- Reservoirs: There are numerous reservoirs in South India created by damming rivers or streams. These reservoirs serve multiple purposes, including irrigation, flood control, and hydroelectric power generation.

- Groundwater: Groundwater is an important source of water in South India and is used for drinking, irrigation, and industrial purposes. However, over-extraction of groundwater has led to declining water tables in some regions.

These freshwater sources are vital to the people and ecosystems of South India and their preservation and sustainable management are essential for the well-being of the region.
