Forty two Glacial lakes of Koshi Province face critical risk, say experts

A recent report released by the International Centre for Integrated Mountain Development (ICIMOD) has revealed that 42 glacial lakes in Koshi Province are facing a critical risk.

During a discussion held on Friday in Khandbari, headquarters of Sankhuwasabha of Koshi Province, ICIMOD expert Sharad Prasad Joshi sharing insights from the 2020 report on ‘Risks arising from rapid changes in Nepal’s glaciers and glacial lakes,’ revealed that out of a total of 2,069 glacial lakes in Nepal, 42 located in the Koshi region are classified as highly at risk.

He warned that a potential burst of a glacial lake could lead to catastrophic loss of life and extensive damage to infrastructure, underscoring the importance of heightened vigilance and preparedness. According to Joshi within Sankhuwasabha, four glacial lakes, including those in the Bhotkhola and Makalu areas, are categorized as high-risk.

Notably, the Tallopokhari glacial lake in the lower Barun area is deemed the most vulnerable. According to Joshi the lake is approximately three kilometers long and around 206 meters deep with surrounding depths ranging from 15 to 25 meters. In partnership with the Department of Hydrology and Meteorology and UNDP Nepal, risk reduction strategies are being developed for these four glacial lakes, he pointed out.

Additionally, a large pond situated in lower Barun is part of this initiative. If a glacial lake were to burst, numerous settlements and infrastructure in the Arun Valley would face immediate risk, according to Joshi. He also noted that 13 glacial lakes originating from the Tibet region could pose a threat to the northern areas of the province.

At the event, Neera Shrestha Pradhan from ICIMOD said that women, children, and the elderly are often the most affected during disasters, prompting the implementation of programmes aimed at raising awareness and building capacity among these vulnerable groups.
