Drass River is an important tributary of the
Shigar (South) River, which in turn drains into the
Indus at
Marol. This river originates from the snowy wastes and small glaciers on the northern face of the main
Himalayan range. The water flow of the Drass rises drastically in late summer when it receives a large quantity of water from the melting snow. The river, after a long journey, flows towards the north and merges with the Shigar (South) River.
