Update: 4:15
A 911 call was made by a concerned citizen who saw a windsurfer drifting about 500 metres off the beach. Police and fire responded and reached the man in the lake who told them he was not in danger.
The rescue team brought the man to shore, though he was arguing he was ok and should have been left alone.
