Retention basin

A retention basin is used to manage stormwater runoff to prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay. Sometimes called a wet pond or wet detention basin or stormwater management pond, it is an artificial lake with vegetation around the perimeter, and includes a permanent pool of water in its design.
