Puttenahalli Lake is an iconic lake located in JP Nagar, Bengaluru and is one of the first few lakes revived through citizens action. Its rejuvenation inspired many citizens to form alliances and save more lakes in Bengaluru. It demonstrates that effective action by citizen groups can revitalise the civic culture, improve the nature of public discourse and generate the political will necessary to address pressing problems.
Puttenahalli Lake was filled with solid waste, wastewater and storm water runoff frog residential areas nearby in addition to construction debris. The lake's rebirth began in the year 2010, when a group of concerned citizens came together and formed the Puttenahalli Neighbourhood Lake Improvement Trust (PLOT). In collaboration with Bruhat Bengaluru Mahanagara Palike (BBMP), the trust helped bring the lake back to life through a series of interventions.
