A tiny lake, picturesquely set amid hills, it is dotted with several islets approachable by a boat. Of particular interest, are strange rock formations around the lake. Especially notable is the Toad Rock, which looks like a real toad about to jump into the lake.

It is the only artificial lake in India, that is1200 meters above sea level.
