The Yamuna's water level remained above the danger mark of 205.33 metres in Delhi on Wednesday. The danger mark was crossed on Tuesday following torrential rain in the river's upper catchment areas over the past two days. The Yamuna system's catchment covers parts of Uttar Pradesh, Uttarakhand, Himachal Pradesh, Haryana, Rajasthan, Madhya Pradesh and Delhi.
The development triggered flood fear but officials said the probability of a flood-like situation again in Delhi is very low.
The drone visuals showed the current situation around Old Yamuna Bridge (Loha Pul) is worrisome. The water level at the Old Railway Bridge crossed the warning mark of 204.50 metres at 3 pm on Tuesday and rapidly rose to 205.39 metres at 10 pm, said to a Central Water Commission official.
"However, the river may not swell to the evacuation level of 206 metres in Delhi unless the hilly region receives more rain," he said.
The flow rate at the Hathnikund barrage in Haryana's Yamunanagar district stood around 27,000 cusecs at 9 pm -- considered moderate during the monsoon season.
An official of the Delhi government's irrigation and flood control department said low-level flooding may occur at a few places along the river but a grave situation is unlikely.
At least 56 people have been killed in Himachal Pradesh as rain wreaked havoc in the hill state since Sunday. Torrential rain also ravaged Uttarakhand over the past two days, destroying buildings and causing landslides that breached the national highways to Badrinath, Kedarnath and Gangotri shrines.
Most of the rivers are overflowing due to the rain. The Ganga is flowing above the danger mark in Tehri, Haridwar and Rishikesh. The Alaknanda and the Mandakini are flowing above the danger level in Rudraprayag, Srinagar and Devprayag, the disaster control room in Uttarakhand's Dehradun said.
Delhi flood
In mid-July, Delhi faced unprecedented flooding due to heavy rainfall in the national capital and the Yamuna river's upper catchment areas. The Yamuna swelled to a record 208.66 metres on July 13, breaching its previous record and penetrating deeper into the city than in more than four decades.
Over 27,000 people were evacuated during the floods with the losses incurred in terms of property, businesses and earnings running up to crores of rupees.
The river flowed above the danger mark of 205.33 metres for eight days on the trot, starting July 10.
Experts attributed the flooding in Delhi to encroachment on the river's floodplain, extreme rainfall within a short span of time and silt accumulation that has raised the riverbed.
