The Huron County OPP, Huron County Paramedics and Bluewater Fire responded to the incident Saturday afternoon just north of Bayfield.
First responders arrived around 2:20 pm on June 10th to a beachfront address in Central Huron to an incident involving a pleasure craft operator in distress.
Life saving measures were performed on the individual and they were brought to shore.
A 32-year-old Bluewater resident was pronounced deceased at the scene.
