Site description The largest freshwater lake in Turkey (max. depth 10 m), 75 km west of Konya. Fluctuating water-levels give a surface area of between 60,000 and 73,000 ha; the lake is fed by mountain streams and several springs. To the north is the Kýzýldað Cedrus forest; to the east the land is under agriculture. Three of the 30 islands are inhabited, others are farmed, the majority are deserted. Narrow reedbeds (Phragmites) fringe the shores with extensive tracts in bays in the east and south-west. Human activities include reed-cutting (`Other' land-use).

Key Biodiversity The site is important for large numbers of wintering wildfowl. Breeding colonies of Phalacrocorax carbo, Pelecanus crispus, Nycticorax nycticorax and Egretta garzetta were formerly present on the islands.
