Which of the following is a human-made water body created by blocking the flow of a river or stream?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Reservoir.
A reservoir is an artificial lake created by constructing a dam across a river or stream to store water. These water bodies serve various purposes, including irrigation, drinking water supply, hydroelectric power generation, flood control, and recreation. Unlike natural lakes, reservoirs are engineered systems designed to regulate water flow and ensure water availability during dry periods or high demand, especially in regions with seasonal rainfall. Famous examples in India include the Bhakra Nangal Reservoir and Hirakud Reservoir, according to a National Institute of Hydrology resource.
