Topuzlu Dam was built in 1750 by Ottoman Sultan Mahmud I (reigned 1730–1754). In 1786, its crest was raised about 3.40 m (11.2 ft) higher by Abdul Hamid I (reigned 1774–1789).[1] The dam is named "Topuzlu" meaning "bulged" due to a bulge-formed central part of the upstream wall side.
The dam is situated just north of Bahçeköy, Sarıyer inside the Bentler Nature Park, which is part of the Belgrad Forest.[2][3]
