Lakes of India: Nature’s Reservoirs and Cultural Jewels

India, with its diverse topography and climatic zones, is home to a rich tapestry of lakes that span across its vast landscape. These lakes both natural and man-made serve not only as vital ecological reservoirs but also as cultural, historical, and recreational landmarks. From the snow-fed alpine lakes of the Himalayas to the brackish lagoons of the eastern coast, The lakes of India are as varied as they are significant.

Classification of Indian Lakes

Lakes in India are broadly categorized into two types:

• Freshwater Lakes: These are primarily found in the Himalayan region and the southern plateau. They serve as sources of drinking water, irrigation, and support aquatic biodiversity.
• Brackish Water Lakes: Found mostly along the coastal regions, these lakes are partially saline and support unique ecosystems.

Additionally, lakes can be natural, formed by geological and climatic processes, or man-made, often constructed by ancient rulers for irrigation, water storage, or aesthetic purposes.
