Haryana also released over 400,000 cusecs of water into the river upstream.
Last year, the water level reached 206 metres, leading to the evacuation of people from slum clusters along the river bank.
The Delhi government has said it is fully prepared to tackle any situation.
'We have boats for rescue operations. Relief camps are also being set up in various areas. All the necessary arrangements have been taken care of. Delhi has thousands of people living in low-lying areas near the Yamuna,' said a Delhi government official.
