(CBS DETROIT) – The Oakland County Sheriff’s Office is investigating two separate incidents at North Commerce Lake and Union Lake.
According to the sheriff’s office, search and rescue personnel were called to North Commerce Lake at approximately 5:57 p.m. for a man floating unconscious in the water.
Authorities said the 20-year-old Commerce Township man was on a pontoon boat near a sandbar in the lake when he dove and struck his head on the lake bottom, about 4 feet underwater. The man, who was not wearing a life jacket, was taken to a hospital with serious injuries.
Researchers suspect that alcohol played a role.
At approximately 5:43 p.m., the sheriff’s office reported that a 32-year-old Waterford Township man was riding a personal watercraft when he fell off. The personal watercraft continued for a short distance before striking a 24-foot pontoon boat.
According to authorities, a 29-year-old woman was lying on her back on the bridle of the boat when it was struck. She suffered minor injuries and refused treatment at the scene.
Alcohol does not appear to be a factor.
