Manasi River

The Manasi River (, ماناس دەرياسى also called Manas) is in the south of Dzungarian Basin, Xinjiang, China.

Historically, the Manas River crossed a large section of the Gurbantünggüt Desert, terminating in Lake Manas (45.8°N, 85.93333°W); its length then was about 450 km long. However, due to the water diversion for irrigation and other needs, the Manas River's water has not reached the eponymous lake since the 1960s, and the lake has gone dry.

Numerous reservoirs are constructed on the Manas River and connected streams in the Shihezi City-Manas County area, including the Jiahezi Reservoir with the dam at 44.45°N, 86.12083°W. The reservoirs and canals form an extensive irrigation system in the area.
