Detention Pond releases water into the drainage system. Retention Pond does not release to a downstream system. Detention pond also refers to dry basins. However, Retention Ponds refer to wet basins. Detention ponds are designed to hold water by the process of underground pipes.

Retention ponds have flow orifices above the pond’s bottom. Operators place the flow orifice at the desired depth level when flooding is not occurring. Similarly, to how detention ponds work, when water levels in a retention pond are higher than the flow orifice, water flows out until the pond reaches its normal level.
