Lake Burdur (Turkish: Burdur Gölü) is a large saline lake of tectonic origin, positioned at the frontier between Burdur and Isparta provinces, in southwestern Turkey. It is located at around 37°45′N 30°11′E / 37.75°N 30.18°E. It has an area of 250 km2 and maximum depth variously reported at between 50 and 110 m. Water level in the lake fluctuates. Lake Burdur is also an important wetland site for many bird species and is designated a Ramsar site.
Lake Burdur is among the largest and deepest lakes of Turkey, located at the Lake District Region in south-western Anatolia (37°43′351′′ N, 30°10′878′′ E), within a closed basin. Catchment area is 6150 km2. The average depth is 40 m and maximum depth 68 m. Maximum surface area is 140 km2 at 854 m elevation. It is salty and highly alkaline (pH 9.5) and it never freezes.
Lake Burdur is one of the deepest lakes of Turkey. The aquatic plants are not observed in the lake because of the amount of sodium sulphate and chlorine content. Since the lake does not freeze in winter, it serves as a winter refuge for the birds. The ecosystem of the lake is threatened by the presence of an industrial complex and an airport close to the northern shore. The decrease of water levels (because of construction of upstream dams and unknown causes), increasing of sedimentation (from catchment erosion), organic pollution (from food processing and Burdur City raw sewage waste) and inorganic effluent (from a sulphur mine) represent long-term threats to the integrity of the lake. The water level has decreased from 1975 to 2002 due to construction of dams and ponds in catchment basin, resulting in the loss of 27% of the lake area during the period of 27 years. Nowadays the estimated lake area ranges between 140 km2 or 153 km2.
