Teenage girl seriously hurt after falling out of boat on southern Alberta lake

BROOKS, Alta. - A 17-year-old girl is in hospital after falling out of a boat on a southern Alberta lake and getting hit by the propellor.

RCMP says the girl suffered serious injuries to her leg and torso in the accident on the Newell reservoir near Brooks on Friday night.

Police say her injuries could have been more severe if not for the quick actions of the boat's operator, an 18-year-old woman, who came to the teen's aid.

The girl was taken by air ambulance to hospital in Calgary.

RCMP say neither of the boat’s occupants was wearing a life jacket.

Alcohol has been ruled out as a possible factor.
