It starts in the vicinity of Lake Rakshastal and the Tibetan Plateau, flowing southwestward, entering Himachal Pradesh (India) through the Shipki La pass. It goes through Punjab, where it is a vital lifeline for agriculture, supplying water via the Indira Gandhi Canal system, and finally travels into Pakistan before merging with the Chenab River to create the Panjnad. Sutlej River: 1,450 km (894 mi) in total length. Highly useful for irrigation, hydroelectric power, and water supply for northern India and Pakistan. It is a major source of water for the Bhakra Nangal dam and is also of great help in Regional development and agriculture.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Sutlej River System

style=\"font-weight: 400\"><span style=\"font-weight: 400\">In its upper course before entering the Himalayan region, it is known locally as Langqen Zangbo.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The river has been nurtured by high-altitude glacial and snow-fed sources of the Trans-Himalayan region.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Originating in Tibet, it flows southwestward and follows deep, narrow mountain valleys.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It enters India through the Shipki La pass of Himachal Pradesh, thus entering the Himalayan drainage.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Such a region, forming the source area of the Indus River and its tributaries, has high importance for agricultural regions downstream.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It is
