Gandak Water Level Recedes in Bihar After Nepal Flash Floods
Heavy rain and an avalanche-related blockage caused flash floods in Nepal.
The floodwater increased the flow of the Gandak River in nearby Bihar.
Officials opened all 36 gates of the Gandak Barrage to manage the water.
The river level later began to fall, giving some relief to people in low-lying areas.
Rain in Nepal’s Devghat area caused the level to rise again briefly.
No damage to Bihar’s embankments had been reported.
Officials are watching the rivers and warning people in sensitive areas.
The floods in Nepal killed at least 162 people.
