is situated above the lake and hence worshipped on "Nag Panchami" day at the lake; a Lepcha girl named Nenjo Asha Lham was blessed by the lake goddess and was gifted with a precious gem which was lost, and it is the belief of the local people that the gem is hidden in the lake; the lake water has curative properties and hence permitted to be used only for performing rites and rituals; and with all these legends, the lake is called a "wish fulfilling lake".
