Yamuna water level in Delhi crosses danger mark once again at 205.48 metres
Yamuna had fallen below the danger mark of 205.33 metres. The rise in Yamuna water level could be attributed to increased discharge from Hathni Kund Barrage in Haryana and rains in the upper catchment areas, mainly in Himachal Pradesh and Uttarakhand. The discharge from Hathni Kund barrage rose to 3,60,000 cusecs in July and was recorded at 29,973 cusecs on Friday.
One cusec is equal to 28.32 litres per second. Meanwhile, the IMD has predicted light to moderate rainfall coupled with isolated heavy rainfall in some areas of Uttarakhand and Himachal Pradesh till July 24. The Met office has also predicted a risk of low to moderate flash floods in Chamba, Mandi, Kullu, Shimla and Sirmaur districts of Himachal Pradesh.
A rise in the water level of the Yamuna could slow down the pace of rehabilitation of flood-affected people living in low-lying areas of Delhi, leading to a prolonged stay of these families in relief camps. It could also affect the water supply in the national capital soon after it returned to normal on Tuesday. Rising water levels had led to the flooding of a pumping station in Wazirabad, which supplies raw water to the Wazirabad, Chandrawal and Okhla water treatment plants, which account for about 25 per cent of Delhi's water supply.
Delhi Jal Board (DJB) officials estimate that there is a shortage of 10-12 million litres of water per day because some tubewells have been submerged by river floods. The tube well installed in the Palla floodplain supplies about 30 MGD of water to the DJB. (With inputs from agencies)
