If you are in danger now, do not read this page. Call one of the four numbers below and tell them where you are.

These four reach an operator from any phone in Nepal, on any network, with no area code and no balance. They are the ones to use when you do not know who else to call. Say where you are before you say anything else, because a call that drops after you have given the location still gets someone moving.

The Budhi Gandaki flood of 11 October and the August flood are on different rivers that meet at Trishuli Dobhan, near Benighat. The one-way stretch of the Prithvi Highway at Galaundi is a road collapse from August's erosion, not water from either flood.Imperial College of Engineering, from 10:00 pm, 13 October 2026 reports. Schematic, not to scale.

NDRRMA’s technical report says a snow avalanche and a major landslide involving glacier ice and debris in the upper Ungdilung Khola triggered multiple surges down the Budhi Gandaki. The Flood Forecasting Section warned riverside communities at 6:40 am on 11 October. The Arughat gauge crossed its 5-metre danger level at 7:50 am; its last recorded reading that morning was 8.4 metres at 8:40 am. These are event-day readings, not a current river alert.

NDRRMA’s latest report, #3, lists 6 people still missing, 508 rescued, and 800 security personnel deployed as of 10:00 pm, 13 October 2026. It records 2 permanent, 5 suspension, 1 Bailey and 1 cantilever bridges damaged, along with 3 hydropower facilities, 1 school and 140 to 150 livestock swept away. The initial district estimate on 11 October put 35 to 40 houses at risk or lost; NDRRMA’s later report does not give an updated house total. Nepal Police’s 12 October update separately listed 5 missing and 48 rescued. The agencies’ counts differ and are not reconciled.

The report describes debris repeatedly blocking and releasing water downstream. On 11 October, NDRRMA, citing the Flood Forecasting Division rated the Trishuli at very high risk as far as Benighat and at high risk as far as Muglin. That warning was for the flood day. For travel now, check the dated road reports below and call Traffic Police on 103 before setting out.

If you are looking for someone

What to do · district policeWhich office takes the report, and the five things the officer will ask you for.

Step by step, including how to give a DNA sample: how to report a missing person after the Rasuwa flood.

Missing-person reports for this disaster are taken at district police offices, and they are collated centrally from there. Go to the district office where the person was last known to be, not the one where you live, because that is the office holding the recovery records for that stretch of river. If you cannot travel, call the province office in the list above and ask them to take it by phone.

Have these ready before you call, because the officer will ask for all of them:

  • Full name as written on the citizenship or passport, and age.
  • The last place they were known to be, and the last time anyone spoke to them.
  • What they were wearing, and any vehicle, plate number or bus they were travelling on.
  • A recent photograph, and any identifying mark.
  • Your own number, and a second number that will be answered if yours cannot be.

Give the same details to the Nepal Police control line on 100 as well. The two records are kept separately and a name in only one of them is a name that can be missed.

Relief for families, and what changed on 30 September

Relief · 30 September 2026The state's relief amounts, the route for families of the missing, and the move to search and recovery.

On 30 September 2026 the National Disaster Risk Reduction and Management Authority’s executive committee, chaired by Home Minister Sudhan Gurung, decided to move the government’s effort from rescue to search and recovery, because the chance of finding survivors has faded (Radio Nepal). On 5 October 2026 the National Council for Disaster Risk Reduction and Management, chaired by the Prime Minister, suspended the search and rescue phase for the time being and kept only urgent operations (OnlineKhabar).

For families of the missing, it approved a special administrative route so that relief does not wait for the 12-year legal declaration of death. The local government certifies the information, the District Administration Office certifies it again, and the authority then provides the relief. It is a route to relief and not a declaration of death.

The authority’s chief, Dharmaraj Upreti, said the state pays Rs 200,000 when one member of a family dies and Rs 100,000 for each further person, that this is immediate relief and not final compensation, that families whose houses were destroyed will get a separate package, and that a self-declaration that a relative is missing will be accepted (Kathmandu Post, 29 September). We have not found a published application form or portal, so please ask your ward office and the District Administration Office which papers they want.

3,685 DNA samples were being tested, 1,957 at the Nepal Police laboratory and 1,728 at the National Forensic Laboratory, and 112 bodies had been identified. How to give a sample is on the missing-person page.

Relief rules as of 30 September 2026

How to help, and the rule most people are breaking

One-door policy · money and goodsPrivate collections are illegal right now. Where the money goes instead, and the three collection points.

Relief for this disaster is being run under a one-door policy. Private organisations, groups and individuals may not independently collect money or materials for it, and unauthorised collections are illegal, including the ones being organised on social media right now. The reason is not bureaucratic: uncoordinated collections in past disasters put lorries of the wrong goods on the only open road while the right ones waited behind them.

So the college is not opening a fund and is not taking collections, and neither should you. Money goes to the Prime Minister's Disaster Relief Fund:

Goods, rather than money, go to one of three collection points. Call the focal person before you load anything, and ask what is actually needed that day. The answer changes, and the wrong pallet occupies a road.

The same list, on its own page with the date of the last check: Prithvi Highway and road status.

By the count of 30 September 2026, the flood destroyed 33 motorable bridges and 69 kilometres of road between Rasuwagadhi and Malekhu. When those bridges were washed out, helicopters were the only access for some settlements. The Betrawati Acrow bridge now restores one local link between Nuwakot and Rasuwa, while the latest Rasuwa-specific Police report we found lists the main road to Rasuwagadhi as blocked. Check 103 before you set out, not after. The latest source review was 27 October 2026; each road entry below carries its own report date:

  • Prithvi Highway

    Nepal Police reported Galaundi reopened at 6:10 am on 13 October; Nepal Live reported two-way traffic from 6:00 am

    The section subsided on 9 October after Trishuli erosion. The Dhading administration closed it overnight for repairs. Nepal Police reported it open at 6:10 am on 13 October; Nepal Live reported two-way traffic from 6:00 am. Nepal Police’s road notice of 27 October does not list it, which is not the same as a report that it is clear. Check Traffic Police on 103 before leaving; the repaired edge remains vulnerable.

    Nepalnews reported a landslide blocking the Kanti road at Takurche, Bagmati Rural Municipality-3, Lalitpur, on 2 October. On 10 October, small vehicles were diverted along it while the Prithvi was shut. No later road-status confirmation was found by 27 October, so this page does not label it open.

    Nepal Police’s 13 October road notice says a landslide at Khatri Pauwa, Dhunibesi Municipality-9, has restricted this highway to one-way traffic. The notice gives no schedule. Older reports about time windows farther south are not carried forward because those hours have passed. The 27 October notice does not list this highway, and we found no report that two-way traffic has resumed, so it stays marked one way. Check with Traffic Police on 103 before travelling.

  • Rasuwa highways (Trishuli to Rasuwagadhi)

    The latest Rasuwa-specific Police report we found, on 13 October, lists the main highways to Dhunche and Rasuwagadhi fully blocked; the Betrawati Acrow bridge was operating in the Nuwakot DAO report of 16 October

    Keep these two facts separate. Nepal Police’s latest Rasuwa-specific notice we found, dated 13 October, lists the main highways through Rasuwa as fully blocked. The Acrow bridge over Phalakhu Khola at Betrawati opened on 11 October, reconnecting Uttargaya in Rasuwa with Bidur in Nuwakot; the district office confirmed the bridge was operating in its 16 October update. This does not reopen the damaged road north to Dhunche, Syabrubesi or Rasuwagadhi. In late September the Department of Roads aimed to reopen Galchhi to Syabrubesi within Asoj and said Syabrubesi to Rasuwagadhi would take a few more months; we found no report by 27 October that either had opened. Confirm the route and vehicle access with Traffic Police on 103 before setting out.

  • Araniko Highway and the Tatopani crossing

    Tatopani opened to cargo vehicles only from 18 to 20 October; no regular reopening found

    Infrastructure Development Minister Sunil Lamsal told a parliamentary committee on Tuesday 6 October that the road on the Nepal side had already been reopened, and that the Chinese side did not yet appear ready to resume operations at Tatopani (PTI). On 30 September the Charikot road office had said the Nepali side ran one way during the monsoon. China then opened Tatopani for Kartik 1 to 3 (18 to 20 October) to cargo vehicles only, for Dashain goods, on the Ministry of Industry, Commerce and Supplies’ notice. We found no report of a regular reopening after that, so anything going north through Tatopani should be treated as stopped.

A silent gauge has sent nothing for more than a day, and its row shows its last reading with the date. The source still labels most silent gauges "below warning level", which cannot be true of a gauge that is measuring nothing, so this page does not repeat that label. A silent gauge upstream means the river above you is not being watched from that point, and a gauge downstream cannot warn you about water that has not reached it yet. In a glacier collapse or a landslide-dam burst the water can arrive before any gauge below it registers a rise, so the first warning may come from people upstream.

Every reporting gauge in Nepal, with rainfall, is on the river level tool; the Rasuwa rows alone are at river level in Rasuwa. If a settlement is cut off by water, the national disaster control room is 1112.

Source: Department of Hydrology and Meteorology gauges (hydrology.gov.np), read through the government's BIPAD portalabout ten minutes before the page loaded at most. The idea of following these gauges for this river came from Niraj Bhusal's Rasuwa flood bulletin.

What happened on the Trishuli

The flood · NDRRMA missing figure restated 16 October 2026A glacier collapse on the border, no monsoon behind it, and the count as it stands.

On the morning of 26 August 2026 (10 Bhadra 2083), shortly after 8:30 in the morning, an ice-and-rock avalanche from the north face of Langtang Lirung, on the Nepali side of the border, which fell about 1,200 metres into the Lhende Khola, the stream that marks the border, and ran on into the Bhote Koshi and then the Trishuli. There was no monsoon behind it and almost no warning: the wave covered its first stretch at roughly 193 kilometres an hour, the Trishuli rose 9 metres in 30 minutes, and it destroyed settlements along 72 kilometres of river. Nepal’s flood gauges in that reach are built for a river that rises over hours. This one arrived in minutes. The magnitude 5.2 tremor first reported as an earthquake was the landslide itself, according to the United States Geological Survey.

We could not reach NDRRMA’s own site to read the report itself. Nepal Police’s 14 October 2026 update lists 1,458 deaths and 4,720 people still under search. The agency totals differ and have not been reconciled. Nuwakot District Administration Office’s 16 October 2026, 6:00 pm local report lists 2,723 missing and 205 bodies not yet recovered in Nuwakot; that district register is not a national count. Rescued and treated totals are older, from 26 September 2026. Separate figures are reported across the border in Tibet. 11,332 people have been treated in all: 344 at health facilities and 10,988 by the security forces. The hydropower figure in the row above is the 31 August 2026 count, the last precise one the authority published; on 3 September it said only “around 900”.

What the count on eight days says, in words

Two line charts side by side, and they deliberately do not share a scale. The left panel is confirmed dead on a vertical scale of 0 to 1,400. The right panel is still missing on a scale of 0 to 5,200, nearly four times the left one. On a single axis the dead would flatten to nothing against 5,053 and the figure would misreport its own subject.

Confirmed dead, by date: 26 August, 95. 27 August, 359. 28 August, 389. 30 August, 734. 31 August, 903. 2 September, 1,204. 3 September, 1,259. 4 September, 1,294.

Still missing, by date: no count was published on 26 August. 27 August, 910. 28 August, 910. 30 August, 2,498. 31 August, 4,247. 2 September, 4,216. 3 September, 5,083. 4 September, 5,053.

The missing line falls twice, between 31 August and 2 September and again between 3 and 4 September. Neither is a correction: people moved out of the missing column and into the dead one, which is why the left panel climbs across the same days.

The dashed line marks 28 August, which is the figure this page printed for three days. It was right when it was checked and wrong three days later.

Nepal Police is not plotted. It published 1,290 on 4 September and 1,342 on 5 September, both above the authority this chart follows, on a basis that counts 532 partial remains among them. One series, one authority.

In NDRRMA’s report of 21 September 2026, the last to break the total down, 636 of the missing were foreign nationals, 164 were Nepalis travelling with those visitors and 83 were serving security personnel: 45 Nepali Army, 25 Nepal Police, 13 Armed Police Force. Those are that day’s numbers against a total that has since moved. The largest single group is the 933 people who were at work on the hydropower projects, and they have their own post below.

The flood · 8 districtsThe dead and the missing are not in the same places, and the difference is the reason this reaches Chitwan.

The deaths and the missing are not in the same places, and if you are reading this from Chitwan or Nawalparasi that difference is the reason this is your disaster too. The water started at the Nepal–China border and it was still killing people 240 kilometres later, across the Indian border. Upstream, in Rasuwa and Nuwakot, it mostly did not leave bodies to recover.

What deaths by district says, in words

Deaths by district from Nepal Police’s update of 14 October 2026. The rows run in river order rather than by size, so reading top to bottom is travelling downstream from the Nepal-China border towards the Indian border.

Rasuwa, 237. Nuwakot, 205. Dhading, 73. Gorkha, 80. Tanahun, 38. Chitwan, 369, the longest bar. Nawalparasi East, 232. Nawalparasi West, 222.

A final bar, drawn in grey and set apart because it is not a place, carries 2 people who died in hospital in Kathmandu during treatment.

The eight district rows add to 1,456. Together with the two deaths during treatment in Kathmandu, the nine displayed rows add to 1,458, Nepal Police’s total on 14 October. NDRRMA separately reported 1,455 deaths through 3 October.

The chart reports deaths by district only. It does not split missing people by district. Nuwakot District Administration Office’s 16 October report separately lists 2,723 people missing and 205 bodies not yet recovered in Nuwakot.

Where it stopped. Everything grey in this frame arrived on one morning, and the line it stopped at is the only reason the houses above it are standing.Kamal Prasai and Dinesh Gautam, Onlinekhabar.

The line that debris stopped at is the only thing separating the houses above it from the ones that are not there any more, and it was decided by the shape of the ground rather than by anything anybody did.

Rasuwa and Nuwakot are the districts the flood hit hardest. The most deaths in Nepal Police’s 14 October 2026 tableare in Chitwan and Rasuwa. Its eight district rows and two deaths during treatment in Kathmandu add to 1,458. The chart above uses that Police table. NDRRMA’s separate Bhotekoshi report lists 1,457 deaths through 16 October 2026. Nuwakot’s district report of 16 October 2026, 6:00 pm lists 2,723 people missing and 205 bodies not yet recovered locally. The Nuwakot register is not reconciled with the national missing counts. The government has declared 3 days of national mourning, has declared the affected local levels a disaster zone for 3 months, and has ordered treatment free at government hospitals for anyone injured in this flood.

We asked whether this loss was preventable, and put the question to two AI research agents arguing opposite sides. Their briefs, rebuttals and the points they agreed on are in our report on the 2026 Bhotekoshi flood, with sources, for anyone studying or teaching it.

How it actually happened

Engineering · the mechanismA bedrock failure, a debris dam, and the wall nobody had designed and nobody was watching.

In short: A bedrock and glacier mass of 100 to 200 million cubic metres failed on the north face of Langtang Lirung, on the Nepali side of the border and about 20 km north-east of the Rasuwagadhi crossing, at 08:37 on 26 August and became a debris flow down the Bhote Koshi and Trishuli. It was not a monsoon flood, a glacial lake outburst, or an earthquake. Read the full analysis in our Rasuwa flood report.

This was not a monsoon flood and it was not an earthquake, and both of those are still being repeated. What happened was a bedrock failure high on the ridge, about 20 kilometres above the border, which took the glacier sitting on top of it down as well. A face roughly 600 metres across fell 1,200 metres into the Lhende Khola. The United States Geological Survey first read the shock as a magnitude 4.4 earthquake and later corrected it: the magnitude 5.2 signal was made by the collapse, not the other way round.

What how the flood happened says, in words

Six steps, in the order they happened. One: at about 08:40, at 5,200 metres, bedrock fails on the ridge north of Langtang Lirung on the Nepal to China border, and the glacier sitting on that rock goes down with it. There was no earthquake. The collapse made its own seismic signal, magnitude 5.2.

Two: a face about 600 metres wide, between 100 and 200 million cubic metres of rock and ice, falls about 1,200 metres into the Lhende Khola. Three: the debris blocks the river, and water ponds behind a wall of loose rock and ice that no engineer designed and nobody was watching. That is the part that buys minutes, and the minutes were not used.

Four: the debris dam gives way and everything behind it leaves in one release rather than over a day. Five: friction melts ice into the flow and the flow tears sediment off the bed and the banks, so it leaves as water and arrives as moving ground. At Timure it was described as a wall of water about 100 metres high.

Six: about 100 kilometres downstream the Trishuli rises 9 metres in 30 minutes at Galchhi and 7 metres at Malekhu, a long way from any glacier, on a day with no rain. Most of the people who died were below this point, not above it.

Sources: ICIMOD, the United States Geological Survey, Planet Labs imagery and Nepal’s Department of Hydrology and Meteorology, as reported by the Kathmandu Post on 28 August 2026. Times are approximate and the collapse volume is a published range.

The volume is the part that is hard to hold in your head. Between 100 and 200 million cubic metres of rock and ice came off the mountain at once. What made it lethal, though, was not the volume but the sequence: the debris dammed the river, water ponded behind a wall nobody had designed and nobody was watching, and then that wall failed. A river that would normally carry that water over a day carried it in minutes.

A steep narrow gorge with near-vertical rock walls scoured pale by the passing flood
A confined gorge is why it moved so fast. The same volume through a narrower section has to go quicker and higher, and the pale band is how high.Kamal Prasai and Dinesh Gautam, Onlinekhabar.

It also arrived bigger than it left. Friction melted ice into the flow, and the flow tore sediment off the bed and the banks as it went, so what started as water reached the settlements as moving ground. At Timure it was described as a wall of water about 100 metres high. That is why the damage does not look like flooding.

The buildings in that frame did not fall down. The ground came up around them, which is why the recovery is being done with excavators rather than by searching rubble, and why the missing outnumber the dead by about 3.6 to one.

Why nobody was warned

Engineering · the warning chainThe collapse was detected within seconds. Nothing turned that reading into a warning.

In short: The collapse registered on seismometers within seconds, but the warning travelled by telephone and took about 51 minutes, longer than the 35 minutes the flood took to reach Nepal. Read the full analysis in our Rasuwa flood report.

The collapse was detected. A seismometer at Jilong, 12 kilometres away, recorded it within seconds, and so did the station at Zhangmu. Nothing turned that into a warning. Nepal’s Department of Hydrology and Meteorology found out about the flood roughly 16 minutes after it had already crossed the border, by telephone, relayed from the Rasuwa district office through the national disaster authority. The SMS alerts went out after that, by which time upper Rasuwa was gone.

What the warning timeline says, in words

Two tracks across one hour on 26 August 2026, from 08:40 to 09:40. Times are approximate, because the sources give them to the nearest few minutes.

The wave: at 08:40 the rock and ice collapse happens, on the north face of Langtang Lirung on the Nepali side of the border. At about 09:15 it crosses into Nepal at Rasuwagadhi, then Timure, and both are destroyed within minutes.

The warning: at 08:40, within seconds, seismometers at Jilong 12 kilometres away and at Zhangmu record it. Then 51 minutes of nothing reaching anyone. At about 09:31 the Department of Hydrology and Meteorology finds out, relayed by telephone from the district office and then NDRRMA. The SMS alerts follow that, after upper Rasuwa is already gone.

The point of the figure: nothing here needed a better sensor. It needed a wire between a sensor that already fired and a siren that never rang.

The obvious question is why the river gauges did not catch it, and the answer is that they are the wrong instrument for this. A gauge measures a flood that has already arrived. On a monsoon flood that is enough, because the level climbs for hours and the crossing of a threshold leaves time to act. On this, the level crossed every threshold and the peak arrived in the same few minutes, and several of the gauges were destroyed immediately afterwards.

Two hydrographs on one axis: a monsoon flood rising over hours against a glacial surge rising in minutes
Why a river gauge could not help. The same alarm threshold gives an hour of warning on the blue curve and none on the red one.Curves are schematic. The 9 metres in 30 minutes at Galchhi is measured.Scroll the diagram sideways to read it, or open the two hydrographs at full size.Imperial College of Engineering.
What the two hydrographs says, in words

Two river-level curves on one axis, hours across the bottom from 0 to 8 and metres up the side from 0 to 9, with a horizontal alarm threshold drawn across both.

The blue curve is a monsoon flood. It climbs gradually across several hours, crosses the alarm threshold, and only peaks well after it. The gap between the crossing and the peak is about an hour of warning, and that gap is what makes a gauge useful.

The red curve is 26 August. It sits flat, then goes almost vertical: 9 metres in 30 minutes. It crosses the alarm threshold and reaches its peak inside the same few minutes, so the threshold buys nothing, and the gauge is usually destroyed next.

The curves are schematic. What is measured is the 9 metre rise in 30 minutes at Galchhi and 7 metres at Malekhu, and that Nepal’s Department of Hydrology and Meteorology recorded no heavy rainfall in Rasuwa on either day.

A gauge measures the flood arriving. To warn anyone upstream of it, you have to detect the cause, not the consequence.

Underneath both of those is a problem Nepali equipment alone does not fix. The collapse was on the Nepali side of the border, but at the head of a valley the two countries share. Every instrument Nepal owns on this river sits below the thing that needed detecting, and the one instrument that recorded it, a seismometer at Jilong in China, belongs to a state with no agreement in place to turn its readings into an alarm here. This is the third flood in three years to come down this same transboundary watershed.

What the blind spot at the border says, in words

A schematic strip down the river, in correct order, with the border at Rasuwagadhi marked across it. At the head of the strip is the border valley, where the Lhende Khola marks the border; below the Rasuwagadhi crossing it is Nepal all the way down. The watercourse is the Lhende Khola, then the Bhote Koshi, then the Trishuli.

At the head of the valley: the collapse, on the Nepali side, at 5,200 metres, about 20 kilometres up, and the Jilong seismometer in China, 12 kilometres away, which recorded it.

On the Nepali side, in order down the river: Timure, Syabrubesi, Dhunche, Betrawati, Bidur, Galchhi, Malekhu, Chitwan. Nepal’s river gauges begin at Rasuwagadhi, on the border, so every one of them is downstream of the collapse. Every settlement that lost people is in this reach, and none of it could see upstream.

Only the 12 kilometre and 20 kilometre figures are stated, because those are the two that are published. The distances along the strip are schematic and only their order is meant.

Nepal’s instruments are all below the hazard. The one instrument that recorded it belongs to another state, and no agreement turns its reading into a siren here. This is the third flood in three years to come out of this same transboundary watershed.

Dozens of hydropower workers in hard hats sitting and standing outside a tunnel mouth after being rescued

The people inside the power stations

The flood · 933 missing from 11 projectsThe wave went through working power stations in the middle of a Wednesday shift. This is our own profession.

In short: Run-of-river hydropower puts intakes, powerhouses, camps and shifts on the valley floor, so the flood went through working power stations. Hundreds of hydropower workers are among the missing. Read the full analysis in our Rasuwa flood report.

The Trishuli is a hydropower river, so the wave went through working power stations in the middle of a Wednesday shift. 933 people who were at work on those projects are missing, across 11 projects, and 361 have been rescued or walked out on their own. They were civil, electrical and electronics engineers, technicians and construction crews. This college’s own profession, and most of them will have trained in colleges like this one. We are an engineering college and we are not going to write about this flood without saying so.

That figure was 133 on this page from 28 to 31 August, when only four projects had reported. That count is about one in 6 of everyone now listed as missing in the whole disaster. The two bodies counting it do not quite agree, which is normal this early and is better said than smoothed over: the National Disaster Risk Reduction and Management Authority says 933 and the Independent Power Producers’ Association says 934.

Most of them are underground. The Nepali Army has put 19 tunnels in priority order, and this is what a rescue at one of them is actually trying to do. On 30 September 2026 the government moved its effort from rescue to search and recovery, because the chance of finding survivors has faded, and searching was still going on at two tunnel sites.

What the tunnel long-section says, in words

A schematic long-section of a run-of-river scheme on the Trishuli, cut through the mountain the tunnel is bored through. Not to scale, and not a survey of any one project.

Five numbered features. One, the portal: the way in and out, and it is under the debris. Two, the headrace tunnel, about 7 metres across, intact and full of water, running off towards the intake upstream. Three, the rescue bore, drilled from the surface, with air pumped in and food and ropes lowered through it. Four, the surge shaft, one of the few other ways in. Five, the powerhouse and yard, under 10 to 18 metres of debris.

The sentence the drawing exists for: the tunnels did not collapse, everything around them did, so the rescue is not digging people out, it is digging its way in.

At Trishuli 3A the Nepali Army found the tunnel crown on 30 August, drilled through it, and found water standing high inside a bore about seven metres across. Ropes went down, rescuers called, and nothing answered. At Upper Trishuli-1, 350 people were brought out and more than 100 are still believed to be inside.

  • Upper Trishuli-1

    350 people have been brought out of the tunnel at this 216 MW project in Rasuwa. More than 100 are still believed to be inside it.

  • Trishuli 3A

    The Army found the tunnel crown on 30 August and drilled through it. Water is standing high inside a bore about seven metres across. Ropes went down, rescuers called, and nothing answered. The Army puts at least 35 people inside; Nepal Police puts it near 200.

  • Langtang Khola

    Around 60 workers were inside a tunnel. The powerhouse was swept away days before the project was due to start generating.

  • Rasuwagadhi and Chilime

    Staff are unaccounted for after the plants and the customs yard beside them were destroyed. Over 300 vehicles went with them.

431 megawatts left the national grid with them, and another 470 megawatts of projects still being built were damaged, so expect power cuts for a long time. If you are a family member of someone who was on one of these sites, the project operators are reporting to the district authorities, and the missing-person route above is the same one everybody else is using. Use it as well, not instead.

There is a design question inside that number, and it is a question rather than an accusation. The Trishuli carries 10 projects that were damaged or destroyed in one morning. A run-of-river scheme puts its intake, its powerhouse, its yard and its shift on the valley floor, because that is where the water is. The valley floor is also the one place a debris flow is guaranteed to go.

The totals along the bottom: 431 MW off the national grid, another 470 MW under construction and damaged, and 933 people from this one industry missing.

The design point, and it is a question rather than an accusation: a run-of-river cascade puts the intake, the powerhouse, the yard and the shift on the valley floor, which is the one place a debris flow is certain to go. Siting and a tunnel exit that does not lead back to the river are design choices.

What would actually prevent this

Engineering · preventionNothing on this list stops a mountain coming down. All of it buys minutes for the people below.

In short: Nothing stops a mountain coming down, but an automatic trigger on a silent border gauge, a live data link with China, clear alerts and a second road would buy minutes and keep the capital connected. Read the full analysis in our Rasuwa flood report.

The honest starting point is that nothing on this list would have stopped the mountain coming down. The question is only ever how much of the 35 minutes between the collapse and the first Nepali village you can hand to the people living in it, and how much more you can hand to everyone further down.

Three-column comparison of the 51-minute human warning chain against an automated seismic trigger and its 35-minute margin
What would actually have bought time, and the two reasons it is harder than it looks. The margin was real: 35 minutes before the wave reached the first Nepali village.Scroll the diagram sideways to read it, or open what would have bought time at full size.Imperial College of Engineering.
What what would have bought time says, in words

Three columns. The first is what happened: a seismometer records the collapse, the reading stays where it is, the wave destroys Timure, someone telephones the district office, the district office telephones NDRRMA, NDRRMA tells the hydrology department, and an SMS goes out. Total, 51 minutes, all of it human.

The second is what the same sensors could do: a seismometer records the collapse, the signature is matched against a mass-movement rule rather than an earthquake rule, a threshold fires with no human in it, sirens sound in the valley below, and a cell broadcast reaches every handset in the cell rather than an opt-in SMS list. Total, seconds, all of it machine.

The third is the margin it would use. The collapse was at about 08:40 and the surge crossed into Nepal at about 09:15, so there were 35 minutes before it reached the first Nepali village. Every settlement below Timure had more than that, increasing with distance. Chitwan had hours.

Two honest caveats, because this is not a solved problem. The hard part is not the electronics; it is an agreement that lets a reading taken in one country ring a siren in another, and this is the third flood in three years out of that same watershed. The second hard part is maintenance: a siren nobody services is a siren that does not sound, which is exactly what happened to the system Nepal already built at Tsho Rolpa.

The first fix is not a better sensor. It is an automatic path from a sensor that already fired to a siren that never rang, and a cross-border agreement that lets a reading taken on one side of a line ring a bell on the other. The electronics for that are cheap and forty years old. The agreement is the hard part, and it is the part that has now failed three times in three years on this one river.

The second is the standing inventory. Nepal, Tibet and India between them hold 3,624 mapped glacial lakes. 47 of those are rated potentially dangerous, and 21 of those are inside Nepal. Two have had mitigation work done on them, on the most recent count we could source, which is a 2011 ICIMOD study. If a newer figure exists it should replace this one.

What the glacial lake inventory says, in words

A funnel in four steps, from the ICIMOD and UNDP inventory of the Koshi, Gandaki and Karnali basins.

Step one: 3,624 glacial lakes mapped, of 0.003 square kilometres and larger. Nepal 2,070, Tibet 1,509, India 45.

Step two: 47 of those are assessed as potentially dangerous. China 25, Nepal 21, India 1. Forty-two of the 47 are in the Koshi basin.

Step three: 21 of the 47 are inside Nepal. Step four: 2 of those 21 have had proper mitigation work. That 2-of-21 is from a 2011 ICIMOD study and is the most recent this page could source; if a newer count exists it should replace it.

Since 1977 Nepal has recorded 26 glacial lake outburst floods, and 14 of them started inside the country. The 26 August flood was not an outburst at all: ICIMOD calls it an ice and rock avalanche that began on the Nepali side, with no lake behind it.

There was no lake behind this flood, which is worth saying plainly: ICIMOD calls it an ice and rock avalanche that began on the Nepali side, so a lake programme would not have reached it, and the 21 lakes inside Nepal are the ones Nepal can still act on. Since 1977 the country has recorded 26 outburst floods, and 14 of them started at home. Those are the ones a lake programme reaches.

The last one is the uncomfortable one, and it is the reason this section exists on a college website rather than a ministry one. Nepal has already built exactly the system everyone is now calling for.

Timeline of the Tsho Rolpa lake lowering and warning system, built by 2002 and out of service from the same year
Nepal has built one of these before. The hydrology was right and the structure got built, and it still protected nobody.Scroll the diagram sideways to read it, or open the Tsho Rolpa lesson at full size.Imperial College of Engineering, from the published project record.
What the Tsho Rolpa lesson says, in words

The problem: Tsho Rolpa grew from 0.23 to 1.65 square kilometres between 1957 and 1997, holding 90 to 100 million cubic metres behind nothing but a moraine, with the Khimti hydropower plant being built underneath it.

A timeline in three marks. 1998: work starts. 2002: complete, at USD 3.2 million, with the lake lowered 3 metres and sirens and air horns in 19 villages fed by 17 warning stations on VHF radio. 2002 onwards: it stops working, through management and then the insurgency, and was judged later as too complex to keep alive.

Two findings sit under the timeline. The engineering was not finished: full mitigation needed the lake down by 20 metres and it came down 3, so the other 17 metres were never funded and the lake is still there. And the warning was funded as a building: a siren network is an operating commitment with a budget every year and someone whose job it is, and it was paid for once, as construction, and then it was nobody’s.

The hydrology was right and the structure got built. It still protected nobody, because the maintenance was never anyone’s line item. That is a design failure, and it is the one most likely to be repeated after this flood.

Tsho Rolpa was lowered 3 metres of the 20 its engineers said full mitigation needed, for US$3.2 million, with sirens and air horns in 19 villages fed by 17 warning stations. It was finished in 2002. It stopped working in 2002. The hydrology was right and the structure got built, and it still protected nobody, because a warning network is an operating commitment with a budget every year and a named person responsible, and it was paid for once as construction and then belonged to nobody.

That is the failure most likely to be repeated after this flood, while the money is available and the attention is on. If a student reading this ends up working on the reconstruction, it is the thing worth arguing about in the meeting.

There were deadlines we could not move, and you should know how they fell. The second IOE merit list published on 30 August, 10:00 am, and admission from it ran to 2 September, 3:00 pm. The third list published 6 September, 10:00 am, and admission from it closed 8 September, 3:00 pm. Those hours were set centrally by the Institute of Engineering, not by us, and that was the end of the central schedule. If the roads cost you one of those windows, you are not finished: fourth and later lists run on each campus's own published timetable, and seats that fall vacant can be filled as late as 3 December. Ring us and we will tell you what your rank still reaches. The Prithvi Highway is the road most applicants from west of the Valley travel on. It reopened at Krishnabhir on 17 September, was blocked again by landslides on 26 September, reopened to all vehicles on 30 September, and was reported two-way on 1 October. On the evening of 9 October it subsided at Galaundi near Gajuri and shut again, and the Department of Roads ran it one way from the night of 10 October. The roads section above has where every route into the Valley stood on 27 October 2026.

You do not have to be standing at our counter to take the seat. Our online admission desk completes the whole thing from a phone. You sign in with the IOE roll number you already have, and it works on a slow connection. Bring your original documents to campus whenever the roads let you. If you would rather have a person do it with you, call the number above and we will walk through it on the phone.

If you are already studying here rather than applying, IOE has revised your Bhadra semester routine twice, on 31 August and again on 2 September. The regular BE and BAR papers are dated from 13 September, one year at a time over four days. How far your own papers moved depends on your year, and it is not the same number for anybody. We read all three routines against each other and published what moved, beside the road status above, at getting to the examination hall on the revised dates.

If the flood put you in hospital, in mourning, or out of your home, and you missed a paper because of it, Tribhuvan University's Registrar wrote on 3 September that you get a separate sitting on par with the regular exam, on certified documents. Applications went through your own campus or college by 15 September, and every campus had to have them at IOE's Examination Control Division by 17 September. Both deadlines have passed. On 23 September IOE published the timetable, notice 15539: five papers, 2 to 9 October, every one at 1:00 pm, at Pulchowk Campus. The earlier letters named the week of 24 to 30 September, and the sitting is not in that week. The five papers and what changed are on our notice board. If you filed and a paper is not among the five, call the number above and we will find out where it stands.
