Found at an altitude of 3,700 m asl, Tsomgo Lake is one of the 11 sacred high-altitude lakes in Sikkim, notified by the State Government in 2001 as ‘a religious place more than 100 years old’. Besides, teeming with rich floral and faunal species, the wetland receives huge flocks of waterfowl (about 10-15 at one time) which use this site for halting and transit. The factors that threaten this wetland are:
- Widening of the road due to the opening of the Nathula trade route
- Army vehicles parked near the lake, leading to accidental leakage of diesel and petrol into the lake
- Increasing number of tourists and lack of awareness among them and the locals regarding the lake
- Increased garbage accumulation due to careless littering
- Inadequate infrastructure for functional public toilets and the absence of drainage management
