In episode one of the Undisclosed podcast about the case of State v. Pamela Lanier, drowning expert John Fletemeyer states that in 40 to 50 percent of open water drownings the water is not over the victims head. Fletemeyer advises rescue workers to yell at drowning victims to just “stand up!”
Another interesting statistic from this website, is that 80% of drowning victims in the United States are male.
