Van, Lake

Van, Lake
Salt lake, eastern Anatolia.

The largest lake in Turkey, it covers an area of 1,434 sq mi (3,713 sq km) and is more than 74 mi (119 km) across at its widest point. Its greatest depth exceeds 330 ft (100 m). It is fed by precipitation and meltwater as well as by several small tributaries. It has no apparent outlet, and its brackish waters are unsuitable for either drinking or irrigation.

Turkish  Van Gölü,  

      lake, largest body of water in Turkey and the second largest in the Middle East. The lake is located in the region of eastern Anatolia near the border of Iran. It covers an area of 1,434 square miles (3,713 square km) and is more than 74 miles (119 km) across at its widest point. Known to the ancient Greek geographers as Thospitis Lacus, or Arsissa Lacus, its modern Turkish name, Van Gölü, is derived from Van, or Chauon, the name of the capital of the Urartian kingdom that flourished on the lake's eastern shore between the 10th and 8th centuries BC. Roughly triangular in shape, the lake lies in an enclosed basin; its brackish waters are unsuitable for either drinking or irrigation. The salt water allows for no animal life save the darekh (related to the European bleak, a small soft-finned river fish of the carp family), a freshwater fish that has adapted to a saline environment.

      Lake Van occupies the lowest part of a vast basin bordered by high mountains to the south, by plateaus and mountains to the east, and by a complex of volcanic cones to the west. At some time during the Pleistocene Epoch (10,000, to about 2,000,000 years ago), a lava flow from the Nemrut volcano extended for nearly 37 miles (60 km) across the southwestern end of the basin, blocking westward drainage to the Murat River and thereby transforming the depression into a lake basin without outlet.

      Lake Van is divided into two sections; the main body of water is separated from its much shallower northern extension by a narrow passage. Its shores are generally steep and lined with cliffs; the southern shore is extremely sinuous and eroded. The waters are dotted with islands, including Gadir, the largest, in the north; Çarpanak in the east; and Aktamar and Atrek in the south. The main body of the lake to the south is much deeper than its northern section, with the greatest depths exceeding 330 feet (100 m).

      Lake Van's catchment area exceeds 5,790 square miles (15,000 square km); it forms the largest interior basin of Turkey except for that of the central Anatolian region. The lake is fed by rainfall and meltwater as well as by several tributaries, notably the Bendimahi and Zilan rivers, which flow in from the north, and the Karasu and Micinger rivers, which enter the lake from the east. Lake Van experiences a seasonal variation of its water level of about 20 inches (50 cm) per year. It is lowest during the winter months and begins to rise after the spring thaw. With the arrival of additional water from the melted snows of the surrounding mountains, the lake rises to its highest level in July.

      The lake has three distinct temperature zones in summer, consisting of an upper layer of warm water, a lower region of cold water, and an intermediate transitional layer. During the winter the surface cools quickly; occasionally the shallow northern sector freezes over. Freezing of the entire lake is retarded by its high salinity. The most abundant salts in the lake are sodium carbonate and sodium sulfate.

      A regular passenger boat service plies the lake between the coastal towns; there is a small shipyard at Tuğ on the southwestern shore.
