Lake Thulagi as been classified as having a major risk of rupture by ICIMOD. it seems that two GLOFs have already occurred on the lake.
During autumn 2013 GDH studied the moraine dam and the banks of the lake in order to map the risks. Today the risk of rupture appears to be very limited.
However, due to the recent earthquakes that have hit Nepal in April and May 2015 it is possible that the likeliness of a rupture has increased.
The human and economic vulnerability downstream is very strong: important villages ( some with about 50 houses), a highly touristic circuit and hydroelectric installations. Thus, the water level in the lake must be monitored as the top of the dam remains fragile.
