The Delhi government issued a flood warning on Sunday as Haryana released more than one lakh cusecs of water into the Yamuna river from the Hathnikund barrage.
The irrigation and flood control department said this was the first warning, with 1,05,453 cusecs of water discharged at 4 pm.
Normally, the flow rate at the barrage is 352 cusecs, but heavy rainfall in the catchment areas increases the discharge. The water from the barrage takes around two to three days to reach Delhi.
Authorities have been instructed to stay vigilant and take necessary action in vulnerable areas. Quick response teams have been deployed to raise awareness and warn the people living near the river embankments, according to the department.
The Delhi government has set up 16 control rooms, including a central control room, to monitor the flood-prone areas and the water level of the Yamuna.
Earlier in the day, the Central Water Commission (CWC) said the water level in the river in Delhi is rising and is expected to surpass the danger mark of 205.33 metres on Tuesday.
According to the CWC's flood-monitoring portal, the water level at the Old Railway Bridge touched 203.18 metres at 1 pm on Sunday. The warning level is 204.5 metres.
The water level is anticipated to rise to 205.5 metres between 11 am and 1 pm on Tuesday, the CWC said.
Northwest India has seen incessant rainfall over the last two days, with many areas in Uttarakhand, Himachal Pradesh, Haryana, Uttar Pradesh and Rajasthan recording "heavy to very heavy" precipitation.
This has resulted in overflowing rivers, creeks and drains that have massively damaged infrastructure and disrupted essential services in Jammu and Kashmir, Himachal Pradesh and Uttarakhand.
Delhi witnessed its highest rainfall in a single day in July since 1982, recording 153 mm rainfall in the 24-hour period ending at 8:30 am on Sunday. Between 8:30 am and 5:30 pm, the city received an additional 105 mm rainfall, exacerbating the situation.
In response to the torrential rains, the Delhi government announced a closure of all schools on Monday and cancelled the Sunday leave of government officials, instructing them to be in the field.
According to the India Meteorological Department (IMD), Chandigarh and Ambala reported a record rainfall of 322.2 mm and 224.1 mm respectively.
The Yamuna river system's catchment covers parts of Uttar Pradesh, Uttarakhand, Himachal Pradesh, Haryana, Rajasthan, Madhya Pradesh and Delhi.
The low-lying areas near the river in Delhi are considered prone to flooding and are inhabited by around 37,000 people.
Encroachments on the river floodplain have occurred over the years, despite the land belonging to the Delhi Development Authority (DDA), revenue department and private individuals.
Last year, the river breached the danger mark twice in September.
