Karambar Lake (also known as Qurumbar Lake) is a high altitude lake located in Ishkomen, a Tehsil of District Ghizer in Gilgit–Baltistan, near the boundary of Khyber Pakhtunkhwa Province of Pakistan. It is the 31st highest lake in the world and 2nd highest in Pakistan at a height of 14,121 feet (4,304 m) and one of the highest biologically active lakes on earth.
The lake is also known as Qurumbar lake in some references and alternately is spelled as Karomber or Karamber.
The lake is located in Ishkoman Valley, a tehsil of Ghizer District in Gilgit–Baltistan. While some other studies by WWF mention the location in Broghil Valley of Chitral, Khyber Pakhtunkhwa Province. The lake is located at a distance of 205 km from Gilgit. Some maps clearly show that the entire span of lake is situated within the borders of Gilgit–Baltistan. In addition to that, the flow of Karambar waters itself dims the confusion about lake’s location as lake flows down towards Ishkoman.
The approximate length of the lake is 3.9 kilometers (2.4 mi), width is 2 km and, average depth is 52 meters (171 ft) .
Karambar Lake is the deepest lake in the valley with a maximum and mean depth of 55m and 17.08m respectively and is spread over a surface area of 263.44 hectares (2,634,400 m2) and discharges into Karambar valley of Gilgit Baltistan.Water clarity level is 13.75 (Secchi Disc Reading), which is highest value ever recorded in the literature of lakes in Pakistan.
