The search for a missing boater continued Monday along the Sauble River near Park Head.

However, police say they have "scaled back" their involvement in the search for the missing boater in Bruce County.

OPP used a helicopter on Sunday to help with the search, but the results were negative.

Since then fewer people have been involved in scanning the Sauble River south of Helpworth, but family  members are continuing to search.

Police say the boater was alone and in a dinghy. The person was last seen early Thursday evening.

The name of the missing party is not being released at the request of the family.

Police continue to ask the public for assistance and anyone with information can call 1-888-310-1122.
