I was so fascinated by the rivers, streams and waterfalls which I came across during our trek to Har-ki-dun that I decided to write a separate post on the same.
At Har-ki-dun we camped near a small stream called Maninda nallah which originates from Maninda lake. The stream meets another stream flowing from the Jumdhar glacier and flows towards Osla village. The locals refer to it as Har-ki-dun nallah.
Just before entering the village, an another stream from the Runisara Lake which is known as Ruinsara nallah joins the Har-ki-dun nallah and from that point onward the stream is known as Supin river. While walking upwards from Osla we saw a huge waterfall on our right which carries more water into the river. There were at least 4 distinct waterfalls that we came across between Osla and Har-ki-dun besides many streams which we crossed during the trek.
The Supin river then flows downwards via Osla, Seema, Gangarh, Taluka and Sankri towards Naitwar. At Naitwar, the Supin meets an another river called Rupin from north. There is a popular trek called Rupin-Supin trek which provides a chance to trek alongside both the rivers. From Naitwar, the river is known as Tons which finally meets the Yamuna near Kalsi. I came to know that the Tons carries more water than the Yamuna and is known as one of the major perennial Indian Himalayan river.
Naitwar is the entry point to Govind Wildlife Sanctuary and a forest department office at Naitwar provides the necessary permits to explore the area. We paid Rs. 1200/-(Rs. 50/- per person per day) to collect our permit for the trek.
These names and details are collected from the locals and our guide. When I saw the details on Google map, the river Supin is only mentioned as Tons. The river is also popular for rafting. On our entire trek from Sankri till the Jumdhar glacier front and back, we drank water from the many tiny streams which finally culminate to become one of the most important rivers of North India- the Yamuna.
The road from Naitwar till Mori goes by the Tons river. It was a beautiful drive and I spotted a Yellow-throated martin by the river side, besides a few species of birds too. Many small towns and villages(like the one in below picture) are situated on the bank of the Tons. The valley of the river is very fertile and agriculture is a major source of income for the people living there.
Quoting T. S. Eliot as he described the journey of a river:
The river itself has no beginning or end. In its beginning, it is not yet the river; in the end it is no longer the river. What we call the headwaters is only a selection from among the innumerable sources which flow together to compose it. At what point in its course does the Mississippi become what the Mississippi means?
*Jumdhar glacier is also known as Jaundhar, Jamdar, Jamdhar etc.
