According to the water commission data, the flow rate at the Hathnikund barrage in Haryana's Yamunanagar crossed the one lakh cusec-mark at 9 am on Saturday, oscillating between two lakh and 2.5 lakh cusecs between 10 am and 5 pm. Irrigation and flood control department officials in Delhi said the heavy rain in the river's upstream areas will impact rehabilitation of the affected families in the inundated low-lying areas of the national capital and they may have to stay at relief camps for a longer period.
