Patna: The flood situation in Bihar remained grim on Tuesday with the Lakhandei river breaching its embankment at three places, affecting thousands, officials said.
Lakhandei, swelled by the flood waters of turbulent Bagmati, breached the embankment in over 50 metres near Basantpur and Aurai in Muzaffarpur district.
The flood waters then submerged over 100 villages, affecting nearly one lakh people.
Road and rail communications were disrupted at several places as flood waters submerged roads and tracks.
Officials said that the Ganges, Gandak, Bagmati and Kosi rivers were rising menacingly at several places.
The water resources department has asked people living in low lying areas in six districts including Patna to shift to safer places.
According to the Central Water Commission, the Ganges was flowing 86 cm above the danger mark at Gandhi Ghat in Patna and Sone 81 cm above the red line at Koilwar.
The National Disaster Response Force (NDRF) has evacuated more than 400 people so far.
But the situation is improving in Rohtas, Aurangabad, Arwal and Bhojpur districts as the Sone waters began to fall.
Two days ago, the Sone created havoc among hundreds of thousands of people following a sudden release of nearly 10 lakh cusecs of water from the Bansagar reservoir in Madhya Pradesh and the Rihand dam in Uttar Pradesh.
