The Gandak flood situation is not moving in one direction everywhere. The latest official Bihar FMIS/CWC observation used for this article was recorded at 11:00 IST on August 27, 2026. It showed some monitored Gandak stations falling, while two important stations were still rising above their official warning or danger thresholds.
Which Gandak stations were still rising?
At 11:00, Dumariaghat in Gopalganj was at 62.55 metres, above its 62.22-metre danger level, and the official trend was rising.
Thakraha in West Champaran was at 76.95 metres, above its 76.68-metre warning level, and was also rising.
| Station | 11:00 level | Official threshold | Status | Trend |
|---|---|---|---|---|
| Dumariaghat | 62.55 m | Danger: 62.22 m | Above danger level | Rising |
| Thakraha | 76.95 m | Warning: 76.68 m | Above warning level | Rising |
| Lalganj | 50.60 m | Danger: 50.50 m | Above danger level | Falling |
| Bagaha | 89.15 m | Warning: 88.30 m | Above warning level | Falling |
| Hajipur | 49.42 m | Warning: 49.32 m | Above warning level | Steady |
Why reports that the Gandak is ‘receding’ can still be correct
Earlier on August 27, Bihar Water Resources Department figures reported through PTI showed that discharge at the Valmikinagar barrage had fallen substantially from its overnight level. That supports the broader assessment that the upstream surge was easing.
But falling barrage discharge is not the same measurement as the water level at every downstream gauge. Water already moving through the river system can leave different stations at different stages of the flood wave. That is why one location can be falling while another remains above its threshold and is still rising.
What ‘above warning level’ and ‘above danger level’ mean here
The thresholds are station-specific reference levels used by official flood-monitoring systems. A station being above its warning or danger level is an important flood-risk signal, but TPS is not treating the gauge reading alone as proof that every nearby village, road or property is flooded.
Likewise, this article does not assume that a locality is safe merely because a station has started falling. A falling reading can remain above its warning or danger threshold for some time.
What is not confirmed from the 11:00 river readings
The reviewed evidence does not establish a blanket evacuation order, statewide road closure or school closure for every Gandak-linked district. It also does not establish the exact time at which the downstream river will fully recede.
Local impact should therefore be checked separately against the latest district administration, disaster-management and access instructions.
What readers should check next
The most useful next signal is a newer official FMIS/CWC observation. For Dumariaghat and Thakraha in particular, the key question is whether the next readings show the rising trend continuing, becoming steady or reversing.
This article uses the 11:00 IST August 27 observation as a timestamped official snapshot. ThePulseSignal will treat later river readings as a freshness update rather than silently presenting these measurements as permanently current.
