The lake is located at a height of 2730 m above sea level. With deep blue waters, the lake is held sacred to the sage Prashar and he is regarded to have meditated there. Surrounded by snow-capped peaks and looking down on the fast flowing river Beas, the lake can be approached via Drang. There is a round, floating island inside the lake, which is a common natural phenomenon found all around the world. It is composed of plant matter in various stages of decomposition, and is held aloft by the oxygen in its plants' roots. The floating land moves in all directions in the lake. The floating land covers 7% of area of lake whereas water is with 93%.

The temple was built in the thirteenth century and legend has it was built by a baby from a single tree. The lake has a floating island in it and it is said to be unclear how deep it is, with a diver not being able to determine its depth.
