Detention vs retention pond.

Dry detention pond: a pond that will normally not have standing water, except for a short time after a large storm event. Inlet: the mechanism that allows water into the stormwater basin or pond. Usually a pipe, ditch, or swale. Outlet: the structure that controls the rate of release from the pond and the water depth and storage volume in the pond. Retention is primarily provided on the surface through ponds, and underground through tanks, more commonly geocellular tanks. Detention is often provided by detention basins. Retention storage within ponds as well as helping manage flood risk is also useful in providing water treatment. However, there should be upstream components or treatment ... Detention basins are surface storage basins or facilities that provide flow control through attenuation of stormwater runoff. They also facilitate some settling of particulate pollutants. However, basins can also be mixed, including both a permanently wet area for wildlife or treatment of the runoff and an area that is usually dry to cater for flood attenuation.A lot of times retention and detention ponds are built near each other. The detention pond will hold the water up first and help prevent flooding. Water will then slowly drain out into the retention pond where it is held. These ponds also can assist with pollution removal. During periods of heavy rain, the ponds slow water movement.
