Subsequently, heavy rains in the upper catchment areas of the Yamuna, including in Himachal Pradesh, Uttarakhand and Haryana, led to the river swelling to record levels. At 208.66 metres on July 13, the Yamuna surpassed its previous record of 207.49 metres set in September 1978 by a significant margin. It breached embankments and penetrated deeper into the city than it has in over four decades.
