Subarnarekha originates near Nagri village in the Ranchi district and runs through some major industrial towns and cities, i.e., Jamshedpur, Chaibasa, Ranchi, Bhadrak before joining to the Bay of Bengal at Kirtania port in Orissa. This is why it was named Subarnarekha, meaning “streak of gold”. Legend has it that traces of gold were found within the watercourse bed. Even now, folks hunt for traces of gold particles in its sandy beds. The name could be a combination of 2 words which means gold and line/ streak in Indian languages. According to the tradition, gold has been well-mined close to the origin of this watercourse in a very village named as Piska close to Ranchi.
