 | | A dam (a common Teutonic word, compare to Dutch dam, Swedish and German damm, and the Gothic verbfaurdammjan, to block up) is a barrier across flowing water that obstructs, directs or retards the flow, often creatinga reservoir, lake or impoundment. |
 | | Intended purposes include providing water for irrigation or town or city water supply, improving navigation, generating hydroelectric power, creating recreation areas or habitat for fish and wildlife, flood control and containing effluent from industrial sites such as mines or factories. |
 | | To minimize that erosion (especially with maximum water elevation at the crest), the downstream face of the spillway isordinarily made an ogee curve. |
