Detention basin. A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time.
A river basin is the land that water flows across or under on its way to a river. Just as a bathtub catches all of the water that falls within its sides, a river basin sends all of the water falling within it to a central river and out to an estuary or to the ocean. A river basin drains all of the land around a major river. Basins can be divided into watersheds, or areas of land around a smaller river, stream, or lake. North Carolina is made up of many watershed connected to each other. Within each watershed, all water runs to the lowest point â a stream, river, lake, or ocean.
