Police divers are being called in to search for a Regina man who went swimming in a Saskatchewan lake and didn't surface.
RCMP say the 20-year-old man was with a female Tuesday morning when they went into Last Mountain Lake near Rowan's Ravine Provincial Park.
They say he went under the water but failed to come back up.
Despite bad weather, conservation officers mounted a search effort but were unsuccessful in finding any sign of the swimmer.
The woman was taken to hospital as a precaution.
The man's name has not been released.
