The Chenab River is one of the biggest western tributaries of the Indus River system and contributes to an important part of India-Pakistan water resources. The river was referred to as Chandrabhaga in ancient texts and Asikni in the Rigveda, and is formed by the merging of Chandra and Bhaga rivers at Tandi in Lahaul and Spiti district of Himachal Pradesh. The Chenab has its source in the glaciers around Baralacha La Pass in the Himalayas, travels through Himachal Pradesh and Jammu and Kashmir before joining the river Indus across Pakistani territory. The river itself is about 1,200 kilometres long.
Chenab River Origin & Course
Originally referred to as Chandrabhaga in early Indian texts, the Chenab is also known as Asikni in the Rigveda and is formed from rivulets that originate in the upper reaches of Himachal Pradesh. It is formed at Tandi, where Chandra and Bhaga Rivers meet (Tandi is in the Lahaul and Spiti district). The Chandrabhaga River has two headstreams: the Chandra River, which flows out of the Surya Taal Lake near Baralacha La Pass on one side and the Bhaga River from glacial lakes nearby on the other side.
The Chenab rises from Tandi and flows northwards through the deep gorges of Lahaul, entering the Union Territory of Jammu and Kashmir where it traverses the districts of Kishtwar, Doda, Ramban, Reasi and Jammu. It flows through the Punjab plains, then flows into Pakistan and then at last joins the Sutlej, being a tributary of the Panjnad River (of RB) before draining into the Indus River.
