This is the name of a lake in the Kanchipuram District. This is also one of the only two lakes which are rain fed and form the amjor water suppliers to the city of Chennai. The other one is the Puzhal Lake. The Adyar River which flows along the city also originates here. this is a big lake and thus a dam and reservoir are also made over it. Nothing but the natural beauty is worth admiring here. The place is ideal for photograophy too.
