Lake Van is the largest lake in Turkey, located in the far east of the country in Van district. It is a saline and soda lake, receiving water from numerous small streams that descend from the surrounding mountains. Lake Van is one of the World's largest endorheic lakes (having no outlet). The original outlet from the basin was blocked by an ancient volcanic eruption. Although Lake Van is situated at an altitude of 1,640 m (5,380 ft) with harsh winters, it does not freeze due to its high salinity except occasionally the shallow northern section.
Lake Van is 119 kilometres (74 mi) across at its widest point, averaging a depth of 171 metres (561 ft) with a maximum recorded depth of 451 metres (1,480 ft). The lake surface lies 1,640 metres (5,380 ft) above sea level and the shore length is 430 kilometres (270 mi). Lake Van has an area of 3,755 km2 (1,450 sq mi) and a volume of 607 cubic kilometres (146 cu mi). The lake's outlet was blocked at some time during the Pleistocene, when lava flows from Nemrut volcano blocked westward outflow towards the Muş Plain. Now dormant, Nemrut Dağı is close to the western shore of the lake, and another dormant stratovolcano, Süphan Dağı dominates the northern Side of the lake.
