It has been a year since Delhi witnessed one of the worst flood spells in Yamuna after four and half decade. The unusual deluge in river on July13, 2023 breached the highest flood level (HFL) 207.49 meter at Old Delhi Railway Station (DRS) attained on September 6,1978 by 1.17 m margin and set 208.66 m as new HFL.

Apart from severely impacting thousands of people in the city, the July 2023 Yamuna flood caught the concerned govt agencies responsible for flood mitigation by surprise and exposed the way city planners particularly DDA, NHAI have been dealing with river floodplains.

The national capital is witnessing one of the worst flood spells with water level at Railway Bridge breaching the highest recorded 207.49 m of Sept 6, 1978 by 1.17 m. The Yamuna seems eager to reclaim all its relict channel and encroached floodplain areas.

The River has set 208.66 meter as new HFL (Highest Flood Levels) for the site at 18:00 hours on 13 July 2023 which is 1.17 meter higher than the 1978’s HFL. The flood level is receding now.
