Delhi Dam, also known as Hartwick Dam, is an embankment dam on the Maquoketa River 2.5 kilometres (1.6 mi) southwest of Delhi, Iowa that created Lake Delhi. The dam was over-topped and subsequently failed on July 24, 2010 after a period of heavy rain. It was rebuilt in 2016.
The dam and lake are part of the Turtle Creek Recreation Area, and is owned by a local community group.[4]
