What is a dam?
Dams are man-made or artificial barriers (earth or combinations of earth and other materials) usually constructed across a stream channel to impound water. Dams provide a range of economic, environmental, and social benefits, including recreation, flood control, water supply, hydroelectric power, waste management, river navigation, and wildlife habitat.
Dams are typically provided with spillway systems constructed of non-erosive materials such as concrete or rock to safely pass a broad range of flows over, around or through the dam.
Dams are typically constructed with a drain or similar mechanism to control water levels in an impoundment for normal maintenance or emergency purposes.
