A Minneapolis man fell from a pontoon in a northern Minnesota lake and had his arm "severely lacerated" by the propeller and lost consciousness, authorities said.
David Cass, 30, of Minneapolis, is in the intensive care unit of Sanford Medical Center in Fargo, a hospital spokeswoman said Friday. She did not have a specific condition for Cass.
Early Wednesday afternoon, Cass was operating the pontoon on Lake Belle Taine, about 11 miles east of Park Rapids, and had two passengers along, according to the Hubbard County Sheriff's Office.
Cass moved to the front of the pontoon, fell into the lake and was struck by the propeller.
Sheriff's deputies and medical personnel called to the scene found Cass "unconscious and with a severely lacerated arm," the Sheriff's Office said in a statement.
After first responders began resuscitation efforts, Cass was flown to Fargo for treatment of "life-threatening injuries," the statement added.
A Sheriff's Office official said alcohol "may have been a factor" leading to Cass' injuries.
This incident comes as the state Department of Natural Resources and other agencies in the state are enforcing "Operation Dry Water" starting Friday and continuing throughout the weekend in hopes of cracking down on boaters navigating while intoxicated or under the influence of drugs.
