Expedition to Assess High-Risk Glacial Lakes in Sikkim Reaches Tenchungkha Lake
Lachung, Sikkim, September 2, 2024 — A critical expedition aimed at assessing the vulnerability of six high-risk glacial lakes in Sikkim has successfully reached Tenchungkha Lake, located at an altitude of 15,700 feet in Lachung. The mission, which commenced on August 31, was inaugurated by Lachen Mangan legislator Samdup Lepcha and marks a significant step in evaluating the potential dangers posed by these glacial bodies.
The expedition team, accompanied by representatives from the Lachung Dzumsa, embarked on this endeavor with a deep respect for the spiritual significance of the region. Traditional prayer ceremonies, led by Lachen monks at four different locations, set a solemn tone for the journey, emphasizing the cultural and spiritual importance of the lakes to the local Sikkimese population.
Dr. Sandeep Tambe, the expedition leader, along with the Dzumsa, conducted a pre-departure briefing to ensure the team adhered to protocols and respected the sacred nature of the site. The mission has received crucial support from the Indo-Tibetan Border Police (ITBP), which facilitated the team’s ascent and operations.
At Tenchungkha Lake, the team carried out essential scientific tests, including Ground Penetrating Radar (GPR) assessments, Electrical Resistivity Tests, geo-morphometry, and lake discharge measurements. These evaluations are crucial for identifying potential risks and formulating necessary mitigation strategies to prevent glacial lake outburst floods (GLOFs) and other related disasters.
The 15-day expedition, scheduled to conclude on September 14, is set to cover additional high-risk lakes including Khangchung Chho, Lachen Khangtse, Lachung Khangtse, La Tsho, and Shako Chho. Given their precarious locations and the changing environmental conditions, these lakes are of significant concern, and the findings of this expedition will play a pivotal role in shaping future disaster prevention efforts in the region.
