Puttenahalli Lake Yelahanka, Bangalore, Karnataka India

 Puttenahalli Lake is one of the Biggest Lake in Yelahanka. The portion of the Lake beside Ananthapura is fully covered with Grass and weed and hence depletes the water storage. The point where a Bridge is constructed on the Doddaballapura Road dividing the lake, weeds are grown and garbage is being dumped into the lake, thereby choking the lake. The stretch of this lake is foul smelling giving enough indications that "untreated" sewage is being let out into this lake, which should stop.
