This lake is regarded to be the highest lake in the world which is 83 meters higher in altitude than the Tilicho Lake the previous highest lake in the world known so far. However, the officials have not taken out the formal data about it. The length of the Lake is about 1.5 km and 600 meters in width. The local area is known as Singar (in the local language, it means the grazing meadow of yak and sheep), so the locals have given the name of the Lake as Singar.
