When selecting a good place for a pond, an engineer may seek advice from local people, a biologist or an economist. It may be difficult to find an ideal site but it is necessary to look at the available sites before the work on pond building begins – so that it holds water, does not collapse or cost too much and will not waste effort and money.

There are lots of things to think about before finally recommending a site. Think about getting to the pond (maybe with a vehicle): make sure this is easy. Avoid tall trees that block the sunlight or drop leaves. Avoid swampy, marshy or peat soils and try to avoid places that flood frequently. Think about how to stop poaching. Near towns, avoid neighborhood Factories that give out gases, smoke, fly-ash, or organic or toxic outflows.
