Satluj River is a major river of the Indus system and originates from Mansarovar lake in Tibet. After travelling approximately 300 km in Tibet the river enters India near Shipkila at an elevation of about 2,530m and continues to flow in Himachal Pradesh through Wangtoo and Kian before reaching Bhakra Dam, which was constructed in early Independence era. The principal tributaries of the Satluj River below Shipkila are the Spiti, Kashming, Baspa, Bhaba, Nogli, Korpan, Nauti, Sholding, Seer, Bharari, Ali and Ghamber Khad. The fall of Satluj from its source to the planes of India is reasonably uniform. However the gross fall of 2180 m in the river bed takes place from Shipkila to Bhakra dam in a length of about 320 km. The valley in the portion from Shipkila to Pooh and from Thopan to Rampur is narrow. However in the reach from Pooh to Thopan and between Rampur (proposed power house site) to Bhakra, the valley is comparatively wide. The bed slope of the river is varying and is flat from Shipkila to Jangi Dam site, steep between Jangi Dam site and Rampur and finally even flatter from Rampur to Bhakra Dam.
