In Gangwon-do Province, three boats capsized this morning, leaving at least one person dead and five others missing.
Two people have been rescued.
At around eleven-thirty AM today, near Uiam Dam, a police boat started to sink after being caught on a wire.
People reported to be maintenance workers from the dam and another man went to the rescue onboard two boats, but all three boats ended up sinking.
One person was saved as the boats went down and another was rescued later, but one person's body was found 20 kilometers down river.
It's believed that they were swept away so fast because the nearby dam had been releasing water.
