RAS question
Galwa Dam is on which river?
Correct answer: (C) Galwa.
Galwa Dam is on the Galwa River in Rajasthan.
Explanation
Galwa Dam is placed on the Galwa River. The official Central Water Commission reservoir list for Rajasthan has a row for GALWA and gives its river as Galwa, which directly matches option C. The dam is in Jhalawar district and is used for irrigation in the Hadoti region. The key exam trap is the name overlap. In this case it is not merely a local nickname or a basin label; the CWC river column itself records Galwa. That is why the answer is Galwa, not one of Rajasthan's better-known river systems such as Mahi, Chambal or Banas.
Why the other options are wrong
- (A) Mahi is wrong because the CWC row for Galwa Dam names the river as Galwa, not Mahi.
- (B) Chambal is wrong because Galwa Dam is on the Galwa River, not the Chambal River.
- (D) Banas is wrong because the official reservoir listing places Galwa Dam on Galwa, while Banas is a different river option.
Concept
This tests Rajasthan's dam-river mapping, a recurring RAS geography theme because irrigation projects are often asked through direct location and river-pair facts. It also checks attention to lesser-known Hadoti irrigation infrastructure rather than only the major river systems.
