RAS question
Which dam is on the Mahi River in Rajasthan?
Correct answer: (D) Mahi Bajaj Sagar Dam.
Mahi Bajaj Sagar Dam is the dam on the Mahi River in Rajasthan.
Explanation
Mahi Bajaj Sagar Dam is built on the Mahi River near Borkhera village in Banswara district, so Mahi is its river. The INDIA WRIS Wiki table for dams in Rajasthan also lists Mahi Bajaj Sagar Dam with its river as Mahi and its basin as Mahi. INDIA WRIS Wiki records its purposes as hydroelectric and irrigation, and the dam supports power generation and irrigation. The dam is 3109 m long, which makes it a major dam in Rajasthan. RAS geography often tests dam-river pairings, so Mahi Bajaj Sagar must be linked directly with the Mahi River.
Why the other options are wrong
- (A) Bisalpur Dam is not on the Mahi; the INDIA WRIS table lists its river as Banas.
- (B) Jawai Dam is not on the Mahi; the INDIA WRIS table lists its river as Jawai.
- (C) Rana Pratap Sagar is not on the Mahi; the INDIA WRIS table lists Ranapratap Sagar Dam on the Chambal.
Concept
RAS geography tests dam-river matching as a recurring pattern because major irrigation and hydropower projects appear as direct factual pairs. Mahi Bajaj Sagar is especially important because it links the Mahi river system with irrigation and hydroelectric use in southern Rajasthan.
