retention pond
Runoff collection pool
A retention pond is an artificial basin designed to collect and hold stormwater runoff, typically found in residential developments, parking lots, and commercial properties.
Unlike detention ponds that release water gradually, retention ponds hold water permanently, allowing sediment to settle and pollutants to break down before water seeps into the ground or evaporates.
The neighborhood retention pond attracts ducks and geese.
