Q: What is the difference between a retention pond and detention pond?
Peter – Harrison, AR
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. You’ll frequently see these types of ponds in commercial properties or subdivisions, often with decorative fountains in the center.
A detention pond, or “dry pond,” is a low-lying area that temporarily holds water until the water drains to another location. It is not filled with water all the time. A detention pond is generally used for flood control when large amounts of rain and storm water runoff could cause flash flooding if not dealt with properly.
Poor maintenance of either type of pond can create unpleasant odors, nuisance insects, algae blooms, and an unkempt area. Due to the nature of runoff having exceptional amounts of nutrients, using natural products such as Pond Logic® Eco Boost™ or Pond Logic® Muck Away™ can help control these flash floods of nutrients.
