- Persian Daryācheh-ye OrūmiyyehShallow, saline lake, northwestern Iran.The largest lake in the Middle East, it covers an area that varies from 2,000 to 2,300 sq mi (5,200 to 6,000 sq km). It is about 87 mi (140 km) long and 25–35 mi (40–55 km) wide, with a maximum depth of 53 ft (16 m). There is a cluster of about 50 tiny islands at its southern part. Fed by three rivers, it has no outlet. It has been protected since 1967.
* * *Persian Daryācheh-ye Orūmīyeh,lake in northwestern Iran that is the largest lake in the Middle East. It covers an area that varies from 2,000 to 2,300 square miles (5,200 to 6,000 square km). Like the Dead Sea, it is remarkable for the extreme salinity of its waters. Since 1967 it has enjoyed the status of a wetland protected region, and efforts have been made by the Iranian government to increase its wildlife.The lake lies in the bottom of the large central depression of the Azerbaijan region in northwestern Iran, at an elevation of 4,183 feet (1,275 m) above sea level. The basin is surrounded by mountains in the west and north, by plateaus in the south, and by plateaus and volcanic cones in the east. The lake is about 87 miles (140 km) long and 25 to 35 miles (40 to 55 km) wide, with a maximum depth of 53 feet (16 m). In its southern portion there is a cluster of about 50 tiny islands. The shoreline varies with the lake level; when the water is high, it extends into large salt marshes to the east and south. The lake's shores are largely uninhabited.The governing factor of Lake Urmia's hydrography is its lack of an outlet. It forms the dead end of a large drainage system that covers an area of about 20,000 square miles (52,000 square km) and is subject to great seasonal variation. The main affluents are the Talkheh (Ājī) River in the northeast, which gathers the melted snows from the Sabalān and Sahand massifs, and the twin rivers Zarīneh (Jagātu) and Sīmīneh (Tatavi) in the south.The volume of water discharged into the lake by these rivers varies considerably during the year: during the spring the Talkheh River and Sīmīneh River may each discharge about 2,000 cubic feet (57 cubic m) per second, while the rate drops to only 130 or 60 cubic feet (3.7 or 1.7 cubic m) per second in the dry summer. This variation causes the lake itself to rise and fall, fluctuating by 2 to 3 feet (0.6 to 0.9 m). In addition to seasonal variations, there are also longer periods of fluctuations, lasting from 12 to 20 years, with water-level fluctuations of 6 to 9 feet (1.8 to 2.7 m).Because Lake Urmia's waters have no outlet, they are highly saline. The lake is one-fourth as salty as the Dead Sea, with a salt content ranging from 8 to 11 percent in the spring to 26 or 28 percent in the late autumn. The main salts are chlorine, sodium, and sulfates.Organic life in the lake's waters is limited to a few salt-tolerant species. Copious algae provide food for brine shrimp and cause a bad smell along the lake's shores. There are breeding populations of sheldrake, flamingo, and pelican, as well as migratory birds.
