Warmer than usual water temperature is making it challenging to build ice in some sections of the Rideau Canal Skateway, according to the National Capital Commission (NCC).
“We noticed more vapour than normal…water discharging more heavily…we believe it seems to be warmer water than usual,” says Bruce Devine, senior manager of the Rideau Canal Skateway.
The NCC says in late December 2017 and again in December 2018 while the weather was very cold, the water was warmer and the ice wasn’t growing at the expected pace.
