Ganga river system: Tributaries & River valley projects
- It originates from Gangotri glacier near Gaumukh in Uttarkashi district in Uttarakhand. It forms various prayags (confluence of two rivers) as shown below:
- Alaknanda + Dhauliganga = Vishnuprayag
- Alaknanda + Pindar = Karnaprayag
- Alaknanda + Mandakinin = Rudraprayag
- Alaknanda + Bhagirathi = Devaprayag
When Ganga reaches West Bengal, it gets divided into two distributaries called Bhagirathi and Hugli. Damodar river is the tributary of Hugli. The main river goes into Bangladesh where it is first called Meghna and then Padma which then enters Bay of Bengal.
