====Depth====

The water depth is usually 30 cm at the shallow end and 1 metre at thedeep the deep end (figure 6). The pond can be deeper than this if the pond is used as a water reservoir in the dry season. It is important that the water can be completely drained for harvesting.

===Field experiences===

In India and elsewhere larger dams or bunds were traditionally built to create ponds or ‘tanks’ to store water. Water seeps from these ponds into fields of crops and every so often the pond is de-silted and the silt used as a fertiliser. Although there has been a decline in these ponds, there are some places where they are being revived.
