Tuz Gölü
Ankara is mostly in the Central Anatolia region, and partly in the Black Sea region. Ankara has mountain forests to its north, and the dry plain of Konya to its south. The province is irrigated by the Kızılırmak and Sakarya River systems, the Sarıyar reservoir and many natural lakes and pools. 50% of the land is used for agriculture, 28% is forest and another 10% is meadow and grazing land. Lake Tuz, the second largest lake in Turkey, partly lies in the Şereflikoçhisar district of the province. The highest point of the province is the 2,015 meters tall Işık Mountain in the Kızılcahamam district.
