Situ Gintung (Sundanese, Lake Gintung) was an artificial lake near to the town of Cirendeu in Tangerang District, Indonesia. It was formed by a dam up to 16 metres (52 ft) high which was built by Dutch colonial authorities in 1933. The dam failed on 27 March 2009, draining the lake, with resulting floods killing at least 100 people.
