The swollen Ganga river is threatening to flood Bihar capital Patna.
The river has been flowing well above the danger mark and threatens to inundate settlements on the banks.
Bihar Water Resources Minister Vijay Kumar Choudhary, though, says that there is no need for panic.
"Necessary instructions to prevent the flooding of the city have been given to officials," he told rediff.com.
"The government has already initiated the emergency mechanism to protect Patna in view of rising Ganga following heavy rains in the neighbouring states and some parts of Bihar in last 24 hours," Jawahar Lal, an official of the flood cell of the state Water Resources Department said.
To prevent the river from flowing into Patna, the state authorities have sealed all the openings along the 8.5 km-long Patna town protection wall that was constructed after the floods of 1975
