The Okhla barrage is a 791 meters or roughly 800-yard long weir across Yamuna River opened in 1874. It also serves as the location of Okhla Bird Sanctuary today. It is situated 10 km to the south of New Delhi and downstream of Nizamuddin bridge at Okhla, where Agra canal originates from it. The top of barrage also serves as the Delhi-Noida carriageway of Kalindi Kunj-Mithapur road. Nearby later-era New Okhla Barrage is 554 meters long.

The Yamuna is the second-largest tributary river of the Ganges by discharge and the longest tributary in India. Originating from the Yamunotri Glacier at a height of about 4,500 m (14,800 ft) on the southwestern slopes of Bandarpunch peaks of the Lower Himalaya in Uttarakhand, it travels 1,376 kilometres (855 mi) and has a drainage system of 366,223 square kilometres (141,399 sq mi), 40.2% of the entire Ganges Basin. It merges with the Ganges at Triveni Sangam, Prayagraj, which is a site of the Kumbh Mela, a Hindu festival held every 12 years.
