The water level in the river was recorded at 207.32 metre at 7 pm, which is 2.49 metre above the danger mark of 204.83 metre. The highest water level of 207.49 m in Yamuna was recorded in 1978 when several areas in the city had witnessed flash floods.
Officials said the water level is expected to cross the highest level by midnight tonight. The city government has asked the army to be on alert for helping the civil administration, if required.
The water level in Yamuna has increased primarily due to release of around 11 lakh cusecs of water into Yamuna by Haryana from its Hathnikund barrage in the last three days.
The neighbouring state released around one lakh cusecs of water into the river today.
