5 dead, 23 soldiers missing as flash flood wreaks havoc in Sikkim

Gangtok: Five persons died and 23 army personnel went missing on Wednesday after a cloudburst over Lhonak Lake in north Sikkim triggered a flash flood in the Teesta River basin, officials said.

The flood that started around 1.30 am was made worse by the release of water from Chungthang dam, they said.

“Five bodies have been recovered from Golitar and Singtam region, while three persons were rescued from Golitar,” Gangtok Sub-Divisional Magistrate (SDM) Mahendra Chettri said.

“A steel bridge at Singtam, known as Indreni bridge, 30kms from the state capital Gangtok has been completely washed away by Teesta river water early Wednesday,” another official said.

The Sikkim government, in a notification, said the natural calamity has been declared as a disaster.

The release of water from the Chungthang dam led to a sudden increase in water levels up to 15-20 feet high downstream, defence spokesperson Lt Col Mahendra Rawat said.

“Twenty-three Army personnel have been reported missing and 41 vehicles submerged under the slush,” he said.

Several towns, including Dikchu, Singtam and Rangpo located in the Teesta basin, have also been flooded with the upsurge in the river.

Meanwhile, all schools located in Mangan, Gangtok, Pakyong and Namchi districts will remain closed till October 8, the education department said in a circular.

Parts of National Highway-10, the main link between Sikkim and the rest of the country, were washed away, the officials said, adding, a flood alert has been issued for North Bengal and Bangladesh through which the Teesta flows.

Two other bridges, Baluatar and another near the Lanco Hydel power project, have collapsed due to the spate in Teesta since Tuesday night, they said.

The administration has set up a number of relief camps, where hundreds are taking shelter, the officials said.

The Sikkim State Disaster Management Authority stated that a "cloudburst in portions of Lhonak Lake, which caused the rise of water levels with very high velocities downstream along the Teesta River basin in the early hours of Wednesday" damaged many establishments in Mangan, Gangtok, Pakyong, and Namchi.

Chief Minister P S Tamang visited Singtam and took stock of the situation. He also held a meeting with senior officials at the Singtam Nagar Panchayat office and asked them to keep vigil.

In a post on social media, Tamang said his thoughts and prayers are with all during this difficult hour.

“In these challenging times, I want to extend my heartfelt support to all the victims and their families affected by this unfortunate event,” he said.

“I want to assure you that the government is fully committed to providing all necessary assistance and relief to those in need. We understand the magnitude of the situation and are mobilizing all available resources to ensure the safety and well-being of our citizens. Our dedicated teams are working day and night to address the immediate concerns and challenges posed by this calamity,” Tamang said.

In West Bengal, torrential rain in the last few days, besides increase in the water level in the Teesta river, affected several places in Kalimpong, Darjeeling, Alipurduar and Jalpaiguri districts, where the administration has started evacuating affected people to safer locations, state government officials said.
