The Satluj-This is the principal river of Kinnaur almost dividing the district into two parts. It runs within the Himalayan mountains for about 450 kilometers and the first part of its course is west-north-west. When it enters Kinnaur, it generally takes south-westerly direction. Within the District the length is about 130 km. Its source is supposed to be at a great elevation on the southern face of the Kailash range whence it flows into the sacred lake Rawan Hard. As far as the village of Khab it is almost a razing torrent. At Khab it receives the Spiti river where the bed of stream is still above 2,589 m high from the mean sea level. The Satluj descends from about 3,050 m (the point of its entrance in the district), to 1,220 m at Chaura flowing almost the whole way between narrow cliffs and therefore, there is no open ground worth describing all along its bank.The water of the river is more or less discoloured.Cultivated fields in terraces are generally at considerable height from its banks and thus immune from the turbidity of water which largest in June, July and August. The average discharge is about 2,000 cusecs during the winter and 100,000 cusec during June-July. The tributaries of the Satluj in this district are the Spiti, the Ropa, the Taiti, the Kashang, the Mulgoon, the Yula, the Wanger, the Shorang and the Rupi on the right bank and the Tirung, the Gyanthing, the Baspa, the Duling and the Solding running on the left bank.
