We often confused with the meanings and connotations of the term Dam and Reservoir. Actually, both are different in their meanings. From the evolution of mankind, human has been constantly struggling to harness the flow of water so that they can supply right amount of water to the right places. For that matter, human create dams and reservoir all around the river to control the flow of the river and to store water for various purposes.
Difference between Dam and Reservoir
Dam is created as a barrier that stops or restricts the flow of water or underground streams. Whereas, Reservoir is an open-air storage area (usually formed by masonry or earthwork) where water is collected and kept in quantity so that it may be drawn off for use.
