RAS question
The Bisalpur Dam in Rajasthan is built on which river?
Correct answer: (B) Banas.
Bisalpur Dam in Rajasthan is built across the Banas river near Bisalpur in Tonk district.
Explanation
Bisalpur Dam is on the Banas river, so option B is the answer. The World Bank DRIP-II due-diligence report describes the project as “Bisalpur Dam across Banas river” and, in its salient features table, lists the river simply as Banas. The dam is placed near Deoli in Tonk district. It also matters beyond a map-location fact: it was constructed to create irrigation and drinking-water supply capacity, including supplies for Jaipur, Ajmer and en-route villages, along with irrigation through its canal system. For RAS, the key link to remember is Bisalpur-Banas-Tonk, not Chambal, Luni or Mahi.
Why the other options are wrong
- (A) Chambal is associated with Rana Pratap Sagar and Gandhi Sagar dams, whereas Bisalpur is on the Banas river.
- (C) Luni is an inland-drainage river, while Bisalpur is on the Banas, not the Luni.
- (D) Mahi is linked to Mahi Bajaj Sagar in Banswara, while Bisalpur is documented on the Banas river.
Concept
This tests Rajasthan geography through major river-dam pairings and their public-utility role. Such pairings recur in RAS because they connect physical geography with irrigation, drinking-water supply and regional development.
