Imja Tsho (or Imja Lake) is a cold lake made after meltwater start gathering at the foot of the Imja Glacier on the lower some portion of the icy mass during the 1950s. A recent report portrayed this pool of meltwater as one of the quickest developing in the Himalaya. Held set up by a terminal moraine, Imja Tsho compromises downstream networks with the potential for a chilly upheaval flood.

Imja Tsho has been recognize as one of the possibly risky lakes in Himalaya. It is situate at 27° 53′ 55″ N scope, 86° 55′ 20″ E longitude and at a height of 5010 m in the Everest district of Nepal. The catchment of Imja Tsho possesses the northeastern piece of the Dudh Koshi sub-bowl. The lake itself is situate on the lower some portion of the ice sheet at the toe of its mom ice sheets (nose of Imja and Lhotse Shar Glaciers). The Lhotse Shar Glacier streams in a south-westerly course. The Imja Glacier, then again, is arrange in a north-westerly course and has its end at around 5100 m. These two icy masses mix roughly 3.5 km over the end and stream westwards just underneath the journeying way of Imja Tsho.

The lake was first planned as a couple of lakes from the satellite picture taken in 1962. The all out territory of the lakes was around 0.03 square km. With the dissolving of icy masses, the lakes converged into a super-cold lake during the 1970s and it has developed ceaselessly from that point onward. The lake zone expanded to roughly 0.8 square km (796600 sq m) in 2000 with a normal development pace of 0.02 square km every year.

Based on the recently discharged picture of 21 November 2009 on Google Earth, the Imja Tsho has achieved a region of 1.055 square km because of which the development pace of the lake has expanded to 0.025 square km every year from 2000 to 2009. The primer examination has additionally indicate that there has been an expansion of practically 11% in the lake zone contrast with the zone determine base on satellite picture got in October 2008.
