The lake was created by a massive landslide and sink-hole landslide triggered by a high intensity earthquake in 1911. The phenomena monitoring landslide created the Usoi Dam (650m high), the highest dam systems in the world, either natural or man-made. The lake that formed Maintenance and PAG. 6 behind the dam initially rose at a rate of approximately 75m/year technological adaptation of and drowned the village of Sarez, after which it was named.
