Bystanders say the man's kayak overturned at about 1:30 p.m. and he was pulled from the water shortly after, unresponsive. Rescuers performed CPR until paramedics arrived and took over, then transported the man to an area hospital where he was pronounced dead.  Police have classified the case an unattended death.
