A reservoir is defined as which of the following?

• A. A natural lake formed by rainfall
• B. A place where groundwater collects underground
• C. Behind a dam, river water collects in an artificial lake
• D. A small pond in a park

Answer: (C)

A reservoir is a man-made water storage area created by damming a river, forming an artificial lake. Water is held back behind the dam and stored for uses such as drinking water, irrigation, and generating electricity, and this storage helps with water supply management and flood control. That behind-a-dam, artificial-lake setup is what defines a reservoir, so this description fits best. Natural lakes formed by rainfall aren’t reservoirs, groundwater collects underground in aquifers, and a small park pond isn’t a large water-storage reservoir.
