Yamuna breaches danger mark again
New Delhi, July 23
The water level of the Yamuna in Delhi breached the danger mark again on Sunday following a surge in discharge from the Hathnikund barrage into the river after heavy rain in parts of Uttarakhand and Himachal Pradesh.
Further increase in the water level of the river is expected to impact relief and rehabilitation work in the flood-affected low-lying areas of the capital, officials said.
Revenue Minister Atishi on Saturday said the Delhi Government is on high alert due to discharge of over 2 lakh cusecs of water from the Hathnikund barrage into the river and that some parts of Yamuna Khadar (floodplains) might get inundated if the water level rises to 206.7m.
The river water level had been hovering around the danger mark of 205.33m for the past few days after reaching an all-time high of 208.66m on July 13.
The Central Water Commission’s (CWC) data showed the water level rose from 205.02m at 10 pm on Saturday to 205.96m at 9 am on Sunday.
The India Meteorological Department has predicted heavy to very heavy rain in parts of Himachal Pradesh and Uttarakhand till July 25.
According to the CWC data, the flow rate at the Yamunanagar-located Hathnikund barrage crossed the 1 lakh-mark at 9 am on Saturday and oscillated between 2 lakh and 2.5 lakh cusecs between 10 am and 5 pm. Since then, it has remained between 1.5 lakh cusecs and 2 lakh cusecs.
There have been marginal fluctuations in the water level over the past four to five days amid rain in the upper catchment areas, primarily in Himachal Pradesh and Uttarakhand.
Delhi Irrigation and Flood Control Department officials said heavy rain upstream of Delhi would impact rehabilitation of the affected families in the inundated low-lying areas of the capital and they may have to stay in relief camps for a longer period.
It could also impact the water supply in the city, which became normal only on Tuesday after being affected for four or five days due to the inundation of a pump house at Wazirabad.
The pump house supplies raw water to Wazirabad, Chandrawal and Okhla treatment plants, which together account for around 25 per cent of the city’s supply.
Parts of Delhi have been grappling with waterlogging and flooding for more than two weeks now.
Initially, a downpour caused intense waterlogging on July 8 and 9, with the city receiving 125 per cent of its monthly rainfall quota in just two days.
The consequences of the floods have been devastating, with more than 27,000 people evacuated from their homes.
Experts attribute the unprecedented flooding in Delhi to encroachment on the river floodplain, extreme rainfall within a short span of time and silt accumulation that has raised the riverbed.
