The word "dam" refers to a barrier constructed across a river or other waterway in order to increase water storage and control its flow. Dams can be used to generate hydroelectricity or to supply water for irrigation, drinking, and other uses. They are typically constructed using concrete or earth and can vary greatly in size, from small dams that block streams to massive structures that span entire valleys. The word "dam" can also refer to a mother animal's offspring, such as a beaver dam or a duck dam.
