Puttenahalli Lake (Yelahanka)

Puttenahalli Lake, located in Yelahanka, a suburb of Bangalore, India, is a restored freshwater lake. Originally neglected and heavily polluted, it was revitalized through community efforts and now serves as a significant urban wetland and bird sanctuary. The lake's restoration focused on de-silting, removing invasive weeds, creating islands for bird nesting, and building a walking path around the perimeter. It is a crucial habitat for a variety of resident and migratory bird species, including herons, egrets, kingfishers, and ducks. The lake's management is often a collaborative effort between local residents, the BBMP (Bruhat Bengaluru Mahanagara Palike), and various environmental organizations. The success of Puttenahalli Lake's restoration has made it a model for similar lake revival projects in Bangalore and other urban areas facing environmental challenges. Public access is generally permitted, allowing visitors to observe the birdlife and enjoy the green space.
