Yamuna Watch tracks the water level of the Yamuna river at Delhi's Old Railway Bridge (ORB) against the official warning level of 204.50 metres and danger level of 205.33 metres, alongside the discharge from Hathnikund Barrage in Haryana. Under Delhi's Flood Control Order 2026, a three-stage flood warning is activated based on Hathnikund discharge: the first warning at one lakh cusecs, the second at three lakh cusecs, and evacuation measures beyond that. Floodwater takes roughly 36 to 72 hours to travel from Hathnikund to Delhi. Delhi's highest recorded Yamuna flood level was 208.66 metres in 2023. This site is unofficial and indicative; it is not an official flood warning. Always follow the Central Water Commission (CWC), the Delhi Irrigation and Flood Control Department, and the Delhi Disaster Management Authority.
Low-lying and embankment areas along the Yamuna in Delhi that are vulnerable during high water include Yamuna Bazar, Civil Lines, ITO, Rajghat, Nigambodh Ghat, Sonia Vihar, Usmanpur, Garhi Mandu, Shastri Park, Mayur Vihar, Yamuna Khadar, Nizamuddin, Kilokari, Okhla and Batla House. Water levels rise mainly due to releases from Hathnikund Barrage upstream.
