Glacier breaks in Uttarakhand's Chamoli

An avalanche following a glacial burst in Uttarakhand's Chamoli district, about 650 kilometres from here, on Sunday morning caused a massive flood and damaged two hydro power projects on Rishiganga and Dhauliganga rivers trapping hundreds of workers at the projects, and triggering alert in the districts along the Ganga river in neighbouring Uttar Pradesh.

According to reports, around 100 to 150 workers, who were at work at the two projects, were 'missing'.

Officials in Uttarakhand's capital Dehradun said that the under construction 24 MW hydro power project at Reni village in Chamoli district was damaged after the avalanche triggered after the Nandadevi Galicer broke causing a massive flow of water in Rishiganga river. The huge water, which was mixed with the debris, then damaged another under construction hydro power project at Dhauliganga river near Tapovan, about ten kilometres away.

As the flow of water in the tributaries of the two rivers increased suddenly, an alert was sounded in the areas near the rivers downstream from Tapovan to Haridwar and the people had been asked to move to the upper regions.

In a series of tweets in Hindi, Shah also said teams of the National Disaster Response Force (NDRF) have been deployed for rescue and relief operations of the affected people while additional troops of the force are being airlifted from Delhi.

NDRF teams have left for rescue operations. Every possible help will be provided to 'Devbhoomi'," he said.

Shah said the central government is constantly monitoring the situation in Uttarakhand.

"Some more teams of NDRF are being airlifted from Delhi and sent to Uttarakhand. We are constantly monitoring the situation there," he said.

An alert was also sounded in the districts situated on the bank of the Ganga in Uttar Pradesh and boating was banned in the river until the situation improved, the officials said in Lucknow.
