"The water level in the Yamuna has risen to 205.94 metres above the danger mark on Saturday morning," an official at the Delhi flood control room said.
About 38,430 cusecs of water is released from Haryana, he said.
"The water level is likely to rise further during the day and after breaching 206 metres mark, it is expected to stay constant. There is nothing to panic about as all arrangements are in place to handle the situation," the official said.
The rise in water level led to flooding in low-lying areas of Usmanpur, Shastri Park, Geeta Colony, Bhajanpura and Yamuna Colony.
Nearly 1,500 people living in low-lying areas were evacuated and shifted to relief camps.
"The Delhi government is fully geared up to meet any situation of flood due to increase in water level in Yamuna. About 150 technical staff members are monitoring the level of the river," the official said.
