The school bell rang, then the hillside became a lifeboat for 900 children in Nepal's floods

Rajendra Dawadi had only moments to choose between waiting for certainty and moving hundreds of children out of danger. He rang the school bell, sent students and staff uphill, and watched floodwater swallow the school behind them.

He acted before anyone could confirm the worst

Dawadi was inside a classroom at Tribhuvan Trishuli Secondary School when a colleague ran in with a warning that floodwaters were surging through Nepal's Trishuli Valley, destroying homes, bridges and whole villages.

Another alert came through a phone call to a teacher. A parent also arrived to collect her child. The threat had not yet been confirmed, but Dawadi decided he could not wait. He stopped school immediately, rang the bell and ordered students and staff to leave the building and head for higher ground.

As the principal followed them toward a nearby hill, the water rose behind him. From there, he watched the school, where he had once studied and later taught, vanish under rushing water mixed with mud, boulders and debris.

Two staff members were unable to get out and remain missing.

At least 900 students were already on campus

The school had 1,643 students in total. At least 900 were there that morning when Dawadi gave the evacuation order. Some children were still on their way, which meant the response did not stop at clearing classrooms.

He contacted bus drivers and told them not to come to the school. One bus full of students had already reached the campus when he instructed the driver to turn around. The bus crossed a newly built bridge, and the older bridge next to it collapsed moments later, he said.

That series of decisions is believed to have saved at least 900 students from the flash floods that followed a glacial collapse in the Himalayas.

The wider disaster was catastrophic. More than 950 people were reported killed across Nepal and Tibet, while more than 4,400 were still missing.

The loss was bigger than one building

What happened at Dawadi's school was part of a broader education crisis spreading across northern Nepal. Thousands of children were left without classrooms, and there were warnings that the damage could disrupt schooling for months.

Save the Children said at least 69 schools in northern Nepal were destroyed, putting the education of nearly 19,000 students at risk.

For Dawadi, the destruction was also deeply personal. He said he had received his own education at that school and later gave education there as a teacher. The place that disappeared in the flood was not simply his workplace. It had shaped much of his life.

Parents thanked him, but he says the work is not finished

When Dawadi returned to the site of the school, parents hugged him and cried as they thanked him for saving their children. A 14-year-old student, Suvina Tamang, said the building was swept away shortly after the evacuation and said she wanted to thank him for saving her life.

Even with that response, Dawadi has not embraced the idea of being a hero. He has said that getting the children out was his responsibility.

His focus has already moved to what comes next. He said students will need psychological counselling, and that teaching must begin again, even if the school has to operate from a temporary location.

His message to the Nepalese government is straightforward: rebuild the schools and get children back into class.

Why floods can turn dangerous so quickly in mountain regions

In steep landscapes, heavy rain does not just sit on the ground. It races downhill, gathers in streams and river channels, and can rise fast enough to cut off roads, bridges and school routes. Water often carries mud, rocks, tree branches and debris, which makes it more powerful and harder to escape.

Another risk is that saturated soil can give way. That means flooding and landslides can happen together, especially after long or intense rain. Valleys, riverbanks and low crossings are usually the first places to become hazardous. Conditions can also change within minutes, so a route that looked passable earlier may not stay safe.

Why higher ground can act as a refuge

When water is spreading through low ground, moving to a stable, elevated area is often the safest immediate option. That is why hillsides, ridges and other high points are a basic part of flood planning in many rural communities. The goal is simple: get above the water and away from fast moving channels.

But higher ground is not automatically safe. Avoid slopes that show cracks, fresh mud movement, leaning trees or falling stones, because those can signal a landslide risk. Stay clear of river edges and narrow gullies, where water can surge unexpectedly. The best refuge point is high, easy to reach on foot, and far enough from both floodwater and unstable slopes.

Useful flood safety habits for families and schools

The most effective protection is knowing the plan before rain becomes dangerous. Children should know at least one safe route to higher ground, one meeting point, and one adult to follow if they are separated from family. Schools and households benefit from simple drills, clear signals such as a bell or whistle, and a rule that no one tries to wade through moving water.

Keep shoes, drinking water, a torch, basic medicines and a charged phone ready during wet weather. Listen for local warnings and watch the environment itself: sudden river colour changes, louder water, intense upstream rain and small slope slips can all be danger signs. If evacuation starts, go early. Most flood deaths happen when people wait too long or try to cross water that looks shallow.
