This is a very large tank which is devoid of water during the dry season exposing large area of lake shore studded with small islands of trees and shrubs. This is the southern most location in the country where some of the species which are commonly found in the northern part of the country such as the Collared Dove, Indian Grey Partridge can be regularly seen. It is also a location which is favoured by large flocks of migrant ducks. One could walk on the bund as well as drive passing the main turn to the bund and drive down to the dried up tank shore.  Meals & accommodation is available at the Puttlam Rest House as well as some private hotels.
