Gilgit River

Gilgit River flows through various districts including Gupis-Yasin, Ghizer and Gilgit. It originates from Shandur Lake and proceeds to join the Indus River near the towns of Juglot and Bunji. During its course, Yasin River from Yasin Valley and Karambar/Ishkoman River from Karambar Lake in Ishkoman Valley join it. Hunza River is its largest tributary, contributing over half of its mean annual volume. The confluence of Gilgit River with Indus marks the meeting point of three prominent mountain ranges: the Hindu Kush, the Himalayas, and the Karakoram.

The catchment area of Gilgit River is 26,159 km² (10,100 sq mi). Before the confluence of Gilgit River with Hunza River, its mean annual discharge for the period 1981, 2010 at Gilgit Gauging Station is 293 m³/s (10,300 cu ft/s), with a minimum and maximum discharge of 83 m³/s (2,900 cu ft/s) and 868 m³/s (30,700 cu ft/s), respectively. After receiving inflow from Hunza, its mean annual discharge for the period 1981, 2015 at Alam Bridge Gauging Station was 617 m³/s (21,800 cu ft/s), with a minimum and maximum discharge of 66 m³/s (2,300 cu ft/s) and 4,834 m³/s (170,700 cu ft/s), respectively.
