Kausar Nag or Kausarnag (sometimes alternatively spelled as Konsarnag), is a high-altitude oligotrophic lake located in the Pir Panjal Range in the Kulgam District's Noorabad of Kashmir.The lake is roughly 2 miles long and half a mile at the widest point. The trek to Kausarnag is via the famous waterfall of Aharbal. The lake is located in a valley that is surrounded by peaks on all sides with elevation in excess of 4000 metres above sea level.
Kausar nag has an elevation of 4,000 metres (13,000 ft) above sea level.
In July 2014, a controversy erupted when a group of Kashmiri pandits asked the state government to allow them to proceed for an annual yatra to the lake from the valley side. Pertinently, for the past five years, a yatra was being conducted from Reasi side to the place but managed by the local administration. However,the experts have warned against such moves saying the ecological set up would be disturbed. Moreover, experts and the majority political players are of the opinion that the glacial water bodies are only tourist spots and don’t have any religious significance. This led to protests in the Kashmir Valley, especially in the Kulgam district against the conduct of the yatra.
