Retention vs. Detention

Two kinds of ponds are often used for flood control and storm-water runoff treatment: wet ponds and dry ponds. Both systems function to settle suspended sediments and other solids typically present in storm-water runoff. Both retention and detention ponds require periodic maintenance.

Retention Ponds: Also known as wet ponds, maintain a pool of water and serve throughout the year and hold storm-water runoff following storms. Retention ponds help keep sediments at the bottom of the holding area. These can be found in scenarios where water from downspouts or storm-water inlets are present nearby.

Detention Ponds: Sometimes called dry ponds, hold water for a short period of time and serve as an important flood control feature. Their purpose is to slow down water flow and hold it for a period of time to help reduce flooding during storms. These are can be found in scenarios where water may pass beneath roadways.
