The Vishansar Lake or Vishan Sar (lit.

'lake of Vishnu') is an alpine high-elevation oligotrophic lake,[1] situated near Sonamarg[2] in the Ganderbal district of Jammu and Kashmir, India, at an elevation of 3,710 metres (12,170 ft).

This lake holds great importance for Kashmiri Pandits.

During the summer season, the lake is surrounded by lush meadows, where local shepherds graze their flocks of sheep and goats.

The Vishansar Lake is the source of Kishanganga River,[5] which flows northwards up to Badoab, and then westwards through Gurais, along the Line of Control.
