Lake Merzbacher (Kyrgyz: Мерцбахер көлү) is a moraine glacier lake located in east Kyrgyzstan between the north and south Engilchek Glaciers in the Tien Shan Mountains.[1] It is often called the "Disappearing Lake" because it drains every year as the ice melts, often causing a glacial lake outburst flood.[2] The lake was named after a German explorer, Gottfried Merzbacher, who led an expedition in the area in 1903.[1][3] An ice dam prevents the lake from draining through the majority of the year. However, when a hole finally melts through the dam, the lake drains within three days.[3] When this happens, the lake's discharge can be up to 1000 m^3 a second which causes destruction of infrastructure and creates major flooding downstream.[1] It goes through this cycle of appearing, expanding and then draining annually.[3]
