The volume of water in the Yamuna River has surged above the danger mark in India's northern Haryana State on Sunday.
As a result, people living in low-lying areas have been evacuated to safer places and this in turn has sent warning signals to the neighboring Delhi State.
The Yamuna River originates from the Yamunotri glacier in the lower Himalayas.
The river travels a total length of 855 miles before merging with the Ganges River at Allahabad.
Heavy downpours across northern India over the past week have overflowed rivers.
New Delhi alone has recorded a total of 25 inches of rainfall this monsoon season.
