Agra Canal headworks, at Okhla barrage, in Delhi, 1871.
The Agra Canal is an important Indianirrigation work which starts from Okhla in Delhi. The Agra canal originates from Okhla barrage, downstream of Nizamuddin bridge. It opened in 1874.
In the beginning, it was available for navigation, in Delhi, erstwhile Gurgaon, Mathura and Agra Districts, and Bharatpur State. Later, navigation was stopped in 1904 and the canal has since then, been exclusively used for irrigation purposes only. At present the canal does not flow in district Gurgaon, but only in Faridabad, which was earlier a part of Gurgaon.
The Canal receives its water from the Yamuna River at Okhla, about 10 km to the south of New Delhi. The weir across the Yamuna was the first attempted in Upper India upon a foundation of fine sand; it is about 800-yard long, and rises seven-feet above the summer level of the river.
