Dead fish on Ottawa River near Rockland

[awndray]

I'm anxious to find out what toxins are killing these fish. Theres a paper mill and a cannabis grow up nearby. I wouldn't be surprised if they have anything to do with it.

Wouldn't that be a hoot...discharge from the new legal grow -ops facility killing the environment.

Third time's a charm? You would think that with sampling from three events they should be able to figure out what the problem is.

It finally seems like they're getting to the bottom of this. Let's hope they can prevent any more fish from dying. I'm not holding my breath on the government handing out fines to those responsible though.

Quebec minister of the environment has confirmed that the Brookfield Hydroelectric Dam on the Lièvre river is behind all the dead fish. Their operation has contributed to a supersaturation of dissolved gas, essentially too much oxygen in the water which killed many fish. For those interested, Christina Succi of CTV news has some information available on her twitter account.

So the problem caused to fish to suffocate...

The vice-president of public affairs and sustainability for Evolugen appeared to attribute the high gas levels to this spring’s flooding, saying in a statement to CTV News:

"This spring's extraordinary flooding and high water flows caused unusually high levels of debris in the Lièvre River which has resulted in more frequent clearing of debris than the norm at our facility," Vanessa Pilotte wrote.

“Our investigation is ongoing and we continue to collaborate with all government officials.We operate to the highest standards globally and comply with all laws in the jurisdictions in which we operate. This is an unprecedented event not seen in our decades of operations.

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”.
