The Lake Salt  in terms of surface area is  the second largest lake in Turkey.I is In inner Anatolia,at the border of Ankara,Konya and Aksaray.The salt need of Turkey is provided from the Lake Salt.It is 905 meter hight above at the sea level and There is about 3 million population around it.

The Lake Salt has 11.900 km2 rainfall area and it is a closed basin lake,which has not an external flow.It is called as Lake Koçhisar.Nevertheless Its source of nutritions are unfortunately weak.The stream Peçenek from Şereflikoçhisar,The stream Melendiz from Aksaray,İnsuyu,Karasu and Kırkdelik,coming from the South and western bring water to Lake Salt.The average water level of the lake is 40cm and in may it is about 110cm.In august the lake dries largely.Because of the high average of the salt it is possible to see sedimentation of salt.Towards the end of summer it is possible to walk between the saltern pavement and across the coastal.The proportion of sodium chloride is higher than the proportion of magnesium chloride and the proportion of sodium sulfate.

Accumulation of salt in the lake is connected with various factors.The innovation of oligocene formation play an important role in salinisation of the lake.The sedimentation in the salt layer is digged with machines and collected in salines.The Salines Kaldırım,Kayacık and Yavşan were operated by monopoly but in 2005  they were made private.Salt factories in Şereflikoçhisar are the major factor for the economy of Şereflikoçhisar.The Lake Salt and its around were declared as protection area in 2001.The Lake Salt and its around are main breeding regions of flamingo colonies which is called Phoenicopterus rubber,  at the same time they are the second breeding areas of “Anser albifrons”.

The large water area of the lake is an important  wintering area of the water birds in summer. A large number of birds live here in large groups.Birds feed here easily and they swim in the lake even in awfully winters  because around of the lake is desert.So they are relax here.Thanks to the isles and marshes which occurs in the Lake in spring, sunas,avocets,shelducks and pratincoles can confortably  incubate.Furthermore,there is ecologically  sensitive plant communities here.The Lake Salt and the other lakes around it is a living area for the various bird types especially for the flamingos whose generation is endangered.The central part of the lake there are huge incubation colonies for  the flamingos.
