Some major floods unleashed in Nepal when mountain lakes fed by melting glaciers burst their banks:
September 1977: An outburst from Nare Lake, below Mount Ama Dablam, kills three people and wipes out several bridges.
June 1980: A flood from overflowing Nagma Pokhari, once a small pond in Hungu Valley near Mount Everest, floods farms and houses along a 44-mile (71-kilometer) stretch of riverbed.
August 1985: An ice avalanche sends Dig Tsho lake water cascading downriver, killing at least five people and destroying farms, a hydropower station and 14 bridges. It also washes away large sections of the Everest trekking trail.
July 1991: Floodwaters from Chubung Lake in Rawaling, central Nepal, kill one person and damage homes and farmland.
September 1998: An ice avalanche hits Tam Pokhari lake, launching a wave over the banks that inundates villages below and kills at least two people. Six bridges and large tracts of farmland are washed away.
