The traditional source of the river is the "Sênggê Kanbab" (a.k.a. Sênggê Zangbo, Senge Khabab) or "Lion's Mouth", a perennial spring, not far from the sacred Mount Kailash marked by a long low line of Tibetan chortens. There are several other tributaries nearby, which may possibly form a longer stream than Sênggê Kanbab, but unlike the Sênggê Kanbab, are all dependent on snowmelt. The Zanskar River, which flows into the Indus in Ladakh, has a greater volume of water than the Indus itself before that point.
