Here is your short paragraph on Devaprayag:
The Ganga is formed by the union of five head-streams which rise in the southern Himalayas in the state of Uttar Pradesh.
Of these, the two main head waters, Bhagirathi and Alaknanda unite at Devaprayag, 94 kilometers above Hardwara, that the river comes to be known as the Ganga.
This site of the junctions forms one of the five holy confluences in the hills and attracts innumerable devout pilgrims every year.
The town of Devaprayag in located almost 30 meters above the water’s edge, on the scarp of a mountain rising about 250 metres behind it.
The banks of the Bhagirathi and the Alaknanda are both composed of hard black rock and the river front at the confluence can be reached from the town by a flight of steps cut into the rock.
