Purpose
Irrigation: The primary purpose of the Amthane Dam is to provide irrigation facilities to the surrounding agricultural areas. It supports the irrigation of several hundred hectares of farmland, enhancing agricultural productivity and supporting local farmers.
Water Supply: The dam is a crucial source of drinking water for the nearby villages and towns. It ensures a consistent water supply throughout the year, addressing the water needs of the local population.
Flood Control: The dam helps in flood control by regulating the flow of the Amthane River, especially during the monsoon season when the region experiences heavy rainfall.
Environmental and Social Impact
Ecosystem: The creation of the Amthane reservoir has led to the formation of a large water body that supports a diverse range of aquatic life. The surrounding forested areas are home to various species of flora and fauna, contributing to the region's biodiversity.
Displacement: The construction of the dam resulted in the displacement of some local communities. Although efforts were made to compensate and rehabilitate the affected families, there have been complaints regarding the adequacy and timeliness of the support provided.
