The two head streams of the Ganga are Bhagirathi and Alaknanda.......:)

Headwaters of River Ganga:
The River Ganga, also known as the Ganges, is one of the most sacred rivers in India. It originates from the Himalayas and is fed by numerous headwaters. Two prominent headwaters where the Ganga originates are the Bhagirathi and Alaknanda rivers.

Bhagirathi River:
The Bhagirathi River is considered the main headwater of the Ganges. It originates from the Gangotri Glacier in the Garhwal Himalayas at an altitude of around 3,100 meters. The Bhagirathi River flows through the picturesque valleys and gorges of Uttarakhand, eventually meeting the Alaknanda River at Devprayag to form the River Ganga.

Alaknanda River:
The Alaknanda River is another important headwater of the Ganges. It originates from the confluence of the Satopanth and Bhagirath Kharak glaciers near Badrinath in Uttarakhand. The Alaknanda River flows through the rugged terrain of the Himalayas, passing through several important towns and pilgrimage sites. It joins the Bhagirathi River at Devprayag, where the two rivers merge to form the River Ganga.

Conclusion:
The meeting point of the Bhagirathi and Alaknanda rivers at Devprayag is a significant confluence that marks the beginning of the sacred River Ganga. These headwaters play a crucial role in sustaining the Ganges, which holds immense religious and cultural significance in India.
