Yulia K. and her brother were in the tourist group from Moscow which set sail on the lake before the storm hit on Saturday. She was separated from him and thrown onto the lake's shore, where she lay unconscious until the next morning.
When she woke up, Yulia K. walked up the shore towards the village of Kudama. On the way to get help, she came across another young boy who had been badly injured in the disaster.
"First we thought that she just got lost. But when she told us what happened, we called rescue services and police at once," LifeNews reported Kudama resident Aleksandr said.
"She was just walking along the shore. She knocked at three houses but no one was in, and then she got to us."
According to information from the Emergencies Ministry, 47 children aged between 12 and 15 years old, accompanied by four adult instructors, were on the three boats that capsized.
At least five children have been hospitalized with hypothermia, and 25 children have been sent to Karelia's capital city of Petrozavodsk. The Russian General Prosecutor's office has opened a criminal investigation.
