The Yarışlı Gölü ("Yarışlı Lake") is an outflow-free lake of tectonic origin and is mainly located in the district ( İlçe ) Yeşilova in the Turkish province of Burdur . The south-eastern shore area belongs to the Burdur district .
Emergence
Originally it was a lake that was fed by karst springs. It originated in the early Miocene , about 22 million years ago. In the Pleistocene (around 2.5 million years ago) the water level was much higher, as demonstrated by terrace deposits. During the Würm Ice Age around 100,000 years ago, the Yarışlı Gölü was connected to the Burdur Gölü . However, this connection dried up in the course of the Holocene and the lake shrank to its present size and became saline.
geography
It has only a few small streams, the Kümbet, the Yarışlı, the Kirse Pınarları, the Kadınca Suyu and the Başkuyu Çay as tributaries, therefore the size of the lake fluctuates from in winter up to 16 km² to summer with the minimum of due to evaporation 2 km². Since the tributaries partially dry out in the summer months, large salt marshes and tidal flats form, and the lake depth can drop to a minimum of two meters. In hot summers, the lake dries up completely and forms a salty bog. There is no current in the lake.
In the early 1960s, the Gencali Gölü, which was about six kilometers west of the Yarışlı Gölü, drained and the water was directed into the Yarışlı Gölü, which led to a slight increase in the water level.
There is an approximately 500 m² island near the east bank. On the east bank itself are the ruins of the Phrygian city of Tymbrianassus from the 6th century BC.
biology
The lake's water contains high concentrations of sodium phosphate , sodium chloride, and sodium sulfate . Only at the mouth of the stream is there dense vegetation, otherwise halophyte plants predominate . The Mediterranean fish (Aphanius chantrei) , a small, approximately 7 to 10 cm long fish, which is economically irrelevant, lives in the brackish water area at the mouth of the stream .
The lake plays an important role as a resting place for many species of birds. The white-headed rudder duck (Oxyura leucocephala) , one of the most endangered duck species in the world, winters here . The rusty goose (Tadorna ferruginea) and numerous flamingos (Phoenicopteridae) also spend the winter here or rest here on their way to their winter quarters. Despite the supraregional importance as a bird resting place, the government rejected several applications for designation as a bird sanctuary.
