List of rivers of Pakistan
The Zanskar River has two branches of origin. One of them takes birth in Ropshu area and flowing west-ward reaches Zanskar town. The Zanskar Gorge is in the Zanskar region of Indian-administered Kashmir . Its walls are near vertical cliffs up to 600m high.  The Zanskar River is only 5m wide in places.  It provides an access route to the Zanskar Valley, but only in winter when the river is frozen. The other branch of the Zanskar River is formed from the waters of the glaciers of central Zanskar and flowing south-east reaches Padam. From this place it turns to the north and collecting the waters of the Khurna River empties into the Indus River. Another stream called Zora flowing to the north from the southern frontiers, also joins Zanskar river.
