In which state does the Subarnarekha River originate?

Last Updated:

This question examines an important river-or-lake fact: “Which river is known as the 'Subarnarekha' and is the sorrow of which state?” The correct answer is Jharkhand. The Subarnarekha River (meaning 'streak of gold') is known as the 'Sorrow of Jharkhand' because it causes periodic flooding in the Jharkhand region. The river originates near Ranchi in Jharkhand and flows through Odisha to drain into the Bay of Bengal. The Chandil Dam is built on this river. A river system includes its source, tributaries, distributaries, drainage basin, watershed, channel, floodplain, delta or estuary and final outlet. River behaviour depends on relief, geology, rainfall, snowmelt, sediment load, vegetation and human intervention.

Correct Answer: JharkhandYour Answer: C

Explanation

Correct Answer: Option C — Jharkhand The Subarnarekha River originates near Nagri, close to Ranchi, in Jharkhand. It flows across the Chota Nagpur Plateau, passes through parts of West Bengal and Odisha, and finally enters the Bay of Bengal. Its name means “streak of gold,” traditionally linked with traces of gold found in the river’s sands. - Option A — Odisha: The river flows through Odisha and reaches the Bay of Bengal there, but it does not originate in the state. - Option B — West Bengal: Subarnarekha crosses a short part of West Bengal after leaving Jharkhand; this is not its source region. - Option D — Bihar: The river neither originates in Bihar nor forms part of Bihar’s principal drainage system. Exam Takeaway: Subarnarekha rises near Ranchi in Jharkhand and flows to the Bay of Bengal.

Important Notes

  • Subarnarekha rises near Nagri in the Ranchi area of Jharkhand, on the Chota Nagpur Plateau, and follows a generally southeastward course.
  • The river passes through Jharkhand, West Bengal and Odisha before entering the Bay of Bengal near the Odisha coast.
  • Subarnarekha means streak of gold. The name is traditionally connected with small traces of gold found in the river sands and alluvial deposits.
  • Subarnarekha should not be confused with Damodar. Both drain the Chota Nagpur region, but Damodar joins the Hooghly system while Subarnarekha reaches the Bay of Bengal directly.
  • The Kharkai is an important tributary that joins the Subarnarekha at Jamshedpur. Chandil Dam is built on the Subarnarekha in Jharkhand.
