# Nepal flash floods push Bihar on high alert; relief teams on standby

Nepal’s flash floods prompted Bihar to prepare for possible downstream flooding, with gates opened as a precaution and disaster teams deployed. Officials warn of rising Gandak levels and coordinated rescue efforts continuing after an 9 am surge in Bhote Koshi.

## Key takeaways

- A 9 am surge in Bhote Koshi prompted precautionary flood management in Bihar, including gate openings at Valmikinagar.
- Discharge at Gandak Barrage stood at about 86,000 cusecs by noon with rising trend reported by officials.
- Nepal reported damage to hydropower facilities and power disruptions; Nepal Army deployed helicopters for relief.
- Disaster management teams in India were placed on standby and a central flood control cell was activated to coordinate reporting and response.

## What Happened

The incident involved flash floods triggered by a glacial lake outburst in Nepal’s northern region near the Tibet border. Officials reported a sudden surge in the Bhote Koshi (Bhote-Koshi) around 9 am, with an approximately three-metre rise in water levels. Downstream, the Gandak river system saw rising discharge after the upstream surge, with the Gandak Barrage at Valmikinagar receiving about 86,000 cusecs around noon and continuing to rise. In Nepal, the Devghat gauge showed river levels around 4.77 metres, with a danger level marked at 9 metres and a warning level at 7.30 metres. Nepal’s authorities reported damage to electricity infrastructure and several hydropower facilities, and closures of major highways as the floods impacted transport and power transmission.

Across the border in Bihar, India, authorities opened all 36 gates at the Valmikinagar barrage as a precaution. A technical team led by a superintending engineer was dispatched to monitor the barrage. Disaster management teams were put on standby, and an emergency meeting was held to maintain high alert and coordinate potential evacuations. The state activated the Central Flood Control Cell around the clock and established hotlines for flood-related reporting. The situation prompted additional coordination with districts along the Gandak’s course, as officials warned of possible evacuations if water levels rose further.

## Why It Matters

The event underscores cross-border hydrological links and the way upstream floods can affect downstream regions. Bihar’s preparations, including gate operations and deployment of disaster response forces, reflect a policy response aimed at mitigating flood risk and enabling rapid evacuations if needed. The broader regional impact includes damage to power infrastructure in Nepal, which can have knock-on effects for electricity supply and transport networks in bordering districts.

## Background

Flash floods in northern Nepal often interact with the Gandak river system, which runs through northern India. The timing noted by officials places the upstream discharge several hours ahead of potential downstream impacts, creating a window for precautionary actions by adjoining states. The floods followed a period when monsoon activity commonly drives elevated river levels in both Nepal and northern India.

## Key Facts

- Bhote Koshi surge around 9 am due to an outburst in Nepal’s northern region near Tibet.
- Gandak Barrage at Valmikinagar reported 86,000 cusecs discharge at noon, with rising trend anticipated.
- Devghat gauge in Nepal recorded about 4.77 metres; danger level is 9 metres, warning level 7.30 metres.
- Bihar opened all 36 gates at Valmikinagar as a precaution; a technical team was sent to monitor the barrage.
- Disaster response forces (NDRF/SDRF) deployed in potentially affected areas; Central Flood Control Cell activated in Patna.
- Officials warned of potential evacuations and urged use of helplines for flood-related emergencies.
- Nepal reported damage to hydropower facilities and disruption to electricity supply; Nepal Army and other agencies conducted search and relief operations.
- evacuations and high alert were coordinated through a high-level meeting with district authorities and senior officials.

## What Happens Next

Authorities indicated ongoing monitoring of river levels and continued readiness to deploy evacuation and relief resources if Gandak discharge rises further. Multi-agency coordination, including emergency meetings and public alerts, will continue as officials assess downstream impacts and infrastructure resilience.
