A mass of standing water which is either artificial or natural and they are usually smaller than the lakes are known as ponds. natural ponds occur in floodplains and are usually a part of the river system as well as can occur where there are isolated depressions that fill up with rainwater over time. Most ponds are very shallow but they also have life in them mostly plants and animals that are adapted to surviving in water. In most cases, there are various factors that will influence the plants and animals contained in a pond such as water level, nutrient level, shading by the trees salinity, the effects experience when animals graze there as well as presence or absence of streams.
Natural ponds are not very common as to artificial ponds that are constructed by humans to serve certain water needs. During the dry season, farmers are likely to dig ponds in their backyards or remove mud from the existing ones to increase their depth so as they can collect adequate amounts of water during the wet season. There are also ponds that are constructed to enhance habitat restoration and for wastewater treatment. Water gardens and water features are also a type of ponds constructed for purposes such as architectural features or for aesthetic ornamentation for landscapes. Other types of artificial ponds constructed are solar ponds that are used for thermal energy storage and fish ponds are used to breed fish for commercial purposes.
There are various factors that one need to consider when setting up an outdoor pond in their homes. On the site where one wants to construct an outdoor pond, one should ensure that the area is well drained and there are no underground cables, pipes, sewers or even septic fields in the area. Having an outdoor faucet will ensure that it is easier to refill the outdoor pond when there is need. One should also look for a location that has partial shading to prevent high temperatures that may lead to excessive evaporation and increased algae growth. Trees should not be used to provide shading and the pond should also be placed near trees since leaves may fall into the pond causing contamination as well as clogging the pond pump. Depending on the use of the pond, one can balance between the sun and some shade that can be obtained from plants such as lilies or even use a portable shade screen. A suitable outdoor pond liner should be used which is laid down after digging a hole. Edging of the pond perimeter or even placing some stones should be done once the outdoor pond has been filled with water.
