Lake Urmia is an endorheic salt<br />

lake in Iranian Azerbaijan, Iran and<br />

near Iran's border with Turkey.The<br />

lake is between the provinces of<br />

East Azerbaijan and West<br />

Azerbaijan in Iran, and west of the<br />

southern portion of the Caspian<br />

Sea. At its full size, it was the<br />

largest lake in the Middle East and<br />

the sixth largest saltwater lake on<br />

earth with a surface area of<br />

approximately 5,200 km² (2,000<br />

mile²), 140 km<br />

(87 mi) length, 55 km (34 mi)<br />

width, and 16 m (52 ft) depth.[5]<br />

The lake has shrunk to 10% of its<br />

former size due to damming of the<br />

rivers that flow into it and<br />

pumping of groundwater from<br />

the area.<br />

Lake Urmia, along with its once<br />

approximately 102 islands, are<br />

protected as a national park by the<br />

Iranian Department of<br />

Environment.<br />

long cores from Lake Urmia has<br />

revealed a nearly 200 kyr record of<br />

vegetation and lake level changes.<br />

The vegetation has changed from<br />

the <strong>Art</strong>emisia/grass steppes during<br />

the glacial/stadial periods to oakjuniper<br />

steppe-forests during the<br />

interglacial/interstadial periods.<br />

The lake seems to have had a<br />

complex hydrological history and its<br />

water levels have greatly fluctuated<br />

in the geological history. Very high<br />

lake levels have been suggested for<br />

some time intervals during the two<br />

last glacial periods as well as during<br />

both the Last Interglacial as well as<br />

the Holocene. Lowest lake levels<br />

have occurred during the last<br />

glacial periods.<br />
