Bihar Floods 2026: Ganga Breaks Records, Districts Impacted and IMD Warnings

Due to heavy rainfall in parts of northern India as well as their neighboring states, the flood situation in Bihar has worsened. In Patna, the Ganga River has exceeded the highest level of flood water ever recorded leading to the inundation of wide low-lying areas, diara areas, and vital large utility infrastructure. More than 22.4 lakh people in more than 12 districts have been affected by floods.

Emergency alerts have been issued and rescue teams deployed by the Bihar Disaster Management Department and the district administrations leading to the establishment of relief camps. Below is the elaborated account of the water level records, flooded areas, railway services affected, IMD predictions, and the relief operations carried by the government.

Bihar Floods 2026:Ganga River Water Levels Go Beyond 2016 Max Record

According to the Water Resources Department (WRD), there has been significant rise of water level along the main course of Ganga

• Gandhi Ghat (Patna): Ganga at 50.57 meters has set an all-time high, breaking erstwhile record of 50.52 meters set on August 21, 2016. The water level of river Ganga will mean that water is more that 2 meters higher than the danger mark declared by the authorities.

• Pandarak (District Patna): The river level ahs reached 43.92 meters thus breaking the earlier record of 43.73 meters set in August 2021.

• Downstream Alert at Hathidah: As there is vast water influx from above, alerts have been issued for gauging stations in Hathidah, Munger, Kahalgaon and Bhagalpur.

List of Impacted Districts and Population Affected

According to official updates, approximately 22.42 lakh people across 12 key districts are experiencing severe inundation:

Flood-affected Region: Villages, farmland, and the urban fringes at places like Patna, Fatuha, Raghopur, and Bhagalpur are submerged in water, prompting people to seek refuge in safe places.

Other Flooding Rivers: The Gandak (near Dumariaghat and Hajipur), Kosi (near Baltara and Kursela), Burhi Gandak (at Khagaria), Punpun (at Sripalpur), and Bagmati rivers (at Benibad) are also flowing above their danger marks.

Significant Disruptions to Infrastructure and Transport

Rail Operations Affected: The East Central Railway has canceled and diverted a number of trains because the increase in the water level of a river close to the railroad bridge between Punpun and Parsa Bazar stations due to heavy rain created a danger to safety.

Rod and Flooded Police Stations: Numerous rural access roads and police posts in riverine regions are submerged, making it very hard to travel on roads.

IMD Weather Warnings and Projections

The IMD (India Meteorological Department) has released an upgraded warning owing to the continuing monsoon activities.

• Heavy Rainfall Records: Bihar has seen almost 69.1 mm of rainfall in September, which is between 55 % and 69 % above the normal rains for this season.

• Weather Report for next 48 Hours: Light to moderate rainfall with isolated heavy spells is expected to occur in the eastern and northern parts of Bihar.

• Advisory for the Residents: The authorities recommend that people do not venture into swollen rivers or attempt to use unlicensed/overloaded boats in floodwaters.

Relief, Rescue, and Emergency Response

The flood situation in Bihar in 2026 reveals an important weakness of the local communities living next to the rivers in the Ganga basin, underlining how the impact of heavy upstream rain coincides with the flood situations. The floods seen at such stations as Gandhi Ghat can be recorded at higher than average levels and only through cooperation of the water resources services, National Disaster Relief Force, and local government can lead to salvation.
