Ontario's Ministry of the Environment, Conservation and Parks says more than a hundred dead fish that appeared in the Ottawa River near Cumberland are coming from the Lièvre River in Quebec, but it has yet to determine the reason for the die off.

On Monday, Carie McBain, who lives next to the Cumberland-Masson ferry, went to see for herself after noticing a photo of dead catfish on a social media site for Cumberland residents.

When you see a large number of fish and a variety of species, that is concerning and indicates something is going on.

"All you could see were spots bobbing all over the water as far as you can see, and we went up to them and saw big catfish with really huge big bellies, and perch, walleye, rock bass and carp," McBain said. "It was gross."
