Lake Merzbacher is a moraine glacier lake located in east Kyrgyzstan between the north and south Inylchek Glaciers in the Tien Shan Mountains. It is often called the "Disappearing Lake" because it drains every year as the ice melts. The lake was named after a German explorer, Gottried Merzbacher, who led an expedition in the area in 1903. 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. When this happens, the lake's discharge can be up to 1000 m3 a second which causes destruction of infrastructure and creates major flooding downstream. It goes through this cycle of appearing, expanding and then draining annually.
