On Thursday, around 6:40 pm, Outlook RCMP responded to a call of a possible drowning.
It was reported that a man and a woman were swimming in Lake Diefenbaker, when the woman made it back to shore, but could not find the 35-year-old man in the water, or on the shore.
He has yet to be located and was last seen in the Danielson Provincial Park.
Outlook RCMP and several other organizations began searching the lake and shoreline by boat, ground, and air.
The search continues today.
