Khalti Lake (Urdu: خلتی جھیل, Khowar: خلتیو چھت) is situated in Gupis-Yasin District, the westernmost part of the Gilgit–Baltistan region and northernmost territory of Pakistan.

This lake is an important source of fresh water and has a stock of trout.

[2][3] The water is extremely cold which flows directly from surrounding glaciers.

The lake usually freezes in winter season and people can easily walk on it.

Those fishes increased in number and reached almost every part of Gupis Valley.
