Dry ponds may include a deep pool in the sediment forebay to minimize scour and sediment resuspension, but the main basin does not retain a permanent pool of water. As a result, contaminants cannot settle between storm events, nor is there dilution of pollutants during storms. Consequently, while dry ponds are effective for erosion and flood control, they may need to be paired with other LID features in a [[Treatment train|treatment train]] to improve water quality beyond the basic treatment level of 60% long-term TSS removal.
