Thulagi glacier is located in the catchment area of the Marshyangdi River basin in Nepal.

A study by KfW, Frankfurt and the BGR (Federal Institute for Geosciences and Natural Resources, Germany), in cooperation with the Department of Hydrology and Meteorology of Nepal have identified it as a potentially dangerous glacier due to possibility of outburst of the lake created by the glacier.

[1][2] Thulagi glacier feeds the Thulagi and Dona lakes.

Thulagi Lake is located southwest of Mt.

From 1991 to 2016, the glacier has retreated at a rate of 30 m/year.
