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.
Q: What is the difference between a retention pond and detention pond? A: A retention pond holds a specific amount of water indefinitely. The pond is designed to have drainage leading to another location to keep the pond from overflowing during heavy rains, but otherwise the pond is intended to always be full. Youâll frequently see these types of ponds in commercial properties or subdivisions, often with decorative fountains in the center.
