Sikkim: Here's why the Chungthang Hydro-dam breach is a big deal

Guwahati: As per reports, major flooding in Chungthang around 1 am on October 4 quickly spread to other districts, causing significant damage to public property and infrastructure. The flooding was caused by a glacial lake outburst of the South Lhonak Lake in North Sikkim.

Flash floods have majorly disrupted communication networks in Chungthang and Mangan districts and districts have initiated evacuations in vulnerable areas in response. Reportedly, 23 Army personnel are missing at the time of filing this report.

The breach of Sikkim’s Chungthang Hydro-Dam has sent shockwaves through the region, raising concerns about its implications.

It is to be noted that the dam is an integral part of the 1200 MW mega Teesta Stage III Hydro Electric Project, developed by Teesta Urja. With a gross head of 817 metres and a net head of 778 metres, it stands as a crucial source of power generation.

The breach has led to the release of an astonishing 5.08 million cubic metres of water from the hydro reservoir; and this deluge is now hurtling down the mountains, causing alarm among nearby communities.

The scale of this breach is a matter of grave concern, with potential consequences ranging from environmental damage to the displacement of residents downstream.

The Chungthang Hydro-Dam breach underscores the importance of stringent safety measures and ongoing maintenance in the hydroelectric sector. It serves as a reminder of the potential risks associated with large-scale infrastructure projects and the need for robust disaster preparedness.

Authorities are currently assessing the situation and working tirelessly to mitigate the impact of this disastruous breach.
