Explanation:

The Sutlej river rises near Rakastal (Rakas lake) which is fed by the lake Mansrover in the Tibetan Plateau. The river Sutlej is known as Langqen Zagbo inside Tibet/China. The River Sutlej travels inside the Tibetan Province and then enters India near Shipkilla Pass (Tashigang-village) in Himachal Pradesh and further Sutlej River travels upto Bhakra Dam. The river then flows through Punjab near Nangal before meeting the Beas River. The merger of these two rivers goes on to the India-Pakistan border. The river continues to flow for joining the Chenab River. The combination of the Sutlej and Chenab river form the Panjnad which finally flows into the Indus River. The river Sutlej is a perennial due to large areas of catchment contributing snowmelt. It is estimated that more than 50 percent of the run-off in the Sutlej Rivers is from the snowmelt. The main tributary in India are Ravi and Beas.
