Imja Tsho has been identified as one of the potentially dangerous lakes in Himalaya. It is located at 27° 53' 55 N latitude, 86° 55' 20 E longitude and at an altitude of 5010 m in Everest region of Nepal. The catchment of Imja Tsho occupies the northeastern part of the Dudh Koshi sub-basin. The lake itself is located on the lower part of the glacier at the toe of its mother glaciers (snout of Imja and Lhotse Shar Glaciers). The Lhotse Shar Glacier flows in a south-westerly direction. The Imja Glacier on the other hand is oriented in a north-westerly direction and has its terminus at about 5100 m. These two glaciers coalesce approximately 3.5 km above the terminus and flow westwards just beneath the trekking path of Imja Tse.
