In general, a dam is any artificial or man-made structure built to stop or restrict the flow of water. Dams help prevent flooding by creating reservoirs, which are artificial lakes that store water. This water can be used to produce electricity (hydroelectric power), provide water for drinking and crop irrigation and provide in-water recreation, such as swimming, fishing and boating.
The Missouri Department of Natural Resources' mission is to ensure dams in Missouri are built, maintained and operated in a safe manner. We provide technical assistance and informational resources to all dam owners. We are also responsible for regulating all nonagricultural and nonfederal dams 35 feet or greater in height, as established by state laws, rules and regulations. Learn more about the various types of dams and the regulations they must follow.
