A Dam is a barrier that impounds water or underground streams.  Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.

Most of the dams are single-purpose dams, but there is now a growing number of multipurpose dams.  Using the most recent publication of the World Register of Dams, irrigation is by far the most common purpose of dams.  Among the single purpose dams, 48 % are for irrigation, 17% for hydropower (production of electricity), 13% for water supply , 10% for flood control, 5% for recreation and less than 1% for navigation and fish farming.
