It is a repository close Kodaikanal town in Dindigul locale of Tamil Nadu, South India. It is at the old site of "Post Hamilton", in the upper Palani slopes. The lake, made by a dam with conduit outlets, is a piece of a micro– watershed improvement venture. Periyakulam town, 18.7 kilometers 11.6 mi to the SE, gets its open drinking water from the lake. The lake's water quality is excellent. There was initially a bog here known as the Berijam overwhelm.
The past presence here of a vast lake, proof of which was unmistakable close-by, was first recorded in 1864 by Colonel Douglas Hamilton of the 21st Regiment of the Madras Native Infantry. No composed record or even nearby legend in regards to the presence of this old lake survives. Be that as it may, in light of noticeable hints of its shoreline which still stayed in 1906, it probably been almost 5 mi 8.0 km long, up to 3,960 ft 1,210 m wide and up to 70 ft 21 m profound. It was clearly shaped by the side of a slope descending into a valley which slants northwards, and damming up the stream which hurried to the Amaravati River at its base.
