Well the optimists (like me) were wrong – the water level of Lake Ontario at Cobourg has now set a new record and according to the GRCA, it has not finished rising yet (see GRCA Flood warning below). The graph below shows the peak level from each day and on 29 May the level was 8.3 cm above the record set in 2017 (that’s 3.25 inches). On May 30, the Marina fuel dock is still covered in water although thanks to some work by the Marina, it’s still operational. In fact Julie at the Marina said that other than supply of electricity to boats, Cobourg’s Marina is fully open for business – this despite the fact that many other Marinas have closed. The Beach is also flooded and virtually unusable. Dredging operations have now resumed after a mechanical problem with the dredge so that also makes a mess of the beach.
Although there are pumps working in the driveway of the Condos on Third Street, there is no flooding in their basement parking – it’s just a precautionary measure due to high ground water levels.
A flood warning is still in effect but apart from the GRCA flood warning, the only official data on water levels is from Fisheries and Oceans Canada at the link below. The official reason for the high levels continues to be the need to protect downstream from flooding due to water into the St. Lawrence from the Ottawa river. It seems that flooding along the shores of Lake Ontario is the lesser of two evils. With “100 year floods” happening two years apart, I haven’t heard any attempt to forecast what will happen next year.
Yesterday, Global News recorded interviews with Mayor John Henderson and Marina Manager Paul Gauthier – see the video below. Preceded by an advert.

Note that the peak water level on May 30 was 90 cm above the long term average (mean) level. That’s almost 3 feet! [Following note added 31 May]. Note also that the graph for 2017 is the mean level whereas the 2019 numbers are peak which are affected by wind and will be higher than the mean. Other reports on water level are using mean numbers. But the pictures tell the story….
Below are photos of the Marina and the beach on May 30. Quite foggy
