Saw quite a few pictures on Twitter last night. Very concerning to say the least.
That area of the river sees an annual die off..they primarily come down from upstream. With all the flooding this spring and how wild and extremely dirty the water was , it's not surprising there was a large kill off.
I saw on the news this morning that there may be more to it than just the usual spring die-off.....still under investigation...

At this point, it's believed that the fish died in the Du Lievre River in western Quebec and then flowed downstream into the Ottawa River. Lack of oxygen is believed to be a key factor in the deaths.
"There's a wide variety of factors that could be causing that, because there's such a wide variety of species," said Patrick Nadeau, the executive director of watershed protection group Ottawa Riverkeeper.
Nadeau speculated that the lack of oxygen could have been caused by some sort of spill or leak into the river. Test results that could shed light on the mystery are expected to be available within days.
A spokesperson for Quebec's environment ministry told CTV News Ottawa that it was not aware of any spills in the river within its jurisdiction.
update:
Quote:
There is alarming new information tonight about what may have killed hundreds of fish along the Ottawa and Lievre rivers.
Officials are looking at whether a toxic chemical spill may be to blame.
Quebec environmental teams found "acute intoxication" was responsible for the die-off that affected several different species.
It was not an infectious disease; the fish were exposed to something toxic in their environment.
The ministry was out on the water again yesterday and found no more dead fish.
They say the water is again safe for fishing.
Thanks for the update.
There has been no more news on this. I wonder what the outcome was.
It's been on and in the news since the 10th...some delays waiting for the tox results. No news if Que is investigated the source of the toxin.Quote:

Still no results but more dead fish.
Sounds like they still haven't identified the toxin. Once that is known they can do a better investigation of who along the river could have dumped it.Quote:

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. :)Quote:

Well they have a smoking gun ! Thank buddy for getting pictures becasue it looks like they're going to deny any wrong doing.

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.

I don't think my wife will let me visit Christina Succi's twitter account HaHa..Quote:

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”.
