The Hindiya Barrage is a barrage on the Euphrates south of the town of Musayyib in Babil Governorate of Iraq. Located north of the Al-Hindiya District, it was designed by British civil engineer William Willcocks in response to the silting up of the Hillah branch of the Euphrates. Construction of the dam, with a length of over 250 metres (820 ft), lasted between 1911 and 1913. Between 1984 and 1989, a new dam was built several kilometres upstream as a replacement for the Hindiya Barrage.
