Authorities responded to a call around 1 PM Friday to reports of man yelling for help from a sinking boat on the west side of Shell Lake.
Attempts to rescue the man were unsuccessful as he was in deep water just off of a sandbar.
Divers were able to locate John Frisco of Clear Lake, who was pronounced dead at the scene.
Early investigation shows it is unclear how or why Frisco's kayak capsized.
The incident has been turned over to the Washburn Department of Natural Resources.
Several agencies from Washburn County, Shell Lake and Spooner responded to the incident.
