Question 39 from UPSC CSE 2018 - Geography

Question

Which one of the following is an artificial lake?

Accepted Answer

Correct Option: A. Kodaikanal (Tamil Nadu)

Strategy: The strategy focuses on distinguishing between natural and human-made lakes. Kodaikanal Lake is identified as a man-made lake built during the British era, despite its fame as a tourist spot. In contrast, Kolleru, Nainital, and Renuka lakes are all naturally formed. The approach relies on understanding each lake's origin, particularly the artificial nature of Kodaikanal Lake, to determine the correct classification.
