Which 12 Bihar Districts Are Under Flood Alert as Ganga Breaks 10-Year Record Mark in Patna?

Continuous rain in Nepal and neighboring states has pushed the Bihar flood situation into a full scale emergency in September 2026. Official numbers from the Bihar Disaster Management Department reveals that around 22.42 lakh people are now living through flooded homes, damaged roads, and destroyed crops. 

The Ganga River has already reached a new highest flood level of 50.57 metres at Gandhi Ghat in Patna. The last time Bihar witnessed Ganga reaching the highest water level mark in its capital city was in 2016 with a record of 50.52 metres. 

Water pouring down from Nepal floods in Bihar's feeder rivers has filled up local streams. The inflow of Nepal floods is forcing authorities to put several districts affected in Bihar flood areas on high alert.

"The Ganga at Gandhi Ghat reached 50.57 metres, which is the highest water level we have ever recorded here. Towns and farm areas near the riverbanks need to stay extremely careful," reported the Bihar Water Resources Department in its morning update.

Which Districts are Under Flood Alert in Bihar? 

State agencies have marked 12 riverfront Bihar districts as high-risk flood zones as of now. At the same time weather officials issued a Yellow Alert for 13 northern and central districts to warn people about strong winds, lightning, and heavy local downpours.

Why Water from Nepal Made Bihar Flood Situation Worse

Local rain in Bihar did play a role in recent flooding of Ganga in Patna but the main reason water levels jumped so fast comes from upstream rivers and glacial lakes in Nepal and Uttarakhand.

• When heavy rains hit the hills in Nepal huge amounts of water were released through the Kosi and Gandak dams into Bihar within a few hours.
• Over decades mud and silt coming down from the mountains have settled at the bottom of Bihar's rivers. This makes the river channels shallower. So they hold less water before overflowing.
• Ganga is already overflowing and smaller rivers like the Punpun cannot empty into it. The water turns around and spills straight into streets and fields.

What Government Teams are Doing Right Now

Rescue workers from the national and state disaster teams have moved into the worst-hit areas to help residents get to safety.

1. Boat Rescues: More than 1,400 motorised boats and 37 rescue teams are bringing people out of flooded houses to dry ground.
2. Food and Medical Care: Officials have set up 190 community kitchens and 50 mobile health centers to give hot meals and basic medicine to displaced families.
3. Checking River Banks: Workers are patrolling river walls day and night to fix leaks before the water breaks through into more villages.

Weather reports suggest light rain will continue over the next two days, so local officials are keeping rescue boats ready in low-lying villages
