The Subernarekha River originates near Nagri village (Ranchi district) in the Chhotanagpur plateau of Jharkhand State at an elevation of about 610 m at latitude 23 18' N and longitude 85 11' E. Subernarekha literally means golden line. According to legends, in ancient times, gold was being extracted in the river's bed close to its origination point near Piska village, close to Ranchi. Before falling in the Bay of Bengal, the river flows through Ranchi and Singhbhum districts of Jharkhand, Midnapore district of West Bengal and Balasore district of Orissa.
