RCMP are searching for a 59-year-old Calgary man who did not return from a fishing trip on Shuswap Lake this week.
John Poole was reported missing Tuesday and police are now combing the area around Eagle Bay.
Poole's boat was found after it had run aground with the motor still in gear and all the rigging and fishing lines still engaged.
His family says Poole is very experienced on the water.
The average depth of Shuswap Lake is 433 feet and it can reach depths of more than 800 feet in some parts.
