Pond

an artificial reservoir dug to a depth of 3–5 m or created by the construction of dams in the valleys of small rivers or streams or in areas of gorges or gullies. A pond is usually no more than 1 sq km in area; it must have sufficiently steep banks, a slightly sloping bottom, and an erosion-resistant floor. If it is fed by the runoff of river or subsurface waters, the pond will only be filled in the spring by melting snow. Outlets are frequently installed to remove surplus water. In rural areas, ponds are built for irrigation, fish and waterfowl breeding, and the storage of water for various purposes. In cities and recreation areas, ponds are used for fishing, swimming, and other sports.
