Cite book</ref>
Five rivers merge with the Alaknanda and are referred to as prayag or 'holy confluence of rivers' and are places of pilgrimage in Hinduism.<ref name=":1">Template:Cite book</ref> These include Vishnuprayag, where the Alaknanda meets the Dhauliganga River, Nandaprayag, where it meets the Nandakini River, Karnaprayag, where it meets the Pindar River, Rudraprayag, where it meets the Mandakini River, and Devprayag, where it meets the Bhagirathi River and officially becomes the Ganges.<ref name="kapadia">Kapadia, Harish (2001).

The Alaknanda also flows through other important places of pilgrimage such as Badrinath and Joshimath.<ref name=":1" />
Recreation
The Alaknanda river is known for river rafting due to its high rafting grade.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
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.<ref>Hydroelectric Projects on Alaknanda River Basin, by South Asia Network on Dams Rivers and People, www.sandrp.in</ref>
