Usually, during the rainy season, the ponds get filled to the brim. The water is lost due to seepage and evaporation as well as pond bund destabilisation which makes the mud fall into the pond thereby reducing the storage capacity.
To effectively control the issues pointed out, the following techniques can be applied.
- Placing clay at the bottom as well as on the walls of the pond will reduce seepage
- Introducing the following plants in the pond will reduce the evaporation
- The above plants will cover the entire surface of the pond and this way it will reduce the evaporation to the maximum extent.
Vettiver can be planted on the bunds of the ponds which will ensure the soil does not erode/fall into the pond
