A Wisconsin man is fighting serious injuries after a boating accident over the weekend.

According to the Highway Patrol’s water division, 23-year-old Zach Schemming of Racine, Wisconsin was traveling downstream at the 10.2 Mile-marker of the Main channel when he struck a large wake.

That caused him and his passenger, 34-year-old Cody Kallenback, also from Wisconsin, to strike the inside of the boat.

Schemming was life-flighted to University Hospital in Columbia while Kallenback was taken to Lake Regional.
