A mass of standing water which is either artificial or natural and they are usually smaller than the lakes are known as ponds. Ponds that arise naturally usually do so in floodplains which is usually a part of the river system or they can be 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.
Artificial ponds are the most common to natural ponds since they are easily constructed by humans. Digging ponds in the backyard as well as removing mud form existing ponds is a common practice by many farmers all over the world to ensure that they are able to collect enough water during the wet to sustain their farming activities in the future. Other ponds can be 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.
When constructing an outdoor pond at home, there are factors one need to consider. The main thing to ensure during the construction of an outdoor pond is to look for a site that is well drained as well as ensure that there are no underground cables, pipes, sewers or even septic fields in the area. It is also important to ensure that there is an outdoor faucet that shall be used for the refilling of the outdoor pond. Minimizing the growth of algae on the outdoor pond as well as excessive evaporation of the water can be enhanced by providing partial shading to the outdoor pond. 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. The sun and the shade can be balanced depending on the purpose which the pond shall be put to by using plants such as lilies or even use a portable shade screen for shading. Once a hole for the outdoor pond has been dug, it should be lined well with a suitable outdoor pond liner. Edging of the pond perimeter or even placing some stones should be done once the outdoor pond has been filled with water.
