On Saturday also, water was released from the barrage following heavy rains, the official said.
The water discharged from Hathni Kund Barrage -- which provides drinking water to Delhi -- normally takes 72 hours to reach the capital, the official said. "An advisory has been issued by the department regarding the water level and the concerned agencies have been alerted. The situation is being closely monitored," the official added.
Delhi too has witnessed rainfall since Saturday, with the Ridge observatory receiving 65.8 mm rainfall in 24 hours till 8.30 a.m. on Sunday and more rain predicted by the India Meteorological Department.
Hundreds live along the banks of the Yamuna, and they will be moved to safer places once the water level touches the "warning mark".
