Detention Pond

A low lying area that is designed to temporarily hold a set amount of water while slowly draining to another location, or back to the water table. A water detention pond, by definition, detains water. When an area is paved, or covered with a building, water runs off the property much faster than when it is in a natural state. The total amount of discharge is the same, but the discharge happens over a shorter amount of time. A hydrologist will design a water detention pond to temporarily detain the water and keep the runoff to the desired rate. When the rain ends, though, the water detention pond will be empty shortly afterwards.

Not to be confused with:

  • Retention Pond
  • Underground Detention Facilities
