Quebec’s Ministry of Environment says a hydroelectric dam on the Lièvre River is responsible for thousands of dead fish.

Ministry officials say an over-saturation in gas in the water at the Brookfield Hydroelectric Dam was killing the fish.

“It’s a phenomenon when there’s too much air too much gas in the water,” said Michel Rousseau, Quebec’s assistant deputy minister of environment.

“When a fish comes in contact with this, it can die rapidly”

Rousseau said the water became too saturated with tiny air bubbles in a phenomenon called supersaturated dissolved gas. The fish then die from gas bubbles disease, or a “gaseous embolism”.
