What are the different types of detention ponds?
• Dry Detention Basins: Dry detention basins are typically dry depressions in the ground surface, except after a major rain storm when they temporarily fill with stormwater. • Wet Detention Basins: Wet detention basins typically have a permanent pool of water and more wetland plant life. The permanent pool of water allows pollutants such as sediments to settle to the bottom of the basin. • Stormwater Marsh Basins: Stormwater marsh basins are similar to wet detention basins, but contain more wetland plants such as cattails bulrush and sedges.
