Rescue crews are trying to find a missing boater in Lake St Clair.

Lakeshore OPP were called out just after 3:30 yesterday afternoon and say a 58-year-old man had gone out fishing near Stoney Point.

A kayaker came across a small, unoccupied vessel on a sandbar and called police.

Authorities say the missing man has a medium build, green eyes, short grey hair, goatee, and glasses. He was last seen wearing a blue two tone tank top and light blue shorts.

The Essex County OPP Marine Unit, Chatham-Kent OPP Marine Unit, Joint Rescue Co-ordination Centre are involved in the search, both in the water and from above.
