The Göller Bölgesi: Turkish Lakes Region38.0N 30.8E
The Göller Bölgesi (Lakes Region), in the Western Taurus Mountains of Turkey’s Mediterranean Region, has many freshwater lakes.
Eğirdir is the name of a lake (dark blue, left) and of the town situated on the shore of that lake in Turkey. With an area of 482 km2 it is the fourth largest (second largest freshwater) lake in Turkey.
The large, turquoise lake on the right is Lake Beyşehir. It has an area of 650.00 km² and is 45 km long and 20 km wide. It is a freshwater lake, used for irrigation, whose water level often fluctuates.
Scientists from Turkey’s Middle East Technical University have estimated that if the amount of water taken from the lake is doubled, its area will be reduced by one third, and the water level will be lowered by 6-10 m.
As the number of species in a given area is directly related to the area’s size, as a result of this reduction in size, in Lake Beysehir the number of naturally occurring fish species will decrease from 8 to 7, phytoplankton species from 52 to 45, etc.
The smaller turquoise lake above Beyşehir is Lake Akşehir, a tectonic freshwater endorheic lake also used for irrigation. The lake is fed by the Eber Channel, five larger streams from the Sultan Mountains and many smaller streams. The lake salinity increases towards the middle and northern parts due to underground spring waters.
