Çubuk-1 Dam

It is located 12 km north of the center of Ankara and was built to control floods and provide drinking water to the city.

Its construction lasted from 1930 to 1936; Mustafa Kemal Atatürk attended its inauguration on November 3, 1936.

[2][3][4][5] It is owned and maintained by the Turkish State Hydraulic Works and was constructed at a cost of 2.32 million TRY.

Hardly used, its reservoir has a normal volume of 1,200 m3 (42,000 cu ft) and surface area of 1 km2 (0.39 sq mi).

Silt accumulation in the reservoir along with raw sewage being dumped upstream halted water supply from the dam in 1994.
