A dam in southern Norway partially burst Wednesday following days of heavy rain that triggered landslides and flooding in the mountainous region and forced downstream communities to evacuate, officials said.
Authorities initially considered blowing up part of the dam at the Braskereidfoss hydroelectric power plant on the Glåma, Norway’s longest and most voluminous river. The idea was to prevent communities downstream from being inundated by using a limited, controlled blast to release pressure on the dam.
But that proposal was scrapped after water later broke through the structure, police spokesman Fredrik Thomson told reporters.
“The damage from a possible explosion of the concrete plant would be so great that it would serve no purpose,” Thompson said.
Now officials are hopeful that they will see a gradual, even leveling of the water, Thompson said.
Norwegian Prime Minister Jonas Gahr Støre warned that flooding would continue to be a threat as excess water flows downstream.
The dam’s generators stopped working early Wednesday after a power grid failure, plant operator Hafslund Eco said in a statement.
An automatic system that should have opened the floodgates to release water failed.
