In a startling admission, Nepalese officials disclosed that an early flood warning system, designed to safeguard communities around Mount Everest, has fallen into disrepair over the years. The system, supported by the UN, has not been inspected since the Imja glacial lake was drained in 2016, leading to significant concerns about potential flooding disasters.

Local Sherpa communities informed the BBC that no maintenance has occurred, resulting in siren towers left rusting, with some even having their batteries stolen. Additionally, the satellite data responsible for monitoring the lake's water levels has proven unreliable, hindering timely mobile alerts to the villages downstream.

The Imja lake, situated at an altitude of about 5,000 meters (16,400 feet), remains a critical point of concern due to the rapidly melting glaciers influenced by global warming. Experts warn that glacial lakes like Imja can dangerously expand and pose flooding threats, having experienced at least five significant flood events in the past 50 years.

Villagers are voicing their frustrations, noting that although they were promised annual inspections, the officials have not visited in years. For instance, Ang Nuru Sherpa, a community leader, expressed disbelief at the state of the siren towers, stating, “Going by the state of the siren towers, we don’t expect to get any flood warning from them even when Imja lake bursts out.”

Officials from Nepal's Department of Hydrology and Meteorology (DHM) concede that budget constraints have hindered maintenance efforts. There have been proposals for funding from hydro-power providers downstream; however, these have not come to fruition.

Despite the growing risks, the acting director general of the DHM, Archana Shrestha, acknowledged a lack of resources directed towards the Imja lake system, explaining that recent funding and focus have been diverted to other projects.

As the spring climbing season approaches and more than 60,000 tourists begin to visit the Everest region, officials stress the urgency of addressing these neglected early warning systems, not just for local communities but also for the safety of climbers and tourists in this vulnerable landscape.
