Farm ponds

Farm ponds are used as one of the strategies to support water conservation. Much of the rainfall runs off the ground. The run off not only causes loss of water but also washes away precious top soil. Farm ponds help the farmers to store water and to use it for irrigation.

1. Layout of a farm pond

Farm pond is a dugout structure with definite shape and size. They have proper inlet and outlet structures for collecting the surface runoff flowing from the farm area. The size and depth of the pond depend upon the amount of land available, the type of soil, water requirement of farmers and the cost of excavation. The stored water is used for irrigation.


 

2. Advantages of farm ponds

The advantages of farm ponds are:

·           They provide water to growing crops, without waiting for rainfall.

·           They provide water for irrigation, even when there is no rain.

·           They reduce soil erosion.

·           They recharge ground water.

·           They improve drainage.

·           The excavated soil can be used to enrich soil in fields and levelling lands.

·           They promote fish rearing.

·           They provide water for domestic purposes and livestock.

 

3. Limitations of farm ponds

·           Farm ponds reduce water flow to other tanks and ponds situated in lower-lying areas.

·           They occupy a large portion of farmer’s lands.
