According to Wikipedia, a dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as agriculture(for irrigation use), human consumption, industrial use, aquaculture, navigability, hydropower(used in conjunction with dams to generate electricity).
