A pond is:

• A body of water smaller than a lake. Used for small bodies of water, generally smaller than one would require a boat to cross; Also: garden ponds, engineered treatment features (see treatment pond), and field units in agriculture (for example, "pondfields" for rice or taro culture) and aquaculture.
• Temporary accumulation of water from runoff (ponded water).
• A now obsolete metric unit of force, see kilopond.
