Why is desilting important?
Desilting your dam is important as silt can increase the risk of evaporation, algae blooming in your water supply and reduces the amount of water your dam can hold. This can be especially concerning during drought periods and for farmers. You can also maintain other areas of your dam as well while it is dry.
