塔里木河
The western part of Aksai Chin region is drained by the Tarim River. The eastern part of the region contains several small endorheic basins. The largest of them is that of the Aksai Chin Lake, which is fed by the river of the same name. The region as a whole receives little precipitation as the Himalayas and the Karakoram block the rains from the Indian monsoon.
