Tsho Rolpa (alsoCho Rolpa) is one of the biggestglacial lakes inNepal. The lake, which is located at an altitude of 4,580 metres (15,030 ft) in theRolwaling Valley,Dolakha District, has grown considerably over the last 50 years due to glacial melting in the Himalayas.[1][2][3]

The lake threatens to burst through its unstable dam, which would threaten the lives and livestock of over 6100 villagers living around theTamakoshi River.[3][4] In 2012, theUNDP reported that an early warning system installed by the authorities in the late 1990s, which became defunct through lack of maintenance, will be replaced by a more modern warning system for glacial floods from the lake.[5][4]
