A 15-year-old boy and a 12-year-old girl were found drowned by emergency personnel who pulled them from the Wabigoon River in Dryden, Ont., on Thursday, said police.

The two were seen going into the river but never resurfaced and were pronounced dead in hospital, according to an Ontario Provincial Police (OPP) media release Friday.

Police, Dryden Fire Service and Emergency Medical Services (EMS) were at the scene to help, said the release, which added that police are investigating.

It said the names of the two young people aren't being released to protect the privacy of their families. 

"The OPP would like to thank members of the public who provided assistance." 

Dryden mayor extends condolences, urges water safety 

Dryden Mayor Jack Harrison said city council extends its "deepest condolences" to family members of the two.

Harrison said he's grateful local first responders went into action quickly, and commended their professionalism and compassion. 

"This tragedy reminds us all of the preciousness of life and the importance of looking out for one another." 

While northwestern Ontario lakes and rivers are a popular attraction, Harrison said, it's important to remember potential dangers. 

"In the summer, with the incredible amount of water that we do have in this area, it's beautiful to be on and to take part in, but we do have to be very cognizant of the dangers of water, and being around water and take all precautions."

Anyone with information that could assist OPP in the investigation is asked to contact them at 1-888-310-1122.
