About Kasavanahali Lake (Sarjapur Road)

Kasavanahali Lake, also known as Kasavanahalli Kere, is an urban wetland situated along the rapidly developing Sarjapur Road corridor of Bengaluru. Despite being surrounded by residential neighbourhoods and ongoing urbanisation, the lake provides an important open-water and wetland habitat for a diverse range of birds. The combination of open water, shallow margins, wetland vegetation and surrounding open spaces creates suitable conditions for waterbirds, waders, raptors and terrestrial species. The lake is particularly valuable for observing birds associated with freshwater habitats, including ducks, coots, moorhens, swamphens, herons, egrets, cormorants and ibises. Its relatively accessible setting also makes it a useful site for urban birdwatching, nature education and increasing awareness about the importance of Bengaluru’s remaining wetlands.

The surrounding landscape adds further habitat diversity, allowing visitors to observe birds beyond the waterbody itself. Open areas around the lake provide feeding grounds for lapwings and other ground-foraging species, while trees and vegetation offer shelter and food for resident urban birds. Raptors such as Black Kite and Brahminy Kite can be seen using the area, while species such as Asian Openbill, Oriental Darter and several species of herons and egrets highlight the ecological value of the wetland. With increasing development along Sarjapur Road, protecting the lake’s water quality, vegetation and natural edges is important for maintaining its biodiversity. Kasavanahali Lake demonstrates how urban wetlands can continue to support significant bird diversity when their habitats are protected and managed responsibly.
