With rains lashing several parts of India, the Madhya Pradesh government decided to release 3.55 lakh cusecs of water from Bansagar dam into Sone river.
But the water release has forced a flood threat over Bihar capital Patna among other cities.
This is because the water release has also led to swelling of the Ganga river.
It is said that the two states are coordinating the efforts to somehow release the water so that the flooding does not happen.
A Water Resource Development official explained that the water released from Bansagar dam takes two-three days in reaching Indrapuri barrage built across Sone river in Rohtas district.
Materials for flood fighting have been stored at places which may be affected by the increase of water level of rivers.
The officials have been asked to keep a strict vigil and remain alert to tackle any situation.>
