==Description==

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 [http://en.wikipedia.org/wiki/Floodgates floodgates] or [http://en.wikipedia.org/wiki/Levee levees] (also known as [http://en.wikipedia.org/wiki/Dike_(construction) dikes]) are used to manage or prevent water flow into specific land regions. [http://en.wikipedia.org/wiki/Hydropower Hydropower] and [http://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity pumped-storage hydroelectricity] are often used in conjunction with dams to generate [[electricity]]. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations.[http://en.wikipedia.org/wiki/Dam]
