Analyzing Dam Locations on Indian Rivers

Let's carefully examine each statement about the location of the dams on the specified rivers to determine which ones are correct.

Statement i: Alamatti dam is on the Cauveri river.

This statement claims that the Alamatti dam is located on the Cauveri river.

Information check:

• The Alamatti dam, officially known as the Lal Bahadur Shastri Dam, is a hydroelectric project on the Krishna river.
• It is located in North Karnataka, India.

Therefore, statement i is incorrect as the Alamatti dam is on the Krishna river, not the Cauveri river.

Statement ii: Mettur dam is on the Krishna river.

This statement says that the Mettur dam is on the Krishna river.

Information check:

• The Mettur dam is a large dam constructed across the Cauvery river (Kaveri).
• It is one of the largest dams in India and is located in Tamil Nadu.

Therefore, statement ii is incorrect as the Mettur dam is on the Cauvery river, not the Krishna river.

Statement iii: Gandhi Sagar Reservoir is on the Chambal river.

This statement claims that the Gandhi Sagar Reservoir is on the Chambal river.

Information check:

• The Gandhi Sagar Dam is the first of the four dams built on the Chambal river.
• The reservoir formed by this dam is indeed known as the Gandhi Sagar Reservoir.
• It is located in the Mandsaur district of Madhya Pradesh.

Therefore, statement iii is correct.

Summary of Findings

Conclusion

Only statement iii is correct regarding the location of the Gandhi Sagar Reservoir on the Chambal river. Statements i and ii incorrectly identify the rivers for the Alamatti and Mettur dams.
