As per historical records and ancient Hindu religious texts the river was called Narad Ganga.
Although both the rivers are nearly equal in length, the Eastern branch has a higher volume of water as the first half of its course lies in dense forested regions.
Nayar East rises in the meadows of Dudhatoli in a high altitude valley sheltered by towering mountains of over 10,000 feet.
The river forms an intricate network of riparian systems supporting wild animals and plants in its valley.
Nayar, like a typical non-glacial perennial river of lower Himalayas, is the lifeline to inhabitants of its valley.
At the widest point of Nayar East, i.e the stretch from Syunsi to Gudinda, it has formed a broad and fertile valley.
It is believed that crying or weeping near water bodies such as mountain streams, pools & rivers and the echoing of the sound will attract spirits.
Those incidents have somehow affected the psychology of local folks, and it might be said that these old-wives tales were formed to keep mischievous kids away from the river.
