A man is missing and presumed drowned in Trafalgar Bay on Northern Lights Lake.

The Thunder Bay detachment of the OPP said the man went missing during a fishing trip that began at Gunflint Lodge in Grand Marais, Minn.

According to the OPP, a woman and a man police described as "an experienced guide" navigated through a series of portages to arrive at Trafalgar Bay and spent Thursday fishing. Police said both are employed by the lodge.

As they were headed back to Gunflint Lodge, the boat struck something in the water in the northwest corner of Trafalgar Bay and the two were thrown from the boat. 

The man was not wearing a life jacket and did not resurface from the water, police said.

He was reported missing shortly after 10 p.m. Thursday after a cabin owner in the area found the woman alone and wet on an island. She was wearing a life jacket  and was able to swim to an island.

The Thunder Bay OPP marine unit searched for the man through Friday. By Saturday, though, the OPP underwater search and recovery unit was en route and was expected to assist with the search.

Police continue to investigate the incident.
