A Natural Reservoir is a naturally occurring storage area for water, such as lakes, rivers, or underground aquifers. These reservoirs play a crucial role in the ecosystem by providing habitats for various species and maintaining the water cycle. They can also help regulate local climates and support agriculture by supplying water for irrigation. Natural reservoirs are essential for human activities as well. They provide drinking water, recreational opportunities, and are often used for hydroelectric power generation. Protecting these natural resources is vital for sustainability and ensuring that future generations have access to clean water and healthy ecosystems.
