A woman remains in critical condition after being pulled from the water off Rondeau Provincial Park.
Chatham-Kent OPP was called to Lakeshore Road shortly after 2 Thursday afternoon after a woman who had fallen off an inflatable raft failed to resurface.
Some people on shore swam out to help and pulled the unconscious woman from the water.
Bystanders performed CPR until emergency responders could take over and the woman was taken to hospital.
