This oval-shaped lake is found at an altitude of 3,604 m asl, in the arid zone of Himachal Pradesh also called a ‘cold desert’, in the northwestern Himalayas. The dry hill soil is thick and fertile and the lake thus supports a wide array of floral, as well as, faunal species, contributing to the rich biodiversity of the region. However, Nako is facing the following threats:
- Solid waste left behind by visitors and tourists, particularly non biodegradable materials
- Huge construction activities on all sides of the lake
- Sewage from the Nako village entering into the lake
