Concept:
- Dams in the chapter are best remembered by pairing each with its river, because the river is usually given in the question.
- Once the river is fixed as the Narmada, only one large dam in Gujarat fits.
Step 1: Recall the major dams paired with their rivers.
The Bhakra Nangal dam stands on the Satluj and Beas, the Hirakud dam on the Mahanadi, the Tehri dam on the Bhagirathi, the Nagarjuna Sagar dam on the Krishna, and the
Sardar Sarovar dam on the Narmada.
Step 2: Apply the state given in the question.
The Narmada passes through Madhya Pradesh, Maharashtra and Gujarat. The question specifies Gujarat, and the Sardar Sarovar project lies in that state.
Step 3: Confirm with the scale of the project.
It is described as one of the largest multi-purpose projects of India, carrying water through a long canal network to the dry areas of Gujarat and Rajasthan. No other dam on this river in Gujarat is of comparable size.
Final Answer: The dam is the Sardar Sarovar Dam, built on the Narmada in Gujarat.
