Four days after a massive landslide blocked Sun Koshi River in Nepal and created a huge lake, the threat of large-scale flooding if the artificial dam breaks still remains.
The landslide had brought down huge rocks and earth and created a big dam blocking flow of the river nearly 120 kms northeast of Kathmandu.
The blockade created a large lake spread over nearly 4 km.
On Monday, Nepali army carried out two more controlled explosions at the site in a bid to clear the blockade and allow the accumulated water to flow. But the rate of outflow is slow.
“Since there is threat to areas lying downstream, we are taking care to ensure that the water is allowed to flow in a controlled manner to reduce possibility of further destruction,” said an army release. If the dam breaks or the blockade is removed suddenly there is threat of large scale flooding in five districts lying downstream in Nepal and several parts of north Bihar.
The blockade has killed 33 persons in Jure and Mankha villages of Sindhupalchowk district and over a 100 are still missing. Though rescue efforts are on all of the missing are feared dead.
Due to the explosions the inflow of water was calculated at 190 cusecs and the outflow as 204 cusecs. Army is consulting experts and trying to remove the blockade in a slow and controlled manner. A team of Indian experts who visited the site on request from the Nepal government appreciated the measures taken by the Nepali Army.
