Muzaffarpur flood guide: Why Muzaffarpur Floods
Three facts explain the risk.
- Flat land: The district lies on a flat plain, so water spreads wide and drains slowly.
- Many rivers: The Gandak, Burhi Gandak, Bagmati and Lakhandei all drain the district.
- Rain upstream: Heavy rain in Nepal and the hills feeds rivers that flow into Bihar.
So a storm far away can cause high water in Muzaffarpur a day or two later. That is why officials watch river levels in Nepal and north Bihar together.

Muzaffarpur flood guide: What Is a Danger Mark?
Each river has gauge stations. In addition, Officials measure the water level at each station. Additionally, For each one, they fix a “warning level” and a “danger level” (or danger mark). When the river crosses the danger mark, flooding becomes likely in nearby low areas.
Here are three danger marks that news reports quote.
| River and station | Danger mark |
|---|---|
| Bagmati at Kataujha | 55.00 metres |
| Burhi Gandak at Sikandarpur | 52.53 metres |
| Gandak at Rewaghat | 54.41 metres |
A river above its danger mark means low areas nearby face a real risk of flooding.
How to read a flood alert
How to Read a Flood Report
A news report may say the Bagmati flows “1.5 metres above the danger mark”. That means the water level is 1.5 metres higher than the danger mark at that station. Besides, the higher the gap, the bigger the risk. A report may also say a river is “rising” or “falling”. Watch that trend, since a falling river can still cause damage in low areas.

Flood alerts return almost every monsoon. Moreover, In July 2024, news reports said houses were inundated in Muzaffarpur as the Bagmati swelled.
