The body of the 46-year-old man from Warrnambool was found about midday on Monday, about 500 metres from where the car was submerged. It is believed the car entered the water from Mahoneys Road.
Initially, it was not clear how or why the man’s car came to be in the river, but on Monday afternoon police added to the incident to the road toll, suggesting they believe the car crashed.
“The death is not being treated as suspicious and police will prepare a report for the coroner,” Leading Senior Constable Paul Turner said.
Victoria’s road death toll now stands at 117, up from 103 at the same time last year.
Anyone with information about the incident is urged to contact Crime Stoppers on 1800 333 000.
