Pakistan installs 286 glacial flood warning systems in the north
The $37 million GLOF-II project covers 24 valleys in Gilgit-Baltistan and Khyber Pakhtunkhwa, amid questions over systems that do not work.
Pakistan is installing 286 early warning systems for glacial lake floods in 24 northern valleys, under a 37 million dollar project called GLOF-II, Dunya News reported on 17 August 2026, citing the state news agency. Two weeks later, the Pamir Times warned that installing equipment is not enough if systems are not maintained and warnings do not reach villages.
- $37mtotal cost of the GLOF-II project
- 18 and 6valleys in Gilgit-Baltistan and Khyber Pakhtunkhwa
- 155people killed in Pakistan's 2026 monsoon by mid-August
- 21potentially dangerous glacial lakes inside Nepal
- 6,000households at risk below Nepal's Tsho Rolpa lake
What happened
According to Dunya News, which cited a government document reported by the Associated Press of Pakistan (APP), the systems are going into 24 vulnerable valleys. Eighteen are in Gilgit-Baltistan, a high mountain region in the far north, and six are in the province of Khyber Pakhtunkhwa. The document puts the total cost of the project at 37 million US dollars.
GLOF-II is the second phase of a programme against glacial lake outburst floods. The Pamir Times describes it as a project of the Government of Pakistan with the United Nations Development Programme (UNDP), supported by the Green Climate Fund. It has paid for early warning systems, community disaster risk centres, evacuation shelters and protective works. Dunya News reports that the first phase, GLOF-I, ran from 2011 to 2016 with money from the UN Adaptation Fund.
The report came during a deadly monsoon. Dunya News, citing Pakistan's National Disaster Management Authority, says at least 155 people had been killed and more than 460 injured in rains and floods since June 2026. It also recalls the 2022 floods, caused by record monsoon rain and glacier melt, which killed more than 1,700 people, affected over 33 million and caused about 30 billion dollars in losses.
The engineering behind it
A glacial lake forms when meltwater from a retreating glacier collects behind a natural dam. The dam is usually ice or a moraine, a loose pile of rock and sediment left by the glacier. In general, the dam can fail when an avalanche or rockfall hits the lake and sends a wave over it, when buried ice inside the moraine melts, or when water builds up faster than the lake can hold.
An early warning system has several parts, and each one has to work. Sensors such as water level gauges, rain gauges and weather stations measure what is happening near the lake. A data link, often by radio or mobile network, sends the readings to a control centre. Software or a trained person decides whether the readings mean danger. Finally, sirens, phone messages or local volunteers must tell people downstream to move to safe ground.
The weak points are usually not the sensors themselves. Equipment at high altitude needs reliable power, often from solar panels and batteries, through long cold winters. Data links fail when mobile networks are weak. Sensors drift and break and must be checked and repaired. Someone must be responsible for watching the data at all hours. The time between a lake bursting and the flood reaching a village can be very short, so every delay matters.
Why the numbers are not the whole story
The Pamir Times analysis of 29 August argues that the real test is whether the whole system works when danger comes. It reports that in April 2026, Prime Minister Shehbaz Sharif ordered a high-level inquiry into a non-working glacial flood warning system in Gilgit-Baltistan, and directed that the systems and their digital monitoring be made fully functional.
The paper raises two separate concerns. The first is whether every vulnerable valley is covered at all. The second is whether the systems already installed are working, maintained and monitored. It says a warning only saves lives when the technology works, responsibilities are clear, communication channels stay open, and people know what to do. It also points out that in remote valleys, local communities are often the first responders when roads, bridges and phone networks are cut.
The Pamir Times also argues that most visible government work still happens after a disaster, in rescue, relief and repair. It calls for a shift toward preparation: continuous monitoring of glaciers and unstable slopes, regular testing and maintenance of warning systems, clearly marked evacuation routes and regular community drills. In its view, success should be measured by whether a warning reaches the last settlement in time, not by how many sensors were installed.
What it means in Nepal
The Pamir Times wrote its analysis in response to floods along the Nepal-Tibet border. Nepalnews reported that a flood on 26 August 2026 tore down the Bhote Koshi and Trishuli rivers, and that 903 people had died by 31 August. Early assessments pointed to a large glacier collapse in the Lhende Khola valley, upstream in Tibet, rather than a classic lake burst.
Nepal already lists its own dangerous lakes. Nepalnews reports that a joint assessment by ICIMOD, the International Centre for Integrated Mountain Development, and the government classified 47 glacial lakes as potentially dangerous. Of these, 21 are in Nepal and 25 are in Tibet, at the head of rivers that flow into Nepal.
Nepal has met the same maintenance problem that Pakistan's prime minister complained about. Dialogue Earth reported in 2024 that the early warning systems at Tsho Rolpa, one of Nepal's most dangerous lakes, were installed more than 20 years earlier and had been damaged long ago. The local mobile network was also poor. About 6,000 households downstream were at risk. An ICIMOD expert suggested cameras linked to a telemetry system to watch the lake in real time.
What to study if this interests you
Engineering Hydrology, ENCE 306, in the fifth semester of BCE, teaches how floods are estimated, and Hydraulics, ENCE 251, in the fourth semester, explains how water flows in channels and over obstacles. For BEI students, Instrumentation, ENEX 252, in the fourth semester, covers sensors and measurement, and Embedded Systems, ENEX 302, in the fifth semester, covers the small computers that log data and send it from remote mountain sites to a control centre.
