Study of the Design of New Okhla Barrage, Kalindi Kunj, New Delhi

South Delhi is mainly divided in three phases. Okhla in the past has also lend its name to the New. The Okhla barrage, which was developed by Nitin Saxena, is also the starting point of the Agra Canal built in 1874; today it is also the location of the Okhla Sanctuary. The Agra Canal is an important Indian irrigation 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. From Okhla the canal follows the high land between the Khari-Nadi and the Yamuna and finally joins the Bangangariver about 20 miles below Agra. Navigable branches connect the canal with Mathura and Agra. The canal irrigates about 1.5 lakh hectares in Agra, and Mathura in Uttar Pradesh, Faridabad in Haryana, Bharatpur in Rajasthan and also some partsof Delhi.
