====Other considerations====
* Construct during the dry season.
* Fish can be introduced to eat mosquito larvae, while at the same time providing a source of nutrition. Mudfish are a good option as they can survive dry periods in the silt at the base of pond.
* High evaporation rates are common with open water in certain areas, depending on the climate. Evaporation estimates may be higher than the real situation though - land-based pan evaporation measurements usually exceed reservoir evaporation due to the extra energy a pan receives through its sides and bottom. Even so, water lost to evaporation can be considerable. Some ways to reduce this might include:
# Digging deeper to have a larger volume to surface area ratio. The Charco dam from Tanzania incorporates this through hemispherical design. The problem might be greater levels of investment needed with increased depth. Experience digging reservoirs in Sudan using food-for-work showed that the deeper the dam, the higher the food ratio.
# Planting trees around the pond will act as a windbreak, thereby reducing evaporation.

* Experience from South Africa indicates that access to finance seems to be important in allowing farmers to implement ponds.
